1
00:00:00,000 --> 00:00:16,920
Thank you for the scientific help on Apollo 16.

2
00:00:16,920 --> 00:00:22,240
I personally think that you all did a very credible job in helping the science support

3
00:00:22,239 --> 00:00:31,359
room and pre-flighting to get all the experiments ready to prepare the crew and the flight for Apollo 16.

4
00:00:31,359 --> 00:00:37,119
I think that looking back at it now we can say we had a very successful mission that we attained

5
00:00:37,119 --> 00:00:42,159
a tremendous amount of information from the flight. I know that the rock boxes back there

6
00:00:42,159 --> 00:00:48,480
at the curatorial facility are bursting at their seams and the jealousers are going to have a lot to do.

7
00:00:48,479 --> 00:00:55,599
I think also that because of the problems that arose and the necessity to change the flight plan that

8
00:00:55,599 --> 00:01:00,559
you responded quite well to get the maximum science out of the time that we had available.

9
00:01:00,559 --> 00:01:07,000
I realize that in all of our flights there hasn't been one flight yet that ran according to schedule.

10
00:01:07,000 --> 00:01:15,120
And I am very sure that Apollo 17 will be in the same boat that we will have to change things real time

11
00:01:15,120 --> 00:01:22,800
to get the maximum science out of the mission. And I think the response on this flight was superb.

12
00:01:22,800 --> 00:01:32,000
Now today the briefing here is in two parts and four two purposes. First of all I like each principal investigator

13
00:01:32,000 --> 00:01:42,400
to briefly describe the results so far obtained from his work. This is to sort of educate the crew

14
00:01:42,400 --> 00:01:47,840
on what we obtained so far from Apollo 16 so that they might have information along that line.

15
00:01:48,719 --> 00:01:53,520
Also I like to have him describe any anomalies that might have occurred that we do not know about now.

16
00:01:54,719 --> 00:02:02,320
And second then we like to have the PI with the crew working with them to answer,

17
00:02:02,320 --> 00:02:08,400
have the crew answer any questions that might still be puzzling him so that he might further his

18
00:02:08,400 --> 00:02:13,760
analysis of the data. We have a lot of people to go through today, a lot of science to cover.

19
00:02:13,760 --> 00:02:18,960
So we like to keep each briefing short and we don't want to cover things that are pretty well

20
00:02:18,960 --> 00:02:25,599
that are general knowledge as of today. And we can start right out.

21
00:02:28,480 --> 00:02:31,920
First one is Palmer Dial, Lunar Service Manitometer.

22
00:02:32,399 --> 00:02:44,639
After each experimenter describes this experiment we'll have questions Palmer so we can ask the crew any questions after your particular talk.

23
00:02:44,639 --> 00:02:49,599
There's a mic right over there.

24
00:03:02,879 --> 00:03:04,479
You may set, stand, anything you want to do.

25
00:03:10,239 --> 00:03:15,439
I guess the main functions of both instruments went normally.

26
00:03:16,639 --> 00:03:22,239
I'd like to cover both the portable and the surface if that's acceptable.

27
00:03:22,320 --> 00:03:33,840
The all-sep instrument, the surface magnetometer that you deployed first looked like it went according to plan.

28
00:03:34,879 --> 00:03:42,240
The field that we measured as soon as it was turned on, I think it was turned on about 15 minutes or so after you deployed it,

29
00:03:42,240 --> 00:03:46,320
was 230 gamma in a downward direction.

30
00:03:46,799 --> 00:03:56,000
At that particular time that was the highest field that we'd ever measured on the lunar surface.

31
00:03:59,840 --> 00:04:04,959
The calibration of the instrument went straight forward.

32
00:04:04,959 --> 00:04:08,240
We did do a gradient determination of the field at the site.

33
00:04:08,240 --> 00:04:12,640
At that site survey as we call it, function normally.

34
00:04:17,040 --> 00:04:20,960
Thermal control subsystem is the best that we've put on the moon so far.

35
00:04:20,960 --> 00:04:33,439
We have a delta T from lunar day to lunar night of 51 degrees centigrade, which is a factor of two better than our Apollo 12 thermal subsystem.

36
00:04:33,600 --> 00:04:45,519
The leveling of the device was, I noticed in the photograph yesterday, that the bubble level was right in the center of rain.

37
00:04:45,519 --> 00:04:58,000
The level sensors that we have are accurate to a quarter of a degree and they show that the instrument is level to one degree accuracy right now.

38
00:05:04,240 --> 00:05:06,719
The instrument has new sensors in it.

39
00:05:06,719 --> 00:05:14,240
These are more stable and it's really the first chance we have of doing network type measurements of the fields on the moon.

40
00:05:14,240 --> 00:05:20,079
We do see whole moon, we have seen simultaneous data now from 15 and 16.

41
00:05:20,079 --> 00:05:27,759
We see the magnetic fields due to any currents that are driven in the entire lunar sphere.

42
00:05:27,759 --> 00:05:38,000
For the first time experimentally, we have always made that assumption that we've got an instrument that's setting on a one point on the sphere and that we're looking at the properties of a whole sphere.

43
00:05:38,000 --> 00:05:41,839
We had some experimental evidence that that were the case.

44
00:05:41,839 --> 00:05:53,839
Now we have unambiguously shown with this second instrument that is indeed the case and that the assumption is correct that we are looking at a whole spherical response of the moon.

45
00:05:53,839 --> 00:05:57,279
You mean you're seeing 80 currents all the way through the moon?

46
00:05:57,359 --> 00:06:10,959
We're seeing any currents that go around the whole sphere but with these new sensors now and with long-term data, what we're going to try and do is look as you say right at the center of the moon as they go all the way through.

47
00:06:10,959 --> 00:06:23,359
Now that's what we're waiting for during the lunar night is a nice step function and a long term both before and after so we can see these currents diffuse right through the center of the moon.

48
00:06:28,159 --> 00:06:38,559
The other thing that I think that is unique about this instrument that now we have a chance to look at the as-muteal variations in conductivity.

49
00:06:38,559 --> 00:06:52,239
We can not only look at radial dependence of the electrical conductivity and calculated temperature but now we can look at the as-muteal or angular variations between Apollo 15 and Apollo 16 site.

50
00:06:52,800 --> 00:07:01,120
And that spread is foreign now so that we ought to be able to extrapolate those measurements to a great circle around the whole moon as-muteal dependence.

51
00:07:02,160 --> 00:07:04,720
The portable magnetometer was really exciting.

52
00:07:06,960 --> 00:07:20,800
First of all, the first field I think you measured was 180 gamut down and in the Kaley it looked like that all the fields were in essence pointed in a downward direction and

53
00:07:22,240 --> 00:07:37,759
at the Alsap site it was 230 gamut up near Spook it was 180 gamut and then on the other side of the limb where you parked the rover at the last station it was 120 gamut.

54
00:07:37,759 --> 00:07:44,000
And at that station you put a rock on it and it looks like we measure about 4.7 gamut from that rock.

55
00:07:44,000 --> 00:07:48,560
So the rock was large enough and it hasn't large enough at the moment that it looks like we did see a difference.

56
00:07:49,120 --> 00:08:09,759
And these measurements do have an air bar on them that is like plus or minus as much now as 5 to 10 gamut because the solar wind and all the other inductive fields that are around that have to be subtracted out of the measurements from our magnetic from the tape and data reduction.

57
00:08:10,719 --> 00:08:30,959
The measurements at station 5 were pointed upward and the measurements up near North Ray Crater were pointed downward at 300 and 14 gamut.

58
00:08:30,959 --> 00:08:56,960
I think that there are some things that we could probably say making a lot of assumptions but it looks like if this highly material is older than the other it looks like that we have at least a chance of looking at the paleo magnetic history of the lunar crust from these measurements.

59
00:08:56,960 --> 00:09:26,879
The high fields indicate that either the perming source the source of this field was if it remains stable over the time period that the mario was cooling then the highly material would indicate this high field would indicate that it indeed had a time variation in its magnitude or that the mario the flooding of the mario basins or whatever caused the

60
00:09:26,879 --> 00:09:34,639
mario basins to be as they are today demagnetized the material that had been there originally.

61
00:09:36,399 --> 00:09:40,639
In other words the mario material is less magnetic it seems than this material.

62
00:09:41,360 --> 00:09:52,720
The interesting thing too is that the samples as you know are from the regolith and they've really physically been modified over the years.

63
00:09:52,800 --> 00:10:16,879
I think that the measurements that we've obtained over scale sizes in the order of 10 kilometers indicate that we're looking at a depth well below the regolith and that this is indicative of fields that were at the moon during a time period before in the order of three to four billion years ago.

64
00:10:17,360 --> 00:10:44,879
The direction and the other thing that we can say now from the measurements of the solar wind simultaneous measurements of solar wind and magnetic fields at the Apollo 12 and 15 site we can say that these high fields that you measured at the Apollo 16 site modifies drastically the direction and interaction of the solar wind with the moon at these places.

65
00:10:45,039 --> 00:11:09,679
It should channel the charged particles and either different locations asymmetrically on the lunar surface in these areas and in some cases that one could now state that the scale size of the field are large enough so that you could form a shock and actually stand off the solar wind over a small region to the moon.

66
00:11:09,679 --> 00:11:23,120
Yes that's covers both of them. Do you have any questions you want to ask to crew concerning anything about the deployment or any of the experiment that you know about.

67
00:11:23,120 --> 00:11:29,679
Parallel let me ask you what is the effect of that rock after by the big LSM did that hurt it much?

68
00:11:29,679 --> 00:11:40,639
No first where you were you parked the rover the first time in the TV camera we were extremely disturbed because the angle was such it looked like that rock was as big as the electronics box.

69
00:11:40,639 --> 00:11:59,519
It looks like that the PRAs were oriented so it was shining right into them and all the IR radiation would really heat us up during the daytime but then the other view showed that the rock was relatively small compared to the dimensions of the box and didn't affect the thermal.

70
00:11:59,679 --> 00:12:08,159
Subsystem at all and magnetically it didn't they really contain that much oriented field for doing that.

71
00:12:08,159 --> 00:12:24,959
I guess one of the things I'd like to say is this what we intended to do was we intended to drive a hundred yards away from the out in front of the lunar module with the rover and do it sort of a north-south traverse looking for the best place to deploy

72
00:12:24,960 --> 00:12:41,920
the LSM to get away from all these things. We ran into problems with the UV and that it took longer to do that last measurements and anticipated and we couldn't do that.

73
00:12:41,920 --> 00:12:52,400
And I'm sure that somebody looking at the photos can find a better place out in front of the lunar module to put the total package but I like to say that package is so big.

74
00:12:53,360 --> 00:13:00,879
And that surface was so blocky and so full of craters that under a circumstances almost blew we had to take what we got.

75
00:13:00,879 --> 00:13:09,679
I hate to say that but then man I just wouldn't believe that that surface was as rough and it's covered with blocks as it turned out to be.

76
00:13:09,679 --> 00:13:17,600
I think I could have still been walking up there with that package if I'd have been looking for a level spot. I got up on top of the ridge and I looked all

77
00:13:17,600 --> 00:13:21,600
and said well that's a good place over there and I ran over there and it didn't look any better in the place I just

78
00:13:21,600 --> 00:13:28,000
been and well that's a good place over there and I ran over there and finally after back to third time I said well look I'm

79
00:13:28,000 --> 00:13:35,360
just going to put this thing down here at best we got but it's really blocky and a lot of fresh craters there.

80
00:13:35,360 --> 00:13:36,480
Secondary.

81
00:13:36,480 --> 00:13:45,120
Well I think that if you look at at least the magnetometers I looked at each of the photos that I could find where you

82
00:13:45,120 --> 00:13:53,120
take in a picture of both the l-ceph magnetometer and the portable you picked you didn't put the thing next to

83
00:13:53,120 --> 00:13:59,120
rocks or craters on the scale size it was big enough to affect the instrument and I think that's the main criteria

84
00:13:59,120 --> 00:14:01,120
which was observed during that.

85
00:14:01,120 --> 00:14:07,120
John and you know the rationale for doing that unplanned portable magnetometer reading?

86
00:14:07,120 --> 00:14:11,120
No but it doesn't make any difference I mean we did it.

87
00:14:12,080 --> 00:14:15,120
You can't explain it in real time that's alright.

88
00:14:15,120 --> 00:14:31,120
One on a hardware the Sunsheel on the LSM the latch didn't come loose and I kept pulling the arms up to try to get that latch loose and I finally had to hold the arm down and

89
00:14:31,120 --> 00:14:39,120
get the latch loose with the other hand and then as I tried to lock the thing the latch didn't fall off it tangled up into that little wire

90
00:14:39,120 --> 00:14:49,120
that locks into the little ball and that was a almost lusted like that without locking it.

91
00:14:49,120 --> 00:14:59,120
In fact Houston said go ahead and leave it but one more little effort the thing finally dropped off and I thought I was going to disturb the level but if you

92
00:14:59,120 --> 00:15:01,120
seem like you're satisfied with the level.

93
00:15:01,120 --> 00:15:08,120
The only thing I worry about there is that we've got a level sensor in the thing and if you just stare at that you can sort of see that

94
00:15:08,120 --> 00:15:15,120
go but the the the azimuth you know when you read that shot a graph off that's the only measurement we get in azimuth ever.

95
00:15:15,120 --> 00:15:21,120
And so as long as you could you didn't disturb the twisting of it then it's fine.

96
00:15:23,120 --> 00:15:25,120
Okay thank you Paul.

97
00:15:25,120 --> 00:15:32,120
Next experimenter will be Dr. Gary Latham passing size of it experiment.

98
00:15:32,120 --> 00:15:51,120
Yes yes go ahead.

99
00:15:51,120 --> 00:16:00,120
I was going to ask one question based on the few regions of the chemical contact, the gradients from which is passed out there.

100
00:16:00,120 --> 00:16:06,120
Oh we don't have the because they got the fluctuations from salt and winter and the other is using policy.

101
00:16:06,120 --> 00:16:10,120
I'm talking about the patient.

102
00:16:10,120 --> 00:16:12,120
Sorry man.

103
00:16:12,120 --> 00:16:17,120
Actually you took the other side was taking on after you had the point of such a right.

104
00:16:17,120 --> 00:16:22,120
The three footer I think was that's correct is.

105
00:16:22,120 --> 00:16:26,120
And we didn't touch it after that.

106
00:16:26,120 --> 00:16:33,120
If there are any questions before any time after the discussion feel free to raise your hand.

107
00:16:33,120 --> 00:16:40,120
Our fun began as you know with the S4B impact on this mission.

108
00:16:40,120 --> 00:16:53,120
We also know we lost tracking on it prematurely which meant that we were not able to get the coordinates and time of the impact independent of our own measurements.

109
00:16:53,120 --> 00:17:03,120
Nevertheless we could locate it fairly well from the two near stations 12 and 14 which made it a useful impact at the greater range of the station 15.

110
00:17:03,120 --> 00:17:07,119
And we are looking at those signals now.

111
00:17:07,119 --> 00:17:27,119
I think we can say that this peculiarly high velocity mantle as we call it that we had found in the 12 and 14 region can't be a global feature unless it is exceedingly thin thin slab of this high velocity stop signals we got.

112
00:17:27,119 --> 00:17:35,119
And I must say that there is always the uncertainty that we really didn't see the first arrival up there because it was at 1100 kilometers.

113
00:17:35,119 --> 00:17:45,119
And the first signal you see is quite weak as always the uncertainty is to whether or not it is the first the fastest traveling wave in the moment and not something else.

114
00:17:45,119 --> 00:17:56,119
But if it is then this very high velocity material that we called mantle is not global or exceedingly thin layer.

115
00:17:56,119 --> 00:18:09,119
And that is because we get velocity approaching 8 kilometers per second at depths of the moon of the order of 100 kilometers not 9 kilometers per second as we had in the 12 and 14 region.

116
00:18:09,119 --> 00:18:22,119
There is also very weak evidence from that signal and I haven't convinced my colleagues of this yet know myself really but the possibility of a reflection from a very deep interface.

117
00:18:22,119 --> 00:18:32,119
Perhaps 550 kilometers deep is there and we are looking for ways to see whether or not that can be verified.

118
00:18:32,119 --> 00:18:36,119
In other words a primitive co-op perhaps some other reflector at very great depth.

119
00:18:36,119 --> 00:18:43,119
So this impact will I think provide very useful data despite the loss of tracking.

120
00:18:44,119 --> 00:18:54,119
We would have been of course much better off had been able to photograph that impact area and I understand that could tell time and orbit or clue to that.

121
00:18:54,119 --> 00:19:00,119
We did not photograph it and that is for being.

122
00:19:00,119 --> 00:19:11,119
The deployment was good I think the pictures tell the story as far as I'm concerned the instrument does get hot during the lunar day as the other instruments had.

123
00:19:11,119 --> 00:19:18,119
This has been the case in every one. I think it's a matter of just it's just not possible to keep dust off of that shroud.

124
00:19:18,119 --> 00:19:24,119
I think when you have to work that close to it and that that degrades the thermal control.

125
00:19:24,119 --> 00:19:33,119
It does not degrade the seismic data. It simply means that the controllers have more work to do trying to maintain the thermal stability.

126
00:19:33,119 --> 00:19:38,119
It's a problem we faced in every one of the missions so it's not.

127
00:19:38,119 --> 00:19:46,119
In fact I thought the deployment the configuration of the shroud that I saw and so on looked very very good.

128
00:19:46,119 --> 00:19:54,119
There's one little place where it's raised up is where the keyboard comes out underneath. It's turned on its edge a little bit.

129
00:19:54,119 --> 00:19:59,119
That of course is something of a heat loss but it's not serious at all.

130
00:19:59,119 --> 00:20:04,119
We padded it and rascal down because of the 15 problems.

131
00:20:04,119 --> 00:20:14,119
But maybe it's before a guy leaves that alseps site if he's got a problem like it. Maybe it is alseps on 17. Probably it's not.

132
00:20:14,119 --> 00:20:17,119
Alseps is on the seismic.

133
00:20:17,119 --> 00:20:28,119
Those rascally things assume some different kind of orientation than they did before we left and maybe ought to go back one more time and make sure those things are on the ground.

134
00:20:28,119 --> 00:20:33,119
I mean make sure those things are haven't changed.

135
00:20:33,119 --> 00:20:40,119
I think maybe the outgast a little and then take up a different shape.

136
00:20:40,119 --> 00:20:49,119
Well it's not only your near activities. I think when we saw that TV picture degrade on Lem Ascent.

137
00:20:49,119 --> 00:20:56,119
It's obvious that a lot of debris is being thrown around and you just can't avoid a good dusting down from that source.

138
00:20:56,119 --> 00:21:05,119
Our carefully prepared thermal services act more like black bodies than anybody figured on as a result of all this.

139
00:21:05,119 --> 00:21:11,119
And we saw your rover signals which this time provided very very interesting data.

140
00:21:11,119 --> 00:21:20,119
In that they showed another abrupt changes in signal level as you moved around.

141
00:21:20,119 --> 00:21:36,119
We're not sure yet what to make of that. We're going to work with Bill Mulberger and his crew carefully on the traverse to see whether or not we can identify specific provinces in which the signal level is quite a bit higher.

142
00:21:36,119 --> 00:21:49,119
I guess I would like to ask your impression as you were rolling along and given along the given EVAs that you you felt at given times the rover was bound to the ground.

143
00:21:49,119 --> 00:21:59,119
The rover was bouncing noticeably more than other times that might have generated higher signal levels.

144
00:21:59,119 --> 00:22:03,119
Sometimes she was off the ground or no doubt about that.

145
00:22:03,119 --> 00:22:13,119
To the south EVA2 that area was a lot rougher than the traverse route to North Rae crater.

146
00:22:13,119 --> 00:22:23,119
My impression of North Rae crater traverse once we passed Palmetto was it was really bolder free area. Very subdued old craters.

147
00:22:23,119 --> 00:22:34,119
And the rover just spent a long much like a West Texas type terrain. Whereas to the south it was really rough.

148
00:22:34,119 --> 00:22:41,119
Particularly on survey ridge when we were at Traverson that area with all the secondaries and blocks.

149
00:22:41,119 --> 00:22:52,119
We managed to be up in here quite a bit simply because there were so many secondaries and blocks that we had hit some small ones to avoid the big ones.

150
00:22:52,119 --> 00:23:02,119
The subjective opinion of mine also is that around at least it stopped 13 where we actually got off the rover.

151
00:23:02,119 --> 00:23:09,119
The regularity did not seem as loosely compacted as to the south.

152
00:23:09,119 --> 00:23:19,119
And in fact in North Rae crater at station 11 and 12 it was no more than a couple inches deep because we couldn't get the rake in without bending the times of the rate.

153
00:23:19,119 --> 00:23:37,119
So the regularity was very thin. And I don't know what that means there's a very cobbly, the disly compacted blocks under there from that were thrown out or that are now that much covered or whether we just picked some bad size.

154
00:23:37,119 --> 00:23:45,119
But we tried to rake twice and both times the only luck we had was kicking stuff into the rake. We couldn't pull the rake through the regularity.

155
00:23:45,119 --> 00:23:53,119
And you couldn't stick the tongs in either. And the tongs wouldn't go in and every other place you could take the tongs and stick in the ground and stand up for you.

156
00:23:53,119 --> 00:24:05,119
In general this area from the general character of our signals it gives the appearance of being the thickest pile of what we can quite loosely call regolith of any of the sites.

157
00:24:05,119 --> 00:24:15,119
And I guess Bob Covech will talk on his results on that. And of course we await his mortar firing to give us a little more information on that.

158
00:24:15,119 --> 00:24:29,119
Well we'll be looking at these rover signals and see if we can somehow pin them down to roughness of terrain or just what from the pictures that you took along the way.

159
00:24:29,119 --> 00:24:40,119
We now have the quiet nighttime period and we're waiting for the first moonquake of this session which ought to be, well I was hoping it would be in the last 24 hours.

160
00:24:40,119 --> 00:24:50,119
It wasn't but should be before May 12th. So in the next few days and of course with this last station we now have completed a very nice triangular array.

161
00:24:50,119 --> 00:25:07,119
The other three gave us a very narrow base thing. Now we have a thing with a thousand kilometer base line which if it lasts for as long as they appear to be lasting will give us the tools to really do the job over the next couple of years.

162
00:25:07,119 --> 00:25:13,119
And of course we'll be using that in the S4B impact from the next mission.

163
00:25:14,119 --> 00:25:24,119
I'd like to turn to one observation reported from orbit that has interested us a great deal on that was the flash that was reported.

164
00:25:24,119 --> 00:25:29,119
I haven't seen, I understand the transcript has now hasn't yet been typed.

165
00:25:29,119 --> 00:25:36,119
I haven't seen it yet. So that's my only hope for pinning down the time. If you get into about five minutes with everything.

166
00:25:36,119 --> 00:25:45,119
If you can help us pin down the time and roughly the location and we'll certainly look at our records and that would be an important piece of data if we recorded that.

167
00:25:45,119 --> 00:25:50,119
We'd like to ask was this a colored flash or a white flash?

168
00:25:50,119 --> 00:25:52,119
It's white.

169
00:25:52,119 --> 00:25:59,119
How does it differ from the kind of thing you get with a cosmic ray impact on your brain?

170
00:25:59,119 --> 00:26:01,119
I didn't see any of those.

171
00:26:01,119 --> 00:26:08,119
I see.

172
00:26:08,119 --> 00:26:15,119
You weren't crushed by flash.

173
00:26:15,119 --> 00:26:24,119
Well we're very much excited by that as far as I know it's the first report of a transient event of some nature that's been seen from orbit.

174
00:26:24,119 --> 00:26:30,119
I just have to wait for the I should have written it down and it just didn't occur to me to write it down.

175
00:26:30,119 --> 00:26:33,119
Do we get a time on it and all that again?

176
00:26:33,119 --> 00:26:35,119
It's on the DSE.

177
00:26:35,119 --> 00:26:36,119
If I ever get that all.

178
00:26:36,119 --> 00:26:42,119
Then I would correlate any information we get to the size of the faces.

179
00:26:42,119 --> 00:26:45,119
How about its persistence?

180
00:26:45,119 --> 00:26:48,119
It was just a flash.

181
00:26:48,119 --> 00:26:58,119
In the way I hadn't noticed it, I was looking at a horizon that was showing up from solar corona or zidiacolite, whatever you want to call it in that region.

182
00:26:58,119 --> 00:27:05,119
It was very shortly after we lost signal from Earth.

183
00:27:05,119 --> 00:27:18,119
I was watching stars pop up over the horizon and got this flash which was in size.

184
00:27:18,119 --> 00:27:24,119
I didn't know what it looked directly at it at the time it happened and it happened down in the side of my vision.

185
00:27:24,119 --> 00:27:30,119
But it was brighter than the brightest star that I had in the field of view at the time.

186
00:27:30,119 --> 00:27:43,119
I had that feeling that it was in physical or angular size it was equivalent to the size of the larger stars in my perceived.

187
00:27:43,119 --> 00:27:51,119
But it was just an instantaneous flash and it took us a couple of seconds for it to soak into me.

188
00:27:51,119 --> 00:27:58,119
It wasn't just a star popping up over the horizon but rather it had been distinctly below the horizon.

189
00:27:58,119 --> 00:28:02,119
Is there a way for me to get that transcript?

190
00:28:02,119 --> 00:28:05,119
I don't know if I would normally get it.

191
00:28:05,119 --> 00:28:07,119
I'm glad you asked.

192
00:28:07,119 --> 00:28:08,119
Oh that's it.

193
00:28:08,119 --> 00:28:14,119
I forgot to mention this in the opening remarks but we have about 50 copies of this technical error to ground voice transcript.

194
00:28:14,119 --> 00:28:20,119
It's right back there and for the PIs and the collis and there's a copy for you to get it back.

195
00:28:20,119 --> 00:28:22,119
That's not what you have to do.

196
00:28:22,119 --> 00:28:23,119
No, it's not me.

197
00:28:23,119 --> 00:28:24,119
It's not me.

198
00:28:24,119 --> 00:28:25,119
It's not me.

199
00:28:25,119 --> 00:28:26,119
It's not me.

200
00:28:26,119 --> 00:28:27,119
All the DSC.

201
00:28:27,119 --> 00:28:29,119
And that hasn't been completed as far as I know.

202
00:28:29,119 --> 00:28:42,119
One of the things that I'd like to mention is from orbit it appeared to me that there was a distinctly different unit up around North Ray in an area that a problem,

203
00:28:42,119 --> 00:28:46,119
I'd say a third or a half of the traverse to North Ray went across.

204
00:28:47,119 --> 00:28:53,119
And that may or may not fit in with your seismic delta.

205
00:28:53,119 --> 00:28:59,119
That at some point between North Ray and the Lemley they would cross a contact with some kind.

206
00:28:59,119 --> 00:29:00,119
Yes.

207
00:29:03,119 --> 00:29:08,119
Well it's up to Ed my thanks for a very fine deployment that's all I have.

208
00:29:08,119 --> 00:29:09,119
Thank you.

209
00:29:09,119 --> 00:29:11,119
Any questions from the floor?

210
00:29:12,119 --> 00:29:24,119
Well I don't know where the S4B hit but this is on the backside of the limb so I would assume that the S4B didn't hit there.

211
00:29:24,119 --> 00:29:26,119
And as well after that.

212
00:29:26,119 --> 00:29:29,119
Like a couple of days.

213
00:29:29,119 --> 00:29:30,119
Lunar days.

214
00:29:31,119 --> 00:29:35,119
Where did the S4B hit there?

215
00:29:35,119 --> 00:29:40,119
Oh it did about 150 kilometers north of station.

216
00:29:40,119 --> 00:29:41,119
What else?

217
00:29:47,119 --> 00:29:52,119
When you mentioned the intersting of Darden, what did you do out there?

218
00:29:52,119 --> 00:29:53,119
No.

219
00:29:54,119 --> 00:30:05,119
The time I was doing this I was looking out the window and I had darkened the cockpit in preparation for one of the low light level photographic exercises.

220
00:30:05,119 --> 00:30:09,119
And that's how I happened to be noticing that there was this distinct horizon which surprised me.

221
00:30:09,119 --> 00:30:13,119
And I just happened to be kind of puzzling over that at the time.

222
00:30:15,119 --> 00:30:16,119
Oh dear.

223
00:30:16,119 --> 00:30:17,119
Yeah I question.

224
00:30:17,119 --> 00:30:19,119
Sorry for being so serious.

225
00:30:20,119 --> 00:30:23,119
No.

226
00:30:23,119 --> 00:30:25,119
Now when your visors down.

227
00:30:25,119 --> 00:30:27,119
I never looked.

228
00:30:27,119 --> 00:30:29,119
What do I suppose to do that?

229
00:30:29,119 --> 00:30:40,119
I suspect from what we saw on EVA on the way home that the inner visor alone has sufficient attenuation to block out stars.

230
00:30:41,119 --> 00:30:47,119
But you could see them through the AOT and the lunar module and of course that has a light shield around it.

231
00:30:47,119 --> 00:31:01,119
On our last alignment even with the crescent earth and the AOT we could see arc in our real, really so good that we didn't have to roll up the window shades in the cockpit.

232
00:31:03,119 --> 00:31:08,119
So with the proper, if you look through a tube I'm sure you could see every star up there.

233
00:31:10,119 --> 00:31:15,119
The only thing we saw on the lunar surface was the earth and you had to, it was directly overhead.

234
00:31:15,119 --> 00:31:17,119
That was the only thing I saw in the sky.

235
00:31:17,119 --> 00:31:21,119
John, you're going through the site in the camera.

236
00:31:21,119 --> 00:31:24,119
Would you see anything that's like here?

237
00:31:24,119 --> 00:31:27,119
You see your helmet reflected.

238
00:31:27,119 --> 00:31:30,119
That's what you see. You have to raise your visor.

239
00:31:30,119 --> 00:31:31,119
Get a light.

240
00:31:31,119 --> 00:31:36,119
So you can get rid of all those reflections.

241
00:31:36,119 --> 00:31:43,119
Okay, next one is Active Size McExperiment, Dr. Covatch.

242
00:31:52,119 --> 00:31:57,119
Well we had several objectives on this experiment.

243
00:31:57,119 --> 00:32:04,119
I'd like to summarize these basic questions like how thick is the seismic regolith would be one question.

244
00:32:04,119 --> 00:32:09,119
What were the in situ physical properties of the lunar near surface material?

245
00:32:09,119 --> 00:32:18,119
Thirdly, are there any distinct seismic horizons and how do they correlate with our estimates to geological horizons?

246
00:32:18,119 --> 00:32:22,119
And finally, were there any regional differences in seismic velocities?

247
00:32:22,119 --> 00:32:27,119
IE, something characteristicly different between the mario and the islands?

248
00:32:27,119 --> 00:32:31,119
Well the deployment and the execution of the Thorpex Broin was outstanding.

249
00:32:31,119 --> 00:32:35,119
Our clearer and the background noise was sufficiently low.

250
00:32:35,119 --> 00:32:40,119
I mean got clean first breaks completely down the geophone line.

251
00:32:40,119 --> 00:32:42,119
I'm sorry about that first one.

252
00:32:42,119 --> 00:32:46,119
I was so really happy when that rascal worked that I stopped walking.

253
00:32:46,119 --> 00:32:51,119
I started walking to the next one.

254
00:32:51,119 --> 00:32:57,119
Well the record shows that for some reason you inadvertently didn't hold it in a charge position sufficiently long enough.

255
00:32:57,119 --> 00:33:00,119
That's the reason when you did it the second time.

256
00:33:00,119 --> 00:33:05,119
I thought I started walking too soon after the first one went off.

257
00:33:05,119 --> 00:33:09,119
The one that failed, yeah that was pure procedure there.

258
00:33:09,119 --> 00:33:12,119
Well if you walk too soon it didn't hurt us any.

259
00:33:12,119 --> 00:33:14,119
Didn't body?

260
00:33:14,119 --> 00:33:20,119
The data needs yet to be corrected for topographic effects.

261
00:33:20,119 --> 00:33:24,119
There are some severe undulations in the topography and we can see this in the data.

262
00:33:24,119 --> 00:33:30,119
But I can give you some first impressions of our results.

263
00:33:30,119 --> 00:33:36,119
Number one there is certainly no variability in the first arrival of velocities across the geophone array.

264
00:33:36,119 --> 00:33:43,119
And the parent velocity or the velocity is again very close to 100 meters per second.

265
00:33:43,119 --> 00:33:52,119
Which seems to be the magic number for the regolith at many different places now on the moon.

266
00:33:52,119 --> 00:34:00,119
IE out in the marion, now up here in the finally up in this highland site.

267
00:34:00,119 --> 00:34:05,119
There are no evidence of flows beneath this geophone line.

268
00:34:05,119 --> 00:34:11,119
I feel sufficiently confident we would recognize that.

269
00:34:11,119 --> 00:34:19,119
Now the fact that we didn't recognize any variability in the velocity we were able to say one more thing

270
00:34:19,119 --> 00:34:24,119
because we recorded the lamassent when we turned on the geophone line.

271
00:34:24,119 --> 00:34:30,119
And that was a position of some 140 meters away from our first geophone.

272
00:34:30,119 --> 00:34:33,119
And we did get a faster apparent velocity.

273
00:34:33,119 --> 00:34:38,119
And it's very close to the value measured for frah-marl for breccius.

274
00:34:38,119 --> 00:34:43,119
And so with this type of a number now, IE 2 to 300 meters per second underlying this regolith.

275
00:34:43,119 --> 00:34:47,119
We can put a thickness bound on the regolith at this site.

276
00:34:47,119 --> 00:34:50,119
And it is indeed very thick, at least 40 meters.

277
00:34:50,119 --> 00:34:57,119
And I'll be able to refine that number a little bit when we get the mortars fired.

278
00:34:57,119 --> 00:35:05,119
We also did turn on the ASE geophone array and recorded you know,

279
00:35:05,119 --> 00:35:08,119
you're over approaching the limiter at the end of EVA3.

280
00:35:08,119 --> 00:35:10,119
And we also got very interesting signals.

281
00:35:10,119 --> 00:35:17,119
And we hope to analyze these in an analogous way as Gary suggested.

282
00:35:17,119 --> 00:35:24,119
And that's about all I can say for the quick look of our data at this point.

283
00:35:24,119 --> 00:35:27,119
We do have the concern, of course.

284
00:35:27,119 --> 00:35:29,119
I do have the concern about the grenade box deployment.

285
00:35:29,119 --> 00:35:30,119
I'm sure I've asked you that.

286
00:35:30,119 --> 00:35:34,119
I haven't seen any of the pictures yet, so maybe the piece self-explained.

287
00:35:34,119 --> 00:35:36,119
Maybe you could reassure me that it's level.

288
00:35:36,119 --> 00:35:38,119
I guarantee you.

289
00:35:38,119 --> 00:35:42,119
In fact, that was probably the only level place we had around there.

290
00:35:42,119 --> 00:35:45,119
And I was really pleased to see when we got out the end of the,

291
00:35:45,119 --> 00:35:48,119
to where we could deploy it that would be level.

292
00:35:48,119 --> 00:35:50,119
It's really good.

293
00:35:50,119 --> 00:35:54,119
And I reported the, I don't remember what asthma's heading that we put it on.

294
00:35:54,119 --> 00:36:00,119
It was very close, seemed like it was 330 as opposed to 3333 that it should have been on.

295
00:36:00,119 --> 00:36:02,119
That's also top of my head.

296
00:36:02,119 --> 00:36:04,119
We had to go back and look, but I reported it.

297
00:36:05,119 --> 00:36:09,119
And I found out later that you could break that pin by pulling on the leg,

298
00:36:09,119 --> 00:36:14,119
but I certainly didn't know that, if somebody told me that doing the training

299
00:36:14,119 --> 00:36:17,119
why I had gone right over my head.

300
00:36:17,119 --> 00:36:22,119
But we do have three good legs in there, and I'll bet you that rascal can't get out of the ground

301
00:36:22,119 --> 00:36:23,119
because of the way it went in.

302
00:36:23,119 --> 00:36:25,119
It's sort of like pushing it into a quicksand.

303
00:36:25,119 --> 00:36:31,119
And once it gets in there, I define it by the way to get that mortar box back out of there.

304
00:36:32,119 --> 00:36:34,119
Because it really grabbed a hold of it.

305
00:36:37,119 --> 00:36:40,119
Well, again, I'd like to offer my thanks for an outstanding execution of the experiment

306
00:36:40,119 --> 00:36:42,119
and you couldn't ask anything better.

307
00:36:43,119 --> 00:36:44,119
Thank you.

308
00:36:44,119 --> 00:36:45,119
It was our pleasure.

309
00:36:45,119 --> 00:36:46,119
Boy, it really worked good.

310
00:36:46,119 --> 00:36:47,119
I was really pleased.

311
00:36:47,119 --> 00:36:48,119
Any questions?

312
00:36:48,119 --> 00:36:50,119
How did you define it?

313
00:36:50,119 --> 00:36:51,119
You had a record.

314
00:36:51,119 --> 00:36:52,119
Thank you.

315
00:36:52,119 --> 00:36:53,119
You said it.

316
00:36:53,119 --> 00:36:54,119
What was it like?

317
00:36:54,119 --> 00:36:55,119
What's that?

318
00:36:55,119 --> 00:36:56,119
You just need to speak.

319
00:36:56,119 --> 00:36:57,119
You said, please.

320
00:36:57,119 --> 00:36:58,119
Well, we defined the rate of it.

321
00:36:58,119 --> 00:37:00,119
I don't know how the biologists made it.

322
00:37:00,119 --> 00:37:01,119
I don't know how to create what you define.

323
00:37:01,119 --> 00:37:05,119
But we defined the material which apparently covered much of the lunar surface

324
00:37:05,119 --> 00:37:08,119
and has its characteristic velocity 100 meters per second.

325
00:37:08,119 --> 00:37:10,119
And what kind of that?

326
00:37:10,119 --> 00:37:15,119
Underneath this particular site, I mean, something that has velocities like fraught moral.

327
00:37:15,119 --> 00:37:16,119
Breastly.

328
00:37:17,119 --> 00:37:22,119
You said something about you were sure that there was no flow material underneath this.

329
00:37:22,119 --> 00:37:25,119
I guess I missed the conclusion.

330
00:37:25,119 --> 00:37:27,119
Well, we've done enough experiments on Earth.

331
00:37:27,119 --> 00:37:31,119
And I say that we've been able to recognize flows because of velocities are

332
00:37:31,119 --> 00:37:33,119
characteristically much higher.

333
00:37:33,119 --> 00:37:41,119
And if you want to argue that there may be very thin flows, i.e. thinner than our sampling wave length,

334
00:37:41,119 --> 00:37:43,119
which is like 2 to 3 meters, they could be there.

335
00:37:43,119 --> 00:37:48,119
But we certainly, on the average, did see any big sequence of high velocity flows.

336
00:37:48,119 --> 00:37:53,119
When you say high velocity, this 200 or 300 that you're talking about from the Ascent stage,

337
00:37:53,119 --> 00:37:55,119
that's not high enough for us.

338
00:37:56,119 --> 00:38:01,119
And it's every small crater that we looked into with exception, probably a buster crater.

339
00:38:01,119 --> 00:38:09,119
We never saw anything that looked like anything, but, I mean, it just looked like more of the same,

340
00:38:09,119 --> 00:38:13,119
it looked like, uh, regolith.

341
00:38:13,119 --> 00:38:16,119
I mean, you know, we never saw anything that looked like outcropper.

342
00:38:16,119 --> 00:38:18,119
And we were sure looking for it.

343
00:38:19,119 --> 00:38:21,119
This, too, is we have a meter of velocity.

344
00:38:21,119 --> 00:38:27,119
About the Lem Ascent, that was this breccia material that you see is underline the regolith, is that right?

345
00:38:27,119 --> 00:38:29,119
That's fine. First look at it.

346
00:38:29,119 --> 00:38:30,119
First look.

347
00:38:33,119 --> 00:38:35,119
What do you find in the water?

348
00:38:35,119 --> 00:38:36,119
Oh, that's another question.

349
00:38:36,119 --> 00:38:41,119
What's the latest word on water firing, do we have any idea of what kind of phenomena?

350
00:38:41,119 --> 00:38:47,119
Well, there's a meeting on Black Exact, you know, and I'm wondering what every question will be on May 23rd.

351
00:38:49,119 --> 00:38:50,119
Bastille things.

352
00:38:57,119 --> 00:38:58,119
And it's armed, too.

353
00:39:02,119 --> 00:39:08,119
Okay, our next, uh, next slide, because the Solar Wind Composition, Dr. Meister.

354
00:39:18,119 --> 00:39:23,119
Unfortunately, there is not much to tell about the Solar Wind Composition Experiment.

355
00:39:23,119 --> 00:39:28,119
The FOIL was transferred to Switzerland at the end of last weekend.

356
00:39:28,119 --> 00:39:31,119
We don't have any results yet, of course.

357
00:39:31,119 --> 00:39:39,119
The FOIL was deployed during the first EVA and retrieved at the end of the third EVA

358
00:39:39,119 --> 00:39:44,119
with a total exposure time of 45,000 and five minutes.

359
00:39:45,119 --> 00:39:53,119
That's some three hours longer than the record of the previous missions, which was about 52 hours on Apollo 15.

360
00:39:55,119 --> 00:40:12,119
The main difference between the FOIL of Apollo 16 and the ones of the previous missions is that some pieces of platinum foil have been attached to the previous design, which was composed of a pure aluminum foil.

361
00:40:12,119 --> 00:40:23,119
These platinum foil pieces can be cleaned by a fluoridic acid, which allows to remove all the possible lunar dust contamination.

362
00:40:23,119 --> 00:40:41,119
This technique has been tested in the lab on bombarded foils and showed that you can remove essentially all the lunar dust contamination without losing any measurable amount of trapped rare gas ions.

363
00:40:41,119 --> 00:40:47,119
This is a very rare gas atom of Solar Wind origin.

364
00:40:47,119 --> 00:41:04,119
This technique should allow us to determine the isotopic composition of the rare gas elements of Solar Wind origin up to the mass of possibly Krypton.

365
00:41:04,119 --> 00:41:15,119
The first visual inspection of the foil here at MSC showed that the foil is crimpled, but essentially free of lunar dust.

366
00:41:15,119 --> 00:41:20,119
That's of course only a visual observation.

367
00:41:20,119 --> 00:41:24,119
We don't know how the foil looks like on the microscope.

368
00:41:25,119 --> 00:41:31,119
I would like to thank the crew for the proper deployment and retrieval of the foil.

369
00:41:31,119 --> 00:41:37,119
We are very pleased with what the foil looks like. Thank you very much.

370
00:41:37,119 --> 00:41:39,119
I can't miss when it's the only world's sun here.

371
00:41:39,119 --> 00:41:42,119
Point this at sun.

372
00:41:42,119 --> 00:41:52,119
The thing didn't roll up like I thought it was going to, and I'm sorry I had to crinkle it, but it was so big and had to squeeze it down and get it into the bag.

373
00:41:52,119 --> 00:41:55,119
It ripped once too. I guess you saw that.

374
00:41:55,119 --> 00:41:59,119
That's only a problem of aesthetics. It doesn't hurt it.

375
00:41:59,119 --> 00:42:02,119
It's okay, good. I didn't thank you, Dad.

376
00:42:02,119 --> 00:42:04,119
God.

377
00:42:04,119 --> 00:42:11,119
The local magnetic field is staring off the floor over there and the problem is a lot of bacteria.

378
00:42:11,119 --> 00:42:23,119
We don't know yet that I think that we have a discrimination between the lighter and heavier elements in the solar window.

379
00:42:23,119 --> 00:42:34,119
We have to check that maybe that there's a dependence on the height over the lunar surface of the composition between the heavier and lighter elements.

380
00:42:34,119 --> 00:42:37,119
But we have to check that first and see.

381
00:42:37,119 --> 00:42:41,119
The lighter particles, the more the light is important.

382
00:42:41,119 --> 00:42:47,119
It also would be deflected much more than the heavier ones.

383
00:42:47,119 --> 00:42:55,119
Can you see those, I don't know, this probably a stupid question, but these cosmic particles that cause the light flashes.

384
00:42:55,119 --> 00:42:59,119
I was seeing them on the lunar surface during the sleep periods.

385
00:42:59,119 --> 00:43:02,119
Are those things registered on your experiment?

386
00:43:02,119 --> 00:43:08,119
No, they have higher energies and they go through the foil.

387
00:43:08,119 --> 00:43:11,119
Huh?

388
00:43:11,119 --> 00:43:17,119
What are these blusers thinking?

389
00:43:17,119 --> 00:43:24,119
Can you tell me a difference in the materials that you think the time is a 20 times, and you brought the bacteria in your film and you might have a 20.

390
00:43:24,119 --> 00:43:27,119
No.

391
00:43:28,119 --> 00:43:30,119
No difference there.

392
00:43:30,119 --> 00:43:34,119
Looking at it one time, I thought I saw some white streaks on it.

393
00:43:34,119 --> 00:43:37,119
It might have been just the way the sun was.

394
00:43:37,119 --> 00:43:42,119
It might have been those platinum strips that I never noticed when I had been placed.

395
00:43:42,119 --> 00:43:44,119
I really don't know.

396
00:43:44,119 --> 00:43:50,119
It just looked like I had a couple of randomly oriented streaks on it to me from the Wint Lim, Wendell.

397
00:43:50,119 --> 00:44:02,119
When we rolled it back up again, instead of rolling straight up, it rolled out in a big long thing and I had to redo it again and when that happened I ripped it and had to crunch it now.

398
00:44:02,119 --> 00:44:10,119
We don't see any difference between the foil we sent up and the foil that came down except of some lunar dust on it.

399
00:44:10,119 --> 00:44:13,119
Nothing else.

400
00:44:13,119 --> 00:44:16,119
I think it was a cruel question.

401
00:44:16,119 --> 00:44:19,119
Do you have an idea how the foil was oriented?

402
00:44:19,119 --> 00:44:22,119
Was it the central vertical to the port?

403
00:44:22,119 --> 00:44:23,119
Yes.

404
00:44:23,119 --> 00:44:30,119
Mine mean along the gravitational force lines or was it reclined or incline?

405
00:44:30,119 --> 00:44:34,119
It's hard to tell it from the evidence.

406
00:44:34,119 --> 00:44:39,119
I think I put it in almost parallel with the gravity vector.

407
00:44:39,119 --> 00:44:46,119
I want to slow it a little but if I recall it was it's aligned almost vertically.

408
00:44:46,119 --> 00:44:48,119
Thank you very much.

409
00:44:48,119 --> 00:44:51,119
Thank you.

410
00:44:51,119 --> 00:44:58,119
The next subject will be the cosmic-graded tector, Dr. Bob Pleasher.

411
00:44:58,119 --> 00:45:01,119
See here.

412
00:45:01,119 --> 00:45:04,119
Oh, okay.

413
00:45:04,119 --> 00:45:09,119
I'll see you later.

414
00:45:09,119 --> 00:45:11,119
The PI's could be here this morning.

415
00:45:11,119 --> 00:45:16,119
They're busily at home studying the data that they got back.

416
00:45:16,119 --> 00:45:22,119
I have some words from them that I'll pass along as to what they think they'll be able to see.

417
00:45:22,119 --> 00:45:26,119
They're very excited about the possibilities they have.

418
00:45:26,119 --> 00:45:33,119
Early in the mission there was a solar particle event that occurred which will enhance their data very significantly.

419
00:45:33,119 --> 00:45:45,119
They think they'll have the opportunity to see particles from the Sun that on an ordinary mission they would have never had the opportunity to see.

420
00:45:45,119 --> 00:45:51,119
When they got the experiment back panel one did have considerable dust on it.

421
00:45:51,119 --> 00:46:03,119
This from the best we can tell without any analysis came from the landing itself from the blast up from the DPS.

422
00:46:03,119 --> 00:46:09,119
Panel one was hot in the taking the panels apart.

423
00:46:09,119 --> 00:46:20,119
Panels two and three were cooler and panel four was of the same order of temperatures as panel two and three.

424
00:46:20,119 --> 00:46:28,119
Cosmic grade data itself in the plastics appears to be degraded somewhat because of the temperature.

425
00:46:28,119 --> 00:46:35,119
But they're very hopeful that a great part of the data will be retrievable.

426
00:46:35,119 --> 00:46:49,119
At the first look on panel two is Dr. Pleasher says that the number of particles they see on the plastics indeed are a great deal higher than they would have normally anticipated.

427
00:46:49,119 --> 00:46:59,119
Indicating the effects of the solar particle event and they really haven't in detail etched the plastics or analyzed them they're just beginning to do that.

428
00:46:59,119 --> 00:47:02,119
They think they are usable.

429
00:47:02,119 --> 00:47:18,119
Yes the plastic is a surprise because we had some linked discussions about this pre-flight and I can never understand how we're going to fly this rascal to the moon and get it there with us with these long periods of attitude hole that we're going into where it might see plus 250 all the time.

430
00:47:18,119 --> 00:47:35,119
Of course I'm sure those three revs in lunar orbit prior landing didn't do any good either because we were oriented many times so that we're facing with the maintained communications we had the sun shining on that rascal all the way around.

431
00:47:35,119 --> 00:47:49,119
I really think those 140 temperatures that we saw in the panels if you go back and look at it thermally you're going to find out they had to be there long before we ever got the thing on the ground.

432
00:47:49,119 --> 00:47:56,119
I was really concerned about that as to why we put some kind of shield in orbit but it was too late I guess to do this.

433
00:47:56,119 --> 00:48:08,119
Well the thermal design was such that it could sit I believe in direct sunlight almost indefinitely without indeggredation it's the hour heating off the lunar surface that really cooks from the thermal people say.

434
00:48:08,119 --> 00:48:18,119
I think and it's hard to say and we did see the early picture did show that the temple labels had already changed early at the beginning of the EVA.

435
00:48:18,119 --> 00:48:21,119
They were black first time in the world.

436
00:48:21,119 --> 00:48:36,119
I guess is the 15 hours the thermal analysis says if there's like 15% dust on the panel after 20 degrees of sun angle or so you will sort of exceed the 140 degrees on the frame.

437
00:48:36,119 --> 00:48:45,119
It appeared that there was probably 50 or 60% dust on the lower part of the panel or maybe even higher than that and it's been about 15 hours on the surface.

438
00:48:45,119 --> 00:48:55,119
So it may have just turned out to be a number of problems that probably ones that could not be avoided under the circumstances that caused that lower panel over heat.

439
00:48:55,119 --> 00:49:01,119
It was the hottest and the next panel was about 20 degrees cooler the best we can tell in the panel.

440
00:49:01,119 --> 00:49:10,119
Third panel up was 10 degrees cooler than the second panel so it seemed to be a dust problem but it doesn't seem to have hurt the data too much.

441
00:49:10,119 --> 00:49:20,119
The panel 4 was the one which we were afraid wasn't going to be activated because of the anomaly on the red line.

442
00:49:20,119 --> 00:49:27,119
But after they have taken the panel apart apparently every portion of the experiment was activated to some degree or another.

443
00:49:27,119 --> 00:49:36,119
The neutron portion was partially deployed and they think they will get some data from it is not as much data statistically as they wish they had.

444
00:49:36,119 --> 00:49:48,119
But every portion of panel 4 does look like it will provide some useful data and they have a lot higher hopes now than they did when they first saw the gear.

445
00:49:48,119 --> 00:50:00,119
Apparently the problem and we haven't sent the hardware back to the manufacturer for analysis but apparently was a malfunction in the assembly and caused that thing to jam.

446
00:50:00,119 --> 00:50:07,119
Well we could have pulled if I didn't know about it at the time we got that pair of pliers out there and pulled harder.

447
00:50:07,119 --> 00:50:10,119
The investigators opinion wise it would have done well good.

448
00:50:10,119 --> 00:50:18,119
It wouldn't have very severely jammed and he doesn't think any additional effort would have freed it. It was jammed pretty bad.

449
00:50:18,119 --> 00:50:27,119
But I think in all they are very excited about the data and I think they are very optimistic now that they will get considerable amount of data from it.

450
00:50:27,119 --> 00:50:49,119
The other thing is that on panel 4 is those experiments which are activated by pulling the cord around a small fraction of the total part of the panel 4.

451
00:50:49,119 --> 00:50:57,119
That's true. We still have a lot of good data in the system. The data is in the dam that has never occurred.

452
00:50:57,119 --> 00:51:01,119
That's for all practical purposes.

453
00:51:01,119 --> 00:51:18,119
I don't think we, in fact I'm sure you may find a fingerprint on there but if there is we really are careful to get it out of there and once we got it loose we have to use your 10-11 carer and fold it up.

454
00:51:18,119 --> 00:51:23,119
I don't think there is any proof fingerprints on the panel surfaces.

455
00:51:23,119 --> 00:51:29,119
That's correct. We looked at it very carefully and it was except for the bottom part of panel 1 that you could see.

456
00:51:29,119 --> 00:51:37,119
It was a spray pattern. It was very clean and the PIs were very pleased about that.

457
00:51:37,119 --> 00:51:41,119
The cell of the part of the panel.

458
00:51:41,119 --> 00:51:49,119
Yes, it started on about, I believe, Monday which was the day after launch and went through about Wednesday.

459
00:51:49,119 --> 00:51:57,119
It was about a two or three day type event. I think the peak must have been about Tuesday.

460
00:51:57,119 --> 00:52:04,119
There are some satellite data available and I don't have that on hand.

461
00:52:04,119 --> 00:52:16,119
It was a small event but for this solar cycle it was very surprising that it happened at all during the mission that the habit during the portion when the cosmic ray was deployed or available to the encampter.

462
00:52:16,119 --> 00:52:22,119
The probability of that is very small so it's a very gratifying thing to occur.

463
00:52:22,119 --> 00:52:34,119
I'm curious about the dustbin. Did you guys observe any dust on the thing or any other part of the limb at that level?

464
00:52:34,119 --> 00:52:41,119
It's always been our question. If it does, is it sent out in a pretty thin layer?

465
00:52:41,119 --> 00:52:49,119
I'm sure it's sent out in a thin layer but with all those frontal blocks around there it's a possibility some of it could come back at you.

466
00:52:49,119 --> 00:52:59,119
It was extremely hard to see and when we photographed it the lights are not similar to the sun. Probably much less than intensity but yet the photographic lights did wash out.

467
00:52:59,119 --> 00:53:13,119
It's a very pale kind of dust but it's very predominant and it came up from the corner day even in a pattern that you would expect it to be blown and there were some black streaks in there that are prepared to be melted something or other on it.

468
00:53:13,119 --> 00:53:25,119
I think they are going to attempt to chemically analyze the material and try to find out what it is.

469
00:53:25,119 --> 00:53:29,119
The first panel must be about chest height.

470
00:53:29,119 --> 00:53:34,119
Any other questions?

471
00:53:34,119 --> 00:53:43,119
The frame of that thing was hot. It was the only thing I felt through my gloves.

472
00:53:43,119 --> 00:53:54,119
It was jamming and John tried to pull it out and I was holding the frame and I started feeling it through my gloves.

473
00:53:54,119 --> 00:54:01,119
It was jamming at the base right at the bottom part.

474
00:54:01,119 --> 00:54:09,119
There was something that broke free right at the base and then it just came out like it had grease on it.

475
00:54:09,119 --> 00:54:13,119
Maybe we spilled some orange juice over it.

476
00:54:13,119 --> 00:54:22,119
No way. That's the only thing we didn't spill orange juice on.

477
00:54:22,119 --> 00:54:25,119
It's not that you didn't try it.

478
00:54:25,119 --> 00:54:29,119
That's a good cement you guys. You ought to start thinking about that.

479
00:54:29,119 --> 00:54:33,119
Suppose that stuff to vacuum more.

480
00:54:33,119 --> 00:54:42,119
Okay, our next experiment was the FAR UV camera Dr. Page.

481
00:54:42,119 --> 00:54:45,119
I'll put a banner in one of the yellow.

482
00:54:45,119 --> 00:54:47,119
Just see it all in a complete goal.

483
00:54:47,119 --> 00:55:00,119
The purposes of this experiment were to obtain photographs and the viral profile of the geocoroner in the upper atmosphere of the earth.

484
00:55:00,119 --> 00:55:06,119
I should have said these photographs of course, in the food spectra as well.

485
00:55:06,119 --> 00:55:13,119
Before wind clouds possibly, iter stellar hydrogen.

486
00:55:13,119 --> 00:55:18,119
Colors of stars and the viral profile and possibly intergalactic hydrogen.

487
00:55:18,119 --> 00:55:23,119
We had a lot of troubles I guess John well knows.

488
00:55:23,119 --> 00:55:35,119
Before launch the difficulty was to keep the camera dry because it's optically sensitive surface would immediately run away if it got damp.

489
00:55:35,119 --> 00:55:48,119
This was accomplished with a bag that caused Captain Young a little bit of trouble in practices in advance but apparently worked alright on the lunar surface.

490
00:55:48,119 --> 00:55:50,119
That's great.

491
00:55:50,119 --> 00:55:55,119
The second difficulty was getting through the Van Allen belts without fogging our film.

492
00:55:55,119 --> 00:56:04,119
I'll show you in a moment that we did that alright with a rather small amount of shielding around the film cassette.

493
00:56:05,119 --> 00:56:10,119
Then we had some difficulty with the lens being in the way.

494
00:56:10,119 --> 00:56:20,119
This came about because of the delay and touched down high sun angle and the necessity to keep the camera close to the lens so that it would be in the shadow.

495
00:56:20,119 --> 00:56:27,119
With its gold surface it would have heated up very rapidly but it had been out in the full sunlight.

496
00:56:28,119 --> 00:56:45,119
The accomplishments that I will show you in a moment on the screen include 92 photographs in the laminar alpha imagery and 53 spectra.

497
00:56:45,119 --> 00:56:50,119
Some of them extending from 500 angstroms to 1550 angstroms.

498
00:56:50,119 --> 00:56:57,119
I think the farthest into the ultraviolet anybody has ever taken astronomical pictures.

499
00:56:57,119 --> 00:57:08,119
We may get evidence of gases in the lunar atmosphere from several of our pointings which were low across the lunar horizon.

500
00:57:08,119 --> 00:57:18,119
If anything were coming out like geysers of water or whatever it is we will certainly pick it up.

501
00:57:18,119 --> 00:57:32,119
The data on these photographs are extremely numerous and it will take us an estimated six months to a year to get them all out which will be done with the big computer here at the MSC.

502
00:57:32,119 --> 00:57:42,119
Dr. George Brothers who is the PI and who designed the camera happened to be free today to work on an Arabian flight and is here.

503
00:57:42,119 --> 00:57:47,119
We will certainly make comments whenever he sees something to comment on the photographs.

504
00:57:47,119 --> 00:57:56,119
We have the first slide. I might say that I got into trouble with the American Photographer's Union in thanking the prints of these because I am not a member of that unit.

505
00:57:56,119 --> 00:58:00,119
They tried to throw me out of the darkening pool over here.

506
00:58:00,119 --> 00:58:09,119
This is probably one of the most dramatic pictures of the years that shows a rural belt on the dark side.

507
00:58:09,119 --> 00:58:23,119
If you are looking at the years with the sun off to your right, the south pole of the earth is down and that funny lip-like thing sticking off to the left of the bond is aurora we think around the South magnetic pole.

508
00:58:23,119 --> 00:58:34,119
The most striking thing is the next lip up which on the original you can see better than on this slide goes around the full back side of the earth.

509
00:58:34,119 --> 00:58:45,119
It is called the equatorial auroral belt and this appears back of the dark side in the upper left corner.

510
00:58:45,119 --> 00:58:55,119
The third lip is another belt. It looks at first as if that was just all one but there are two separate belts there and was quite unexpected.

511
00:58:55,119 --> 00:59:00,119
What is the condition of the earth's sacks of size?

512
00:59:00,119 --> 00:59:02,119
It is 8000 miles cross.

513
00:59:02,119 --> 00:59:09,119
You will.

514
00:59:09,119 --> 00:59:14,119
There is some halation here and I guess I am not too sure and perhaps George knows.

515
00:59:14,119 --> 00:59:20,119
This is a special Eastman NTB III emulsion, very very thin.

516
00:59:20,119 --> 00:59:27,119
The exposure was made with electrons not with light. It is an electronic camera.

517
00:59:27,119 --> 00:59:32,119
The dimension works out right. You cannot see it too well on this print.

518
00:59:32,119 --> 00:59:39,119
There is a ring or a limit to the field which on the originals is 30 millimeters across.

519
00:59:39,119 --> 00:59:45,119
It is 20 degrees in the sky and the earth is 2 degrees and it checks out.

520
00:59:46,119 --> 00:59:52,119
The dimension you see there is 2 degrees across the full diameter of the earth.

521
00:59:52,119 --> 00:59:56,119
You see this as the equatorial or a little belt.

522
00:59:56,119 --> 00:59:59,119
I think what John says is that one study is third line for the bottom.

523
00:59:59,119 --> 01:00:01,119
He says the back side and you see no.

524
01:00:01,119 --> 01:00:03,119
No, you cannot see through the earth.

525
01:00:03,119 --> 01:00:06,119
That is why I ask you if you see the earth and cover it.

526
01:00:06,119 --> 01:00:14,119
No, the geometry is such that that is probably inclined 30 degrees to the magnetic equator and is an unexpected auroral belt.

527
01:00:14,119 --> 01:00:21,119
It will take a little more figuring to figure this out.

528
01:00:21,119 --> 01:00:26,119
As I just said, my guess looking at the picture hasn't been measured accurately.

529
01:00:26,119 --> 01:00:29,119
It is 30 degrees north.

530
01:00:29,119 --> 01:00:40,119
You will notice on these pictures that they are overprinted.

531
01:00:40,119 --> 01:00:43,119
That is because I am not a member of the photographer's union.

532
01:00:43,119 --> 01:00:47,119
The originals have a good deal more on them.

533
01:00:47,119 --> 01:00:52,119
This picture was taken excluding hydrogen light, lemon alpha.

534
01:00:52,119 --> 01:01:00,119
We have two filters on the camera and this one is taken in light between the wavelengths of 12, 30 and 15, 50 angstroms.

535
01:01:00,119 --> 01:01:03,119
Now the next slide.

536
01:01:03,119 --> 01:01:08,119
Is that all the earth or is that twice point here?

537
01:01:08,119 --> 01:01:10,119
No, it is the earth.

538
01:01:10,119 --> 01:01:15,119
Is that twice the image?

539
01:01:15,119 --> 01:01:17,119
No, no.

540
01:01:17,119 --> 01:01:24,119
As I said, the little halation which makes it a little bigger than it ought to be.

541
01:01:24,119 --> 01:01:31,119
Now this one, it is exactly the same view, it was taken after John so accurately pointed the camera at the earth.

542
01:01:31,119 --> 01:01:36,119
The earth is in the middle there and if you look real hard you can see the dark side of it off to your left.

543
01:01:36,119 --> 01:01:38,119
This is the geocorona.

544
01:01:38,119 --> 01:01:42,119
The streaks are an instrumental matter.

545
01:01:42,119 --> 01:01:54,119
Actually we have a barrier membrane that George put very close in front of the film to keep a visible light from getting in there.

546
01:01:54,119 --> 01:01:57,119
And the barrier membrane wasn't quite uniform and that is where the streaks come from.

547
01:01:57,119 --> 01:02:02,119
The circular thing on the right is an overlap, another defect.

548
01:02:02,119 --> 01:02:08,119
The little motor that advanced the film between exposures didn't pull it quite far enough for this one.

549
01:02:08,119 --> 01:02:15,119
And those dust specks I guess are my piped it back on the slide.

550
01:02:15,119 --> 01:02:22,119
That rastly thing was moving.

551
01:02:22,119 --> 01:02:26,119
At first it wasn't moving, the wheels weren't going as far as they did before the end.

552
01:02:26,119 --> 01:02:30,119
Now we have a complete transcript of everything you said about it.

553
01:02:30,119 --> 01:02:42,119
And in looking at the film which I have done in great detail, you can see the most serious defect in that film advance was during your short exposures on the earth.

554
01:02:42,119 --> 01:02:45,119
John everywhere else it worked fine.

555
01:02:45,119 --> 01:02:55,119
And I have an idea that pushing the button so frequently sort of confused the motor and it didn't turn as far as it should have.

556
01:02:55,119 --> 01:03:03,119
Well in any case you'll notice that the shape of the geocorona is predicted by Dr. Meyer at the Naval Research Lab.

557
01:03:03,119 --> 01:03:08,119
It's got a dimple in the back, down the sun, the sun is still to the right here.

558
01:03:08,119 --> 01:03:15,119
And our other photographs show that it extends at least twice as far as you see here off to the right.

559
01:03:15,119 --> 01:03:18,119
The print of course can be printed dark or light.

560
01:03:18,119 --> 01:03:27,119
And if I printed this one lighter I'd have got the background all over the whole slide and you wouldn't have been able to see it's pretty a picture of this.

561
01:03:27,119 --> 01:03:32,119
Now the next slide shows the one further to the right.

562
01:03:32,119 --> 01:03:36,119
The sun is still to your right. The earth now is off the edge of the picture to the left.

563
01:03:36,119 --> 01:03:44,119
This was one of the sequence taken through the night between EVAs 2 and 3.

564
01:03:44,119 --> 01:03:58,119
You see a star background here and again the geocorona, those streaks which are not real, extending actually right across this frame if you print the thing lighter.

565
01:03:58,119 --> 01:04:09,119
Now the next slide shows the two of these combined and I printed a lot darker and I guess it's not as artistic an effort as I had hoped.

566
01:04:09,119 --> 01:04:19,119
The geocorona produces is hydrogen in 1216 angstroms line of alpha.

567
01:04:19,119 --> 01:04:24,119
And the next slide shows the spectrum actually taken on that first slide.

568
01:04:24,119 --> 01:04:33,119
The spectrum is dispersion is vertical and that white band across horizontally is line of alpha.

569
01:04:33,119 --> 01:04:50,119
You see how strong it is. The earth is in the middle of this picture and the spectrum of the upper atmosphere is spread out on that vertical line from far ultraviolet down at the bottom to nearer ultraviolet up at the top.

570
01:04:50,119 --> 01:05:02,119
Bright line just above line of alpha is 1304 which is oxygen line and George do you want to describe this one more detail?

571
01:05:02,119 --> 01:05:12,119
We've so far only made a very crude analysis of the spectrum by comparison with the laboratory spectrum made in the preflight calibrations.

572
01:05:12,119 --> 01:05:28,119
However we have tentatively identified the 584 line of helium, the 834 line of atomic ionized oxygen, the 1026 line line beta of hydrogen.

573
01:05:28,119 --> 01:05:35,119
These three lines are the first spectral measurements in the earth's upper atmosphere.

574
01:05:35,119 --> 01:05:52,119
All previous measurements have been limited to wavelength's long word of 1100 angstroms which we also cover and which includes the line of alpha line in 1216, the 1304 and 1356 lines of atomic oxygen.

575
01:05:52,119 --> 01:06:01,119
And the Lyman-Herk-Burge-Hopfield bands of molecular nitrogen between 1216, 100 angstroms.

576
01:06:01,119 --> 01:06:07,119
The Lyman alpha line of course is by far the strongest emission that we have seen in any of our spectra.

577
01:06:07,119 --> 01:06:13,119
And it's the only one that we have conclusively identified in any of the spectra that do not include the earth.

578
01:06:13,119 --> 01:06:37,119
However by comparison of spectra taken with and without our lithium fluoride corrector plate which cuts off at 1050 angstroms we will be able to determine whether we see a general background in the 584 line of helium and the 1026 line of atomic oxygen and hydrogen as we expect though there will be much weaker than the Lyman alpha line.

579
01:06:37,119 --> 01:06:40,119
You got that other spectrum.

580
01:06:40,119 --> 01:06:42,119
Okay, you know those can you hold on a minute.

581
01:06:42,119 --> 01:06:47,119
I think the order he's got in has the Magellanic Cloud and we're probably taking too much time.

582
01:06:47,119 --> 01:06:50,119
We have the next line.

583
01:06:50,119 --> 01:06:54,119
Well that's it.

584
01:06:54,119 --> 01:06:57,119
This is without the corrector plate.

585
01:06:57,119 --> 01:07:00,119
You notice the Lyman alpha here in broder.

586
01:07:00,119 --> 01:07:08,119
The definition is poor but as Georgia just saying we get lines further down in the ultraviolet.

587
01:07:08,119 --> 01:07:11,119
Spectra taken without the corrector plate with it.

588
01:07:11,119 --> 01:07:15,119
And you see here too these other lines are not uniform.

589
01:07:15,119 --> 01:07:20,119
This is a spectrum that was obtained with the earth off the edge here.

590
01:07:20,119 --> 01:07:25,119
So it shows that the geochronicals right across this slide as I said last time.

591
01:07:25,119 --> 01:07:28,119
So that's 100,000 miles.

592
01:07:28,119 --> 01:07:35,119
Other lines here show that either other materials in the geochrona or beyond the geochrona.

593
01:07:35,119 --> 01:07:40,119
I guess I'm going to take a little while to figure out which of which.

594
01:07:40,119 --> 01:07:43,119
Go ahead.

595
01:07:43,119 --> 01:07:48,119
The next two slides quickly show the last one.

596
01:07:48,119 --> 01:07:54,119
The Magellanic Clouds which are both John was worried about what Bell and the Sea meant.

597
01:07:54,119 --> 01:07:59,119
The Magellanic Clouds that's the initial what the initials refer to.

598
01:07:59,119 --> 01:08:03,119
The picture on the left is with hydrogen with planet alpha.

599
01:08:03,119 --> 01:08:06,119
The picture on the right is without.

600
01:08:06,119 --> 01:08:13,119
In this far over out of region all that you are seeing here are the very hot blue stars.

601
01:08:13,119 --> 01:08:17,119
Over here you see the clouds of hydrogen gas.

602
01:08:17,119 --> 01:08:20,119
So the difference between these two photographs is hydrogen.

603
01:08:20,119 --> 01:08:22,119
The regular.

604
01:08:22,119 --> 01:08:25,119
The Magellanic Clouds are nearby galaxies.

605
01:08:25,119 --> 01:08:31,119
So we have a galaxy with all the stars and then we need to spread out in front of this study.

606
01:08:31,119 --> 01:08:36,119
Carl and I was with me special studies in these Magellanic Clouds.

607
01:08:36,119 --> 01:08:41,119
And it's very much interested in all the already has copies of these photographs.

608
01:08:41,119 --> 01:08:46,119
You notice that the hydrogen is not just from the Magellanic Clouds.

609
01:08:46,119 --> 01:08:53,119
The stuff up here is out in the open sky and just what caused that background.

610
01:08:53,119 --> 01:08:57,119
Is there any other slide?

611
01:08:57,119 --> 01:09:01,119
That's the last one.

612
01:09:01,119 --> 01:09:05,119
We had a couple of questions for John.

613
01:09:05,119 --> 01:09:07,119
One was that sticking which had us worried.

614
01:09:07,119 --> 01:09:11,119
You talked about the the instrument.

615
01:09:11,119 --> 01:09:13,119
Mayfly on the Apollo 17 Rock Road.

616
01:09:13,119 --> 01:09:15,119
Very interested in it.

617
01:09:15,119 --> 01:09:17,119
Yeah.

618
01:09:17,119 --> 01:09:22,119
And so what was what was the sticking did it continue right through?

619
01:09:22,119 --> 01:09:24,119
You didn't mention it in the A3.

620
01:09:24,119 --> 01:09:27,119
I got it got worse all along.

621
01:09:27,119 --> 01:09:34,119
I just got the feeling there was some kind of hang up between in.

622
01:09:34,119 --> 01:09:46,119
Possibly long term vacuum exposure or something to the operation of the way it was working in Asmuth.

623
01:09:46,119 --> 01:09:52,119
And I never was able to never able to do it.

624
01:09:52,119 --> 01:09:54,119
No, it never got better.

625
01:09:54,119 --> 01:09:57,119
In fact, this is the longer it sat there.

626
01:09:57,119 --> 01:09:59,119
Maybe the cold.

627
01:09:59,119 --> 01:10:02,119
It just seemed to get stickier and stickier.

628
01:10:02,119 --> 01:10:07,119
And every time I had to, every time I got to a new setting in Asmuth,

629
01:10:07,119 --> 01:10:11,119
it completely destroyed the level.

630
01:10:11,119 --> 01:10:21,119
And we were unfortunate that we were on that slope right there under the footpath of the limb.

631
01:10:21,119 --> 01:10:24,119
So I had to go back and re-level it every time.

632
01:10:24,119 --> 01:10:35,119
And we were really working at the limits of the level of ability of the machinery, I think there.

633
01:10:35,119 --> 01:10:38,119
You see there didn't make much difference.

634
01:10:38,119 --> 01:10:41,119
Is that Magi-I-Cloch should have been out in the middle of the video?

635
01:10:41,119 --> 01:10:42,119
I know.

636
01:10:42,119 --> 01:10:45,119
You were off by that much because...

637
01:10:45,119 --> 01:10:52,119
But if we were on a level slope, there would have been no problem in getting the bubble right in the middle every time.

638
01:10:52,119 --> 01:10:57,119
Asmuth had worked easily, it would have remained level.

639
01:10:57,119 --> 01:10:59,119
But I sure don't know what it was.

640
01:10:59,119 --> 01:11:02,119
It couldn't have been dust that got in there.

641
01:11:02,119 --> 01:11:06,119
No, I don't think we had any...

642
01:11:06,119 --> 01:11:14,119
In fact, I'm sure we didn't have any dust on the legs up that far.

643
01:11:14,119 --> 01:11:18,119
The film is that you brought back and buried all the dust on.

644
01:11:18,119 --> 01:11:20,119
If I could put it in the new...

645
01:11:20,119 --> 01:11:24,119
Well, if it got dust on it, it got it inside the limb.

646
01:11:24,119 --> 01:11:27,119
There was plenty in there once we got into zero gravity.

647
01:11:27,119 --> 01:11:30,119
Although I don't know how to crawl through two bags.

648
01:11:30,119 --> 01:11:32,119
That's why I was quite surprised.

649
01:11:32,119 --> 01:11:36,119
I don't know if I were disappointed because we were going to collect a little bit of dust on it.

650
01:11:36,119 --> 01:11:39,119
Any question in the court?

651
01:11:39,119 --> 01:11:44,119
And I'm sure it got some dust on it when I removed it, though.

652
01:11:44,119 --> 01:11:50,119
I got a little, a very small amount, which I'm legally keeping in my business.

653
01:11:50,119 --> 01:11:54,119
Don't tell anybody the FBI will be around to see you.

654
01:11:54,119 --> 01:11:58,119
Did you see evidence of the fact that you were shooting or all shot?

655
01:11:58,119 --> 01:12:03,119
Some far we have not seen any discontent ody in the up sun,

656
01:12:03,119 --> 01:12:07,119
due to the corona, which would be the corona, kidney, kidney, and so on.

657
01:12:07,119 --> 01:12:11,119
It just sort of triples off the weight, and you go somewhere from the earth,

658
01:12:11,119 --> 01:12:13,119
and there's no sharp drop.

659
01:12:13,119 --> 01:12:16,119
We're really not as far as the shock.

660
01:12:16,119 --> 01:12:19,119
I can't remember the radiation.

661
01:12:19,119 --> 01:12:24,119
Is it only 10, 12?

662
01:12:24,119 --> 01:12:27,119
No.

663
01:12:27,119 --> 01:12:31,119
Okay, any more questions?

664
01:12:31,119 --> 01:12:36,119
Next subject is the Lunar Geology Investigation, Dr. Mulvard.

665
01:12:43,119 --> 01:12:46,119
Okay.

666
01:12:52,119 --> 01:12:55,119
For the benefit of the astrologer in the crowd,

667
01:12:55,119 --> 01:13:03,119
there's been very little evidence for water, and none so far for geysers.

668
01:13:03,119 --> 01:13:07,119
Our experiment may not be as far reaching as there,

669
01:13:07,119 --> 01:13:12,119
but on the other hand, I think we've made a large step toward understanding the history of the moon,

670
01:13:12,119 --> 01:13:15,119
and therefore the earth, and therefore the solar system.

671
01:13:15,119 --> 01:13:20,119
And if you guys can find any more, we're out there with you.

672
01:13:20,119 --> 01:13:25,119
So far, we've completed the mission itself,

673
01:13:25,119 --> 01:13:30,119
and all major objectives for the pre-plan traverses were reached,

674
01:13:30,119 --> 01:13:34,119
and we're sampled, and we're described, and photographed.

675
01:13:34,119 --> 01:13:37,119
As far as we can tell, with our quick look at the photographs,

676
01:13:37,119 --> 01:13:40,119
all of these were done well.

677
01:13:40,119 --> 01:13:46,119
We've produced a so-called greenback at the end of the mission operations itself,

678
01:13:46,119 --> 01:13:48,119
which was a summary as ever.

679
01:13:48,119 --> 01:13:54,119
Knowledge at that time that was based on crew observations, TV, and the pre-mission data.

680
01:13:54,119 --> 01:13:57,119
Included in that thing are station sample maps,

681
01:13:57,119 --> 01:14:01,119
which were derived from the TV in real time,

682
01:14:01,119 --> 01:14:03,119
and that was a very useful tool to us.

683
01:14:03,119 --> 01:14:07,119
A sample inventory, a film usage inventory,

684
01:14:07,119 --> 01:14:15,119
and a station locations, again, resected from the TV pans.

685
01:14:15,119 --> 01:14:21,119
By the end of last week, we could receive black and white two-time enlargements of all film.

686
01:14:21,119 --> 01:14:25,119
These are the typical drugstore quality prints.

687
01:14:25,119 --> 01:14:30,119
And sooner or later, we'll get good quality, so our analysis was very brief.

688
01:14:30,119 --> 01:14:33,119
We've assembled all the panoramas.

689
01:14:33,119 --> 01:14:36,119
Sample location studies are a mirroring completion.

690
01:14:36,119 --> 01:14:41,119
The film inventory is also a mirroring completion.

691
01:14:41,119 --> 01:14:44,119
The geological analysis is still in its infancy,

692
01:14:44,119 --> 01:14:48,119
and I suspect it should progress rapidly now that we've got all this inventory in and over with.

693
01:14:48,119 --> 01:14:54,119
The geistix of damage, it picks you up, takes time to get them organized.

694
01:14:54,119 --> 01:14:58,119
We've had one session with a crew in the LRL with samples,

695
01:14:58,119 --> 01:15:02,119
and most of our questions need samples in hand.

696
01:15:02,119 --> 01:15:07,119
And those will, I'm sure, will be able to discuss later.

697
01:15:07,119 --> 01:15:11,119
And so the questions that have gone relate more to surface observations

698
01:15:11,119 --> 01:15:13,119
that maybe we can amplify.

699
01:15:13,119 --> 01:15:17,119
And some of these are questions that we've asked you before,

700
01:15:17,119 --> 01:15:23,119
but I have a few Polaroid prints of these photos that maybe conjossil our minds

701
01:15:23,119 --> 01:15:31,119
and assistant refining some of the answers that we've gotten on the debris

702
01:15:31,119 --> 01:15:34,119
after the EVAs or on transfer.

703
01:15:34,119 --> 01:15:40,119
Our photogelotic mapping group primarily talked about rays by their whiteness.

704
01:15:40,119 --> 01:15:44,119
There were a few spots where they thought they were seeing dark rays.

705
01:15:44,119 --> 01:15:48,119
Now you recognize both light and dark colored rays,

706
01:15:48,119 --> 01:15:51,119
particularly the South Ray picture.

707
01:15:51,119 --> 01:15:56,119
If I could have a slide, one please,

708
01:15:57,119 --> 01:16:00,119
which is the South Ray panorama,

709
01:16:00,119 --> 01:16:04,119
and the print I've just given to the crew, a single frame from that.

710
01:16:04,119 --> 01:16:07,119
There, I think we can see light and dark.

711
01:16:07,119 --> 01:16:10,119
And the real question I'm after is,

712
01:16:10,119 --> 01:16:15,119
what led you to say that you were on or off a ray?

713
01:16:15,119 --> 01:16:20,119
And secondly, were there any visible differences in the rock types

714
01:16:20,119 --> 01:16:25,119
as you drove by or had a chance of sampling ray material?

715
01:16:25,119 --> 01:16:28,119
Yeah.

716
01:16:28,119 --> 01:16:31,119
Sure looks that way.

717
01:16:31,119 --> 01:16:34,119
The hills are at the bottom.

718
01:16:34,119 --> 01:16:39,119
Yeah, I think the thumb thread goes in the upper right.

719
01:16:39,119 --> 01:16:46,119
Good, the projection just give that a 180 please, around a horizontal axis.

720
01:16:46,119 --> 01:16:50,119
That one's got the same problem. There we go.

721
01:16:50,119 --> 01:16:54,119
Now it's a hill instead of a hole.

722
01:16:55,119 --> 01:16:59,119
This is your pan from station four.

723
01:16:59,119 --> 01:17:04,119
You see that black line coming over the...

724
01:17:04,119 --> 01:17:09,119
This photo really doesn't do that in some justice.

725
01:17:09,119 --> 01:17:12,119
All right, prints never do.

726
01:17:12,119 --> 01:17:15,119
Well, I mean, you really have to see it to believe it.

727
01:17:15,119 --> 01:17:21,119
That white is so much quieter than the contrast that we're able to get out of the photographs.

728
01:17:21,119 --> 01:17:26,119
I think when I looked at it,

729
01:17:26,119 --> 01:17:30,119
my assessment of this,

730
01:17:30,119 --> 01:17:32,119
which is kind of bad place,

731
01:17:32,119 --> 01:17:35,119
was that it was a black ray coming out.

732
01:17:35,119 --> 01:17:37,119
The right one there on the photograph.

733
01:17:37,119 --> 01:17:39,119
And it probably went right down that,

734
01:17:39,119 --> 01:17:45,119
as you know, the photograph that showed the black area coming out of South Ray.

735
01:17:45,119 --> 01:17:46,119
Right there.

736
01:17:46,119 --> 01:17:49,119
And there's a series of black blocks.

737
01:17:49,119 --> 01:17:51,119
There's a bunch right there.

738
01:17:51,119 --> 01:17:52,119
Left edge.

739
01:17:52,119 --> 01:17:54,119
And there's also...

740
01:17:54,119 --> 01:17:56,119
Charlie described this in real time.

741
01:17:56,119 --> 01:18:01,119
There's some more black blocks in there.

742
01:18:01,119 --> 01:18:05,119
And they seem to come out in ray patterns too.

743
01:18:05,119 --> 01:18:06,119
And she think Charlie,

744
01:18:06,119 --> 01:18:10,119
that's one spectacular crater.

745
01:18:10,119 --> 01:18:13,119
That ray coming down the South...

746
01:18:13,119 --> 01:18:16,119
South right edge might have been the ray that made...

747
01:18:16,119 --> 01:18:19,119
or at least part of it that made Survey Ridge.

748
01:18:19,119 --> 01:18:25,119
Because it just ran right across those wreck trap craters

749
01:18:25,119 --> 01:18:28,119
and we could see it going all the way down.

750
01:18:28,119 --> 01:18:30,119
Is that the bright ray you're talking about in the lower right?

751
01:18:30,119 --> 01:18:33,119
This ray right here, Bill, came right through study,

752
01:18:33,119 --> 01:18:36,119
right up over and right out Survey Ridge.

753
01:18:36,119 --> 01:18:39,119
So that was the source of your terrific block field there?

754
01:18:39,119 --> 01:18:45,119
Man, and just amazing how much rocks of rascal lay down.

755
01:18:45,119 --> 01:18:48,119
I just couldn't believe it.

756
01:18:48,119 --> 01:18:50,119
Try to build the in close to that thing.

757
01:18:50,119 --> 01:18:52,119
It would probably have been very interesting.

758
01:18:52,119 --> 01:18:55,119
We should have had another EVA to find out.

759
01:18:55,119 --> 01:18:58,119
I think so heat flow won.

760
01:18:58,119 --> 01:19:02,119
The reason we call it our ray was really a...

761
01:19:02,119 --> 01:19:06,119
a bunch of secondary craters and a bunch of blocks.

762
01:19:06,119 --> 01:19:10,119
And they thinned and thickened as we...

763
01:19:10,119 --> 01:19:12,119
I think traverse raised,

764
01:19:12,119 --> 01:19:16,119
raised, but we never did get completely out of blocks

765
01:19:16,119 --> 01:19:19,119
to the south, to the traverse to the south.

766
01:19:19,119 --> 01:19:24,119
There were always five, at least three to five percent

767
01:19:24,119 --> 01:19:27,119
of the surface head cobbles.

768
01:19:27,119 --> 01:19:33,119
And I say cobbles, 20 centimeter blocks and larger.

769
01:19:33,119 --> 01:19:35,119
And the blocks were generally asymmetrical

770
01:19:35,119 --> 01:19:38,119
on us to the crater or the crater shape.

771
01:19:38,119 --> 01:19:42,119
Was elongated or just a great spattering of craters

772
01:19:42,119 --> 01:19:45,119
as why you're calling them secondaries?

773
01:19:45,119 --> 01:19:50,119
I think subjectively we felt they were oriented from south ray all the time.

774
01:19:50,119 --> 01:19:54,119
There was really just a subjective feel as we were driving by them.

775
01:19:54,119 --> 01:19:58,119
There were a lot of the blocks that were not associated with any craters.

776
01:19:58,119 --> 01:20:02,119
There would be a pile of a series of secondaries,

777
01:20:02,119 --> 01:20:06,119
but around for a couple hundred meters it'd be more blocks.

778
01:20:06,119 --> 01:20:09,119
Like as far as you could see, there'd be blocks just scattered over the surface

779
01:20:09,119 --> 01:20:12,119
that were not associated with any secondaries.

780
01:20:12,119 --> 01:20:15,119
But the true secondaries were...

781
01:20:15,119 --> 01:20:19,119
We did see some that were classic where you could...

782
01:20:19,119 --> 01:20:24,119
The ejector was down range from an important right to south ray.

783
01:20:24,119 --> 01:20:27,119
Station 4 for instance, what's the one that was...

784
01:20:27,119 --> 01:20:30,119
Can I have slide 4 please?

785
01:20:30,119 --> 01:20:35,119
I might add that these black rays and the black blocks that you see here

786
01:20:35,119 --> 01:20:39,119
were also evident at baby ray.

787
01:20:39,119 --> 01:20:42,119
Can you rotate that one too?

788
01:20:42,119 --> 01:20:48,119
And to a lesser degree, the sampling at North Ray

789
01:20:48,119 --> 01:20:52,119
had an appearance of being black and white matrixed.

790
01:20:52,119 --> 01:20:54,119
Black and white rocks.

791
01:20:54,119 --> 01:20:58,119
To these black streaks go into the crater themselves down,

792
01:20:58,119 --> 01:21:01,119
vertically down into the sides of the crater.

793
01:21:01,119 --> 01:21:04,119
It's south ray, yeah. That one on the left that you saw there was...

794
01:21:04,119 --> 01:21:07,119
You could track it over the rim and back right across the rim.

795
01:21:07,119 --> 01:21:09,119
And can you see that from orbit?

796
01:21:09,119 --> 01:21:14,119
You can see a lot of these fresh, but like black street craters.

797
01:21:14,119 --> 01:21:16,119
This one...

798
01:21:16,119 --> 01:21:22,119
South Ray does not have nearly the obvious dark streaks that run down inside

799
01:21:22,119 --> 01:21:25,119
and outside that many of the other craters do.

800
01:21:25,119 --> 01:21:30,119
There was dark material, dark appearing materials were obvious in the crater interior.

801
01:21:30,119 --> 01:21:36,119
But I never recognized it as being a ray that was thrown out with a radio dimension.

802
01:21:36,119 --> 01:21:41,119
Yeah, I think looking at the photography, the feeling we got from looking at South Ray

803
01:21:41,119 --> 01:21:44,119
was that that black streak was just an absence of any rays.

804
01:21:44,119 --> 01:21:52,119
But I think it's from the blocks that must be black ray material.

805
01:21:52,119 --> 01:21:53,119
Dark material.

806
01:21:53,119 --> 01:21:58,119
Maybe the dark matrix rocks would produce that darkening.

807
01:21:58,119 --> 01:22:03,119
It's petered out a lot faster than the white rays of...

808
01:22:03,119 --> 01:22:06,119
You know, within a quarter of a cratered image.

809
01:22:06,119 --> 01:22:09,119
From the bottom of it.

810
01:22:09,119 --> 01:22:12,119
Those could disappear just because of their general appearance.

811
01:22:12,119 --> 01:22:13,119
Could.

812
01:22:13,119 --> 01:22:18,119
Like the local regulates, the white ones being so obviously different.

813
01:22:18,119 --> 01:22:20,119
You'd be easy to recognize.

814
01:22:20,119 --> 01:22:23,119
I suspect why the mappers did the same thing.

815
01:22:24,119 --> 01:22:30,119
Here's your pan, John, from... or part of it, looking up sun.

816
01:22:30,119 --> 01:22:33,119
And this crater you suggested was a secondary.

817
01:22:33,119 --> 01:22:39,119
And therefore, the sampling that you were doing primarily over there to the left corner is where the rover is.

818
01:22:39,119 --> 01:22:44,119
Would be South Ray ejecta as the principal source.

819
01:22:44,119 --> 01:22:46,119
There's one reason we wanted to move you on.

820
01:22:46,119 --> 01:22:52,119
And I think that was a good decision now that we look at your photographs and from what you told us.

821
01:22:52,119 --> 01:22:59,119
We sample this crater up on this close-in rim and down the rim a little bit.

822
01:22:59,119 --> 01:23:00,119
But I...

823
01:23:00,119 --> 01:23:02,119
Man, that's not a classic secondary.

824
01:23:02,119 --> 01:23:04,119
I never saw one.

825
01:23:04,119 --> 01:23:06,119
That's...

826
01:23:06,119 --> 01:23:09,119
Type locality if you're part of the geological bridge.

827
01:23:09,119 --> 01:23:11,119
And you can see the debris from there.

828
01:23:11,119 --> 01:23:13,119
You just scattered all out in here to...

829
01:23:13,119 --> 01:23:15,119
The rover's back over here.

830
01:23:15,119 --> 01:23:16,119
Down slope.

831
01:23:16,119 --> 01:23:18,119
You can see it right in the left corner, just the edge of it.

832
01:23:18,119 --> 01:23:19,119
Oh, yeah.

833
01:23:19,119 --> 01:23:21,119
And I think you're standing there, Charlie.

834
01:23:22,119 --> 01:23:24,119
Probably on my face.

835
01:23:27,119 --> 01:23:28,119
Okay.

836
01:23:31,119 --> 01:23:33,119
Okay, the...

837
01:23:33,119 --> 01:23:39,119
Related to this are some of the craters that you called indirated and had clods around them.

838
01:23:39,119 --> 01:23:42,119
The guy who has photos, seven, please.

839
01:23:42,119 --> 01:23:45,119
And that'll probably need a 182.

840
01:23:46,119 --> 01:23:47,119
Okay.

841
01:23:50,119 --> 01:23:51,119
Oh, no.

842
01:23:51,119 --> 01:23:52,119
Number seven.

843
01:23:52,119 --> 01:23:53,119
Oh, yeah.

844
01:23:53,119 --> 01:23:54,119
That's plum.

845
01:23:54,119 --> 01:23:55,119
Okay.

846
01:23:55,119 --> 01:23:57,119
Now that plum's got a little bench in it.

847
01:23:57,119 --> 01:24:09,119
And on the pre-mission work, there were quite a lot of them that had benches and suggested that there was an indirated layer that was shallow compared to what the crater counts said that the age of that whole surface had to be.

848
01:24:09,119 --> 01:24:18,119
We just heard Covatch tell us it was a very thick regular here, which is what it should have had by the cratering stories.

849
01:24:18,119 --> 01:24:20,119
And yet there's always this little bench.

850
01:24:20,119 --> 01:24:28,119
We're wondering now whether that bench has some relationship to the ejector from the South Ray and North Ray craters.

851
01:24:28,119 --> 01:24:38,119
And therefore, it might be what you brought up here on the rim of plum and some of the pre-ray indirated regulates.

852
01:24:39,119 --> 01:24:45,119
Do you have any thoughts that could go into that?

853
01:24:45,119 --> 01:24:48,119
That one, what I was calling the indirated reguleth fill.

854
01:24:48,119 --> 01:24:49,119
What?

855
01:24:49,119 --> 01:24:50,119
No.

856
01:24:50,119 --> 01:24:56,119
The indirated reguleth I was talking about was two meter size craters.

857
01:24:56,119 --> 01:24:57,119
Two meters.

858
01:24:57,119 --> 01:24:58,119
Yeah, two meter size.

859
01:24:58,119 --> 01:25:13,119
And there were little teeny quads, no bigger than a grapefruit, and that were symmetrically around a very shallow crater that had a hackley black glass right in the center of these little craters.

860
01:25:13,119 --> 01:25:16,119
And the biggest one was no more than two meters.

861
01:25:16,119 --> 01:25:21,119
You see down in the plum, see those that outline of rocks down in there?

862
01:25:22,119 --> 01:25:23,119
No, keep going down.

863
01:25:23,119 --> 01:25:24,119
Right here?

864
01:25:24,119 --> 01:25:25,119
No, over here.

865
01:25:25,119 --> 01:25:26,119
What do you point to?

866
01:25:26,119 --> 01:25:27,119
Okay.

867
01:25:27,119 --> 01:25:30,119
See those rocks right in there?

868
01:25:30,119 --> 01:25:31,119
I think...

869
01:25:31,119 --> 01:25:33,119
Near the bottom of the room.

870
01:25:33,119 --> 01:25:46,119
Yeah, I wouldn't be surprised, but what the most likely candidate for a rock that was from down, either in the bottom of plum,

871
01:25:46,119 --> 01:25:55,119
or from the lower part of flag was that rock piece of rock that we chipped off of.

872
01:25:55,119 --> 01:25:58,119
It was located right in the center.

873
01:25:58,119 --> 01:26:00,119
Yeah, just up to the same.

874
01:26:00,119 --> 01:26:02,119
And I...

875
01:26:02,119 --> 01:26:04,119
Because that had been...

876
01:26:04,119 --> 01:26:06,119
That was well under the...

877
01:26:06,119 --> 01:26:13,119
I mean, it was the submerged rock, and I got the feeling that it was sort of local to the area.

878
01:26:14,119 --> 01:26:20,119
I mean, I don't see how it could have been from South Ray, or unless that was extremely soft when it plunked in there.

879
01:26:20,119 --> 01:26:25,119
I didn't rule out that, but I mean, that would be the most likely candidate of the ones we could get to.

880
01:26:25,119 --> 01:26:26,119
We could...

881
01:26:26,119 --> 01:26:31,119
The no way we could have got down in there and got those rocks.

882
01:26:31,119 --> 01:26:32,119
That's true.

883
01:26:32,119 --> 01:26:33,119
And gotten back.

884
01:26:36,119 --> 01:26:38,119
So, you took your tether away from me.

885
01:26:38,119 --> 01:26:40,119
I don't imagine you want to explore those craters.

886
01:26:43,119 --> 01:26:47,119
Okay, the buster crater of photo 8, please.

887
01:26:52,119 --> 01:26:55,119
This is your partial pan of buster.

888
01:26:55,119 --> 01:26:59,119
Again, not a winter for photographic work.

889
01:26:59,119 --> 01:27:03,119
It's at least as good as the astrologers pictures, though.

890
01:27:05,119 --> 01:27:11,119
You described that there was a southwestern, northeast, boldery field in here.

891
01:27:11,119 --> 01:27:13,119
We're looking almost down the sun.

892
01:27:13,119 --> 01:27:16,119
I'm wondering, I can't tell in these photographs,

893
01:27:16,119 --> 01:27:20,119
would you tell whether there are blocks over in there, and therefore,

894
01:27:20,119 --> 01:27:24,119
your impression of this streak?

895
01:27:25,119 --> 01:27:26,119
Well, I'll cross it.

896
01:27:26,119 --> 01:27:30,119
It could not be salted by because you're looking down the sun.

897
01:27:30,119 --> 01:27:31,119
Well, I might have been...

898
01:27:31,119 --> 01:27:35,119
I didn't really mean to say southeast northwest.

899
01:27:35,119 --> 01:27:44,119
The predominance of blocks and buster were oriented in this direction across that this way,

900
01:27:44,119 --> 01:27:47,119
which is northeast southwest.

901
01:27:47,119 --> 01:27:48,119
Yeah.

902
01:27:48,119 --> 01:27:50,119
That's what you said.

903
01:27:50,119 --> 01:27:52,119
And you're reconfirming that.

904
01:27:52,119 --> 01:27:54,119
And reconfirming that.

905
01:27:54,119 --> 01:27:59,119
Over in this area, you can see some of the blocks, but not nearly as many as here.

906
01:27:59,119 --> 01:28:11,119
Now, we can barely see the bottom of buster, but the bottom of buster is covered with blocks that were up to two meters across,

907
01:28:11,119 --> 01:28:16,119
and showed no orientation in any direction.

908
01:28:16,119 --> 01:28:19,119
My feeling over here, due to the...

909
01:28:19,119 --> 01:28:27,119
There were blocks in this area, but they were not as numerous as this pattern in here.

910
01:28:27,119 --> 01:28:35,119
And so the blocks that you're on the side you were standing would have been derived primarily from that hole,

911
01:28:35,119 --> 01:28:40,119
and not from the impacting material.

912
01:28:40,119 --> 01:28:45,119
It has a appearance of a secondary from South Ray, and this kind of a photograph.

913
01:28:45,119 --> 01:28:46,119
You're in a description of you.

914
01:28:46,119 --> 01:28:48,119
You'd not go with that interpretation.

915
01:28:48,119 --> 01:28:50,119
Well, if it is, it's the biggest one I've ever seen.

916
01:28:50,119 --> 01:28:52,119
So that is a big crater.

917
01:28:52,119 --> 01:28:58,119
From here to here, it was at least 50 meters.

918
01:28:58,119 --> 01:29:00,119
At least, yeah.

919
01:29:00,119 --> 01:29:07,119
And the size of those blocks and the depth of that crater in South Ray is six kilometers away.

920
01:29:07,119 --> 01:29:10,119
That had to be one big block at a pound of it in there.

921
01:29:10,119 --> 01:29:14,119
And I don't know whether you can even excavate something that large.

922
01:29:14,119 --> 01:29:16,119
That's too large to be.

923
01:29:16,119 --> 01:29:19,119
I don't really think it's a secondary person.

924
01:29:19,119 --> 01:29:25,119
So I'm not feeling that looking at it was a primary because I couldn't conceive of how you'd get one from...

925
01:29:25,119 --> 01:29:30,119
Of course it could have maybe been a secondary from one of those big craters way down South.

926
01:29:30,119 --> 01:29:32,119
That's impossible to get you.

927
01:29:32,119 --> 01:29:43,119
So that's either local bedrock or some of the flat or the thrown out material from Spook that we're seeing there in the floor in the walls.

928
01:29:43,119 --> 01:29:45,119
Spook didn't look like that at all.

929
01:29:45,119 --> 01:29:47,119
This was a lot fresher crater.

930
01:29:47,119 --> 01:29:49,119
I think it's the over-sertify of this business.

931
01:29:49,119 --> 01:29:52,119
Man, because it won't tell where that rascal came from.

932
01:29:57,119 --> 01:30:01,119
Okay, I'd like to have slide nine, please.

933
01:30:01,119 --> 01:30:09,119
This is North Ray Crater.

934
01:30:09,119 --> 01:30:16,119
And there were arguments among you guys and arguments among ours as to whether we're seeing layering in there.

935
01:30:16,119 --> 01:30:21,119
And I think the layering that you were talking about, John, is over in the right part where there's a dominance of blocks.

936
01:30:21,119 --> 01:30:24,119
Is that a true statement?

937
01:30:26,119 --> 01:30:28,119
Right there.

938
01:30:29,119 --> 01:30:32,119
That's certainly one of the best candidates for...

939
01:30:32,119 --> 01:30:40,119
It's just hard to imagine how the blocks would either all slump down there and end up at that spot or...

940
01:30:42,119 --> 01:30:46,119
Yeah, slump down there and end up there.

941
01:30:46,119 --> 01:30:52,119
You know, in our geology trips, we ran across a lot of contacts.

942
01:30:52,119 --> 01:30:55,119
It was a great deal more subtle than that one right there.

943
01:30:55,119 --> 01:30:57,119
That's why I picked it.

944
01:30:58,119 --> 01:31:02,119
There's a better view of that as you get on further to the north, Bill.

945
01:31:02,119 --> 01:31:08,119
I think it shows it a little bit deeper down, but there's certainly if there is any...

946
01:31:08,119 --> 01:31:11,119
The right polarometric pan is a...

947
01:31:11,119 --> 01:31:14,119
I should have had rather than the left.

948
01:31:14,119 --> 01:31:17,119
People's in use when I needed to make the picture.

949
01:31:17,119 --> 01:31:23,119
You know, up at going up Stone Mountain, there was one other crater that we were looking into.

950
01:31:23,119 --> 01:31:32,119
We were driving up Stone Mountain where we could see what looked to be more like an halftrop than anything I've seen so far.

951
01:31:32,119 --> 01:31:38,119
And it was the same kind of thing, only it wasn't broken up like that. It was just one solid piece.

952
01:31:38,119 --> 01:31:40,119
I don't think there was any way we'd gotten up the hill to it.

953
01:31:40,119 --> 01:31:42,119
We've got some photographs of that.

954
01:31:42,119 --> 01:31:46,119
And it shows up on a 16-millimeter photography as we're driving up there.

955
01:31:46,119 --> 01:31:50,119
And I can point it out to you, but it was about that...

956
01:31:50,119 --> 01:31:55,119
That one-third of the way down from the top to the floor.

957
01:31:55,119 --> 01:31:58,119
The same kind of...

958
01:31:58,119 --> 01:32:06,119
But that's the only two places where I'd really call out what I would hazard to guess that that was out.

959
01:32:06,119 --> 01:32:07,119
That was outcrop.

960
01:32:07,119 --> 01:32:14,119
Off to the left there, you can see a vertical string of blocks right in the middle, a firewall, yeah.

961
01:32:15,119 --> 01:32:20,119
And were there any visual observations you made on that that...

962
01:32:20,119 --> 01:32:28,119
Well, again, I got to impression we had areas, quite areas, and dark areas.

963
01:32:28,119 --> 01:32:33,119
And maybe the darkening was just because of the shadows caused by the rocks.

964
01:32:33,119 --> 01:32:38,119
I got to feel those with the dark blocks like house rock, like Charlie does.

965
01:32:38,119 --> 01:32:42,119
And I got to feel in their places where there were strings of white blocks too.

966
01:32:42,119 --> 01:32:48,119
These rocks right here that are more buried and the regulars is deeper in this area

967
01:32:48,119 --> 01:32:53,119
are all white matrix rocks around this way.

968
01:32:53,119 --> 01:32:57,119
And really right out from this little block here is house rocks that's here,

969
01:32:57,119 --> 01:33:00,119
and that is predominantly a black matrix drop.

970
01:33:00,119 --> 01:33:07,119
And I counted nine radial block trails out of that crater.

971
01:33:07,119 --> 01:33:14,119
One, two, three, four, five, six, seven, and there's a couple over here.

972
01:33:14,119 --> 01:33:19,119
It gave you the pressure that you could take, track them from the floor all the way out over the rim,

973
01:33:19,119 --> 01:33:22,119
at least as far as we could see.

974
01:33:22,119 --> 01:33:26,119
The stink zones of blocks.

975
01:33:26,119 --> 01:33:27,119
Good.

976
01:33:27,119 --> 01:33:35,119
As a rascally, actual craters don't really exhibit the classical overturned flap that we've been looking at there.

977
01:33:35,119 --> 01:33:41,119
More complicated than that when they all get shuffling around on themselves.

978
01:33:41,119 --> 01:33:47,119
In here, as I said, we had impression that the regulars was more loosely consolidated

979
01:33:47,119 --> 01:33:50,119
because of a footprint impression I had.

980
01:33:50,119 --> 01:33:55,119
Down at South Ray, I had a correction down at house rock.

981
01:33:55,119 --> 01:34:00,119
We already commented that we couldn't even get those palms to the shovel or the scoop in.

982
01:34:00,119 --> 01:34:05,119
And around the rover, which was seeing right back out here, we had the same problem.

983
01:34:05,119 --> 01:34:09,119
And you don't get the impression from here, but the slope going down to that block

984
01:34:09,119 --> 01:34:16,119
where we'd have to go down to to get a picture of the bottom of that crater was not the kind of thing I'd want Charlie to be doing

985
01:34:16,119 --> 01:34:18,119
without having that 100-foot line on us.

986
01:34:18,119 --> 01:34:21,119
So we didn't get any pictures of the bottom of it.

987
01:34:21,119 --> 01:34:26,119
Well, wait a little bit, we get the pan-camera stuff looking to the bottom, I guess.

988
01:34:26,119 --> 01:34:27,119
No.

989
01:34:27,119 --> 01:34:29,119
Or Ken's words on it.

990
01:34:29,119 --> 01:34:33,119
As you can see, what's going down there, but I'd like to be able to get him back.

991
01:34:33,119 --> 01:34:35,119
Yes. Me too.

992
01:34:35,119 --> 01:34:47,119
As you can see here, the white matrix rocks had more filleted and appeared to be more covered with regular Earth than the larger rocks around it,

993
01:34:47,119 --> 01:34:52,119
over here to the north where the black matrix rocks, the house rock was.

994
01:34:52,119 --> 01:34:58,119
It had some filleting, but it was not nearly so pronounced as this area to the south.

995
01:34:58,119 --> 01:35:03,119
Would the house rock TV pan do you have anything you'd want to point at them?

996
01:35:03,119 --> 01:35:06,119
I've got that up there in the slide if you want to.

997
01:35:06,119 --> 01:35:08,119
It's lousy, but it's...

998
01:35:08,119 --> 01:35:09,119
I don't think so.

999
01:35:09,119 --> 01:35:10,119
...to point things out.

1000
01:35:10,119 --> 01:35:11,119
Okay, so big one.

1001
01:35:11,119 --> 01:35:15,119
Can I get that out of the piece that the layer is looking at?

1002
01:35:15,119 --> 01:35:17,119
I'd like to point that below the surface rock.

1003
01:35:17,119 --> 01:35:21,119
I guess it's a quarter of the way down to the bottom.

1004
01:35:21,119 --> 01:35:22,119
But it's really hard to tell.

1005
01:35:22,119 --> 01:35:25,119
You know, that rascal is half a mile across.

1006
01:35:25,119 --> 01:35:29,119
So some of those rocks sitting in there must be almost as big as house rock.

1007
01:35:29,119 --> 01:35:31,119
It's really hard to say.

1008
01:35:31,119 --> 01:35:33,119
We didn't ever see the bottom.

1009
01:35:33,119 --> 01:35:39,119
It's about a quarter of the way down from where we could see.

1010
01:35:39,119 --> 01:35:49,119
I would imagine that the bottom of North Ray looks very much like a buster, the bottom of buster with bigger blocks.

1011
01:35:49,119 --> 01:35:51,119
Hopefully the pan camera will show that.

1012
01:35:51,119 --> 01:35:55,119
You didn't want to get close to that beauty.

1013
01:35:55,119 --> 01:35:58,119
Right in this area.

1014
01:35:58,119 --> 01:36:04,119
There was a bench down in here that you could probably have walked out on and seen the bottom.

1015
01:36:04,119 --> 01:36:07,119
But if you had fallen off of us, swallow your whole legs.

1016
01:36:07,119 --> 01:36:17,119
Sorry that you get to conflate controllers, Matt, because you didn't get back to the limon time.

1017
01:36:21,119 --> 01:36:25,119
So, you know, you can't get back to the limon time.

1018
01:36:25,119 --> 01:36:27,119
You can't get back to the limon time.

1019
01:36:27,119 --> 01:36:29,119
You can't get back to the limon time.

1020
01:36:29,119 --> 01:36:31,119
You can't get back to the limon time.

1021
01:36:31,119 --> 01:36:33,119
You can't get back to the limon time.

1022
01:36:33,119 --> 01:36:35,119
You can't get back to the limon time.

1023
01:36:35,119 --> 01:36:37,119
You can't get back to the limon time.

1024
01:36:37,119 --> 01:36:39,119
You can't get back to the limon time.

1025
01:36:39,119 --> 01:36:41,119
You can't get back to the limon time.

1026
01:36:41,119 --> 01:36:43,119
You can't get back to the limon time.

1027
01:36:43,119 --> 01:36:45,119
You can't get back to the limon time.

1028
01:36:45,119 --> 01:36:47,119
You can't get back to the limon time.

1029
01:36:47,119 --> 01:36:49,119
You can't get back to the limon time.
