1
00:00:09,519 --> 00:00:16,070
things are looking good

2
00:00:16,080 --> 00:00:20,950
entry interface

3
00:00:25,509 --> 00:00:22,390
we're not beginning to feel the

4
00:00:27,109 --> 00:00:25,519
atmosphere uh as we go in here

5
00:00:29,589 --> 00:00:27,119
uh it is reporting that we are seeing

6
00:00:32,870 --> 00:00:29,599
g's on the order of uh 11 to 12 earth

7
00:00:35,830 --> 00:00:34,549
2 is starting

8
00:00:39,910 --> 00:00:35,840
we are now getting telemetry from

9
00:00:46,709 --> 00:00:41,670
we should have parachute deploy around

10
00:00:46,719 --> 00:00:49,910
the parachute is deployed

11
00:00:49,920 --> 00:00:53,510
we are decelerating

12
00:00:57,029 --> 00:00:55,350
has separated on the ground

13
00:01:01,910 --> 00:00:57,039
we're down to 90 meters per second at an

14
00:01:01,920 --> 00:01:08,230
standing by for bachelor separation

15
00:01:08,240 --> 00:01:15,429
we are in powered flight

16
00:01:19,350 --> 00:01:16,710
we're at altitude of one kilometer

17
00:01:36,950 --> 00:01:21,350
standing by for sky crane

18
00:01:36,960 --> 00:02:03,350
touchdown

19
00:02:03,360 --> 00:02:30,710
you got a thumbnail

20
00:02:34,229 --> 00:02:32,309
welcome to nasa's jet propulsion

21
00:02:35,990 --> 00:02:34,239
laboratory in pasadena california i

22
00:02:37,910 --> 00:02:36,000
think that video just brought a few

23
00:02:39,509 --> 00:02:37,920
tears to a few of the eyes up here on

24
00:02:41,270 --> 00:02:39,519
the podium let me introduce the

25
00:02:42,949 --> 00:02:41,280
panelists that we have today that are

26
00:02:45,030 --> 00:02:42,959
going to give us an update on the rover

27
00:02:47,430 --> 00:02:45,040
and a little bit of the outlook for what

28
00:02:48,470 --> 00:02:47,440
will come next um joining us right now

29
00:02:50,630 --> 00:02:48,480
we have

30
00:02:52,070 --> 00:02:50,640
michael watkins from jpl he's the

31
00:02:55,750 --> 00:02:52,080
mission manager for the mars science

32
00:03:03,750 --> 00:02:58,390
miguel san martin from jpl the chief

33
00:03:11,030 --> 00:03:06,229
sarah milkovich from jpl she's the

34
00:03:15,430 --> 00:03:13,270
and john grotzinger of caltech the

35
00:03:18,390 --> 00:03:15,440
project scientist for the mission and

36
00:03:19,750 --> 00:03:18,400
we'll begin with mike watkins okay good

37
00:03:21,830 --> 00:03:19,760
morning everyone

38
00:03:23,830 --> 00:03:21,840
welcome to mars or welcome back to mars

39
00:03:26,390 --> 00:03:23,840
if you were here last night

40
00:03:28,390 --> 00:03:26,400
the uh the surface mission of curiosity

41
00:03:30,390 --> 00:03:28,400
has now begun

42
00:03:31,990 --> 00:03:30,400
now for a long time those of us uh on

43
00:03:33,990 --> 00:03:32,000
the project and knew that we had to get

44
00:03:36,229 --> 00:03:34,000
through some big events launch was a big

45
00:03:38,149 --> 00:03:36,239
one for us and of course edl was an

46
00:03:40,470 --> 00:03:38,159
enormous one for us

47
00:03:42,710 --> 00:03:40,480
but you know we built this rover not

48
00:03:45,190 --> 00:03:42,720
just to be launched or not just to land

49
00:03:47,670 --> 00:03:45,200
on mars but to actually drive on mars

50
00:03:49,350 --> 00:03:47,680
and execute a very complex and beautiful

51
00:03:52,470 --> 00:03:49,360
science mission

52
00:03:54,869 --> 00:03:52,480
we have ended one phase of the mission

53
00:03:56,630 --> 00:03:54,879
much to our enjoyment and and to the to

54
00:03:59,110 --> 00:03:56,640
the joy of a lot of folks here in the

55
00:04:01,350 --> 00:03:59,120
audience and on our own team

56
00:04:02,789 --> 00:04:01,360
but another part has just begun

57
00:04:04,550 --> 00:04:02,799
and really the it's really the

58
00:04:06,149 --> 00:04:04,560
fundamental reason we built the rover

59
00:04:07,670 --> 00:04:06,159
it's really the purpose of the rover

60
00:04:09,750 --> 00:04:07,680
we're just starting that mission we're

61
00:04:13,030 --> 00:04:09,760
not we're not ending it

62
00:04:15,190 --> 00:04:13,040
now about two hours after uh landing um

63
00:04:16,310 --> 00:04:15,200
about just just before 1am in the

64
00:04:18,469 --> 00:04:16,320
morning

65
00:04:21,749 --> 00:04:18,479
curiosity called us

66
00:04:23,990 --> 00:04:21,759
via the next overpass of mars odyssey

67
00:04:25,990 --> 00:04:24,000
so mars odyssey

68
00:04:27,670 --> 00:04:26,000
was overhead during edl

69
00:04:30,150 --> 00:04:27,680
and of course it comes around two hours

70
00:04:32,710 --> 00:04:30,160
later mars has rotated a little bit

71
00:04:34,390 --> 00:04:32,720
and uh and uh was still over the horizon

72
00:04:37,510 --> 00:04:34,400
and we were able to have a short talk

73
00:04:39,749 --> 00:04:37,520
with with curiosity via mars odyssey

74
00:04:41,670 --> 00:04:39,759
and she told us that she is in surface

75
00:04:44,870 --> 00:04:41,680
nominal mode she correctly transitioned

76
00:04:46,870 --> 00:04:44,880
from from edl mode to surface nominal

77
00:04:48,710 --> 00:04:46,880
not in not in safe mode in regular

78
00:04:50,150 --> 00:04:48,720
nominal operational mode

79
00:04:52,390 --> 00:04:50,160
and is otherwise very healthy we had a

80
00:04:54,390 --> 00:04:52,400
very successful uhf pass we got some

81
00:04:57,189 --> 00:04:54,400
images that i'll show in a little bit

82
00:04:59,430 --> 00:04:57,199
and we are go for all planned sol one

83
00:05:03,909 --> 00:04:59,440
activities

84
00:05:06,629 --> 00:05:03,919
dominated by in some sense kind of

85
00:05:08,790 --> 00:05:06,639
boring activities uh checking out the

86
00:05:10,710 --> 00:05:08,800
rover making sure it's healthy

87
00:05:12,870 --> 00:05:10,720
deploying the antenna

88
00:05:16,550 --> 00:05:12,880
on saw two we deploy the remote sensing

89
00:05:17,909 --> 00:05:16,560
mast so the high gain antenna

90
00:05:19,430 --> 00:05:17,919
the rover looks kind of like this right

91
00:05:21,510 --> 00:05:19,440
now now you're used to seeing the rover

92
00:05:24,070 --> 00:05:21,520
like it is in that picture with its eyes

93
00:05:26,390 --> 00:05:24,080
up and with an antenna deployed in fact

94
00:05:28,629 --> 00:05:26,400
we are stowed down here with the with

95
00:05:30,790 --> 00:05:28,639
the with the remote sensing mass down

96
00:05:32,710 --> 00:05:30,800
and we're about to deploy this little

97
00:05:34,790 --> 00:05:32,720
antenna here this allows us to talk

98
00:05:36,550 --> 00:05:34,800
directly to the earth with enough gain

99
00:05:39,510 --> 00:05:36,560
that it can actually send data to us and

100
00:05:41,749 --> 00:05:39,520
be more easily talked to by us

101
00:05:43,189 --> 00:05:41,759
um later a day or so from now we're

102
00:05:45,110 --> 00:05:43,199
going we're then going to deploy the

103
00:05:46,629 --> 00:05:45,120
remote sensing mass so we can take these

104
00:05:48,150 --> 00:05:46,639
beautiful panoramas that we've all been

105
00:05:49,909 --> 00:05:48,160
waiting to see

106
00:05:50,870 --> 00:05:49,919
but as for now the first order of

107
00:05:52,870 --> 00:05:50,880
business is make sure that our

108
00:05:54,950 --> 00:05:52,880
communications to the earth are healthy

109
00:05:56,870 --> 00:05:54,960
and that's the prime activity for uh

110
00:05:59,430 --> 00:05:56,880
upcoming for today

111
00:06:01,430 --> 00:05:59,440
but last night we got one other um

112
00:06:04,550 --> 00:06:01,440
beautiful piece of information and that

113
00:06:08,230 --> 00:06:04,560
is a haz cam image now our haz cams we

114
00:06:09,749 --> 00:06:08,240
saw them um last night during during edl

115
00:06:11,670 --> 00:06:09,759
these are little cameras that point

116
00:06:14,150 --> 00:06:11,680
mostly at our wheels and at the ground

117
00:06:15,670 --> 00:06:14,160
in front of us in the front and the back

118
00:06:16,710 --> 00:06:15,680
and when we land we're concerned that

119
00:06:18,309 --> 00:06:16,720
they're going that we're going to kick

120
00:06:20,390 --> 00:06:18,319
up some dust right we're firing rockets

121
00:06:22,550 --> 00:06:20,400
and we might be throwing up a plume of

122
00:06:24,390 --> 00:06:22,560
dust and so we have little clear covers

123
00:06:26,629 --> 00:06:24,400
on them and those are the images that we

124
00:06:27,909 --> 00:06:26,639
got um last night at landing the very

125
00:06:29,189 --> 00:06:27,919
first things that we were clapping about

126
00:06:31,029 --> 00:06:29,199
in the in the control room so if you

127
00:06:32,550 --> 00:06:31,039
could show the first graphic

128
00:06:34,390 --> 00:06:32,560
this is that picture

129
00:06:36,070 --> 00:06:34,400
so now that we're all

130
00:06:37,909 --> 00:06:36,080
you know awake and we've digested this

131
00:06:39,430 --> 00:06:37,919
and we have a little bit less adrenaline

132
00:06:41,749 --> 00:06:39,440
that it's not such a great picture

133
00:06:43,830 --> 00:06:41,759
anymore right right it's beautiful it's

134
00:06:45,670 --> 00:06:43,840
beautiful to us right it's beautiful to

135
00:06:47,270 --> 00:06:45,680
us because of what it means but you can

136
00:06:48,550 --> 00:06:47,280
see uh there's a lot of stuff on the

137
00:06:50,469 --> 00:06:48,560
lens there

138
00:06:52,390 --> 00:06:50,479
and that is actually dust kicked up by

139
00:06:54,309 --> 00:06:52,400
by the landing event

140
00:06:55,430 --> 00:06:54,319
so we want to get rid of those covers uh

141
00:06:58,070 --> 00:06:55,440
you can see our beautiful shadow there

142
00:06:59,990 --> 00:06:58,080
and we and we uh we love that we hoped

143
00:07:01,830 --> 00:07:00,000
to get the rear

144
00:07:03,589 --> 00:07:01,840
and the front down this is a front haz

145
00:07:05,189 --> 00:07:03,599
cam the sun's behind us and you can see

146
00:07:07,189 --> 00:07:05,199
our shadow there

147
00:07:08,790 --> 00:07:07,199
um but let's go to the let's go to the

148
00:07:10,230 --> 00:07:08,800
next let's go to the animation and and

149
00:07:11,670 --> 00:07:10,240
show that remind you where these haz

150
00:07:13,990 --> 00:07:11,680
cams are and what you're about to see in

151
00:07:15,029 --> 00:07:14,000
the next image and uh and and the cover

152
00:07:16,629 --> 00:07:15,039
deploy

153
00:07:18,309 --> 00:07:16,639
right so they're so they're

154
00:07:20,070 --> 00:07:18,319
looking for mobility hazards right

155
00:07:21,430 --> 00:07:20,080
that's what we call them the haz cams so

156
00:07:22,469 --> 00:07:21,440
there they are kind of pointed at the

157
00:07:24,150 --> 00:07:22,479
ground

158
00:07:25,990 --> 00:07:24,160
and they have a wide field of view kind

159
00:07:27,749 --> 00:07:26,000
of a fisheye type lens okay that's the

160
00:07:29,589 --> 00:07:27,759
cover deploy right

161
00:07:31,909 --> 00:07:29,599
and and there and there are the cameras

162
00:07:32,790 --> 00:07:31,919
so let's go to the next image so last

163
00:07:34,309 --> 00:07:32,800
night

164
00:07:36,230 --> 00:07:34,319
after landing

165
00:07:38,070 --> 00:07:36,240
we fired all of our pyro's released

166
00:07:39,589 --> 00:07:38,080
these covers took these haz-cam images

167
00:07:41,830 --> 00:07:39,599
and these are the things that came down

168
00:07:43,749 --> 00:07:41,840
just before 1am right

169
00:07:46,070 --> 00:07:43,759
here here on the west coast

170
00:07:47,510 --> 00:07:46,080
okay so there there is our image

171
00:07:49,909 --> 00:07:47,520
and we're looking out the back you can

172
00:07:51,990 --> 00:07:49,919
see the the left rear wheel there you

173
00:07:53,350 --> 00:07:52,000
can see a little bit of of that hinge

174
00:07:54,710 --> 00:07:53,360
actually in the field of view there you

175
00:07:57,029 --> 00:07:54,720
see the kind of looks things like a

176
00:07:58,790 --> 00:07:57,039
spring there on the

177
00:08:00,550 --> 00:07:58,800
lower right side of the image

178
00:08:02,950 --> 00:08:00,560
and then on the upper left is part of

179
00:08:04,790 --> 00:08:02,960
the uh the rtg right the power source

180
00:08:06,309 --> 00:08:04,800
that's that's one of the radiator fins

181
00:08:07,430 --> 00:08:06,319
that were clip that we're seeing there

182
00:08:08,950 --> 00:08:07,440
on the side

183
00:08:11,189 --> 00:08:08,960
and uh several of the folks that worked

184
00:08:12,790 --> 00:08:11,199
on on assembling the rover and in atlo

185
00:08:13,990 --> 00:08:12,800
and test said they never got a picture

186
00:08:15,749 --> 00:08:14,000
this good they could never get the

187
00:08:16,629 --> 00:08:15,759
lighting quite right here on the earth

188
00:08:18,469 --> 00:08:16,639
and so

189
00:08:20,309 --> 00:08:18,479
so this is the definitive control image

190
00:08:21,830 --> 00:08:20,319
now of how the rover is supposed to look

191
00:08:23,430 --> 00:08:21,840
uh here on mars

192
00:08:25,350 --> 00:08:23,440
and uh over on the side there you're

193
00:08:27,510 --> 00:08:25,360
gonna see over on the right side you see

194
00:08:29,990 --> 00:08:27,520
some some hills there

195
00:08:31,830 --> 00:08:30,000
over on the on the far edge there and

196
00:08:33,829 --> 00:08:31,840
john grosser is going to show that later

197
00:08:36,070 --> 00:08:33,839
now i personally have to say i i really

198
00:08:37,750 --> 00:08:36,080
love these images because you know later

199
00:08:41,190 --> 00:08:37,760
we're going to get magnificent color

200
00:08:43,190 --> 00:08:41,200
panoramas and 3d images and and

201
00:08:45,030 --> 00:08:43,200
magnificent things on mars

202
00:08:47,670 --> 00:08:45,040
but these first images somehow are

203
00:08:49,350 --> 00:08:47,680
always the best ones to me because when

204
00:08:51,670 --> 00:08:49,360
you land on mars

205
00:08:53,509 --> 00:08:51,680
it's new every time

206
00:08:55,509 --> 00:08:53,519
and these you know this is a new place

207
00:08:57,110 --> 00:08:55,519
on mars you know we go on vacation to

208
00:08:58,870 --> 00:08:57,120
see a different part of the earth it's

209
00:09:00,790 --> 00:08:58,880
on our own planet and here we're seeing

210
00:09:02,150 --> 00:09:00,800
a part of mars we've never seen before

211
00:09:04,150 --> 00:09:02,160
and later you'll see a kind of a zoom in

212
00:09:06,949 --> 00:09:04,160
of that of this uh of this part of uh

213
00:09:08,710 --> 00:09:06,959
gail gail crater's rim here um

214
00:09:10,790 --> 00:09:08,720
and kind of reoriented so it looks more

215
00:09:12,550 --> 00:09:10,800
like like a landscape that we would

216
00:09:13,910 --> 00:09:12,560
recognize on the earth

217
00:09:16,150 --> 00:09:13,920
but we're going to continue to get the

218
00:09:18,389 --> 00:09:16,160
front of the front version of this with

219
00:09:19,990 --> 00:09:18,399
the shadow that we had yesterday out

220
00:09:21,750 --> 00:09:20,000
that same direction will be coming down

221
00:09:22,949 --> 00:09:21,760
later today

222
00:09:25,350 --> 00:09:22,959
and then over the next couple of days

223
00:09:27,030 --> 00:09:25,360
we'll be sending down the the hand lens

224
00:09:28,870 --> 00:09:27,040
imager which is which is in color and

225
00:09:31,430 --> 00:09:28,880
after we get the rsm up

226
00:09:34,150 --> 00:09:31,440
uh we will get some some nice uh black

227
00:09:35,990 --> 00:09:34,160
and white panoramas first

228
00:09:37,829 --> 00:09:36,000
now this is our new home at least for a

229
00:09:39,670 --> 00:09:37,839
while here on gale and we need to

230
00:09:41,430 --> 00:09:39,680
explore it and take a look around and

231
00:09:43,590 --> 00:09:41,440
then of course eventually um head for

232
00:09:45,590 --> 00:09:43,600
the hills now we actually hope in the

233
00:09:47,190 --> 00:09:45,600
front haz cam that should be coming down

234
00:09:49,269 --> 00:09:47,200
in a few hours from here we can actually

235
00:09:50,949 --> 00:09:49,279
see the mountain of gale

236
00:09:54,150 --> 00:09:50,959
we think we're pointed kind of east

237
00:09:56,470 --> 00:09:54,160
southeast about 112 degrees heading

238
00:09:58,790 --> 00:09:56,480
we're at a very slight tilt we are in

239
00:09:59,750 --> 00:09:58,800
fact let me look at it here we are 3.6

240
00:10:01,670 --> 00:09:59,760
degrees

241
00:10:03,350 --> 00:10:01,680
negative in pitch so the front is down

242
00:10:05,110 --> 00:10:03,360
by about 3 degrees

243
00:10:06,069 --> 00:10:05,120
and we are left side down about two

244
00:10:07,750 --> 00:10:06,079
degrees

245
00:10:10,389 --> 00:10:07,760
now those are pretty small numbers we

246
00:10:13,030 --> 00:10:10,399
landed pretty much on this table right

247
00:10:15,750 --> 00:10:13,040
here it's pretty it's pretty flat

248
00:10:16,949 --> 00:10:15,760
uh we're in a pretty good spot here

249
00:10:19,670 --> 00:10:16,959
but there's still the question where

250
00:10:20,790 --> 00:10:19,680
exactly is this spot on our maps of mars

251
00:10:23,590 --> 00:10:20,800
and to talk a little bit about that we

252
00:10:24,550 --> 00:10:23,600
have miguel san martin thank you mike

253
00:10:27,030 --> 00:10:24,560
so

254
00:10:28,069 --> 00:10:27,040
good morning um i hope you have enjoyed

255
00:10:33,030 --> 00:10:28,079
the

256
00:10:34,870 --> 00:10:33,040
i sure did actually i'm i want to get

257
00:10:35,910 --> 00:10:34,880
another round

258
00:10:37,829 --> 00:10:35,920
and um

259
00:10:38,949 --> 00:10:37,839
uh maybe they have to wait a few few

260
00:10:41,670 --> 00:10:38,959
more years

261
00:10:44,790 --> 00:10:41,680
and uh so

262
00:10:46,630 --> 00:10:44,800
the uh edl what looked beautiful from

263
00:10:48,630 --> 00:10:46,640
from our monitors of course we haven't

264
00:10:50,630 --> 00:10:48,640
had the time to look the data carefully

265
00:10:51,430 --> 00:10:50,640
and the data is going to be coming

266
00:10:54,230 --> 00:10:51,440
uh

267
00:10:56,310 --> 00:10:54,240
soon i mean the the right now the rover

268
00:10:58,790 --> 00:10:56,320
is full of edl

269
00:11:01,110 --> 00:10:58,800
the threshold through of edl data that

270
00:11:03,269 --> 00:11:01,120
is going to help us when we download it

271
00:11:05,430 --> 00:11:03,279
understand and bring our knowledge of

272
00:11:08,310 --> 00:11:05,440
edl to even higher levels which is we

273
00:11:09,990 --> 00:11:08,320
are very excited right now the edl team

274
00:11:10,870 --> 00:11:10,000
waiting for that data

275
00:11:12,870 --> 00:11:10,880
so

276
00:11:15,910 --> 00:11:12,880
i'm going to talk to you about our best

277
00:11:18,389 --> 00:11:15,920
knowledge right now of where we landed

278
00:11:20,870 --> 00:11:18,399
okay it's not that might change when we

279
00:11:24,550 --> 00:11:20,880
get high-rise data but this is what we

280
00:11:26,710 --> 00:11:24,560
know the the best at this point so uh

281
00:11:28,550 --> 00:11:26,720
next picture i don't know

282
00:11:31,430 --> 00:11:28,560
okay where uh

283
00:11:33,269 --> 00:11:31,440
we did land inside the crater so

284
00:11:35,430 --> 00:11:33,279
we know that

285
00:11:37,269 --> 00:11:35,440
and uh you can see there the uh our

286
00:11:40,470 --> 00:11:37,279
landing ellipse 20 kilometers by seven

287
00:11:44,710 --> 00:11:40,480
kilometers and uh and uh so we can if we

288
00:11:46,870 --> 00:11:44,720
can get the next uh picture please

289
00:11:49,670 --> 00:11:46,880
and there's the dot or where we think we

290
00:11:51,750 --> 00:11:49,680
landed this is two kilometers uh east of

291
00:11:52,629 --> 00:11:51,760
the landing of the center of the landing

292
00:11:55,990 --> 00:11:52,639
site

293
00:11:57,910 --> 00:11:56,000
uh of the aim point and about uh it's a

294
00:11:59,990 --> 00:11:57,920
few hundred meters north now let me

295
00:12:01,990 --> 00:12:00,000
explain to you where we get that that

296
00:12:04,550 --> 00:12:02,000
that estimate from okay

297
00:12:06,150 --> 00:12:04,560
uh this estimate is based on

298
00:12:08,629 --> 00:12:06,160
uh ground

299
00:12:10,629 --> 00:12:08,639
uh navigation the navigation down here

300
00:12:13,190 --> 00:12:10,639
on the ground by the navigation team

301
00:12:13,910 --> 00:12:13,200
that thomas martin murders

302
00:12:15,190 --> 00:12:13,920
and

303
00:12:17,750 --> 00:12:15,200
leads that

304
00:12:19,750 --> 00:12:17,760
as you saw yesterday gave us tremendous

305
00:12:21,030 --> 00:12:19,760
incredible precision in navigation that

306
00:12:24,069 --> 00:12:21,040
we seeded

307
00:12:25,110 --> 00:12:24,079
the the navigation software of curiosity

308
00:12:27,269 --> 00:12:25,120
with that

309
00:12:29,430 --> 00:12:27,279
very precise data and then curiosity

310
00:12:31,509 --> 00:12:29,440
uses using its own navigation

311
00:12:33,190 --> 00:12:31,519
instruments in particular

312
00:12:35,030 --> 00:12:33,200
what we call an inertial measurement

313
00:12:37,350 --> 00:12:35,040
unit which is a

314
00:12:38,550 --> 00:12:37,360
it's a relative instrument that can take

315
00:12:40,870 --> 00:12:38,560
an initial

316
00:12:44,870 --> 00:12:42,949
seed of what the position of velocity is

317
00:12:46,470 --> 00:12:44,880
and it can propagate forward

318
00:12:47,670 --> 00:12:46,480
as it measures all the forces being

319
00:12:50,550 --> 00:12:47,680
applied to the spacecraft by the

320
00:12:52,470 --> 00:12:50,560
atmosphere and its own rockets

321
00:12:55,509 --> 00:12:52,480
so it can but but it is kind of a dead

322
00:12:57,910 --> 00:12:55,519
reckoning so it's kind of uh kind of

323
00:12:59,910 --> 00:12:57,920
like the odometer in a car counting

324
00:13:03,269 --> 00:12:59,920
wheels okay so this it tends to

325
00:13:04,829 --> 00:13:03,279
accumulate error okay so um

326
00:13:08,389 --> 00:13:04,839
but

327
00:13:10,870 --> 00:13:08,399
that's so this in essence that point is

328
00:13:12,310 --> 00:13:10,880
based on the one of the last evrs the

329
00:13:14,150 --> 00:13:12,320
last piece of telemetry that the

330
00:13:16,629 --> 00:13:14,160
spacecraft told us when he touched down

331
00:13:18,310 --> 00:13:16,639
says i touched down and this is where we

332
00:13:19,350 --> 00:13:18,320
are very confident the spacecraft tells

333
00:13:21,509 --> 00:13:19,360
you that

334
00:13:23,670 --> 00:13:21,519
and then uh obviously we need to analyze

335
00:13:25,670 --> 00:13:23,680
it and and that's the point with some

336
00:13:28,550 --> 00:13:25,680
corrections that we did with our friends

337
00:13:30,710 --> 00:13:28,560
at langley uh based on

338
00:13:33,030 --> 00:13:30,720
some technicalities that probably uh we

339
00:13:36,310 --> 00:13:33,040
shouldn't get into

340
00:13:39,189 --> 00:13:36,320
so uh but i you know we we actually

341
00:13:40,790 --> 00:13:39,199
get other indications from from the data

342
00:13:42,150 --> 00:13:40,800
that we saw in the telemetry that gives

343
00:13:45,189 --> 00:13:42,160
us the impression that we actually did

344
00:13:47,430 --> 00:13:45,199
very well like for example one sanity

345
00:13:48,389 --> 00:13:47,440
check that we do is that eventually

346
00:13:50,230 --> 00:13:48,399
after

347
00:13:52,949 --> 00:13:50,240
propagating

348
00:13:53,750 --> 00:13:52,959
with the inertial measurement unit

349
00:13:58,230 --> 00:13:53,760
for

350
00:13:59,750 --> 00:13:58,240
eventually we remove the the heat shield

351
00:14:00,710 --> 00:13:59,760
and the radar starts looking at the

352
00:14:03,110 --> 00:14:00,720
ground

353
00:14:05,350 --> 00:14:03,120
and now we can see how well in some

354
00:14:08,870 --> 00:14:05,360
aspects the inertial measurement unit

355
00:14:10,150 --> 00:14:08,880
did and how well thomas thomas did okay

356
00:14:12,389 --> 00:14:10,160
because it gives us altitude and

357
00:14:13,590 --> 00:14:12,399
velocity relative to the ground

358
00:14:15,509 --> 00:14:13,600
and actually

359
00:14:17,670 --> 00:14:15,519
they agree tremendously well is with it

360
00:14:19,189 --> 00:14:17,680
i mean it's just so well that it's we

361
00:14:20,790 --> 00:14:19,199
have to look at the data again because

362
00:14:23,110 --> 00:14:20,800
it's hard to believe we haven't been

363
00:14:25,509 --> 00:14:23,120
able to get our simulations to work that

364
00:14:28,150 --> 00:14:25,519
well and i'm not and i'm seriously

365
00:14:30,710 --> 00:14:28,160
yeah it was a correction of a few meters

366
00:14:33,350 --> 00:14:30,720
in altitude and in velocity less than a

367
00:14:34,230 --> 00:14:33,360
meter per second okay and by the way and

368
00:14:39,750 --> 00:14:34,240
that

369
00:14:42,230 --> 00:14:39,760
we did how good was our last attitude

370
00:14:43,189 --> 00:14:42,240
fix based on the stars okay just like

371
00:14:45,829 --> 00:14:43,199
the old

372
00:14:47,509 --> 00:14:45,839
uh sailors did we still use the stars

373
00:14:49,750 --> 00:14:47,519
and i think that's great i mean it

374
00:14:51,910 --> 00:14:49,760
connects us with the past so we did the

375
00:14:55,269 --> 00:14:51,920
final looks at the stars we figure out

376
00:14:57,590 --> 00:14:55,279
the curiosity did that all on itself

377
00:14:59,750 --> 00:14:57,600
looked at the stars took the navigation

378
00:15:02,150 --> 00:14:59,760
data from the ground and then he took it

379
00:15:03,990 --> 00:15:02,160
all the way down and uh and guided the

380
00:15:05,750 --> 00:15:04,000
spacecraft and and that's the best

381
00:15:08,230 --> 00:15:05,760
knowledge of where we are

382
00:15:10,870 --> 00:15:08,240
uh we think that within a kilometer is

383
00:15:13,750 --> 00:15:10,880
our estimate uh

384
00:15:15,670 --> 00:15:13,760
but um

385
00:15:18,550 --> 00:15:15,680
you know we have to wait for precise

386
00:15:20,710 --> 00:15:18,560
localization by high rise so

387
00:15:21,430 --> 00:15:20,720
that's that's all i have to say thank

388
00:15:23,590 --> 00:15:21,440
you

389
00:15:26,870 --> 00:15:23,600
sarah

390
00:15:28,230 --> 00:15:26,880
so speaking of high-rise um

391
00:15:31,829 --> 00:15:28,240
we heard a lot we've heard you've heard

392
00:15:34,389 --> 00:15:31,839
a lot about how odyssey was listening to

393
00:15:36,230 --> 00:15:34,399
msl as it came in for landing but

394
00:15:37,430 --> 00:15:36,240
odyssey wasn't the only orbiter there

395
00:15:39,509 --> 00:15:37,440
listening

396
00:15:41,110 --> 00:15:39,519
mars reconnaissance orbiter was also

397
00:15:43,189 --> 00:15:41,120
there and

398
00:15:46,629 --> 00:15:43,199
mro wasn't just listening we were

399
00:15:49,670 --> 00:15:46,639
watching so the high-rise camera is one

400
00:15:51,430 --> 00:15:49,680
of the cameras on mro and we normally

401
00:15:54,550 --> 00:15:51,440
take pictures of the surface and we can

402
00:15:56,790 --> 00:15:54,560
get pictures up to resolutions of 30

403
00:16:00,550 --> 00:15:56,800
centimeters per pixel which is just

404
00:16:04,069 --> 00:16:00,560
really fantastic but um what we did this

405
00:16:06,870 --> 00:16:04,079
time if you can go to the graphic

406
00:16:10,230 --> 00:16:06,880
there's mro coming along and we actually

407
00:16:12,230 --> 00:16:10,240
took a picture with highrise as msl came

408
00:16:14,470 --> 00:16:12,240
in on the parachute so you can see the

409
00:16:17,110 --> 00:16:14,480
little dot there is msl moving across

410
00:16:19,670 --> 00:16:17,120
the box shows our image there's the

411
00:16:21,030 --> 00:16:19,680
parachute

412
00:16:23,350 --> 00:16:21,040
and

413
00:16:37,590 --> 00:16:23,360
if we zoom in

414
00:16:41,430 --> 00:16:38,550
so i

415
00:16:43,829 --> 00:16:41,440
and this is really a testament to uh the

416
00:16:45,509 --> 00:16:43,839
the high-rise team uh alfred mcewen the

417
00:16:47,910 --> 00:16:45,519
principal investigator and the highrise

418
00:16:50,629 --> 00:16:47,920
operations team at university of arizona

419
00:16:52,310 --> 00:16:50,639
and the mro spacecraft team

420
00:16:53,990 --> 00:16:52,320
this was really

421
00:16:56,310 --> 00:16:54,000
we've been working on putting this

422
00:16:58,230 --> 00:16:56,320
imaging sequence together since about

423
00:17:00,470 --> 00:16:58,240
march we've been tweaking it and

424
00:17:02,230 --> 00:17:00,480
updating it as msl has been getting

425
00:17:05,429 --> 00:17:02,240
closer and closer to mars but the final

426
00:17:06,630 --> 00:17:05,439
commands were sent up a couple days ago

427
00:17:09,590 --> 00:17:06,640
and

428
00:17:11,669 --> 00:17:09,600
this image was taken six minutes after

429
00:17:12,870 --> 00:17:11,679
msl entered the

430
00:17:17,510 --> 00:17:12,880
atmosphere

431
00:17:19,750 --> 00:17:17,520
and mro was about 340 kilometers away

432
00:17:20,789 --> 00:17:19,760
from msl at the time the picture was

433
00:17:22,150 --> 00:17:20,799
taken

434
00:17:29,350 --> 00:17:22,160
you can see

435
00:17:30,950 --> 00:17:29,360
the the hole in the top there um the

436
00:17:33,590 --> 00:17:30,960
that inset image

437
00:17:35,590 --> 00:17:33,600
is been stretched different differently

438
00:17:37,990 --> 00:17:35,600
so that you can see

439
00:17:42,070 --> 00:17:38,000
the um you can see the parachute clearly

440
00:17:46,070 --> 00:17:44,390
and let's see if we go i think that's i

441
00:17:48,230 --> 00:17:46,080
think that's the last one or we can go

442
00:17:51,350 --> 00:17:48,240
to the last one

443
00:17:55,270 --> 00:17:51,360
so yes so this is we have taken highrise

444
00:17:57,590 --> 00:17:55,280
has taken over 120 pictures of gale as

445
00:18:00,070 --> 00:17:57,600
part of the landing site selection and

446
00:18:02,630 --> 00:18:00,080
characterization process but i really

447
00:18:05,029 --> 00:18:02,640
think this is the coolest one

448
00:18:06,789 --> 00:18:05,039
so um and so now

449
00:18:07,990 --> 00:18:06,799
john is going to talk about what we see

450
00:18:09,110 --> 00:18:08,000
on the surface

451
00:18:11,510 --> 00:18:09,120
thanks sarah

452
00:18:13,909 --> 00:18:11,520
okay so um let's just go to the first

453
00:18:16,470 --> 00:18:13,919
graphic right away please and get you

454
00:18:18,630 --> 00:18:16,480
back into the has cams

455
00:18:21,990 --> 00:18:18,640
tell you a little bit about that uh

456
00:18:24,870 --> 00:18:22,000
here's a image our sort of standard uh

457
00:18:29,029 --> 00:18:24,880
color viking era color superimposed on

458
00:18:31,750 --> 00:18:29,039
top of a ctx dem and showing the

459
00:18:33,590 --> 00:18:31,760
topography of gale crater

460
00:18:35,830 --> 00:18:33,600
you can see the well-defined crater rim

461
00:18:37,909 --> 00:18:35,840
there the landing ellipse and uh and

462
00:18:39,909 --> 00:18:37,919
mount sharp towards the middle

463
00:18:41,990 --> 00:18:39,919
and to help you understand what we're

464
00:18:42,950 --> 00:18:42,000
going to be seeing in the in the haz

465
00:18:45,110 --> 00:18:42,960
cams

466
00:18:47,830 --> 00:18:45,120
let's just get oriented a little bit

467
00:18:50,830 --> 00:18:47,840
so north is up here towards the top of

468
00:18:53,909 --> 00:18:50,840
the image and therefore if you go

469
00:18:56,950 --> 00:18:53,919
counterclockwise that takes you in into

470
00:18:58,470 --> 00:18:56,960
the the northwest uh quadrant

471
00:19:01,430 --> 00:18:58,480
and uh

472
00:19:03,190 --> 00:19:01,440
uh and there you see the rim so

473
00:19:04,950 --> 00:19:03,200
uh the northern rim

474
00:19:07,430 --> 00:19:04,960
of of gale crater is actually

475
00:19:10,390 --> 00:19:07,440
considerably lower in elevation than the

476
00:19:12,230 --> 00:19:10,400
than the summit of of mount sharp and

477
00:19:14,230 --> 00:19:12,240
you can even see where the

478
00:19:15,190 --> 00:19:14,240
the rim is is breached a little bit

479
00:19:16,070 --> 00:19:15,200
there

480
00:19:17,909 --> 00:19:16,080
and

481
00:19:19,110 --> 00:19:17,919
but remember the topography remember the

482
00:19:20,789 --> 00:19:19,120
topography of the rim you're gonna have

483
00:19:24,070 --> 00:19:20,799
to keep that in mind

484
00:19:26,789 --> 00:19:24,080
and uh and then mount sharp itself

485
00:19:27,909 --> 00:19:26,799
is also going to represent a topographic

486
00:19:29,669 --> 00:19:27,919
rise

487
00:19:32,710 --> 00:19:29,679
and as mike mentioned

488
00:19:35,990 --> 00:19:32,720
before the spacecraft is oriented

489
00:19:39,669 --> 00:19:36,000
northwest southeast pointing forward

490
00:19:41,430 --> 00:19:39,679
towards mount sharp and uh so if we go

491
00:19:44,150 --> 00:19:41,440
to the next image

492
00:19:46,789 --> 00:19:44,160
this is really spectacular uh what's

493
00:19:49,830 --> 00:19:46,799
happened here is uh justin mackey and

494
00:19:51,990 --> 00:19:49,840
bob dean worked to take the the has cam

495
00:19:54,789 --> 00:19:52,000
image remember this camera has a fisheye

496
00:19:56,549 --> 00:19:54,799
lens so there's a lot of distortion uh

497
00:19:57,750 --> 00:19:56,559
due to the curve extreme curvature of

498
00:19:59,909 --> 00:19:57,760
the lens

499
00:20:01,669 --> 00:19:59,919
and by restoring that you go back to the

500
00:20:03,750 --> 00:20:01,679
horizontal here so this would be the

501
00:20:06,470 --> 00:20:03,760
view that you saw you would see if you

502
00:20:09,190 --> 00:20:06,480
were a haz cam on the surface of mars

503
00:20:11,430 --> 00:20:09,200
and there we are looking rear has cam

504
00:20:13,270 --> 00:20:11,440
towards the rim of gale crater

505
00:20:15,270 --> 00:20:13,280
and uh and this couldn't have been a

506
00:20:17,590 --> 00:20:15,280
better position to land in

507
00:20:19,350 --> 00:20:17,600
because we get to see rearwards and

508
00:20:20,870 --> 00:20:19,360
forwards and in this view you see the

509
00:20:23,590 --> 00:20:20,880
rim of the gale crater you've heard us

510
00:20:25,750 --> 00:20:23,600
speaking about the alluvial fan

511
00:20:28,390 --> 00:20:25,760
that we think we've landed very close to

512
00:20:30,789 --> 00:20:28,400
the end of and this is the source area

513
00:20:33,510 --> 00:20:30,799
so this is bringing materials in from

514
00:20:35,110 --> 00:20:33,520
the rim which is not our destination

515
00:20:36,630 --> 00:20:35,120
uh but we're getting a free sample

516
00:20:38,230 --> 00:20:36,640
without having to drive over there

517
00:20:40,390 --> 00:20:38,240
potentially if we're able to drive the

518
00:20:43,029 --> 00:20:40,400
rover and and discover the right kind of

519
00:20:45,909 --> 00:20:43,039
geology that really could represent uh

520
00:20:48,390 --> 00:20:45,919
the distal part of this alluvial fan

521
00:20:50,230 --> 00:20:48,400
and in the foreground you see a scene

522
00:20:52,470 --> 00:20:50,240
that's that's very familiar to you from

523
00:20:55,590 --> 00:20:52,480
other images of mars uh what is

524
00:20:57,750 --> 00:20:55,600
undoubtedly a wind-swept plane uh with

525
00:20:59,909 --> 00:20:57,760
coarse fragments left behind the science

526
00:21:01,830 --> 00:20:59,919
team is initially impressed by

527
00:21:04,549 --> 00:21:01,840
the rather uniform grain size

528
00:21:07,190 --> 00:21:04,559
distribution of the coarser particles

529
00:21:09,909 --> 00:21:07,200
uh we don't yet know what uh what that

530
00:21:11,669 --> 00:21:09,919
uh what that diameter is but you can get

531
00:21:13,510 --> 00:21:11,679
the sense qualitatively that there's a

532
00:21:17,750 --> 00:21:13,520
bunch of particles there that are about

533
00:21:19,430 --> 00:21:17,760
the about the same size so in the in the

534
00:21:21,350 --> 00:21:19,440
upcoming saul's we're going to be

535
00:21:23,270 --> 00:21:21,360
debating this and discussing it and

536
00:21:24,789 --> 00:21:23,280
trying to figure out uh where to go on

537
00:21:26,070 --> 00:21:24,799
what to do but this will be part of the

538
00:21:27,990 --> 00:21:26,080
story

539
00:21:29,669 --> 00:21:28,000
a target like this is interesting

540
00:21:31,350 --> 00:21:29,679
scientifically because one of the things

541
00:21:33,669 --> 00:21:31,360
that we're going to want to do after the

542
00:21:36,549 --> 00:21:33,679
commissioning period is over is scoop up

543
00:21:38,390 --> 00:21:36,559
some of the soil and analyze it and what

544
00:21:39,510 --> 00:21:38,400
we would really like to do is analyze

545
00:21:41,669 --> 00:21:39,520
something that we feel is very

546
00:21:44,230 --> 00:21:41,679
representative of mars so something like

547
00:21:47,190 --> 00:21:44,240
this is potentially a target for us to

548
00:21:49,830 --> 00:21:47,200
think about and by sampling it and and

549
00:21:52,390 --> 00:21:49,840
measuring it uh we then have a sample of

550
00:21:55,590 --> 00:21:52,400
what could be the most global uh sample

551
00:21:58,390 --> 00:21:55,600
of mars that uh we could measure

552
00:22:01,270 --> 00:21:58,400
okay now in the next one this one's

553
00:22:03,029 --> 00:22:01,280
tough okay this one uh i think the edl

554
00:22:04,789 --> 00:22:03,039
guys were probably seeing a vision like

555
00:22:07,029 --> 00:22:04,799
this a few hours ago

556
00:22:09,270 --> 00:22:07,039
but uh what you can see now again

557
00:22:11,990 --> 00:22:09,280
remember the curvature is taken out

558
00:22:14,230 --> 00:22:12,000
we are looking towards the southeast uh

559
00:22:15,830 --> 00:22:14,240
you've got the shadow of the rover there

560
00:22:17,830 --> 00:22:15,840
and this was the first indication that

561
00:22:20,310 --> 00:22:17,840
we were looking southeast because the

562
00:22:21,430 --> 00:22:20,320
the sun was setting behind us

563
00:22:23,669 --> 00:22:21,440
and

564
00:22:25,669 --> 00:22:23,679
uh gosh i just realized i forgot to

565
00:22:28,310 --> 00:22:25,679
point something up this is important is

566
00:22:36,310 --> 00:22:28,320
it possible to go backwards

567
00:22:39,830 --> 00:22:38,390
one more please there we go okay so look

568
00:22:42,710 --> 00:22:39,840
at the landing ellipse if you go to the

569
00:22:44,310 --> 00:22:42,720
southwest part notice that black line

570
00:22:46,470 --> 00:22:44,320
that that goes from northeast to

571
00:22:49,830 --> 00:22:46,480
southwest through that that's this dune

572
00:22:50,950 --> 00:22:49,840
field which lies at the base of of mount

573
00:22:53,350 --> 00:22:50,960
sharp there

574
00:22:54,630 --> 00:22:53,360
uh we this is beautiful and all the

575
00:22:55,669 --> 00:22:54,640
high-rise images that have been

576
00:22:57,270 --> 00:22:55,679
collected

577
00:22:59,909 --> 00:22:57,280
and so that black line is going to be

578
00:23:02,230 --> 00:22:59,919
our frame of reference and and as miguel

579
00:23:04,710 --> 00:23:02,240
showed we have landed somewhere to the

580
00:23:06,470 --> 00:23:04,720
north of that black line in the ellipse

581
00:23:08,549 --> 00:23:06,480
and in the haz cam image we're looking

582
00:23:11,190 --> 00:23:08,559
towards the base of mount sharp so now

583
00:23:13,750 --> 00:23:11,200
let's advance two again there we are

584
00:23:15,510 --> 00:23:13,760
right on the money that black line about

585
00:23:18,149 --> 00:23:15,520
three quarters of the way up there we

586
00:23:21,350 --> 00:23:18,159
believe is the dune field that black

587
00:23:22,470 --> 00:23:21,360
line of dunes and therefore as you work

588
00:23:24,870 --> 00:23:22,480
upwards

589
00:23:26,630 --> 00:23:24,880
in the image very fuzzy in there we

590
00:23:29,669 --> 00:23:26,640
believe you see the outline of mount

591
00:23:31,669 --> 00:23:29,679
sharp itself bright in the setting sun

592
00:23:33,430 --> 00:23:31,679
and and the upper part then is the

593
00:23:35,830 --> 00:23:33,440
horizon in the sky which would look

594
00:23:38,470 --> 00:23:35,840
darker so you should see a slope which

595
00:23:41,029 --> 00:23:38,480
goes from above that that black line of

596
00:23:43,750 --> 00:23:41,039
dunes sloping to the upper right and

597
00:23:45,990 --> 00:23:43,760
separating light below from dark above

598
00:23:48,149 --> 00:23:46,000
and we believe that's the silhouette of

599
00:23:50,070 --> 00:23:48,159
of mount sharp and the setting sun

600
00:23:51,909 --> 00:23:50,080
so you have a little bit of adventure

601
00:23:54,390 --> 00:23:51,919
before you i'll be sleeping when the

602
00:23:56,390 --> 00:23:54,400
next downlink occurs and uh

603
00:23:58,390 --> 00:23:56,400
uh joy crisp will be able to talk to you

604
00:24:00,390 --> 00:23:58,400
about the the the data that will get

605
00:24:02,549 --> 00:24:00,400
down that will be without the dust cover

606
00:24:05,029 --> 00:24:02,559
and uh and higher resolution possibly

607
00:24:07,110 --> 00:24:05,039
even full frame to confirm this but we

608
00:24:09,590 --> 00:24:07,120
think we've landed and the haz cams are

609
00:24:12,390 --> 00:24:09,600
picking up the topography on on opposing

610
00:24:13,909 --> 00:24:12,400
sides of our landing ellipse

611
00:24:15,669 --> 00:24:13,919
so that's it for me

612
00:24:17,590 --> 00:24:15,679
okay that means we'll open it up to

613
00:24:19,669 --> 00:24:17,600
questions now and we'll get a microphone

614
00:24:21,190 --> 00:24:19,679
to you and i am going to try to memorize

615
00:24:22,549 --> 00:24:21,200
the order in which i see hands come up

616
00:24:24,630 --> 00:24:22,559
and we'll start over here on this side

617
00:24:26,710 --> 00:24:24,640
and work our way over thank you really

618
00:24:28,549 --> 00:24:26,720
kelly beatty sky and telescope uh mike

619
00:24:29,750 --> 00:24:28,559
could you refine the landing time as

620
00:24:31,830 --> 00:24:29,760
best you know it for us i was a little

621
00:24:33,470 --> 00:24:31,840
confused by a time stamp in miguel's

622
00:24:35,430 --> 00:24:33,480
image which said

623
00:24:37,269 --> 00:24:35,440
22-38-50 so

624
00:24:39,990 --> 00:24:37,279
uh what was the landing time as best you

625
00:24:44,230 --> 00:24:40,000
know um i will actually have to get that

626
00:24:48,149 --> 00:24:46,390
no no no no we'll get it we'll get it

627
00:24:53,830 --> 00:24:48,159
for you rob do you know

628
00:25:00,070 --> 00:24:57,430
scott gold at the los angeles times um

629
00:25:02,149 --> 00:25:00,080
can you explain what's just south of the

630
00:25:04,149 --> 00:25:02,159
of the landing site it looks like that

631
00:25:07,190 --> 00:25:04,159
might be the dune area that you've been

632
00:25:08,070 --> 00:25:07,200
talking about and also in in lay terms

633
00:25:10,549 --> 00:25:08,080
how

634
00:25:13,669 --> 00:25:10,559
far are you from what you might consider

635
00:25:16,230 --> 00:25:13,679
to be the foothills of mount sharp

636
00:25:19,110 --> 00:25:16,240
john you want to talk about the dunes uh

637
00:25:21,269 --> 00:25:19,120
sure um the uh you know the dunes that

638
00:25:22,230 --> 00:25:21,279
you see there is uh is a rather narrow

639
00:25:24,870 --> 00:25:22,240
strip

640
00:25:26,950 --> 00:25:24,880
and uh you see it slicing there through

641
00:25:29,990 --> 00:25:26,960
the the southwest part of the landing

642
00:25:32,230 --> 00:25:30,000
ellipse and and so from where we think

643
00:25:34,710 --> 00:25:32,240
we've landed to those dunes is is a

644
00:25:38,070 --> 00:25:34,720
matter of kilometers a few kilometers

645
00:25:40,710 --> 00:25:38,080
away the the basal topography uh where

646
00:25:42,710 --> 00:25:40,720
it really starts to steepen up there

647
00:25:45,590 --> 00:25:42,720
where we would like to access it could

648
00:25:48,070 --> 00:25:45,600
be as much as as 10 kilometers away but

649
00:25:49,350 --> 00:25:48,080
if as the cl as the crow flies directly

650
00:25:51,029 --> 00:25:49,360
towards it would be a much shorter

651
00:25:53,029 --> 00:25:51,039
distance because of that angle that you

652
00:25:56,230 --> 00:25:53,039
see there slicing through the

653
00:25:57,909 --> 00:25:56,240
through the landing ellipse

654
00:26:00,549 --> 00:25:57,919
oh then hand back the mic please thank

655
00:26:01,990 --> 00:26:00,559
you so does that mean that uh to

656
00:26:03,990 --> 00:26:02,000
eventually get to the mountain you would

657
00:26:05,830 --> 00:26:04,000
go north and around the dunes or are

658
00:26:08,470 --> 00:26:05,840
there uh is there anything is there any

659
00:26:09,430 --> 00:26:08,480
reason you can't essentially go straight

660
00:26:11,269 --> 00:26:09,440
um

661
00:26:12,789 --> 00:26:11,279
well it would it uh

662
00:26:14,549 --> 00:26:12,799
you know we would never want to just

663
00:26:16,470 --> 00:26:14,559
drive across the dunes as the the

664
00:26:18,070 --> 00:26:16,480
shortest way to go there we have been

665
00:26:19,830 --> 00:26:18,080
studying them we have this beautiful

666
00:26:22,789 --> 00:26:19,840
topography because of the high-rise

667
00:26:24,789 --> 00:26:22,799
camera and and you know meter scale

668
00:26:26,630 --> 00:26:24,799
uh digital elevation models and so we

669
00:26:28,870 --> 00:26:26,640
study those to find the paths that would

670
00:26:30,149 --> 00:26:28,880
give us the least resistance through it

671
00:26:31,510 --> 00:26:30,159
but really what's going to happen first

672
00:26:33,510 --> 00:26:31,520
is the science team is going to look at

673
00:26:35,750 --> 00:26:33,520
the geology of the landing ellipse as a

674
00:26:37,990 --> 00:26:35,760
whole and then try to find a root and if

675
00:26:39,669 --> 00:26:38,000
it's a more circuitous route if the

676
00:26:42,310 --> 00:26:39,679
science justifies it we will happily

677
00:26:44,230 --> 00:26:42,320
take that route

678
00:26:46,950 --> 00:26:44,240
okay we're going over on this side

679
00:26:48,950 --> 00:26:46,960
right there and we'll go to your next

680
00:26:50,710 --> 00:26:48,960
sorry ian thompson from the register can

681
00:26:52,789 --> 00:26:50,720
you tell me what's actually happened to

682
00:26:53,430 --> 00:26:52,799
the lander which lowered curiosity down

683
00:26:58,470 --> 00:26:53,440
it

684
00:27:00,470 --> 00:26:58,480
direction have you got any information

685
00:27:03,350 --> 00:27:00,480
how far is it how far away it is what

686
00:27:04,789 --> 00:27:03,360
kind of condition it's in

687
00:27:07,190 --> 00:27:04,799
where do i take that

688
00:27:10,390 --> 00:27:07,200
well it's it's it flies away it has

689
00:27:12,149 --> 00:27:10,400
actually a a close-loop algorithm it you

690
00:27:13,269 --> 00:27:12,159
know very rudimentary it doesn't need to

691
00:27:15,350 --> 00:27:13,279
be very

692
00:27:19,110 --> 00:27:15,360
sophisticated because we only we want to

693
00:27:20,789 --> 00:27:19,120
crash it far away 400 meters away and we

694
00:27:21,590 --> 00:27:20,799
we do tell it a heading

695
00:27:23,830 --> 00:27:21,600
okay

696
00:27:25,830 --> 00:27:23,840
uh so we told it to go essentially

697
00:27:28,389 --> 00:27:25,840
towards the north

698
00:27:30,310 --> 00:27:28,399
and where it is but we always we don't

699
00:27:32,470 --> 00:27:30,320
have telemetry that part of that mission

700
00:27:33,430 --> 00:27:32,480
so we don't know so we the only way that

701
00:27:35,430 --> 00:27:33,440
we're gonna find out is through

702
00:27:38,549 --> 00:27:35,440
high-rise

703
00:27:40,149 --> 00:27:38,559
you know taking an image so

704
00:27:41,750 --> 00:27:40,159
but you know we think it's going to be

705
00:27:45,029 --> 00:27:41,760
hundreds of meters it's designed to do

706
00:27:49,669 --> 00:27:47,909
okay go ahead hi eric hand with nature

707
00:27:51,190 --> 00:27:49,679
questions for sarah

708
00:27:52,950 --> 00:27:51,200
so you estimate that this was six

709
00:27:54,549 --> 00:27:52,960
minutes after entry so about a minute

710
00:27:55,990 --> 00:27:54,559
before landing

711
00:27:59,190 --> 00:27:56,000
um

712
00:27:59,990 --> 00:27:59,200
that's after the heat shield uh popped

713
00:28:01,669 --> 00:28:00,000
off

714
00:28:05,190 --> 00:28:01,679
have you looked for that

715
00:28:05,990 --> 00:28:05,200
any sign of that in the image

716
00:28:08,870 --> 00:28:06,000
uh

717
00:28:10,789 --> 00:28:08,880
no we haven't looked for that in in this

718
00:28:12,710 --> 00:28:10,799
image um

719
00:28:16,870 --> 00:28:12,720
i don't think

720
00:28:18,230 --> 00:28:16,880
we'd be able to see it in this image i'm

721
00:28:21,669 --> 00:28:18,240
not sure

722
00:28:23,029 --> 00:28:21,679
we will be taking images

723
00:28:24,070 --> 00:28:23,039
of the landing

724
00:28:26,710 --> 00:28:24,080
site

725
00:28:29,190 --> 00:28:26,720
in the days to come the we might be

726
00:28:30,789 --> 00:28:29,200
taking an image within the next day but

727
00:28:32,070 --> 00:28:30,799
we're definitely taking that one would

728
00:28:34,470 --> 00:28:32,080
be

729
00:28:36,149 --> 00:28:34,480
a little hazy it's but the the we're

730
00:28:38,710 --> 00:28:36,159
taking a very good image

731
00:28:41,029 --> 00:28:38,720
six days from now uh and then another

732
00:28:42,470 --> 00:28:41,039
one 12 days from now and in those images

733
00:28:44,710 --> 00:28:42,480
we'll be able to look

734
00:28:46,310 --> 00:28:44,720
for where the other components landed as

735
00:28:48,789 --> 00:28:46,320
a quick follow-up what's your best

736
00:28:50,310 --> 00:28:48,799
estimate for the resolution of what

737
00:28:52,470 --> 00:28:50,320
we're seeing here with the parachute how

738
00:28:54,870 --> 00:28:52,480
many centimeters per pixel 33

739
00:28:56,310 --> 00:28:54,880
centimeters per pixel thanks

740
00:28:58,230 --> 00:28:56,320
i'm going to keep handing it down the

741
00:28:59,350 --> 00:28:58,240
row i think there were a couple more by

742
00:29:00,549 --> 00:28:59,360
the way we just had one thing on that we

743
00:29:02,149 --> 00:29:00,559
know the the image we're trying to take

744
00:29:03,269 --> 00:29:02,159
as soon as as possible is to help with

745
00:29:05,029 --> 00:29:03,279
the problem that miguel was talking

746
00:29:06,710 --> 00:29:05,039
about which is which is to localize the

747
00:29:08,149 --> 00:29:06,720
the lander with respect to topographic

748
00:29:10,630 --> 00:29:08,159
features that we can see to get it

749
00:29:12,149 --> 00:29:10,640
registered onto a map to aid the uh the

750
00:29:13,590 --> 00:29:12,159
dynamic solution that miguel talked

751
00:29:16,310 --> 00:29:13,600
about so we hope to have that in just a

752
00:29:20,710 --> 00:29:18,870
uh leo enright with irish television uh

753
00:29:22,630 --> 00:29:20,720
the blogosphere got very excited very

754
00:29:24,470 --> 00:29:22,640
quickly after the hazcam pictures came

755
00:29:26,549 --> 00:29:24,480
down about a blotch

756
00:29:28,230 --> 00:29:26,559
that appeared in both of the images

757
00:29:30,950 --> 00:29:28,240
looking uh

758
00:29:33,350 --> 00:29:30,960
looking out across the plains which they

759
00:29:36,470 --> 00:29:33,360
were interpreting as possibly the

760
00:29:37,269 --> 00:29:36,480
landing stage uh impact uh certainly it

761
00:29:39,510 --> 00:29:37,279
was

762
00:29:40,870 --> 00:29:39,520
this this picture came down very quickly

763
00:29:43,590 --> 00:29:40,880
much quicker i think than many of us

764
00:29:45,830 --> 00:29:43,600
expected and so it seemed that it could

765
00:29:47,430 --> 00:29:45,840
be but i wondered did you any of you

766
00:29:50,230 --> 00:29:47,440
think that you saw

767
00:29:52,389 --> 00:29:50,240
evidence for the landing stage impact

768
00:29:54,149 --> 00:29:52,399
uh that artif that that artifact

769
00:29:55,510 --> 00:29:54,159
whatever it is in the image it has been

770
00:29:56,950 --> 00:29:55,520
seen has been it's been talked about

771
00:29:59,110 --> 00:29:56,960
it's been suggested it could be

772
00:30:01,190 --> 00:29:59,120
something associated with landing uh it

773
00:30:02,549 --> 00:30:01,200
could be a dust devil uh i think we

774
00:30:03,909 --> 00:30:02,559
don't know but we have noticed that

775
00:30:05,510 --> 00:30:03,919
feature and it's too early to tell what

776
00:30:07,029 --> 00:30:05,520
it is but but we would like to take a

777
00:30:08,630 --> 00:30:07,039
look at it again

778
00:30:09,909 --> 00:30:08,640
if it's a transient feature then you

779
00:30:11,350 --> 00:30:09,919
know we don't have another image of it

780
00:30:13,350 --> 00:30:11,360
we just have that one image right so we

781
00:30:14,630 --> 00:30:13,360
can't go back and look at it um of

782
00:30:15,909 --> 00:30:14,640
course if the descent stage is there

783
00:30:17,350 --> 00:30:15,919
that might tell us where you know where

784
00:30:18,549 --> 00:30:17,360
to look you know when we get all of our

785
00:30:19,590 --> 00:30:18,559
cameras up

786
00:30:21,029 --> 00:30:19,600
um

787
00:30:22,549 --> 00:30:21,039
maybe there's some hope that well a

788
00:30:23,830 --> 00:30:22,559
mardi image might have captured

789
00:30:25,269 --> 00:30:23,840
something as well the descent imager

790
00:30:26,789 --> 00:30:25,279
when we get that and we're just starting

791
00:30:28,070 --> 00:30:26,799
to trickle down thumbnails over the next

792
00:30:30,310 --> 00:30:28,080
few days of that it'll take a little

793
00:30:32,950 --> 00:30:30,320
while to to get that and miguel anything

794
00:30:33,909 --> 00:30:32,960
to add nope

795
00:30:35,110 --> 00:30:33,919
okay we're going to take one more

796
00:30:36,710 --> 00:30:35,120
question from that row and then todd

797
00:30:41,269 --> 00:30:36,720
we're coming over to your row next okay

798
00:30:44,870 --> 00:30:43,350
jonathan amos uh bbc news what's the the

799
00:30:46,630 --> 00:30:44,880
distance to the rim that we're seeing in

800
00:30:48,149 --> 00:30:46,640
the uh the image here you gave us a

801
00:30:50,389 --> 00:30:48,159
distance to the uh

802
00:30:52,389 --> 00:30:50,399
mount sharp what's what give us some

803
00:30:53,909 --> 00:30:52,399
sense of uh how far we are from the

804
00:30:55,669 --> 00:30:53,919
other large features the topographic

805
00:30:57,669 --> 00:30:55,679
features that you're talking about yeah

806
00:30:58,389 --> 00:30:57,679
let's just uh pull up the image again of

807
00:31:02,710 --> 00:30:58,399
the

808
00:31:04,149 --> 00:31:02,720
uh just uh

809
00:31:06,470 --> 00:31:04,159
in front of this one i believe that's

810
00:31:09,509 --> 00:31:06,480
showing there we go so the the ellipse

811
00:31:12,310 --> 00:31:09,519
there is 20 kilometers so if we land uh

812
00:31:14,789 --> 00:31:12,320
just to the right of the uh

813
00:31:15,669 --> 00:31:14,799
of the x in in the middle there

814
00:31:17,190 --> 00:31:15,679
you know

815
00:31:18,789 --> 00:31:17,200
i'd i'd guess on the order of 20

816
00:31:25,029 --> 00:31:18,799
kilometers to the rim something like

817
00:31:27,750 --> 00:31:26,549
okay we'll go we'll take one here in the

818
00:31:29,430 --> 00:31:27,760
front row and then we're going to move

819
00:31:31,990 --> 00:31:29,440
back here

820
00:31:34,070 --> 00:31:32,000
hi leonard david with aia aerospace

821
00:31:35,830 --> 00:31:34,080
america and space.com

822
00:31:38,470 --> 00:31:35,840
just curious on the

823
00:31:40,070 --> 00:31:38,480
sky crane as far as residual fuel i

824
00:31:41,909 --> 00:31:40,080
heard a number i just wonder if you got

825
00:31:44,389 --> 00:31:41,919
refinements on it and

826
00:31:47,350 --> 00:31:44,399
and what was the touchdown speed

827
00:31:51,029 --> 00:31:47,360
any way you can appreciate what exactly

828
00:31:54,230 --> 00:31:51,039
uh speed you hit uh surface well yes uh

829
00:31:56,230 --> 00:31:54,240
as far as the first i'm going to ask my

830
00:31:59,269 --> 00:31:56,240
friend and colleague adam he's not here

831
00:32:01,990 --> 00:31:59,279
because i don't but yeah it's 140 840

832
00:32:03,830 --> 00:32:02,000
kilograms i think it's 140 kilograms yes

833
00:32:05,909 --> 00:32:03,840
that's my memory yeah yes okay that

834
00:32:08,310 --> 00:32:05,919
sounds about right so we we ended up

835
00:32:11,110 --> 00:32:08,320
with a lot of kilograms of fuel

836
00:32:14,310 --> 00:32:11,120
which is a you know good thing i guess

837
00:32:19,269 --> 00:32:16,149
uh that you're saying as opposed to the

838
00:32:21,269 --> 00:32:19,279
opposite yes yes i take that first right

839
00:32:24,070 --> 00:32:21,279
at a touchdown speed oh the touch does

840
00:32:26,149 --> 00:32:24,080
be reported by this by this the

841
00:32:27,990 --> 00:32:26,159
spacecraft itself which navigation

842
00:32:30,149 --> 00:32:28,000
sensor is point seven it actually was

843
00:32:33,029 --> 00:32:30,159
dead on the money right you know prior

844
00:32:36,389 --> 00:32:33,039
to it the declaring touchdown okay so we

845
00:32:37,269 --> 00:32:36,399
were coming at 0.75 degrees now that's

846
00:32:38,149 --> 00:32:37,279
that's

847
00:32:42,389 --> 00:32:38,159
but

848
00:32:45,029 --> 00:32:42,399
excuse me 0.75 uh meters per second uh

849
00:32:45,750 --> 00:32:45,039
which is the intended velocity now

850
00:32:48,070 --> 00:32:45,760
uh

851
00:32:50,070 --> 00:32:48,080
if there is a bias or an error in the

852
00:32:51,590 --> 00:32:50,080
navigation sensor itself

853
00:32:53,350 --> 00:32:51,600
you could not tell

854
00:32:54,710 --> 00:32:53,360
that so it's going to require more

855
00:32:57,830 --> 00:32:54,720
analysis

856
00:32:59,350 --> 00:32:57,840
to really especially for marty it's

857
00:33:01,830 --> 00:32:59,360
going to be very useful

858
00:33:02,549 --> 00:33:01,840
uh to be able to really tease out what

859
00:33:07,430 --> 00:33:02,559
the

860
00:33:09,430 --> 00:33:07,440
right now we can only uh

861
00:33:11,669 --> 00:33:09,440
give you what the spacecraft thinks its

862
00:33:14,470 --> 00:33:11,679
velocity was and that was

863
00:33:17,190 --> 00:33:14,480
0.75 meters per second vertically and

864
00:33:19,110 --> 00:33:17,200
four centimeters per second horizontally

865
00:33:22,630 --> 00:33:19,120
okay so

866
00:33:25,110 --> 00:33:22,640
it's a very small number compared to

867
00:33:26,789 --> 00:33:25,120
two previous uh attempts so we'll see

868
00:33:28,549 --> 00:33:26,799
whether the uh

869
00:33:30,470 --> 00:33:28,559
the the the

870
00:33:32,149 --> 00:33:30,480
imaging coming down whether we can

871
00:33:34,389 --> 00:33:32,159
corroborate that number it would be nice

872
00:33:35,509 --> 00:33:34,399
for a guidance and control point of view

873
00:33:38,389 --> 00:33:35,519
if that's the case that's called

874
00:33:40,950 --> 00:33:38,399
straight down yes

875
00:33:43,430 --> 00:33:40,960
and maybe for sarah just maybe gauging

876
00:33:46,149 --> 00:33:43,440
the difficulty the degree of difficulty

877
00:33:49,269 --> 00:33:46,159
everybody's into the olympics

878
00:33:52,310 --> 00:33:49,279
you know between phoenix and imaging

879
00:33:53,669 --> 00:33:52,320
uh curiosity coming in what was the was

880
00:33:56,470 --> 00:33:53,679
it tougher was it

881
00:33:59,830 --> 00:33:56,480
it was tougher because of the the

882
00:34:02,389 --> 00:33:59,840
relative positions of the of the two

883
00:34:05,110 --> 00:34:02,399
spacecraft um

884
00:34:06,470 --> 00:34:05,120
i s the the team

885
00:34:08,869 --> 00:34:06,480
sort of internally

886
00:34:10,149 --> 00:34:08,879
guesstimated that phoenix wasn't they

887
00:34:12,550 --> 00:34:10,159
had an 80

888
00:34:15,349 --> 00:34:12,560
probability of getting that image and

889
00:34:17,909 --> 00:34:15,359
msl it was a 60 probability

890
00:34:18,829 --> 00:34:17,919
so this was you know this was a great

891
00:34:20,629 --> 00:34:18,839
great

892
00:34:23,270 --> 00:34:20,639
shot

893
00:34:25,510 --> 00:34:23,280
okay todd um todd halperson

894
00:34:28,230 --> 00:34:25,520
florida today and usa today for whoever

895
00:34:31,349 --> 00:34:28,240
can handle it um based on what you know

896
00:34:34,389 --> 00:34:31,359
right now could you update us on when

897
00:34:37,669 --> 00:34:34,399
you expect the delivery of

898
00:34:39,669 --> 00:34:37,679
higher resolution black and white photos

899
00:34:42,069 --> 00:34:39,679
color imagery

900
00:34:44,470 --> 00:34:42,079
the first panorama you mentioned

901
00:34:46,629 --> 00:34:44,480
thumbnails were coming down from marty

902
00:34:49,190 --> 00:34:46,639
and maybe the first

903
00:34:50,629 --> 00:34:49,200
full video from the descent camera

904
00:34:53,109 --> 00:34:50,639
thanks

905
00:34:54,710 --> 00:34:53,119
um yeah so basically the the the the

906
00:34:57,270 --> 00:34:54,720
date we're still in the nominal plan

907
00:34:59,030 --> 00:34:57,280
exactly um and i think uh in one of the

908
00:35:01,430 --> 00:34:59,040
earlier press conferences uh richard

909
00:35:02,470 --> 00:35:01,440
cook uh gave a a approximate list of

910
00:35:04,550 --> 00:35:02,480
dates

911
00:35:06,150 --> 00:35:04,560
um so basically we we start to get we

912
00:35:07,990 --> 00:35:06,160
believe we'll get

913
00:35:09,670 --> 00:35:08,000
a front haz cam

914
00:35:11,670 --> 00:35:09,680
that has the same resolution as the rear

915
00:35:14,870 --> 00:35:11,680
that we were showing today uh in just a

916
00:35:16,390 --> 00:35:14,880
couple of hours from now about 11 30

917
00:35:19,030 --> 00:35:16,400
and we will start to trickle down some

918
00:35:20,870 --> 00:35:19,040
thumbnails from the descent imager and

919
00:35:23,430 --> 00:35:20,880
then in the next day or two after that

920
00:35:25,829 --> 00:35:23,440
we start getting um uh better resolution

921
00:35:27,270 --> 00:35:25,839
marty's as well as our first panoramas

922
00:35:30,310 --> 00:35:27,280
of the from these are black and white

923
00:35:32,150 --> 00:35:30,320
panoramas we also get a single color

924
00:35:33,670 --> 00:35:32,160
frame from the mali instrument which is

925
00:35:35,750 --> 00:35:33,680
in the stowed position but it looks out

926
00:35:37,510 --> 00:35:35,760
to the side and it can focus at infinity

927
00:35:40,069 --> 00:35:37,520
and that will look a lot like a single

928
00:35:41,270 --> 00:35:40,079
frame you know kind of panoramic um

929
00:35:42,870 --> 00:35:41,280
image that you're used to seeing you

930
00:35:44,390 --> 00:35:42,880
know it looks like it doesn't look like

931
00:35:46,790 --> 00:35:44,400
it it's taken from a microscope it looks

932
00:35:48,630 --> 00:35:46,800
like you know a a regular camera since

933
00:35:49,990 --> 00:35:48,640
it focuses at infinity so that will be

934
00:35:51,990 --> 00:35:50,000
the first color image that we get down

935
00:35:55,030 --> 00:35:52,000
that molle image and it's uh about two

936
00:35:59,270 --> 00:35:56,550
okay uh you were next and then we're

937
00:36:01,270 --> 00:35:59,280
going to come forward to you and then

938
00:36:03,030 --> 00:36:01,280
oh hi this

939
00:36:04,150 --> 00:36:03,040
is mike wall from space.com i guess this

940
00:36:06,069 --> 00:36:04,160
is from

941
00:36:07,670 --> 00:36:06,079
or this is for john if you guys can't

942
00:36:09,750 --> 00:36:07,680
actually find where the sky crane came

943
00:36:11,270 --> 00:36:09,760
down or or actually identify some of the

944
00:36:12,870 --> 00:36:11,280
craters that were created by the ballast

945
00:36:13,990 --> 00:36:12,880
being injected i mean

946
00:36:15,510 --> 00:36:14,000
like

947
00:36:17,829 --> 00:36:15,520
yeah how high of priority would it be to

948
00:36:19,910 --> 00:36:17,839
go check out those new fresh impact

949
00:36:21,349 --> 00:36:19,920
craters as as sort of compared to all

950
00:36:24,069 --> 00:36:21,359
the other work that that you would like

951
00:36:28,950 --> 00:36:27,349
an inevitable question uh i you know i

952
00:36:30,710 --> 00:36:28,960
in terms of where the sky crane came

953
00:36:33,510 --> 00:36:30,720
down the descent stage with all the

954
00:36:35,430 --> 00:36:33,520
hydrazine that that uh might be present

955
00:36:37,109 --> 00:36:35,440
there we would we would actually really

956
00:36:40,470 --> 00:36:37,119
prefer to avoid that

957
00:36:42,870 --> 00:36:40,480
and i i don't doubt that if if our

958
00:36:44,790 --> 00:36:42,880
path of science takes us near it we're

959
00:36:46,950 --> 00:36:44,800
we're really going to try to image it

960
00:36:49,030 --> 00:36:46,960
and do everything we can to study it but

961
00:36:50,950 --> 00:36:49,040
otherwise we try to avoid it as far as

962
00:36:53,349 --> 00:36:50,960
the balance goes that was something that

963
00:36:55,510 --> 00:36:53,359
that i was really hoping for

964
00:36:57,510 --> 00:36:55,520
and then i talked to miguel and adam i

965
00:37:00,390 --> 00:36:57,520
those blocks are ejected so far down

966
00:37:01,829 --> 00:37:00,400
track we have no hope but you know

967
00:37:03,430 --> 00:37:01,839
striking the surface they might give us

968
00:37:05,589 --> 00:37:03,440
a nice fresh exposure without any

969
00:37:07,190 --> 00:37:05,599
contamination so but that doesn't seem

970
00:37:08,950 --> 00:37:07,200
like it's in the cards

971
00:37:09,750 --> 00:37:08,960
i'd like to add a little thing to that

972
00:37:10,950 --> 00:37:09,760
um

973
00:37:14,790 --> 00:37:10,960
we actually

974
00:37:17,910 --> 00:37:14,800
on purpose we instructed the cent stage

975
00:37:20,230 --> 00:37:17,920
to uh fly away from where the science is

976
00:37:22,150 --> 00:37:20,240
not to contaminate it so we actually if

977
00:37:22,950 --> 00:37:22,160
you you know we gave a command to this

978
00:37:26,550 --> 00:37:22,960
to

979
00:37:27,750 --> 00:37:26,560
draw a line from

980
00:37:29,829 --> 00:37:27,760
east west

981
00:37:32,470 --> 00:37:29,839
to go north of that line

982
00:37:34,310 --> 00:37:32,480
exactly in what direction depends on the

983
00:37:36,870 --> 00:37:34,320
orientation of the of the descent stage

984
00:37:39,270 --> 00:37:36,880
at that point because we want to do a

985
00:37:40,470 --> 00:37:39,280
turn with the thrusters away from the

986
00:37:41,270 --> 00:37:40,480
spacecraft

987
00:37:43,589 --> 00:37:41,280
so

988
00:37:45,910 --> 00:37:43,599
we have done everything possible to fly

989
00:37:47,670 --> 00:37:45,920
it away from where the science is so we

990
00:37:48,829 --> 00:37:47,680
would make

991
00:37:51,910 --> 00:37:48,839
that

992
00:37:55,829 --> 00:37:51,920
even more difficult

993
00:37:59,109 --> 00:37:58,069
irene klotz with reuters and discovery

994
00:38:01,349 --> 00:37:59,119
news

995
00:38:03,910 --> 00:38:01,359
two quick housekeeping questions is the

996
00:38:06,470 --> 00:38:03,920
first is how many pictures not including

997
00:38:09,829 --> 00:38:06,480
the stunning mro shot has

998
00:38:11,750 --> 00:38:09,839
msl returned so far and what time is the

999
00:38:13,510 --> 00:38:11,760
high gain supposed to be

1000
00:38:15,670 --> 00:38:13,520
deployed and then i have a question for

1001
00:38:16,829 --> 00:38:15,680
john

1002
00:38:18,470 --> 00:38:16,839
it has

1003
00:38:21,829 --> 00:38:18,480
returned

1004
00:38:24,470 --> 00:38:21,839
uh four thumbnails

1005
00:38:28,630 --> 00:38:24,480
two down sampled images with the covers

1006
00:38:31,430 --> 00:38:28,640
on and one those are 256x256 and one 512

1007
00:38:33,190 --> 00:38:31,440
by 512 down sampled rear haz cam with

1008
00:38:35,589 --> 00:38:33,200
the cover off

1009
00:38:37,270 --> 00:38:35,599
i think that's everything

1010
00:38:41,270 --> 00:38:37,280
and the high gain deploy high gain

1011
00:38:42,710 --> 00:38:41,280
deploy is in the afternoon mars time

1012
00:38:44,870 --> 00:38:42,720
uh today

1013
00:38:47,430 --> 00:38:44,880
so about

1014
00:38:49,990 --> 00:38:47,440
12 hours from now or so

1015
00:38:51,829 --> 00:38:50,000
thanks and um for john you mentioned

1016
00:38:53,910 --> 00:38:51,839
that uh one of the first things you

1017
00:38:56,550 --> 00:38:53,920
might like to do is uh do a

1018
00:38:57,510 --> 00:38:56,560
representative soil analysis i was just

1019
00:38:59,910 --> 00:38:57,520
curious

1020
00:39:01,190 --> 00:38:59,920
what sort of variations in the soil is

1021
00:39:04,390 --> 00:39:01,200
there from

1022
00:39:06,790 --> 00:39:04,400
viking one to spirit opportunity and

1023
00:39:08,870 --> 00:39:06,800
phoenix if that's a valid sample just

1024
00:39:10,069 --> 00:39:08,880
what sort of variation have you seen in

1025
00:39:11,829 --> 00:39:10,079
the past and

1026
00:39:14,870 --> 00:39:11,839
what might you be looking for that's

1027
00:39:16,630 --> 00:39:14,880
different on this site thanks

1028
00:39:18,630 --> 00:39:16,640
yeah it's uh there's there's two

1029
00:39:21,270 --> 00:39:18,640
separate objectives you know the one

1030
00:39:24,230 --> 00:39:21,280
that we're also after is the composition

1031
00:39:26,310 --> 00:39:24,240
of the bedrock but we we infer that the

1032
00:39:28,550 --> 00:39:26,320
composition of the bedrock is going to

1033
00:39:30,790 --> 00:39:28,560
represent local processes that happen

1034
00:39:33,910 --> 00:39:30,800
that form that bedrock

1035
00:39:36,230 --> 00:39:33,920
whereas the the soil of mars in a place

1036
00:39:39,190 --> 00:39:36,240
like we've landed in will represent a

1037
00:39:41,510 --> 00:39:39,200
more global integrated average of of

1038
00:39:43,190 --> 00:39:41,520
dust that has blown around the planet

1039
00:39:45,510 --> 00:39:43,200
and other materials that have worked

1040
00:39:48,470 --> 00:39:45,520
their way over long distances

1041
00:39:49,910 --> 00:39:48,480
and and while we have no independent way

1042
00:39:52,550 --> 00:39:49,920
to demonstrate that what we might

1043
00:39:55,030 --> 00:39:52,560
measure with curiosity

1044
00:39:57,990 --> 00:39:55,040
must be analogous to what was measured

1045
00:39:59,990 --> 00:39:58,000
with viking many decades ago

1046
00:40:01,910 --> 00:40:00,000
the character of the soil every time

1047
00:40:04,630 --> 00:40:01,920
we've sampled it beginning with viking

1048
00:40:06,470 --> 00:40:04,640
and most recently with the mers

1049
00:40:07,510 --> 00:40:06,480
for example has a very high sulfur

1050
00:40:09,349 --> 00:40:07,520
content

1051
00:40:11,990 --> 00:40:09,359
we'd like to know definitively what

1052
00:40:14,470 --> 00:40:12,000
minerals are in that soil and so by

1053
00:40:15,990 --> 00:40:14,480
analyzing it with sam and chemin for

1054
00:40:18,550 --> 00:40:16,000
example

1055
00:40:20,710 --> 00:40:18,560
we can get a better understanding of of

1056
00:40:22,470 --> 00:40:20,720
what the composition of the soil is

1057
00:40:24,790 --> 00:40:22,480
certainly where we've landed and by

1058
00:40:27,829 --> 00:40:24,800
inference maybe also globally

1059
00:40:29,430 --> 00:40:27,839
and uh and and through that get it one

1060
00:40:31,109 --> 00:40:29,440
of the most global questions we could

1061
00:40:32,790 --> 00:40:31,119
address

1062
00:40:34,550 --> 00:40:32,800
okay we're going first to bill harwood

1063
00:40:36,470 --> 00:40:34,560
and then alan thank you thanks bill

1064
00:40:37,750 --> 00:40:36,480
hartwick cbs news i'm just continuing on

1065
00:40:39,670 --> 00:40:37,760
soil for a bit john just from a

1066
00:40:41,270 --> 00:40:39,680
mechanical standpoint were you guys

1067
00:40:43,670 --> 00:40:41,280
surprised at the amount of dust on the

1068
00:40:45,750 --> 00:40:43,680
dust cover given how high the engines

1069
00:40:47,430 --> 00:40:45,760
were seven and a half meters or whatever

1070
00:40:48,790 --> 00:40:47,440
at the top of that bridle does that tell

1071
00:40:50,230 --> 00:40:48,800
you anything about

1072
00:40:51,829 --> 00:40:50,240
the consistency or the mechanical

1073
00:40:54,390 --> 00:40:51,839
properties of the soil it's a good

1074
00:40:57,670 --> 00:40:54,400
question uh i i think we were surprised

1075
00:41:00,550 --> 00:40:57,680
because the images that uh have the dust

1076
00:41:03,270 --> 00:41:00,560
covers off still show some dust on them

1077
00:41:05,910 --> 00:41:03,280
so so some little bit got in there on

1078
00:41:07,990 --> 00:41:05,920
the other hand based on myrrh experience

1079
00:41:09,990 --> 00:41:08,000
the dust comes and goes and when the

1080
00:41:11,910 --> 00:41:10,000
wind blows and it's a clear air flow it

1081
00:41:13,349 --> 00:41:11,920
will probably just blow it right off and

1082
00:41:15,990 --> 00:41:13,359
then it will come back on again when we

1083
00:41:18,710 --> 00:41:16,000
have a dust storm or a dust devil go by

1084
00:41:20,950 --> 00:41:18,720
and it'll sort of wax and wane

1085
00:41:23,349 --> 00:41:20,960
um

1086
00:41:25,349 --> 00:41:23,359
the the other interesting observation is

1087
00:41:28,309 --> 00:41:25,359
if you look at that rear haz cam image

1088
00:41:31,430 --> 00:41:28,319
again you'll notice that the the wheel

1089
00:41:34,470 --> 00:41:31,440
is on relatively firm ground and so with

1090
00:41:37,750 --> 00:41:34,480
miguel's estimate of 0.75 meters per

1091
00:41:40,230 --> 00:41:37,760
second descent velocity straight down we

1092
00:41:42,470 --> 00:41:40,240
didn't get any sinkage there so you know

1093
00:41:44,630 --> 00:41:42,480
that's a that's sort of a inference

1094
00:41:46,309 --> 00:41:44,640
inferential science observation that the

1095
00:41:49,030 --> 00:41:46,319
material we landed on has pretty

1096
00:41:50,550 --> 00:41:49,040
substantial bearing strength and is is

1097
00:41:53,349 --> 00:41:50,560
probably firm

1098
00:41:54,710 --> 00:41:53,359
and uh so for that reason we might

1099
00:41:56,710 --> 00:41:54,720
choose to drive somewhere else to

1100
00:41:58,230 --> 00:41:56,720
actually get our scoop out and and dig

1101
00:41:59,750 --> 00:41:58,240
in there because the first thing that we

1102
00:42:00,829 --> 00:41:59,760
want to scoop we really do want to be a

1103
00:42:03,430 --> 00:42:00,839
pretty soft

1104
00:42:05,190 --> 00:42:03,440
material thanks and and for mike you

1105
00:42:06,790 --> 00:42:05,200
mentioned the the health of the vehicle

1106
00:42:08,230 --> 00:42:06,800
as you know it today and realizing it's

1107
00:42:09,670 --> 00:42:08,240
not all in yet but

1108
00:42:11,190 --> 00:42:09,680
uh are there any glitches or any

1109
00:42:13,270 --> 00:42:11,200
anomalies at all on the day even if

1110
00:42:14,870 --> 00:42:13,280
they're minor and for all of you really

1111
00:42:16,630 --> 00:42:14,880
or for any of you i mean you guys have

1112
00:42:17,990 --> 00:42:16,640
convinced us you know really

1113
00:42:19,750 --> 00:42:18,000
how how

1114
00:42:21,190 --> 00:42:19,760
technically difficult this was i think a

1115
00:42:23,349 --> 00:42:21,200
lot of folks had a lot of trepidation

1116
00:42:25,430 --> 00:42:23,359
going into this folks on the outside did

1117
00:42:27,510 --> 00:42:25,440
you guys ever imagine you'd be here this

1118
00:42:32,150 --> 00:42:27,520
morning with the vehicle and the shape

1119
00:42:34,390 --> 00:42:32,160
it's in uh telling us this story thanks

1120
00:42:36,069 --> 00:42:34,400
um there is there are no known there are

1121
00:42:38,230 --> 00:42:36,079
no anomalies that are outside the

1122
00:42:39,670 --> 00:42:38,240
expected range that that we would think

1123
00:42:40,790 --> 00:42:39,680
is okay to proceed with activities you

1124
00:42:42,829 --> 00:42:40,800
know some things are doing a little

1125
00:42:44,870 --> 00:42:42,839
better some systems are you

1126
00:42:46,150 --> 00:42:44,880
know reading a little higher than we

1127
00:42:47,430 --> 00:42:46,160
expected some a little lower but

1128
00:42:49,030 --> 00:42:47,440
everything sort of within the accepted

1129
00:42:50,950 --> 00:42:49,040
bounds that we view as being acceptable

1130
00:42:52,470 --> 00:42:50,960
to you know to move forward there's no

1131
00:42:54,390 --> 00:42:52,480
no real anomaly in work that's causing

1132
00:42:56,470 --> 00:42:54,400
us to slow down and defer activities

1133
00:42:57,589 --> 00:42:56,480
because of that um but you know because

1134
00:42:59,589 --> 00:42:57,599
we're engineers and because we're

1135
00:43:01,270 --> 00:42:59,599
perfectionists every little thing that's

1136
00:43:02,870 --> 00:43:01,280
different has you know folks want to go

1137
00:43:04,630 --> 00:43:02,880
take a look at you know why is this five

1138
00:43:06,150 --> 00:43:04,640
percent different from the way it was in

1139
00:43:08,069 --> 00:43:06,160
the test you know

1140
00:43:09,910 --> 00:43:08,079
um and that will continue but but you

1141
00:43:12,230 --> 00:43:09,920
know we're still moving forward

1142
00:43:13,349 --> 00:43:12,240
um you know i in terms of success i

1143
00:43:15,589 --> 00:43:13,359
think each of us would answer that

1144
00:43:17,430 --> 00:43:15,599
differently uh i think we all believed

1145
00:43:18,950 --> 00:43:17,440
it would land successfully although we

1146
00:43:20,069 --> 00:43:18,960
were worried because we wouldn't be

1147
00:43:22,150 --> 00:43:20,079
working on it and we wouldn't have

1148
00:43:24,230 --> 00:43:22,160
designed a two-year surface mission with

1149
00:43:25,750 --> 00:43:24,240
all of the science payload and a 20

1150
00:43:28,390 --> 00:43:25,760
kilometer traverse if we thought it was

1151
00:43:30,230 --> 00:43:28,400
not going to land successfully um i

1152
00:43:32,069 --> 00:43:30,240
think um as pete is mentioned several

1153
00:43:33,910 --> 00:43:32,079
times um

1154
00:43:35,510 --> 00:43:33,920
we're always it's a very complex vehicle

1155
00:43:36,630 --> 00:43:35,520
and we're we're a little bit concerned

1156
00:43:41,349 --> 00:43:36,640
that

1157
00:43:44,470 --> 00:43:41,359
would take us a little while to get out

1158
00:43:46,390 --> 00:43:44,480
of it uh we might not get a a calm pass

1159
00:43:47,510 --> 00:43:46,400
and you know um just for telecom reasons

1160
00:43:48,550 --> 00:43:47,520
the rover might have been perfectly

1161
00:43:50,390 --> 00:43:48,560
healthy but you didn't get the

1162
00:43:52,790 --> 00:43:50,400
communications pass with the orbiter and

1163
00:43:54,470 --> 00:43:52,800
so you have to sit in and and worry and

1164
00:43:55,829 --> 00:43:54,480
and and just wait

1165
00:43:57,589 --> 00:43:55,839
um the fact that it that it went

1166
00:44:00,150 --> 00:43:57,599
straight into surface nominal didn't

1167
00:44:02,069 --> 00:44:00,160
safe uh we got great telecom performance

1168
00:44:03,270 --> 00:44:02,079
the orbiters performed beautifully um

1169
00:44:05,190 --> 00:44:03,280
that you know this very complicated

1170
00:44:06,390 --> 00:44:05,200
avionics with reno redundant computers

1171
00:44:08,710 --> 00:44:06,400
and redundant

1172
00:44:10,069 --> 00:44:08,720
um avionics modules has all been fine

1173
00:44:11,829 --> 00:44:10,079
and and i think we're pleasantly

1174
00:44:12,870 --> 00:44:11,839
surprised at how smooth that part is is

1175
00:44:14,150 --> 00:44:12,880
going

1176
00:44:15,510 --> 00:44:14,160
and miguel do you want to comment on

1177
00:44:17,510 --> 00:44:15,520
there yeah

1178
00:44:19,190 --> 00:44:17,520
yeah that's that's you explain it very

1179
00:44:22,230 --> 00:44:19,200
well i mean if we if we didn't feel that

1180
00:44:23,750 --> 00:44:22,240
it it was doable or we felt there was no

1181
00:44:25,030 --> 00:44:23,760
no chance of success we would not be

1182
00:44:27,190 --> 00:44:25,040
doing it

1183
00:44:29,270 --> 00:44:27,200
that said i mean we train ourselves for

1184
00:44:31,589 --> 00:44:29,280
eight years to think the worst all the

1185
00:44:33,750 --> 00:44:31,599
time what how come we you know if you're

1186
00:44:36,710 --> 00:44:33,760
in the shower thinking what what what

1187
00:44:38,390 --> 00:44:36,720
thing come you can give you a bad day i

1188
00:44:39,750 --> 00:44:38,400
mean that's what you do i mean it's

1189
00:44:41,510 --> 00:44:39,760
constantly

1190
00:44:43,910 --> 00:44:41,520
thinking ways that things can go wrong

1191
00:44:45,750 --> 00:44:43,920
so you can go and do something about it

1192
00:44:48,309 --> 00:44:45,760
and then you can never turn that off

1193
00:44:49,109 --> 00:44:48,319
okay and then it's all the way in you

1194
00:44:52,390 --> 00:44:49,119
are

1195
00:44:54,790 --> 00:44:52,400
you know and especially the few days

1196
00:44:56,870 --> 00:44:54,800
into the uh

1197
00:44:58,630 --> 00:44:56,880
the few days coming to the landing when

1198
00:45:00,870 --> 00:44:58,640
you also know that you don't have time

1199
00:45:02,790 --> 00:45:00,880
to recover it's even more

1200
00:45:04,309 --> 00:45:02,800
uh the the

1201
00:45:07,030 --> 00:45:04,319
the

1202
00:45:09,109 --> 00:45:07,040
pressure is even higher uh so

1203
00:45:11,510 --> 00:45:09,119
um it is a you know a landing is a

1204
00:45:13,829 --> 00:45:11,520
little bit like a rocket launch okay

1205
00:45:15,109 --> 00:45:13,839
it's that type of violence that's so

1206
00:45:17,430 --> 00:45:15,119
unforgiving

1207
00:45:20,069 --> 00:45:17,440
okay and even till these days once in a

1208
00:45:22,309 --> 00:45:20,079
while we lose a launch and uh and we

1209
00:45:24,309 --> 00:45:22,319
were very nervous on this launch and

1210
00:45:25,750 --> 00:45:24,319
those are things that we practice

1211
00:45:27,109 --> 00:45:25,760
much more

1212
00:45:28,150 --> 00:45:27,119
you know you can actually count the

1213
00:45:30,550 --> 00:45:28,160
numbers of

1214
00:45:33,109 --> 00:45:30,560
mars landing with one hand and

1215
00:45:35,990 --> 00:45:33,119
it's so it's it's so it's going to take

1216
00:45:37,829 --> 00:45:36,000
a long long time for us to really

1217
00:45:39,510 --> 00:45:37,839
be totally sure that these things are

1218
00:45:42,309 --> 00:45:39,520
going to work like you feel sure about

1219
00:45:43,270 --> 00:45:42,319
an airplane taking off and landing so

1220
00:45:45,270 --> 00:45:43,280
um

1221
00:45:46,630 --> 00:45:45,280
but that's what we're going to need but

1222
00:45:47,829 --> 00:45:46,640
you know we're going to continue trying

1223
00:45:49,829 --> 00:45:47,839
and we're going to be nervous the next

1224
00:45:51,990 --> 00:45:49,839
time the same no matter how well this

1225
00:45:53,829 --> 00:45:52,000
one worked

1226
00:45:57,750 --> 00:45:53,839
i think we need two hands now though

1227
00:45:57,760 --> 00:46:03,670
just barely just barely

1228
00:46:07,510 --> 00:46:05,750
nbc news and

1229
00:46:10,230 --> 00:46:07,520
just a couple of questions that i

1230
00:46:12,309 --> 00:46:10,240
may have missed um

1231
00:46:16,230 --> 00:46:12,319
is there any marty imagery from the

1232
00:46:18,950 --> 00:46:16,240
descendant imager uh and on the mro

1233
00:46:21,109 --> 00:46:18,960
picture uh what's the distance from

1234
00:46:23,109 --> 00:46:21,119
which that picture was taken where where

1235
00:46:26,230 --> 00:46:23,119
is the

1236
00:46:29,190 --> 00:46:26,240
the rover in relation to mro

1237
00:46:31,030 --> 00:46:29,200
there is no marty data down right now um

1238
00:46:33,349 --> 00:46:31,040
in uh about an hour and a half from now

1239
00:46:36,150 --> 00:46:33,359
or so two hours uh we're going to get

1240
00:46:37,990 --> 00:46:36,160
another pass from the orbiters and uh we

1241
00:46:39,109 --> 00:46:38,000
we might get some marty thumbnails in

1242
00:46:40,309 --> 00:46:39,119
that you know these are very small to

1243
00:46:42,470 --> 00:46:40,319
help us understand what are the right

1244
00:46:45,349 --> 00:46:42,480
images to you know to grab from marty

1245
00:46:49,349 --> 00:46:45,359
but as of today they're not down

1246
00:46:51,829 --> 00:46:49,359
and mro was 340 kilometers

1247
00:46:53,750 --> 00:46:51,839
from msl

1248
00:46:55,589 --> 00:46:53,760
and i'll just point out that we do hope

1249
00:46:57,349 --> 00:46:55,599
to hold another news conference at four

1250
00:46:59,030 --> 00:46:57,359
o'clock today pacific time to show the

1251
00:47:00,630 --> 00:46:59,040
marty thumbnails if we do indeed get

1252
00:47:02,550 --> 00:47:00,640
those today so we'll have an update for

1253
00:47:03,829 --> 00:47:02,560
you that soon soon all right let's go

1254
00:47:05,829 --> 00:47:03,839
back to by the way i want to correct one

1255
00:47:07,349 --> 00:47:05,839
thing i said about the time of the hda

1256
00:47:08,710 --> 00:47:07,359
deploy i think i said it ends in the

1257
00:47:12,470 --> 00:47:08,720
afternoon about one o'clock it starts

1258
00:47:13,910 --> 00:47:12,480
about 11 o'clock mars time

1259
00:47:14,950 --> 00:47:13,920
and it ends in the afternoon starts just

1260
00:47:16,630 --> 00:47:14,960
before noon

1261
00:47:17,829 --> 00:47:16,640
okay let's go uh first to emily lock

1262
00:47:19,750 --> 00:47:17,839
dewalla and then we'll go back to john

1263
00:47:20,549 --> 00:47:19,760
johnson she's got her hand up there we

1264
00:47:22,390 --> 00:47:20,559
go

1265
00:47:23,670 --> 00:47:22,400
i have two questions the first one is do

1266
00:47:27,430 --> 00:47:23,680
we have any information yet on the

1267
00:47:29,990 --> 00:47:27,440
health of any of the science instruments

1268
00:47:31,190 --> 00:47:30,000
um yes we have we have we have a health

1269
00:47:32,710 --> 00:47:31,200
of many of them all of them that we've

1270
00:47:34,150 --> 00:47:32,720
done to check out and they're all fine

1271
00:47:36,150 --> 00:47:34,160
they're all in in perfect health and

1272
00:47:37,910 --> 00:47:36,160
operating as expected

1273
00:47:39,990 --> 00:47:37,920
um and the second one is that it's a

1274
00:47:42,150 --> 00:47:40,000
well-known adage that if you get 406

1275
00:47:43,829 --> 00:47:42,160
scientists in a room there will be 407

1276
00:47:45,750 --> 00:47:43,839
different opinions about what's going on

1277
00:47:47,910 --> 00:47:45,760
so i was wondering it's i know it's very

1278
00:47:49,430 --> 00:47:47,920
early but if you have any kind of

1279
00:47:50,549 --> 00:47:49,440
different ideas that are floating around

1280
00:47:53,190 --> 00:47:50,559
about some of the things you're seeing

1281
00:47:56,470 --> 00:47:53,200
in the foreground there

1282
00:47:59,510 --> 00:47:56,480
um it it is uh i i think it is uh still

1283
00:48:00,790 --> 00:47:59,520
early and as you might guess um

1284
00:48:02,790 --> 00:48:00,800
there's only a limited amount of

1285
00:48:06,470 --> 00:48:02,800
information that we can we can draw from

1286
00:48:07,510 --> 00:48:06,480
this and uh and i i think that uh

1287
00:48:09,910 --> 00:48:07,520
uh

1288
00:48:12,470 --> 00:48:09,920
the the team we had a great discussion

1289
00:48:13,430 --> 00:48:12,480
this morning and uh i i think most

1290
00:48:15,990 --> 00:48:13,440
people

1291
00:48:18,710 --> 00:48:16,000
uh felt that we're on a gravel plane of

1292
00:48:20,710 --> 00:48:18,720
mars a somewhat familiar scene but with

1293
00:48:22,470 --> 00:48:20,720
a rather uniform grain size distribution

1294
00:48:24,710 --> 00:48:22,480
this does not look like a ballistic

1295
00:48:27,589 --> 00:48:24,720
impact ejecta for example

1296
00:48:29,349 --> 00:48:27,599
and um is that the rim in the background

1297
00:48:31,510 --> 00:48:29,359
everybody agrees on that

1298
00:48:34,309 --> 00:48:31,520
uh we had a lot of discussion about the

1299
00:48:36,790 --> 00:48:34,319
alluvial fan how we might explore the

1300
00:48:38,630 --> 00:48:36,800
the ellipse and uh

1301
00:48:41,349 --> 00:48:38,640
and discussion about that

1302
00:48:44,549 --> 00:48:41,359
uh i'm i'm kind of amazed with uh we did

1303
00:48:47,190 --> 00:48:44,559
this uh crowdsourcing exercise and

1304
00:48:50,230 --> 00:48:47,200
mapping and uh a bunch of people got

1305
00:48:51,430 --> 00:48:50,240
quads and and we had a remarkable amount

1306
00:48:53,990 --> 00:48:51,440
of agreement

1307
00:48:55,990 --> 00:48:54,000
uh which is probably mostly a testimony

1308
00:48:57,349 --> 00:48:56,000
to to the relative simplicity of the

1309
00:48:58,549 --> 00:48:57,359
geology

1310
00:49:00,230 --> 00:48:58,559
and uh

1311
00:49:02,069 --> 00:49:00,240
and that's a good thing because we're a

1312
00:49:03,510 --> 00:49:02,079
complex spacecraft and and simple

1313
00:49:06,069 --> 00:49:03,520
geology is a good thing to start off

1314
00:49:09,750 --> 00:49:08,069
okay um i know we've had uh you've been

1315
00:49:11,190 --> 00:49:09,760
waiting for oh i'm sorry john johnson is

1316
00:49:12,870 --> 00:49:11,200
next but after that we're going to you

1317
00:49:14,069 --> 00:49:12,880
and then we will go back down that row

1318
00:49:16,309 --> 00:49:14,079
over there and then come back here

1319
00:49:18,390 --> 00:49:16,319
thanks go ahead john thank you i just

1320
00:49:19,510 --> 00:49:18,400
wanted to follow up on the last question

1321
00:49:20,870 --> 00:49:19,520
about the health of the science

1322
00:49:22,710 --> 00:49:20,880
instruments um

1323
00:49:25,030 --> 00:49:22,720
it seems to me the sam instrument with

1324
00:49:26,309 --> 00:49:25,040
all those moving parts is particularly

1325
00:49:28,870 --> 00:49:26,319
well i don't know if delicate's the

1326
00:49:30,710 --> 00:49:28,880
right word but in you say the

1327
00:49:32,870 --> 00:49:30,720
instruments have so far checked out i

1328
00:49:35,270 --> 00:49:32,880
mean can you say anything specifically

1329
00:49:39,349 --> 00:49:35,280
about sam and and whether you feel

1330
00:49:42,309 --> 00:49:40,230
um

1331
00:49:44,390 --> 00:49:42,319
john you want to comment on that yeah

1332
00:49:46,630 --> 00:49:44,400
there's a there's a series of tests uh

1333
00:49:49,670 --> 00:49:46,640
that related to relate to sam's uh

1334
00:49:51,510 --> 00:49:49,680
performance and uh and so today it was a

1335
00:49:53,190 --> 00:49:51,520
electrical test that that worked well

1336
00:49:54,549 --> 00:49:53,200
the first first test and everything

1337
00:49:56,069 --> 00:49:54,559
looked nominal with

1338
00:49:58,150 --> 00:49:56,079
with regard to that

1339
00:49:59,589 --> 00:49:58,160
okay and what happened to that dust

1340
00:50:01,670 --> 00:49:59,599
storm that was talked about a couple

1341
00:50:03,910 --> 00:50:01,680
days ago dissipated

1342
00:50:05,109 --> 00:50:03,920
beautiful clear day okay when we landed

1343
00:50:06,230 --> 00:50:05,119
yeah

1344
00:50:07,829 --> 00:50:06,240
and certainly you're right you know we

1345
00:50:09,109 --> 00:50:07,839
we have not completely checked out all

1346
00:50:10,790 --> 00:50:09,119
the modes of these instruments we first

1347
00:50:13,109 --> 00:50:10,800
do kind of just uh you know electrical

1348
00:50:14,150 --> 00:50:13,119
tests and and basic basic tests of of

1349
00:50:15,829 --> 00:50:14,160
the instruments and there's a lot of

1350
00:50:17,430 --> 00:50:15,839
scientific calibration and a lot of

1351
00:50:19,190 --> 00:50:17,440
extra modes and complex modes of the

1352
00:50:20,790 --> 00:50:19,200
instruments that will take us a long

1353
00:50:21,990 --> 00:50:20,800
time to get through and that's true of

1354
00:50:23,589 --> 00:50:22,000
our own systems you know the drilling

1355
00:50:24,390 --> 00:50:23,599
system the saw spa and all of that so

1356
00:50:25,510 --> 00:50:24,400
you know

1357
00:50:26,710 --> 00:50:25,520
we should not think that we're that

1358
00:50:29,030 --> 00:50:26,720
we're completely out of the water yet

1359
00:50:30,630 --> 00:50:29,040
we've we've got weeks if not months of

1360
00:50:32,470 --> 00:50:30,640
of checkout before we're completely

1361
00:50:35,190 --> 00:50:32,480
confident in the entire payload yeah

1362
00:50:36,710 --> 00:50:35,200
just a little bit more the one major

1363
00:50:39,190 --> 00:50:36,720
observation that we planned today is a

1364
00:50:41,270 --> 00:50:39,200
rad observation for five hours

1365
00:50:43,829 --> 00:50:41,280
and there was plenty of time to do that

1366
00:50:47,510 --> 00:50:43,839
so that's not a check out that's the 100

1367
00:50:52,309 --> 00:50:49,670
hi i'm raphael garcia with volley sao

1368
00:50:55,829 --> 00:50:52,319
paulo brazil my question is for sarah

1369
00:50:57,750 --> 00:50:55,839
is will mro be able to spot the rover in

1370
00:50:59,190 --> 00:50:57,760
the ground even if it's just a single

1371
00:50:59,990 --> 00:50:59,200
pixel and

1372
00:51:02,710 --> 00:51:00,000
uh

1373
00:51:04,790 --> 00:51:02,720
will the arbiter have any role in

1374
00:51:07,190 --> 00:51:04,800
helping the rover navigator part from

1375
00:51:08,630 --> 00:51:07,200
relaying the data

1376
00:51:10,950 --> 00:51:08,640
well uh

1377
00:51:12,790 --> 00:51:10,960
first yes we're going to be able to see

1378
00:51:14,549 --> 00:51:12,800
the rover where um

1379
00:51:17,190 --> 00:51:14,559
we've already got images planned for

1380
00:51:19,430 --> 00:51:17,200
later this week to to look at the rover

1381
00:51:20,950 --> 00:51:19,440
um and they they should

1382
00:51:23,030 --> 00:51:20,960
look great you know it's going to be

1383
00:51:23,910 --> 00:51:23,040
more than just a single pixel

1384
00:51:25,430 --> 00:51:23,920
um

1385
00:51:26,870 --> 00:51:25,440
and

1386
00:51:29,270 --> 00:51:26,880
we are

1387
00:51:32,470 --> 00:51:29,280
we've already done a lot of data

1388
00:51:34,390 --> 00:51:32,480
collection for the rover we've um we've

1389
00:51:36,470 --> 00:51:34,400
mapped out we've collected data across

1390
00:51:38,630 --> 00:51:36,480
the entire gale crater and the landing

1391
00:51:41,190 --> 00:51:38,640
ellipse and we've got stereo data and

1392
00:51:44,150 --> 00:51:41,200
color imagery

1393
00:51:48,150 --> 00:51:44,160
that are have already been used to start

1394
00:51:51,430 --> 00:51:48,160
looking at potential traverses and

1395
00:51:53,349 --> 00:51:51,440
as the mission goes on we are expecting

1396
00:51:55,589 --> 00:51:53,359
msl to come to us and say oh we need a

1397
00:51:58,630 --> 00:51:55,599
new picture there to make sure that

1398
00:52:00,950 --> 00:51:58,640
there's no new dust hazards or you know

1399
00:52:02,950 --> 00:52:00,960
it's a spot that you know maybe you want

1400
00:52:05,829 --> 00:52:02,960
a slightly better resolution at that

1401
00:52:09,109 --> 00:52:05,839
location so we um yes we're in in

1402
00:52:11,510 --> 00:52:09,119
addition to relaying the data um the the

1403
00:52:13,430 --> 00:52:11,520
cameras are expecting to help out

1404
00:52:14,950 --> 00:52:13,440
yeah i would reiterate that the mro data

1405
00:52:16,549 --> 00:52:14,960
that we have has been absolutely

1406
00:52:18,630 --> 00:52:16,559
critical to landing site selection you

1407
00:52:20,390 --> 00:52:18,640
know our ability to find safe flat spots

1408
00:52:22,790 --> 00:52:20,400
with relatively few rocks

1409
00:52:24,630 --> 00:52:22,800
um as mentioned we basically tiled all

1410
00:52:26,309 --> 00:52:24,640
the landing sites with landing you know

1411
00:52:29,270 --> 00:52:26,319
the potential landing ellipses with um

1412
00:52:30,870 --> 00:52:29,280
you know one meter type coverage

1413
00:52:32,549 --> 00:52:30,880
even stereo coverage

1414
00:52:34,069 --> 00:52:32,559
and uh and our rover drivers have

1415
00:52:35,510 --> 00:52:34,079
actually started to use those maps to

1416
00:52:37,510 --> 00:52:35,520
plan out long-term traverses you know

1417
00:52:38,390 --> 00:52:37,520
good candidate traverses and i think

1418
00:52:40,230 --> 00:52:38,400
there's an earlier question about

1419
00:52:41,670 --> 00:52:40,240
driving across dunes versus versus other

1420
00:52:43,270 --> 00:52:41,680
terrain and the river drivers actually

1421
00:52:44,950 --> 00:52:43,280
have algorithms that say you know it's

1422
00:52:46,549 --> 00:52:44,960
slow to go over dunes or it's dangerous

1423
00:52:49,190 --> 00:52:46,559
and it's fast to go over

1424
00:52:51,349 --> 00:52:49,200
um yeah um you know not non-sandy

1425
00:52:53,829 --> 00:52:51,359
surfaces flat surfaces and so they've

1426
00:52:55,430 --> 00:52:53,839
tried to up present some optimal options

1427
00:52:57,270 --> 00:52:55,440
you know optimal paths to the science

1428
00:52:58,790 --> 00:52:57,280
team to take a look at and they'll be

1429
00:53:00,470 --> 00:52:58,800
working closely with with the science

1430
00:53:02,390 --> 00:53:00,480
team and with john to to come up with

1431
00:53:03,990 --> 00:53:02,400
those with those drives and they're

1432
00:53:07,589 --> 00:53:04,000
up until now basically a hundred percent

1433
00:53:10,470 --> 00:53:07,599
based on uh on high-rise imagery

1434
00:53:12,630 --> 00:53:10,480
uh frank o'brien americaspace.com um so

1435
00:53:14,549 --> 00:53:12,640
now you have two roaring rovers on mars

1436
00:53:15,670 --> 00:53:14,559
and one of them has a tremendous amount

1437
00:53:17,829 --> 00:53:15,680
of data that you're going to be

1438
00:53:19,510 --> 00:53:17,839
expecting every day are you going to be

1439
00:53:21,510 --> 00:53:19,520
getting into situations where you're

1440
00:53:25,589 --> 00:53:21,520
going to have scheduling constraints on

1441
00:53:27,510 --> 00:53:25,599
the orbital relays or the dsn

1442
00:53:29,829 --> 00:53:27,520
no actually the orbiters are are able to

1443
00:53:31,990 --> 00:53:29,839
support both in fact um odyssey has two

1444
00:53:34,309 --> 00:53:32,000
partitions that uh that can cover the

1445
00:53:36,309 --> 00:53:34,319
largest paths that either mer or um or

1446
00:53:38,069 --> 00:53:36,319
msl can generate and so we think there's

1447
00:53:40,150 --> 00:53:38,079
very little conflict there

1448
00:53:42,470 --> 00:53:40,160
i just want to add

1449
00:53:44,710 --> 00:53:42,480
there also that the two rovers are in

1450
00:53:47,270 --> 00:53:44,720
different places on in such different

1451
00:53:49,910 --> 00:53:47,280
places that the timing of doing one

1452
00:53:51,349 --> 00:53:49,920
relay it's not going to interfere with

1453
00:53:53,670 --> 00:53:51,359
the other

1454
00:53:55,510 --> 00:53:53,680
okay leo's going to go next and he will

1455
00:53:57,829 --> 00:53:55,520
run that mic down your aisle there okay

1456
00:54:01,030 --> 00:53:57,839
leo go ahead

1457
00:54:04,150 --> 00:54:01,040
tv again i'm sorry if i have to ask mike

1458
00:54:06,950 --> 00:54:04,160
watkins to clarify his clarification

1459
00:54:09,270 --> 00:54:06,960
about the hga deploy you said nine

1460
00:54:11,109 --> 00:54:09,280
o'clock it's just i i can't do it in my

1461
00:54:13,030 --> 00:54:11,119
head the translation

1462
00:54:14,470 --> 00:54:13,040
you said nine o'clock local time for the

1463
00:54:15,829 --> 00:54:14,480
deploy but you're now saying something

1464
00:54:17,349 --> 00:54:15,839
different i wonder what that i said

1465
00:54:19,109 --> 00:54:17,359
afternoon

1466
00:54:20,470 --> 00:54:19,119
before and it actually ends in the early

1467
00:54:22,630 --> 00:54:20,480
afternoon rather than starts in the

1468
00:54:26,069 --> 00:54:22,640
afternoon so it starts around 11 o'clock

1469
00:54:28,150 --> 00:54:26,079
mars time and right now it is about

1470
00:54:30,390 --> 00:54:28,160
it's about 12 hours after landing so

1471
00:54:32,790 --> 00:54:30,400
it's about three o'clock in the morning

1472
00:54:34,870 --> 00:54:32,800
mar on mars right now so he's hours out

1473
00:54:36,630 --> 00:54:34,880
eight or nine hours from now yeah okay

1474
00:54:39,030 --> 00:54:36,640
and if i may just a quick question for

1475
00:54:41,030 --> 00:54:39,040
john grotzinger some light reading

1476
00:54:42,870 --> 00:54:41,040
perhaps since we now are going to get to

1477
00:54:45,430 --> 00:54:42,880
know this crater very well can you

1478
00:54:47,910 --> 00:54:45,440
recommend a paper that would kind of be

1479
00:54:49,109 --> 00:54:47,920
the definitive one to read while we uh

1480
00:54:51,190 --> 00:54:49,119
eat our

1481
00:54:53,430 --> 00:54:51,200
corn flakes

1482
00:54:55,270 --> 00:54:53,440
uh yeah i'm a little bleary and can't

1483
00:54:56,789 --> 00:54:55,280
just recite the references right now but

1484
00:54:58,789 --> 00:54:56,799
there there are some there are several

1485
00:55:00,630 --> 00:54:58,799
review papers that have been written and

1486
00:55:03,109 --> 00:55:00,640
uh if anybody sends me an email i'll be

1487
00:55:05,910 --> 00:55:03,119
happy to send those along

1488
00:55:07,349 --> 00:55:05,920
uh jonathan amos bbc again

1489
00:55:08,630 --> 00:55:07,359
you know the orientation of the rover

1490
00:55:10,230 --> 00:55:08,640
now so you know the orientation of the

1491
00:55:11,990 --> 00:55:10,240
mali camera

1492
00:55:16,390 --> 00:55:12,000
what is going to be in that

1493
00:55:21,829 --> 00:55:20,069
i actually do not know that

1494
00:55:23,670 --> 00:55:21,839
uh that's that's a good question i

1495
00:55:25,750 --> 00:55:23,680
should know the answer to that

1496
00:55:28,470 --> 00:55:25,760
um

1497
00:55:29,430 --> 00:55:28,480
we can quickly tell you that

1498
00:55:30,230 --> 00:55:29,440
yeah

1499
00:55:31,190 --> 00:55:30,240
but

1500
00:55:32,870 --> 00:55:31,200
after it's

1501
00:55:35,030 --> 00:55:32,880
looking out to the side

1502
00:55:36,630 --> 00:55:35,040
and so we had always hoped that the

1503
00:55:37,430 --> 00:55:36,640
rover might land with an orientation

1504
00:55:40,069 --> 00:55:37,440
where

1505
00:55:40,950 --> 00:55:40,079
uh molly might actually capture mount

1506
00:55:43,190 --> 00:55:40,960
sharp

1507
00:55:45,990 --> 00:55:43,200
and it's its potential that it would be

1508
00:55:47,829 --> 00:55:46,000
either oblique or uh toward the crater

1509
00:55:51,190 --> 00:55:47,839
rim i think it's going to be on the

1510
00:55:53,109 --> 00:55:51,200
flanks of of mount sharp and in and

1511
00:55:54,390 --> 00:55:53,119
create a rim

1512
00:55:55,910 --> 00:55:54,400
but it matters a little bit you know we

1513
00:55:58,069 --> 00:55:55,920
have this 112 degree azimuth plus or

1514
00:56:00,069 --> 00:55:58,079
minus 5 degrees or so it matters kind of

1515
00:56:02,309 --> 00:56:00,079
exactly where the how the flanks are and

1516
00:56:03,510 --> 00:56:02,319
where the central peak is and i think we

1517
00:56:04,630 --> 00:56:03,520
probably could get a better answer for

1518
00:56:06,230 --> 00:56:04,640
you uh

1519
00:56:07,589 --> 00:56:06,240
relatively quickly you'll see it

1520
00:56:11,109 --> 00:56:07,599
tomorrow at this time at the press

1521
00:56:16,549 --> 00:56:14,230
hi eric ham with nature again um so

1522
00:56:18,230 --> 00:56:16,559
let's assume that miguel's uh tracking

1523
00:56:19,990 --> 00:56:18,240
data for the moment is correct and that

1524
00:56:22,470 --> 00:56:20,000
you've landed

1525
00:56:23,910 --> 00:56:22,480
two kilometers or so down track a little

1526
00:56:25,109 --> 00:56:23,920
bit closer to mount sharp than you

1527
00:56:27,030 --> 00:56:25,119
expected

1528
00:56:28,309 --> 00:56:27,040
uh so switch on my questions for you

1529
00:56:29,510 --> 00:56:28,319
behind you

1530
00:56:30,549 --> 00:56:29,520
you have where you thought you were

1531
00:56:32,069 --> 00:56:30,559
going to land

1532
00:56:33,190 --> 00:56:32,079
you know the foot of the alluvial fan

1533
00:56:35,190 --> 00:56:33,200
with those interesting thermal

1534
00:56:36,390 --> 00:56:35,200
properties and in front of you is your

1535
00:56:38,309 --> 00:56:36,400
main target

1536
00:56:39,990 --> 00:56:38,319
so are you going to go in reverse are

1537
00:56:42,630 --> 00:56:40,000
you going to go ahead

1538
00:56:45,670 --> 00:56:42,640
well i i you know the the boundary

1539
00:56:49,349 --> 00:56:45,680
between where the alluvial fan ends and

1540
00:56:51,670 --> 00:56:49,359
the base amount sharp is is diffuse

1541
00:56:54,150 --> 00:56:51,680
all alluvial fans ultimately taper out

1542
00:56:55,910 --> 00:56:54,160
and they they find in grain size

1543
00:56:57,750 --> 00:56:55,920
and and we really want to be on the

1544
00:56:59,589 --> 00:56:57,760
downslope side of that if that's what's

1545
00:57:01,589 --> 00:56:59,599
going on there so

1546
00:57:04,309 --> 00:57:01,599
what we're the goal of the crowd

1547
00:57:07,510 --> 00:57:04,319
sourcing mapping exercise was to be able

1548
00:57:10,150 --> 00:57:07,520
to compile a map that that made a first

1549
00:57:13,990 --> 00:57:10,160
crack at sort of units different types

1550
00:57:16,870 --> 00:57:14,000
of geological units but also iding key

1551
00:57:18,470 --> 00:57:16,880
bits of outcrop maybe the height of of

1552
00:57:20,789 --> 00:57:18,480
the podium here

1553
00:57:22,630 --> 00:57:20,799
a meter two meters maybe three meters

1554
00:57:24,950 --> 00:57:22,640
that things that would would that

1555
00:57:27,910 --> 00:57:24,960
constituted part of that one percent edl

1556
00:57:29,910 --> 00:57:27,920
risk that's what we're after and so what

1557
00:57:31,589 --> 00:57:29,920
we would do is string together a pathway

1558
00:57:33,270 --> 00:57:31,599
that would link us between these and if

1559
00:57:35,349 --> 00:57:33,280
it takes us back towards the fan then

1560
00:57:38,069 --> 00:57:35,359
we'll go that way and if it takes us

1561
00:57:39,990 --> 00:57:38,079
forward then we'll go that way too so

1562
00:57:42,230 --> 00:57:40,000
you know most geological mapping

1563
00:57:43,910 --> 00:57:42,240
exercises do not involve a traverse in

1564
00:57:45,750 --> 00:57:43,920
just one straight direction and our goal

1565
00:57:47,910 --> 00:57:45,760
is not just to head for the hills what

1566
00:57:49,510 --> 00:57:47,920
are the size of these uh boulders that

1567
00:57:50,950 --> 00:57:49,520
you want to string together

1568
00:57:53,190 --> 00:57:50,960
uh well you know each one of these

1569
00:57:56,390 --> 00:57:53,200
quadrangles is roughly about one and a

1570
00:57:58,789 --> 00:57:56,400
half kilometers on a side and within

1571
00:57:59,829 --> 00:57:58,799
every one of them there is some kind of

1572
00:58:01,589 --> 00:57:59,839
a scarp

1573
00:58:04,549 --> 00:58:01,599
and so what we're trying to do is to

1574
00:58:06,470 --> 00:58:04,559
piece together a stratigraphic section

1575
00:58:08,630 --> 00:58:06,480
of the landing ellipse

1576
00:58:11,510 --> 00:58:08,640
using the mapping is an efficient way to

1577
00:58:13,109 --> 00:58:11,520
go around and check all of the points

1578
00:58:14,630 --> 00:58:13,119
that would contribute towards that

1579
00:58:16,150 --> 00:58:14,640
stratigraphy

1580
00:58:17,430 --> 00:58:16,160
and uh

1581
00:58:18,390 --> 00:58:17,440
probably

1582
00:58:20,470 --> 00:58:18,400
speaking you said you were trying to

1583
00:58:21,910 --> 00:58:20,480
string together certain objects

1584
00:58:25,430 --> 00:58:21,920
in your path what are those options we

1585
00:58:27,030 --> 00:58:25,440
don't know yet stay tuned yeah

1586
00:58:29,750 --> 00:58:27,040
okay

1587
00:58:31,990 --> 00:58:29,760
guy norris from aviation week uh i'm not

1588
00:58:34,390 --> 00:58:32,000
sure who exactly can handle this space

1589
00:58:36,390 --> 00:58:34,400
but um under the

1590
00:58:38,069 --> 00:58:36,400
nominal uh commissioning

1591
00:58:38,950 --> 00:58:38,079
uh schedule that you do have at the

1592
00:58:41,349 --> 00:58:38,960
moment

1593
00:58:44,390 --> 00:58:41,359
when could we expect the first motion

1594
00:58:46,069 --> 00:58:44,400
for the vehicle to be commanded and um

1595
00:58:47,829 --> 00:58:46,079
secondly really is the vehicle at the

1596
00:58:50,150 --> 00:58:47,839
moment they're over does it is it

1597
00:58:52,230 --> 00:58:50,160
configured essentially how the model is

1598
00:58:54,710 --> 00:58:52,240
right now with the uh center set of

1599
00:58:55,829 --> 00:58:54,720
wheels in the stowed position

1600
00:58:58,150 --> 00:58:55,839
thanks

1601
00:59:00,309 --> 00:58:58,160
um so it is no it's actually seeing it's

1602
00:59:01,910 --> 00:59:00,319
sitting flat right now so it hears up on

1603
00:59:03,670 --> 00:59:01,920
a podium it's actually sitting quite you

1604
00:59:04,470 --> 00:59:03,680
know it's sitting quite flat like this

1605
00:59:07,510 --> 00:59:04,480
now

1606
00:59:09,030 --> 00:59:07,520
uh with the with the rsm down and the hd

1607
00:59:10,789 --> 00:59:09,040
about to come out so it's sitting i

1608
00:59:12,789 --> 00:59:10,799
can't lift it up without the with the

1609
00:59:15,109 --> 00:59:12,799
system changing but it's

1610
00:59:16,870 --> 00:59:15,119
going to do it this way

1611
00:59:18,470 --> 00:59:16,880
right it's it's sitting quite flat now

1612
00:59:20,390 --> 00:59:18,480
as far as we can tell we do within you

1613
00:59:22,549 --> 00:59:20,400
know a couple of degrees right

1614
00:59:27,109 --> 00:59:22,559
um and what was the other question first

1615
00:59:28,630 --> 00:59:27,119
drive uh i would say a couple of weeks

1616
00:59:30,789 --> 00:59:28,640
is

1617
00:59:32,390 --> 00:59:30,799
a good number for that

1618
00:59:39,510 --> 00:59:32,400
and it will be quite a short drive you

1619
00:59:43,030 --> 00:59:40,950
scientists i have a question for sarah

1620
00:59:45,190 --> 00:59:43,040
and then one for everyone here um will

1621
00:59:46,470 --> 00:59:45,200
highrise be able to see the craters of

1622
00:59:50,309 --> 00:59:46,480
the ballast made

1623
00:59:50,319 --> 00:59:54,309
i'm not sure

1624
00:59:57,349 --> 00:59:56,069
we are

1625
00:59:59,430 --> 00:59:57,359
going to be

1626
01:00:03,030 --> 00:59:59,440
looking for the various hardware

1627
01:00:04,150 --> 01:00:03,040
components in future images and

1628
01:00:05,589 --> 01:00:04,160
you know i

1629
01:00:07,190 --> 01:00:05,599
don't know i don't know what we're going

1630
01:00:09,030 --> 01:00:07,200
to see

1631
01:00:10,870 --> 01:00:09,040
and then for all of you i heard you're

1632
01:00:12,950 --> 01:00:10,880
going to be living on mars time for the

1633
01:00:15,109 --> 01:00:12,960
first 90 souls is that right

1634
01:00:17,910 --> 01:00:15,119
um and how come only for 90 souls and

1635
01:00:18,789 --> 01:00:17,920
then what happens after that

1636
01:00:20,549 --> 01:00:18,799
well

1637
01:00:22,549 --> 01:00:20,559
that's a good question that yeah that's

1638
01:00:24,150 --> 01:00:22,559
a good question uh and and i'll answer

1639
01:00:25,990 --> 01:00:24,160
that i was joking with with gentry just

1640
01:00:27,670 --> 01:00:26,000
before this that you can tell who was

1641
01:00:30,630 --> 01:00:27,680
working on a mars time here at night but

1642
01:00:32,549 --> 01:00:30,640
who's still wearing the landing shirt

1643
01:00:34,230 --> 01:00:32,559
john

1644
01:00:35,589 --> 01:00:34,240
um

1645
01:00:36,390 --> 01:00:35,599
you know the thing about these missions

1646
01:00:39,750 --> 01:00:36,400
are

1647
01:00:42,470 --> 01:00:39,760
have to learn how to use this very

1648
01:00:43,990 --> 01:00:42,480
complicated machine that we've built

1649
01:00:45,829 --> 01:00:44,000
and it's in a new environment and it

1650
01:00:47,589 --> 01:00:45,839
behaves differently than than it did in

1651
01:00:48,870 --> 01:00:47,599
the test bed here you know it's got

1652
01:00:51,270 --> 01:00:48,880
different gravity it's got different

1653
01:00:52,630 --> 01:00:51,280
temperatures it's got everything

1654
01:00:54,230 --> 01:00:52,640
you know different from exactly the way

1655
01:00:55,430 --> 01:00:54,240
we tested it and we tested a range of

1656
01:00:56,870 --> 01:00:55,440
activities but you have to find out

1657
01:00:59,190 --> 01:00:56,880
exactly how it's going to behave when

1658
01:01:00,789 --> 01:00:59,200
you're when you're at mars

1659
01:01:02,309 --> 01:01:00,799
and and we need to get comfortable with

1660
01:01:03,990 --> 01:01:02,319
that we need to do that efficiently so

1661
01:01:05,589 --> 01:01:04,000
we want to run through our paces in an

1662
01:01:07,990 --> 01:01:05,599
efficient way

1663
01:01:11,349 --> 01:01:08,000
and by working mars time and it gives us

1664
01:01:13,109 --> 01:01:11,359
basically 16 hours to plan an uplink

1665
01:01:14,069 --> 01:01:13,119
while the rover is sleeping at night on

1666
01:01:16,150 --> 01:01:14,079
mars

1667
01:01:17,910 --> 01:01:16,160
so so we can take a long time and of

1668
01:01:19,589 --> 01:01:17,920
course if we don't rotate with the mars

1669
01:01:21,670 --> 01:01:19,599
day and night then we start to lose time

1670
01:01:24,390 --> 01:01:21,680
we start to lose that that ability to to

1671
01:01:26,470 --> 01:01:24,400
keep track of of the mars night while we

1672
01:01:29,270 --> 01:01:26,480
were working

1673
01:01:30,789 --> 01:01:29,280
now that that is to help us be efficient

1674
01:01:32,150 --> 01:01:30,799
in checking out the vehicle but there's

1675
01:01:33,829 --> 01:01:32,160
another complex thing that we have to

1676
01:01:35,710 --> 01:01:33,839
learn and that's how to operate with

1677
01:01:37,910 --> 01:01:35,720
ourselves we have

1678
01:01:40,150 --> 01:01:37,920
420 people or something i forget the

1679
01:01:43,109 --> 01:01:40,160
number john

1680
01:01:45,829 --> 01:01:43,119
yeah 400 scientists on the mission and

1681
01:01:47,510 --> 01:01:45,839
another 300 or more engineers on the

1682
01:01:49,109 --> 01:01:47,520
mission so we have something like 700 or

1683
01:01:51,030 --> 01:01:49,119
800 people

1684
01:01:52,710 --> 01:01:51,040
learning to operate this vehicle

1685
01:01:54,230 --> 01:01:52,720
and we have to know how to interact with

1686
01:01:55,910 --> 01:01:54,240
ourselves we have to know each other's

1687
01:01:57,029 --> 01:01:55,920
voices we have to know how each other

1688
01:01:57,910 --> 01:01:57,039
operates and we have to learn each

1689
01:02:00,150 --> 01:01:57,920
other's

1690
01:02:02,470 --> 01:02:00,160
individual specialized skills so that we

1691
01:02:04,150 --> 01:02:02,480
can get more efficient in the future

1692
01:02:05,990 --> 01:02:04,160
so after this 90 day period we get to

1693
01:02:07,109 --> 01:02:06,000
know each other very well then we can

1694
01:02:08,630 --> 01:02:07,119
send folks back to their home

1695
01:02:10,150 --> 01:02:08,640
institution and go back to france and go

1696
01:02:12,069 --> 01:02:10,160
back to spain and go back to goddard and

1697
01:02:13,270 --> 01:02:12,079
go back to places like that work a more

1698
01:02:15,270 --> 01:02:13,280
normal time

1699
01:02:17,349 --> 01:02:15,280
operate by the internet operate by

1700
01:02:19,109 --> 01:02:17,359
telecon and we know those people and

1701
01:02:20,549 --> 01:02:19,119
they know us and they know the rover

1702
01:02:22,789 --> 01:02:20,559
they know the software systems and we'll

1703
01:02:24,390 --> 01:02:22,799
be much more efficient so this is really

1704
01:02:25,349 --> 01:02:24,400
kind of a you know uh

1705
01:02:31,349 --> 01:02:25,359
uh

1706
01:02:33,829 --> 01:02:31,359
learning both how to operate the vehicle

1707
01:02:35,510 --> 01:02:33,839
and and how to interact with each other

1708
01:02:38,150 --> 01:02:35,520
let me just add one more thing to that

1709
01:02:41,430 --> 01:02:38,160
as if uh it wasn't challenging enough to

1710
01:02:43,750 --> 01:02:41,440
work on mars time on mer

1711
01:02:45,910 --> 01:02:43,760
at the end of the saw we have a

1712
01:02:48,069 --> 01:02:45,920
x-band link to earth to send all the

1713
01:02:51,029 --> 01:02:48,079
critical data back

1714
01:02:52,150 --> 01:02:51,039
and that could be scheduled exactly on

1715
01:02:53,990 --> 01:02:52,160
on time

1716
01:02:57,109 --> 01:02:54,000
on on this mission because of the larger

1717
01:02:58,789 --> 01:02:57,119
data volume we need to grab an mro or an

1718
01:03:00,950 --> 01:02:58,799
odyssey pass

1719
01:03:03,349 --> 01:03:00,960
and so you the way to think about it is

1720
01:03:06,150 --> 01:03:03,359
a mars time rotation of 39 minutes every

1721
01:03:08,230 --> 01:03:06,160
day but now add plus or minus an hour

1722
01:03:09,829 --> 01:03:08,240
and a half to randomize your schedule

1723
01:03:11,430 --> 01:03:09,839
just to make sure that anybody you

1724
01:03:15,990 --> 01:03:11,440
wanted to have a relationship here on

1725
01:03:18,470 --> 01:03:17,270
it's also great the way we're starting

1726
01:03:19,589 --> 01:03:18,480
you know people talk about it being like

1727
01:03:23,109 --> 01:03:19,599
jet lag

1728
01:03:25,349 --> 01:03:23,119
certain sense we're off by by you know

1729
01:03:26,710 --> 01:03:25,359
12 hours now except that it's also

1730
01:03:28,230 --> 01:03:26,720
daylight when you're trying to sleep so

1731
01:03:29,670 --> 01:03:28,240
at least when you fly to another country

1732
01:03:30,710 --> 01:03:29,680
and you have jet lag it's night time and

1733
01:03:33,109 --> 01:03:30,720
you're trying to go to sleep at night

1734
01:03:34,470 --> 01:03:33,119
and here we were exactly out of sync so

1735
01:03:36,470 --> 01:03:34,480
so we're starting off in kind of the

1736
01:03:37,910 --> 01:03:36,480
worst time but uh but it should actually

1737
01:03:40,309 --> 01:03:37,920
get a little easier here over the next

1738
01:03:42,309 --> 01:03:40,319
uh next few weeks

1739
01:03:43,510 --> 01:03:42,319
okay uh henry has a microphone and then

1740
01:03:45,510 --> 01:03:43,520
i know there are a few questions coming

1741
01:03:47,589 --> 01:03:45,520
forward again so go ahead henry

1742
01:03:49,109 --> 01:03:47,599
question uh henry bortmann astro biology

1743
01:03:52,069 --> 01:03:49,119
magazine quick question about the

1744
01:03:54,789 --> 01:03:52,079
martian calendar does sol zero start at

1745
01:03:59,190 --> 01:03:54,799
touchdown or at local midnight at the

1746
01:03:59,200 --> 01:04:03,029
local midnight

1747
01:04:07,750 --> 01:04:05,430
uh someone else on this end um todd and

1748
01:04:09,910 --> 01:04:07,760
then we'll just keep moving forward

1749
01:04:12,870 --> 01:04:09,920
um todd halverson of florida today in

1750
01:04:15,430 --> 01:04:12,880
usa today i might have missed this but

1751
01:04:18,630 --> 01:04:15,440
um could you tell us what configuration

1752
01:04:19,430 --> 01:04:18,640
the vehicle is in in the picture behind

1753
01:04:22,230 --> 01:04:19,440
you

1754
01:04:25,190 --> 01:04:22,240
is the heat shield still on there and is

1755
01:04:27,270 --> 01:04:25,200
that what the white albedo is there

1756
01:04:30,549 --> 01:04:27,280
and i was also wondering if you could

1757
01:04:33,109 --> 01:04:30,559
address the historic nature of uh

1758
01:04:34,630 --> 01:04:33,119
of what went on last night and how you

1759
01:04:35,750 --> 01:04:34,640
think this will be

1760
01:04:38,069 --> 01:04:35,760
viewed

1761
01:04:41,109 --> 01:04:38,079
10 years from now 20 years from now 50

1762
01:04:42,069 --> 01:04:41,119
years from now thanks uh

1763
01:04:51,029 --> 01:04:42,079
i

1764
01:04:51,039 --> 01:04:55,349
we don't know for sure yet

1765
01:04:59,589 --> 01:04:57,750
but by time i mean

1766
01:05:02,069 --> 01:04:59,599
yeah we need to do the reconstruction i

1767
01:05:03,589 --> 01:05:02,079
think i think the white thing steve yeah

1768
01:05:04,870 --> 01:05:03,599
yeah that's the back shelf

1769
01:05:06,549 --> 01:05:04,880
you're looking at the top of the back

1770
01:05:07,910 --> 01:05:06,559
shelf right there would be underneath so

1771
01:05:09,990 --> 01:05:07,920
it's not easy to see these images

1772
01:05:11,349 --> 01:05:10,000
whether or not it's off or not so

1773
01:05:15,109 --> 01:05:11,359
we'd only know by timing and we don't

1774
01:05:19,430 --> 01:05:17,270
i'm from a

1775
01:05:21,270 --> 01:05:19,440
i mean from a philosophical point of

1776
01:05:23,829 --> 01:05:21,280
view i mean the fact that we see

1777
01:05:25,910 --> 01:05:23,839
ourselves arriving to another

1778
01:05:27,910 --> 01:05:25,920
planet you know just like phoenix did

1779
01:05:29,990 --> 01:05:27,920
first i mean it's just mind-boggling to

1780
01:05:31,670 --> 01:05:30,000
me i think to out to all of us so i mean

1781
01:05:36,230 --> 01:05:31,680
i cannot say more than that it's just

1782
01:05:40,230 --> 01:05:38,470
move forward one more here

1783
01:05:41,829 --> 01:05:40,240
uh kelly b sky and telescope i was

1784
01:05:44,870 --> 01:05:41,839
outside for a bit so i apologize if this

1785
01:05:46,150 --> 01:05:44,880
has been asked 140 gram kilograms of

1786
01:05:48,950 --> 01:05:46,160
hydrazine

1787
01:05:51,589 --> 01:05:48,960
is that a concern did you have the

1788
01:05:53,109 --> 01:05:51,599
flyway be in the downwind prevailing

1789
01:05:54,789 --> 01:05:53,119
wind direction can you talk to that a

1790
01:05:56,710 --> 01:05:54,799
bit

1791
01:05:58,390 --> 01:05:56,720
well

1792
01:06:00,789 --> 01:05:58,400
i could not tell you about the wind i

1793
01:06:03,270 --> 01:06:00,799
mean it was the choice to to fly it as

1794
01:06:05,750 --> 01:06:03,280
far as possible

1795
01:06:06,470 --> 01:06:05,760
well it's the direction is i said we

1796
01:06:09,349 --> 01:06:06,480
have

1797
01:06:10,870 --> 01:06:09,359
limited control okay so it's you draw a

1798
01:06:13,589 --> 01:06:10,880
line east-west

1799
01:06:16,309 --> 01:06:13,599
and fly north of that line depending on

1800
01:06:18,470 --> 01:06:16,319
what orientation the descent stage

1801
01:06:20,630 --> 01:06:18,480
it's uh it finds itself

1802
01:06:21,750 --> 01:06:20,640
the reason for that is that we do a

1803
01:06:42,950 --> 01:06:21,760
a

1804
01:06:46,789 --> 01:06:42,960
so

1805
01:06:49,510 --> 01:06:46,799
choices either go that way or that way

1806
01:06:50,870 --> 01:06:49,520
and so we choose the one that goes

1807
01:06:52,630 --> 01:06:50,880
north

1808
01:06:55,910 --> 01:06:52,640
okay so when we do our simulations

1809
01:06:59,190 --> 01:06:55,920
you'll see a whole bunch of dots

1810
01:07:03,670 --> 01:06:59,200
on the north northern hemisphere of the

1811
01:07:06,630 --> 01:07:03,680
of of of the two north quadrants

1812
01:07:09,190 --> 01:07:06,640
of so that's that's what we do now that

1813
01:07:11,589 --> 01:07:09,200
was picked up between the scientists

1814
01:07:12,710 --> 01:07:11,599
and the engineers looking for all the

1815
01:07:16,710 --> 01:07:12,720
conditions

1816
01:07:20,870 --> 01:07:19,109
okay let's go to irene again

1817
01:07:22,549 --> 01:07:20,880
oh i'm sorry you know irene kicked the

1818
01:07:24,470 --> 01:07:22,559
mic but we have a question back here

1819
01:07:26,950 --> 01:07:24,480
first that we'll take thank you jackie

1820
01:07:29,029 --> 01:07:26,960
goddard for the times of london um i

1821
01:07:30,270 --> 01:07:29,039
just wanted to clarify first with sarah

1822
01:07:33,430 --> 01:07:30,280
when you say

1823
01:07:35,750 --> 01:07:33,440
340 kilometers away

1824
01:07:38,870 --> 01:07:35,760
uh that that image was taken is that

1825
01:07:40,950 --> 01:07:38,880
direct uh vertical altitude and then my

1826
01:07:44,150 --> 01:07:40,960
second question just um from mike

1827
01:07:46,069 --> 01:07:44,160
watkins to the untrained eye um these

1828
01:07:49,670 --> 01:07:46,079
are pictures of black and white pictures

1829
01:07:51,470 --> 01:07:49,680
of of gravel um to the trained eye can

1830
01:07:54,309 --> 01:07:51,480
you sum up just how

1831
01:07:58,069 --> 01:07:54,319
sophisticated and exciting and momentous

1832
01:08:03,430 --> 01:07:59,670
okay the um

1833
01:08:07,829 --> 01:08:03,440
it's the 340 kilometers is line of sight

1834
01:08:09,430 --> 01:08:07,839
so it's not i think yeah we were

1835
01:08:12,549 --> 01:08:09,440
we were almost

1836
01:08:15,270 --> 01:08:12,559
directly overhead i think we had a very

1837
01:08:19,749 --> 01:08:15,280
very small angle it was but it was it

1838
01:08:23,749 --> 01:08:21,669
um i'll take a crack at the photos and

1839
01:08:25,110 --> 01:08:23,759
i'll let john

1840
01:08:27,510 --> 01:08:25,120
take a better crack from the scientific

1841
01:08:29,510 --> 01:08:27,520
perspective you know you know to me it

1842
01:08:31,110 --> 01:08:29,520
it's representative of

1843
01:08:33,990 --> 01:08:31,120
of of course a successful landing on

1844
01:08:36,950 --> 01:08:34,000
mars it's representative of

1845
01:08:39,110 --> 01:08:36,960
of a new home of of further over it's

1846
01:08:41,590 --> 01:08:39,120
representative of of a new mars that we

1847
01:08:43,430 --> 01:08:41,600
have never seen before and so every one

1848
01:08:46,950 --> 01:08:43,440
of those pictures is the most beautiful

1849
01:08:51,349 --> 01:08:48,630
i think john would say this better than

1850
01:08:53,829 --> 01:08:51,359
i would that if those if those pieces of

1851
01:08:55,510 --> 01:08:53,839
gravel are transported by water on mars

1852
01:08:57,110 --> 01:08:55,520
and ancient mars then they're much more

1853
01:08:58,630 --> 01:08:57,120
than gravel but john you should pick up

1854
01:09:00,070 --> 01:08:58,640
from there

1855
01:09:00,870 --> 01:09:00,080
thanks for setting me up

1856
01:09:02,149 --> 01:09:00,880
uh

1857
01:09:04,070 --> 01:09:02,159
you know i

1858
01:09:06,229 --> 01:09:04,080
uh a minute ago there was a there was a

1859
01:09:10,149 --> 01:09:06,239
question down here about about what this

1860
01:09:11,910 --> 01:09:10,159
this mission means to you and uh and i

1861
01:09:13,269 --> 01:09:11,920
i think for us at this point as

1862
01:09:15,189 --> 01:09:13,279
scientists

1863
01:09:17,829 --> 01:09:15,199
we haven't even scratched the surface

1864
01:09:19,910 --> 01:09:17,839
and and really what's amazing about it

1865
01:09:21,510 --> 01:09:19,920
is the miracle of this engineering

1866
01:09:23,189 --> 01:09:21,520
that's all you can do is sit there as a

1867
01:09:24,789 --> 01:09:23,199
member of the science team and don

1868
01:09:26,070 --> 01:09:24,799
hassler is a pi the rad instrument he's

1869
01:09:29,030 --> 01:09:26,080
sitting behind you there he's not in his

1870
01:09:31,349 --> 01:09:29,040
head it is a miracle to us that we have

1871
01:09:33,430 --> 01:09:31,359
chosen this place as a result of

1872
01:09:35,349 --> 01:09:33,440
scientific deliberation

1873
01:09:36,709 --> 01:09:35,359
this edl system

1874
01:09:39,269 --> 01:09:36,719
for the first time in the history of

1875
01:09:41,829 --> 01:09:39,279
land admissions allowed the science

1876
01:09:43,590 --> 01:09:41,839
community to choose between four options

1877
01:09:45,349 --> 01:09:43,600
none were excluded by engineering the

1878
01:09:47,030 --> 01:09:45,359
final four was a debate

1879
01:09:49,430 --> 01:09:47,040
of of scientists that like different

1880
01:09:51,910 --> 01:09:49,440
flavors of chocolate and vanilla

1881
01:09:55,510 --> 01:09:51,920
and and then when it comes down to

1882
01:09:57,590 --> 01:09:55,520
creating a a priority of of images to

1883
01:09:59,990 --> 01:09:57,600
downlink and you have your choice of the

1884
01:10:01,750 --> 01:10:00,000
front haz cam and the rear has cam the

1885
01:10:03,030 --> 01:10:01,760
most amazing thing about it to get back

1886
01:10:04,470 --> 01:10:03,040
to one of the things that emily was

1887
01:10:06,390 --> 01:10:04,480
pointing at you have a group of

1888
01:10:08,149 --> 01:10:06,400
engineers and a group of scientists and

1889
01:10:10,310 --> 01:10:08,159
here's what happened

1890
01:10:13,030 --> 01:10:10,320
jennifer trosper comes up to me and says

1891
01:10:15,110 --> 01:10:13,040
john we we really need to get the

1892
01:10:16,550 --> 01:10:15,120
engineering state of health data down

1893
01:10:18,070 --> 01:10:16,560
that's a top priority and i said of

1894
01:10:20,070 --> 01:10:18,080
course i agree

1895
01:10:22,070 --> 01:10:20,080
and we think we might be able to sneak

1896
01:10:24,070 --> 01:10:22,080
in an image what would be your first

1897
01:10:26,070 --> 01:10:24,080
choice would it be the front haz cam or

1898
01:10:28,950 --> 01:10:26,080
the rear haz cam

1899
01:10:31,189 --> 01:10:28,960
and all of the scientists

1900
01:10:32,709 --> 01:10:31,199
wanted the rear haz cam

1901
01:10:34,870 --> 01:10:32,719
and all the engineers wanted the front

1902
01:10:36,390 --> 01:10:34,880
has cam and the reason for that is they

1903
01:10:37,750 --> 01:10:36,400
said well there's no obstructions in the

1904
01:10:39,510 --> 01:10:37,760
way the wheels aren't in the way it's

1905
01:10:41,350 --> 01:10:39,520
the most open view of the terrain isn't

1906
01:10:43,030 --> 01:10:41,360
that what you would want and all the

1907
01:10:44,630 --> 01:10:43,040
scientists said no we want to see the

1908
01:10:46,229 --> 01:10:44,640
wheel on the ground because this is not

1909
01:10:48,310 --> 01:10:46,239
a moment for science it's a moment for

1910
01:10:50,229 --> 01:10:48,320
engineering and when you see that wheel

1911
01:10:52,870 --> 01:10:50,239
on the ground you know you've landed on

1912
01:10:54,870 --> 01:10:52,880
mars no semaphore tones no people

1913
01:10:56,310 --> 01:10:54,880
jumping up and down you actually see a

1914
01:10:58,149 --> 01:10:56,320
picture of the surface of the planet

1915
01:11:03,750 --> 01:10:58,159
with a spacecraft on it and that is the

1916
01:11:08,550 --> 01:11:06,070
thoughts with the reuters um i'm not

1917
01:11:10,470 --> 01:11:08,560
sure who to ask this to and please don't

1918
01:11:12,310 --> 01:11:10,480
laugh if it's really silly but with the

1919
01:11:14,630 --> 01:11:12,320
nuclear power source could you just

1920
01:11:17,430 --> 01:11:14,640
explain a little bit about why uh

1921
01:11:20,149 --> 01:11:17,440
daytime and nighttime and rover sleep is

1922
01:11:22,390 --> 01:11:20,159
is important or a factor

1923
01:11:25,189 --> 01:11:22,400
um sure and it's maybe not quite as

1924
01:11:28,070 --> 01:11:25,199
obvious as is it's certainly not a silly

1925
01:11:31,110 --> 01:11:28,080
question at all so the the rtg generates

1926
01:11:33,510 --> 01:11:31,120
just a little bit of electricity

1927
01:11:36,070 --> 01:11:33,520
and we think of it as a as a trickle

1928
01:11:38,950 --> 01:11:36,080
charger of our batteries and we are

1929
01:11:40,390 --> 01:11:38,960
always operating on the batteries

1930
01:11:42,470 --> 01:11:40,400
during the day and at night we're

1931
01:11:44,390 --> 01:11:42,480
trickle charging them back

1932
01:11:46,790 --> 01:11:44,400
the other big advantage is it generates

1933
01:11:48,790 --> 01:11:46,800
a lot of heat most of what the rtg

1934
01:11:50,149 --> 01:11:48,800
generates is heat

1935
01:11:51,750 --> 01:11:50,159
we take a little bit of that heat with a

1936
01:11:55,910 --> 01:11:51,760
thermocouple and make a little bit of

1937
01:11:58,229 --> 01:11:55,920
electricity you know a 100 watts or so

1938
01:11:59,910 --> 01:11:58,239
but that heat keeps us warm it prevents

1939
01:12:02,070 --> 01:11:59,920
us from having to use a lot of heaters

1940
01:12:03,350 --> 01:12:02,080
electrical heaters for for warmth so you

1941
01:12:05,189 --> 01:12:03,360
know we circulate

1942
01:12:06,470 --> 01:12:05,199
fluid a fluid loop you know you think of

1943
01:12:07,430 --> 01:12:06,480
it like a freon loop or something an air

1944
01:12:09,510 --> 01:12:07,440
conditioner

1945
01:12:11,750 --> 01:12:09,520
to take that heat and and and pump it

1946
01:12:12,709 --> 01:12:11,760
around the rover body and keep the rover

1947
01:12:14,950 --> 01:12:12,719
warm

1948
01:12:16,470 --> 01:12:14,960
so uh you know we still need that that

1949
01:12:17,830 --> 01:12:16,480
that's where most of the energy goes and

1950
01:12:19,110 --> 01:12:17,840
the rest of it trickle charges our

1951
01:12:20,390 --> 01:12:19,120
batteries and we use the batteries

1952
01:12:22,550 --> 01:12:20,400
during the day

1953
01:12:24,310 --> 01:12:22,560
and that's not a as big limitation as

1954
01:12:25,750 --> 01:12:24,320
you think because of course we we want

1955
01:12:26,870 --> 01:12:25,760
to take pictures and we want to see what

1956
01:12:28,390 --> 01:12:26,880
we're doing and we want to look at the

1957
01:12:29,669 --> 01:12:28,400
workspace and look at rocks and pick

1958
01:12:31,910 --> 01:12:29,679
targets out and you want to do those

1959
01:12:33,830 --> 01:12:31,920
things during the day and not at night

1960
01:12:35,110 --> 01:12:33,840
it's warmer during the day so it really

1961
01:12:36,709 --> 01:12:35,120
fits pretty naturally that the

1962
01:12:39,030 --> 01:12:36,719
operations concept that you that you'd

1963
01:12:40,870 --> 01:12:39,040
want to do

1964
01:12:42,390 --> 01:12:40,880
all right we're going to end the press

1965
01:12:43,750 --> 01:12:42,400
briefing for today of course those of

1966
01:12:46,310 --> 01:12:43,760
you in the room can come up and ask some

1967
01:12:48,709 --> 01:12:46,320
more questions afterwards as a reminder

1968
01:12:49,990 --> 01:12:48,719
i already mentioned 4 o'clock today we

1969
01:12:52,790 --> 01:12:50,000
hope to do that follow-up news

1970
01:12:55,270 --> 01:12:52,800
conference with marty images after today

1971
01:12:57,590 --> 01:12:55,280
we will do daily 10 a.m news conferences

1972
01:12:58,950 --> 01:12:57,600
so please join us for those and

1973
01:13:01,590 --> 01:12:58,960
if you want to stay in your seats we're

1974
01:13:03,510 --> 01:13:01,600
going to take one look again at what it

1975
01:13:04,870 --> 01:13:03,520
was like in mission control last night

1976
01:13:15,910 --> 01:13:04,880
at 10 30.

1977
01:13:22,149 --> 01:13:18,470
things are looking good coming up on the

1978
01:13:22,159 --> 01:13:27,510
we'll report sentry interface

1979
01:13:30,070 --> 01:13:28,950
we're not beginning to feel the

1980
01:13:32,950 --> 01:13:30,080
atmosphere

1981
01:13:35,510 --> 01:13:32,960
as we go in here uh it is reporting that

1982
01:13:39,430 --> 01:13:35,520
we are seeing g's on the order of uh 11

1983
01:13:42,390 --> 01:13:41,110
2 is starting

1984
01:13:46,470 --> 01:13:42,400
we are now getting telemetry from

1985
01:13:53,270 --> 01:13:47,830
we should have parachute deploy around

1986
01:13:53,280 --> 01:13:56,470
the parachute is deployed

1987
01:13:56,480 --> 01:14:01,990
we are decelerating

1988
01:14:08,470 --> 01:14:03,590
we're down to 90 meters per second at an

1989
01:14:08,480 --> 01:14:14,870
standing by for bachelor separation

1990
01:14:14,880 --> 01:14:21,990
we are in powered flight

1991
01:14:25,910 --> 01:14:23,270
we're an altitude of one kilometer

1992
01:14:25,920 --> 01:14:34,550
standing by

1993
01:14:34,560 --> 01:14:43,510
you remain strong

1994
01:14:43,520 --> 01:15:08,830
touchdown confirmed

1995
01:15:08,840 --> 01:15:53,510
magic you got a thumbnail

1996
01:15:53,520 --> 01:16:19,270
team
