yeah we're working on developing some

41
00:02:06,510 --> 00:02:04,299
new life detection technologies and it

42
00:02:08,160 --> 00:02:06,520
did some field work in Iceland and lots

43
00:02:10,229 --> 00:02:08,170
of lab work so it's been a busy summer

44
00:02:12,000 --> 00:02:10,239

48
00:02:23,069 --> 00:02:21,400
presentation about a month so this was

49
00:02:26,460 --> 00:02:23,079
our opportunity to give them a little

50
00:02:28,229 --> 00:02:26,470
feedback and their fantastic ideas

51
00:02:30,630 --> 00:02:28,239

a special let's play video games episode

55
00:02:38,819 --> 00:02:37,359
but before I let me jump into the rig

56
00:02:39,360 --> 00:02:38,829
roll because if you didn't know this is

57
00:02:42,059 --> 00:02:39,370
NASA's

58
00:02:44,399 --> 00:02:42,069
Valley live a conversational show out of

59
00:02:46,380 --> 00:02:44,409
NASA's Ames Research Center where we

60
00:02:48,750 --> 00:02:46,390
talk to researchers scientists engineers

61
00:02:50,130 --> 00:02:48,760
and all-around cool people about all the

62
00:02:52,289 --> 00:02:50,140
nerdy NASA and news you need to know

63
00:02:55,220 --> 00:02:52,299
about so if you like that I just come to

64
00:02:58,530 --> 00:02:55,230
we are live on YouTube Facebook

65
00:03:00,569 --> 00:02:58,540

00:03:10,259 --> 00:03:08,379
on back behind the scenes is actually

70
00:03:12,119 --> 00:03:10,269
digging through those questions so I

71
00:03:14,190 --> 00:03:12,129
don't have to see the constant deluge of

72
00:03:16,680 --> 00:03:14,200
stuff in the chat but if you can't catch

73
00:03:18,839 --> 00:03:16,690
us live that is no big deal I you kid we

74
00:03:20,099 --> 00:03:18,849
will have video on demand on twitch and

75
00:03:21,809 --> 00:03:20,109
YouTube immediately once the show is

76
00:03:24,330 --> 00:03:21,819
over and the next week it'll be up and

77
00:03:27,569 --> 00:03:24,340
replaying or rebroadcasting over on NASA

78
00:03:29,339 --> 00:03:27,579
TV and also we'll have it on an audio

79
00:03:31,670 --> 00:03:29,349
version for podcast services or

80
00:03:35,220 --> 00:03:31,680
throughout the solar system and beyond

81
00:03:36,869 --> 00:03:35,230
so all right so before we start moving

82
00:03:39,330 --> 00:03:36,879
along folks are in the chat start

83
00:03:40,229 --> 00:03:39,340
sending in those questions now there's

84
00:03:41,729 --> 00:03:40,239
different parts throughout the show

85
00:03:44,370 --> 00:03:41,739
we're just gonna keep jumping in and

86
00:03:46,909 --> 00:03:44,380
grabbing questions from everybody but

87
00:03:50,879 --> 00:03:46,919
you know since we are doing video games

88
00:03:52,199 --> 00:03:50,889
I have to make my art our legal friends

89
00:03:55,890 --> 00:03:52,209
a little bit happy so we're gonna jump

90
00:03:58,259 --> 00:03:55,900
into a fun disclaimer we have a fun

91
00:04:00,839 --> 00:03:58,269
disclaimer over a like under layer I

92
00:04:02,369 --> 00:04:00,849
guess lower third so this is just to

93
00:04:06,690 --> 00:04:02,379
remind everybody as we're playing these

94
00:04:09,119 --> 00:04:06,700
games that NASA does not promote there

95
00:04:10,860 --> 00:04:09,129
we go there it is NASA does not promote

96
00:04:12,659 --> 00:04:10,870
or endorse or will it provide the

97
00:04:14,369 --> 00:04:12,669
appearance of that NASA promotes or

98
00:04:16,289 --> 00:04:14,379
endorses a commercial product service or

99
00:04:18,629 --> 00:04:16,299
activity individuals that playing

100
00:04:21,689 --> 00:04:18,639
specific games does not constitute an

101
00:04:25,050 --> 00:04:21,699
endorsement of such games by NASA or the

102
00:04:26,820 --> 00:04:25,060
US federal government so um yeah then

103
00:04:28,800 --> 00:04:26,830
like with that we're gonna go jump on

104
00:04:30,570 --> 00:04:28,810
into some of our first games but you

105
00:04:32,189 --> 00:04:30,580
know what we did this cool segment

106
00:04:33,659 --> 00:04:32,199
transition so we might as well just play

107
00:04:34,450 --> 00:04:33,669
that on over that we're doing for every

108
00:04:40,550 --> 00:04:34,460
episode

109
00:04:43,559 --> 00:04:40,560
[Music]

110
00:04:45,929 --> 00:04:43,569
of course it's time for a let's play now

111
00:04:48,059 --> 00:04:45,939
this can include controllers 12 sided

112
00:04:50,309 --> 00:04:48,069
dice or a pop o matic bubble but for

113
00:04:52,200 --> 00:04:50,319
this episode we are playing video games

114
00:04:54,779 --> 00:04:52,210
so Scott what do you have for us first

115
00:04:57,929 --> 00:04:54,789
well I came up with a huge list of NASA

116
00:04:59,129 --> 00:04:57,939
related games I thought obviously we're

117
00:05:01,580 --> 00:04:59,139
gonna play a few of these but the first

118
00:05:05,610 --> 00:05:01,590
one that I wanted was elite dangerous

119
00:05:08,070 --> 00:05:05,620
knife which is basically a space sim set

120
00:05:09,540 --> 00:05:08,080
if those and years in the future and not

121
00:05:11,969 --> 00:05:09,550
only can you fly a spaceship but the

122
00:05:13,589 --> 00:05:11,979
game includes renderings of the entire

123
00:05:15,629 --> 00:05:13,599
galaxy so you can go anywhere in the

124
00:05:18,959 --> 00:05:15,639
galaxy including a few places that nASA

125
00:05:21,570 --> 00:05:18,969
has actually sent spacecraft nice so

126
00:05:24,029 --> 00:05:21,580
yeah this is a elite do I think we can't

127
00:05:26,369 --> 00:05:24,039
play it live because yes connection but

128
00:05:29,399 --> 00:05:26,379
we do have highlight reel of some of

129
00:05:32,249 --> 00:05:29,409
exact rare things so what are we looking

130
00:05:35,070 --> 00:05:32,259
at and what are we seeing here we are

131
00:05:37,409 --> 00:05:35,080
flying towards cheran and pluto which

132
00:05:39,510 --> 00:05:37,419
are the two most distance explored

133
00:05:42,510 --> 00:05:39,520
bodies in the solar system and how fast

134
00:05:45,809 --> 00:05:42,520
are we going and it looks like 1.5 times

135
00:05:47,820 --> 00:05:45,819
the speed of light 1,000 years in the

136
00:05:49,409 --> 00:05:47,830
future we'll take some liberties yeah

137
00:05:51,409 --> 00:05:49,419
well I think just slow down a bit so

138
00:05:54,179 --> 00:05:51,419
that we don't fly past them too fast

139
00:05:55,920 --> 00:05:54,189
it's so let's talk a little bit about

140
00:05:57,360 --> 00:05:55,930
that because obviously even being here

141
00:06:00,420 --> 00:05:57,370
over at Ames we're familiar with the new

142
00:06:02,999 --> 00:06:00,430
Horizons spacecraft as if it went

143
00:06:05,550 --> 00:06:03,009
through I mean did the whole flyby of

144
00:06:07,019 --> 00:06:05,560
Pluto got some really cool photos and

145
00:06:10,260 --> 00:06:07,029
now it's heading up to another body you

146
00:06:13,769 --> 00:06:10,270
can remember MU 49 I believe also called

147
00:06:15,389 --> 00:06:13,779
ultimate tool okay and that'll be the

148
00:06:17,939 --> 00:06:15,399
last day of the year when it's doing

149
00:06:19,290 --> 00:06:17,949
that pretty much so you can see we're

150
00:06:21,389 --> 00:06:19,300
coming down there's chair oh and and

151
00:06:23,519 --> 00:06:21,399
Pluto next to each other so the

152
00:06:25,829 --> 00:06:23,529
developers of this game try to

153
00:06:27,209 --> 00:06:25,839
incorporate as much reality as possible

154
00:06:29,369 --> 00:06:27,219
so they took textures from the real

155
00:06:31,589 --> 00:06:29,379
Pluto and Charon and map them onto this

156
00:06:33,119 --> 00:06:31,599
you can't land on Pluto but we will be

157
00:06:35,070 --> 00:06:33,129
able to get closer to a chair oh and I'm

158
00:06:38,070 --> 00:06:35,080
just looking around in the cockpit here

159
00:06:39,689 --> 00:06:38,080
yeah it's of course like you can't talk

160
00:06:41,909 --> 00:06:39,699
about Pluto without the first thing in

161
00:06:44,790 --> 00:06:41,919
chat being like is Pluto a planet that's

162
00:06:46,559 --> 00:06:44,800
tres it's a dwarf planet

163
00:06:48,420 --> 00:06:46,569
there's just a dwarf planet there's

164
00:06:50,309 --> 00:06:48,430
still a planet planet it's the only

165
00:06:52,980 --> 00:06:50,319
binary planet it's a pretty cool plan if

166
00:06:54,570 --> 00:06:52,990
you ask me and and Sharons are really

167
00:06:57,089 --> 00:06:54,580
cool moon like one of the big

168
00:06:59,430 --> 00:06:57,099
discoveries from New Horizons was that

169
00:07:01,860 --> 00:06:59,440
on the North Pole there's a deposit of

170
00:07:03,749 --> 00:07:01,870
these compounds called Dolan's it's like

171
00:07:06,180 --> 00:07:03,759
this kind of reddish material and what

172
00:07:07,950 --> 00:07:06,190
that is is a mixture of organics and and

173
00:07:09,600 --> 00:07:07,960
Pluto doesn't I don't think Pluto has

174
00:07:10,290 --> 00:07:09,610
those deposits but Sharon does which is

175
00:07:11,999 --> 00:07:10,300
pretty neat

176
00:07:16,680 --> 00:07:12,009
now is this Pluto resistor this is

177
00:07:18,089 --> 00:07:16,690
Sharon because yeah and where I wanted

178
00:07:21,059 --> 00:07:18,099
to fly through some of these canyons

179
00:07:22,740 --> 00:07:21,069
that we saw Kozma saw there's seven off

180
00:07:24,390 --> 00:07:22,750
the left that have been named on Sharon

181
00:07:27,360 --> 00:07:24,400
they're all named after fictional

182
00:07:29,430 --> 00:07:27,370
spacecraft dude what I can't remember

183
00:07:31,439 --> 00:07:29,440
which ones never I think they're being

184
00:07:32,779 --> 00:07:31,449
approved by the IAU because they're from

185
00:07:37,200 --> 00:07:32,789
mythology but we've got things like

186
00:07:39,450 --> 00:07:37,210
TARDIS cosmati and Nostromo no serenity

187
00:07:41,580 --> 00:07:39,460
I don't know which one this is I'm

188
00:07:42,869 --> 00:07:41,590
flying through but I am you know trying

189
00:07:46,649 --> 00:07:42,879
to do my best Baker's Canyon

190
00:07:48,570 --> 00:07:46,659
impersonation here nice nice I'm really

191
00:07:50,580 --> 00:07:48,580
digging the cockpit here this is this

192
00:07:53,189 --> 00:07:50,590
it's so much better in VR when you can

193
00:07:55,020 --> 00:07:53,199
look around and see everything this is

194
00:07:57,540 --> 00:07:55,030
one of the best things to have in VR

195
00:08:00,480 --> 00:07:57,550
this I was going to say for Chad as our

196
00:08:01,890 --> 00:08:00,490
as our director of engineering or acting

197
00:08:03,779 --> 00:08:01,900
director of engineering here at Ames

198
00:08:06,870 --> 00:08:03,789
like what would you give for a cockpit

199
00:08:09,659 --> 00:08:06,880
like this a lot a lot yeah this this is

200
00:08:11,129 --> 00:08:09,669
um it's easy to forget that it's

201
00:08:12,709 --> 00:08:11,139
supposedly a thousand years in the

202
00:08:15,059 --> 00:08:12,719
future right because a lot of the

203
00:08:17,640 --> 00:08:15,069
concepts and ideas that we've been

204
00:08:21,930 --> 00:08:17,650
working on sort of play into that same

205
00:08:23,249 --> 00:08:21,940
general look and feel and yet you know

206
00:08:24,870 --> 00:08:23,259
if you do it right maybe that's what

207
00:08:27,420 --> 00:08:24,880
they'll use a thousand thousand years

208
00:08:29,040 --> 00:08:27,430
hence but I love the you know he's got a

209
00:08:30,330 --> 00:08:29,050
little map whether the solar system down

210
00:08:33,180 --> 00:08:30,340
there tells you where we are and how to

211
00:08:35,050 --> 00:08:33,190
navigate there's some terrain shows up

212
00:08:37,240 --> 00:08:35,060
in there

213
00:08:39,670 --> 00:08:37,250
this is the first time I've ever seen

214
00:08:41,320 --> 00:08:39,680
this particular game it's just it's kind

215
00:08:43,149 --> 00:08:41,330
of interesting to find your way around

216
00:08:45,010 --> 00:08:43,159
in there visually and see what's going

217
00:08:47,290 --> 00:08:45,020
on in the game there's something that

218
00:08:49,000 --> 00:08:47,300
you might remember from the past year

219
00:08:53,650 --> 00:08:49,010
we're actually coming up to an ancient

220
00:08:54,850 --> 00:08:53,660
space probe the ancients possible and if

221
00:08:55,510 --> 00:08:54,860
you I don't know if you can hear the

222
00:08:59,560 --> 00:08:55,520
audio

223
00:09:04,110 --> 00:08:59,570
for the audience so that they can hear

224
00:09:10,120 --> 00:09:08,410
yeah listen to that as you me well cuz

225
00:09:11,500 --> 00:09:10,130
right now where is Voyager right now cuz

226
00:09:13,329 --> 00:09:11,510
this isn't where Voyager is right now

227
00:09:14,620 --> 00:09:13,339
right now this is where Voyager will be

228
00:09:16,570 --> 00:09:14,630
in thousand years in the future right

229
00:09:18,280 --> 00:09:16,580
yeah this is like I don't know how far

230
00:09:19,900 --> 00:09:18,290
out it is like it's alright it's left

231
00:09:21,700 --> 00:09:19,910
the solar system technically has crossed

232
00:09:24,220 --> 00:09:21,710
the heliopause into interstellar space

233
00:09:27,610 --> 00:09:24,230
it's the only man-made object ever to do

234
00:09:28,960 --> 00:09:27,620
so yeah but I brought along an

235
00:09:30,550 --> 00:09:28,970
interesting problem I don't know if we

236
00:09:34,630 --> 00:09:30,560
can I know we can do the picture in

237
00:09:37,660 --> 00:09:34,640
pictures we have printer repressing off

238
00:09:39,340 --> 00:09:37,670
the Voyager Golden Record this was done

239
00:09:43,060 --> 00:09:39,350
last year and then the insight they have

240
00:09:45,340 --> 00:09:43,070
all the they have all the music and the

241
00:09:47,620 --> 00:09:45,350
sounds the greetings from the various

242
00:09:51,000 --> 00:09:47,630
parts of the world and my favorite part

243
00:09:53,740 --> 00:09:51,010
being a DJ is a slip mat showing the

244
00:09:59,650 --> 00:09:53,750
trajectory that Voyager took on the way

245
00:10:01,360 --> 00:09:59,660
and the two voyagers took so yes gravity

246
00:10:06,490 --> 00:10:01,370
assists we've been past different

247
00:10:07,690 --> 00:10:06,500
yeah three assists for tooted but we

248
00:10:09,880 --> 00:10:07,700
should talk about like what it was it

249
00:10:11,590 --> 00:10:09,890
was a record that was put together to

250
00:10:14,230 --> 00:10:11,600
represent all of the sounds of the earth

251
00:10:16,390 --> 00:10:14,240
and the very first part of the record is

252
00:10:19,180 --> 00:10:16,400
recordings of I think like over 50

253
00:10:21,280 --> 00:10:19,190
languages greetings and then it goes

254
00:10:23,440 --> 00:10:21,290
into like the you know the best the best

255
00:10:25,420 --> 00:10:23,450
music from all over the globe was

256
00:10:27,550 --> 00:10:25,430
compiled and and put on to this record

257
00:10:32,230 --> 00:10:27,560
and affixed on to the front of the

258
00:10:34,600 --> 00:10:32,240
spacecraft and in about let's see tens

259
00:10:36,610 --> 00:10:34,610
to hundreds of thousands of years this

260
00:10:39,310 --> 00:10:36,620
uh the voyagers will pass by nearby

261
00:10:41,199 --> 00:10:39,320
stars so the idea is someday maybe

262
00:10:42,730 --> 00:10:41,209
somebody will find it and be able to

263
00:10:43,220 --> 00:10:42,740
listen to the sounds of Earth well it

264
00:10:47,630 --> 00:10:43,230
was

265
00:10:50,000 --> 00:10:47,640
right on the surface of the record

266
00:10:52,370 --> 00:10:50,010
it tells whoever might find the record

267
00:10:54,170 --> 00:10:52,380
basically what a record is and how to

268
00:10:56,570 --> 00:10:54,180
get to inflation back off of it right

269
00:10:58,550 --> 00:10:56,580
says like there's there's sound waves on

270
00:11:00,860 --> 00:10:58,560
here and this is what they look like and

271
00:11:03,440 --> 00:11:00,870
here's here's what you need to do to

272
00:11:05,690 --> 00:11:03,450
play the thing back you know plus other

273
00:11:07,400 --> 00:11:05,700
basic information content but you know

274
00:11:08,930 --> 00:11:07,410
starting with hey here's what this

275
00:11:11,240 --> 00:11:08,940
artifact is and what you might do with

276
00:11:13,280 --> 00:11:11,250
it to get at the information contained

277
00:11:14,690 --> 00:11:13,290
good summation so Before we jump over

278
00:11:16,970 --> 00:11:14,700
the next one somebody named silent

279
00:11:18,620 --> 00:11:16,980
searchlights at NASA have either of the

280
00:11:22,780 --> 00:11:18,630
Voyager probes traveled beyond the

281
00:11:25,790 --> 00:11:22,790
outermost radius of the Oort cloud yet

282
00:11:27,410 --> 00:11:25,800
no they aren't quite we for the road it

283
00:11:30,380 --> 00:11:27,420
goes out to a hundred thousand au or

284
00:11:33,980 --> 00:11:30,390
beyond so there you go silent

285
00:11:37,130 --> 00:11:33,990
searchlight i know silence or smudges on

286
00:11:38,270 --> 00:11:37,140
their way but it'll take a long time for

287
00:11:41,210 --> 00:11:38,280
them to get out that far

288
00:11:44,210 --> 00:11:41,220
and so okay so what are we looking at

289
00:11:46,370 --> 00:11:44,220
coming up over here we are yeah we've

290
00:11:48,890 --> 00:11:46,380
just continuing on our journey we flew

291
00:11:50,840 --> 00:11:48,900
past the sun past mule parkour solar

292
00:11:53,240 --> 00:11:50,850
pool but we're gonna go to the moon and

293
00:11:55,250 --> 00:11:53,250
i know NASA is talking about a space

294
00:11:56,900 --> 00:11:55,260
station around the moon well we have a

295
00:11:58,280 --> 00:11:56,910
space station around the moon a thousand

296
00:12:01,160 --> 00:11:58,290
years in the future in this fictional

297
00:12:03,530 --> 00:12:01,170
universe it's a little bit bigger than

298
00:12:06,290 --> 00:12:03,540
what nASA has in mind okay

299
00:12:08,120 --> 00:12:06,300
this is called Galileo but I just wanted

300
00:12:10,220 --> 00:12:08,130
to show the docking sequence in this

301
00:12:12,470 --> 00:12:10,230
game because it's pretty cool it is

302
00:12:16,410 --> 00:12:12,480
pretty cool obviously takes some

303
00:12:19,530 --> 00:12:16,420
inspiration from 2001 year

304
00:12:22,170 --> 00:12:19,540
this is the Galileo spacecraft Ussuri no

305
00:12:24,509 --> 00:12:22,180
spacecraft Space Station and you need to

306
00:12:27,509 --> 00:12:24,519
request docking permission from the

307
00:12:30,750 --> 00:12:27,519
space traffic control it's a future

308
00:12:33,210 --> 00:12:30,760
where they don't have magical artificial

309
00:12:34,949 --> 00:12:33,220
gravity soul for most people to get

310
00:12:36,000 --> 00:12:34,959
gravity they have to rotate the station

311
00:12:39,420 --> 00:12:36,010
which means you have to match the

312
00:12:40,920 --> 00:12:39,430
rotation the very realistic it's

313
00:12:43,199 --> 00:12:40,930
realistic in that way but this of course

314
00:12:45,269 --> 00:12:43,209
there and there's already like like

315
00:12:47,579 --> 00:12:45,279
billboards and space advertising NASA is

316
00:12:50,819 --> 00:12:47,589
not endorse any of those no that's not

317
00:12:54,000 --> 00:12:50,829
endorse or appear to promote or endorse

318
00:12:55,769 --> 00:12:54,010
any of the space advertising Titan City

319
00:12:59,850 --> 00:12:55,779
yeah there's a tiny City you can go

320
00:13:01,800 --> 00:12:59,860
there if you like it's another space

321
00:13:04,170 --> 00:13:01,810
station in orbit around Titan but

322
00:13:05,670 --> 00:13:04,180
there's probably 50 s on the surface of

323
00:13:07,500 --> 00:13:05,680
Titan but you can't land there right now

324
00:13:09,569 --> 00:13:07,510
because the game only lets you land on

325
00:13:12,180 --> 00:13:09,579
planets with no atmosphere which is a

326
00:13:14,699 --> 00:13:12,190
shame because Titan is a fantastic place

327
00:13:15,960 --> 00:13:14,709
to visit with lots of atmosphere I think

328
00:13:18,420 --> 00:13:15,970
it's the only other place in the solar

329
00:13:20,400 --> 00:13:18,430
system where it actually rains really

330
00:13:22,740 --> 00:13:20,410
yeah it rains liquid ethane and methane

331
00:13:24,569 --> 00:13:22,750
though yeah at least with a solid

332
00:13:27,420 --> 00:13:24,579
surface I think there's possibility of

333
00:13:29,340 --> 00:13:27,430
rains in some of the gas giants yeah my

334
00:13:31,470 --> 00:13:29,350
experience with Titan has been playing

335
00:13:33,090 --> 00:13:31,480
in destiny too they have Titan and they

336
00:13:34,740 --> 00:13:33,100
have these like oceans this basically

337
00:13:36,150 --> 00:13:34,750
went from a frozen planet to ocean

338
00:13:37,829 --> 00:13:36,160
worlds and the only time I'm sitting

339
00:13:39,540 --> 00:13:37,839
there they have like somebody who you

340
00:13:40,680 --> 00:13:39,550
talk to and they have their helmet off

341
00:13:45,900 --> 00:13:40,690
and they're just like chatting with you

342
00:13:48,569 --> 00:13:45,910
and I'm like pretty cool Kelvin it's

343
00:13:50,790 --> 00:13:48,579
like even if it's like okay so the

344
00:13:52,350 --> 00:13:50,800
methane isn't frozen but it's liquid

345
00:13:54,960 --> 00:13:52,360
oceans of methane it's still gonna be

346
00:13:56,699 --> 00:13:54,970
pretty cold outside pretty cool so

347
00:14:00,389 --> 00:13:56,709
anyway yeah I guess a next point after

348
00:14:03,809 --> 00:14:00,399
stopping to get some coffee time to head

349
00:14:05,430 --> 00:14:03,819
out into the outer solar system taking a

350
00:14:06,870 --> 00:14:05,440
look around as well yeah people love

351
00:14:09,600 --> 00:14:06,880
their greenhouses there's other

352
00:14:12,059 --> 00:14:09,610
spaceships obviously I'm gonna point out

353
00:14:13,530 --> 00:14:12,069
that while this game does let you shoot

354
00:14:15,540 --> 00:14:13,540
other people and it's a big part of the

355
00:14:18,059 --> 00:14:15,550
game during the sequence I decided to be

356
00:14:21,000 --> 00:14:18,069
totally a pacifist I don't even have

357
00:14:22,560 --> 00:14:21,010
guns in my spaceship no nice now and

358
00:14:25,500 --> 00:14:22,570
there are aliens

359
00:14:27,810 --> 00:14:25,510
yeah well looking through the chat a lot

360
00:14:30,360 --> 00:14:27,820
of shoutouts to Scott hello

361
00:14:33,200 --> 00:14:30,370
so hello everybody and then there was

362
00:14:36,060 --> 00:14:33,210
another person news I think it's a cap

363
00:14:38,730 --> 00:14:36,070
captain - aye aye is asking what time

364
00:14:40,440 --> 00:14:38,740
line is this said what about thousand a

365
00:14:43,380 --> 00:14:40,450
thousand years in the future and they

366
00:14:44,370 --> 00:14:43,390
has real-time advances in March with our

367
00:14:47,030 --> 00:14:44,380
own time

368
00:14:51,660 --> 00:14:47,040
so it's you know September 27th in

369
00:14:53,430 --> 00:14:51,670
whatever year it is somebody as an

370
00:14:54,360 --> 00:14:53,440
engineer like talk a little bit about

371
00:14:56,130 --> 00:14:54,370
like what are some of those

372
00:14:58,440 --> 00:14:56,140
complications to actually build these

373
00:15:00,210 --> 00:14:58,450
things I mean we're way far off but it's

374
00:15:02,250 --> 00:15:00,220
like there's a lot of stuff we have to

375
00:15:02,460 --> 00:15:02,260
figure out before anything even comes

376
00:15:04,620 --> 00:15:02,470
close

377
00:15:06,360 --> 00:15:04,630
absolutely right and some some of it

378
00:15:08,430 --> 00:15:06,370
we're starting to work on and figure out

379
00:15:10,770 --> 00:15:08,440
one of the big questions is if you want

380
00:15:13,410 --> 00:15:10,780
to build something really big in space

381
00:15:15,000 --> 00:15:13,420
yeah just how do you do that well the

382
00:15:16,710 --> 00:15:15,010
biggest thing we've ever built in space

383
00:15:20,070 --> 00:15:16,720
is the International Space Station and

384
00:15:22,170 --> 00:15:20,080
by and large we built that by sending

385
00:15:25,770 --> 00:15:22,180
all the pieces up as modules and

386
00:15:27,870 --> 00:15:25,780
assembling them on orbit with a lot of

387
00:15:31,230 --> 00:15:27,880
human labor I was mostly astronauts

388
00:15:32,580 --> 00:15:31,240
putting things together in space and you

389
00:15:35,070 --> 00:15:32,590
could do it that way but if you're

390
00:15:36,690 --> 00:15:35,080
talking a you know Space Station the

391
00:15:39,630 --> 00:15:36,700
size of this it's good if you know

392
00:15:42,480 --> 00:15:39,640
there's a huge human labor problem or

393
00:15:44,160 --> 00:15:42,490
alien labor as the case may be and so

394
00:15:45,690 --> 00:15:44,170
we've really been putting a lot of

395
00:15:48,900 --> 00:15:45,700
effort into figuring out how do you do

396
00:15:50,700 --> 00:15:48,910
this robotically yeah so that you can

397
00:15:52,350 --> 00:15:50,710
have the robots go do it you said no

398
00:15:54,120 --> 00:15:52,360
BOTS can deal with the cold wet send up

399
00:15:56,700 --> 00:15:54,130
the raw material let the robots put it

400
00:15:58,620 --> 00:15:56,710
all together will show up and live take

401
00:15:59,640 --> 00:15:58,630
take advantage of that well that's it

402
00:16:00,990 --> 00:15:59,650
one of the cool things we've talked a

403
00:16:02,340 --> 00:16:01,000
lot about like on the journey to Mars

404
00:16:03,810 --> 00:16:02,350
I've talked about going to Mars and talk

405
00:16:05,430 --> 00:16:03,820
about in the moon I was like there's a

406
00:16:06,870 --> 00:16:05,440
lot of stuff about like humans living in

407
00:16:08,550 --> 00:16:06,880
deep space that we still have to figure

408
00:16:10,320 --> 00:16:08,560
out and like a cool thing about being at

409
00:16:13,370 --> 00:16:10,330
the moon is like if something goes wrong

410
00:16:15,480 --> 00:16:13,380
you know you're not two years away

411
00:16:17,970 --> 00:16:15,490
you know you could try to get back a

412
00:16:20,070 --> 00:16:17,980
little bit sooner if you're far if

413
00:16:21,600 --> 00:16:20,080
you're far away right even as far as the

414
00:16:24,120 --> 00:16:21,610
moon you have to take a lot of those

415
00:16:25,350 --> 00:16:24,130
things that we take for granted here on

416
00:16:28,890 --> 00:16:25,360
earth you have to take them with you

417
00:16:32,400 --> 00:16:28,900
right whether it's raw material

418
00:16:34,410 --> 00:16:32,410
resources whether it's consumables you

419
00:16:37,020 --> 00:16:34,420
know whether it's water oxygen

420
00:16:39,150 --> 00:16:37,030
food all of those things that we just

421
00:16:42,180 --> 00:16:39,160
sort of you know hey I have my cup mug

422
00:16:44,970 --> 00:16:42,190
of water right here if I'm out there in

423
00:16:46,740 --> 00:16:44,980
a space station it's not readily

424
00:16:49,200 --> 00:16:46,750
accessible as a natural resource

425
00:16:52,050 --> 00:16:49,210
it's either stuff I took with me or

426
00:16:54,390 --> 00:16:52,060
stuff I'm making out of materials I took

427
00:16:58,380 --> 00:16:54,400
with me that's kind of a closed system

428
00:17:00,630 --> 00:16:58,390
yeah and that really puts puts a whole

429
00:17:02,430 --> 00:17:00,640
new load on the technology on how we do

430
00:17:04,890 --> 00:17:02,440
it and we're having to figure those

431
00:17:06,780 --> 00:17:04,900
things out all the time whether it's on

432
00:17:10,140 --> 00:17:06,790
your International Space Station or the

433
00:17:12,480 --> 00:17:10,150
new lunar gateway or you know anything

434
00:17:14,069 --> 00:17:12,490
we want to go do you have to figure out

435
00:17:16,439 --> 00:17:14,079
how to do it with the materials you've

436
00:17:20,250 --> 00:17:16,449
got that you took with you so going on

437
00:17:22,560 --> 00:17:20,260
in the in the background is we just buzz

438
00:17:25,290 --> 00:17:22,570
we passed we flew through this Saturn

439
00:17:27,920 --> 00:17:25,300
system just like Cassini but we spent a

440
00:17:32,880 --> 00:17:27,930
little less time there than Cassini yes

441
00:17:36,260 --> 00:17:32,890
yes because he's still there like in

442
00:17:39,210 --> 00:17:36,270
many pieces burnt up like it's at least

443
00:17:41,520 --> 00:17:39,220
present I'm Saturn I'm sure and Huygens

444
00:17:43,470 --> 00:17:41,530
are still intact so you know so you have

445
00:17:45,930 --> 00:17:43,480
another landing base over here yeah cuz

446
00:17:48,000 --> 00:17:45,940
I wanted to get another spaceship with a

447
00:17:50,880 --> 00:17:48,010
little rule earth I can actually go and

448
00:17:53,790 --> 00:17:50,890
visit the surface we flew past Enceladus

449
00:17:57,210 --> 00:17:53,800
okay Enceladus Enceladus which is a moon

450
00:17:58,920 --> 00:17:57,220
of Titan Saturn's honey Hey what is the

451
00:18:00,840 --> 00:17:58,930
proper what we have we were just talking

452
00:18:02,580 --> 00:18:00,850
about it of like is it Enceladus and

453
00:18:04,260 --> 00:18:02,590
saladin so how do I heard it pronounced

454
00:18:06,130 --> 00:18:04,270
Enceladus but I've heard it also

455
00:18:07,720 --> 00:18:06,140
pronounced the other way too just

456
00:18:11,560 --> 00:18:07,730
tens on how you feel how your fancy

457
00:18:13,600 --> 00:18:11,570
cancelados nice we had the same

458
00:18:16,660 --> 00:18:13,610
conversation around like Sharon is it

459
00:18:20,380 --> 00:18:16,670
Sharon okay I actually looked it up the

460
00:18:22,690 --> 00:18:20,390
moon Charon it was named in part after

461
00:18:27,910 --> 00:18:22,700
the discoverers wife whose name was

462
00:18:31,090 --> 00:18:27,920
Charlene so like I guess the community

463
00:18:34,420 --> 00:18:31,100
pronounces it Sharon after Charlene but

464
00:18:37,360 --> 00:18:34,430
it's officially named after a you know a

465
00:18:38,980 --> 00:18:37,370
mythological figure so and and the

466
00:18:42,040 --> 00:18:38,990
correct way to pronounce it in that case

467
00:18:42,970 --> 00:18:42,050
is Karen but in in a scientific

468
00:18:45,130 --> 00:18:42,980
conference you're not going to hear that

469
00:18:47,380 --> 00:18:45,140
pronunciation who was I guess that

470
00:18:51,630 --> 00:18:47,390
particular mythological figure was like

471
00:18:55,000 --> 00:18:51,640
the because Pluto was named after the

472
00:18:56,680 --> 00:18:55,010
Lord of the underworld but Karen like

473
00:18:58,690 --> 00:18:56,690
was the ferryman that took people across

474
00:19:01,060 --> 00:18:58,700
the river so it was like the river state

475
00:19:12,070 --> 00:19:01,070
yeah yes it's not the Disney character

476
00:19:13,690 --> 00:19:12,080
know which five through Europa recently

477
00:19:17,380 --> 00:19:13,700
they found ice geysers they're using

478
00:19:18,850 --> 00:19:17,390
data from Galileo and Voyager right huh

479
00:19:21,460 --> 00:19:18,860
we found that there's actually

480
00:19:24,220 --> 00:19:21,470
cryovolcanism and there's Europe is

481
00:19:25,780 --> 00:19:24,230
obviously fascinating from astrobiology

482
00:19:28,990 --> 00:19:25,790
standpoint because it's got this huge

483
00:19:31,300 --> 00:19:29,000
ocean right yeah there's just beneath

484
00:19:31,780 --> 00:19:31,310
the surface is there's a thick sheet of

485
00:19:33,310 --> 00:19:31,790
ice

486
00:19:35,830 --> 00:19:33,320
a few kilometers and then beneath that

487
00:19:37,300 --> 00:19:35,840
is there's a lot of water I know I know

488
00:19:39,490 --> 00:19:37,310
that Mary Beth can literally talk all

489
00:19:41,650 --> 00:19:39,500
day about your biology drop for at least

490
00:19:46,330 --> 00:19:41,660
a few hours and visitation that you just

491
00:19:48,040 --> 00:19:46,340
do but yeah it's kind of hard to imagine

492
00:19:50,170 --> 00:19:48,050
an ocean world like this because like

493
00:19:52,090 --> 00:19:50,180
it's completely dark so when we think of

494
00:19:53,740 --> 00:19:52,100
our Earth's oceans like we imagine light

495
00:19:56,080 --> 00:19:53,750
streaming and in like beautiful green

496
00:19:58,150 --> 00:19:56,090
algae but like if life exists on Europa

497
00:19:59,740 --> 00:19:58,160
its it's living off of chemical energy

498
00:20:02,770 --> 00:19:59,750
and complete darkness so it's like a

499
00:20:05,950 --> 00:20:02,780
totally alien way to think about living

500
00:20:08,650 --> 00:20:05,960
miss an event says you guys ought to go

501
00:20:09,400 --> 00:20:08,660
to the geysers on Europa I think we got

502
00:20:11,230 --> 00:20:09,410
you one better

503
00:20:12,289 --> 00:20:11,240
right alright we are we are at the

504
00:20:14,329 --> 00:20:12,299
geysers on

505
00:20:16,159 --> 00:20:14,339
is it Europa or is it the Enceladus well

506
00:20:18,769 --> 00:20:16,169
this is Europe by way oh there you go

507
00:20:21,049 --> 00:20:18,779
this is a relatively new discovery yes

508
00:20:22,969 --> 00:20:21,059
but it's based on old data yeah which is

509
00:20:26,629 --> 00:20:22,979
always fascinating to find new

510
00:20:28,399 --> 00:20:26,639
discoveries in old data so yeah this is

511
00:20:30,529 --> 00:20:28,409
an ASP Explorer much better code but you

512
00:20:32,479 --> 00:20:30,539
can see a lot more there so we just

513
00:20:35,599 --> 00:20:32,489
spell that's horse for a beauty or show

514
00:20:37,369 --> 00:20:35,609
nice is the Vista shot that's right

515
00:20:43,519 --> 00:20:37,379
that's Jupiter in the background there's

516
00:20:45,289 --> 00:20:43,529
free samples actually yeah I'm gonna get

517
00:20:47,749 --> 00:20:45,299
it in my Rover and go for a drive yeah

518
00:20:50,869 --> 00:20:47,759
all right so let's check this out yeah I

519
00:20:54,709 --> 00:20:50,879
mean the game has had you know volcanic

520
00:20:57,079 --> 00:20:54,719
fumaroles weird alien fungi alien

521
00:20:58,909 --> 00:20:57,089
archaeology they're all things you can

522
00:21:02,539 --> 00:20:58,919
visit but we're staying within the

523
00:21:04,399 --> 00:21:02,549
realms of reality at this point although

524
00:21:06,049 --> 00:21:04,409
these geysers are a little more powerful

525
00:21:09,859 --> 00:21:06,059
than the ones in real life I suspect

526
00:21:11,629 --> 00:21:09,869
really isn't so in fact with when the

527
00:21:12,799 --> 00:21:11,639
recent discoveries of I mean cool thing

528
00:21:15,469 --> 00:21:12,809
about these geysers the idea is like

529
00:21:19,249 --> 00:21:15,479
they found like was it like like the

530
00:21:21,169 --> 00:21:19,259
building blocks of life on Enceladus on

531
00:21:23,539 --> 00:21:21,179
Enceladus also has a geyser which is

532
00:21:26,690 --> 00:21:23,549
which I think they're much larger yeah

533
00:21:28,999 --> 00:21:26,700
yeah that means like astrobiology for

534
00:21:31,190 --> 00:21:29,009
you know future NASA missions we're

535
00:21:33,169 --> 00:21:31,200
hoping to do I mean like imagine like

536
00:21:34,849 --> 00:21:33,179
how much easier it is just to fly

537
00:21:37,459 --> 00:21:34,859
through a plume and take a sample rather

538
00:21:38,869 --> 00:21:37,469
than have to land and drive around and

539
00:21:40,489 --> 00:21:38,879
collect sample us we're doing in this or

540
00:21:42,680 --> 00:21:40,499
drill through many kilometers of ice

541
00:21:44,959 --> 00:21:42,690
yeah I mean like that's really hard to

542
00:21:46,310 --> 00:21:44,969
do on earth let alone on you know

543
00:21:49,039 --> 00:21:46,320
something that's that far away from

544
00:21:50,119 --> 00:21:49,049
Earth but yeah the the samples

545
00:21:51,680 --> 00:21:50,129
themselves are really interesting

546
00:21:53,659 --> 00:21:51,690
because they've identified all of the

547
00:21:56,989 --> 00:21:53,669
raw ingredients needed for life in those

548
00:21:58,819 --> 00:21:56,999
plumes so the hope is that you know we

549
00:22:00,979 --> 00:21:58,829
could send a more advanced type of

550
00:22:03,799 --> 00:22:00,989
instrument that could actually tell us

551
00:22:05,659 --> 00:22:03,809
if there is life contained within that

552
00:22:07,699 --> 00:22:05,669
sample and I think that's gonna be one

553
00:22:09,739 --> 00:22:07,709
of the most exciting missions you know

554
00:22:11,659 --> 00:22:09,749
in my lifetime certainly you know trying

555
00:22:13,190 --> 00:22:11,669
to answer this question of you know is

556
00:22:13,849 --> 00:22:13,200
there microbial life anywhere else in

557
00:22:16,969 --> 00:22:13,859
the solar system

558
00:22:19,039 --> 00:22:16,979
I remember the material coming up out of

559
00:22:21,919 --> 00:22:19,049
those plumes is the material from down

560
00:22:24,190 --> 00:22:21,929
below that ice layer and so we think if

561
00:22:27,090 --> 00:22:24,200
if there's life to be found it's down

562
00:22:29,169 --> 00:22:27,100
that comparatively warm environment and

563
00:22:30,759 --> 00:22:29,179
rather than having to drill down through

564
00:22:32,289 --> 00:22:30,769
the ice to get to it hey it's

565
00:22:34,210 --> 00:22:32,299
conveniently coming right up

566
00:22:36,460 --> 00:22:34,220
yeah head up through the form of a these

567
00:22:38,289 --> 00:22:36,470
guys are using these vents and so we can

568
00:22:39,789 --> 00:22:38,299
we don't even have to land on the

569
00:22:41,830 --> 00:22:39,799
surface to collect those samples we

570
00:22:44,080 --> 00:22:41,840
could just fly through them from above

571
00:22:46,330 --> 00:22:44,090
and so like one of the things I get a

572
00:22:47,889 --> 00:22:46,340
kick out of this game especially is like

573
00:22:49,600 --> 00:22:47,899
the data that it uses it's like it's

574
00:22:52,060 --> 00:22:49,610
using real damn it's really seasoned

575
00:22:54,970 --> 00:22:52,070
yeah this is the shots that we just had

576
00:22:57,250 --> 00:22:54,980
that we can have yeah bill if you want

577
00:23:00,700 --> 00:22:57,260
to jump on back a little bit to that big

578
00:23:04,090 --> 00:23:00,710
shot of all the stars yeah like so this

579
00:23:05,830 --> 00:23:04,100
is real data taken from these stars or

580
00:23:08,259 --> 00:23:05,840
real stars I mean they start to fill in

581
00:23:09,370 --> 00:23:08,269
once they get to farther right but many

582
00:23:11,560 --> 00:23:09,380
of these are some of these have been

583
00:23:14,409 --> 00:23:11,570
identified by NASA missions such as wise

584
00:23:17,590 --> 00:23:14,419
850 507 1:4 right that was the

585
00:23:19,600 --> 00:23:17,600
wide-field Infrared Survey Explorer so

586
00:23:21,970 --> 00:23:19,610
they've obviously measured the colors

587
00:23:24,220 --> 00:23:21,980
and parallaxes and put these planets in

588
00:23:27,190 --> 00:23:24,230
place but they try to extend this out to

589
00:23:28,600 --> 00:23:27,200
the entire galaxy and you can go a long

590
00:23:30,279 --> 00:23:28,610
way out you can travel to the core of

591
00:23:32,379 --> 00:23:30,289
the galaxy if you like and get to

592
00:23:34,899 --> 00:23:32,389
Sagittarius a star the supermassive

593
00:23:37,029 --> 00:23:34,909
black hole in the middle you see we've

594
00:23:39,879 --> 00:23:37,039
got nebula to California nebula

595
00:23:42,279 --> 00:23:39,889
Barnard's loop Polaris obviously pretty

596
00:23:45,159 --> 00:23:42,289
well known star so I'm really curious if

597
00:23:47,560 --> 00:23:45,169
any of exoplanets that have been

598
00:23:50,440 --> 00:23:47,570
discovered by our Kepler mission have

599
00:23:53,009 --> 00:23:50,450
found their way into the orbits around

600
00:23:55,600 --> 00:23:53,019
these stars funny you should say that

601
00:23:57,909 --> 00:23:55,610
because we haven't able to travel

602
00:24:00,090 --> 00:23:57,919
anywhere on the galaxy and I might just

603
00:24:02,769 --> 00:24:00,100
pay a visit to one of those Kepler's

604
00:24:04,629 --> 00:24:02,779
though that's where we're going next

605
00:24:07,750 --> 00:24:04,639
we've been traveling around it's not

606
00:24:09,310 --> 00:24:07,760
plan that yeah so we'd be traveling

607
00:24:11,320 --> 00:24:09,320
around at the speed of light but using

608
00:24:14,470 --> 00:24:11,330
hyperspace we can travel even faster

609
00:24:16,389 --> 00:24:14,480
nice it's a you can travel up to 2,000

610
00:24:18,009 --> 00:24:16,399
times it's B delay or we can cross 50

611
00:24:19,840 --> 00:24:18,019
light-years in a matter of seconds

612
00:24:21,820 --> 00:24:19,850
because it's a game you don't want

613
00:24:23,470 --> 00:24:21,830
people kick around forever yeah that's

614
00:24:27,750 --> 00:24:23,480
not a fun time so we're heading to

615
00:24:30,690 --> 00:24:27,760
Kepler 42 which was one of the Kepler

616
00:24:33,000 --> 00:24:30,700
points postponed was obvious in the

617
00:24:36,900 --> 00:24:33,010
field of view and the phones planets

618
00:24:39,090 --> 00:24:36,910
transiting several large hot Jupiters

619
00:24:40,920 --> 00:24:39,100
very close to this parent star I

620
00:24:44,250 --> 00:24:40,930
remember I'm talking to one of the NASA

621
00:24:45,990 --> 00:24:44,260
Kepler project scientists the way she

622
00:24:49,200 --> 00:24:46,000
described it's like you put your hand up

623
00:24:50,850 --> 00:24:49,210
into the air and what your hand covers

624
00:24:52,830 --> 00:24:50,860
is basically the field of view of what

625
00:24:55,530 --> 00:24:52,840
Kepler was looking at and all of the

626
00:24:57,090 --> 00:24:55,540
planets that it confirm of exoplanets

627
00:24:58,740 --> 00:24:57,100
are confirmed in just that little itty

628
00:25:00,990 --> 00:24:58,750
bitty space and Tess is even doing so

629
00:25:02,490 --> 00:25:01,000
much more than that yeah the Kepler kept

630
00:25:05,760 --> 00:25:02,500
it all pointing at the same place for

631
00:25:07,230 --> 00:25:05,770
months weeks years even this tas is

632
00:25:09,000 --> 00:25:07,240
spending a little less time so those are

633
00:25:11,790 --> 00:25:09,010
the three hot Jupiters so those are

634
00:25:13,860 --> 00:25:11,800
based on the real the data has been

635
00:25:16,980 --> 00:25:13,870
returned this of course does cause

636
00:25:18,840 --> 00:25:16,990
problems for the game because yeah the

637
00:25:21,020 --> 00:25:18,850
recent you know a new data said that

638
00:25:23,310 --> 00:25:21,030
gets a guy emission yes they have

639
00:25:25,080 --> 00:25:23,320
changed many of the positions of the

640
00:25:27,390 --> 00:25:25,090
stars the distances into the game is

641
00:25:32,580 --> 00:25:27,400
hasn't decided to update its release

642
00:25:34,770 --> 00:25:32,590
universe but it did add it added

643
00:25:37,610 --> 00:25:34,780
Trappist best practices oh nice yeah

644
00:25:40,920 --> 00:25:37,620
which is the closest star it's not

645
00:25:42,900 --> 00:25:40,930
Proxima okay has a pose the most but

646
00:25:45,300 --> 00:25:42,910
it's only like 4 light years is pretty

647
00:25:48,120 --> 00:25:45,310
cool spine has a lot yeah and a lot of

648
00:25:50,990 --> 00:25:48,130
exoplanet yes but the exciting thing is

649
00:25:54,810 --> 00:25:51,000
now from the results of Kepler in k2 it

650
00:25:58,470 --> 00:25:54,820
amazingly right pretty much every star

651
00:25:59,700 --> 00:25:58,480
on average has at least one planet and

652
00:26:00,720 --> 00:25:59,710
there's some stars that don't have any

653
00:26:02,970 --> 00:26:00,730
there's some stars that have a lot more

654
00:26:04,740 --> 00:26:02,980
but on average there's at least a planet

655
00:26:06,030 --> 00:26:04,750
for every star that's out there and so

656
00:26:09,060 --> 00:26:06,040
you think about the billions and

657
00:26:10,800 --> 00:26:09,070
billions of stars that's billions and

658
00:26:13,230 --> 00:26:10,810
billions of planets and even if it's a

659
00:26:15,630 --> 00:26:13,240
small fraction of them that is anything

660
00:26:18,390 --> 00:26:15,640
remotely like Earth that's still a huge

661
00:26:19,590 --> 00:26:18,400
huge number it's just exciting this is

662
00:26:21,450 --> 00:26:19,600
the part where Kavon and the chat is

663
00:26:27,000 --> 00:26:21,460
gonna put the hash tag more planets than

664
00:26:29,460 --> 00:26:27,010
stars so that's a pretty wild paradigm

665
00:26:31,000 --> 00:26:29,470
shift I mean like you know growing up

666
00:26:36,910 --> 00:26:31,010
there were only and now it's

667
00:26:41,650 --> 00:26:36,920
nine I guess alright people it out acid

668
00:26:45,280 --> 00:26:41,660
rain 1876 nights at r.i.p Pluto so but

669
00:26:46,540 --> 00:26:45,290
that was back earlier in the chat let me

670
00:26:48,310 --> 00:26:46,550
throw in another quick one that they had

671
00:26:50,500 --> 00:26:48,320
somebody had asked about some dread

672
00:26:53,590 --> 00:26:50,510
Medus asked do you have any idea about

673
00:26:58,240 --> 00:26:53,600
the temperature the plumes IRL oh yeah

674
00:27:00,640 --> 00:26:58,250
sure so the water and the plumes

675
00:27:04,720 --> 00:27:00,650
originate at the plate at the interface

676
00:27:07,390 --> 00:27:04,730
between the rocky surface and the ocean

677
00:27:11,350 --> 00:27:07,400
and the temperature is at that point our

678
00:27:13,600 --> 00:27:11,360
I think like quite high like 90 or 80 or

679
00:27:15,760 --> 00:27:13,610
90 Celsius and then it's pretty

680
00:27:17,770 --> 00:27:15,770
interesting so like at that interface

681
00:27:20,620 --> 00:27:17,780
there you have like the silica

682
00:27:22,390 --> 00:27:20,630
nanoparticles starting to form and the

683
00:27:24,820 --> 00:27:22,400
water then starts to make its way up and

684
00:27:27,790 --> 00:27:24,830
then as an exits you know obviously as

685
00:27:28,900 --> 00:27:27,800
it exits into space it freezes so like I

686
00:27:30,790 --> 00:27:28,910
don't know exactly what the temperature

687
00:27:32,740 --> 00:27:30,800
is but it's no longer in the liquid

688
00:27:34,060 --> 00:27:32,750
phase it's in the ice phase and so that

689
00:27:35,740 --> 00:27:34,070
creates a problem when you're trying to

690
00:27:37,870 --> 00:27:35,750
design a collector because you have to

691
00:27:40,540 --> 00:27:37,880
then take that sample and then remelt it

692
00:27:42,520 --> 00:27:40,550
in order to pull out any potential you

693
00:27:45,100 --> 00:27:42,530
know markers of life that you would be

694
00:27:46,270 --> 00:27:45,110
interested in analyzing so we're gonna

695
00:27:47,410 --> 00:27:46,280
eventually get to the point this is

696
00:27:49,990 --> 00:27:47,420
almost like wrapping up as these

697
00:27:52,150 --> 00:27:50,000
dangerous at the end yeah but there's

698
00:27:56,980 --> 00:27:52,160
our beautiful spacecraft as named at

699
00:27:59,260 --> 00:27:56,990
NASA Ames no sure if we zoom in on it oh

700
00:28:05,230 --> 00:27:59,270
nice oh we may have reached the end of

701
00:28:06,610 --> 00:28:05,240
the video itself so I do want to thank

702
00:28:09,520 --> 00:28:06,620
you as we're getting ready to transition

703
00:28:11,350 --> 00:28:09,530
over to a new game that's on on the iPad

704
00:28:13,750 --> 00:28:11,360
that we have over here I do want to give

705
00:28:15,040 --> 00:28:13,760
a shout out over to to to Eric our audio

706
00:28:17,650 --> 00:28:15,050
guy who's sitting over in the audio

707
00:28:20,740 --> 00:28:17,660
booth now he was pushing really hard to

708
00:28:21,850 --> 00:28:20,750
get no man's sky in on this one oh I

709
00:28:22,980 --> 00:28:21,860
believe that but it's not really

710
00:28:25,840 --> 00:28:22,990
scientific

711
00:28:27,070 --> 00:28:25,850
so well he was actually he'd gone in and

712
00:28:28,600 --> 00:28:27,080
like it played a little bit of elite

713
00:28:30,310 --> 00:28:28,610
dangerous so Eric I don't know you ever

714
00:28:32,530 --> 00:28:30,320
need questions anything's about you want

715
00:28:34,360 --> 00:28:32,540
to throw on over just Scott about elite

716
00:28:36,190 --> 00:28:34,370
dangerous cuz I know it's like I mean

717
00:28:37,600 --> 00:28:36,200
it's it's a pretty tough sim game

718
00:28:38,380 --> 00:28:37,610
there's like it's kind of hard to figure

719
00:28:40,750 --> 00:28:38,390
that out

720
00:28:43,090 --> 00:28:40,760
very hard in places for sure but I mean

721
00:28:44,950 --> 00:28:43,100
a lot of it is carried by the fact that

722
00:28:46,990 --> 00:28:44,960
is so beautiful sitting around in your

723
00:28:49,690 --> 00:28:47,000
spaceship and looking at planets yeah I

724
00:28:51,400 --> 00:28:49,700
totally totally agree yeah it was a lot

725
00:28:52,750 --> 00:28:51,410
of fun to play with and really cool to

726
00:28:54,850 --> 00:28:52,760
look at but definitely a steep learning

727
00:28:56,380 --> 00:28:54,860
curve yeah and I think it's the Sun guy

728
00:28:58,450 --> 00:28:56,390
you probably really appreciate the only

729
00:29:00,790 --> 00:28:58,460
way that game oh yeah yeah it's

730
00:29:02,830 --> 00:29:00,800
beautiful I want to try it out on the VR

731
00:29:04,570 --> 00:29:02,840
goggles now it just that would be a

732
00:29:05,950 --> 00:29:04,580
natural we were actually talking about

733
00:29:07,270 --> 00:29:05,960
that about how cool it would be to

734
00:29:09,760 --> 00:29:07,280
actually have somebody with the VR

735
00:29:11,380 --> 00:29:09,770
headset and and just actually today I

736
00:29:13,120 --> 00:29:11,390
ran by somebody who over on their desk

737
00:29:15,160 --> 00:29:13,130
they had an HTC vive and I was this

738
00:29:18,760 --> 00:29:15,170
close to just pulling it in but maybe

739
00:29:20,740 --> 00:29:18,770
that'll be for the next episode folks so

740
00:29:22,180 --> 00:29:20,750
yeah that's like switch on over to the

741
00:29:24,970 --> 00:29:22,190
next thing that we have set up here

742
00:29:27,730 --> 00:29:24,980
through the magic of an HDMI cable to an

743
00:29:30,070 --> 00:29:27,740
iPad I mean I came up with this idea

744
00:29:32,410 --> 00:29:30,080
during the last show you are showing all

745
00:29:34,450 --> 00:29:32,420
these console games you're showing PC

746
00:29:36,970 --> 00:29:34,460
games but not everybody has pcs or

747
00:29:39,300 --> 00:29:36,980
consoles many people have phones and

748
00:29:41,620 --> 00:29:39,310
there's a lot of actually really good

749
00:29:43,300 --> 00:29:41,630
simulation games for your rocket

750
00:29:46,000 --> 00:29:43,310
simulation essentially Kerbal space

751
00:29:48,010 --> 00:29:46,010
program clones that will run on mobile

752
00:29:49,720 --> 00:29:48,020
devices I'm running on an iPad because

753
00:29:52,270 --> 00:29:49,730
it's better but I've run this on like an

754
00:29:54,280 --> 00:29:52,280
old 5s so this is a space flight

755
00:29:56,050 --> 00:29:54,290
simulator your base our space simulator

756
00:29:58,090 --> 00:29:56,060
your I'm just trying to build a little

757
00:29:59,830 --> 00:29:58,100
rocket here we're just dragging the

758
00:30:04,300 --> 00:29:59,840
parts together and Mary Beth was

759
00:30:08,350 --> 00:30:04,310
launching stuff right before that if you

760
00:30:10,780 --> 00:30:08,360
like requirements right this is just the

761
00:30:12,760 --> 00:30:10,790
sandbox so I'm just I'm gonna try and

762
00:30:15,430 --> 00:30:12,770
put something up and into space you

763
00:30:18,040 --> 00:30:15,440
gotta find a big rocket I think this is

764
00:30:20,590 --> 00:30:18,050
gonna be way too big so yeah I mean this

765
00:30:22,600 --> 00:30:20,600
simulates the physics this is free we're

766
00:30:24,130 --> 00:30:22,610
in the basic mode and then you can pay a

767
00:30:25,540 --> 00:30:24,140
little extra for an expansion so it's

768
00:30:27,610 --> 00:30:25,550
actually really nice if you're

769
00:30:29,350 --> 00:30:27,620
interested in learning I Rockets work

770
00:30:31,240 --> 00:30:29,360
you don't have to pay extra further fuel

771
00:30:33,190 --> 00:30:31,250
you don't have to pay extra for the fuel

772
00:30:35,350 --> 00:30:33,200
but you know fuel is always the cheapest

773
00:30:37,570 --> 00:30:35,360
part of the rocket right compared to

774
00:30:38,500 --> 00:30:37,580
everything out oh that wasn't quite

775
00:30:40,030 --> 00:30:38,510
right well whatever

776
00:30:41,740 --> 00:30:40,040
well okay while you're sending that up

777
00:30:43,990 --> 00:30:41,750
we have a couple like comments from the

778
00:30:46,670 --> 00:30:44,000
stream one guy captain quasar asked for

779
00:30:49,460 --> 00:30:46,680
a 24 hour stream please

780
00:30:51,200 --> 00:30:49,470
we'll see what we do we normally aim for

781
00:30:52,550 --> 00:30:51,210
an hour but we have some stuff in store

782
00:30:54,560 --> 00:30:52,560
for you so it may go a little bit long

783
00:30:56,600 --> 00:30:54,570
it would get really boring when we sleep

784
00:30:59,120 --> 00:30:56,610
you'd be surprised the way you know over

785
00:31:01,790 --> 00:30:59,130
on Twitch people you know don't watch it

786
00:31:04,340 --> 00:31:01,800
yeah here let me throw this over to Chad

787
00:31:06,380 --> 00:31:04,350
cuz he said one question this comes from

788
00:31:08,690 --> 00:31:06,390
maker BRZ what kind of engineer do you

789
00:31:10,880 --> 00:31:08,700
need to even be to consider getting a

790
00:31:13,610 --> 00:31:10,890
job at NASA says I'm finishing is civil

791
00:31:16,160 --> 00:31:13,620
engineering and I wonder if if I can so

792
00:31:19,250 --> 00:31:16,170
amazingly we have civil engineers at

793
00:31:23,690 --> 00:31:19,260
NASA right because hey we have all sorts

794
00:31:26,060 --> 00:31:23,700
of projects that require moving you know

795
00:31:28,670 --> 00:31:26,070
everything from dirt facility

796
00:31:30,950 --> 00:31:28,680
construction you know we're just

797
00:31:33,590 --> 00:31:30,960
building out a whole new supercomputing

798
00:31:35,390 --> 00:31:33,600
pad right now there's been a whole lot

799
00:31:37,550 --> 00:31:35,400
of refurbishment down at Kennedy Space

800
00:31:41,090 --> 00:31:37,560
Center to get ready for the new larger

801
00:31:43,400 --> 00:31:41,100
rockets so pretty much any engineering

802
00:31:46,580 --> 00:31:43,410
discipline we have people doing that

803
00:31:48,890 --> 00:31:46,590
somewhere at NASA so pretty broad and so

804
00:31:52,760 --> 00:31:48,900
another question comes from evil mr.

805
00:31:54,350 --> 00:31:52,770
muffinz that is an awesome name what

806
00:31:56,210 --> 00:31:54,360
degree should I get to work at NASA

807
00:31:58,220 --> 00:31:56,220
there's a big old smiley face I guess I

808
00:32:00,260 --> 00:31:58,230
mean do I know this the science side

809
00:32:01,580 --> 00:32:00,270
very bad what would you if people who

810
00:32:02,840 --> 00:32:01,590
are asking you what should I study to

811
00:32:04,460 --> 00:32:02,850
get a job at NASA

812
00:32:05,990 --> 00:32:04,470
what would you say wow yeah there's a

813
00:32:07,550 --> 00:32:06,000
lot of options I mean I work with people

814
00:32:11,480 --> 00:32:07,560
who have degrees in physics biology

815
00:32:13,400 --> 00:32:11,490
chemistry astronomy you know I think the

816
00:32:14,630 --> 00:32:13,410
best course of action is just choose

817
00:32:16,760 --> 00:32:14,640
something you're like super passionate

818
00:32:19,010 --> 00:32:16,770
about because let me tell you it's a lot

819
00:32:20,600 --> 00:32:19,020
of school it's like 10 years of school

820
00:32:22,940 --> 00:32:20,610
after high school to get to this point

821
00:32:24,620 --> 00:32:22,950
of being a scientist at NASA you have to

822
00:32:26,540 --> 00:32:24,630
get your your bachelor's and something

823
00:32:29,180 --> 00:32:26,550
and then your PhD so if you don't really

824
00:32:30,350 --> 00:32:29,190
love what you're doing wrong well I've

825
00:32:31,730 --> 00:32:30,360
found that it's like there's a there's a

826
00:32:33,500 --> 00:32:31,740
job for everybody I mean like for me

827
00:32:35,360 --> 00:32:33,510
Andrea I'm probably the one person at

828
00:32:39,470 --> 00:32:35,370
the table without a science degree I'm

829
00:32:43,360 --> 00:32:39,480
guessing so my communications and

830
00:32:45,650 --> 00:32:43,370
poli-sci thing works out pretty well I

831
00:32:47,330 --> 00:32:45,660
appreciate that and on the future

832
00:32:50,840 --> 00:32:47,340
wonders or assigning roles I was sure to

833
00:32:51,470 --> 00:32:50,850
be put as the tourist actually meet you

834
00:32:52,669 --> 00:32:51,480
the pilot

835
00:32:56,389 --> 00:32:52,679
really

836
00:32:58,129 --> 00:32:56,399
nice right it's not just on the

837
00:33:00,379 --> 00:32:58,139
engineering side we employ all different

838
00:33:03,470 --> 00:33:00,389
shades and varieties of Engineers but

839
00:33:05,600 --> 00:33:03,480
across the board right NASA's a big

840
00:33:07,879 --> 00:33:05,610
complicated organization that does lots

841
00:33:10,460 --> 00:33:07,889
of amazing stuff and it takes a huge

842
00:33:14,180 --> 00:33:10,470
cast of supporting characters to make

843
00:33:16,820 --> 00:33:14,190
that all happen so hey everybody from

844
00:33:18,590 --> 00:33:16,830
you know the public safety net you know

845
00:33:20,450 --> 00:33:18,600
we've got NASA house cops we have

846
00:33:24,560 --> 00:33:20,460
firefighters we have lawyers we have

847
00:33:26,810 --> 00:33:24,570
people doing procurement literally every

848
00:33:28,159 --> 00:33:26,820
profession you can think of we we have

849
00:33:29,509 --> 00:33:28,169
people that are doing that so we're

850
00:33:31,700 --> 00:33:29,519
doing a podcast episode with somebody

851
00:33:34,399 --> 00:33:31,710
who actually went through budgeting and

852
00:33:36,259 --> 00:33:34,409
procurement but then eventually ended up

853
00:33:38,119 --> 00:33:36,269
doing a temporary assignment as a

854
00:33:40,039 --> 00:33:38,129
project manager and then they're doing

855
00:33:42,919 --> 00:33:40,049
more stuff and is on the technical side

856
00:33:44,210 --> 00:33:42,929
but with like you know yeah it's like a

857
00:33:47,239 --> 00:33:44,220
whole mix and you never know where you

858
00:33:50,359 --> 00:33:47,249
can end up so so but so Scott tell us

859
00:33:51,980 --> 00:33:50,369
what are we looking at whatever yeah

860
00:33:53,419 --> 00:33:51,990
I've just been flying a spacecraft into

861
00:33:56,090 --> 00:33:53,429
orbit well you guys were talking about

862
00:33:58,159 --> 00:33:56,100
although we flew spacecraft we flew it

863
00:34:00,019 --> 00:33:58,169
into orbit we are now actually in orbit

864
00:34:01,789 --> 00:34:00,029
so this was a simple two-stage rocket

865
00:34:04,159 --> 00:34:01,799
and I built everything by dragging and

866
00:34:06,470 --> 00:34:04,169
dropping and yeah you fired the main

867
00:34:07,879 --> 00:34:06,480
engine to boost us up into us kind of

868
00:34:09,680 --> 00:34:07,889
suborbital trajectory and then we

869
00:34:11,270 --> 00:34:09,690
circularized with this little engine so

870
00:34:13,010 --> 00:34:11,280
we're now here and honestly we're just

871
00:34:14,869 --> 00:34:13,020
gonna go back and because this is like

872
00:34:17,389 --> 00:34:14,879
what kind of altitude did you get well

873
00:34:20,450 --> 00:34:17,399
this is a scaled-down earth so our

874
00:34:22,789 --> 00:34:20,460
height is reaching up to 173 kilometers

875
00:34:24,980 --> 00:34:22,799
and that is not really to scale but it's

876
00:34:26,659 --> 00:34:24,990
nice to do to have scaled down Earth's

877
00:34:28,669 --> 00:34:26,669
because it means your orbits are faster

878
00:34:30,169 --> 00:34:28,679
so I'm just gonna actually call back

879
00:34:32,690 --> 00:34:30,179
now we're gonna land this so we're gonna

880
00:34:34,639 --> 00:34:32,700
reduce the time warp and then we're

881
00:34:37,039 --> 00:34:34,649
gonna perform a retrograde burn to

882
00:34:39,559 --> 00:34:37,049
slower or a bit down and bring the Peary

883
00:34:42,169 --> 00:34:39,569
apps our perigee inside the atmosphere

884
00:34:44,180 --> 00:34:42,179
so plane what is that the perigee is the

885
00:34:47,480 --> 00:34:44,190
point in the orbit which is closest to

886
00:34:49,849 --> 00:34:47,490
the planet Earth you have the perigee

887
00:34:51,500 --> 00:34:49,859
and the apogee so I'm at Apogee or it

888
00:34:54,260 --> 00:34:51,510
says apoapsis which is the general

889
00:34:56,000 --> 00:34:54,270
version perigee is over here and that is

890
00:34:57,190 --> 00:34:56,010
the closest point and you'll see there

891
00:35:00,589 --> 00:34:57,200
periapsis

892
00:35:03,289 --> 00:35:00,599
G implies this earth so you'll also get

893
00:35:05,450 --> 00:35:03,299
like peri jewel around Jupiter which is

894
00:35:06,089 --> 00:35:05,460
June all course from its distant apple

895
00:35:10,049 --> 00:35:06,099
Jove too

896
00:35:12,120 --> 00:35:10,059
close Parrish off and with parkour Solar

897
00:35:14,009 --> 00:35:12,130
Probe you can have perihelion when it's

898
00:35:16,950 --> 00:35:14,019
really close and getting very hot and

899
00:35:19,319 --> 00:35:16,960
aphelion when it's a long way out I'm

900
00:35:21,719 --> 00:35:19,329
just gonna fire my engine and the thrust

901
00:35:24,479 --> 00:35:21,729
is dropping my orbit down into the

902
00:35:27,479 --> 00:35:24,489
atmosphere and we're then gonna use that

903
00:35:29,219 --> 00:35:27,489
to descend and land yes nice so yeah and

904
00:35:31,370 --> 00:35:29,229
then I just wanted to show this this is

905
00:35:34,469 --> 00:35:31,380
space I think a Space Flight Simulator

906
00:35:38,039 --> 00:35:34,479
it's free and you can you get it on

907
00:35:40,829 --> 00:35:38,049
Android and everything Mac OS so or not

908
00:35:42,989 --> 00:35:40,839
Mac iOS so if you've got a phone if

909
00:35:46,380 --> 00:35:42,999
you're just interested in flying rockets

910
00:35:47,910 --> 00:35:46,390
this is a fantastic option for you there

911
00:35:49,170 --> 00:35:47,920
are some other ones I want to look at so

912
00:35:51,239 --> 00:35:49,180
we're now falling through the atmosphere

913
00:35:54,690 --> 00:35:51,249
and as we fall through the atmosphere

914
00:35:56,999 --> 00:35:54,700
the drag is gonna slower orbit down you

915
00:35:59,339 --> 00:35:57,009
can see down here that our Apple apps is

916
00:36:01,680 --> 00:35:59,349
decreasing because the atmosphere is

917
00:36:03,569 --> 00:36:01,690
slowing us down we're losing energy and

918
00:36:05,729 --> 00:36:03,579
so our orbit is getting closer and

919
00:36:07,499 --> 00:36:05,739
closer to the planet and eventually

920
00:36:08,940 --> 00:36:07,509
we're gonna slow down and have to use

921
00:36:10,410 --> 00:36:08,950
the parachute but we don't want to use

922
00:36:12,959 --> 00:36:10,420
the parachute just yet

923
00:36:17,910 --> 00:36:12,969
yeah because it will tear off at this

924
00:36:19,319 --> 00:36:17,920
speed yeah yes he's gonna have well you

925
00:36:21,930 --> 00:36:19,329
the fight these I think the first time

926
00:36:23,459 --> 00:36:21,940
for me playing Kerbal I was messing

927
00:36:25,469 --> 00:36:23,469
around with it just like trying to do a

928
00:36:27,900 --> 00:36:25,479
quick suborbital launch but I got really

929
00:36:29,459 --> 00:36:27,910
high and then as the as the rocket was

930
00:36:31,709 --> 00:36:29,469
going back in I'm like alright I'm gonna

931
00:36:33,749 --> 00:36:31,719
try to land this thing and I got the the

932
00:36:36,289 --> 00:36:33,759
whether the hatch or whatever it is and

933
00:36:38,640 --> 00:36:36,299
I have it pointing straight down just

934
00:36:40,709 --> 00:36:38,650
just steamrolling like we're like right

935
00:36:42,150 --> 00:36:40,719
to planet Earth they go in land and I

936
00:36:45,239 --> 00:36:42,160
started noticing the Kerbal was having a

937
00:36:47,700 --> 00:36:45,249
very bad time it was getting redder and

938
00:36:50,670 --> 00:36:47,710
redder and like I'm like what is going

939
00:36:52,950 --> 00:36:50,680
on why is this not working and I was

940
00:36:54,719 --> 00:36:52,960
fast and it's falling and then I

941
00:36:57,539 --> 00:36:54,729
remember the conversation that I had

942
00:37:00,839 --> 00:36:57,549
with with Jack Boyd on the podcast of

943
00:37:03,359 --> 00:37:00,849
the whole blunt face idea and I flipped

944
00:37:05,579 --> 00:37:03,369
it around everything cooled off and yeah

945
00:37:09,120 --> 00:37:05,589
I don't have the exact problem I'm going

946
00:37:10,829 --> 00:37:09,130
nose-first thankfully this doesn't model

947
00:37:13,799 --> 00:37:10,839
reentry heating or I would have burned

948
00:37:15,479 --> 00:37:13,809
off my parachute and killed my crew but

949
00:37:17,249 --> 00:37:15,489
we don't get to know the crew so we can

950
00:37:18,579 --> 00:37:17,259
just treat them as faceless entities

951
00:37:20,709 --> 00:37:18,589
well it's a simulation

952
00:37:21,969 --> 00:37:20,719
simulation yes it's very hard to serious

953
00:37:24,219 --> 00:37:21,979
aside from the atmospheric heating

954
00:37:24,999 --> 00:37:24,229
you're probably not stable going

955
00:37:28,209 --> 00:37:25,009
nose-first

956
00:37:30,549 --> 00:37:28,219
so the coins are stable in both

957
00:37:32,380 --> 00:37:30,559
directions and then mercury they had to

958
00:37:34,029 --> 00:37:32,390
have a little spoiler to flip it around

959
00:37:38,200 --> 00:37:34,039
if it came down the wrong way

960
00:37:40,989 --> 00:37:38,210
I remember yeah for Chad while you're

961
00:37:42,549 --> 00:37:40,999
sitting around in school I mean these

962
00:37:44,019 --> 00:37:42,559
kind of simulations have anything I mean

963
00:37:51,670 --> 00:37:44,029
we need people are doing engineering

964
00:37:56,859 --> 00:37:51,680
school this is anything like this 25

965
00:38:01,630 --> 00:37:56,869
year old Chad frost paper it's done

966
00:38:03,670 --> 00:38:01,640
slates and chalk so one of the first one

967
00:38:06,450 --> 00:38:03,680
of the first pieces of code I had to

968
00:38:12,009 --> 00:38:06,460
write for my engineering software class

969
00:38:16,239 --> 00:38:12,019
was a a three body simulation of orbital

970
00:38:18,130 --> 00:38:16,249
dynamics right so mmm anyone could have

971
00:38:19,809 --> 00:38:18,140
you know gone out and you've done a

972
00:38:22,029 --> 00:38:19,819
three body simulation that's it's not

973
00:38:24,069 --> 00:38:22,039
that hard but boy you sure learn a lot

974
00:38:26,410 --> 00:38:24,079
about orbital mechanics when you have to

975
00:38:28,150 --> 00:38:26,420
write the code yourself right it wasn't

976
00:38:29,319 --> 00:38:28,160
a sophisticated simulation about if

977
00:38:31,390 --> 00:38:29,329
there's no better way to learn the

978
00:38:33,430 --> 00:38:31,400
basics than to actually have to code it

979
00:38:35,950 --> 00:38:33,440
up and now there's all sorts of great

980
00:38:38,349 --> 00:38:35,960
simulations and tools I think are also

981
00:38:40,499 --> 00:38:38,359
really great ways to sort of learn

982
00:38:42,880 --> 00:38:40,509
what's going on you know

983
00:38:44,650 --> 00:38:42,890
perigee Apogee what are these terms

984
00:38:46,749 --> 00:38:44,660
meanwhile there's you can just look at

985
00:38:49,269 --> 00:38:46,759
that look at that little simulation and

986
00:38:51,459 --> 00:38:49,279
it's right there and it's very instantly

987
00:38:54,670 --> 00:38:51,469
intuitive in ways that just reading it

988
00:38:56,079 --> 00:38:54,680
out of a book might not be yeah I mean a

989
00:38:59,109 --> 00:38:56,089
lot of these stuff even like terms like

990
00:39:00,519 --> 00:38:59,119
Delta V Devers like I'd heard people

991
00:39:01,779 --> 00:39:00,529
talk about it but it wasn't until

992
00:39:04,660 --> 00:39:01,789
actually playing some of the games I'm

993
00:39:16,120 --> 00:39:04,670
like oh that's what they're talking

994
00:39:18,579 --> 00:39:16,130
about one here this is simple rockets

995
00:39:21,519 --> 00:39:18,589
which is very similar it's you know it's

996
00:39:23,739 --> 00:39:21,529
older it has soft body physics when you

997
00:39:25,870 --> 00:39:23,749
build really big rockets they can you

998
00:39:27,430 --> 00:39:25,880
know you can have things break but I was

999
00:39:30,820 --> 00:39:27,440
actually gonna hand this over to Marian

1000
00:39:32,890 --> 00:39:30,830
sue she can want to try landing this

1001
00:39:35,050 --> 00:39:32,900
and this is for folks if you did not

1002
00:39:37,030 --> 00:39:35,060
watch the the previous episode of us

1003
00:39:39,490 --> 00:39:37,040
doing let's play space videogames

1004
00:39:41,470 --> 00:39:39,500
marybeth landed the lunar lander the

1005
00:39:42,070 --> 00:39:41,480
first time without any practicing

1006
00:39:43,420 --> 00:39:42,080
whatsoever

1007
00:39:46,030 --> 00:39:43,430
solutely tells you to activate your

1008
00:39:48,520 --> 00:39:46,040
landing legs yeah there you go this is

1009
00:39:52,270 --> 00:39:48,530
high pressure man it's okay does not an

1010
00:39:53,830 --> 00:39:52,280
engineer the game really provides these

1011
00:40:01,960 --> 00:39:53,840
very helpful hints like you were falling

1012
00:40:03,130 --> 00:40:01,970
too fast but I did it yeah you know

1013
00:40:04,570 --> 00:40:03,140
could have turn off your engine they're

1014
00:40:06,820 --> 00:40:04,580
getting higher you still have to land

1015
00:40:09,250 --> 00:40:06,830
this thing I want to go back to space

1016
00:40:11,680 --> 00:40:09,260
what are you talking about there's more

1017
00:40:17,340 --> 00:40:11,690
science to find you pointed the wrong

1018
00:40:20,680 --> 00:40:17,350
way no no turn off your engines here

1019
00:40:23,380 --> 00:40:20,690
there you go no no you can point in that

1020
00:40:26,920 --> 00:40:23,390
direction well what are your 250 meters

1021
00:40:29,530 --> 00:40:26,930
up and there you go you pointed the

1022
00:40:31,690 --> 00:40:29,540
wrong way though there's no it's it's no

1023
00:40:33,220 --> 00:40:31,700
catching up there you go well what are

1024
00:40:35,140 --> 00:40:33,230
the questions from the chat this is from

1025
00:40:38,810 --> 00:40:35,150
no sink he was asking are you guys going

1026
00:40:41,910 --> 00:40:38,820
back to the moon and it's like yes

1027
00:40:47,140 --> 00:40:44,770
you've landed twice already yeah I just

1028
00:40:48,700 --> 00:40:47,150
I just love space so much yes just

1029
00:40:53,650 --> 00:40:48,710
doesn't want it to end I don't want to

1030
00:40:55,630 --> 00:40:53,660
go home but listen this the moon is this

1031
00:40:57,610 --> 00:40:55,640
is another version of the moon yes this

1032
00:41:13,680 --> 00:40:57,620
would appear to be a rocky rocky planet

1033
00:41:16,930 --> 00:41:13,690
yes secret magic powers of lunar lander

1034
00:41:19,240 --> 00:41:16,940
consistently every time sign me up

1035
00:41:22,570 --> 00:41:19,250
she is a part of the nasa ames video

1036
00:41:27,160 --> 00:41:22,580
game club but that's made me like mario

1037
00:41:28,630 --> 00:41:27,170
kart oh nice nice does anyone want to

1038
00:41:33,270 --> 00:41:28,640
try docking a spacecraft I think a

1039
00:41:34,730 --> 00:41:33,280
square I salute how's that chord go yeah

1040
00:41:37,040 --> 00:41:34,740
yeah we

1041
00:41:39,410 --> 00:41:37,050
this alright we'll have a head up

1042
00:41:40,850 --> 00:41:39,420
another one before we start as long we

1043
00:41:42,650 --> 00:41:40,860
need to do here you've gotta try and

1044
00:41:45,020 --> 00:41:42,660
dolt with these two spacecraft so it's

1045
00:41:47,030 --> 00:41:45,030
you know you've got controls at the

1046
00:41:48,470 --> 00:41:47,040
bottom there well let's figure out what

1047
00:41:51,290 --> 00:41:48,480
the controls do first

1048
00:41:54,380 --> 00:41:51,300
so exactly there you go then you get

1049
00:41:57,140 --> 00:41:54,390
translate rotate there you go

1050
00:41:59,830 --> 00:41:57,150
so you can drag yep this is very

1051
00:42:05,780 --> 00:41:59,840
realistic because there's no actual

1052
00:42:08,120 --> 00:42:05,790
attitude control its computer to go full

1053
00:42:10,670 --> 00:42:08,130
twitch stream or mode then I have chat

1054
00:42:17,420 --> 00:42:10,680
explain the model of ladee while he's

1055
00:42:19,730 --> 00:42:17,430
playing at the same time you know do two

1056
00:42:21,380 --> 00:42:19,740
things at once yeah just sort of how to

1057
00:42:25,970 --> 00:42:21,390
control it seems to be the hardest part

1058
00:42:27,890 --> 00:42:25,980
yeah one of the questions people were

1059
00:42:29,420 --> 00:42:27,900
asking about going back to the moon

1060
00:42:32,270 --> 00:42:29,430
obviously we're playing around with like

1061
00:42:33,859 --> 00:42:32,280
like landing on the moon and we have

1062
00:42:36,320 --> 00:42:33,869
some other things in the store later

1063
00:42:38,060 --> 00:42:36,330
moon focus but just recently and you

1064
00:42:39,920 --> 00:42:38,070
know not the last episode but the

1065
00:42:41,540 --> 00:42:39,930
previous episode of NASA Silicon Valley

1066
00:42:43,490 --> 00:42:41,550
live we had the administrator Jim

1067
00:42:46,310 --> 00:42:43,500
bridenstine on talked a lot about going

1068
00:42:47,990 --> 00:42:46,320
to the moon and and more particularly

1069
00:42:49,430 --> 00:42:48,000
talking about how it's not flags and

1070
00:42:51,260 --> 00:42:49,440
footprints like last time it's all about

1071
00:42:57,380 --> 00:42:51,270
getting commercial partners together

1072
00:43:00,320 --> 00:42:57,390
look at that you can try again so for

1073
00:43:02,150 --> 00:43:00,330
folks who may be listening as the audio

1074
00:43:03,680 --> 00:43:02,160
version of this podcast this might be

1075
00:43:06,740 --> 00:43:03,690
one maybe you're you're sitting in your

1076
00:43:09,470 --> 00:43:06,750
car on the 101 sitting in traffic this

1077
00:43:11,630 --> 00:43:09,480
might be the episode for you to pause

1078
00:43:14,359 --> 00:43:11,640
and like actually wait till you get home

1079
00:43:15,920 --> 00:43:14,369
they can watch it you know on-demand on

1080
00:43:19,370 --> 00:43:15,930
Twitter on YouTube because it might be a

1081
00:43:21,020 --> 00:43:19,380
more visually I'm just wondering wearing

1082
00:43:22,390 --> 00:43:21,030
the docking ports on this actually are

1083
00:43:25,809 --> 00:43:22,400
he might be

1084
00:43:27,910 --> 00:43:25,819
helps us I eat there how's that yeah

1085
00:43:34,140 --> 00:43:27,920
between those solar panels that's what

1086
00:43:37,359 --> 00:43:34,150
you go there over on the slide realistic

1087
00:43:39,160 --> 00:43:37,369
engineered docking ports there the

1088
00:43:40,779 --> 00:43:39,170
problem is I can't like flight over the

1089
00:43:42,579 --> 00:43:40,789
solar arrays I guess this is two

1090
00:43:45,160 --> 00:43:42,589
dimension piers like I have to go up

1091
00:43:46,690 --> 00:43:45,170
it's gonna say yeah you're supposed to

1092
00:43:49,269 --> 00:43:46,700
slide around like that and the other

1093
00:43:51,220 --> 00:43:49,279
thing that's no we did have one other

1094
00:43:53,049 --> 00:43:51,230
game but I I'm having trouble starting

1095
00:43:55,930 --> 00:43:53,059
it with the right now and I'm not sure

1096
00:43:58,660 --> 00:43:55,940
maybe we can try it towards the end but

1097
00:44:01,630 --> 00:43:58,670
we're hitting it about like what 15

1098
00:44:04,930 --> 00:44:01,640
minutes left so we'll pop on over to the

1099
00:44:07,420 --> 00:44:04,940
next once once we get Chad let's do this

1100
00:44:10,990 --> 00:44:07,430
you can do it Chad everybody believes in

1101
00:44:12,940 --> 00:44:11,000
you there we go just thread the needle

1102
00:44:14,529 --> 00:44:12,950
here and then I'll just jump in another

1103
00:44:18,400 --> 00:44:14,539
question from the chat this is from that

1104
00:44:19,960 --> 00:44:18,410
one fish is does studying in the field

1105
00:44:23,200 --> 00:44:19,970
of aerospace engineering help in

1106
00:44:26,500 --> 00:44:23,210
becoming an astronaut yes I would say

1107
00:44:30,640 --> 00:44:26,510
absolutely yes oh it hasn't worked for

1108
00:44:33,279 --> 00:44:30,650
me as a aerospace engineer I'm not yet

1109
00:44:34,809 --> 00:44:33,289
an astronaut so no guarantees well that

1110
00:44:38,170 --> 00:44:34,819
was one night remember I like to Steve

1111
00:44:40,299 --> 00:44:38,180
Smith he was he's our local astronaut

1112
00:44:42,160 --> 00:44:40,309
that we always default to he's from the

1113
00:44:44,410 --> 00:44:42,170
Bay Area when he talked them you know he

1114
00:44:46,210 --> 00:44:44,420
was an engineer and locally and then

1115
00:44:49,120 --> 00:44:46,220
eventually he took an engineering job at

1116
00:44:50,920 --> 00:44:49,130
NASA Johnson and I hate get applied to

1117
00:44:53,200 --> 00:44:50,930
the astronaut class like four or five

1118
00:44:54,480 --> 00:44:53,210
times until he finally got in so I'm

1119
00:44:56,920 --> 00:44:54,490
gonna say if you're applying to be an

1120
00:45:07,000 --> 00:44:56,930
astronaut life system you have to be

1121
00:45:08,529 --> 00:45:07,010
persistent because you never know now

1122
00:45:09,549 --> 00:45:08,539
I've got the set now I got the satellite

1123
00:45:11,920 --> 00:45:09,559
moving around

1124
00:45:16,920 --> 00:45:11,930
ya know you can know you're in a Salyut

1125
00:45:25,599 --> 00:45:23,799
almost wasn't pretty but it was

1126
00:45:27,069 --> 00:45:25,609
successful yes and you now have to

1127
00:45:28,720 --> 00:45:27,079
repair the solar panels but you're an

1128
00:45:30,760 --> 00:45:28,730
engineer so you can figure that out I'll

1129
00:45:31,839 --> 00:45:30,770
take that one so for folks who are just

1130
00:45:33,290 --> 00:45:31,849
jumping in what we're gonna do is we're

1131
00:45:35,960 --> 00:45:33,300
gonna transition to the next

1132
00:45:37,970 --> 00:45:35,970
to the next game which basically means

1133
00:45:41,570 --> 00:45:37,980
that Scott is gonna unplug one HDMI

1134
00:45:44,390 --> 00:45:41,580
cable and plug it into another PC here

1135
00:45:46,550 --> 00:45:44,400
but for our on the chat if you are

1136
00:45:50,240 --> 00:45:46,560
joining us live you're watching us on

1137
00:45:52,850 --> 00:45:50,250
twitch TV slash NASA that is where you

1138
00:45:57,200 --> 00:45:52,860
need to go in order to to join the chat

1139
00:45:59,090 --> 00:45:57,210
our friend Kavon is actually he's

1140
00:46:02,660 --> 00:45:59,100
actually moderating and then he's the

1141
00:46:03,710 --> 00:46:02,670
NASA behind behind on the chat so yeah

1142
00:46:06,230 --> 00:46:03,720
so go ahead and send in those questions

1143
00:46:08,180 --> 00:46:06,240
in fact we may just jump in yeah go to

1144
00:46:09,170 --> 00:46:08,190
twitch.tv slash NASA I'm gonna do a

1145
00:46:13,400 --> 00:46:09,180
quick rapid-fire

1146
00:46:15,800 --> 00:46:13,410
as we get the next game all riled up but

1147
00:46:17,600 --> 00:46:15,810
also in fact even as we're doing this I

1148
00:46:20,690 --> 00:46:17,610
could do a shout out over to Bill and

1149
00:46:27,260 --> 00:46:20,700
Dave over in the the bill and Dave cam

1150
00:46:29,120 --> 00:46:27,270
so bill Dave it's like do you guys have

1151
00:46:30,590 --> 00:46:29,130
any questions for the group as we start

1152
00:46:34,130 --> 00:46:30,600
getting things transitioned over about

1153
00:46:36,380 --> 00:46:34,140
these games well I no not really but I

1154
00:46:39,440 --> 00:46:36,390
can't come up with one what I was just

1155
00:46:41,990 --> 00:46:39,450
wondering is how do game designers have

1156
00:46:44,750 --> 00:46:42,000
to balance the the fact of space

1157
00:46:47,030 --> 00:46:44,760
exploration by nature is kind of boring

1158
00:46:49,520 --> 00:46:47,040
because it takes so long and we can't go

1159
00:46:52,700 --> 00:46:49,530
very fast versus all the entertainment

1160
00:46:55,070 --> 00:46:52,710
value of things like hyperspace things

1161
00:46:56,750 --> 00:46:55,080
like you know how how do you think game

1162
00:46:59,920 --> 00:46:56,760
designers come up with a good balance

1163
00:47:02,540 --> 00:46:59,930
between making it fun and making it real

1164
00:47:04,190 --> 00:47:02,550
Wow yeah I mean games they love to

1165
00:47:06,320 --> 00:47:04,200
include time warp for all those boring

1166
00:47:08,030 --> 00:47:06,330
things so that you basically run time

1167
00:47:10,190 --> 00:47:08,040
forward so you don't have to spend a

1168
00:47:12,320 --> 00:47:10,200
whole week traveling to the moon you may

1169
00:47:13,640 --> 00:47:12,330
want to click on the space bar or maybe

1170
00:47:16,280 --> 00:47:13,650
on the map that's what I've been trying

1171
00:47:19,460 --> 00:47:16,290
it's trying to get the next game place

1172
00:47:22,330 --> 00:47:19,470
this thing is hot but yeah I mean

1173
00:47:25,550 --> 00:47:22,340
balancing game design is really you know

1174
00:47:27,530 --> 00:47:25,560
fascinating question the staff at these

1175
00:47:29,210 --> 00:47:27,540
things work but with Kerbal also it

1176
00:47:31,010 --> 00:47:29,220
helps you have lots of explosions so

1177
00:47:33,890 --> 00:47:31,020
there's lots of moments of Terror and

1178
00:47:36,590 --> 00:47:33,900
fire and then the rest of the time is

1179
00:47:38,570 --> 00:47:36,600
very slow and maybe trying to figure out

1180
00:47:40,490 --> 00:47:38,580
your orbital rendezvous and very

1181
00:47:42,710 --> 00:47:40,500
carefully put you put together

1182
00:47:45,250 --> 00:47:42,720
there's also this interesting balance

1183
00:47:47,410 --> 00:47:45,260
between your realism

1184
00:47:49,690 --> 00:47:47,420
and playability right so you can have

1185
00:47:53,260 --> 00:47:49,700
something that's that really models the

1186
00:47:54,520 --> 00:47:53,270
physics very authentically but at the

1187
00:47:57,190 --> 00:47:54,530
same time if you make it too authentic

1188
00:47:59,200 --> 00:47:57,200
right in the game I was just playing if

1189
00:48:00,700 --> 00:47:59,210
I had bumped my little spacecraft into

1190
00:48:02,380 --> 00:48:00,710
the satellite right there would have

1191
00:48:04,360 --> 00:48:02,390
been death and destruction all over well

1192
00:48:06,190 --> 00:48:04,370
that happens in Kerbal space program did

1193
00:48:08,260 --> 00:48:06,200
that so there's this trade between why

1194
00:48:10,540 --> 00:48:08,270
do I make it so authentic that it's

1195
00:48:13,060 --> 00:48:10,550
unplayable or do i back off a little bit

1196
00:48:15,370 --> 00:48:13,070
on the authenticity and have enough

1197
00:48:17,320 --> 00:48:15,380
realism but still make it kind of a fun

1198
00:48:19,210 --> 00:48:17,330
to play game we should fly space

1199
00:48:20,500 --> 00:48:19,220
simulator instead I know well you know

1200
00:48:23,440 --> 00:48:20,510
what we're gonna do in fact what I'm

1201
00:48:25,480 --> 00:48:23,450
gonna try and do so Chad so I'm gonna

1202
00:48:28,630 --> 00:48:25,490
flip on over because this is the joy of

1203
00:48:31,720 --> 00:48:28,640
being on live television on twitch.tv

1204
00:48:34,000 --> 00:48:31,730
slash NASA is that sometimes even when

1205
00:48:36,400 --> 00:48:34,010
you have the game working for an hour

1206
00:48:38,860 --> 00:48:36,410
plus before we went live sometimes

1207
00:48:41,560 --> 00:48:38,870
things tend to go wrong and that's okay

1208
00:48:42,790 --> 00:48:41,570
so I'm gonna hop on over to go see if I

1209
00:48:45,010 --> 00:48:42,800
can get that thing up and running

1210
00:48:48,910 --> 00:48:45,020
because it's actually my personal PC

1211
00:48:51,010 --> 00:48:48,920
which is for whatever reason the cable

1212
00:48:52,900 --> 00:48:51,020
isn't working I'm not sure if the if

1213
00:48:54,850 --> 00:48:52,910
it's too hot or whatever but I mean it's

1214
00:48:57,160 --> 00:48:54,860
like turn it over to to my friend Chad

1215
00:48:58,930 --> 00:48:57,170
over here to look at this to look at the

1216
00:49:00,820 --> 00:48:58,940
chat and so we can start rapid-fire

1217
00:49:02,830 --> 00:49:00,830
through some questions okay

1218
00:49:04,600 --> 00:49:02,840
so why don't you just go through here

1219
00:49:06,130 --> 00:49:04,610
and I'm gonna hop on over to see if I

1220
00:49:07,420 --> 00:49:06,140
can help Scott over there alright we're

1221
00:49:10,140 --> 00:49:07,430
just gonna go right down from the top

1222
00:49:12,970 --> 00:49:10,150
rapid-fire all right can you explain

1223
00:49:16,540 --> 00:49:12,980
lagravis this is from snack liske herbal

1224
00:49:19,050 --> 00:49:16,550
I guess he's hungry up in space I'm sure

1225
00:49:22,420 --> 00:49:19,060
so the garage points are those

1226
00:49:24,790 --> 00:49:22,430
interesting spots in our in our solar

1227
00:49:27,130 --> 00:49:24,800
system where the the gravitational

1228
00:49:27,670 --> 00:49:27,140
attraction of different bodies cancel

1229
00:49:30,400 --> 00:49:27,680
each other out

1230
00:49:32,680 --> 00:49:30,410
all right so we have Lagrange points

1231
00:49:36,280 --> 00:49:32,690
between Earth and the moon between Earth

1232
00:49:41,020 --> 00:49:36,290
and the Sun where if you you know put a

1233
00:49:43,450 --> 00:49:41,030
put a spacecraft at that point it's sort

1234
00:49:45,910 --> 00:49:43,460
of right in this nice little point of

1235
00:49:48,430 --> 00:49:45,920
balance between them and so you can't

1236
00:49:50,230 --> 00:49:48,440
they don't just sit there of their own

1237
00:49:52,090 --> 00:49:50,240
accord they typically have to be sort of

1238
00:49:55,390 --> 00:49:52,100
a little bit of a drift around that

1239
00:49:57,310 --> 00:49:55,400
point to be stable but it let's but lets

1240
00:49:58,470 --> 00:49:57,320
us put some scientific spacecraft out

1241
00:50:00,269 --> 00:49:58,480
there

1242
00:50:02,819 --> 00:50:00,279
and they don't have to use a lot of fuel

1243
00:50:05,759 --> 00:50:02,829
to stay there and they're not in an

1244
00:50:07,200 --> 00:50:05,769
orbit around the Earth there they're

1245
00:50:09,359 --> 00:50:07,210
nice and far away they can do their

1246
00:50:12,720 --> 00:50:09,369
science very Beth you get anything you

1247
00:50:14,549 --> 00:50:12,730
want to understand I was thinking about

1248
00:50:16,680 --> 00:50:14,559
like what are the cool missions or

1249
00:50:18,930 --> 00:50:16,690
spacecraft that we have at lagrangian's

1250
00:50:19,650 --> 00:50:18,940
right now like I know James Webb where

1251
00:50:25,259 --> 00:50:19,660
is that one going

1252
00:50:29,099 --> 00:50:25,269
nothing else : exactly but it's a common

1253
00:50:30,509 --> 00:50:29,109
place to go park big big experiments

1254
00:50:32,999 --> 00:50:30,519
things that need to be out there for a

1255
00:50:35,160 --> 00:50:33,009
long time and then you've also got Lucie

1256
00:50:37,559 --> 00:50:35,170
which is planning to actually visit the

1257
00:50:40,289 --> 00:50:37,569
Julian Lagrange points where you've got

1258
00:50:42,059 --> 00:50:40,299
these asteroids these very old asteroids

1259
00:50:43,440 --> 00:50:42,069
that have been trapped there since the

1260
00:50:45,809 --> 00:50:43,450
formation of the solar system

1261
00:50:49,349 --> 00:50:45,819
so headed out there to get a close look

1262
00:50:51,239 --> 00:50:49,359
at these things of course one of the one

1263
00:50:53,519 --> 00:50:51,249
of the challenges for example with the

1264
00:50:56,430 --> 00:50:53,529
James Webb Space Telescope is you know

1265
00:50:58,529 --> 00:50:56,440
it's a far distance out there so once we

1266
00:51:00,359 --> 00:50:58,539
send something there we can't just at

1267
00:51:02,039 --> 00:51:00,369
this point send astronauts out to go fix

1268
00:51:04,890 --> 00:51:02,049
it if there's a problem it really has to

1269
00:51:09,329 --> 00:51:04,900
be pretty self-sufficient okay next one

1270
00:51:13,769 --> 00:51:09,339
on the list from test has ace can people

1271
00:51:17,220 --> 00:51:13,779
live on the moon for how long is that a

1272
00:51:19,710 --> 00:51:17,230
real answer I think if you magically

1273
00:51:21,420 --> 00:51:19,720
dropped somebody teleported them onto

1274
00:51:24,749 --> 00:51:21,430
the moon they could live there for you

1275
00:51:28,019 --> 00:51:24,759
know a few moments it would be longer if

1276
00:51:30,299 --> 00:51:28,029
they had a spacesuit longer yet if they

1277
00:51:31,589 --> 00:51:30,309
had some protection from the radiation

1278
00:51:34,109 --> 00:51:31,599
environment and the heat and the cold

1279
00:51:37,170 --> 00:51:34,119
some sort of a habitat so as long as we

1280
00:51:39,930 --> 00:51:37,180
provide them with the necessary habitat

1281
00:51:42,900 --> 00:51:39,940
that sure eventually we have to feed

1282
00:51:45,120 --> 00:51:42,910
them so they know you know snack less

1283
00:51:47,309 --> 00:51:45,130
Kerbal may be hungry because we already

1284
00:51:50,789 --> 00:51:47,319
gave the food to the people living on

1285
00:51:52,079 --> 00:51:50,799
the moon snacks are the fundamental unit

1286
00:51:53,970 --> 00:51:52,089
of life supports in the carville

1287
00:51:57,960 --> 00:51:53,980
universe they don't run out of air they

1288
00:52:01,660 --> 00:51:57,970
run out of snacks snacks okay it looks

1289
00:52:04,210 --> 00:52:01,670
like these guys have it running yeah

1290
00:52:05,650 --> 00:52:04,220
rebidding so you're not quite there but

1291
00:52:08,500 --> 00:52:05,660
we're actually gonna end up doing is

1292
00:52:10,720 --> 00:52:08,510
like hey how you doing so what we're

1293
00:52:12,190 --> 00:52:10,730
gonna end up doing is it is booting up

1294
00:52:14,680 --> 00:52:12,200
right now so we're gonna go do some more

1295
00:52:15,910 --> 00:52:14,690
rapid-fire before we go ahead and jump

1296
00:52:18,760 --> 00:52:15,920
on in so I'm gonna hop over there

1297
00:52:20,200 --> 00:52:18,770
everything yeah okay well yeah I'm just

1298
00:52:22,960 --> 00:52:20,210
wondering if we unplug this whether old

1299
00:52:24,700 --> 00:52:22,970
break it or not well I think the things

1300
00:52:27,250 --> 00:52:24,710
that we won't be able to get steam up

1301
00:52:27,940 --> 00:52:27,260
and running game going so let's just

1302
00:52:32,410 --> 00:52:27,950
keep going this

1303
00:52:36,010 --> 00:52:32,420
let's keep answering questions decided

1304
00:52:37,780 --> 00:52:36,020
to do a Windows Update it's a Windows

1305
00:52:40,599 --> 00:52:37,790
Update that's what happened it's so

1306
00:52:42,640 --> 00:52:40,609
funny okay welcome to live television

1307
00:52:46,960 --> 00:52:42,650
folks there's a good one for Marybeth

1308
00:52:49,569 --> 00:52:46,970
shade of dead he says what about rain on

1309
00:52:52,000 --> 00:52:49,579
Venus on Venus oh I don't I think it's

1310
00:52:54,370 --> 00:52:52,010
too hot what would be rain in the upper

1311
00:52:56,589 --> 00:52:54,380
atmosphere apparently but it evaporates

1312
00:52:58,510 --> 00:52:56,599
before it hits the surface okay that's

1313
00:53:01,539 --> 00:52:58,520
what I've I've seen some evidence of

1314
00:53:02,740 --> 00:53:01,549
that and it was supporting an NIAC air

1315
00:53:05,620 --> 00:53:02,750
stream and that we're talking about a

1316
00:53:07,839 --> 00:53:05,630
balloon that would look at this and also

1317
00:53:09,190 --> 00:53:07,849
considered looking at dust they would be

1318
00:53:12,670 --> 00:53:09,200
blown up from the surface because of the

1319
00:53:14,410 --> 00:53:12,680
very dense atmosphere I think also at

1320
00:53:17,589 --> 00:53:14,420
this point we don't think we you know we

1321
00:53:19,900 --> 00:53:17,599
have there's hypotheses we've talked

1322
00:53:22,030 --> 00:53:19,910
about sending a new generation of probes

1323
00:53:24,250 --> 00:53:22,040
to Venus at some point it's been a long

1324
00:53:26,020 --> 00:53:24,260
time since we sent any it may be that'd

1325
00:53:29,470 --> 00:53:26,030
be a great question to try and seek

1326
00:53:32,200 --> 00:53:29,480
answers to yeah let's see

1327
00:53:34,450 --> 00:53:32,210
so robotics this is from ki-netic so

1328
00:53:47,740 --> 00:53:34,460
robotics will have to advanced for us to

1329
00:53:49,750 --> 00:53:47,750
advance in outer space steam by the way

1330
00:53:53,200 --> 00:53:49,760
we're gonna send we're gonna send humans

1331
00:53:56,140 --> 00:53:53,210
deeper into space and that we're gonna

1332
00:53:57,819 --> 00:53:56,150
send robots right alongside them you

1333
00:54:01,839 --> 00:53:57,829
know right now one of the one of the

1334
00:54:04,450 --> 00:54:01,849
NASA plans is to have a future you know

1335
00:54:06,010 --> 00:54:04,460
outpost in the vicinity of the moon and

1336
00:54:08,589 --> 00:54:06,020
we're not going to be able to have

1337
00:54:10,329 --> 00:54:08,599
humans there full-time humans might be

1338
00:54:12,430 --> 00:54:10,339
there you know a month out of the year

1339
00:54:14,049 --> 00:54:12,440
and so the question is well how do we

1340
00:54:14,970 --> 00:54:14,059
take care of the place the rest of the

1341
00:54:17,849 --> 00:54:14,980
other 11 months

1342
00:54:19,920 --> 00:54:17,859
of the year so we really need to have

1343
00:54:21,800 --> 00:54:19,930
some robots to help with that we talked

1344
00:54:24,330 --> 00:54:21,810
earlier about having robots help build

1345
00:54:26,220 --> 00:54:24,340
the future things that we're going to

1346
00:54:29,010 --> 00:54:26,230
have in space like habitats and space

1347
00:54:31,980 --> 00:54:29,020
stations so yeah I think especially the

1348
00:54:33,830 --> 00:54:31,990
further out into space we go the more

1349
00:54:37,800 --> 00:54:33,840
robotics we'll need and the more

1350
00:54:40,530 --> 00:54:37,810
autonomy we'll have to have as well so

1351
00:54:42,660 --> 00:54:40,540
we are getting steam booted up the game

1352
00:54:45,359 --> 00:54:42,670
is about to go and ladies and gentlemen

1353
00:54:46,770 --> 00:54:45,369
my laptop just died so we're gonna keep

1354
00:54:52,380 --> 00:54:46,780
doing some questions but I'm gonna do

1355
00:54:53,790 --> 00:54:52,390
this from my mobile phone because it is

1356
00:54:55,980 --> 00:54:53,800
live television so it's going to be

1357
00:54:57,480 --> 00:54:55,990
really fun but let me jump on into the

1358
00:54:59,849 --> 00:54:57,490
chat which I have some stuff right here

1359
00:55:02,010 --> 00:54:59,859
okay what information can be gathered

1360
00:55:07,320 --> 00:55:02,020
from the newly landed Japanese probes on

1361
00:55:09,480 --> 00:55:07,330
ragu obviously cameras on there right

1362
00:55:11,820 --> 00:55:09,490
now but these people should appreciate

1363
00:55:14,280 --> 00:55:11,830
these are just the first of many Landers

1364
00:55:15,930 --> 00:55:14,290
there's gonna be a second Lander and a

1365
00:55:18,390 --> 00:55:15,940
third and they're also gonna shoot it

1366
00:55:21,060 --> 00:55:18,400
with an anti-tank round to make a hole

1367
00:55:24,000 --> 00:55:21,070
on it so they can get a sample yeah the

1368
00:55:26,450 --> 00:55:24,010
real GU asteroid I'm fascinated by this

1369
00:55:28,890 --> 00:55:26,460
because it's a very very

1370
00:55:30,780 --> 00:55:28,900
undifferentiated kind of rock so it's

1371
00:55:32,640 --> 00:55:30,790
gonna give us some real interesting old

1372
00:55:34,520 --> 00:55:32,650
look at the kind of pristine material

1373
00:55:37,440 --> 00:55:34,530
from the solar system early solar system

1374
00:55:39,150 --> 00:55:37,450
I'm a big fan of that the old school you

1375
00:55:40,890 --> 00:55:39,160
know if you want to know what it's made

1376
00:55:42,630 --> 00:55:40,900
of and what its characteristics are you

1377
00:55:44,430 --> 00:55:42,640
know poke it with a stick yeah so

1378
00:55:45,840 --> 00:55:44,440
they're gonna hit it hard and then

1379
00:55:47,400 --> 00:55:45,850
they're gonna bring a sample from

1380
00:55:48,560 --> 00:55:47,410
underneath the surface back home

1381
00:55:51,480 --> 00:55:48,570
eventually

1382
00:55:53,550 --> 00:55:51,490
so I'm also just kind of realizing how

1383
00:55:56,430 --> 00:55:53,560
like a lot of the stuff that we worked

1384
00:55:59,130 --> 00:55:56,440
on before we started if they dip the

1385
00:56:01,620 --> 00:55:59,140
save if the computer actually say oh you

1386
00:56:02,250 --> 00:56:01,630
did save it yes we actually have Kerbal

1387
00:56:04,500 --> 00:56:02,260
up note

1388
00:56:07,020 --> 00:56:04,510
all right so spoiler ladies and

1389
00:56:09,870 --> 00:56:07,030
gentlemen that our third and final game

1390
00:56:11,490 --> 00:56:09,880
for the evening is going to be an encore

1391
00:56:13,290 --> 00:56:11,500
presentation of Kerrville Jessie I'm

1392
00:56:15,270 --> 00:56:13,300
good if we think we have like three

1393
00:56:16,560 --> 00:56:15,280
minutes liquor bowls so this is what

1394
00:56:18,330 --> 00:56:16,570
we're gonna basically end up doing

1395
00:56:20,790 --> 00:56:18,340
because we have we normally go for about

1396
00:56:21,990 --> 00:56:20,800
an hour and so let's throw it up to the

1397
00:56:23,310 --> 00:56:22,000
chat you know we got about like two

1398
00:56:24,780 --> 00:56:23,320
minutes I think we're just gonna go for

1399
00:56:27,780 --> 00:56:24,790
another half hour

1400
00:56:29,760 --> 00:56:27,790
and let's keep the keep the party going

1401
00:56:30,960 --> 00:56:29,770
and we're gonna get Kerbal up and

1402
00:56:34,050 --> 00:56:30,970
running and so we have that going on

1403
00:56:36,240 --> 00:56:34,060
behind us right now yes so I know you

1404
00:56:37,890 --> 00:56:36,250
mentioned that NASA doesn't necessarily

1405
00:56:39,990 --> 00:56:37,900
endorse anything but they did actually

1406
00:56:42,180 --> 00:56:40,000
work with the developers actually a

1407
00:56:44,940 --> 00:56:42,190
space act agreement where there was an

1408
00:56:48,090 --> 00:56:44,950
Tenten and yeah they added the parts to

1409
00:56:50,610 --> 00:56:48,100
make the SLS in Kerbal space program and

1410
00:56:53,760 --> 00:56:50,620
this was a slightly older version of the

1411
00:56:55,890 --> 00:56:53,770
SLS with a different paintwork so it

1412
00:56:58,020 --> 00:56:55,900
doesn't have the sweeps or whatever on

1413
00:57:00,210 --> 00:56:58,030
the external boosters but I built up

1414
00:57:02,520 --> 00:57:00,220
something that's pretty close to a it

1415
00:57:04,440 --> 00:57:02,530
looks a block one roughly it's obvious

1416
00:57:06,870 --> 00:57:04,450
the Kerbal scale but it has a crew of

1417
00:57:09,210 --> 00:57:06,880
three we have an Orion spacecraft at the

1418
00:57:12,930 --> 00:57:09,220
top this is a hypergolic upper stage so

1419
00:57:15,180 --> 00:57:12,940
it actually oh wait a second that's not

1420
00:57:16,920 --> 00:57:15,190
the I've missed I'm missing a stage here

1421
00:57:19,110 --> 00:57:16,930
oh no did we miss the stage I'm missing

1422
00:57:22,620 --> 00:57:19,120
a stage go check your staging I gotta

1423
00:57:26,130 --> 00:57:22,630
check my stage sorry for folk audio

1424
00:57:28,340 --> 00:57:26,140
listeners yes because yes the the upper

1425
00:57:31,170 --> 00:57:28,350
stage on the block one is gonna use for

1426
00:57:33,420 --> 00:57:31,180
rl10 engines and then it's gonna use an

1427
00:57:34,890 --> 00:57:33,430
AGA ten hypergolic engine on the final

1428
00:57:37,680 --> 00:57:34,900
stage but the mainstage is going to be

1429
00:57:40,470 --> 00:57:37,690
powered by liquid hydrogen and oxygen

1430
00:57:43,230 --> 00:57:40,480
and for these rs.25 engines which were

1431
00:57:45,800 --> 00:57:43,240
the same engines that powered the space

1432
00:57:50,180 --> 00:57:45,810
shuttle those things are absolutely

1433
00:57:53,130 --> 00:57:50,190
impressively enormous I was out there

1434
00:57:55,290 --> 00:57:53,140
standing next to one of those not long

1435
00:57:57,810 --> 00:57:55,300
ago and I didn't fully appreciate just

1436
00:57:59,430 --> 00:57:57,820
how huge they were until I was standing

1437
00:58:00,930 --> 00:57:59,440
right next to one of them and it just

1438
00:58:03,150 --> 00:58:00,940
kind of was looking up just at the

1439
00:58:07,200 --> 00:58:03,160
engine is my oh my goodness that's just

1440
00:58:08,940 --> 00:58:07,210
huge yeah yeah the rs.25 engines are

1441
00:58:11,940 --> 00:58:08,950
still right up there as some of the best

1442
00:58:13,380 --> 00:58:11,950
engines ever developed and everybody's

1443
00:58:17,970 --> 00:58:13,390
you know in terms of specific impulse

1444
00:58:19,410 --> 00:58:17,980
they're way out there and newer engines

1445
00:58:20,910 --> 00:58:19,420
are switching over to different fuel

1446
00:58:22,680 --> 00:58:20,920
cycles but they're not gonna get the

1447
00:58:24,990 --> 00:58:22,690
same efficiency and so basically what

1448
00:58:27,240 --> 00:58:25,000
we're trying to do here this is SLS em1

1449
00:58:28,770 --> 00:58:27,250
is what I always hear referred to yes so

1450
00:58:34,250 --> 00:58:28,780
don't you guys explain to me what is

1451
00:58:38,780 --> 00:58:34,260
e-m1 for us for the noobs what is that

1452
00:58:42,170 --> 00:58:38,790
is the upcoming sort of test mission to

1453
00:58:42,589 --> 00:58:42,180
take the system out around the moon and

1454
00:58:45,710 --> 00:58:42,599
back

1455
00:58:47,240 --> 00:58:45,720
alright so yeah I'm one as is the first

1456
00:58:48,920 --> 00:58:47,250
one that will take the the complete

1457
00:58:50,000 --> 00:58:48,930
system up and out and around the moon

1458
00:58:52,849 --> 00:58:50,010
and back

1459
00:58:57,680 --> 00:58:52,859
won't have any crew on board have a

1460
00:58:59,630 --> 00:58:57,690
whole bunch of experiments the SLS is

1461
00:59:02,930 --> 00:58:59,640
carrying along with it in addition to

1462
00:59:04,400 --> 00:59:02,940
the Orion on the top it's actually

1463
00:59:09,200 --> 00:59:04,410
carrying along a whole bunch of

1464
00:59:11,720 --> 00:59:09,210
additional cube sets around the the

1465
00:59:13,880 --> 00:59:11,730
interim cryogenic propulsion stages ICPs

1466
00:59:16,310 --> 00:59:13,890
sort of that big conical ring down there

1467
00:59:18,620 --> 00:59:16,320
and on its way out it will deploy a

1468
00:59:20,870 --> 00:59:18,630
whole bunch of those little secondary

1469
00:59:22,400 --> 00:59:20,880
spacecraft too so it's doing a whole

1470
00:59:24,020 --> 00:59:22,410
bunch of interesting things on that

1471
00:59:34,910 --> 00:59:24,030
mission so we see those boosters just

1472
00:59:37,130 --> 00:59:34,920
fell off ya know it's launching from

1473
00:59:40,040 --> 00:59:37,140
Kerbal Space Center I don't remember

1474
00:59:46,010 --> 00:59:40,050
that ASC though there's not many

1475
00:59:49,460 --> 00:59:46,020
mountains but yeah there's no boats out

1476
00:59:51,410 --> 00:59:49,470
there yeah there are some islands that

1477
00:59:52,460 --> 00:59:51,420
you can land on so this is one of the

1478
00:59:54,470 --> 00:59:52,470
great things about Kerbal space program

1479
00:59:56,690 --> 00:59:54,480
is it's been around for like eight years

1480
00:59:59,359 --> 00:59:56,700
now and I mentioned that people that

1481
01:00:01,670 --> 00:59:59,369
have played this game are actually now

1482
01:00:04,430 --> 01:00:01,680
working at NASA what are you like yes

1483
01:00:06,079 --> 01:00:04,440
change people's you know views and

1484
01:00:08,569 --> 01:00:06,089
turned them into actual rocket

1485
01:00:10,280 --> 01:00:08,579
scientists but the great thing about

1486
01:00:13,220 --> 01:00:10,290
Kerbal space program is it is

1487
01:00:16,880 --> 01:00:13,230
essentially simulating these Rockets as

1488
01:00:18,680 --> 01:00:16,890
multiple parts I'm gonna just throw it

1489
01:00:20,150 --> 01:00:18,690
alone my main engine so I guess we're

1490
01:00:22,790 --> 01:00:20,160
gonna carry our main stage because we're

1491
01:00:24,670 --> 01:00:22,800
gonna go out to the moon so right now

1492
01:00:27,650 --> 01:00:24,680
we're just kind of holding attitude I

1493
01:00:29,599 --> 01:00:27,660
was gonna say related to what you were

1494
01:00:31,250 --> 01:00:29,609
just talking about I recently had gone

1495
01:00:32,329 --> 01:00:31,260
through like a training over at Wallops

1496
01:00:35,420 --> 01:00:32,339
and there was a couple of people from

1497
01:00:37,160 --> 01:00:35,430
you know from Marshall and they had seen

1498
01:00:38,720 --> 01:00:37,170
the previous episode where we were doing

1499
01:00:41,120 --> 01:00:38,730
kerbals Facebook and they they were

1500
01:00:42,770 --> 01:00:41,130
quite like they're very adamant that you

1501
01:00:45,109 --> 01:00:42,780
really need to get some people from the

1502
01:00:46,670 --> 01:00:45,119
Marshall Space Flight Center onto the

1503
01:00:47,109 --> 01:00:46,680
show to play some Kerbal because there's

1504
01:00:49,150 --> 01:00:47,119
old

1505
01:00:51,849 --> 01:00:49,160
got incredible fans over at Marshalls

1506
01:00:56,529 --> 01:00:51,859
good those guys know way more about

1507
01:00:58,959 --> 01:00:56,539
rockets than we do we are not rocket

1508
01:01:01,209 --> 01:00:58,969
folks here no no we need to know about

1509
01:01:01,890 --> 01:01:01,219
rock as we go ask them those guys are

1510
01:01:05,289 --> 01:01:01,900
the experts

1511
01:01:06,940 --> 01:01:05,299
well yeah music herbal uses a slightly

1512
01:01:08,589 --> 01:01:06,950
smaller version of reality that

1513
01:01:10,719 --> 01:01:08,599
everything is scaled down by a factor of

1514
01:01:11,920 --> 01:01:10,729
10 and that makes it kind of easier for

1515
01:01:14,739 --> 01:01:11,930
the players because they have to spend

1516
01:01:16,809 --> 01:01:14,749
less time trying to chase down targets

1517
01:01:18,489 --> 01:01:16,819
for docking and everything space is big

1518
01:01:21,489 --> 01:01:18,499
if you make it smaller it makes things

1519
01:01:23,529 --> 01:01:21,499
easier but you know physics wise the

1520
01:01:25,779 --> 01:01:23,539
game engine models the thrust from the

1521
01:01:30,039 --> 01:01:25,789
Rockets the aerodynamics the thermal

1522
01:01:31,989 --> 01:01:30,049
transfer power flow you know you get it

1523
01:01:34,569 --> 01:01:31,999
all in there and and it kind of the

1524
01:01:36,640 --> 01:01:34,579
natural behavior of aircraft and rockets

1525
01:01:39,609 --> 01:01:36,650
all just comes out of modeling it like

1526
01:01:42,219 --> 01:01:39,619
this you can even have your Rockets

1527
01:01:45,279 --> 01:01:42,229
disintegrate at max Q because you over

1528
01:01:46,989 --> 01:01:45,289
stress the airframe like it has mainly

1529
01:01:48,549 --> 01:01:46,999
if the great thing is you play this game

1530
01:01:50,890 --> 01:01:48,559
and there'll be a failure and your

1531
01:01:52,359 --> 01:01:50,900
rocket explodes and you can typically

1532
01:01:54,729 --> 01:01:52,369
think back to some point in the past

1533
01:01:57,549 --> 01:01:54,739
where real rocket did exactly the same

1534
01:01:59,229 --> 01:01:57,559
thing for the same reason so I'm just

1535
01:02:00,700 --> 01:01:59,239
gonna I'm just putting ourselves into

1536
01:02:02,499 --> 01:02:00,710
orbit I think I'm gonna try going out to

1537
01:02:05,469 --> 01:02:02,509
the moon right now or we could you know

1538
01:02:07,150 --> 01:02:05,479
go somewhere else we have a pretty big

1539
01:02:09,549 --> 01:02:07,160
rocket here I think I gave it way more

1540
01:02:11,499 --> 01:02:09,559
fuel and we need it we actually carried

1541
01:02:13,779 --> 01:02:11,509
the entire first stage and talked about

1542
01:02:15,880 --> 01:02:13,789
the first day we still a fuel in it so

1543
01:02:17,529 --> 01:02:15,890
we might as well use that let's go

1544
01:02:20,259 --> 01:02:17,539
somewhere we're gonna head out to the

1545
01:02:22,440 --> 01:02:20,269
moon here so to travel to the moon we

1546
01:02:29,349 --> 01:02:22,450
have to perform what's called a trans

1547
01:02:30,329 --> 01:02:29,359
trans moon or injection in this case yes

1548
01:02:32,920 --> 01:02:30,339
TMI

1549
01:02:34,809 --> 01:02:32,930
so what you can actually do is use the

1550
01:02:36,969 --> 01:02:34,819
navigation computer you click on the

1551
01:02:38,380 --> 01:02:36,979
orbit to create what's called a maneuver

1552
01:02:40,930 --> 01:02:38,390
nord and then you say it this maneuver i

1553
01:02:43,239 --> 01:02:40,940
want to add some thrust and you can see

1554
01:02:46,239 --> 01:02:43,249
that it's showing you after this

1555
01:02:48,009 --> 01:02:46,249
maneuver that my orbit will go up so we

1556
01:02:50,309 --> 01:02:48,019
want this orbit to go up towards the

1557
01:02:53,769 --> 01:02:50,319
moon and I've carefully placed this

1558
01:02:55,450 --> 01:02:53,779
noise so that it should put me near the

1559
01:02:57,219 --> 01:02:55,460
moon you see and it's actually telling

1560
01:02:58,569 --> 01:02:57,229
it's gonna actually be moving while

1561
01:02:59,089 --> 01:02:58,579
you're trying to get it so you're kind

1562
01:03:01,309 --> 01:02:59,099
of interested

1563
01:03:02,960 --> 01:03:01,319
yes I've there we go we're actually

1564
01:03:04,880 --> 01:03:02,970
gonna get an encounter with the moon

1565
01:03:06,680 --> 01:03:04,890
there and then get kicked off into a

1566
01:03:09,950 --> 01:03:06,690
slightly different orbit but I think we

1567
01:03:11,569 --> 01:03:09,960
can well as we're on our way over to the

1568
01:03:15,349 --> 01:03:11,579
moon we'll throw that over to the chat

1569
01:03:17,420 --> 01:03:15,359
and Kavon will let me know do you guys

1570
01:03:20,059 --> 01:03:17,430
want to keep do we want to go to the

1571
01:03:23,509 --> 01:03:20,069
moon land or circle around and come back

1572
01:03:24,950 --> 01:03:23,519
or do we want to go somewhere else so go

1573
01:03:26,749 --> 01:03:24,960
ahead and jump into the chat and let us

1574
01:03:30,229 --> 01:03:26,759
know what you want to do yeah I'm gonna

1575
01:03:32,029 --> 01:03:30,239
I'm gonna take this do this oh I'm just

1576
01:03:35,809 --> 01:03:32,039
gonna use time acceleration to get here

1577
01:03:37,969 --> 01:03:35,819
so warps annex maneuver yes it's so Mary

1578
01:03:39,890 --> 01:03:37,979
Beth as a scientist it's like you know

1579
01:03:43,099 --> 01:03:39,900
coming up with experiments it's looking

1580
01:03:44,870 --> 01:03:43,109
like astrobiology um it's kind of I

1581
01:03:46,759 --> 01:03:44,880
don't know how much time do you guys

1582
01:03:49,789 --> 01:03:46,769
spent thinking about this kind of stuff

1583
01:03:51,499 --> 01:03:49,799
of just like getting into orbit and it's

1584
01:03:52,940 --> 01:03:51,509
just like this is the engineers world or

1585
01:03:54,469 --> 01:03:52,950
how often do you guys like like work

1586
01:03:57,200 --> 01:03:54,479
together yeah I mean it's really

1587
01:03:58,969 --> 01:03:57,210
important to understand you know how the

1588
01:04:01,190 --> 01:03:58,979
engineering is gonna impact whatever

1589
01:04:03,349 --> 01:04:01,200
instrument payload you're developing and

1590
01:04:04,910 --> 01:04:03,359
so it's important for especially even

1591
01:04:06,859 --> 01:04:04,920
early on to start to think about those

1592
01:04:09,499 --> 01:04:06,869
types of problems so you can you can

1593
01:04:11,719 --> 01:04:09,509
make sure that whatever experiment

1594
01:04:14,089 --> 01:04:11,729
you're trying to do no part of launch or

1595
01:04:18,200 --> 01:04:14,099
getting into space will affect that

1596
01:04:19,549 --> 01:04:18,210
experiment so I often think of there's

1597
01:04:22,549 --> 01:04:19,559
people here at Ames who are creating

1598
01:04:23,900 --> 01:04:22,559
like you know like experiments right and

1599
01:04:25,609 --> 01:04:23,910
they're they're putting them together in

1600
01:04:26,930 --> 01:04:25,619
this nice little box that they send over

1601
01:04:30,200 --> 01:04:26,940
and get launched in a rocket and I'm

1602
01:04:31,910 --> 01:04:30,210
like your experimental activity exactly

1603
01:04:33,620 --> 01:04:31,920
it's like surviving like a launch is a

1604
01:04:36,589 --> 01:04:33,630
pretty traumatic thing for whatever is

1605
01:04:38,029 --> 01:04:36,599
in that experiment and in that box yeah

1606
01:04:39,620 --> 01:04:38,039
the test drive scene you know the test

1607
01:04:42,049 --> 01:04:39,630
rigs that they use for all this and this

1608
01:04:44,509 --> 01:04:42,059
vibration heats the electrical

1609
01:04:46,789 --> 01:04:44,519
interference is you know yeah acoustic

1610
01:04:48,920 --> 01:04:46,799
Zac cycling it's yeah it's pretty brutal

1611
01:04:51,709 --> 01:04:48,930
one of my good friends works over at

1612
01:04:53,479 --> 01:04:51,719
Goddard and they have this beautiful

1613
01:04:55,999 --> 01:04:53,489
like I don't even know how to describe

1614
01:04:58,849 --> 01:04:56,009
it there it's like where all the

1615
01:05:00,920 --> 01:04:58,859
spacecraft get born intestine and like

1616
01:05:03,709 --> 01:05:00,930
the size of the thermal vac chambers is

1617
01:05:05,180 --> 01:05:03,719
huge and and on my friend gives us like

1618
01:05:06,739 --> 01:05:05,190
excellent tour and at the end of the

1619
01:05:09,640 --> 01:05:06,749
tour she takes you like downstairs into

1620
01:05:13,670 --> 01:05:09,650
the basement where they have

1621
01:05:16,570 --> 01:05:13,680
seamstresses who actually like so to get

1622
01:05:18,950 --> 01:05:16,580
like they cut out and sew together the

1623
01:05:22,850 --> 01:05:18,960
like the spacecraft blankets like the

1624
01:05:24,290 --> 01:05:22,860
things that but like it you know you

1625
01:05:26,570 --> 01:05:24,300
think that you were at like a fabric

1626
01:05:28,460 --> 01:05:26,580
store like nope you're like using this

1627
01:05:29,960 --> 01:05:28,470
amazing material that help like insulate

1628
01:05:31,940 --> 01:05:29,970
it and she's a thermal engineer so she

1629
01:05:33,710 --> 01:05:31,950
really cares about that that stage so

1630
01:05:36,560 --> 01:05:33,720
that stuff's hard to so I tried it once

1631
01:05:38,900 --> 01:05:36,570
really a bunch of layers of super super

1632
01:05:41,720 --> 01:05:38,910
super thin kinda like mylar

1633
01:05:43,910 --> 01:05:41,730
yeah it's slippery it's quickly you

1634
01:05:47,330 --> 01:05:43,920
train so you can't do it on a sewing

1635
01:05:49,670 --> 01:05:47,340
machine I least I couldn't sew something

1636
01:05:53,570 --> 01:05:49,680
from the chat we have dial our 42 is

1637
01:05:55,880 --> 01:05:53,580
saying send chat on a spacewalk is this

1638
01:05:58,430 --> 01:05:55,890
something we can do on route yeah we

1639
01:05:59,780 --> 01:05:58,440
yeah I mean they did that with Apollo on

1640
01:06:01,790 --> 01:05:59,790
the way back they had to go in a

1641
01:06:03,830 --> 01:06:01,800
spacewalk to recover one of the cameras

1642
01:06:05,270 --> 01:06:03,840
I'm just putting this into a slight I'm

1643
01:06:06,680 --> 01:06:05,280
putting this into an orbit that will

1644
01:06:10,160 --> 01:06:06,690
swing over the North Pole of the moon

1645
01:06:11,900 --> 01:06:10,170
here so yeah on route yeah let's get out

1646
01:06:13,940 --> 01:06:11,910
for a little spacewalk here this is that

1647
01:06:15,560 --> 01:06:13,950
Chad and that's oh yeah there we go we

1648
01:06:18,800 --> 01:06:15,570
have the nature and picture is right

1649
01:06:21,950 --> 01:06:18,810
over there we go there's Chad and I

1650
01:06:24,740 --> 01:06:21,960
guess I'm just gonna they're just gonna

1651
01:06:27,350 --> 01:06:24,750
let go and hey way to go Ted you're

1652
01:06:31,820 --> 01:06:27,360
doing great did I do I have a tether no

1653
01:06:34,460 --> 01:06:31,830
no you but you do have a you can fly

1654
01:06:36,260 --> 01:06:34,470
around I think you're super excited as

1655
01:06:38,240 --> 01:06:36,270
long as I have a jetpack I'm good yeah

1656
01:06:40,790 --> 01:06:38,250
you're good now look we can see the

1657
01:06:44,000 --> 01:06:40,800
rocket with all this we still have fuel

1658
01:06:45,920 --> 01:06:44,010
in that main tank I think I haven't

1659
01:06:48,980 --> 01:06:45,930
really SPECT this up I put this together

1660
01:06:50,510 --> 01:06:48,990
very quickly but yeah you know with this

1661
01:06:51,980 --> 01:06:50,520
game I mean it's tough I told you how

1662
01:06:56,000 --> 01:06:51,990
they scaled everything down by a factor

1663
01:06:57,380 --> 01:06:56,010
of 10 well you know you can actually mod

1664
01:07:00,020 --> 01:06:57,390
the game up to make it a hundred percent

1665
01:07:01,390 --> 01:07:00,030
realistic and try to replicate real

1666
01:07:03,950 --> 01:07:01,400
spacecraft

1667
01:07:05,300 --> 01:07:03,960
so as Chad's doing a spacewalk I'm gonna

1668
01:07:08,090 --> 01:07:05,310
keep jumping into the check there's a

1669
01:07:09,740 --> 01:07:08,100
whole bunch of questions in here this is

1670
01:07:11,900 --> 01:07:09,750
kind of thing I'm looking happier now

1671
01:07:14,270 --> 01:07:11,910
but you're having a good time still kind

1672
01:07:14,480 --> 01:07:14,280
of green curly chad is super happy right

1673
01:07:15,780 --> 01:07:14,490
now

1674
01:07:18,330 --> 01:07:15,790
Dramamine in there

1675
01:07:19,740 --> 01:07:18,340
exactly yeah so one of the questions

1676
01:07:21,360 --> 01:07:19,750
from the chat this is from seriously

1677
01:07:23,580 --> 01:07:21,370
gaming asks what are the opinions of

1678
01:07:26,250 --> 01:07:23,590
gravitational waves are you all excited

1679
01:07:28,230 --> 01:07:26,260
for gravitational astronomy no that

1680
01:07:31,020 --> 01:07:28,240
might be a little bit out of I'm very

1681
01:07:33,930 --> 01:07:31,030
excited I mean I University at Glasgow

1682
01:07:35,880 --> 01:07:33,940
where I yeah my alma mater they they did

1683
01:07:38,070 --> 01:07:35,890
a lot of this work on this and it's

1684
01:07:39,930 --> 01:07:38,080
really fascinating to see this stuff

1685
01:07:42,720 --> 01:07:39,940
that was talked about you know when I

1686
01:07:44,970 --> 01:07:42,730
was at university 20 years ago finally

1687
01:07:47,030 --> 01:07:44,980
working finally showing off finally

1688
01:07:49,170 --> 01:07:47,040
getting results

1689
01:07:50,640 --> 01:07:49,180
Chad Meredith that's fall into your

1690
01:07:53,010 --> 01:07:50,650
world cuz I think the funny thing about

1691
01:07:55,740 --> 01:07:53,020
like it Ames is there's a little bit of

1692
01:07:57,300 --> 01:07:55,750
everything so we have astrobiology next

1693
01:07:59,340 --> 01:07:57,310
to the supercomputing next to the

1694
01:08:00,180 --> 01:07:59,350
aeronautics next to engineering and

1695
01:08:02,100 --> 01:08:00,190
small SATs

1696
01:08:04,860 --> 01:08:02,110
so there's a whole mismatch of like

1697
01:08:05,910 --> 01:08:04,870
disciplines at this Center so but I

1698
01:08:09,300 --> 01:08:05,920
don't know because like interact with

1699
01:08:11,910 --> 01:08:09,310
that is not sure yeah not happy hour not

1700
01:08:13,440 --> 01:08:11,920
space yeah happy hours about it the one

1701
01:08:16,320 --> 01:08:13,450
thing I was thinking about in terms of

1702
01:08:18,990 --> 01:08:16,330
gravitational waves right is so one of

1703
01:08:21,210 --> 01:08:19,000
the things we do here at Ames is you

1704
01:08:23,039 --> 01:08:21,220
know especially small spacecraft or

1705
01:08:27,329 --> 01:08:23,049
missions with lots of small spacecraft

1706
01:08:29,340 --> 01:08:27,339
and there's the potential to you know do

1707
01:08:31,260 --> 01:08:29,350
some really fascinating science with

1708
01:08:32,940 --> 01:08:31,270
these little or little or spacecraft but

1709
01:08:35,670 --> 01:08:32,950
it depends on having you know really

1710
01:08:37,440 --> 01:08:35,680
small compact instruments as well and we

1711
01:08:39,320 --> 01:08:37,450
were talking to some colleagues at one

1712
01:08:41,880 --> 01:08:39,330
of the other government agencies about

1713
01:08:45,390 --> 01:08:41,890
really really tiny highly highly

1714
01:08:47,730 --> 01:08:45,400
sensitive magnetometers yeah I had the

1715
01:08:49,349 --> 01:08:47,740
thought well I wonder if you could put

1716
01:08:52,650 --> 01:08:49,359
those in a small spacecraft and use that

1717
01:08:54,720 --> 01:08:52,660
to do some research in the gravitational

1718
01:08:56,460 --> 01:08:54,730
wave area I don't know the answer I'm

1719
01:08:59,160 --> 01:08:56,470
not the not the scientist to answer the

1720
01:09:00,900 --> 01:08:59,170
question but and I know but I know a guy

1721
01:09:02,820 --> 01:09:00,910
and it really intrigued me as to the

1722
01:09:06,630 --> 01:09:02,830
possibilities were embarking into this

1723
01:09:09,150 --> 01:09:06,640
whole new this new age a new new era of

1724
01:09:12,420 --> 01:09:09,160
being able to kind of go down this new

1725
01:09:15,480 --> 01:09:12,430
path of research and we don't yet know

1726
01:09:18,240 --> 01:09:15,490
how to do some of it so it's exciting

1727
01:09:19,950 --> 01:09:18,250
it's also that came up in the chat one

1728
01:09:22,410 --> 01:09:19,960
of the comments has been let's go to the

1729
01:09:24,720 --> 01:09:22,420
Moon or Mars or and since the name of

1730
01:09:26,519 --> 01:09:24,730
the game has been moon to Mars but like

1731
01:09:28,399 --> 01:09:26,529
speaking of which the moon we have this

1732
01:09:29,840 --> 01:09:28,409
ladee model sitting right in

1733
01:09:31,760 --> 01:09:29,850
if you could talk a little bit about

1734
01:09:33,260 --> 01:09:31,770
what the ladee model is what ladee did

1735
01:09:34,970 --> 01:09:33,270
and even Mary Beth it's like there's

1736
01:09:36,829 --> 01:09:34,980
like the moon is still right for science

1737
01:09:38,660 --> 01:09:36,839
there's a lot of stuff that we I mean

1738
01:09:40,160 --> 01:09:38,670
you think about it was in the 70s was

1739
01:09:42,349 --> 01:09:40,170
the last time we actually had footprints

1740
01:09:44,539 --> 01:09:42,359
on the moon but since then we learned a

1741
01:09:47,749 --> 01:09:44,549
whole lot more about like how much water

1742
01:09:49,459 --> 01:09:47,759
ice is there's quite crazy sadhana the

1743
01:09:55,520 --> 01:09:49,469
delicate model that I tried to move

1744
01:09:57,290 --> 01:09:55,530
earlier it's supposed to come apart Matt

1745
01:09:59,419 --> 01:09:57,300
so I figured we're talking about

1746
01:10:01,790 --> 01:09:59,429
spacecraft it's always good to have a

1747
01:10:03,590 --> 01:10:01,800
toy to you know sort of illustrate

1748
01:10:05,330 --> 01:10:03,600
questions as they come up and this

1749
01:10:08,990 --> 01:10:05,340
happens to be a model of our of our

1750
01:10:11,330 --> 01:10:09,000
ladee spacecraft that went and orbited

1751
01:10:14,629 --> 01:10:11,340
the moon lots and lots and lots of times

1752
01:10:17,629 --> 01:10:14,639
a few years ago doing doing amazing

1753
01:10:19,760 --> 01:10:17,639
science and now is in many many tiny

1754
01:10:21,740 --> 01:10:19,770
little pieces on the surface because at

1755
01:10:24,530 --> 01:10:21,750
the end of its mission we just crashed

1756
01:10:28,729 --> 01:10:24,540
it into the surface carefully avoiding

1757
01:10:31,760 --> 01:10:28,739
any historical artifacts but right so

1758
01:10:34,000 --> 01:10:31,770
that ladee is a good example of what you

1759
01:10:36,800 --> 01:10:34,010
can do with a comparatively low-cost

1760
01:10:39,140 --> 01:10:36,810
spacecraft right this is something not

1761
01:10:42,620 --> 01:10:39,150
just not just actual size but it is to

1762
01:10:44,750 --> 01:10:42,630
scale this was about the size of a you

1763
01:10:48,770 --> 01:10:44,760
know of a refrigerator right good sized

1764
01:10:51,260 --> 01:10:48,780
refrigerator and and it was designed as

1765
01:10:53,090 --> 01:10:51,270
a as a modular spacecraft so as

1766
01:10:54,830 --> 01:10:53,100
different missions came along we could

1767
01:10:56,810 --> 01:10:54,840
reconfigure it to the needs of the

1768
01:10:58,459 --> 01:10:56,820
mission right you might not need all

1769
01:11:01,100 --> 01:10:58,469
these different pieces you might just

1770
01:11:03,470 --> 01:11:01,110
need the top piece and one of the bottom

1771
01:11:05,330 --> 01:11:03,480
pieces right propulsion depending on

1772
01:11:07,129 --> 01:11:05,340
okay depending on what you were doing we

1773
01:11:09,200 --> 01:11:07,139
designed a version of this that was a

1774
01:11:11,000 --> 01:11:09,210
little bit bigger it had two more of

1775
01:11:14,660 --> 01:11:11,010
these middle segments that could do a

1776
01:11:16,790 --> 01:11:14,670
Mars mission for example right and the

1777
01:11:18,950 --> 01:11:16,800
cool thing is right we can now do all

1778
01:11:21,620 --> 01:11:18,960
this amazing science with smaller

1779
01:11:24,740 --> 01:11:21,630
spacecraft because the our ability to

1780
01:11:27,169 --> 01:11:24,750
squeeze the science into smaller more

1781
01:11:29,300 --> 01:11:27,179
compact and more efficient instruments

1782
01:11:32,060 --> 01:11:29,310
has allowed us to do more with smaller

1783
01:11:34,070 --> 01:11:32,070
spacecraft so it opens up all these new

1784
01:11:36,500 --> 01:11:34,080
opportunities for folks like Mary Beth

1785
01:11:38,209 --> 01:11:36,510
like okay we can actually go do some

1786
01:11:41,310 --> 01:11:38,219
amazing stuff with with little tiny

1787
01:11:44,100 --> 01:11:41,320
spacecraft now JPL has the

1788
01:11:46,890 --> 01:11:44,110
Marco cube sets right there the size of

1789
01:11:50,130 --> 01:11:46,900
a briefcase and they're on their way out

1790
01:11:52,680 --> 01:11:50,140
to support the latest Mars mission so

1791
01:11:55,500 --> 01:11:52,690
there there's just so much potential and

1792
01:11:58,020 --> 01:11:55,510
it's enabled in part by technology in

1793
01:12:00,330 --> 01:11:58,030
part by new ways of thinking about

1794
01:12:02,100 --> 01:12:00,340
science so I see that we're from behind

1795
01:12:04,950 --> 01:12:02,110
us we are at the moon right now yeah I'm

1796
01:12:06,240 --> 01:12:04,960
trying to we have a lunar gateway in

1797
01:12:08,790 --> 01:12:06,250
orbit around the moon I figured it's

1798
01:12:10,230 --> 01:12:08,800
let's go and visit it might as well

1799
01:12:12,810 --> 01:12:10,240
we're going slightly further than what

1800
01:12:15,480 --> 01:12:12,820
e-m1 as because somebody's got a space

1801
01:12:17,310 --> 01:12:15,490
station there already oh nice I'm just

1802
01:12:18,870 --> 01:12:17,320
trying to match orbital planes with it

1803
01:12:20,760 --> 01:12:18,880
so we can perform this rendezvous and

1804
01:12:22,260 --> 01:12:20,770
yeah actually that's pushed me out of

1805
01:12:23,850 --> 01:12:22,270
the sphere of influence will figure this

1806
01:12:24,660 --> 01:12:23,860
Omar while you're figuring that out Mary

1807
01:12:27,750 --> 01:12:24,670
Beth why don't you talk a little bit

1808
01:12:29,490 --> 01:12:27,760
about what about the moon that you see

1809
01:12:32,010 --> 01:12:29,500
like interesting or you know as a

1810
01:12:33,330 --> 01:12:32,020
planetary scientist yeah there's so many

1811
01:12:36,270 --> 01:12:33,340
interesting things about the moon that

1812
01:12:37,620 --> 01:12:36,280
we're still learning it's I think the

1813
01:12:39,630 --> 01:12:37,630
most interesting thing about the Moon is

1814
01:12:43,050 --> 01:12:39,640
that it came from Earth right like it

1815
01:12:45,720 --> 01:12:43,060
was formed by very early on in Earth's

1816
01:12:48,240 --> 01:12:45,730
history by an object that was believed

1817
01:12:50,250 --> 01:12:48,250
to be about the size of Mars impacting

1818
01:12:54,090 --> 01:12:50,260
the proto-earth and then turning into

1819
01:12:56,400 --> 01:12:54,100
this this object right and you know I

1820
01:12:58,290 --> 01:12:56,410
think about this often times from an

1821
01:13:00,060 --> 01:12:58,300
astro biological perspective it's like

1822
01:13:02,580 --> 01:13:00,070
what what is it what is so special about

1823
01:13:04,740 --> 01:13:02,590
Earth to allow life to develop and

1824
01:13:06,600 --> 01:13:04,750
evolve and I think the moon is a big

1825
01:13:08,340 --> 01:13:06,610
part of that story because if you if you

1826
01:13:11,220 --> 01:13:08,350
look at the far side of the Moon it's

1827
01:13:12,690 --> 01:13:11,230
littered with with craters and so what

1828
01:13:14,550 --> 01:13:12,700
does that mean it means that things that

1829
01:13:17,490 --> 01:13:14,560
would have if there was no moon would

1830
01:13:20,340 --> 01:13:17,500
have impacted earth and instead hit the

1831
01:13:23,550 --> 01:13:20,350
moon and maybe protected you know early

1832
01:13:27,000 --> 01:13:23,560
life on earth and allowed it to to

1833
01:13:29,670 --> 01:13:27,010
continue to evolve but I think it's one

1834
01:13:33,180 --> 01:13:29,680
of the coolest discoveries in the last

1835
01:13:35,340 --> 01:13:33,190
10 years was a mission that Kate was out

1836
01:13:37,020 --> 01:13:35,350
of Ames called El cross and what

1837
01:13:38,820 --> 01:13:37,030
happened with El cross is they took the

1838
01:13:42,210 --> 01:13:38,830
upper stage of a rocket and they

1839
01:13:44,430 --> 01:13:42,220
actually impacted the still the one of

1840
01:13:48,060 --> 01:13:44,440
the so called permanently shadowed

1841
01:13:50,340 --> 01:13:48,070
craters on the moon and within those

1842
01:13:52,440 --> 01:13:50,350
craters they actually found evidence for

1843
01:13:54,660 --> 01:13:52,450
for water and so why do we care about

1844
01:13:57,540 --> 01:13:54,670
that especially if we start

1845
01:13:59,189 --> 01:13:57,550
thinking about you know going and living

1846
01:14:01,740 --> 01:13:59,199
on the moon that's a resource that could

1847
01:14:03,650 --> 01:14:01,750
be potentially used in stitch you so I

1848
01:14:06,270 --> 01:14:03,660
thought that was a pretty cool design

1849
01:14:08,820 --> 01:14:06,280
for a mission they you know they didn't

1850
01:14:10,380 --> 01:14:08,830
land anything they just impacted kicked

1851
01:14:11,610 --> 01:14:10,390
up a bunch of dust and then analyzed and

1852
01:14:13,890 --> 01:14:11,620
flew through the dust I think that's a

1853
01:14:17,729 --> 01:14:13,900
really cool cool design one of the big

1854
01:14:20,130 --> 01:14:17,739
questions now for for our return to the

1855
01:14:23,820 --> 01:14:20,140
moon is you know what's the distribution

1856
01:14:25,380 --> 01:14:23,830
of the various materials present on the

1857
01:14:26,939 --> 01:14:25,390
surface of the Moon right so okay we

1858
01:14:29,939 --> 01:14:26,949
know there's water now we know that

1859
01:14:32,550 --> 01:14:29,949
there's actually quite a bit of ice not

1860
01:14:34,260 --> 01:14:32,560
buried necessarily but near or on the

1861
01:14:37,350 --> 01:14:34,270
surface especially in some of these

1862
01:14:39,660 --> 01:14:37,360
shadowed craters okay well you know

1863
01:14:41,550 --> 01:14:39,670
where is it how much is there how do we

1864
01:14:43,350 --> 01:14:41,560
get it what do we do with it they're all

1865
01:14:44,760 --> 01:14:43,360
really important questions that need to

1866
01:14:47,490 --> 01:14:44,770
be answered if we want to have any sort

1867
01:14:48,930 --> 01:14:47,500
of a presence there like a long-term

1868
01:14:51,120 --> 01:14:48,940
President Walter present second the

1869
01:14:52,530 --> 01:14:51,130
Apollo era we went and we were tourists

1870
01:14:54,990 --> 01:14:52,540
we were visitors but we didn't stay for

1871
01:14:56,880 --> 01:14:55,000
very long so much since since those

1872
01:14:57,900 --> 01:14:56,890
initial flags and footprints well even

1873
01:15:00,000 --> 01:14:57,910
with just one thing I think of it's like

1874
01:15:01,680 --> 01:15:00,010
a lot of precious earth metals which

1875
01:15:03,780 --> 01:15:01,690
really aren't earth metals they came in

1876
01:15:05,729 --> 01:15:03,790
asteroids and they're like formed in the

1877
01:15:07,979 --> 01:15:05,739
solar system and impacted and hit earth

1878
01:15:09,930 --> 01:15:07,989
but I mean there's a lot of craters on

1879
01:15:12,630 --> 01:15:09,940
the moon there could be a chance that

1880
01:15:15,870 --> 01:15:12,640
there's precious earth metals or moon or

1881
01:15:17,880 --> 01:15:15,880
asteroid really profitable together yeah

1882
01:15:20,669 --> 01:15:17,890
the thing about metals and asteroids is

1883
01:15:22,590 --> 01:15:20,679
that on the earth you have metals that

1884
01:15:24,450 --> 01:15:22,600
love to dissolve an iron and then they

1885
01:15:26,300 --> 01:15:24,460
just sink to the core so all our gold

1886
01:15:29,729 --> 01:15:26,310
and platinum is all in the core

1887
01:15:31,590 --> 01:15:29,739
whereas on asteroids well they're there

1888
01:15:33,450 --> 01:15:31,600
all the planets apart and we can

1889
01:15:35,430 --> 01:15:33,460
actually get bits of the cores of

1890
01:15:37,680 --> 01:15:35,440
crucial planets that's why asteroid

1891
01:15:40,260 --> 01:15:37,690
mining has these bits of metal these

1892
01:15:41,400 --> 01:15:40,270
huge amounts of metal in them so I see

1893
01:15:43,620 --> 01:15:41,410
that we're getting a little bit closer

1894
01:15:44,970 --> 01:15:43,630
on on Kerbal but there was a question

1895
01:15:46,620 --> 01:15:44,980
that came in for Scott it was like could

1896
01:15:50,209 --> 01:15:46,630
you please ask Scott about the KSP

1897
01:15:53,189 --> 01:15:50,219
Kraken the Kraken yes the Kraken is a

1898
01:15:57,209 --> 01:15:53,199
fantastic result of game rolling yes

1899
01:15:59,310 --> 01:15:57,219
so the Kraken is what happens when

1900
01:16:02,959 --> 01:15:59,320
physics goes wrong

1901
01:16:06,359 --> 01:16:02,969
okay it's it's kind of fascinating

1902
01:16:08,040 --> 01:16:06,369
sometimes there's a physics engine in

1903
01:16:10,080 --> 01:16:08,050
the game that's modeling how it works

1904
01:16:13,379 --> 01:16:10,090
how the physics and everything works and

1905
01:16:15,450 --> 01:16:13,389
sometimes it has mathematical errors

1906
01:16:17,669 --> 01:16:15,460
which can cause the spacecraft to

1907
01:16:19,919 --> 01:16:17,679
disintegrate so in the old days when you

1908
01:16:21,450 --> 01:16:19,929
got very very fast and very very close

1909
01:16:23,220 --> 01:16:21,460
to the Sun the spacecraft would just

1910
01:16:26,399 --> 01:16:23,230
spin out of control and disintegrate and

1911
01:16:28,140 --> 01:16:26,409
we called that the Kraken and you the

1912
01:16:30,209 --> 01:16:28,150
developers have slowly fixed these

1913
01:16:32,459 --> 01:16:30,219
things bit by bit but every now and then

1914
01:16:34,350 --> 01:16:32,469
you will just find the most bizarre bug

1915
01:16:37,319 --> 01:16:34,360
where your spacecraft just spontaneously

1916
01:16:39,359 --> 01:16:37,329
explodes or you know you hit some weird

1917
01:16:41,700 --> 01:16:39,369
singularity in the mathematics and

1918
01:16:43,169 --> 01:16:41,710
everything disintegrates and and then

1919
01:16:44,939 --> 01:16:43,179
people have learned to harness the

1920
01:16:47,640 --> 01:16:44,949
kraken for good and they've learned to

1921
01:16:50,609 --> 01:16:47,650
build kraken drives reaction 'less

1922
01:16:53,250 --> 01:16:50,619
thrusters that don't need fuel so yeah

1923
01:16:55,680 --> 01:16:53,260
the kraken is a great friend and enemy

1924
01:16:57,780 --> 01:16:55,690
in the game and is actually out on one

1925
01:17:00,300 --> 01:16:57,790
of the moons there's a kraken corpse

1926
01:17:03,149 --> 01:17:00,310
available that you can find if you're

1927
01:17:05,010 --> 01:17:03,159
you're sufficiently interested so

1928
01:17:06,300 --> 01:17:05,020
there's another thing from the chat

1929
01:17:08,819 --> 01:17:06,310
another question this is from Fox

1930
01:17:10,470 --> 01:17:08,829
underscore tango which like welcome back

1931
01:17:13,080 --> 01:17:10,480
I remember Fox tango has been there

1932
01:17:16,979 --> 01:17:13,090
quite a bit so in previous episodes but

1933
01:17:18,750 --> 01:17:16,989
have any samples physio electric stone

1934
01:17:22,319 --> 01:17:18,760
been collected from the moon Mars or

1935
01:17:24,600 --> 01:17:22,329
other astral body okay I'm probably

1936
01:17:27,350 --> 01:17:24,610
butchering the name people are looking

1937
01:17:29,250 --> 01:17:27,360
at me and shaking their heads the

1938
01:17:31,740 --> 01:17:29,260
materials that came back from from the

1939
01:17:34,069 --> 01:17:31,750
moon that have been analyzed

1940
01:17:36,479 --> 01:17:34,079
I don't recall them having any

1941
01:17:38,010 --> 01:17:36,489
piezoelectric or semiconductor

1942
01:17:40,080 --> 01:17:38,020
properties but I'm not a material

1943
01:17:41,520 --> 01:17:40,090
scientist so I could be a fizzy electric

1944
01:17:43,800 --> 01:17:41,530
the word that I'd butchered what is that

1945
01:17:49,550 --> 01:17:43,810
so if you have a material that you

1946
01:17:50,729 --> 01:17:49,560
impose stress on it produces voltage

1947
01:17:52,740 --> 01:17:50,739
okay

1948
01:17:54,750 --> 01:17:52,750
right and vice-versa so you can apply

1949
01:17:57,240 --> 01:17:54,760
voltage and it'll displace the material

1950
01:17:58,589 --> 01:17:57,250
so like the it's like metal for example

1951
01:18:00,510 --> 01:17:58,599
it's some of the materials in your

1952
01:18:02,280 --> 01:18:00,520
microphone my admite might be a

1953
01:18:04,680 --> 01:18:02,290
piezoelectric microphone certainly the

1954
01:18:07,350 --> 01:18:04,690
probably the one in your phone is yeah

1955
01:18:11,040 --> 01:18:07,360
right so it's converting the pressure

1956
01:18:11,700 --> 01:18:11,050
from the sound waves in your voice into

1957
01:18:15,540 --> 01:18:11,710
electric

1958
01:18:17,700 --> 01:18:15,550
signal materials materials that do that

1959
01:18:22,350 --> 01:18:17,710
right a family of those materials is

1960
01:18:25,290 --> 01:18:22,360
it's a piezoelectric effect the more you

1961
01:18:30,060 --> 01:18:25,300
know so the short version the short

1962
01:18:32,640 --> 01:18:30,070
answer to their question yes no we don't

1963
01:18:35,640 --> 01:18:32,650
know we don't know we don't recall any

1964
01:18:38,340 --> 01:18:35,650
of that coming in but that doesn't mean

1965
01:18:41,459 --> 01:18:38,350
it hasn't yeah they're very easy to make

1966
01:18:43,140 --> 01:18:41,469
I mean they're they're pretty much very

1967
01:18:45,300 --> 01:18:43,150
simple industrial I mean they're types

1968
01:18:47,850 --> 01:18:45,310
of corpse what's doping yeah it's

1969
01:18:50,370 --> 01:18:47,860
everywhere so so alright are we are we

1970
01:18:57,300 --> 01:18:50,380
at the moon or real and another but Oh

1971
01:18:59,250 --> 01:18:57,310
apparently we know one use sticky keys I

1972
01:19:00,900 --> 01:18:59,260
was trying to rendezvous but it's

1973
01:19:02,750 --> 01:19:00,910
actually very hard because there you

1974
01:19:06,150 --> 01:19:02,760
have to minimize big picture mode

1975
01:19:07,860 --> 01:19:06,160
minimize big picture yeah okay my

1976
01:19:09,930 --> 01:19:07,870
desktop it's a good thing I wasn't

1977
01:19:11,459 --> 01:19:09,940
trying to land at that time I can't tell

1978
01:19:15,540 --> 01:19:11,469
ladies and gentlemen this is not Scott's

1979
01:19:17,940 --> 01:19:15,550
normal PC I'm actually having some

1980
01:19:20,370 --> 01:19:17,950
interesting problems here because I have

1981
01:19:23,250 --> 01:19:20,380
I can't see the orbit as easily as I

1982
01:19:25,020 --> 01:19:23,260
normally would I think yeah I'm just

1983
01:19:28,170 --> 01:19:25,030
trying to make figure out how to make

1984
01:19:30,540 --> 01:19:28,180
this rendezvous here but you go on yeah

1985
01:19:33,450 --> 01:19:30,550
so well there is somebody there's a

1986
01:19:36,720 --> 01:19:33,460
Hazen canet 42 was saying do a suicide

1987
01:19:38,310 --> 01:19:36,730
burn landing on the moon please okay but

1988
01:19:40,350 --> 01:19:38,320
never right let's just try landing this

1989
01:19:44,270 --> 01:19:40,360
everybody wants to see me try a landing

1990
01:19:46,920 --> 01:19:44,280
right why so move to another another

1991
01:19:49,470 --> 01:19:46,930
question from alpha King gore

1992
01:19:52,080 --> 01:19:49,480
how big how big a problem is space

1993
01:19:54,690 --> 01:19:52,090
debris is there that up to everybody for

1994
01:19:57,450 --> 01:19:54,700
what you think well it's a at the moment

1995
01:20:00,540 --> 01:19:57,460
it's a pretty problem but it's not a

1996
01:20:02,970 --> 01:20:00,550
gigantic problem right now it's in the

1997
01:20:04,260 --> 01:20:02,980
news frequently these days because it

1998
01:20:06,780 --> 01:20:04,270
has the potential to become a huge

1999
01:20:08,729 --> 01:20:06,790
problem alright so right now there's

2000
01:20:10,920 --> 01:20:08,739
plenty of space debris up there there's

2001
01:20:13,680 --> 01:20:10,930
spent rocket bodies there's dead

2002
01:20:15,870 --> 01:20:13,690
satellites there's little bits of nuts

2003
01:20:18,090 --> 01:20:15,880
and bolts and junk that's blown up over

2004
01:20:20,850 --> 01:20:18,100
the years there's a whole big cloud of

2005
01:20:24,430 --> 01:20:20,860
debris from satellites that have

2006
01:20:28,320 --> 01:20:24,440
collided the good news is

2007
01:20:30,610 --> 01:20:28,330
most of it is not where we have people

2008
01:20:34,990 --> 01:20:30,620
right for example on the space station

2009
01:20:37,660 --> 01:20:35,000
and most of it is not where it's gonna

2010
01:20:39,490 --> 01:20:37,670
run into other satellites at the moment

2011
01:20:41,170 --> 01:20:39,500
right we do occasionally have to move

2012
01:20:45,150 --> 01:20:41,180
satellites to get out of the way of

2013
01:20:48,280 --> 01:20:45,160
space debris as it's floating around

2014
01:20:49,720 --> 01:20:48,290
however right with all the spacecraft

2015
01:20:51,100 --> 01:20:49,730
that are being launched and there's more

2016
01:20:54,580 --> 01:20:51,110
and more spacecraft being launched all

2017
01:20:58,060 --> 01:20:54,590
the time all it would take is a couple

2018
01:21:01,630 --> 01:20:58,070
of bad days ok they're suddenly to be a

2019
01:21:04,720 --> 01:21:01,640
whole lot of space debris in a bad place

2020
01:21:07,030 --> 01:21:04,730
right so the potential for there to be a

2021
01:21:10,689 --> 01:21:07,040
really big space debris problem is very

2022
01:21:12,640 --> 01:21:10,699
high so let me jump into one more are we

2023
01:21:14,800 --> 01:21:12,650
ready to land are we get in there well

2024
01:21:16,920 --> 01:21:14,810
we're gonna I got a fun Mars one and I

2025
01:21:20,020 --> 01:21:16,930
know Marybeth Mars is her favorite

2026
01:21:21,910 --> 01:21:20,030
subjects a Martian yes she's very much

2027
01:21:24,280 --> 01:21:21,920
the Martian if folks didn't know that

2028
01:21:25,600 --> 01:21:24,290
the you you co-authored the paper for

2029
01:21:28,209 --> 01:21:25,610
when they discovered liquid water on

2030
01:21:36,400 --> 01:21:28,219
Mars you know whatever just kind of

2031
01:21:40,330 --> 01:21:36,410
dusted on you know but okay here's a

2032
01:21:43,750 --> 01:21:40,340
question from Jared on who's asking what

2033
01:21:47,080 --> 01:21:43,760
to do about perchloric chloride on Mars

2034
01:21:49,900 --> 01:21:47,090
when crews for correctly when crews

2035
01:21:51,820 --> 01:21:49,910
visit when crews yep so perchlorate as a

2036
01:21:54,340 --> 01:21:51,830
salt and it's not on earth that actually

2037
01:21:56,500 --> 01:21:54,350
comprises rocket fuel too and it

2038
01:21:58,240 --> 01:21:56,510
accumulates an extremely dry places so

2039
01:22:00,130 --> 01:21:58,250
it's a it's a problem in a lot of desert

2040
01:22:03,220 --> 01:22:00,140
environments including in Southern

2041
01:22:06,670 --> 01:22:03,230
California for example and it's toxic to

2042
01:22:08,650 --> 01:22:06,680
humans so if you consume perchlorate

2043
01:22:10,810 --> 01:22:08,660
because it's so soluble meaning it like

2044
01:22:13,180 --> 01:22:10,820
goes into water very easily and you

2045
01:22:15,189 --> 01:22:13,190
drink that water it can cost I roid

2046
01:22:18,220 --> 01:22:15,199
issues and actually I think it used to

2047
01:22:21,340 --> 01:22:18,230
be used as a treatment for overactive

2048
01:22:23,080 --> 01:22:21,350
thyroid like back in the day anyway so

2049
01:22:25,420 --> 01:22:23,090
Pirkle there's a ton of perchlorate on

2050
01:22:27,850 --> 01:22:25,430
Mars and that ties into the whole water

2051
01:22:30,760 --> 01:22:27,860
on Mars story because what we detected

2052
01:22:33,790 --> 01:22:30,770
was actually hydrated perchlorates

2053
01:22:35,919 --> 01:22:33,800
so water banned sat or water within the

2054
01:22:37,870 --> 01:22:35,929
mineral structure of perchlorates so

2055
01:22:40,270 --> 01:22:37,880
anyway yeah if we if we

2056
01:22:43,660 --> 01:22:40,280
using any resources there on Mars

2057
01:22:48,250 --> 01:22:43,670
someday perchlorate remediation might be

2058
01:22:49,689 --> 01:22:48,260
an issue depending on you know how how

2059
01:22:51,310 --> 01:22:49,699
and what we use that type of water for

2060
01:22:53,560 --> 01:22:51,320
it's a mark watney's gonna have a hard

2061
01:22:58,840 --> 01:22:53,570
time growing his potatoes well he might

2062
01:23:01,629 --> 01:22:58,850
have a hard time having a thyroid there

2063
01:23:05,020 --> 01:23:01,639
are chemical solutions to this and I'm

2064
01:23:06,760 --> 01:23:05,030
sure we could figure out a way to to

2065
01:23:09,490 --> 01:23:06,770
remove it if we need it to but it also

2066
01:23:11,229 --> 01:23:09,500
gets in the way just from a science

2067
01:23:13,870 --> 01:23:11,239
perspective when we're doing analyses of

2068
01:23:15,939 --> 01:23:13,880
the soils it can actually react with

2069
01:23:18,850 --> 01:23:15,949
some of the the organic the carbon

2070
01:23:20,620 --> 01:23:18,860
bearing compounds in the soil and turn

2071
01:23:24,669 --> 01:23:20,630
into a big chemistry reaction so it's

2072
01:23:26,500 --> 01:23:24,679
been problematic for for previous Mars

2073
01:23:29,410 --> 01:23:26,510
missions looking for organic compounds

2074
01:23:31,000 --> 01:23:29,420
so so as we're looking on the screen

2075
01:23:34,570 --> 01:23:31,010
right now what do you have going for us

2076
01:23:37,030 --> 01:23:34,580
I think we decided to break with the

2077
01:23:39,490 --> 01:23:37,040
actual mission plan yeah we're just

2078
01:23:41,620 --> 01:23:39,500
gonna land we're gonna lend this using

2079
01:23:43,209 --> 01:23:41,630
its we just left all that extra fuel out

2080
01:23:45,910 --> 01:23:43,219
there we figure you know what let's just

2081
01:23:47,740 --> 01:23:45,920
jump well you know I should we finally

2082
01:23:50,590 --> 01:23:47,750
depleted that big tank so I think I'm

2083
01:23:52,750 --> 01:23:50,600
gonna aim between these creatures here

2084
01:23:54,910 --> 01:23:52,760
so this little version of the Orion is

2085
01:23:56,740 --> 01:23:54,920
this have some landing gear no no we're

2086
01:23:59,620 --> 01:23:56,750
just gonna land on the engine hills yeah

2087
01:24:01,419 --> 01:23:59,630
just checking just yeah we just solar

2088
01:24:04,260 --> 01:24:01,429
panels we should probably open those up

2089
01:24:07,030 --> 01:24:04,270
just so we can get some electrical power

2090
01:24:08,770 --> 01:24:07,040
nice it just could be more thrust or no

2091
01:24:10,149 --> 01:24:08,780
just we don't want to run out of

2092
01:24:12,490 --> 01:24:10,159
electrical power when we're trying to

2093
01:24:14,560 --> 01:24:12,500
land do we I think that would be bad

2094
01:24:16,149 --> 01:24:14,570
yeah so we're just gonna put it down

2095
01:24:18,669 --> 01:24:16,159
between these craters and hopefully we

2096
01:24:20,169 --> 01:24:18,679
won't fall over yeah this is a standard

2097
01:24:22,060 --> 01:24:20,179
Kerbal maneuver landing on the engine

2098
01:24:23,890 --> 01:24:22,070
bells do not do it in a real rocket

2099
01:24:25,870 --> 01:24:23,900
because engine bells Tanner

2100
01:24:28,090 --> 01:24:25,880
yeah well crush them you will crush them

2101
01:24:29,890 --> 01:24:28,100
yeah even on one of the Apollo missions

2102
01:24:32,350 --> 01:24:29,900
they came down too close to the surface

2103
01:24:34,330 --> 01:24:32,360
and the engine bail got sort of crushed

2104
01:24:37,300 --> 01:24:34,340
just by the force of the rocket exhaust

2105
01:24:39,430 --> 01:24:37,310
there's a famous photo of it being earth

2106
01:24:40,840 --> 01:24:39,440
with a fold in it and that wasn't

2107
01:24:43,090 --> 01:24:40,850
because it hit the surface it's just

2108
01:24:45,700 --> 01:24:43,100
because the rocket exhaust bounced off

2109
01:24:47,320 --> 01:24:45,710
and came back like a sound wave I'd like

2110
01:24:50,330 --> 01:24:47,330
to point out that the solar arrays are a

2111
01:24:56,580 --> 01:24:50,340
little dinky they are

2112
01:24:58,770 --> 01:24:56,590
we're very efficient I know one thing

2113
01:25:01,350 --> 01:24:58,780
I'm not sure off here is I can't see I

2114
01:25:09,050 --> 01:25:01,360
don't have an altitude meter there we go

2115
01:25:13,290 --> 01:25:09,060
there you approach yes here we go oh

2116
01:25:17,280 --> 01:25:13,300
good okay yes we did it and we can all

2117
01:25:18,480 --> 01:25:17,290
evie a I'll just get you off there oh

2118
01:25:20,280 --> 01:25:18,490
look at that

2119
01:25:21,870 --> 01:25:20,290
shut yeah we just wanted to go to the

2120
01:25:24,690 --> 01:25:21,880
moon yep you're on the moon and we're

2121
01:25:26,850 --> 01:25:24,700
just gonna let you use the cheese though

2122
01:25:28,410 --> 01:25:26,860
as we learn from the first episode that

2123
01:25:29,910 --> 01:25:28,420
we did about four weeks ago with the

2124
01:25:31,080 --> 01:25:29,920
administrator Jim Brian Sam we learned

2125
01:25:37,070 --> 01:25:31,090
that the moon was made of spare wet

2126
01:25:44,550 --> 01:25:40,440
for commercial use I'm sure the moon has

2127
01:25:49,380 --> 01:25:44,560
meaning great but I don't think Jesus

2128
01:25:51,240 --> 01:25:49,390
parents a veritable cornucopia it's

2129
01:25:53,940 --> 01:25:51,250
harder to prove that the moon isn't made

2130
01:25:56,850 --> 01:25:53,950
of cheese than it is to prove or the

2131
01:25:59,880 --> 01:25:56,860
earth isn't flat nice so why isn't a

2132
01:26:02,790 --> 01:25:59,890
mushi Society no boon to society exactly

2133
01:26:04,650 --> 01:26:02,800
there is and they could be raining every

2134
01:26:07,490 --> 01:26:04,660
single twitch stream every single NASA

2135
01:26:11,100 --> 01:26:07,500
stream or social media platform with the

2136
01:26:14,250 --> 01:26:11,110
moon cheese or like truthers we should

2137
01:26:17,700 --> 01:26:14,260
plant a flag here there I claim this

2138
01:26:20,760 --> 01:26:17,710
moon in the name of we got to come up

2139
01:26:23,820 --> 01:26:20,770
with a message for all humanity yes yes

2140
01:26:27,660 --> 01:26:23,830
I think that's yours yeah what are you

2141
01:26:29,520 --> 01:26:27,670
gonna tell the world what are you

2142
01:26:30,510 --> 01:26:29,530
looking for what's the first thing you

2143
01:26:33,330 --> 01:26:30,520
do you've landed on the moon

2144
01:26:35,970 --> 01:26:33,340
I got a quote Pete Conrad okay that may

2145
01:26:41,610 --> 01:26:35,980
have been one small step for uh but that

2146
01:26:43,200 --> 01:26:41,620
was one long one for me yes nice we're

2147
01:26:45,930 --> 01:26:43,210
counting down to about like two minutes

2148
01:26:47,780 --> 01:26:45,940
until we wrap up so I'm wondering we

2149
01:26:50,760 --> 01:26:47,790
could fight you another rapid-fire one

2150
01:26:52,260 --> 01:26:50,770
we have some okay if bigger rockets

2151
01:26:54,180 --> 01:26:52,270
increase efficiency for launching

2152
01:26:56,370 --> 01:26:54,190
experiments why don't we launch even

2153
01:26:58,680 --> 01:26:56,380
bigger rockets this is asked by Frank a

2154
01:27:01,230 --> 01:26:58,690
fifth grader in red from resonator games

2155
01:27:02,549 --> 01:27:01,240
because building bigger rocket engines

2156
01:27:05,040 --> 01:27:02,559
is actually harder

2157
01:27:06,719 --> 01:27:05,050
you imagine that's why the fYI engines

2158
01:27:08,489 --> 01:27:06,729
are probably the biggest rocket engines

2159
01:27:12,000 --> 01:27:08,499
I've ever been built due to combustion

2160
01:27:14,250 --> 01:27:12,010
instability and things like that yeah I

2161
01:27:16,379 --> 01:27:14,260
would I don't know that building bigger

2162
01:27:19,829 --> 01:27:16,389
necessarily buys you more efficiency

2163
01:27:22,290 --> 01:27:19,839
right in the case of SLS it's bigger

2164
01:27:24,089 --> 01:27:22,300
because we've got some pretty big

2165
01:27:27,750 --> 01:27:24,099
massive stuff that we want to send

2166
01:27:30,059 --> 01:27:27,760
fairly far out beyond Earth orbit at the

2167
01:27:31,619 --> 01:27:30,069
same time NASA's building the big SLS we

2168
01:27:33,509 --> 01:27:31,629
have a bunch of commercial companies

2169
01:27:35,939 --> 01:27:33,519
that are building really small launch

2170
01:27:38,729 --> 01:27:35,949
vehicles to send really small things

2171
01:27:40,229 --> 01:27:38,739
into Earth orbit and so we're looking

2172
01:27:42,000 --> 01:27:40,239
forward to the day when we're just

2173
01:27:43,829 --> 01:27:42,010
sending little little tiny things up on

2174
01:27:45,959 --> 01:27:43,839
little tiny Rockets all the time

2175
01:27:48,989 --> 01:27:45,969
but they're those Rockets aren't going

2176
01:27:50,609 --> 01:27:48,999
to be sending things out to the moon so

2177
01:27:52,259 --> 01:27:50,619
there's a there's a happy mix of the

2178
01:27:54,809 --> 01:27:52,269
great big Rockets to send big things

2179
01:27:56,669 --> 01:27:54,819
really far out and little tiny Rockets

2180
01:28:00,209 --> 01:27:56,679
sending little tiny things into the

2181
01:28:03,509 --> 01:28:00,219
vicinity of the earth so that folks is

2182
01:28:06,149 --> 01:28:03,519
about all the time that we have as you

2183
01:28:07,679 --> 01:28:06,159
can look from behind us Chad and

2184
01:28:12,149 --> 01:28:07,689
Marybeth are going to continue their Eve

2185
01:28:13,529 --> 01:28:12,159
EA out on the moon so hey this is a

2186
01:28:15,509 --> 01:28:13,539
reminder this has been NASA in Silicon

2187
01:28:17,579 --> 01:28:15,519
Valley live is a conversational show

2188
01:28:19,020 --> 01:28:17,589
where we talk to proud of the Ames

2189
01:28:21,029 --> 01:28:19,030
Research Center where we talked to the

2190
01:28:24,329 --> 01:28:21,039
scientists researchers engineers and

2191
01:28:26,790 --> 01:28:24,339
overall cool people here at NASA if you

2192
01:28:29,250 --> 01:28:26,800
like that then we are live on twitch on

2193
01:28:31,049 --> 01:28:29,260

and it'll also be up on NASA TV as a

2200
01:28:44,369 --> 01:28:42,519
rebroadcast I think about next week

2201
01:28:46,349 --> 01:28:44,379
