1
00:00:00,000 --> 00:00:04,320
Imagine being a student and getting to send something you built into space.

2
00:00:04,320 --> 00:00:05,320
Wow!

3
00:00:05,320 --> 00:00:07,640
That's the incredible opportunity CubeSats are creating.

4
00:00:07,640 --> 00:00:08,640
It really is.

5
00:00:08,640 --> 00:00:11,680
They're these tiny satellites about the size of a loaf of bread.

6
00:00:11,680 --> 00:00:12,680
Yeah!

7
00:00:12,680 --> 00:00:17,320
Making waves in astronomy and opening doors that were once only a dream.

8
00:00:17,320 --> 00:00:18,320
Yeah!

9
00:00:18,320 --> 00:00:21,480
Welcome to Cosmos Centipods Space and Astronomy series.

10
00:00:21,480 --> 00:00:22,480
Yeah.

11
00:00:22,480 --> 00:00:25,080
Today we're diving deep into the world of CubeSats.

12
00:00:25,080 --> 00:00:26,080
Sounds exciting.

13
00:00:26,080 --> 00:00:28,240
Okay, so you've piqued my curiosity.

14
00:00:28,240 --> 00:00:29,240
Right.

15
00:00:29,240 --> 00:00:32,520
What exactly are CubeSats and how do they become so impactful?

16
00:00:32,520 --> 00:00:35,440
Well, CubeSats revolutionize space exploration.

17
00:00:35,440 --> 00:00:36,440
Okay.

18
00:00:36,440 --> 00:00:37,440
By making it more accessible.

19
00:00:37,440 --> 00:00:38,440
Okay.

20
00:00:38,440 --> 00:00:43,040
Imagine a standardized 10 by 10 by 10 centimeter cube.

21
00:00:43,040 --> 00:00:44,880
That's your basic building block.

22
00:00:44,880 --> 00:00:49,200
Each one weighs just a bit over a kilogram and you can combine them like Legos.

23
00:00:49,200 --> 00:00:50,200
Oh, wow!

24
00:00:50,200 --> 00:00:52,560
To create larger, more complex satellites.

25
00:00:52,560 --> 00:00:53,560
Interesting.

26
00:00:53,560 --> 00:00:57,880
This modular design coupled with off-the-shelf components makes them significantly more affordable

27
00:00:57,880 --> 00:00:59,720
to build than traditional satellites.

28
00:00:59,720 --> 00:01:01,840
So it's like a DIY kit for space exploration.

29
00:01:01,840 --> 00:01:02,840
Exactly.

30
00:01:02,840 --> 00:01:03,840
But how much cheaper are you talking?

31
00:01:03,840 --> 00:01:04,840
Give me some numbers.

32
00:01:04,840 --> 00:01:06,940
It's dramatically cheaper.

33
00:01:06,940 --> 00:01:10,520
We're talking about launching a mission for a few hundred thousand dollars instead of

34
00:01:10,520 --> 00:01:11,520
hundreds of millions.

35
00:01:11,520 --> 00:01:12,520
Wow, that's incredible.

36
00:01:12,520 --> 00:01:13,760
Think about it.

37
00:01:13,760 --> 00:01:18,840
Missions that were once only possible for large government agencies are now within reach

38
00:01:18,840 --> 00:01:23,600
of universities, small businesses, and even individual researchers.

39
00:01:23,600 --> 00:01:25,000
That's a game changer for sure.

40
00:01:25,000 --> 00:01:26,000
Yeah.

41
00:01:26,000 --> 00:01:30,920
It's a playing field and allows for more diverse perspectives and research opportunities.

42
00:01:30,920 --> 00:01:33,000
But cost isn't the only advantage.

43
00:01:33,000 --> 00:01:34,000
Right.

44
00:01:34,000 --> 00:01:35,800
What else makes CubeSat so special?

45
00:01:35,800 --> 00:01:38,840
The speed of development is another major factor.

46
00:01:38,840 --> 00:01:43,240
Building and launching a CubeSat can be done in a matter of months, not years, like traditional

47
00:01:43,240 --> 00:01:44,240
missions.

48
00:01:44,240 --> 00:01:45,240
Oh, wow.

49
00:01:45,240 --> 00:01:51,840
This rapid turnaround is perfect for responding to time-sensitive events like supernova explosions

50
00:01:51,840 --> 00:01:54,840
or studying rapidly changing phenomena.

51
00:01:54,840 --> 00:02:01,680
Plus, CubeSats can often hitch a ride on larger rockets as secondary payloads, further reducing

52
00:02:01,680 --> 00:02:04,360
launch costs and simplifying the process.

53
00:02:04,360 --> 00:02:08,800
Okay, so they're cheaper, faster to develop, and can piggyback on other launches.

54
00:02:08,800 --> 00:02:12,820
But are they limited by their size in terms of what they can actually do in space?

55
00:02:12,820 --> 00:02:14,880
Not as much as you might think.

56
00:02:14,880 --> 00:02:20,320
Despite their small size, CubeSats can be equipped with surprisingly sophisticated instruments.

57
00:02:20,320 --> 00:02:21,320
Okay.

58
00:02:21,320 --> 00:02:23,320
Miniaturized cameras, spectrometers, sensors.

59
00:02:23,320 --> 00:02:24,320
Wow.

60
00:02:24,320 --> 00:02:26,720
And capable of performing various tasks.

61
00:02:26,720 --> 00:02:27,720
Yeah.

62
00:02:27,720 --> 00:02:32,440
From imaging celestial objects to collecting data on radiation and magnetic fields.

63
00:02:32,440 --> 00:02:34,560
It's like having a Swiss Army knife in space.

64
00:02:34,560 --> 00:02:36,000
Wow, that's impressive.

65
00:02:36,000 --> 00:02:40,520
So what kind of research are these tiny powerhouses enabling in astronomy?

66
00:02:40,520 --> 00:02:44,160
One area where CubeSats are making a big impact is the study of exoplanets.

67
00:02:44,160 --> 00:02:45,440
Oh, cool.

68
00:02:45,440 --> 00:02:50,000
You see a mission called Asteria, which was about the size of a briefcase, demonstrated

69
00:02:50,000 --> 00:02:52,800
that these little satellites can detect exoplanets.

70
00:02:52,800 --> 00:02:53,800
Wow.

71
00:02:53,800 --> 00:02:56,880
They're using a technique called precision photometry.

72
00:02:56,880 --> 00:03:01,120
It essentially measures the tiny dips in a star's light that occur when a planet passes

73
00:03:01,120 --> 00:03:02,120
in front of it.

74
00:03:02,120 --> 00:03:03,120
Okay.

75
00:03:03,120 --> 00:03:08,000
But detecting those tiny dips in starlight must require incredibly sensitive instruments.

76
00:03:08,000 --> 00:03:09,000
Right.

77
00:03:09,000 --> 00:03:12,200
How can they achieve that level of precision in such a small package?

78
00:03:12,200 --> 00:03:16,200
That's the remarkable thing about CubeSats and the advancements in miniaturization.

79
00:03:16,200 --> 00:03:21,800
Asteria, for instance, used a highly stable telescope, an advanced software, to achieve

80
00:03:21,800 --> 00:03:26,160
the precision needed to detect those subtle changes in starlight.

81
00:03:26,160 --> 00:03:31,840
So we're talking about finding planets orbiting other stars with a satellite the size of a

82
00:03:31,840 --> 00:03:32,840
briefcase.

83
00:03:32,840 --> 00:03:33,840
Exactly.

84
00:03:33,840 --> 00:03:36,720
What other amazing feats are these CubeSats capable of?

85
00:03:36,720 --> 00:03:41,520
Well, their agility makes them ideal for studying transient events, those sudden fleeting phenomena

86
00:03:41,520 --> 00:03:43,160
in the universe.

87
00:03:43,160 --> 00:03:45,960
Think about gamma ray bursts or supernovae.

88
00:03:45,960 --> 00:03:46,960
Got it.

89
00:03:46,960 --> 00:03:50,840
KickSats can be deployed quickly to capture these events in real time.

90
00:03:50,840 --> 00:03:54,400
Something larger, less maneuverable telescopes often struggle with.

91
00:03:54,400 --> 00:03:57,360
It's like having a rapid response team for cosmic events.

92
00:03:57,360 --> 00:04:01,320
So we're talking about cosmic paparazzi, always ready to capture the celestial action

93
00:04:01,320 --> 00:04:02,320
as it unfolds.

94
00:04:02,320 --> 00:04:03,320
Exactly.

95
00:04:03,320 --> 00:04:08,200
And let's not forget our own store, the Sun, dedicated CubeSats like QC, the CubeSat for

96
00:04:08,200 --> 00:04:12,640
solar particles, are helping us understand solar activity and space weather, which can

97
00:04:12,640 --> 00:04:17,240
impact satellites, communication systems, and even power grids here on Earth.

98
00:04:17,240 --> 00:04:18,240
Okay.

99
00:04:18,240 --> 00:04:20,080
Now that's something we should all be paying attention to.

100
00:04:20,080 --> 00:04:21,080
Right.

101
00:04:21,080 --> 00:04:23,120
Space weather can have real world consequences.

102
00:04:23,120 --> 00:04:27,240
So having a fleet of CubeSats monitoring the Sun is definitely a good idea.

103
00:04:27,240 --> 00:04:28,240
Absolutely.

104
00:04:28,240 --> 00:04:33,200
It provides us with valuable data that helps us predict and prepare for potential disruptions.

105
00:04:33,200 --> 00:04:36,520
And the applications go beyond our immediate neighborhood.

106
00:04:36,520 --> 00:04:41,040
Imagine CubeSats mapping distant galaxies studying dark matter and even probing the

107
00:04:41,040 --> 00:04:43,960
cosmic microwave background radiation.

108
00:04:43,960 --> 00:04:48,880
It's mind blowing to think that something so small can contribute so much to our understanding

109
00:04:48,880 --> 00:04:50,960
of something so vast.

110
00:04:50,960 --> 00:04:55,600
It really challenges our perception of what's possible in space exploration.

111
00:04:55,600 --> 00:04:59,440
Are there any particular CubeSat missions that stand out as signing examples of their

112
00:04:59,440 --> 00:05:00,440
capabilities?

113
00:05:00,440 --> 00:05:01,440
Oh, definitely.

114
00:05:01,440 --> 00:05:03,120
There's MARCO, the Mars Cube-1.

115
00:05:03,120 --> 00:05:07,220
This dynamic duo of CubeSats made history by hitching a ride on NASA's InSight mission

116
00:05:07,220 --> 00:05:09,080
to Mars in 2018.

117
00:05:09,080 --> 00:05:13,980
They became the first CubeSats to venture into interplanetary space, relaying crucial

118
00:05:13,980 --> 00:05:17,040
data during InSight's descent and landing on the red planet.

119
00:05:17,040 --> 00:05:19,080
Wait, CubeSats went to Mars?

120
00:05:19,080 --> 00:05:21,480
That's a giant leap for tiny satellites.

121
00:05:21,480 --> 00:05:23,640
What other groundbreaking missions should we know about?

122
00:05:23,640 --> 00:05:27,960
Well, besides Asterio, which we discussed earlier, there's HaloSat.

123
00:05:27,960 --> 00:05:32,840
This mission focused on mapping the hot gas halo surrounding our Milky Way galaxy.

124
00:05:32,840 --> 00:05:36,960
This halo, which extends hundreds of thousands of light years beyond the visible disk of

125
00:05:36,960 --> 00:05:41,440
our galaxy, is thought to hold secrets about how galaxies form and evolve.

126
00:05:41,440 --> 00:05:45,440
So HaloSat is helping us unravel the mysteries of galactic evolution.

127
00:05:45,440 --> 00:05:46,440
That's incredible.

128
00:05:46,440 --> 00:05:48,520
So the missions are out there pushing the boundaries.

129
00:05:48,520 --> 00:05:53,120
There's HUT-U, the CubeSat UV experiment, which studies the atmospheres of exoplanets

130
00:05:53,120 --> 00:05:58,160
to better understand their habitability and capstone, which is testing navigation systems

131
00:05:58,160 --> 00:06:02,360
in a special lunar orbit, paving the way for the Artemis program to return humans to the

132
00:06:02,360 --> 00:06:03,360
moon.

133
00:06:03,360 --> 00:06:07,600
It sounds like CubeSats are playing a crucial role in almost every aspect of space exploration.

134
00:06:07,600 --> 00:06:08,960
They really are.

135
00:06:08,960 --> 00:06:11,840
But their contribution goes beyond individual missions.

136
00:06:11,840 --> 00:06:16,760
They often complement larger missions, filling in data gaps, providing continuous monitoring,

137
00:06:16,760 --> 00:06:21,040
and even acting as test beds for new technologies before they're integrated into larger, more

138
00:06:21,040 --> 00:06:22,480
expensive spacecraft.

139
00:06:22,480 --> 00:06:27,700
So they're like the unsung heroes of space exploration, quietly working behind the scenes

140
00:06:27,700 --> 00:06:30,520
to advance our understanding of the universe.

141
00:06:30,520 --> 00:06:31,720
Exactly.

142
00:06:31,720 --> 00:06:37,280
Imagine swarms of CubeSats acting as distributed observatories, capturing data from multiple

143
00:06:37,280 --> 00:06:39,800
perspectives simultaneously.

144
00:06:39,800 --> 00:06:45,560
Just like having a network of eyes in space giving us a much richer and more complete

145
00:06:45,560 --> 00:06:47,360
picture of what's out there.

146
00:06:47,360 --> 00:06:48,360
That's brilliant.

147
00:06:48,360 --> 00:06:52,800
And because they're relatively inexpensive, they're also great for testing new technologies

148
00:06:52,800 --> 00:06:55,000
without risking costly flagship missions.

149
00:06:55,000 --> 00:06:56,000
You got it.

150
00:06:56,000 --> 00:07:00,340
CubeSats are all about pushing boundaries and expanding the possibilities in space exploration.

151
00:07:00,340 --> 00:07:02,240
But it's not all smooth sailing.

152
00:07:02,240 --> 00:07:04,320
They do face some inherent challenges.

153
00:07:04,320 --> 00:07:05,320
That's right.

154
00:07:05,320 --> 00:07:06,320
There are always challenges.

155
00:07:06,320 --> 00:07:09,480
What are some of the limitations of working with something so small?

156
00:07:09,480 --> 00:07:11,440
Small size, of course, is a factor.

157
00:07:11,440 --> 00:07:15,280
Their limited size restricts the size and complexity of instruments they can carry.

158
00:07:15,280 --> 00:07:19,560
This affects power generation data storage and the overall lifespan of the mission.

159
00:07:19,560 --> 00:07:23,200
So they're limited in terms of how much power they can generate, how much data they can

160
00:07:23,200 --> 00:07:25,840
store, and how long they can operate in space.

161
00:07:25,840 --> 00:07:26,840
Precisely.

162
00:07:26,840 --> 00:07:29,000
And that brings us to the lifespan issue.

163
00:07:29,000 --> 00:07:30,000
OK.

164
00:07:30,000 --> 00:07:34,600
CubeSats typically operate for months or a few years, which makes long-term observations

165
00:07:34,600 --> 00:07:36,200
challenging.

166
00:07:36,200 --> 00:07:39,420
It's like capturing a glimpse of the universe before they fade away.

167
00:07:39,420 --> 00:07:42,120
So they're like the shooting stars of space exploration.

168
00:07:42,120 --> 00:07:44,000
Brilliant, but fleeting.

169
00:07:44,000 --> 00:07:45,840
That's a poetic way to put it.

170
00:07:45,840 --> 00:07:47,640
Another hurdle is communication.

171
00:07:47,640 --> 00:07:48,640
OK.

172
00:07:48,640 --> 00:07:53,040
Smaller antennas and limited bandwidth mean data transmission can be slower compared to

173
00:07:53,040 --> 00:07:54,040
larger satellites.

174
00:07:54,040 --> 00:07:55,040
That makes sense.

175
00:07:55,040 --> 00:07:56,040
Yeah.

176
00:07:56,040 --> 00:07:57,040
And what about space debris?

177
00:07:57,040 --> 00:07:58,040
Right.

178

00:12:28,220 --> 00:12:29,220
to address.

268
00:12:29,220 --> 00:12:30,220
That's right.

269
00:12:30,220 --> 00:12:34,040
We can't get carried away by the possibilities without considering the potential risks.

270
00:12:34,040 --> 00:12:36,400
You're referring to the issue of space debris.

271
00:12:36,400 --> 00:12:37,400
Yes.

272
00:12:37,400 --> 00:12:40,120
The sustainability of CubeSat missions is crucial.

273
00:12:40,120 --> 00:12:43,760
We need to ensure that these tiny explorers don't become part of the problem.

274
00:12:43,760 --> 00:12:48,960
So what are some of the ways we can mitigate the risk of CubeSats contributing to space

275
00:12:48,960 --> 00:12:49,960
debris?

276
00:12:49,960 --> 00:12:52,400
There are several approaches being explored.

277
00:12:52,400 --> 00:12:56,420
One is designing CubeSats with propulsion systems that allow them to de-orbit safely

278

at the end of their mission.

279
00:12:58,040 --> 00:13:01,660
So giving them a controlled death dive back to Earth where they'll burn up harmlessly

280
00:13:01,660 --> 00:13:02,660
in the atmosphere.

281
00:13:02,660 --> 00:13:03,660
Exactly.

282
00:13:03,660 --> 00:13:08,240
Another approach is using materials that naturally degrade in space, reducing the lifespan of

283
00:13:08,240 --> 00:13:09,240
debris.

284
00:13:09,240 --> 00:13:14,800

288
00:13:21,720 --> 00:13:24,240
It's like air traffic control, but for space.

289
00:13:24,240 --> 00:13:25,240
Precisely.

290
00:13:25,240 --> 00:13:30,280
We need to ensure that CubeSats, despite their small size, are operating safely and responsibly.

291
00:13:30,280 --> 00:13:34,400
It's a challenge, but one that we must overcome if we want to fully realize the potential

292
00:13:34,400 --> 00:13:37,840
of CubeSats for space exploration and scientific discovery.

293
00:13:37,840 --> 00:13:39,560
I completely agree.

294
00:13:39,560 --> 00:13:45,000
The future of CubeSats is bright, but it's up to us to ensure that it's also a sustainable

295
00:13:45,000 --> 00:13:46,000
one.

296
00:13:46,000 --> 00:13:50,000
Now let's shift gears a bit and talk about another exciting aspect of CubeSats, the potential

297
00:13:50,000 --> 00:13:51,840

00:14:32,200 --> 00:14:34,360
And the benefits are immense.

313
00:14:34,360 --> 00:14:38,560
Not only does it allow us to share knowledge and expertise, but it also fosters cultural

314
00:14:38,560 --> 00:14:41,640
understanding and strengthens diplomatic ties.

315
00:14:41,640 --> 00:14:45,640
So in a way, CubeSats are not just exploring the cosmos, they're exploring the potential

316
00:14:45,640 --> 00:14:47,840
for human collaboration.

317
00:14:47,840 --> 00:14:48,840
That's a great way to put it.

322
00:15:07,640 --> 00:15:09,420
That's a fascinating question.

323
00:15:09,420 --> 00:15:13,320
It seems like science fiction, but the more we learn about CubeSats, the more it feels

324
00:15:13,320 --> 00:15:14,320
like anything is possible.

325
00:15:14,320 --> 00:15:15,320
You're right.

326
00:15:15,320 --> 00:15:18,400
It might sound far-fetched, but the answer is surprisingly, maybe.

327
00:15:18,400 --> 00:15:19,400
Really?

328
00:15:19,400 --> 00:15:20,400
How so?

329
00:15:20,400 --> 00:15:23,300
Well, consider their adaptability and relatively low cost.

330
00:15:23,300 --> 00:15:27,900
They could be sent to explore potentially habitable environments within our own solar system.

331
00:15:27,900 --> 00:15:32,120
Like the icy moons of Jupiter and Saturn, which are thought to harbor vast oceans beneath

332
00:15:32,120 --> 00:15:33,360
their frozen surfaces.

333
00:15:33,360 --> 00:15:34,360
Exactly.

334
00:15:34,360 --> 00:15:38,760
We could equip these CubeSats with miniaturized instruments capable of detecting signs of

335
00:15:38,760 --> 00:15:39,760
life.

336
00:15:39,760 --> 00:15:44,480
They could analyze the chemical composition of plumes erupting from these icy moons, searching

337
00:15:44,480 --> 00:15:48,760
for biosignatures that might indicate the presence of microbial life.

338
00:15:48,760 --> 00:15:51,920
It wouldn't be easy, but it's within the realm of possibility.

339
00:15:51,920 --> 00:15:56,700
Sending a fleet of mini satellites on a mission to find alien life that would be revolutionary.

340
00:15:56,700 --> 00:16:01,520
And even if they don't find definitive proof of life, the data they collect could provide

341
00:16:01,520 --> 00:16:06,080
invaluable insights into the potential habitability of these distant worlds.

342
00:16:06,080 --> 00:16:07,680

And they're doing it all with a level of affordability and adaptability that was unimaginable just

348
00:16:28,480 --> 00:16:29,640
a few decades ago.

349
00:16:29,640 --> 00:16:34,140
It's a remarkable story of human ingenuity and the power of collaboration.

350
00:16:34,140 --> 00:16:36,160
And it's a story that's still being written.

351
00:16:36,160 --> 00:16:38,920
The future of CubeSats is bright full of possibilities.

352
00:16:38,920 --> 00:16:42,980
Who knows what incredible discoveries and breakthroughs await us thanks to these tiny

353
00:16:42,980 --> 00:16:44,760
but mighty explorers.

354
00:16:44,760 --> 00:16:49,040
Let's take a short break to delve into some specific examples of CubeSat missions that

355
00:16:49,040 --> 00:16:52,920
are pushing the boundaries of space exploration.

356
00:16:52,920 --> 00:16:54,240
Stay tuned.

357
00:16:54,240 --> 00:16:55,940
Welcome back to Cosmos in a Pod.

358
00:16:55,940 --> 00:17:00,040
Where we're wrapping up our exploration of the amazing world of CubeSats.

359
00:17:00,040 --> 00:17:04,280
These tiny satellites are truly revolutionizing the way we explore space.

360
00:17:04,280 --> 00:17:08,140
We've covered their advantages, the challenges they overcome, and the vast potential they

361
00:17:08,140 --> 00:17:09,140
hold for the future.

362
00:17:09,140 --> 00:17:13,440
And we've touched upon their broader impact on science, technology, and even international

363
00:17:13,440 --> 00:17:14,540
collaboration.

364
00:17:14,540 --> 00:17:18,920
But now it's time to zoom in on some specific CubeSat missions that are pushing the boundaries

365
00:17:18,920 --> 00:17:20,280
of space exploration.

366
00:17:20,280 --> 00:17:22,900
I'm eager to hear about these trailblazing missions.

367
00:17:22,900 --> 00:17:26,720
Let's start with a mission called QTE, CubeSat UV experiment.

368
00:17:26,720 --> 00:17:28,640
QT, I love the name.

369
00:17:28,640 --> 00:17:29,640
What's its mission objective?

370
00:17:29,640 --> 00:17:36,120
QTE is designed to study the atmospheres of exoplanets, those planets orbiting other stars.

371
00:17:36,120 --> 00:17:40,460
It's specifically focused on understanding how these atmospheres escape into space.

372
00:17:40,460 --> 00:17:43,760
Why is atmospheric escape such a crucial area of study?

373
00:17:43,760 --> 00:17:47,960
Well, the rate at which a planet loses its atmosphere can tell us a lot about its potential

374
00:17:47,960 --> 00:17:50,040
to support life as we know it.

375
00:17:50,040 --> 00:17:53,560
If an atmosphere escapes too quickly, it can make a planet inhospitable.

376
00:17:53,560 --> 00:17:54,560
That makes sense.

377
00:17:54,560 --> 00:17:59,480
So how does SUIT, a satellite the size of a cereal box, manage to study something as

378
00:17:59,480 --> 00:18:04,160
complex as atmospheric escape on planets light years away?

379
00:18:04,160 --> 00:18:05,160
It's quite remarkable.

380
00:18:05,160 --> 00:18:10,480
SUIT uses a specialized ultraviolet telescope to observe the light from exoplanets as they

381
00:18:10,480 --> 00:18:12,760
pass in front of their host stars.

382
00:18:12,760 --> 00:18:17,580
By analyzing this light, it can detect the signatures of escaping gases like hydrogen

383
00:18:17,580 --> 00:18:18,580
and helium.

384
00:18:18,580 --> 00:18:23,560
It's like a cosmic detective sniffing out the escaping atmospheres of distant worlds.

385
00:18:23,560 --> 00:18:24,560
That's incredible.

386
00:18:24,560 --> 00:18:28,200
What other missions are out there that showcase the ingenuity of CubeSat technology?

387
00:18:28,200 --> 00:18:32,600
Another fascinating mission is HaloSat, which is focused on studying the vast halo of hot

388
00:18:32,600 --> 00:18:35,360
gas that surrounds our own Milky Way galaxy.

389
00:18:35,360 --> 00:18:38,080
A halo of hot gas surrounding our galaxy?

390
00:18:38,080 --> 00:18:39,080
That sounds intriguing.

391
00:18:39,080 --> 00:18:43,640
Yes, this halo extends hundreds of thousands of light years beyond the visible disk of

392
00:18:43,640 --> 00:18:44,920
our galaxy.

393
00:18:44,920 --> 00:18:48,360
Astronomers believe it holds clues to the formation and evolution of galaxies.

394
00:18:48,360 --> 00:18:54,260
So HaloSat is helping us understand the bigger picture, the grand story of how galaxies like

395
00:18:54,260 --> 00:18:56,040
our own came to be.

396
00:18:56,040 --> 00:18:58,200
But how does it actually study this halo?

397
00:18:58,200 --> 00:19:02,360
HaloSat uses sensitive X-ray detectors to map the distribution and temperature of the

398
00:19:02,360 --> 00:19:04,480
hot gas in the halo.

399
00:19:04,480 --> 00:19:09,520
By studying these properties, astronomers can gain insights into how the halo formed,

400
00:19:09,520 --> 00:19:14,760
how it interacts with the rest of the galaxy, and what role it plays in the galactic ecosystem.

401
00:19:14,760 --> 00:19:18,480
It's amazing to think that a tiny CubeSat can help us unravel the mysteries of something

402
00:19:18,480 --> 00:19:21,480
as vast and complex as a galactic halo.

403
00:19:21,480 --> 00:19:22,480
Indeed.

404
00:19:22,480 --> 00:19:26,460
It speaks to the power of innovation and the potential of CubeSats to contribute to fundamental

405
00:19:26,460 --> 00:19:28,360
astrophysical research.

406
00:19:28,360 --> 00:19:32,840
What other missions out there highlight the versatility and adaptability of CubeSats?

407
00:19:32,840 --> 00:19:37,480
Well, there's Capstone, which is a pathfinder mission for NASA's Artemis program.

408
00:19:37,480 --> 00:19:41,760
Remember, Artemis aims to return humans to the moon, and Capstone is playing a crucial

409
00:19:41,760 --> 00:19:44,440
role in preparing for that ambitious endeavor.

410
00:19:44,440 --> 00:19:45,440
That's right.

411
00:19:45,440 --> 00:19:47,000
Artemis is a landmark mission.

412
00:19:47,000 --> 00:19:51,560
So how is a tiny CubeSat contributing to such a large-scale human spaceflight program?

413
00:19:51,560 --> 00:19:57,880
Capstone is testing a unique lunar orbit called a Near Rectilinear Halo Orbit, or NRHO for

414
00:19:57,880 --> 00:19:59,240
short.

415
00:19:59,240 --> 00:20:04,540
This orbit is special because it's very stable, requires minimal fuel to maintain, and provides

416
00:20:04,540 --> 00:20:06,980
excellent coverage of the lunar South Pole.

417
00:20:06,980 --> 00:20:09,400
Why is the lunar South Pole so important?

418
00:20:09,400 --> 00:20:13,920
That's where NASA plans to land the first woman and next man on the moon.

419
00:20:13,920 --> 00:20:18,760
The South Pole is thought to contain valuable resources like water ice, which could be crucial

420
00:20:18,760 --> 00:20:22,040
for establishing a sustainable human presence on the moon.

421
00:20:22,040 --> 00:20:26,840
So Capstone is essentially scouting out the landing site, ensuring its safety and viability

422
00:20:26,840 --> 00:20:28,760
for future human explorers.

423
00:20:28,760 --> 00:20:29,760
Exactly.

424
00:20:29,760 --> 00:20:34,200
And while it's doing that, it's also collecting valuable scientific data about the lunar environment,

425
00:20:34,200 --> 00:20:38,000
including its gravity field and the interaction of the solar wind with the lunar surface.

426
00:20:38,000 --> 00:20:42,000
It's a testament to the fact that CubeSats can contribute to both human exploration and

427
00:20:42,000 --> 00:20:43,000
scientific discovery.

428
00:20:43,000 --> 00:20:44,000
Indeed.

429
00:20:44,000 --> 00:20:46,600
And speaking of scientific discovery, let's talk about another exciting mission called

430
00:20:46,600 --> 00:20:48,080
Lunar Flashlight.

431
00:20:48,080 --> 00:20:49,080
Lunar Flashlight.

432
00:20:49,080 --> 00:20:50,080
That sounds intriguing.

433
00:20:50,080 --> 00:20:51,200
What's its objective?

434
00:20:51,200 --> 00:20:55,920
Lunar Flashlight is designed to use lasers to search for water ice in permanently shadowed

435
00:20:55,920 --> 00:20:58,160
craters at the lunar South Pole.

436
00:20:58,160 --> 00:21:02,140
We talked about water ice being a valuable resource on the moon.

437
00:21:02,140 --> 00:21:05,860
How will Lunar Flashlight search for it in these shadowed craters?

438
00:21:05,860 --> 00:21:12,080
It will reflect sunlight into these dark craters and analyze the reflected light using a spectrometer.

439
00:21:12,080 --> 00:21:15,480
The way the light is reflected can tell us about the composition of the surface within

440
00:21:15,480 --> 00:21:18,620
the craters, revealing the presence of water ice.

441
00:21:18,620 --> 00:21:22,000
So it's like shining a flashlight into the dark corners of the moon searching for those

442
00:21:22,000 --> 00:21:24,120
hidden reserves of water ice.

443
00:21:24,120 --> 00:21:25,120
Precisely.

444
00:21:25,120 --> 00:21:29,520
And this information will be crucial for planning future lunar missions and potentially establishing

445
00:21:29,520 --> 00:21:31,440
a long-term human presence on the moon.

446
00:21:31,440 --> 00:21:35,960
Well, I think it's safe to say that CubeSats are exceeding everyone's expectations.

447
00:21:35,960 --> 00:21:39,920
They're proving that size doesn't matter when it comes to making significant contributions

448
00:21:39,920 --> 00:21:40,920
to space exploration.

449
00:21:40,920 --> 00:21:43,000
I couldn't agree more.

450
00:21:43,000 --> 00:21:47,000
They're revolutionizing the field, making it more accessible, more affordable, and more

451
00:21:47,000 --> 00:21:48,680
innovative than ever before.

452
00:21:48,680 --> 00:21:50,140
And this is just the beginning.

453
00:21:50,140 --> 00:21:54,960
As technology continues to advance, we can only imagine the incredible discoveries and

454
00:21:54,960 --> 00:21:56,760
