1
00:00:00.120 --> 00:00:01.679
Hello, and welcome to Astronomy Daily.

2
00:00:01.720 --> 00:00:04.639
I'm excited to bring you another fascinating roundup of space

3
00:00:04.639 --> 00:00:08.400
and astronomy news. Today, we have another great lineup of

4
00:00:08.439 --> 00:00:12.599
stories that showcase both human ingenuity and our expanding understanding

5
00:00:12.640 --> 00:00:15.919
of the Cosmos. We'll start with the dramatic rescue of

6
00:00:15.919 --> 00:00:18.920
two astronauts who were stranded in space for nine months

7
00:00:19.559 --> 00:00:22.239
and explore what this means for the future of space

8
00:00:22.320 --> 00:00:24.120
law and rescue operations.

9
00:00:24.760 --> 00:00:27.440
Then we'll look at some cutting edge spacecraft.

10
00:00:26.839 --> 00:00:29.920
Technology being developed in Europe that could help solve our

11
00:00:29.920 --> 00:00:31.120
space debris problem.

12
00:00:31.960 --> 00:00:33.159
We'll also dive into the.

13
00:00:33.079 --> 00:00:37.759
Preparations for dream Chaser's historic first flight, examine groundbreaking new

14
00:00:37.799 --> 00:00:42.159
images of our infant universe, and explore intriguing new theories.

15
00:00:41.920 --> 00:00:43.439
About how life began on Earth.

16
00:00:44.280 --> 00:00:47.960
Plus, we'll look at ambitious plans to mine valuable resources

17
00:00:47.960 --> 00:00:50.679
on the Moon. Stay with me as we journey through

18
00:00:50.719 --> 00:00:53.960
these remarkable developments in space exploration and discovery.

19
00:00:54.399 --> 00:00:56.479
And of course I'll kick things off today with the

20
00:00:56.520 --> 00:00:57.640
story the Whole World.

21
00:00:57.520 --> 00:01:02.119
Seems to be talking about nificant development for space operations.

22
00:01:02.640 --> 00:01:06.879
Astronauts Sunny Williams and Butch Wilmore have finally returned safely

23
00:01:06.920 --> 00:01:10.879
to Earth aboard SpaceX's Dragon capsule after an extended nine

24
00:01:10.920 --> 00:01:14.920
months stay on the International Space Station. Their prolonged stay

25
00:01:15.000 --> 00:01:19.159
wasn't planned. It began when their experimental Boeing Starliner spacecraft

26
00:01:19.200 --> 00:01:22.799
experienced malfunctions last June, making it too risky for their

27
00:01:22.840 --> 00:01:27.359
return journey. This unprecedented situation has brought to light critical

28
00:01:27.439 --> 00:01:31.280
questions about space rescue operations, particularly as we enter an

29
00:01:31.280 --> 00:01:35.040
era where space travel isn't limited to traditional astronauts. With

30
00:01:35.159 --> 00:01:39.359
civilians like William Shatner, Jeff Bezos, and Richard Branson already

31
00:01:39.439 --> 00:01:42.359
venturing into space, in celebrities like Katy Perry and Gail

32
00:01:42.480 --> 00:01:46.879
King planning upcoming flights, the need for clear rescue protocols

33
00:01:47.239 --> 00:01:50.599
has never been more pressing. The challenge lies in the

34
00:01:50.640 --> 00:01:53.840
current state of space law, which hasn't kept pace with

35
00:01:53.879 --> 00:01:58.480
the rapid commercialization of space travel. While international space law

36
00:01:58.519 --> 00:02:03.000
requires countries to rescue as astronauts regardless of nationality, there's

37
00:02:03.040 --> 00:02:07.400
significant uncertainty about whether private space companies have similar obligations.

38
00:02:07.920 --> 00:02:11.199
This legal vacuum becomes particularly concerning when we consider the

39
00:02:11.199 --> 00:02:15.000
growing number of space tourists. Space policy experts are now

40
00:02:15.039 --> 00:02:19.120
calling for two crucial reforms, first, a broader interpretation of

41
00:02:19.120 --> 00:02:22.840
the term astronaut to ensure rescue rights extend to all

42
00:02:22.879 --> 00:02:28.000
space travelers, and second, clear guidelines determining responsibility for rescuing

43
00:02:28.000 --> 00:02:32.240
private citizens in space emergencies. The pressing concern is that,

44
00:02:32.680 --> 00:02:36.039
without proper oversight, space tourism companies might require customers to

45
00:02:36.080 --> 00:02:40.120
waive their right to rescue, a potentially dangerous precedent. This

46
00:02:40.280 --> 00:02:43.520
rescue mission's success is certainly a relief for NASA, but

47
00:02:43.599 --> 00:02:45.639
it serves as a wake up call for the international

48
00:02:45.719 --> 00:02:49.120
space community. As we continue to push the boundaries of

49
00:02:49.120 --> 00:02:52.680
space exploration and tourism, we need to ensure our legal

50
00:02:52.719 --> 00:02:56.560
frameworks evolved to protect everyone who ventures beyond Earth's atmosphere.

51
00:02:57.879 --> 00:03:01.039
Let's turn our attention now to another press problem in space.

52
00:03:01.800 --> 00:03:04.719
A group of European companies has embarked on an innovative

53
00:03:04.759 --> 00:03:08.960
project to tackle the growing challenge of space debris. Led

54
00:03:09.000 --> 00:03:13.479
by Portuguese startup Spaceio, the consortium has secured three million

55
00:03:13.520 --> 00:03:17.000
euros in funding from the European Space Agency to test

56
00:03:17.039 --> 00:03:20.000
an inflatable drag sale designed to help satellites return to

57
00:03:20.039 --> 00:03:24.199
Earth more efficiently. This groundbreaking system starts at just twenty

58
00:03:24.199 --> 00:03:27.280
square centimeters, but can inflate to an impressive one point

59
00:03:27.319 --> 00:03:31.319
five square meters once deployed. The dramatic size increase creates

60
00:03:31.319 --> 00:03:36.120
significant atmospheric drag, allowing satellites to diorbit much more quickly

61
00:03:36.159 --> 00:03:39.439
than they would naturally. Instead of taking a decade to

62
00:03:39.479 --> 00:03:43.319
burn up in the atmosphere, satellites equipped with this technology

63
00:03:43.360 --> 00:03:47.000
could complete their descent in just over a year. While

64
00:03:47.000 --> 00:03:50.120
the initial test will involve a relatively small twelve unit

65
00:03:50.159 --> 00:03:54.080
cube SAT, the technology has potential applications for satellites up

66
00:03:54.120 --> 00:03:57.800
to two hundred kilograms. What makes the system particularly valuable

67
00:03:57.960 --> 00:04:01.159
is its ability to function even if the satellite itself

68
00:04:01.199 --> 00:04:05.719
fails or malfunctions, unlike traditional propulsion based deorbiting methods that

69
00:04:05.800 --> 00:04:10.319
require the satellite to remain operational. The SWIFT project, which

70
00:04:10.360 --> 00:04:14.800
stands for Spacecraft with Inflatable Termination, brings together expertise from

71
00:04:14.800 --> 00:04:19.240
across Europe. French company space Locker will handle integration, Dutch

72
00:04:19.319 --> 00:04:22.600
firm gam Space will provide the host satellite, and solid

73
00:04:22.639 --> 00:04:25.680
Flow from the Netherlands will develop the critical gas generation

74
00:04:25.759 --> 00:04:29.759
system needed for inflation. This development comes at a crucial

75
00:04:29.839 --> 00:04:33.079
time as the number of satellites in orbit continues to

76
00:04:33.120 --> 00:04:37.360
grow exponentially by providing a reliable and autonomous method for

77
00:04:37.399 --> 00:04:41.279
removing defunct satellites from orbit. This technology could play a

78
00:04:41.360 --> 00:04:44.600
vital role in maintaining the long term sustainability of our

79
00:04:44.680 --> 00:04:49.000
orbital environment and preventing the accumulation of dangerous space debris.

80
00:04:50.040 --> 00:04:53.040
The team plans to demonstrate this innovative deorbiting system in

81
00:04:53.079 --> 00:04:56.319
low Earth orbit by twenty twenty eight, marking a significant

82
00:04:56.360 --> 00:05:01.399
step forward in responsible space operations and debris mitigation effort.

83
00:05:01.680 --> 00:05:06.600
In exciting developments for space exploration, Sierra Space's Dream Chaser

84
00:05:06.720 --> 00:05:10.920
spacecraft is entering its final testing phase before its historic

85
00:05:10.959 --> 00:05:15.519
first flight to the International Space Station. Nicknamed the Mini Shuttle,

86
00:05:16.120 --> 00:05:18.839
this spacecraft will be the first since the retirement of

87
00:05:18.879 --> 00:05:21.839
the Space Shuttle program in twenty eleven to dock with

88
00:05:21.879 --> 00:05:25.240
the ISS and then return to Earth via runway landing.

89
00:05:26.160 --> 00:05:30.040
The first Dream Chaser vehicle, named Tenacity, is currently in

90
00:05:30.079 --> 00:05:35.839
Florida undergoing crucial preflight testing. The spacecraft must complete electromagnetic

91
00:05:35.879 --> 00:05:39.399
interference testing and acoustic chamber trials to ensure it can

92
00:05:39.439 --> 00:05:43.959
withstand the intense vibrations of launch. These tests will verify

93
00:05:44.040 --> 00:05:47.160
that all onboard systems can function properly in the harsh

94
00:05:47.240 --> 00:05:51.639
environment of space. Tenacity will launch a board ULA's new

95
00:05:51.759 --> 00:05:55.759
Vulcan rocket and carry over three thousand, five hundred kilograms

96
00:05:55.759 --> 00:05:59.399
of supplies and science equipment to the ISS. The vehicle

97
00:05:59.480 --> 00:06:02.240
is designed to remain docked to the station for between

98
00:06:02.240 --> 00:06:06.439
thirty and ninety days, depending on mission requirements. One of

99
00:06:06.519 --> 00:06:10.920
dream Chaser's most remarkable features is its advanced thermal protection system.

100
00:06:11.439 --> 00:06:14.360
Unlike the Space Shuttle's mixed use of tiles and blankets,

101
00:06:14.759 --> 00:06:18.439
Tenacity is covered in approximately two thousand specialized black and

102
00:06:18.480 --> 00:06:22.279
white tiles. These tiles can withstand temperatures up to two thousand,

103
00:06:22.360 --> 00:06:26.439
six hundred degrees fahrenheit across multiple re entry cycles, while

104
00:06:26.480 --> 00:06:30.839
also helping regulate the spacecraft's temperature during orbital operations. The

105
00:06:30.920 --> 00:06:35.279
vehicle's design includes several key safety improvements over the Space Shuttle.

106
00:06:35.879 --> 00:06:39.839
Dream Chaser launches inside a protective firing, preventing the tile

107
00:06:39.920 --> 00:06:43.040
damage from falling foam or ice that plagued the Shuttle program.

108
00:06:43.639 --> 00:06:47.279
It also uses a more environmentally friendly propulsion system, combining

109
00:06:47.279 --> 00:06:51.959
refined kerosene with hydrogen peroxide instead of toxic hypergolic fuels.

110
00:06:52.879 --> 00:06:55.560
Sierra Space has already begun work on a second vehicle

111
00:06:55.639 --> 00:06:58.839
named Reverence, which is being assembled at their Dream Factory

112
00:06:58.879 --> 00:07:02.600
in Colorado, with Tenacity scheduled to fly the first four

113
00:07:02.639 --> 00:07:06.000
missions and Reverence taking over from the fifth flight onward.

114
00:07:06.439 --> 00:07:11.240
Dreamchaser represents an exciting new chapter in space transportation, combining

115
00:07:11.279 --> 00:07:16.120
the best features of past spacecraft with modern innovations. The

116
00:07:16.160 --> 00:07:20.519
Atacama Cosmology Telescope in Chile has captured groundbreaking new images

117
00:07:20.680 --> 00:07:23.160
that give us our most detailed look yet at the

118
00:07:23.199 --> 00:07:28.319
infant universe. These remarkable baby pictures show the cosmos just

119
00:07:28.399 --> 00:07:32.079
three hundred eighty thousand years after the Big Bang, revealing

120
00:07:32.079 --> 00:07:35.920
the universe's first steps toward forming stars and galaxies. With

121
00:07:36.160 --> 00:07:41.199
unprecedented clarity, The images capture what's known as the cosmic

122
00:07:41.399 --> 00:07:44.839
microwave background, the afterglow of the first light that was

123
00:07:44.879 --> 00:07:48.639
able to travel freely through space. Before this moment, the

124
00:07:48.800 --> 00:07:51.800
universe was so hot and dense that light couldn't move

125
00:07:51.879 --> 00:07:55.959
without being scattered by free electrons. But as the cosmos

126
00:07:56.040 --> 00:08:00.439
expanded and cooled, atoms formed and light could finally travel

127
00:08:00.560 --> 00:08:05.600
unimpeded through space. What makes these new observations so special

128
00:08:05.720 --> 00:08:10.120
is their extraordinary precision. The Telescope's images are five times

129
00:08:10.120 --> 00:08:13.399
sharper than previous observations and show both the intensity and

130
00:08:13.480 --> 00:08:17.439
polarization of this ancient light. This allows scientists to see

131
00:08:17.439 --> 00:08:20.120
not just where matter was located in the early universe,

132
00:08:20.480 --> 00:08:24.199
but how it was moving. The data reveals subtle variations

133
00:08:24.199 --> 00:08:27.279
in density and velocity of the primordial gases that filled

134
00:08:27.279 --> 00:08:30.600
the young cosmos. We can now see vast regions of

135
00:08:30.720 --> 00:08:34.080
higher and lower density extending millions of light years across

136
00:08:34.720 --> 00:08:38.039
over billions of years. Gravity would pull these denser regions inward,

137
00:08:38.600 --> 00:08:41.919
eventually leading to the formation of the first stars and galaxies.

138
00:08:43.000 --> 00:08:46.240
These findings have helped validate our standard model of cosmology,

139
00:08:46.720 --> 00:08:51.120
showing it to be remarkably robust. The observations indicate that

140
00:08:51.159 --> 00:08:55.759
the observable universe extends about fifty billion light years in

141
00:08:55.919 --> 00:08:59.279
all directions, with a total mass equivalent to about two

142
00:08:59.320 --> 00:09:04.480
trillion trillis in suns. Of this cosmic inventory, ordinary matter

143
00:09:04.519 --> 00:09:07.720
makes up only about five percent, while dark matter accounts

144
00:09:07.720 --> 00:09:10.960
for about twenty six percent and the mysterious dark energy

145
00:09:10.960 --> 00:09:15.200
comprises the remaining sixty nine percent. The images provide an

146
00:09:15.360 --> 00:09:19.600
unprecedented window into our cosmic origins, allowing us to witness

147
00:09:19.600 --> 00:09:22.879
the universe taking its very first steps toward becoming the

148
00:09:23.000 --> 00:09:27.600
rich and complex cosmos we see today. Next up, a

149
00:09:27.639 --> 00:09:30.679
subject we keep revisiting, but one we all have an

150
00:09:30.720 --> 00:09:34.799
interest in. Recent research has revealed an intriguing new theory

151
00:09:35.039 --> 00:09:38.360
about how life might have emerged on Earth. Scientists at

152
00:09:38.360 --> 00:09:43.399
Stanford University have discovered that micro lightning, tiny electrical discharges

153
00:09:43.440 --> 00:09:47.120
between water droplets could have provided the spark needed to

154
00:09:47.159 --> 00:09:51.559
create life's building blocks. This challenges the traditional view that

155
00:09:51.639 --> 00:09:56.240
only powerful atmospheric lightning could have triggered these crucial chemical reactions.

156
00:09:56.559 --> 00:10:00.360
When water droplets separate through splashing or spraying, they develop

157
00:10:00.399 --> 00:10:04.559
different electrical charges. Larger drops tend to become positively charged,

158
00:10:04.759 --> 00:10:08.240
while smaller ones take on negative charges. When these oppositely

159
00:10:08.320 --> 00:10:12.960
charged droplets come close together, they create microscopic lightning strikes.

160
00:10:13.480 --> 00:10:17.600
These tiny electrical discharges appear capable of producing the same

161
00:10:17.759 --> 00:10:22.360
organic molecules previously seen in famous origin of life experiments.

162
00:10:23.360 --> 00:10:27.039
The researchers demonstrated that this micro lightning can create important

163
00:10:27.080 --> 00:10:31.879
carbon nitrogen bonds and form compounds essential for life, including

164
00:10:31.960 --> 00:10:35.879
amino acids and components of RNA. This process could have

165
00:10:35.879 --> 00:10:39.840
been widespread on early Earth occurring wherever water sprayed against

166
00:10:39.960 --> 00:10:43.240
rocks or in ocean waves, making it a more plausible

167
00:10:43.279 --> 00:10:48.360
mechanism for life's origins than rare lightning strikes. In other

168
00:10:48.399 --> 00:10:52.720
fascinating developments, a Seattle based company called Interlune has announced

169
00:10:52.720 --> 00:10:56.240
ambitious plans to prospect the Moon for helium three. This

170
00:10:56.440 --> 00:10:59.759
rare isotope, currently valued at around twenty million dollars per

171
00:10:59.799 --> 00:11:04.320
kil telegram, could potentially power future nuclear fusion reactors. The

172
00:11:04.320 --> 00:11:07.639
Moon's surface contains an estimated one million metric tons of

173
00:11:07.679 --> 00:11:11.679
helium three deposited there over billions of years by solar winds.

174
00:11:12.559 --> 00:11:15.440
Interlun plans to launch their prospect Moon mission in twenty

175
00:11:15.480 --> 00:11:19.480
twenty seven, equipped with specialized systems to sample and process

176
00:11:19.559 --> 00:11:22.919
lunar regalith They'll focus on areas rich in a mineral

177
00:11:22.960 --> 00:11:26.840
called ilmanite, which tends to trap helium three. The company

178
00:11:26.840 --> 00:11:30.360
aims to demonstrate the feasibility of extracting this valuable resource

179
00:11:30.720 --> 00:11:36.120
while contributing important scientific data about the Moon's composition. And

180
00:11:36.159 --> 00:11:39.639
that's all for today's episode of Astronomy Daily. If you'd
