00:00:06.879 --> 00:00:09.160
and we've got a stellar lineup of stories for you today.

4
00:00:09.560 --> 00:00:12.480
In this episode, we'll be exploring some groundbreaking developments in

5
00:00:12.519 --> 00:00:16.480
space technology and cosmic discoveries. We'll start with NASA's latest

6
00:00:16.480 --> 00:00:20.079
achievement in laser communications, which could revolutionize how we send

7
00:00:20.079 --> 00:00:23.480
and receive data from space. Then we'll dive into the

8
00:00:23.519 --> 00:00:26.039
fascinating world of asteroid mining and how it might just

9
00:00:26.079 --> 00:00:29.399
be the key to sustaining long duration space missions. We'll

10
00:00:29.399 --> 00:00:32.000
also take a peek at Blue Origins, ambitious plans for

11
00:00:32.039 --> 00:00:35.560
the first commercial space station. But that's not all. We'll

12
00:00:35.560 --> 00:00:38.920
discuss NASA's new category of space missions and wrap up

13
00:00:38.920 --> 00:00:42.200
with a cosmic drama involving a black hole, star destruction,

14
00:00:42.439 --> 00:00:46.079
and an unexpected collision. So strap in and get ready

15
00:00:46.079 --> 00:00:49.039
for a journey through the cosmos. This is Astronomy Daily,

16
00:00:49.439 --> 00:00:53.000
and we're about to take off. NASA has achieved a

17
00:00:53.039 --> 00:00:56.759
significant breakthrough in space communications technology with its low cost

18
00:00:56.799 --> 00:01:02.119
optical terminal ELCOT. This ground state, made from modified commercial hardware,

19
00:01:02.560 --> 00:01:06.599
has successfully transmitted its first laser communications uplink to space.

20
00:01:07.159 --> 00:01:10.519
The target of this groundbreaking transmission was t Bird the

21
00:01:10.640 --> 00:01:14.519
terabyte infrared delivery payload, a small device about the size

22
00:01:14.560 --> 00:01:17.040
of a tissue box that was formerly in low Earth orbit.

23
00:01:17.719 --> 00:01:21.200
During the first live sky test, Elcott managed to produce

24
00:01:21.359 --> 00:01:24.959
enough uplink intensity for tea Bird to identify the laser beacon,

25
00:01:25.400 --> 00:01:29.040
connect and maintain a connection for over three minutes. To

26
00:01:29.079 --> 00:01:32.799
put this achievement into perspective, connecting Elcott's laser beacon from

27
00:01:32.879 --> 00:01:36.959
Earth to tea Bird required an incredibly precise pointing accuracy

28
00:01:37.040 --> 00:01:40.239
of one milaranian that's equivalent to hitting a three foot

29
00:01:40.280 --> 00:01:42.959
target from a distance of more than eight American football

30
00:01:43.000 --> 00:01:46.959
fields away. This successful test marks a significant step forward

31
00:01:46.959 --> 00:01:50.359
for laser communications in space. In a real world scenario,

32
00:01:50.439 --> 00:01:52.959
the three minute connection time between te Bird and Elcott

33
00:01:52.959 --> 00:01:55.599
would be enough to transmit over five terabytes of critical

34
00:01:55.599 --> 00:01:58.480
science data that's equivalent to more than two thy five

35
00:01:58.560 --> 00:02:01.560
hundred hours of high definition in a single pass. The

36
00:02:01.599 --> 00:02:05.480
potential impact of this technology is enormous. Laser communications can

37
00:02:05.519 --> 00:02:08.240
transfer ten to one hundred times more data than traditional

38
00:02:08.319 --> 00:02:11.560
radio frequency waves. This means that as our space missions

39
00:02:11.639 --> 00:02:14.719
venture further into the solar System and beyond. We'll be

40
00:02:14.759 --> 00:02:18.479
able to maintain robust connections and receive unprecedented amounts of

41
00:02:18.520 --> 00:02:22.960
data from these distant explorers. NASA's Space Communications and Navigation

42
00:02:23.039 --> 00:02:27.759
Program is already implementing laser communications technology in various orbits,

43
00:02:28.319 --> 00:02:31.439
including the upcoming Artemis two mission. As we look to

44
00:02:31.479 --> 00:02:35.159
the future of space exploration, including potential missions to Mars,

45
00:02:35.759 --> 00:02:39.240
this technology could serve as a critical lifeline for astronauts

46
00:02:39.280 --> 00:02:43.520
and scientific instruments alike. The Alcott team continues to refine

47
00:02:43.520 --> 00:02:47.599
their pointing capabilities through additional tests, demonstrating the potential of

48
00:02:47.680 --> 00:02:51.280
laser communications to revolutionize our access to new data about Earth,

49
00:02:51.719 --> 00:02:55.159
our Solar System, and beyond. This breakthrough paves the way

50
00:02:55.240 --> 00:02:58.639
for a new era in space communications, promising to unlock

51
00:02:58.719 --> 00:03:02.759
new frontiers in our under standing of the Cosmos. In

52
00:03:02.759 --> 00:03:07.560
a groundbreaking development, researchers from Western Universities Institute for Earth

53
00:03:07.560 --> 00:03:11.560
and Space Exploration have unveiled a potential solution to one

54
00:03:11.599 --> 00:03:16.000
of the biggest challenges of long duration space missions, food supply.

55
00:03:16.479 --> 00:03:19.759
They've identified a way to produce edible biomass using microbes

56
00:03:19.759 --> 00:03:24.000
and organic compounds found in asteroids. This innovative process involves

57
00:03:24.080 --> 00:03:26.960
using high heat to break down the organic compounds in

58
00:03:27.039 --> 00:03:31.840
asteroids through a process called pyrolysis. The resulting hydrocarbons could

59
00:03:31.840 --> 00:03:34.759
then be fed to microbes, which would consume the organic

60
00:03:34.879 --> 00:03:39.000
material and produce biomass that's nutritionally valuable for humans. The

61
00:03:39.039 --> 00:03:43.439
researchers focused on carbonaceous chondrites, a type of asteroid that

62
00:03:43.479 --> 00:03:48.000
contains substantial amounts of water and organic matter. Asteroids like Benu,

63
00:03:48.080 --> 00:03:52.439
which NASA's Osyrius rex mission recently sampled, fall into this category.

64
00:03:52.879 --> 00:03:56.919
Calculations suggest that asteroids similar to Benu could potentially produce

65
00:03:56.960 --> 00:04:00.400
between fifty to six thousand, five hundred and five fifty

66
00:04:00.479 --> 00:04:04.560
metric tons of edible biomass. That's enough calories to support

67
00:04:04.599 --> 00:04:08.560
between six hundred and seventeen thousand astronaut life years, depending

68
00:04:08.599 --> 00:04:10.759
on how much of the asteroids organic matter can be

69
00:04:10.800 --> 00:04:15.319
converted into food. This method could revolutionize long duration space

70
00:04:15.360 --> 00:04:18.759
travel by allowing astronauts to rely on locally sourced food

71
00:04:19.199 --> 00:04:22.600
instead of carrying large quantities from Earth. However, there's still

72
00:04:22.639 --> 00:04:25.360
work to be done. Future studies will need to explore

73
00:04:25.399 --> 00:04:29.519
the practicalities of mining and processing asteroids during missions, as

74
00:04:29.560 --> 00:04:32.720
well as ensuring the resulting food is safe and palatable

75
00:04:32.759 --> 00:04:37.439
for human consumption. As NASA prepares to retire the International

76
00:04:37.480 --> 00:04:40.519
Space Station by the end of this decade, private companies

77
00:04:40.560 --> 00:04:43.560
are stepping up to fill the void. Blue Origin, the

78
00:04:43.600 --> 00:04:46.800
space company founded by Jeff Bezos, is leading the charge

79
00:04:46.800 --> 00:04:50.439
with an ambitious project called Orbital Reef. Imagine a floating

80
00:04:50.480 --> 00:04:54.560
business park in space, complete with sleeping quarters, social areas,

81
00:04:54.759 --> 00:04:57.800
and state of the art research facilities. That's exactly what

82
00:04:57.879 --> 00:05:00.399
Blue Origin is aiming to create with Orbital Refef set

83
00:05:00.480 --> 00:05:03.680
to launch by twenty thirty. This commercial space station will

84
00:05:03.759 --> 00:05:07.199
orbit three hundred and eleven miles above Earth and boast

85
00:05:07.240 --> 00:05:10.439
an impressive twenty nine thousand, three hundred cubic feet of

86
00:05:10.480 --> 00:05:14.759
habitable space. The station's modular design allows for future expansion,

87
00:05:15.040 --> 00:05:18.800
potentially growing into a larger base camp over time. Initially,

88
00:05:18.959 --> 00:05:22.480
Orbital Reef will accommodate up to ten people, including scientists,

89
00:05:22.519 --> 00:05:26.040
international astronauts, and even tourists. Yes, you heard that right.

90
00:05:26.560 --> 00:05:29.079
Space tourism could become a reality sooner than we think.

91
00:05:30.000 --> 00:05:32.439
One of the most exciting features planned for Orbital Reef

92
00:05:32.480 --> 00:05:35.439
is the opportunity for spacewalks. Tourists will be able to

93
00:05:35.519 --> 00:05:39.439
venture outside the station in specially designed capsules, offering breath

94
00:05:39.480 --> 00:05:42.360
taking views of Earth unlike anything possible from the ground.

95
00:05:42.759 --> 00:05:46.959
The station will also include hydroponic gardens to grow fresh produce,

96
00:05:47.360 --> 00:05:50.839
addressing one of the major challenges of long term space habitation.

97
00:05:51.439 --> 00:05:54.680
And for those worried about staying connected, fear not, Orbital

98
00:05:54.720 --> 00:05:57.600
Reef will come equipped with Wi Fi, allowing for video

99
00:05:57.639 --> 00:06:00.639
calls back to Earth with an unbeatable backdrop. As we

100
00:06:00.680 --> 00:06:03.959
look to the future of space exploration and commerce, projects

101
00:06:04.000 --> 00:06:07.120
like Orbital Reef represent a bold new frontier. It's an

102
00:06:07.120 --> 00:06:11.079
exciting time for space enthusiasts and aspiring astronauts alike, as

103
00:06:11.120 --> 00:06:13.920
the dream of living and working in space inches closer

104
00:06:13.959 --> 00:06:18.439
to reality. NASA has just unveiled an exciting new category

105
00:06:18.439 --> 00:06:21.720
of space missions called Probe Explorers. This new program is

106
00:06:21.759 --> 00:06:24.800
designed to bridge the gap between NASA's large scale flagship

107
00:06:24.839 --> 00:06:29.360
missions and their smaller exploration projects. The Probe Explorers program

108
00:06:29.439 --> 00:06:32.959
aims to foster creative ideas for exploring the universe, and

109
00:06:33.000 --> 00:06:35.519
it's already shaping up to be one of NASA's largest

110
00:06:35.600 --> 00:06:40.920
astrophysics initiatives. Nikola Fox, NASA's Associate Administrator of the Science

111
00:06:41.000 --> 00:06:45.000
Mission Directorate, praise the program for taking creativity to new heights.

112
00:06:45.399 --> 00:06:48.519
Two proposed missions are currently under consideration for the inaugural

113
00:06:48.600 --> 00:06:51.800
Probe Explorer launch. The first is the Advanced X Ray

114
00:06:51.800 --> 00:06:55.279
Imaging Satellite, which would provide a large flat field of

115
00:06:55.360 --> 00:06:59.480
view with high spatial resolution. This satellite could revolutionize our

116
00:06:59.560 --> 00:07:03.639
understanding of supermassive black holes and galaxy evolution. The second

117
00:07:03.639 --> 00:07:07.279
contender is the Probe Far Infrared Mission for Astrophysics. This

118
00:07:07.360 --> 00:07:10.720
one point eight meter telescope would study far infrared radiation

119
00:07:10.839 --> 00:07:14.759
in space, filling a crucial gap in our observation capabilities

120
00:07:15.079 --> 00:07:19.560
between the James Web Space Telescope and radio telescopes. Both

121
00:07:19.560 --> 00:07:22.199
projects will receive five million dollars for a twelve month

122
00:07:22.240 --> 00:07:26.160
concept study. After careful evaluation, NASA will select one of

123
00:07:26.199 --> 00:07:28.639
these missions in twenty twenty six for a planned launch

124
00:07:28.680 --> 00:07:31.319
in twenty thirty two. This new program is part of

125
00:07:31.439 --> 00:07:34.959
NASA's long running Explorers program, which has been providing low

126
00:07:35.000 --> 00:07:38.279
cost access to space since nineteen fifty eight, with over

127
00:07:38.399 --> 00:07:41.639
ninety successful science led missions to date. The addition of

128
00:07:41.680 --> 00:07:44.319
Probe Explorers promises to usher in a new era of

129
00:07:44.319 --> 00:07:49.639
cosmic discovery and innovation in a cosmic drama of epic proportions,

130
00:07:49.720 --> 00:07:53.079
Astronomers have witnessed a massive black hole engaged in a

131
00:07:53.120 --> 00:07:57.639
destructive rampage. This celestial behemoth first tore apart an unfortunate

132
00:07:57.639 --> 00:08:00.439
star that ventured too close, and is now now using

133
00:08:00.480 --> 00:08:03.959
the stellar debris as ammunition to pummel another nearby object.

134
00:08:04.240 --> 00:08:08.040
This extraordinary discovery was made possible through the combined efforts

135
00:08:08.079 --> 00:08:12.639
of multiple NASA observatories, including the Chandra X ray Observatory,

136
00:08:13.000 --> 00:08:17.199
Hubble Space Telescope, and the Nicer instrument aboard the International

137
00:08:17.199 --> 00:08:20.480
Space Station. The story begins in twenty nineteen when astronomers

138
00:08:20.480 --> 00:08:23.839
observed a star being shredded by the immense gravitational forces

139
00:08:23.839 --> 00:08:26.920
of a supermassive black hole. This violent event, known as

140
00:08:26.920 --> 00:08:30.160
a tidal disruption, left behind a disc of stellar remains

141
00:08:30.240 --> 00:08:33.440
orbiting the black hole, but the cosmic spectacle didn't end there.

142
00:08:33.799 --> 00:08:36.879
Over the next few years, this debris disc expanded outward,

143
00:08:37.200 --> 00:08:40.120
setting the stage for an even more dramatic encounter. The

144
00:08:40.159 --> 00:08:44.120
expanding disc has now collided with another celestial body, either

145
00:08:44.159 --> 00:08:47.399
a star or a smaller black hole that was previously

146
00:08:47.519 --> 00:08:50.799
orbiting at a safe distance from the central supermassive black hole.

147
00:08:51.720 --> 00:08:54.320
This collision is creating repeated bursts of X rays as

148
00:08:54.360 --> 00:08:57.519
the orbiting object plows through the debris disc approximately every

149
00:08:57.519 --> 00:09:00.399
forty eight hours. It's like watching a cosmme game of

150
00:09:00.399 --> 00:09:04.440
bumper cars, but with far more devastating consequences. What makes

151
00:09:04.480 --> 00:09:07.720
this discovery particularly exciting is that it provides a crucial

152
00:09:07.759 --> 00:09:12.919
link between two previously mysterious phenomena, tidal disruption events and

153
00:09:13.000 --> 00:09:17.759
quasi periodic eruptions. Scientists have long suspected a connection between

154
00:09:17.799 --> 00:09:20.519
these two types of events, and now they have the

155
00:09:20.559 --> 00:09:23.919
evidence to prove it. This cosmic collision is not only

156
00:09:23.919 --> 00:09:27.799
a spectacular display of the universe's violent nature, but also
