00:00:00.200 --> 00:00:02.799
Welcome to Astronomy Daily. I'm excited to bring you another

2
00:00:02.879 --> 00:00:06.040
packed episode of space and astronomy News. Today, we have

3
00:00:06.120 --> 00:00:09.279
some great stories to share, starting with a groundbreaking discovery

4
00:00:09.320 --> 00:00:13.119
about Jupiter's volcanic moon Io that's challenging everything we thought

5
00:00:13.119 --> 00:00:16.320
we knew about its interior structure. We'll also look at

6
00:00:16.320 --> 00:00:20.120
an incredibly busy week ahead in spaceflight, with multiple launches

7
00:00:20.160 --> 00:00:23.719
scheduled from SpaceX, including their next crew mission to the

8
00:00:23.760 --> 00:00:28.719
International Space Station. Rocket Lab Firefly, and several international launch

9
00:00:28.719 --> 00:00:31.640
providers are also preparing for liftoffs in the coming days.

10
00:00:32.240 --> 00:00:36.000
In our coverage of cosmic mysteries, we'll explore fascinating new

11
00:00:36.039 --> 00:00:38.479
research about dark matter at the heart of our Milky

12
00:00:38.479 --> 00:00:42.960
Way galaxy that could revolutionize our understanding of this enigmatic substance.

13
00:00:43.880 --> 00:00:46.200
We'll also check in on NASA's Artemis program as it

14
00:00:46.240 --> 00:00:50.119
takes another step toward returning humans to the Moon, and

15
00:00:50.159 --> 00:00:52.200
we'll round things out with an interesting look at some

16
00:00:52.280 --> 00:00:56.520
growing pains at SpaceX, where recent challenges might suggest the

17
00:00:56.520 --> 00:01:00.240
company is approaching its operational limits even as it maintains

18
00:01:00.240 --> 00:01:04.400
an unprecedented launch cadence. Let's dive into these stories and

19
00:01:04.439 --> 00:01:09.400
explore the latest developments in space exploration and astronomy. In

20
00:01:09.400 --> 00:01:14.040
a fascinating development, NASA's junospacecraft has revealed surprising new insights

21
00:01:14.319 --> 00:01:18.599
about Jupiter's most volcanic moon, Io. Data from recent flybys

22
00:01:18.599 --> 00:01:21.519
suggests that, contrary to long held beliefs, Io doesn't have

23
00:01:21.560 --> 00:01:25.239
a shallow global magma ocean beneath its surface. Instead, the

24
00:01:25.239 --> 00:01:28.959
moon's mantle appears to be mostly solid, forcing scientists to

25
00:01:29.000 --> 00:01:32.799
rethink their understanding of how this incredibly active world functions.

26
00:01:33.840 --> 00:01:38.680
Io experiences intense geological activity due to the powerful gravitational

27
00:01:38.680 --> 00:01:42.120
forces from Jupiter. As the Moon follows its elliptical orbit,

28
00:01:42.480 --> 00:01:47.200
Jupiter's massive gravitational pull stretches and compresses it, generating tremendous

29
00:01:47.239 --> 00:01:51.519
internal heat. This process, known as tidal heating, is responsible

30
00:01:51.560 --> 00:01:55.000
for Io's status as the most volcanically active body in

31
00:01:55.040 --> 00:01:59.640
our Solar system. For years, scientists theorized that this constant

32
00:01:59.680 --> 00:02:04.040
gravitational needing could create and maintain a global underground ocean

33
00:02:04.359 --> 00:02:09.080
of molten rock. However, when researchers analyzed measurements of Io's

34
00:02:09.080 --> 00:02:13.439
tidal deformation, how much its surface flexes under Jupiter's gravitational stress,

35
00:02:13.919 --> 00:02:16.960
the data told a different story. The team led by

36
00:02:17.039 --> 00:02:19.960
Ryan Park found that the way Io responds to these

37
00:02:20.000 --> 00:02:22.960
forces isn't consistent with what we'd expect if a shallow

38
00:02:23.039 --> 00:02:26.400
magma ocean were present. The findings don't rule out the

39
00:02:26.439 --> 00:02:29.800
possibility of some deeper magma chambers or isolated pockets of

40
00:02:29.840 --> 00:02:34.120
molten rock, but they do suggest that Io's internal structure

41
00:02:34.280 --> 00:02:38.520
is more complex than previously thought. This discovery has broader

42
00:02:38.520 --> 00:02:42.360
implications for our understanding of how tidal forces affect worlds

43
00:02:42.400 --> 00:02:46.240
throughout the Solar System, including other moons like Europa and

44
00:02:46.360 --> 00:02:51.199
Enceladus that experience similar gravitational interactions with their parent planets.

45
00:02:52.479 --> 00:02:55.400
This revelation from Juno adds another layer to our evolving

46
00:02:55.439 --> 00:02:59.120
picture of Io, showing us that even after decades of observation,

47
00:02:59.639 --> 00:03:03.280
this fascinating moon still has secrets to reveal. The findings

48
00:03:03.360 --> 00:03:06.159
challenge us to develop new models to explain how Io

49
00:03:06.319 --> 00:03:10.560
maintains its extraordinary volcanic activity without a global magma ocean,

50
00:03:10.960 --> 00:03:14.479
opening up exciting new questions for planetary scientists to explore.

51
00:03:15.960 --> 00:03:18.520
Let's turn our attention now to this week's launch roster.

52
00:03:18.960 --> 00:03:21.919
Get ready for an incredibly busy week in spaceflight, with

53
00:03:22.000 --> 00:03:26.439
multiple launches scheduled across the globe. SpaceX leads the packed

54
00:03:26.439 --> 00:03:30.360
schedule with several missions, including the highly anticipated Crew ten

55
00:03:30.400 --> 00:03:33.680
flight to the International Space Station. The Crew ten mission

56
00:03:33.719 --> 00:03:36.919
will launch from Kennedy Space Center's Launch Complex thirty nine A,

57
00:03:37.560 --> 00:03:42.159
carrying NASA astronauts A. McLean and Nicole Ayers JACKSA astronaut

58
00:03:42.199 --> 00:03:46.360
to Kuya Onishi and Roscosmos cosmonaut kirol Peskov to the

59
00:03:46.360 --> 00:03:50.120
space Station. They'll be flying aboard the Crew Dragon Endurance,

60
00:03:50.599 --> 00:03:54.680
making its fourth trip to space. This particular Dragon previously

61
00:03:54.680 --> 00:03:57.599
supported the Crew three, Crew five, and Crew seven missions.

62
00:03:58.120 --> 00:04:01.960
SpaceX also has multiple Starlink launches on the manifest, including

63
00:04:02.000 --> 00:04:05.639
two missions from Florida's Space Coast. These launches will continue

64
00:04:05.639 --> 00:04:08.840
expanding the company's satellite Internet constellation, with some of the

65
00:04:08.840 --> 00:04:12.039
satellites featuring new direct to cell capabilities that could eventually

66
00:04:12.120 --> 00:04:16.600
enable mobile phone connectivity from space. In California, SpaceX had

67
00:04:16.600 --> 00:04:20.439
planned to launch two NASA science missions, SPHEREx and Punch.

68
00:04:20.959 --> 00:04:23.240
SPHEREx will study the early universe and search for the

69
00:04:23.240 --> 00:04:26.519
building blocks of life within our galaxy, while Punch will

70
00:04:26.560 --> 00:04:29.959
investigate solar winds and their effects on the heliosphere using

71
00:04:30.000 --> 00:04:33.720
a network of four small satellites. However, I believe this

72
00:04:33.800 --> 00:04:37.160
launch has just been delayed and will be rescheduled. Rocket

73
00:04:37.199 --> 00:04:39.800
Lab is preparing for their third mission of twenty twenty

74
00:04:39.800 --> 00:04:43.519
five from New Zealand, appropriately titled the Lightning God Rains.

75
00:04:44.199 --> 00:04:48.079
They'll be launching a synthetic aperture radar satellite for IQPS,

76
00:04:48.120 --> 00:04:50.720
marking the first of eight planned launches to help build

77
00:04:50.720 --> 00:04:54.839
out their Earth observation constellation. Firefly Aerospace is set to

78
00:04:54.920 --> 00:04:58.560
launch their Alpha rocket from Vandenberg Space Force Base, carrying

79
00:04:58.600 --> 00:05:01.959
Lockheed Martin's new LA M four hundred satellite bus on

80
00:05:02.040 --> 00:05:05.519
a demonstration mission. This will be Alpha's first flight of

81
00:05:05.560 --> 00:05:09.879
the year and sixth overall. On the international front, China's

82
00:05:09.920 --> 00:05:12.680
chang Jung eight rocket will make history with the first

83
00:05:12.759 --> 00:05:15.759
launch from a new commercial pad at Wenchang, while Russia

84
00:05:15.839 --> 00:05:19.839
prepares an Angara rocket launch from Plasetsk carrying an unspecified

85
00:05:19.839 --> 00:05:24.959
military payload. This intense launch cadence reflects the growing commercialization

86
00:05:25.079 --> 00:05:29.439
of space access and the increasing diversity of launch providers worldwide.

87
00:05:29.839 --> 00:05:32.120
It's a testament to how far we've come from the

88
00:05:32.199 --> 00:05:36.079
days when orbital launches were rare events, sometimes happening only

89
00:05:36.120 --> 00:05:41.560
a few times per year. Next up. A fascinating discovery

90
00:05:41.560 --> 00:05:44.279
at the heart of our Milky Way galaxy could provide

91
00:05:44.319 --> 00:05:47.879
new insights into one of the universe's most perplexing mysteries.

92
00:05:48.399 --> 00:05:52.560
Dark matter. Scientists have identified strange events in the galaxy's

93
00:05:52.560 --> 00:05:55.920
central molecular zone that might be evidence of a previously

94
00:05:56.000 --> 00:05:59.160
unknown form of dark matter, one that's lighter than existing

95
00:05:59.199 --> 00:06:03.959
theoretical candidate. This new dark matter suspect has a unique characteristic,

96
00:06:04.079 --> 00:06:07.800
its self annihilating. When two particles meet, they destroy each other,

97
00:06:07.879 --> 00:06:12.480
creating pairs of electrons and their antimatter counterparts positrons. This

98
00:06:12.560 --> 00:06:16.079
process releases energy that strips electrons from neutral atoms in

99
00:06:16.120 --> 00:06:19.240
the dense gas at our galaxy center, a process known

100
00:06:19.279 --> 00:06:23.160
as ionization. The theory elegantly explains why there's so much

101
00:06:23.240 --> 00:06:26.839
ionized gas in the central molecular zone. While this annihilation

102
00:06:26.959 --> 00:06:30.000
process might be rare, it would naturally occur more frequently

103
00:06:30.040 --> 00:06:33.000
in galactic centers where dark matter is thought to concentrate.

104
00:06:33.839 --> 00:06:37.639
Traditional explanations involving cosmic rays don't fully account for the

105
00:06:37.680 --> 00:06:42.279
observed levels of ionization, and importantly don't match other expected

106
00:06:42.319 --> 00:06:46.680
signatures like gamma ray emissions. What makes this discovery particularly

107
00:06:46.720 --> 00:06:49.319
intriguing is that it suggests we might have been looking

108
00:06:49.360 --> 00:06:52.439
for dark matter in the wrong way. Instead of focusing

109
00:06:52.439 --> 00:06:55.680
solely on gravitational effects, we might be able to detect

110
00:06:55.800 --> 00:06:59.319
dark matter through its subtle influence on cosmic chemistry. It's

111
00:06:59.360 --> 00:07:02.000
like finding foot prints in the sand. While we can't

112
00:07:02.000 --> 00:07:04.360
see the person who made them, we can study their

113
00:07:04.399 --> 00:07:08.639
impact on the environment. The research team's calculations show that

114
00:07:08.680 --> 00:07:12.199
this lighter form of dark matter fits perfectly within existing

115
00:07:12.279 --> 00:07:16.680
constraints without contradicting other observations from gamma ray telescopes or

116
00:07:16.720 --> 00:07:20.800
the cosmic microwave background. This is remarkably rare in dark

117
00:07:20.839 --> 00:07:24.839
matter research, where proposed explanations often conflict with existing data.

118
00:07:25.800 --> 00:07:29.800
Looking ahead, NASA's upcoming COCY gamma ray telescope, scheduled for

119
00:07:29.879 --> 00:07:33.279
launch in twenty twenty seven, could provide crucial evidence to

120
00:07:33.279 --> 00:07:37.600
support or challenge this theory. If confirmed, this discovery would

121
00:07:37.600 --> 00:07:41.560
open an entirely new avenue for studying dark matter, fundamentally

122
00:07:41.639 --> 00:07:45.480
changing our approach to understanding the mysterious substance that makes

123
00:07:45.560 --> 00:07:47.920
up eighty five percent of the matter in our universe.

124
00:07:48.720 --> 00:07:52.360
This represents a potential paradigm shift in dark matter research.

125
00:07:52.879 --> 00:07:56.000
Suggesting that the key to understanding this elusive substance might

126
00:07:56.079 --> 00:07:59.480
lie not in its gravitational effects, but in its subtle

127
00:07:59.519 --> 00:08:04.040
chemical influence on the very fabric of our galaxy. In

128
00:08:04.079 --> 00:08:08.240
an important development for NASA's Artemis program, the upper stage

129
00:08:08.240 --> 00:08:11.399
for the Artemis two SLS rocket arrived at Kennedy Space

130
00:08:11.439 --> 00:08:15.079
Center on March fourth. This crucial component, known as the

131
00:08:15.120 --> 00:08:19.879
interim cryogenic propulsion stage, was delivered by Boeing and United

132
00:08:19.959 --> 00:08:24.240
Launch Alliance to the Multi Payload Processing Facility. The delivery

133
00:08:24.279 --> 00:08:27.879
marks another significant step forward in NASA's mission to return

134
00:08:27.959 --> 00:08:31.959
humans to the Moon. This four story propulsion system, powered

135
00:08:32.000 --> 00:08:35.000
by an RL ten engine, will play a vital role

136
00:08:35.039 --> 00:08:38.200
in the mission profile. After launch, it will provide the

137
00:08:38.200 --> 00:08:41.799
Orion spacecraft with the necessary thrust to complete two orbits

138
00:08:41.840 --> 00:08:44.679
around Earth before embarking on its journey to the Moon.

139
00:08:45.240 --> 00:08:48.600
Technicians at the processing facility will now begin the meticulous

140
00:08:48.639 --> 00:08:51.240
work of preparing the upper stage for integration with the

141
00:08:51.240 --> 00:08:54.360
rest of the SLS rocket. Their first task will be

142
00:08:54.399 --> 00:08:57.600
fueling the stage with hydrazine for its reaction control system.

143
00:08:58.360 --> 00:09:01.600
Once this is complete, the opponent will be transported to

144
00:09:01.639 --> 00:09:04.960
the Vehicle Assembly building, where it will be integrated with

145
00:09:05.080 --> 00:09:09.159
other elements of the rocket a top mobile launcher one.

146
00:09:09.200 --> 00:09:12.440
The assembly process is already well underway, with the solid

147
00:09:12.559 --> 00:09:15.960
rocket booster segments already in place. The core stage will

148
00:09:15.960 --> 00:09:19.200
soon be integrated, followed by the launch vehicle stage adapter.

149
00:09:19.759 --> 00:09:22.600
The upper stage will then be carefully mated to this adapter,

150
00:09:23.039 --> 00:09:26.679
bringing us one step closer to launch. This milestone delivery

151
00:09:26.799 --> 00:09:30.200
demonstrates the steady progress being made on the Artemis two mission,

152
00:09:30.519 --> 00:09:33.200
which will be the first crude mission of NASA's New

153
00:09:33.240 --> 00:09:37.559
Moon Exploration program. Each component that arrives at Kennedy Space

154
00:09:37.559 --> 00:09:40.840
Center brings us closer to the historic moment when humans

155
00:09:40.879 --> 00:09:43.960
will once again venture beyond low Earth orbit and return

156
00:09:44.000 --> 00:09:49.279
to lunar space. SpaceX has been experiencing an uncharacteristically challenging

157
00:09:49.320 --> 00:09:52.360
start to twenty twenty five, facing a series of technical

158
00:09:52.399 --> 00:09:56.320
issues despite maintaining their position as the world's leading launch provider.

159
00:09:56.759 --> 00:10:00.639
While the company continues to demonstrate remarkable launch frequency, recent

160
00:10:00.679 --> 00:10:04.720
events suggest they may be approaching their operational limits. Several

161
00:10:04.759 --> 00:10:09.399
notable incidents have raised concerns. The sphere X mission, originally

162
00:10:09.399 --> 00:10:12.399
scheduled for late February, has faced nearly two weeks of

163
00:10:12.399 --> 00:10:15.840
delays due to integration problems, though to be fair, the

164
00:10:15.919 --> 00:10:18.559
latest delay is due to weather and even SpaceX can't

165
00:10:18.600 --> 00:10:22.039
control that. More seriously, there have been issues with the

166
00:10:22.080 --> 00:10:25.519
Falcon nine's first stage, including a recent launch where a

167
00:10:25.519 --> 00:10:28.039
fuel leak led to a post landing fire that caused

168
00:10:28.039 --> 00:10:31.559
the booster to topple on the Drone ship. This marks

169
00:10:31.559 --> 00:10:34.519
the second landing failure in just six months, following a

170
00:10:34.559 --> 00:10:38.159
similar engine compartment fire last August. The company has also

171
00:10:38.240 --> 00:10:42.320
encountered recurring problems with the Falcon nine's upper stage. In

172
00:10:42.399 --> 00:10:46.159
early February, a failed de orbit burn resulted in propellant

173
00:10:46.200 --> 00:10:50.240
tanks crashing into Western Poland. While fortunately no one was harmed,

174
00:10:50.399 --> 00:10:52.960
this marked the third upper stage issue in half a year.

175
00:10:53.799 --> 00:10:58.159
Adding to these challenges, SpaceX's Starship vehicle has experienced two

176
00:10:58.279 --> 00:11:02.399
consecutive test flight failures, with both attempts ending in spectacular

177
00:11:02.480 --> 00:11:06.360
explosions over the Bahamas. However, it's important to put these

178
00:11:06.360 --> 00:11:10.480
setbacks in perspective. SpaceX maintains an impressive success rate in

179
00:11:10.519 --> 00:11:14.279
delivering payloads to orbit, with only one operational payload loss

180
00:11:14.320 --> 00:11:17.960
in nearly a decade. Their launch cadence remains unmatched globally,

181
00:11:18.320 --> 00:11:21.759
with twenty seven missions already completed this year, outpacing the

182
00:11:21.759 --> 00:11:26.240
combined total of all other launch providers worldwide. These recent

183
00:11:26.320 --> 00:11:30.360
challenges may be indicating the natural consequences of SpaceX's aggressive

184
00:11:30.440 --> 00:11:34.879
pace and ambitious goals. The company is simultaneously managing the

185
00:11:34.879 --> 00:11:40.120
world's busiest launch schedule, operating a massive satellite constellation, conducting

186
00:11:40.200 --> 00:11:43.919
human spaceflight missions, and developing the largest rocket ever built.

187
00:11:44.759 --> 00:11:49.559
This combination of high operational tempo and continuing innovation appears

188
00:11:49.600 --> 00:11:52.240
to be testing the limits of what's currently possible in

189
00:11:52.240 --> 00:11:55.759
commercial spaceflight. These growing pains come at a crucial time,

190
00:11:56.039 --> 00:11:59.480
as SpaceX remains the Western world's sole provider of human

191
00:11:59.519 --> 00:12:02.440
access to time orbit and the primary launch vehicle for

192
00:12:02.519 --> 00:12:06.960
NASA's science missions. While these recent issues haven't compromised their

193
00:12:07.000 --> 00:12:10.240
dominant position in the industry, they serve as a reminder

194
00:12:10.279 --> 00:12:13.679
that even the most successful space company must carefully balance

195
00:12:13.720 --> 00:12:18.440
speed and reliability. And that's all For today's episode of
