00:00:00.200 --> 00:00:03.439
Welcome to Astronomy Daily. I'm anna, and today we have

2
00:00:03.480 --> 00:00:06.679
an incredible lineup of stories that showcase the cutting edge

3
00:00:06.679 --> 00:00:11.039
of space exploration and astronomical discoveries. We'll dive into a

4
00:00:11.039 --> 00:00:15.119
fascinating breakthrough regarding the mysterious dark matter in our galaxy's

5
00:00:15.160 --> 00:00:19.359
GD one stellar stream, explore China's ambitious testing of multiple

6
00:00:19.399 --> 00:00:22.679
rocket engines, and catch up with NASA's Artemus one Oriyan

7
00:00:22.760 --> 00:00:26.199
spacecraft as it returns home to Kennedy Space Center. We'll

8
00:00:26.199 --> 00:00:29.359
also look at SpaceX's upcoming launch of not one, but

9
00:00:29.480 --> 00:00:33.560
two private lunar landers, and discover how NASA is developing

10
00:00:33.640 --> 00:00:37.880
new radiation resistant computers to handle the harsh environment of space.

11
00:00:38.880 --> 00:00:41.479
It's a packed show that highlights just how quickly space

12
00:00:41.520 --> 00:00:44.759
technology and our understanding of the Cosmos continue to evolve.

13
00:00:45.479 --> 00:00:48.560
So let's get started. Let's kick the news off today

14
00:00:48.600 --> 00:00:52.439
with a quick update. Blue Origin, the space venture founded

15
00:00:52.479 --> 00:00:55.759
by Jeff Bezos, has postponed the inaugural flight of its

16
00:00:55.799 --> 00:00:59.439
new Glen rocket. The launch, initially set for early Monday

17
00:00:59.479 --> 00:01:02.640
morning at CAIS sape Canaveral, faced multiple delays due to

18
00:01:02.679 --> 00:01:06.760
technical issues and unfavorable weather conditions. An icing problem in

19
00:01:06.799 --> 00:01:10.480
a purge line crucial for the rocket's hydraulic systems was

20
00:01:10.519 --> 00:01:14.439
identified during the countdown. This, combined with high seas affecting

21
00:01:14.480 --> 00:01:17.519
the booster's planned ocean landing, led to the decision to

22
00:01:17.560 --> 00:01:20.879
stand down. The company now aims for a potential launch

23
00:01:20.920 --> 00:01:23.560
on Thursday, with a three hour window starting at one

24
00:01:23.560 --> 00:01:27.359
a m Eastern time. Standing at three hundred and twenty feet,

25
00:01:27.640 --> 00:01:30.239
the new Glen rocket is named in honor of astronaut

26
00:01:30.319 --> 00:01:33.920
John Glenn. It's designed to carry heavy payloads and features

27
00:01:33.959 --> 00:01:37.959
a reusable first stage booster, marking a significant step forward

28
00:01:37.959 --> 00:01:41.359
in Blue Origin's mission to make space travel more sustainable

29
00:01:41.400 --> 00:01:45.799
and cost effective. This mission, dubbed NNG one, is set

30
00:01:45.840 --> 00:01:49.120
to carry a prototype of the Blue Ring spacecraft, intended

31
00:01:49.159 --> 00:01:52.719
for future deep space missions. A successful launch would position

32
00:01:52.760 --> 00:01:56.200
Blue Origin as a formidable competitor in the commercial space sector,

33
00:01:56.719 --> 00:02:01.200
challenging the dominance of Elon Musk's SpaceX. While the delay

34
00:02:01.319 --> 00:02:04.879
is undoubtedly a setback, it's a reminder of the complexities

35
00:02:04.879 --> 00:02:09.479
involved in space exploration. Each challenge presents an opportunity for

36
00:02:09.560 --> 00:02:14.560
growth and innovation. As Jeff Bezos himself has emphasized gratitem

37
00:02:14.639 --> 00:02:19.120
ferocit step by step ferociously will keep you updated on

38
00:02:19.159 --> 00:02:23.360
Blue origins, progress and the rescheduled launch. Astronomers may have

39
00:02:23.400 --> 00:02:26.280
finally cracked a long standing cosmic mystery about one of

40
00:02:26.280 --> 00:02:30.960
our galaxy's most intriguing features, the GD one stellar stream.

41
00:02:31.360 --> 00:02:34.319
This ribbon like structure of stars, which stretches across our

42
00:02:34.360 --> 00:02:37.759
galaxies halo, has puzzled scientists for years due to its

43
00:02:37.879 --> 00:02:41.000
unusual patterns of gaps and spurs that seem to defy

44
00:02:41.080 --> 00:02:45.400
conventional explanations. A team led by researchers at the University

45
00:02:45.400 --> 00:02:49.680
of California Riverside has proposed an exciting solution involving dark matter,

46
00:02:50.080 --> 00:02:53.360
but not just any dark matter. Their research suggests these

47
00:02:53.400 --> 00:02:57.240
distinctive features were created by what's called a self interacting

48
00:02:57.319 --> 00:03:00.919
dark matter sub halo, a dense concentration of dark matter

49
00:03:01.000 --> 00:03:04.319
that behaves differently than the traditional cold dark matter model

50
00:03:04.319 --> 00:03:09.000
we're familiar with. What makes this discovery particularly fascinating is

51
00:03:09.039 --> 00:03:12.400
that the density needed to create these unusual patterns in

52
00:03:12.479 --> 00:03:15.960
GD one is much higher than what we'd expect from

53
00:03:16.039 --> 00:03:19.560
conventional dark matter theories. The research team found that only

54
00:03:19.639 --> 00:03:23.599
a collapsing subhilo of self interacting dark matter could achieve

55
00:03:23.639 --> 00:03:27.280
the necessary density to produce these distinctive features we observe.

56
00:03:28.319 --> 00:03:32.360
This isn't just about solving one mysterious structure in our galaxy.

57
00:03:32.439 --> 00:03:36.120
If confirmed, these findings could fundamentally change our understanding of

58
00:03:36.199 --> 00:03:40.240
dark matter itself. Remember, dark matter makes up about eighty

59
00:03:40.280 --> 00:03:43.159
five percent of all matter in the universe, yet we

60
00:03:43.240 --> 00:03:47.080
still know remarkably little about its true nature. This research

61
00:03:47.120 --> 00:03:50.080
suggests that dark matter particles might interact with each other

62
00:03:50.159 --> 00:03:53.439
through a new kind of force, rather than being completely

63
00:03:53.439 --> 00:03:57.280
invisible to one another as previously thought. The team used

64
00:03:57.280 --> 00:04:00.960
sophisticated computer simulations to model how this sell interacting dark

65
00:04:01.000 --> 00:04:04.199
matter would behave, and the results matched perfectly with the

66
00:04:04.280 --> 00:04:08.280
observed features in the GD one stream. It's like finding

67
00:04:08.280 --> 00:04:10.319
the missing piece of a puzzle that's been sitting on

68
00:04:10.319 --> 00:04:13.759
the table for years, suddenly revealing a whole new picture

69
00:04:13.840 --> 00:04:17.759
of how our galaxy works. What's particularly exciting about this

70
00:04:17.839 --> 00:04:20.959
discovery is that it opens up new ways to study

71
00:04:21.040 --> 00:04:24.920
dark matter. By looking at stellar streams like GD one,

72
00:04:25.120 --> 00:04:27.439
we might be able to better understand not just where

73
00:04:27.560 --> 00:04:30.959
dark matter is, but how it behaves and interacts with itself,

74
00:04:31.839 --> 00:04:38.000
something that could revolutionize our understanding of the universe's fundamental structure. Next,

75
00:04:38.399 --> 00:04:40.879
a little mystery from China that has set the space

76
00:04:40.920 --> 00:04:45.680
community buzzing. In a remarkable display of technological advancement, China's

77
00:04:45.680 --> 00:04:49.759
space program has taken a significant leap forward, conducting tests

78
00:04:49.800 --> 00:04:52.600
of five different rocket engines all in a single day.

79
00:04:53.040 --> 00:04:57.120
The China Aerospace Science and Technology Corporation or CASSI, carried

80
00:04:57.120 --> 00:05:00.680
out these tests at two separate locations, beij and Laiwan

81
00:05:00.720 --> 00:05:04.480
County in Hebei Province. One of the most notable tests

82
00:05:04.519 --> 00:05:08.639
involved a new hydrogen oxygen engine designed for upper stage rockets.

83
00:05:09.079 --> 00:05:12.639
During its one hundred second test, firing, engineers gathered crucial

84
00:05:12.680 --> 00:05:15.720
performance data that could pave the way for future missions.

85
00:05:16.079 --> 00:05:19.560
This wasn't just any routine test. It's believed to be

86
00:05:19.600 --> 00:05:23.560
connected to China's ambitious plans for crude lunar missions, specifically

87
00:05:23.600 --> 00:05:26.800
their long March tenth launcher program. But that's not all

88
00:05:26.839 --> 00:05:30.560
that was tested that day. In Beijing, engineers put three

89
00:05:30.600 --> 00:05:34.279
different engines through their paces, a main engine, an upper

90
00:05:34.279 --> 00:05:38.199
stage engine, and a reaction in orbit control engine. While

91
00:05:38.199 --> 00:05:41.360
specific details about which rockets these engines are destined for

92
00:05:41.800 --> 00:05:45.240
remain under wraps, it's clear that China is developing multiple

93
00:05:45.319 --> 00:05:51.319
launch capabilities simultaneously. Perhaps most intriguingly, the testing day included

94
00:05:51.360 --> 00:05:55.480
a methane liquid oxygen engine at the Laiuan facility. This

95
00:05:55.639 --> 00:05:58.800
type of engine represents the cutting edge of rocket technology,

96
00:05:59.079 --> 00:06:03.360
with several Chinese companies already developing similar systems. It's worth

97
00:06:03.399 --> 00:06:06.560
noting that Cassie is working on a particularly powerful version

98
00:06:07.079 --> 00:06:10.920
for their long March ninth Mega rocket project. These tests

99
00:06:10.959 --> 00:06:14.959
signal China's commitment to developing a diverse range of rocket technologies,

100
00:06:15.319 --> 00:06:19.680
from deep space exploration vehicles to heavy lift rockets. According

101
00:06:19.680 --> 00:06:22.720
to KSC engineers, this is just the beginning. They're planning

102
00:06:22.800 --> 00:06:25.600
to conduct even more research and testing of various engine

103
00:06:25.639 --> 00:06:29.079
types for China's major space projects, suggesting we might see

104
00:06:29.120 --> 00:06:32.800
several new Chinese rockets debut in the coming year. This

105
00:06:32.920 --> 00:06:37.560
coordinated testing effort demonstrates China's growing capabilities in space technology

106
00:06:37.959 --> 00:06:41.399
and their determination to become a major player in space exploration.

107
00:06:42.120 --> 00:06:45.600
With these successful tests, they're laying the groundwork for increasingly

108
00:06:45.639 --> 00:06:52.120
ambitious missions, from lunar exploration to potential Mars voyages. Meanwhile,

109
00:06:52.399 --> 00:06:55.680
back in the States, the Artemis Ones Orion spacecraft has

110
00:06:55.680 --> 00:06:58.560
made its way back to Kennedy Space Center after completing

111
00:06:58.560 --> 00:07:03.199
an extensive eleven month testing campaign in Ohio. Now designated

112
00:07:03.199 --> 00:07:07.480
as the Orion Environmental Test Article or ETA, this spacecraft

113
00:07:07.519 --> 00:07:09.879
has already proven its worth during its historic journey around

114
00:07:09.879 --> 00:07:12.839
the Moon, but its mission to advance space exploration is

115
00:07:12.879 --> 00:07:16.519
far from over. After splashing down in the Pacific Ocean

116
00:07:16.560 --> 00:07:20.399
following its lunar adventure, the spacecraft was transported across the

117
00:07:20.399 --> 00:07:24.319
country to Florida, where it underwent its first round of modifications.

118
00:07:24.839 --> 00:07:28.639
But it was at NASA's Neil Armstrong Test Facility in Sandusky, Ohio,

119
00:07:29.000 --> 00:07:32.120
where the real intensive testing took place, preparing it for

120
00:07:32.199 --> 00:07:36.160
even more challenging future missions. Now back at Kennedy's Multi

121
00:07:36.199 --> 00:07:39.879
Payload Processing Facility, engineers are gearing up for a crucial

122
00:07:39.920 --> 00:07:44.199
series of tests focusing on the spacecraft's propulsion systems. Of

123
00:07:44.279 --> 00:07:48.439
particular interest are the twelve reaction control system thrusters, which

124
00:07:48.480 --> 00:07:53.120
will undergo simulated hot fire testing. These thrusters are absolutely

125
00:07:53.240 --> 00:07:57.160
vital for controlling the spacecraft's rotation during orbit, re entry,

126
00:07:57.560 --> 00:08:01.600
and potential abort scenarios. But the testing doesn't stop there.

127
00:08:02.199 --> 00:08:04.639
The spacecraft will soon make its way to Kennedy's Space

128
00:08:04.639 --> 00:08:10.160
system's processing facility for acoustic noise demonstration tests. These evaluations

129
00:08:10.199 --> 00:08:14.399
are crucial for improving future acoustic testing procedures, benefiting both

130
00:08:14.519 --> 00:08:19.959
NASA and their primary contractor, Lockheed Martin. Perhaps most intriguingly,

131
00:08:20.360 --> 00:08:23.519
teams will be carefully removing certain pieces of hardware from

132
00:08:23.519 --> 00:08:27.720
the ETA for reusability studies. The knowledge gained from examining

133
00:08:27.759 --> 00:08:31.519
these components could prove invaluable for future Artemis missions as

134
00:08:31.639 --> 00:08:35.440
NASA continues its ambitious plans to establish a sustainable human

135
00:08:35.480 --> 00:08:39.519
presence on the Moon and eventually venture to Mars. This

136
00:08:39.639 --> 00:08:44.720
methodical testing and evaluation process demonstrates NASA's commitment to ensuring

137
00:08:44.759 --> 00:08:49.200
the safety and success of future deep space missions and

138
00:08:49.279 --> 00:08:51.919
not to be left behind. In an exciting development for

139
00:08:52.000 --> 00:08:56.159
lunar exploration, SpaceX is preparing to launch two private lunar

140
00:08:56.240 --> 00:08:59.360
landers aboard a single Falcon nine rocket from NASA's Kennedy

141
00:08:59.399 --> 00:09:02.679
Space Center. The launch window opens early Wednesday morning at

142
00:09:02.759 --> 00:09:05.600
one eleven a m Eastern time, marking what promises to

143
00:09:05.639 --> 00:09:08.159
be a busy year of missions to the Moon. The

144
00:09:08.200 --> 00:09:11.480
two spacecraft sharing this historic ride are Firefly Aerospace's Blue

145
00:09:11.519 --> 00:09:15.440
Ghost Mission IE and IE space is Resilience lander. Blue Ghost,

146
00:09:15.480 --> 00:09:18.919
part of NASA's Commercial Lunar Payload Services program, will carry

147
00:09:18.960 --> 00:09:22.799
scientific instruments to the lunar surface, while Resilience represents IE

148
00:09:22.799 --> 00:09:26.759
space's second attempt at achieving a successful moon landing. These

149
00:09:26.759 --> 00:09:30.240
missions will follow distinctly different trajectories. After separation from the

150
00:09:30.240 --> 00:09:33.360
Falcon nine, blue Ghost will spend about twenty five days

151
00:09:33.360 --> 00:09:35.960
in Earth orbit before initiating its journey to the Moon.

152
00:09:36.399 --> 00:09:39.919
After another twenty days, including four days of transit and

153
00:09:40.000 --> 00:09:43.200
sixteen days in lunar orbit, it will attempt to touch

154
00:09:43.240 --> 00:09:47.600
down in Merrichrisium, the Sea of Crises. Once on the surface,

155
00:09:48.120 --> 00:09:51.879
it will conduct two weeks of scientific operations before capturing

156
00:09:52.000 --> 00:09:56.720
one final dramatic image of the lunar sunset. Resilience, on

157
00:09:56.759 --> 00:09:59.360
the other hand, will take a more gradual approach, spending

158
00:09:59.399 --> 00:10:04.080
four to five months reaching its destination. This extended timeline

159
00:10:04.120 --> 00:10:08.120
reflects lessons learned from Icepace's first mission, which reached lunar

160
00:10:08.240 --> 00:10:12.000
orbit but unfortunately crashed during its landing attempt last April.

161
00:10:12.120 --> 00:10:15.799
The spacecraft features significant upgrades to both hardware and software,

162
00:10:16.120 --> 00:10:19.639
aiming to succeed where its predecessor fell short. The mission's

163
00:10:19.639 --> 00:10:22.799
target is Mare Frigoris, the Sea of Cold in the

164
00:10:22.799 --> 00:10:26.559
Moon's northern hemisphere. There, it will deploy a small rover

165
00:10:26.639 --> 00:10:29.759
named Tenacius, which will collect lunar dust samples as part

166
00:10:29.799 --> 00:10:34.799
of a NASA contract. This careful, milestone based approach demonstrates

167
00:10:34.799 --> 00:10:38.559
I Space's commitment to achieving the first successful private Japanese

168
00:10:38.639 --> 00:10:41.840
landing on the Moon. These launches kick off what promises

169
00:10:41.840 --> 00:10:45.879
to be an extraordinarily active year for lunar exploration, with

170
00:10:46.000 --> 00:10:49.960
multiple missions planned by various companies and space agencies. From

171
00:10:50.039 --> 00:10:54.200
Intuitive Machines upcoming IM two mission to Blue Origins development

172
00:10:54.279 --> 00:10:57.120
of their lunar lander. We're witnessing the dawn of a

173
00:10:57.159 --> 00:11:02.360
new era in commercial lunar exploration. Computers have become absolutely

174
00:11:02.480 --> 00:11:06.080
essential for space exploration, but they face a serious challenge

175
00:11:06.080 --> 00:11:09.159
that we don't have to worry about here on Earth. Radiation.

176
00:11:10.159 --> 00:11:13.600
While our planet's magnetic field and atmosphere protect our electronics

177
00:11:13.600 --> 00:11:16.919
from harmful radiation, spacecraft computers have to cope with direct

178
00:11:16.960 --> 00:11:20.600
exposure to high energy particles from the Sun and cosmic rays.

179
00:11:20.960 --> 00:11:23.679
The effects can be severe. Even a single blast of

180
00:11:23.759 --> 00:11:26.960
radiation can cause what scientists call a single event effect,

181
00:11:27.320 --> 00:11:31.039
potentially corrupting data or causing system crashes that could jeopardize

182
00:11:31.159 --> 00:11:35.200
entire missions. That's why NASA is now testing an innovative solution,

183
00:11:35.720 --> 00:11:40.679
the Radiation Tolerant Computer, or RATYPC for short. This remarkable

184
00:11:40.720 --> 00:11:43.279
piece of technology is scheduled for its first real world

185
00:11:43.320 --> 00:11:46.879
test aboard the upcoming Blue Ghost lunar mission. What makes

186
00:11:46.879 --> 00:11:49.519
the rad PC special is its ability to monitor and

187
00:11:49.600 --> 00:11:53.200
repair itself in real time. It uses special processors called

188
00:11:53.240 --> 00:11:56.279
programmable gait arrays that can detect when they've been struck

189
00:11:56.320 --> 00:12:01.360
by radiation and automatically fix any damage without interrupting normal operations.

190
00:12:02.080 --> 00:12:06.480
The system also includes radiation sensors or docimeters that will

191
00:12:06.480 --> 00:12:09.679
continuously measure radiation levels during the journey to the moon.

192
00:12:10.320 --> 00:12:14.080
This will provide valuable data about how radiation levels change

193
00:12:14.120 --> 00:12:18.240
as spacecraft move through Earth's magnetosphere and into deep space,

194
00:12:18.679 --> 00:12:21.879
as well as detailed information about radiation conditions at the

195
00:12:22.000 --> 00:12:27.279
landing site. If successful, the rad PC could revolutionize space computing.

196
00:12:27.840 --> 00:12:31.320
Its self healing capabilities could make future spacecraft computers far

197
00:12:31.399 --> 00:12:35.320
more resilient and reliable, especially for long duration missions where

198
00:12:35.399 --> 00:12:39.519
radiation exposure is inevitable. This kind of advancement is crucial

199
00:12:39.559 --> 00:12:42.960
as we push further into space, whether it's establishing a

200
00:12:43.000 --> 00:12:46.919
permanent presence on the Moon or eventually sending humans to Mars.

201
00:12:49.000 --> 00:12:51.799
