00:00:00.200 --> 00:00:02.919
Welcome to Astronomy Daily, your source for the latest space

2
00:00:02.919 --> 00:00:05.719
in astronomy news. Today, we have an exciting lineup of

3
00:00:05.759 --> 00:00:08.400
stories from across the space industry. We'll look at a

4
00:00:08.439 --> 00:00:11.400
mysterious SpaceX mission that was scrubbed at the last minute

5
00:00:11.560 --> 00:00:15.480
that's generating buzz in the space community, explore China's ambitious

6
00:00:15.480 --> 00:00:19.399
new satellite constellation project, and dive into NASA's latest plans

7
00:00:19.399 --> 00:00:22.960
for getting humans from the Moon to Mars. Plus, we'll

8
00:00:23.000 --> 00:00:26.519
examine fascinating new research about the possibility of Moon's orbiting

9
00:00:26.559 --> 00:00:29.839
planets around binary star systems, and more. There's a lot

10
00:00:29.839 --> 00:00:33.920
to cover, so let's get started. SpaceX has once again

11
00:00:33.960 --> 00:00:37.640
captured the space community's attention, this time with their enigmatic

12
00:00:37.880 --> 00:00:41.359
RT one mission from Florida's Cape Canaveral Space Force Station.

13
00:00:42.240 --> 00:00:45.079
While the launch was ultimately scrubbed due to high winds,

14
00:00:45.520 --> 00:00:49.079
it's the mysterious nature of the payload that has everyone talking.

15
00:00:50.039 --> 00:00:53.679
The mission details are unusually sparse, even by SpaceX standards.

16
00:00:54.280 --> 00:00:57.560
While many space observers believe RRT one will carry an

17
00:00:57.600 --> 00:01:03.359
advanced GPS satellite, specifically GPS three ten, SpaceX has remained

18
00:01:03.439 --> 00:01:06.879
tight lipped about the payload. The company hasn't even explained

19
00:01:06.959 --> 00:01:10.319
what the rrt IE designation means if it's an acronym

20
00:01:10.319 --> 00:01:14.280
at all. Adding to the intrigue, the payload faring that's

21
00:01:14.319 --> 00:01:17.680
the nose cone that protects the satellite during launch, lacks

22
00:01:17.719 --> 00:01:20.439
any of the usual artwork or logos we typically see

23
00:01:20.480 --> 00:01:24.840
on SpaceX missions. This departure from normal practices has only

24
00:01:24.840 --> 00:01:28.439
fueled more speculation about the mission's true nature. When the

25
00:01:28.519 --> 00:01:31.840
launch does proceed, the plan calls for the Falcon nine's

26
00:01:31.920 --> 00:01:34.280
first stage to return for a landing on the Drone

27
00:01:34.280 --> 00:01:37.400
ship a short fall of gravitas in the Atlantic Ocean

28
00:01:37.760 --> 00:01:40.879
about eight and a half minutes after liftoff. The booster

29
00:01:41.000 --> 00:01:44.079
isn't new to spaceflight, this will be its fourth mission.

30
00:01:44.519 --> 00:01:47.920
As for the payload, it's scheduled for deployment into orbit

31
00:01:47.959 --> 00:01:52.519
approximately ninety minutes after launch, though exactly what orbit remains

32
00:01:52.560 --> 00:01:57.159
another piece of this intriguing puzzle. Meanwhile, on the other

33
00:01:57.200 --> 00:02:00.359
side of the world, in a significant development for China

34
00:02:00.400 --> 00:02:04.239
space program, a long March two D rocket successfully launched

35
00:02:04.280 --> 00:02:07.680
five new satellites early Thursday morning from the Juquan Satellite

36
00:02:07.760 --> 00:02:11.360
Launch Center. These satellites form what's being called the High

37
00:02:11.360 --> 00:02:15.840
Speed Laser Diamond Constellation test system, marking an important step

38
00:02:15.879 --> 00:02:19.719
forward in China's space capabilities. The launch utilized a Yunjang

39
00:02:19.759 --> 00:02:24.000
three restartable upper stage to precisely position the satellites in

40
00:02:24.080 --> 00:02:28.680
three distinct orbits. Space tracking has confirmed that one satellite

41
00:02:28.719 --> 00:02:32.199
now occupies an orbit between nine hundred and eighty eight

42
00:02:32.639 --> 00:02:36.680
and one thousand, one hundred and sixty kilometers, another sits

43
00:02:36.719 --> 00:02:39.599
between seven hundred and ninety one and eight hundred and

44
00:02:39.639 --> 00:02:43.879
twelve kilometers, while the remaining three orbit at approximately nine

45
00:02:43.919 --> 00:02:47.800
hundred seventy five to nine hundred ninety kilometers above Earth.

46
00:02:48.840 --> 00:02:52.960
While specific details about the satellites remain limited, their designation

47
00:02:53.120 --> 00:02:58.439
suggests their designed to test advanced inter satellite laser communication links.

48
00:02:58.800 --> 00:03:03.520
This technology could prove crucial for China's ambitious mega constellation projects,

49
00:03:03.560 --> 00:03:07.759
including their National Gang constellation and the Shanghai backed Chanfan

50
00:03:08.319 --> 00:03:12.560
also known as the Thousand Sales constellation. This laser communication

51
00:03:12.639 --> 00:03:16.439
capability could help address one of China's key space challenges,

52
00:03:16.800 --> 00:03:20.439
their limited global ground station coverage. By enabling satellites to

53
00:03:20.439 --> 00:03:23.759
communicate directly with each other using laser links, they could

54
00:03:23.759 --> 00:03:29.000
significantly improve their network's effectiveness and reduce reliance on ground stations.

55
00:03:29.840 --> 00:03:33.319
This launch marks China's sixty third orbital launch attempt of

56
00:03:33.400 --> 00:03:36.879
twenty twenty four, putting them on track to potentially surpass

57
00:03:36.919 --> 00:03:40.800
their national record of sixty seven launches set just last year.

58
00:03:41.639 --> 00:03:45.080
With several more launches scheduled before year's end, including what

59
00:03:45.159 --> 00:03:49.280
could be the first Guwang Mega constellation satellites, China continues

60
00:03:49.319 --> 00:03:53.960
to demonstrate its growing prominence in space exploration and technology development.

61
00:03:55.520 --> 00:03:58.319
NASA has just released a comprehensive update to their Moon

62
00:03:58.360 --> 00:04:02.439
to Mars architecture, providing fresh insights into their ambitious plans

63
00:04:02.479 --> 00:04:06.479
for deep space exploration. The new documents outline a methodical

64
00:04:06.479 --> 00:04:09.759
approach to establishing a sustained human presence on the Moon

65
00:04:10.280 --> 00:04:13.680
while preparing for the ultimate goal of sending astronauts to Mars.

66
00:04:14.560 --> 00:04:18.000
One of the most notable revelations is NASA's decision to

67
00:04:18.120 --> 00:04:21.600
use nuclear fission as the primary power source for future

68
00:04:21.600 --> 00:04:25.399
Mars missions. This choice makes perfect sense given the challenging

69
00:04:25.439 --> 00:04:29.920
Martian environment. Unlike solar power, nuclear fission won't be affected

70
00:04:29.920 --> 00:04:32.759
by the planet's dust storms or the day night cycle,

71
00:04:33.079 --> 00:04:37.879
providing reliable, consistent energy for long term operations. The agency

72
00:04:37.920 --> 00:04:41.000
has also added two crucial new elements to their lunar

73
00:04:41.040 --> 00:04:46.000
infrastructure plans. First, they're developing a dedicated lunar surface cargo

74
00:04:46.120 --> 00:04:51.160
lander designed to deliver essential supplies, scientific equipment, and communication

75
00:04:51.279 --> 00:04:55.439
systems to the Moon. Second, they're planning and initial lunar

76
00:04:55.439 --> 00:04:58.040
surface habitat that will enable larger crews to stay on

77
00:04:58.079 --> 00:05:02.199
the Moon for extended periods, significantly expanding our capabilities for

78
00:05:02.279 --> 00:05:07.639
lunar exploration and research. These updates reflect NASA's careful, staged

79
00:05:07.680 --> 00:05:11.079
approach to deep space exploration. They're not just rushing to

80
00:05:11.120 --> 00:05:14.720
plant flags, they're building the foundation for permanent human presence

81
00:05:14.800 --> 00:05:18.879
beyond Earth. The agency is working closely with industry partners,

82
00:05:19.160 --> 00:05:23.639
academic institutions, and international collaborators to ensure their plans are

83
00:05:23.639 --> 00:05:28.160
both ambitious and achievable. This methodical planning process includes a

84
00:05:28.199 --> 00:05:31.639
new prioritized list of key architecture decisions that need to

85
00:05:31.639 --> 00:05:34.399
be made early in the planning stages for Mars missions.

86
00:05:35.240 --> 00:05:39.160
By identifying these critical decision points now, NASA can better

87
00:05:39.199 --> 00:05:43.279
coordinate its technology development efforts and ensure their investing resources

88
00:05:43.319 --> 00:05:47.720
in the most important areas for future mission success. In

89
00:05:47.759 --> 00:05:52.160
an exciting development from Tufft's University researchers have been investigating

90
00:05:52.199 --> 00:05:55.680
whether moons could exist around planets that orbit two stars.

91
00:05:56.199 --> 00:05:59.959
This groundbreaking study addresses a fascinating question about the complex,

92
00:06:00.000 --> 00:06:03.839
exity and diversity of planetary systems beyond our solar system.

93
00:06:04.399 --> 00:06:07.959
The research team used advanced computer simulations to model how

94
00:06:07.959 --> 00:06:12.079
exo moons might orbit what we call circumbinary planets, planets

95
00:06:12.160 --> 00:06:15.519
that circle two stars instead of one. What makes this

96
00:06:15.560 --> 00:06:19.199
particularly intriguing is that these binary star systems might actually

97
00:06:19.199 --> 00:06:24.439
offer more opportunities for potentially habitable worlds than we previously thought.

98
00:06:24.720 --> 00:06:28.160
Their simulations revealed that thirty to forty percent of stable

99
00:06:28.199 --> 00:06:31.079
moons in these systems could exist within the habitable zone,

100
00:06:31.519 --> 00:06:34.439
that sweet spot where conditions might be right for liquid

101
00:06:34.480 --> 00:06:38.240
water to exist on a surface. This is particularly significant

102
00:06:38.279 --> 00:06:41.680
because while many circumbinary planets we've discovered are gas giants,

103
00:06:42.120 --> 00:06:46.160
their moons could be Earth sized and potentially suitable for life.

104
00:06:46.240 --> 00:06:49.560
The study found that there are indeed stable orbits where

105
00:06:49.600 --> 00:06:53.399
moons could exist in these complex systems. This stability is

106
00:06:53.439 --> 00:06:57.000
crucial because it means these moons could persist long enough

107
00:06:57.000 --> 00:07:01.319
for life to potentially develop. The research specifically looked at

108
00:07:01.360 --> 00:07:06.319
different planetary configurations and determined what they call the hill radius,

109
00:07:07.160 --> 00:07:10.879
essentially the gravitational sphere of influence where a planet could

110
00:07:10.959 --> 00:07:14.600
keep its moons in stable orbits. While we haven't yet

111
00:07:14.639 --> 00:07:18.680
confirmed the existence of any exa moons, this research suggests

112
00:07:18.839 --> 00:07:22.399
that binary star systems might be promising places to look

113
00:07:22.439 --> 00:07:26.160
for them. The study also indicates that the best candidates

114
00:07:26.160 --> 00:07:29.040
for finding these moons would be systems where the two

115
00:07:29.079 --> 00:07:33.199
stars are widely separated, as this provides more stable conditions

116
00:07:33.240 --> 00:07:37.399
for both planets and their potential moons. Here's something to

117
00:07:37.399 --> 00:07:40.800
look forward to Early next year, NASA is gearing up

118
00:07:40.800 --> 00:07:43.680
for an exciting new mission to study our Sun. The

119
00:07:43.720 --> 00:07:47.120
PUNCH mission, which stands for Polarimeter to Unify the Corona

120
00:07:47.120 --> 00:07:50.600
and Heliosphere, is scheduled for launch in February twenty twenty

121
00:07:50.639 --> 00:07:54.040
five aboard a SpaceX Falcon nine rocket from Vandenberg Space

122
00:07:54.079 --> 00:07:58.240
Force Space. This innovative project will deploy four small satellites

123
00:07:58.279 --> 00:08:01.800
working together to capture unprecedented three D views of the

124
00:08:01.839 --> 00:08:05.240
Sun's corona and study how it transforms into the solar wind.

125
00:08:05.800 --> 00:08:09.199
The mission represents a significant step forward in our understanding

126
00:08:09.240 --> 00:08:12.079
of solar activity and space weather. With teams from the

127
00:08:12.120 --> 00:08:15.560
Southwest Research Institute leading the charge from both San Antonio

128
00:08:15.680 --> 00:08:19.079
and Boulder. Punch won't be traveling alone. It's hitching a

129
00:08:19.160 --> 00:08:23.040
ride alongside NASA's a SPHEREx observatory, making efficient use of

130
00:08:23.040 --> 00:08:27.439
the launch vehicle. Meanwhile, Virgin Galactic is expanding its horizons

131
00:08:27.439 --> 00:08:30.800
beyond US borders. The company has signed a promising agreement

132
00:08:30.839 --> 00:08:34.799
with Italy's Civil Aviation Authority to explore operating their suborbital

133
00:08:34.799 --> 00:08:38.879
space planes from Grottagli Airport in southern Italy. This collaboration

134
00:08:39.000 --> 00:08:43.159
marks a significant step toward establishing Virgin Galactic's first spaceport

135
00:08:43.200 --> 00:08:46.919
outside the United States. The project will unfold in two phases,

136
00:08:47.240 --> 00:08:50.919
with the first phase focusing on technical and operational requirements

137
00:08:51.200 --> 00:08:55.639
through twenty twenty five. This includes evaluating everything from potential

138
00:08:55.639 --> 00:08:59.879
flight paths to infrastructure needs. The Italian government has our

139
00:09:00.000 --> 00:09:04.200
already shown their commitment by allocating seventy million euros for

140
00:09:04.279 --> 00:09:08.919
spaceport infrastructure development. While actual flights from Italy are still

141
00:09:08.960 --> 00:09:13.440
several years away, Virgin Galactic isn't slowing down. They're currently

142
00:09:13.440 --> 00:09:17.639
focused on building their Delta class space planes, with assembly

143
00:09:17.840 --> 00:09:20.720
of the first vehicle scheduled to begin in early twenty

144
00:09:20.799 --> 00:09:24.679
twenty five at their new Phoenix facility. This expansion into

145
00:09:24.679 --> 00:09:28.200
Italy represents an exciting step toward making space tourism truly

146
00:09:28.240 --> 00:09:33.120
global and now a great example of astronaut ingenuity at

147
00:09:33.120 --> 00:09:36.639
work from the depths of space. Aboard the International Space Station,

148
00:09:37.320 --> 00:09:40.919
NASA astronaut Don Pettit has taken space photography to new

149
00:09:40.960 --> 00:09:45.000
heights with an innovative solution to a complex problem. Using

150
00:09:45.000 --> 00:09:48.799
his engineering expertise, Pettit created a homemade star tracker that's

151
00:09:48.799 --> 00:09:52.120
allowing him to capture breathtaking images of the Cosmos like

152
00:09:52.279 --> 00:09:56.000
never before. When you're orbiting Earth at seventeen thoy five

153
00:09:56.080 --> 00:09:59.759
hundred miles per hour, taking clear photos of stars typically

154
00:09:59.840 --> 00:10:04.240
was results in streaky, blurred images, but Pettit's ingenious device

155
00:10:04.360 --> 00:10:08.480
rotates the camera to match the ISS's ninety minute orbital period,

156
00:10:08.960 --> 00:10:13.000
compensating for the station's rapid movement. This allows for longer

157
00:10:13.039 --> 00:10:17.519
exposure times, revealing countless stars and celestial objects that would

158
00:10:17.559 --> 00:10:20.840
otherwise be impossible to photograph clearly from the space station.

159
00:10:21.919 --> 00:10:25.919
The results are spectacular, crystal clear images showing thousands of

160
00:10:25.960 --> 00:10:29.480
stars against the backdrop of Earth with our planet's distinct

161
00:10:29.519 --> 00:10:34.200
orange atmospheric glow, providing a stunning contrast. While the Earth

162
00:10:34.200 --> 00:10:37.759
appears intentionally blurred in these long exposures, the stars remain

163
00:10:37.840 --> 00:10:41.679
perfectly focused, offering an unprecedented view of the Cosmos from

164
00:10:41.720 --> 00:10:46.159
our orbital outpost. This isn't Pettit's first innovation aboard the ISS.

165
00:10:46.840 --> 00:10:50.200
During his previous stays, he invented the zero G coffee cup,

166
00:10:50.440 --> 00:10:54.720
which became the first patented invention in space. That creation

167
00:10:54.960 --> 00:10:58.720
solved the seemingly simple but technically challenging problem of drinking

168
00:10:58.799 --> 00:11:03.080
beverages normally in microgravity, rather than through pouches and straws.

169
00:11:04.159 --> 00:11:08.679
His latest photographic innovation continues this tradition of creative problem solving,

170
00:11:09.159 --> 00:11:12.759
pushing the boundaries of what's possible in space photography and

171
00:11:12.840 --> 00:11:16.840
demonstrating how astronaut ingenuity can advance our ability to document

172
00:11:16.960 --> 00:11:21.480
and study the universe around us. Well, that's all for

173
