00:00:00.160 --> 00:00:03.160
Welcome to Astronomy Daily. I'm excited to bring you another

2
00:00:03.240 --> 00:00:07.440
packed episode of fascinating space and astronomy news. Today's lineup

3
00:00:07.480 --> 00:00:12.279
features some truly groundbreaking developments that showcase humanity's continued innovation

4
00:00:12.400 --> 00:00:16.399
in space exploration. We'll start with Japan's remarkable achievement in

5
00:00:16.480 --> 00:00:20.719
launching the world's first wooden satellite. Yes you heard that right, Wooden.

6
00:00:21.559 --> 00:00:24.519
Then we'll explore Russia's latest record breaking launch that sent

7
00:00:24.600 --> 00:00:28.039
dozens of satellites into orbit in a single mission. We'll

8
00:00:28.039 --> 00:00:30.640
also take a look at an impressive new lunar vehicle

9
00:00:30.679 --> 00:00:34.520
that's pushing the boundaries of Moon exploration, followed by compelling

10
00:00:34.560 --> 00:00:37.520
new evidence of ancient oceans on Mars that could reshape

11
00:00:37.520 --> 00:00:41.240
our understanding of the red planet's history. Finally, we'll clear

12
00:00:41.320 --> 00:00:44.520
up some recent speculation about life aboard the International Space

13
00:00:44.560 --> 00:00:48.640
Station and share the latest official updates from NASA. It's

14
00:00:48.679 --> 00:00:52.439
a show that spans from innovative space technology to potential

15
00:00:52.479 --> 00:00:56.960
signs of ancient water on Mars, so let's dive right in.

16
00:00:56.960 --> 00:01:01.119
In a groundbreaking development addressing the growing concern of space debris,

17
00:01:01.600 --> 00:01:05.319
researchers from the University of Kyoto have successfully launched the

18
00:01:05.319 --> 00:01:09.519
world's first wooden satellite into orbit. The innovative Lingo SAT,

19
00:01:09.959 --> 00:01:13.359
carried aboard a SpaceX Falcon nine rocket from NASA's Kennedy

20
00:01:13.400 --> 00:01:18.000
Space Center, marks a significant step forward in sustainable space technology.

21
00:01:18.560 --> 00:01:21.840
What makes this satellite truly unique is its construction material,

22
00:01:22.079 --> 00:01:26.319
Magnolia wood. Apart from its essential electronic components, the entire

23
00:01:26.359 --> 00:01:30.120
satellite structure is wooden, representing a radical departure from traditional

24
00:01:30.120 --> 00:01:33.439
satellite design. At just ten centimeters on each side and

25
00:01:33.439 --> 00:01:36.000
weighing a mere nine hundred grams, it's one of the

26
00:01:36.079 --> 00:01:40.719
lightest satellites ever launched into space. This innovative approach tackles

27
00:01:40.760 --> 00:01:44.719
a pressing issue in space exploration. Currently, there are over

28
00:01:44.840 --> 00:01:49.280
forty thousand, five hundred objects larger than ten centimeters orbiting Earth,

29
00:01:49.799 --> 00:01:53.920
with millions more smaller pieces cluttering our orbital space. When

30
00:01:53.959 --> 00:01:57.640
traditional satellites re enter Earth's atmosphere, they can release potentially

31
00:01:57.719 --> 00:02:01.920
harmful metal particles. Then Ingo Sat, however, is designed to

32
00:02:02.000 --> 00:02:06.079
completely burn up upon re entry, leaving no harmful debris behind.

33
00:02:06.640 --> 00:02:09.840
The satellite will soon be transported to the International Space Station,

34
00:02:10.319 --> 00:02:13.159
where it will be deployed from the Kebo Japanese Experiment

35
00:02:13.280 --> 00:02:17.759
Module Over the next six months, researchers will closely monitor

36
00:02:17.800 --> 00:02:20.800
how the wooden structure holds up against the extreme conditions

37
00:02:20.840 --> 00:02:26.280
of space, including dramatic temperature fluctuations and intense radiation. This

38
00:02:26.360 --> 00:02:31.039
mission could revolutionize satellite construction. If successful, it could pave

39
00:02:31.080 --> 00:02:34.719
the way for more environmentally conscious space exploration, helping to

40
00:02:34.719 --> 00:02:38.919
prevent what scientists call Kessler syndrome, a theoretical scenario where

41
00:02:38.960 --> 00:02:41.680
the density of objects in low Earth orbit becomes so

42
00:02:41.879 --> 00:02:46.439
high that collisions cascade, creating more debris and potentially rendering

43
00:02:46.479 --> 00:02:51.199
parts of Earth's orbit unusable. A second wooden satellite, Lingosat two,

44
00:02:51.520 --> 00:02:54.560
is already planned for launch in twenty twenty six, showing

45
00:02:54.639 --> 00:02:59.439
Japan's commitment to this innovative approach to space sustainability. Next up,

46
00:02:59.639 --> 00:03:02.800
Russia has achieved a remarkable milestone in its space program,

47
00:03:03.159 --> 00:03:06.199
launching an impressive array of fifty three satellites in a

48
00:03:06.240 --> 00:03:10.360
single mission from the Vostokni spaceport in Russia's far East.

49
00:03:10.680 --> 00:03:13.479
This launch represents a national record for Russia in terms

50
00:03:13.520 --> 00:03:16.479
of the number of domestic satellites deployed in a single mission,

51
00:03:16.879 --> 00:03:20.039
with fifty one of the payloads being Russian made. The

52
00:03:20.039 --> 00:03:23.360
mission utilized a Soyuz Dash two Dot one B carrier

53
00:03:23.479 --> 00:03:27.759
rocket equipped with a frigate upper stage, demonstrating Russia's continued

54
00:03:27.759 --> 00:03:32.400
capabilities in space launch technology. Among the diverse payload were

55
00:03:32.400 --> 00:03:37.199
two Ionosphera M satellites, each weighing four hundred and thirty kilograms,

56
00:03:37.719 --> 00:03:42.280
designed to monitor Earth's ionosphere, providing valuable data for atmospheric

57
00:03:42.319 --> 00:03:47.280
research and communications. What makes this launch particularly noteworthy is

58
00:03:47.319 --> 00:03:52.680
its international character. Despite current geopolitical challenges, the mission included

59
00:03:52.719 --> 00:03:56.919
collaborative projects with multiple nations. A Russian Chinese satellite, a

60
00:03:57.000 --> 00:04:00.719
Russian Zimbabwean satellite, and two Iranian satellites were part of

61
00:04:00.759 --> 00:04:06.319
the payload, highlighting ongoing international cooperation in space exploration. The

62
00:04:06.360 --> 00:04:10.680
Iranian contributions included the Kawsar high resolution imaging satellite and

63
00:04:10.759 --> 00:04:14.919
the HADHD communication satellite. While this launch marks a significant

64
00:04:14.960 --> 00:04:18.439
achievement for Russia, it's worth noting that the global landscape

65
00:04:18.480 --> 00:04:23.079
of space launches has evolved considerably over the past decade. Russia,

66
00:04:23.399 --> 00:04:26.519
once the world's leading launch provider, now ranks third in

67
00:04:26.600 --> 00:04:31.399
launch frequency, behind the United States and China. Nevertheless, Russia

68
00:04:31.439 --> 00:04:35.439
maintains its important role in space exploration, continuing to support

69
00:04:35.480 --> 00:04:39.480
the International Space Station through regular progress resupply missions and

70
00:04:39.560 --> 00:04:44.759
Soyu's crew launches. This successful mission not only demonstrates Russia's

71
00:04:44.800 --> 00:04:48.879
technical capabilities, but also shows how space exploration continues to

72
00:04:48.920 --> 00:04:54.120
bridge international divides, fostering collaboration even during challenging times on Earth.

73
00:04:54.959 --> 00:04:59.079
The variety of satellites deployed will serve multiple purposes, from

74
00:04:59.199 --> 00:05:03.959
Earth observation to communications, contributing to both scientific research and

75
00:05:04.040 --> 00:05:08.920
practical applications in space technology. Talking of technology, I think

76
00:05:08.920 --> 00:05:12.160
I want one of these. A fascinating development in lunar

77
00:05:12.160 --> 00:05:15.920
exploration has just been unveiled in Houston, where Intuitive Machines

78
00:05:15.959 --> 00:05:19.800
has revealed their next generation lunar terrain vehicle called moon Racer.

79
00:05:20.600 --> 00:05:24.639
This reusable, autonomous crude exploration rover represents a significant leap

80
00:05:24.680 --> 00:05:28.600
forward from the Apollo era moonbuggies, combining modern technology with

81
00:05:28.680 --> 00:05:33.360
practical design. The fully electric vehicle, built in collaboration with

82
00:05:33.439 --> 00:05:37.560
high performance automotive company Rausch, is an impressive piece of engineering.

83
00:05:38.199 --> 00:05:41.639
Measuring fourteen feet long, eight point five feet tall, and

84
00:05:41.680 --> 00:05:44.560
twelve feet wide, this rover can reach speeds up to

85
00:05:44.680 --> 00:05:49.439
nine point three miles per hour, matching its Apollo predecessor's capabilities,

86
00:05:50.279 --> 00:05:54.560
but what sets it apart is its enhanced functionality, including

87
00:05:54.600 --> 00:05:57.199
the ability to tow a one hundred eight foot long

88
00:05:57.240 --> 00:06:01.399
trailer and navigate slopes up to twenty degree. One of

89
00:06:01.439 --> 00:06:04.360
the most innovative features of moon Racer is its dual

90
00:06:04.399 --> 00:06:08.680
mode operation. While astronauts can drive it manually, the vehicle

91
00:06:08.759 --> 00:06:13.000
is also capable of autonomous operation for robotic exploration. When

92
00:06:13.079 --> 00:06:16.279
crews aren't present. The rover can be controlled remotely from

93
00:06:16.399 --> 00:06:21.199
various locations including Houston, Australia, lunar habitats, and even the

94
00:06:21.240 --> 00:06:26.000
Gateway space station orbiting the Moon. The vehicle's communication capabilities

95
00:06:26.000 --> 00:06:29.920
are equally impressive, featuring antenna systems that can relay data

96
00:06:30.000 --> 00:06:34.160
via satellite or direct to Earth transmissions, ensuring constant connectivity

97
00:06:34.199 --> 00:06:38.720
during lunar operations. For safety and efficiency, Moon Racer is

98
00:06:38.759 --> 00:06:42.079
equipped with an advanced hazard avoidance system, allowing it to

99
00:06:42.160 --> 00:06:45.560
navigate challenging lunar terrain and clear obstacles up to a

100
00:06:45.560 --> 00:06:50.000
foot high. This development is part of NASA's Broader Artemis program,

101
00:06:50.360 --> 00:06:53.759
with Intuitive Machines being one of three companies selected to

102
00:06:53.800 --> 00:06:57.800
develop lunar terrain vehicles under a thirty million dollars contract.

103
00:06:58.560 --> 00:07:01.519
The stakes are high, as NASA plans to select one

104
00:07:01.560 --> 00:07:04.079
of these designs for deployment to the lunar South Pole

105
00:07:04.519 --> 00:07:07.199
before the Artemis five missions, scheduled for no earlier than

106
00:07:07.199 --> 00:07:10.800
twenty thirty. In a touching nod to space history, the

107
00:07:10.839 --> 00:07:14.199
static mockup of Moon Racer has already received the approval

108
00:07:14.240 --> 00:07:17.480
of Apollo veterans Charlie Duke and Harrison Schmidt, two of

109
00:07:17.519 --> 00:07:20.079
only six humans who have ever driven a rover on

110
00:07:20.120 --> 00:07:24.000
the lunar surface. Duke notably commented that this new vehicle

111
00:07:24.120 --> 00:07:26.879
was way more than we had, highlighting just how far

112
00:07:26.959 --> 00:07:31.480
lunar vehicle technology has progressed since the Apollo era. Let's

113
00:07:31.480 --> 00:07:34.160
head off to Mars now for an update. Exciting new

114
00:07:34.199 --> 00:07:36.759
findings from Mars are adding weight to a long debated

115
00:07:36.800 --> 00:07:41.040
theory about the red planet's watery past. China's Jorrong rover

116
00:07:41.480 --> 00:07:45.639
exploring the Utopia region in Mars's northern hemisphere, has uncovered

117
00:07:45.680 --> 00:07:48.399
compelling evidence that a vast ocean once covered up to

118
00:07:48.439 --> 00:07:52.279
a third of the planet's surface. The rover's investigation has

119
00:07:52.319 --> 00:07:56.319
revealed several tell tale features around its landing site, including

120
00:07:56.360 --> 00:08:02.279
pitted cones, polygonal troughs and etched flows. These geological formations

121
00:08:02.319 --> 00:08:06.519
are particularly significant because they typically form in areas where

122
00:08:06.560 --> 00:08:11.160
water or ice once existed. Perhaps most intriguingly, the research

123
00:08:11.199 --> 00:08:14.439
team has identified what appears to be an ancient shoreline

124
00:08:14.439 --> 00:08:17.639
near the study area. Using data from both the rover

125
00:08:17.800 --> 00:08:22.600
and satellite observations, scientists have pieced together a fascinating timeline.

126
00:08:22.680 --> 00:08:26.000
They estimate this Martian ocean form during a massive flooding

127
00:08:26.000 --> 00:08:30.600
event approximately three point seven billion years ago. The water

128
00:08:30.680 --> 00:08:34.600
body then experienced a freezing period which carved out distinctive

129
00:08:34.639 --> 00:08:38.879
coastal features before eventually disappearing around three point four billion

130
00:08:38.960 --> 00:08:43.600
years ago. This discovery could have profound implications for our

131
00:08:43.720 --> 00:08:48.840
understanding of Mars's potential to have once harbored life. On Earth,

132
00:08:49.159 --> 00:08:52.159
life is believed to have emerged either in deep ocean

133
00:08:52.240 --> 00:08:57.080
environments near hydrothermal vents or in shallow tidal pools where

134
00:08:57.080 --> 00:09:01.360
water meets air. The conformation of an ancient Martian ocean

135
00:09:01.759 --> 00:09:05.399
would suggest that similar conditions once existed on the Red planet.

136
00:09:06.679 --> 00:09:10.440
While the research team remains appropriately cautious about their findings,

137
00:09:11.000 --> 00:09:14.279
noting that definitive proof would likely require bringing Martian rock

138
00:09:14.320 --> 00:09:18.080
samples back to Earth for analysis. These new observations add

139
00:09:18.120 --> 00:09:21.759
another piece to the puzzle of Mars's mysterious past. They

140
00:09:21.759 --> 00:09:24.679
provide fresh evidence that the dry, dusty world we see

141
00:09:24.679 --> 00:09:28.120
today was once a much more dynamic and potentially habitable planet.

142
00:09:29.559 --> 00:09:33.759
Fascinating new research has emerged about Apophis, the asteroid nicknamed

143
00:09:33.799 --> 00:09:36.720
after the Egyptian god of chaos, and what might happen

144
00:09:36.840 --> 00:09:40.840
during its extremely close encounter with Earth in twenty twenty nine.

145
00:09:40.919 --> 00:09:43.480
While we've known about this approaching space rock for some time,

146
00:09:44.000 --> 00:09:47.399
scientists have now uncovered details about how Earth's gravity might

147
00:09:47.480 --> 00:09:52.320
dramatically reshape this celestial visitor. A Pofos, which measures about

148
00:09:52.320 --> 00:09:54.879
one thy one hundred feet in length and has a

149
00:09:54.919 --> 00:09:58.480
distinctive peanut shape, will pass within just twenty thousand miles

150
00:09:58.480 --> 00:10:02.399
of Earth, closer than some of our satellites. While this

151
00:10:02.480 --> 00:10:05.360
rules out any risk of impact, the close approach will

152
00:10:05.360 --> 00:10:09.360
subject the asteroid to intense gravitational forces that could trigger

153
00:10:09.440 --> 00:10:13.759
some remarkable changes. Computer simulations suggest that about an hour

154
00:10:13.879 --> 00:10:18.879
before its closest approach, a Pofas will begin experiencing significant tremors.

155
00:10:19.399 --> 00:10:22.279
Think of it as an asteroid quake, but in this case,

156
00:10:22.399 --> 00:10:26.320
Earth's gravitational pull is the trigger. These vibrations could be

157
00:10:26.360 --> 00:10:29.759
strong enough to actually launch boulders off the asteroid's surface.

158
00:10:30.600 --> 00:10:34.600
While some rocks might escape completely, most will likely fall back,

159
00:10:34.840 --> 00:10:38.919
creating new patterns on the asteroid's surface. But that's not all.

160
00:10:39.480 --> 00:10:42.799
The encounter is expected to affect how Apofus tumbles through space.

161
00:10:43.440 --> 00:10:47.559
Unlike a perfect spinning top, this asteroid currently rotates irregularly

162
00:10:48.080 --> 00:10:52.159
picture a poorly thrown football. Earth's gravitational influence will either

163
00:10:52.159 --> 00:10:54.879
speed up or slow down this tumbling motion, depending on

164
00:10:54.919 --> 00:10:58.879
the asteroid's orientation during the flyby. This change in rotation

165
00:10:59.000 --> 00:11:02.919
could destabilize surface rocks and potentially trigger landslides that would

166
00:11:02.960 --> 00:11:06.159
continue to reshape the asteroid for thousands of years afterward.

167
00:11:06.879 --> 00:11:09.879
NASA's Osiris APEX mission will be there to witness these

168
00:11:09.960 --> 00:11:13.960
changes firsthand. Having been repurposed from its successful Benu sample

169
00:11:14.000 --> 00:11:18.039
return mission, the spacecraft will spend eighteen months studying ap Office,

170
00:11:18.399 --> 00:11:21.279
giving us an unprecedented opportunity to watch how a close

171
00:11:21.320 --> 00:11:26.399
planetary encounter can transform an asteroid in real time. Finally,

172
00:11:26.720 --> 00:11:29.440
let's clear this up once and for all. In lighter

173
00:11:29.480 --> 00:11:32.600
News from Space Today, NASA has stepped forward to address

174
00:11:32.600 --> 00:11:36.720
some concerning tabloid reports about astronaut Sunny Williams's health aboard

175
00:11:36.759 --> 00:11:40.799
the International Space Station. Several media outlets, including The Daily

176
00:11:40.840 --> 00:11:44.320
Mail and The New York Post, had published speculative stories

177
00:11:44.360 --> 00:11:48.679
about Williams's condition, basing their concerns on a September photo

178
00:11:48.840 --> 00:11:52.720
where they claimed she appeared gaunt. NASA has firmly refuted

179
00:11:52.720 --> 00:11:57.879
these claims, stating unequivocally that Williams, who currently commands Expedition

180
00:11:57.919 --> 00:12:02.519
seventy two, is in perfect health. The Space agency emphasized

181
00:12:02.559 --> 00:12:05.480
that they are not tracking any health concerns with Williams

182
00:12:05.879 --> 00:12:09.360
or any other NASA astronauts currently aboard the station. This

183
00:12:09.440 --> 00:12:13.600
situation highlights the robust medical monitoring system in place for

184
00:12:13.679 --> 00:12:18.039
astronauts on the ISS. Each crew member undergoes regular medical

185
00:12:18.039 --> 00:12:22.120
evaluations and has dedicated flight surgeons watching over their health

186
00:12:22.279 --> 00:12:26.080
throughout their mission. Williams and her fellow astronaut Butch Wilmore

187
00:12:26.320 --> 00:12:29.519
have been aboard the station since June, arriving on Boeing's

188
00:12:29.559 --> 00:12:33.679
Starliner spacecraft. While their stay has been extended longer than

189
00:12:33.720 --> 00:12:37.759
initially planned due to technical issues with Starliner's thruster system,

190
00:12:38.600 --> 00:12:42.080
NASA has confirmed they have plenty of supplies, including food

191
00:12:42.399 --> 00:12:46.279
to support the extended mission. Williams and Wilmore are now

192
00:12:46.320 --> 00:12:49.320
scheduled to return to Earth in February twenty twenty five,

193
00:12:49.879 --> 00:12:54.000
traveling back with the SpaceX Crew nine mission. This episode

194
00:12:54.039 --> 00:12:57.559
serves as an important reminder about the necessity of relying

195
00:12:57.600 --> 00:13:01.600
on official sources for space related news rather than speculative

196
00:13:01.639 --> 00:13:05.159
reporting that can cause unnecessary concern about our astronauts well being.

197
00:13:07.159 --> 00:13:10.720
And that wraps up today's episode of Astronomy Daily. From

198
00:13:10.720 --> 00:13:14.279
