00:00:00.200 --> 00:00:03.040
Welcome to Astronomy Daily, your source for the latest space

2
00:00:03.040 --> 00:00:06.160
and astronomy news. I'm your host, Anna, and today we've

3
00:00:06.200 --> 00:00:08.359
got an exciting lineup of stories to share with you.

4
00:00:08.800 --> 00:00:12.320
We'll be covering NASA's legendary Voyager one spacecraft returning to

5
00:00:12.400 --> 00:00:16.440
full operations after a communication issue, taking a peek at

6
00:00:16.440 --> 00:00:20.839
how astronauts celebrated Thanksgiving aboard the International Space Station, and

7
00:00:20.920 --> 00:00:25.760
getting updates on SpaceX's Starship program. We'll also explore fascinating

8
00:00:25.800 --> 00:00:29.719
new findings from asteroid Ryugu samples, and look at China's

9
00:00:29.760 --> 00:00:33.880
latest achievements in space, including new mapping satellites and cargo missions.

10
00:00:34.399 --> 00:00:36.640
Stay with us for all these stories and more, so

11
00:00:36.719 --> 00:00:41.079
let's get started. In an impressive display of engineering prowess,

12
00:00:41.520 --> 00:00:44.920
NASA has successfully brought Voyager one back to full operations

13
00:00:44.960 --> 00:00:49.880
following a concerning communication disruption last month. The veteran spacecraft,

14
00:00:50.320 --> 00:00:53.439
now an incredible fifteen point four billion miles from Earth,

15
00:00:53.960 --> 00:00:57.960
had unexpectedly switched from its primary X band radio transmitter

16
00:00:58.439 --> 00:01:02.399
to a weaker S band transmitter, temporarily halting the flow

17
00:01:02.479 --> 00:01:07.400
of valuable scientific and engineering data. The situation was particularly

18
00:01:07.480 --> 00:01:11.799
challenging given the vast distance involved it takes nearly twenty

19
00:01:11.840 --> 00:01:14.480
three hours for signals to make a round trip between

20
00:01:14.519 --> 00:01:19.840
Earth and Voyager one, but earlier this month, mission engineers

21
00:01:19.879 --> 00:01:24.040
managed to reactivate the x band transmitter, restoring data collection

22
00:01:24.159 --> 00:01:28.079
from all four of Voyager's operational science instruments. The issue

23
00:01:28.079 --> 00:01:31.879
stemmed from the spacecraft's fault protection system, which had deactivated

24
00:01:31.920 --> 00:01:35.519
the XPAN transmitter when a heater was activated. This protective

25
00:01:35.560 --> 00:01:39.920
measure is crucial for preserving power for critical operations, especially

26
00:01:39.959 --> 00:01:44.680
given Voyager one's extremely limited power supply. The spacecraft relies

27
00:01:44.680 --> 00:01:48.400
on electricity generated by the heat from decaying plutonium, which

28
00:01:48.439 --> 00:01:51.840
decreases by about four watts every year. What makes this

29
00:01:51.920 --> 00:01:55.799
achievement even more remarkable is that both Voyager spacecraft are

30
00:01:55.840 --> 00:02:00.159
operating with razor thin power margins. Over the years, the

31
00:02:00.200 --> 00:02:03.560
mission team has had to make difficult decisions, shutting down

32
00:02:03.640 --> 00:02:06.879
all non essential systems to keep these historic probes functioning.

33
00:02:07.760 --> 00:02:12.159
Despite operating in temperatures far colder than their original design specifications,

34
00:02:12.599 --> 00:02:15.960
the remaining science instruments continue to send back valuable data

35
00:02:16.000 --> 00:02:20.639
about interstellar space. After forty seven years of operation, Voyager

36
00:02:20.639 --> 00:02:23.800
one and its twin, Voyager two, remain the only human

37
00:02:23.840 --> 00:02:28.159
made objects operating in interstellar space. While their advanced age

38
00:02:28.159 --> 00:02:32.479
presents ongoing challenges for NASA's mission team, this latest recovery

39
00:02:32.520 --> 00:02:36.759
demonstrates the incredible durability of these pioneering spacecraft and the

40
00:02:36.800 --> 00:02:41.120
dedication of the engineers who keep them running. Now here's

41
00:02:41.120 --> 00:02:44.000
a story for our many listeners who like to celebrate Thanksgiving.

42
00:02:44.759 --> 00:02:47.319
The holiday season took on a whole new perspective this year,

43
00:02:47.680 --> 00:02:51.639
as four NASA astronauts aboard the International Space Station shared

44
00:02:51.680 --> 00:02:55.680
their unique Thanksgiving celebration with us here on Earth. Commander

45
00:02:55.719 --> 00:02:59.319
Sunny Williams, along with crewmates Don Pettitt, Nick Haig, and

46
00:02:59.360 --> 00:03:03.520
Butch Wilmore, beamed down a special message from their orbital home,

47
00:03:04.000 --> 00:03:06.800
giving us a glimpse into how they're marking this traditionally

48
00:03:06.840 --> 00:03:11.039
earthbound holiday. While most of us gathered around dining room tables,

49
00:03:11.479 --> 00:03:15.639
these astronauts celebrated with their own special feast, though perhaps

50
00:03:15.680 --> 00:03:19.280
not quite what you'd expect. Their Thanksgiving spread included some

51
00:03:19.400 --> 00:03:24.319
familiar holiday favorites like smoked turkey and butternut squash, along

52
00:03:24.319 --> 00:03:27.800
with some more unusual additions like Brussels sprouts and believe

53
00:03:27.840 --> 00:03:32.280
it or not, sardines, all carefully prepared for consumption in microgravity.

54
00:03:32.719 --> 00:03:34.560
The crew took a moment to reflect on what they're

55
00:03:34.599 --> 00:03:39.199
thankful for, with Butch Wilmore noting some uniquely astronauts specific blessings,

56
00:03:39.280 --> 00:03:41.800
including the ability to lay on the ceiling thanks to

57
00:03:41.919 --> 00:03:46.080
zero gravity. But they also shared more universal sentiments of gratitude,

58
00:03:46.360 --> 00:03:50.000
appreciation for family, friends, and the support of those back

59
00:03:50.039 --> 00:03:53.120
on Earth who keep them connected to home. Don Pettit

60
00:03:53.240 --> 00:03:55.840
touched on something many of us can relate to the

61
00:03:55.960 --> 00:03:58.800
challenge of being away from loved ones during the holidays,

62
00:03:59.199 --> 00:04:02.360
but he pointed out that modern technology allows them to

63
00:04:02.400 --> 00:04:06.199
stay connected virtually with family and friends, even from two

64
00:04:06.319 --> 00:04:09.520
hundred and fifty miles above Earth. It's a reminder that

65
00:04:09.560 --> 00:04:13.199
whether we're separated by continents or orbital planes, the spirit

66
00:04:13.240 --> 00:04:16.360
of togetherness that defines Thanksgiving finds a way to bridge

67
00:04:16.360 --> 00:04:21.839
the gap. Let's move on to some SpaceX news. SpaceX

68
00:04:21.879 --> 00:04:25.560
continues to make significant strides with its Starship program following

69
00:04:25.600 --> 00:04:28.920
the successful completion of Flight six. The aftermath of this

70
00:04:29.079 --> 00:04:33.000
latest test has kept teams busy at Starbase, with comprehensive

71
00:04:33.040 --> 00:04:36.600
inspection and repair work underway across various systems and structures

72
00:04:37.600 --> 00:04:41.120
in the immediate hours after the launch, engineers began examining

73
00:04:41.120 --> 00:04:44.600
the launch tower's chopsticks, the mechanical arms designed to catch

74
00:04:44.639 --> 00:04:48.720
returning vehicles. While these systems experience less stress than during

75
00:04:48.759 --> 00:04:51.560
flight five due to the absence of a booster landing attempt,

76
00:04:51.800 --> 00:04:55.439
the sheer power of all thirty three Raptor engines necessitated

77
00:04:55.480 --> 00:04:59.560
thorough checkups. The launch mount has received particular attention, with

78
00:04:59.560 --> 00:05:02.800
scaffold holding quickly installed around its upper section and the

79
00:05:02.839 --> 00:05:06.560
implementation of the dance floor, a movable platform that allows

80
00:05:06.600 --> 00:05:10.720
detailed inspection of the mount's lower sections. These rapid response

81
00:05:10.759 --> 00:05:15.560
protocols have become increasingly efficient with each launch, demonstrating SpaceX's

82
00:05:15.560 --> 00:05:20.319
growing expertise in postflight operations. Several systems showed signs of

83
00:05:20.319 --> 00:05:23.879
wear from flight six, including the booster quick disconnect system,

84
00:05:24.160 --> 00:05:27.720
which required repairs after being scorched during launch. The ship

85
00:05:27.800 --> 00:05:31.639
quick disconnect arm also sustained damage, with burnt umbilicals and

86
00:05:31.759 --> 00:05:36.040
notable charring on protective doors. Perhaps most surprisingly, the tower's

87
00:05:36.079 --> 00:05:40.360
weather and communications antenna experienced bending from launch forces, a

88
00:05:40.439 --> 00:05:44.879
first for the program. Looking ahead to flight seven, preparations

89
00:05:44.920 --> 00:05:48.519
are already well underway. Booster fourteen has completed its initial

90
00:05:48.560 --> 00:05:52.199
cryogenic testing and is being fitted with grid fins. Ship

91
00:05:52.279 --> 00:05:55.399
thirty three, designated as the first Block two ship to fly,

92
00:05:55.800 --> 00:05:58.839
has received its full complement of six Raptor two engines

93
00:05:58.839 --> 00:06:02.439
and is preparing for static five testing. The launch profile

94
00:06:02.480 --> 00:06:05.600
for Flight seven appears similar to its predecessors, with the

95
00:06:05.639 --> 00:06:08.439
ship targeted to land in the Indian Ocean near Australia.

96
00:06:09.000 --> 00:06:11.519
If current planning holds, we could see this next launch

97
00:06:11.519 --> 00:06:15.959
as early as January eleventh. Looking further ahead, SpaceX has

98
00:06:16.000 --> 00:06:19.959
ambitious plans for twenty twenty five, with environmental assessments underway

99
00:06:20.160 --> 00:06:23.680
to support up to twenty five launches from Starbase, including

100
00:06:23.720 --> 00:06:28.040
three night launches, though these currently won't include booster landing attempts.

101
00:06:29.439 --> 00:06:32.360
Next up today. In a fascinating development from the world

102
00:06:32.360 --> 00:06:36.600
of asteroid sample analysis, scientists have discovered that specimens from

103
00:06:36.639 --> 00:06:41.639
asteroid Reyugu became home to Earth based microorganisms after their

104
00:06:41.680 --> 00:06:45.839
return to our planet. This finding emerged during research led

105
00:06:45.879 --> 00:06:50.160
by Matthew Gene at Imperial College London, providing valuable insights

106
00:06:50.199 --> 00:06:55.240
into how terrestrial life forms interact with extraterrestrial materials. The

107
00:06:55.319 --> 00:06:59.759
sample in question collected by Jacksa's Hyabusa two spacecraft and

108
00:06:59.759 --> 00:07:03.560
reat turned to Earth in December twenty twenty, showed remarkable

109
00:07:03.560 --> 00:07:07.800
evidence of microbial colonization. Within just one week of exposure

110
00:07:07.839 --> 00:07:12.480
to Earth's atmosphere, scientists observed eleven microbes on the sample's surface.

111
00:07:13.519 --> 00:07:17.079
Even More impressively, this population exploded to one hundred and

112
00:07:17.160 --> 00:07:21.759
forty seven microorganisms just a week later. While initially intriguing,

113
00:07:22.120 --> 00:07:26.199
the team conclusively determined these weren't alien life forms. Their

114
00:07:26.240 --> 00:07:30.120
appearance only after the sample's exposure to Earth's atmosphere, combined

115
00:07:30.120 --> 00:07:34.319
with their rapid population growth, clearly identified them as terrestrial

116
00:07:34.360 --> 00:07:38.279
in origin. The microorganisms were likely bacteria, similar to the

117
00:07:38.279 --> 00:07:42.439
common basilla species found in soil and rocks. This discovery

118
00:07:42.480 --> 00:07:47.639
has significant implications for future space exploration, particularly regarding planetary

119
00:07:47.639 --> 00:07:52.560
protection protocols. It demonstrates just how readily Earth based microorganisms

120
00:07:52.560 --> 00:07:57.680
can colonize and survive on extraterrestrial materials, raising important considerations

121
00:07:57.720 --> 00:08:00.839
for both sample return missions and planet time cary exploration.

122
00:08:01.759 --> 00:08:04.439
The findings serve as a crucial reminder of the challenges

123
00:08:04.439 --> 00:08:08.519
we face in maintaining pristine conditions when studying materials from space.

124
00:08:09.279 --> 00:08:12.920
They also highlight the importance of careful contamination controls in

125
00:08:12.959 --> 00:08:16.519
future missions, especially as we continue our search for evidence

126
00:08:16.560 --> 00:08:20.639
of life beyond Earth. The research underscores an impressive, yet

127
00:08:20.680 --> 00:08:26.639
concerning truth. Earth's microorganisms are remarkably successful colonizers, capable of

128
00:08:26.720 --> 00:08:30.040
establishing themselves even on materials from millions of miles away.

129
00:08:30.920 --> 00:08:34.399
This adaptability could have profound implications for our understanding of

130
00:08:34.399 --> 00:08:37.879
how life might spread throughout the Solar System, whether naturally

131
00:08:38.080 --> 00:08:43.159
or through human exploration. China's space program continues to mark

132
00:08:43.200 --> 00:08:48.360
significant milestones with several notable developments. This month. The Tianzo

133
00:08:48.559 --> 00:08:52.360
seven cargo spacecraft, which had been serving China's Tiangong space

134
00:08:52.399 --> 00:08:56.279
station since January, completed its mission with a controlled re

135
00:08:56.440 --> 00:09:00.559
entry into Earth's atmosphere. After delivering crucial supple to the

136
00:09:00.559 --> 00:09:04.480
station and being loaded with waste materials, the spacecraft made

137
00:09:04.519 --> 00:09:08.679
its final descent on November seventeenth, providing US with spectacular

138
00:09:08.720 --> 00:09:12.799
footage of its fiery return through Earth's atmosphere. But before

139
00:09:12.840 --> 00:09:18.120
its dramatic finale, Tianzo seven had one last task to complete.

140
00:09:18.200 --> 00:09:21.519
The spacecraft deployed a small satellite called Bye zero eight,

141
00:09:22.039 --> 00:09:26.879
equipped with Earth observation capabilities and optical communication systems, adding

142
00:09:26.919 --> 00:09:31.720
another piece to China's growing space infrastructure. In a separate development,

143
00:09:31.840 --> 00:09:35.919
China has bolstered its satellite imaging capabilities with the successful

144
00:09:36.000 --> 00:09:40.080
launch of two new mapping satellites, The Seaway Gouging two,

145
00:09:40.240 --> 00:09:43.320
zero three and zero four satellites, lifted off aboard a

146
00:09:43.360 --> 00:09:47.279
long March two sea rocket from the Juquan Satellite Launch Center.

147
00:09:47.919 --> 00:09:52.000
These advanced satellites represent a significant upgrade to China's existing network,

148
00:09:52.440 --> 00:09:56.639
featuring high precision radar systems capable of producing detailed images

149
00:09:57.000 --> 00:10:00.519
regardless of weather conditions or time of day. What makes

150
00:10:00.559 --> 00:10:05.399
these satellites particularly noteworthy is their enhanced payload efficiency, which

151
00:10:05.399 --> 00:10:09.480
has improved by twenty five percent over previous versions. They're

152
00:10:09.480 --> 00:10:13.200
designed to support a wide range of applications, from natural

153
00:10:13.240 --> 00:10:18.360
resource management to urban safety and emergency response. The satellite's

154
00:10:18.399 --> 00:10:22.480
all weather imaging capabilities make them especially valuable for disaster management,

155
00:10:22.960 --> 00:10:26.960
allowing rapid assessment of natural disasters even under challenging conditions.

156
00:10:27.840 --> 00:10:32.440
These developments highlight China's growing sophistication in space operations, from

157
00:10:32.559 --> 00:10:36.639
maintaining a permanent space station to expanding its satellite infrastructure

158
00:10:36.679 --> 00:10:40.840
for both commercial and scientific purposes. It's another reminder of

159
00:10:40.840 --> 00:10:44.200
how space technology continues to evolve and advance across multiple

160
00:10:44.279 --> 00:10:48.600
nations and programs. While that brings us to the end
