00:00:00.200 --> 00:00:01.439
Welcome to Astronomy Daily.

2
00:00:01.720 --> 00:00:04.200
I'm excited to bring you another packed episode of space

3
00:00:04.240 --> 00:00:07.160
and astronomy news. We've got some incredible stories lined up

4
00:00:07.200 --> 00:00:11.080
for you today that showcase humanity's ongoing exploration of the cosmos.

5
00:00:11.599 --> 00:00:14.439
We'll start with an update on NASA's Parker Solar Probe's

6
00:00:14.480 --> 00:00:18.199
remarkable Christmas Eve achievement, as it made its closest approach

7
00:00:18.280 --> 00:00:21.359
ever to our Sun while becoming the fastest human made

8
00:00:21.399 --> 00:00:25.399
object in history. Then we'll explore China's ambitious plans for

9
00:00:25.480 --> 00:00:28.719
new rocket launches in twenty twenty five, which could reshape

10
00:00:28.719 --> 00:00:33.000
their space capabilities. We'll also dive into some fascinating research

11
00:00:33.039 --> 00:00:36.880
about icy worlds like Europa, examine a recent software glitch

12
00:00:36.920 --> 00:00:41.000
that affected satellite communications, and look ahead to some spectacular

13
00:00:41.039 --> 00:00:42.600
celestial events coming our way.

14
00:00:43.399 --> 00:00:45.159
The universe keeps surprising us.

15
00:00:45.079 --> 00:00:47.560
With new discoveries, and I can't wait to share them

16
00:00:47.560 --> 00:00:47.960
all with you.

17
00:00:48.679 --> 00:00:50.000
Let's get into today's news.

18
00:00:51.520 --> 00:00:55.960
On Christmas Eve, NASA's Parker Solar Probe achieved an extraordinary feat,

19
00:00:56.439 --> 00:00:59.280
skimming closer to the Sun than any human made object

20
00:00:59.320 --> 00:01:03.200
has ever entered at precisely six fifty three am Eastern

21
00:01:03.240 --> 00:01:06.519
Time on December twenty fourth, the spacecraft passed within just

22
00:01:06.640 --> 00:01:10.359
six point one million kilometers of the Sun's surface, shattering

23
00:01:10.400 --> 00:01:13.239
its own previous record of seven point two six million

24
00:01:13.319 --> 00:01:16.680
kilometers set earlier in twenty twenty three. But that wasn't

25
00:01:16.719 --> 00:01:20.239
the only record broken that day. During its closest approach,

26
00:01:20.680 --> 00:01:24.040
the probe became the fastest object ever created by humans,

27
00:01:24.359 --> 00:01:27.280
reaching a mind boggling speed of six hundred ninety two

28
00:01:27.359 --> 00:01:31.959
thousand kilometers per hour. To put that incredible velocity into perspective,

29
00:01:32.359 --> 00:01:35.400
At that speed, you could travel from Philadelphia to Washington,

30
00:01:35.480 --> 00:01:39.400
d C. In about one second. This remarkable achievement marks

31
00:01:39.439 --> 00:01:42.599
the culmination of six years in space for the Parker

32
00:01:42.640 --> 00:01:46.519
Solar Probe. Since its launch in twenty eighteen, the spacecraft

33
00:01:46.519 --> 00:01:49.040
has been on a complex journey to study the Sun's

34
00:01:49.040 --> 00:01:53.040
outer atmosphere or corona from the inside. Due to the

35
00:01:53.079 --> 00:01:57.280
Sun's powerful gravitational pull, the probe couldn't simply fly straight

36
00:01:57.319 --> 00:02:00.480
to its destination. Instead, it has been perform warming an

37
00:02:00.480 --> 00:02:04.680
intricate orbital dance, using Venus's gravity to gradually adjust its

38
00:02:04.680 --> 00:02:09.199
path closer to the Sun. Through twenty one increasingly narrow flybys,

39
00:02:10.039 --> 00:02:13.840
the mission reached a crucial milestone on November six, when

40
00:02:13.840 --> 00:02:17.280
the final Venus flyby positioned the probe into its optimal orbit.

41
00:02:18.080 --> 00:02:21.599
This carefully calculated position allows the spacecraft to study the

42
00:02:21.639 --> 00:02:25.039
Sun's processes up close while remaining just far enough away

43
00:02:25.039 --> 00:02:29.000
to avoid destruction. During its closest approach, the probe was

44
00:02:29.039 --> 00:02:31.280
completely out of contact with Earth for about a week.

45
00:02:31.759 --> 00:02:35.439
The tension finally broke just before midnight on December twenty seventh,

46
00:02:35.800 --> 00:02:39.000
when scientists received a beacon signal confirming the spacecraft had

47
00:02:39.039 --> 00:02:43.240
survived its daring encounter. Three days later, on New Year's Day,

48
00:02:43.639 --> 00:02:47.400
more detailed data arrived, showing the probe was healthy and

49
00:02:47.479 --> 00:02:51.479
had successfully collected scientific measurements during its record breaking flyby.

50
00:02:52.120 --> 00:02:55.240
Mission controllers must have breathed a huge sigh of relief.

51
00:02:55.759 --> 00:02:58.240
The probe will maintain this new orbit for at least

52
00:02:58.319 --> 00:03:01.560
nine months, with two more equally close passes planned for

53
00:03:01.680 --> 00:03:05.520
March and June before its primary mission concludes in September

54
00:03:05.560 --> 00:03:09.919
twenty twenty five. These repeated close encounters promised to reveal

55
00:03:10.080 --> 00:03:13.879
unprecedented details about our star's behavior and help us better

56
00:03:13.960 --> 00:03:18.680
understand the forces that shape our solar system. Next up today,

57
00:03:19.120 --> 00:03:22.560
Utelsat recently reported a significant disruption to their one Web

58
00:03:22.599 --> 00:03:26.120
satellite network that left users without service for two days.

59
00:03:26.520 --> 00:03:29.919
The outage, which began on December thirty first, was traced

60
00:03:29.960 --> 00:03:32.719
back to a rather familiar culprit in the computing world,

61
00:03:33.360 --> 00:03:36.639
a leap year software bug in their ground segment systems.

62
00:03:37.360 --> 00:03:40.000
The timing couldn't have been more ironic, as the system

63
00:03:40.039 --> 00:03:42.560
failed to properly account for twenty twenty four being a

64
00:03:42.639 --> 00:03:47.120
leap year. Services were only partially restored after thirty six hours,

65
00:03:47.560 --> 00:03:52.360
with full functionality returning shortly thereafter. This incident highlights just

66
00:03:52.400 --> 00:03:56.280
how complex modern satellite networks are and how even seemingly

67
00:03:56.319 --> 00:04:00.479
simple oversights can have far reaching consequences. And what makes

68
00:04:00.479 --> 00:04:03.960
this particularly noteworthy is that one Web had just recently

69
00:04:04.000 --> 00:04:07.520
achieved the capability for worldwide coverage in twenty twenty three.

70
00:04:08.560 --> 00:04:11.479
The company has been steadily working to expand its services

71
00:04:11.520 --> 00:04:15.159
across the Americas, Europe, and Asia, with plans to launch

72
00:04:15.199 --> 00:04:20.560
full services for government and enterprise customers, including aviation, this spring.

73
00:04:21.560 --> 00:04:25.040
The good news is that utlsat's multi orbit capabilities should

74
00:04:25.079 --> 00:04:29.240
provide better network resilience in the future. The company operates

75
00:04:29.279 --> 00:04:32.560
both the one Web constellation in low Earth orbit and

76
00:04:32.639 --> 00:04:36.759
a fleet of thirty five geostationary satellites. This dual system

77
00:04:36.759 --> 00:04:39.439
approach is part of their strategy to compete with industry

78
00:04:39.480 --> 00:04:42.879
leader Starlink, allowing them to supplement one Web services with

79
00:04:42.959 --> 00:04:48.519
geostationary capacity in high demand areas. Looking ahead. UTLSAT isn't

80
00:04:48.560 --> 00:04:51.879
letting this set back slow their momentum. They've already ordered

81
00:04:51.879 --> 00:04:54.519
one hundred new one Web satellites from Airbus Defense in

82
00:04:54.600 --> 00:04:58.480
Space to ensure the constellation remains robust as the current

83
00:04:58.519 --> 00:05:01.519
satellites reach the end of their DESI lives in twenty

84
00:05:01.600 --> 00:05:05.839
twenty seven and twenty twenty eight. Next we head on

85
00:05:05.920 --> 00:05:08.560
over to a country that's fast becoming a major space

86
00:05:08.600 --> 00:05:11.680
force to be reckoned with. China is gearing up for

87
00:05:11.759 --> 00:05:15.040
an exciting year in space, with twenty twenty five set

88
00:05:15.079 --> 00:05:17.839
to see the debut of several new rockets from both

89
00:05:17.879 --> 00:05:22.360
state owned enterprises and commercial companies. These new launchers represent

90
00:05:22.439 --> 00:05:27.079
a significant leap forward in China's space capabilities, particularly in

91
00:05:27.120 --> 00:05:31.079
the realm of reusable technology. Leading the charge is the

92
00:05:31.160 --> 00:05:34.680
Long March eight A, an upgraded version of the existing

93
00:05:34.759 --> 00:05:38.079
Long March eighth rocket. This new variant features a more

94
00:05:38.120 --> 00:05:41.879
powerful second stage that boosts its payload capacity to seven

95
00:05:41.920 --> 00:05:46.480
thousand kilograms to Sun synchronous orbit. What's particularly interesting is

96
00:05:46.480 --> 00:05:50.519
that they're incorporating a larger five dot two dash meter

97
00:05:50.680 --> 00:05:55.199
dash diameter payload firing, giving them more flexibility for future missions.

98
00:05:55.759 --> 00:05:59.199
Another notable development is the Long March twelve A, which

99
00:05:59.240 --> 00:06:02.959
is taking a paide from SpaceX's playbook by implementing vertical

100
00:06:03.000 --> 00:06:07.480
takeoff and vertical landing capabilities. This marks China's first serious

101
00:06:07.560 --> 00:06:11.639
venture into reusable rocket technology at the state level. The

102
00:06:11.639 --> 00:06:15.399
commercial sector is equally ambitious. Land Space is preparing their

103
00:06:15.519 --> 00:06:18.759
jw K three rocket, a massive stainless steel launcher that

104
00:06:18.839 --> 00:06:23.600
will stand seventy six meters tall inexpendable configuration, it will

105
00:06:23.600 --> 00:06:26.920
be capable of lifting twenty one thousand kilograms to low

106
00:06:26.959 --> 00:06:30.920
Earth orbit or eighteen thouy three hundred kilograms when recovering

107
00:06:30.959 --> 00:06:35.920
the first stage downrange. This impressive capability puts it in

108
00:06:35.959 --> 00:06:39.879
direct competition with some of the most powerful rockets currently operating.

109
00:06:40.480 --> 00:06:43.399
We're also seeing several other commercial players entering the field.

110
00:06:43.839 --> 00:06:47.360
Galactic Energy is developing both the Palace one, designed for

111
00:06:47.399 --> 00:06:52.480
eventual reusability, and the upgraded Series two solid rocket cast

112
00:06:52.560 --> 00:06:56.199
space a spinoff from the Chinese Academy of Sciences is

113
00:06:56.240 --> 00:06:59.399
working on their Kinnetica two rocket, which aims to serve

114
00:06:59.519 --> 00:07:03.399
China's growth growing commercial space sector. These new rockets aren't

115
00:07:03.439 --> 00:07:07.319
just about showing technological prowess, they serve a practical purpose.

116
00:07:08.000 --> 00:07:11.120
They'll be competing for contracts to launch satellites for China's

117
00:07:11.160 --> 00:07:16.800
ambitious mega constellation projects, space station cargo missions, and commercial payloads.

118
00:07:17.319 --> 00:07:20.480
This expansion in launch capabilities is essential for China's growing

119
00:07:20.519 --> 00:07:25.480
space program and could potentially attract international customers, though geopolitical

120
00:07:25.560 --> 00:07:29.319
challenges remain a consideration. The influx of new launch vehicles,

121
00:07:29.360 --> 00:07:34.000
particularly those incorporating reusability, signals China's commitment to developing a

122
00:07:34.079 --> 00:07:37.639
robust and competitive space industry. While some of these companies

123
00:07:37.639 --> 00:07:41.000
will be competing for limited domestic contracts, the end result

124
00:07:41.079 --> 00:07:43.920
will likely be a more capable and cost effective space

125
00:07:43.959 --> 00:07:48.480
launch sector for China. Exciting new research has emerged that

126
00:07:48.519 --> 00:07:52.279
could revolutionize our understanding of icy ocean worlds like Jupiter's

127
00:07:52.319 --> 00:07:56.759
moon Europa. Scientists have introduced a novel concept called the Senatectic,

128
00:07:57.240 --> 00:07:59.759
which helps us understand how liquid water can remain stable

129
00:07:59.800 --> 00:08:03.879
and or extreme conditions on these distant worlds. The research

130
00:08:03.920 --> 00:08:07.680
published in Nature Communications, comes from a fascinating collaboration between

131
00:08:07.680 --> 00:08:11.800
doctor Matt Powell Palm from Texas AA and DM University,

132
00:08:12.279 --> 00:08:16.879
and planetary scientist doctor Baptiste Journau from the University of Washington.

133
00:08:17.759 --> 00:08:21.040
Their work couldn't be more timely as NASA's Europa Clipper

134
00:08:21.079 --> 00:08:24.720
mission prepares for its journey to Jupiter's mysterious ice covered moon.

135
00:08:25.319 --> 00:08:29.360
But what exactly is the Senatectic. It's essentially the absolute

136
00:08:29.360 --> 00:08:33.039
lowest temperature at which liquid water can remain stable under

137
00:08:33.080 --> 00:08:37.399
different pressures and concentrations. Think of it as a thermodynamic

138
00:08:37.440 --> 00:08:40.840
boundary that helps us determine where liquid water might exist

139
00:08:40.919 --> 00:08:45.360
on these icy moons, even under seemingly impossible conditions. What

140
00:08:45.480 --> 00:08:48.480
makes this research particularly intriguing is how it bridges two

141
00:08:48.679 --> 00:08:54.120
very different fields. Powell Palm's expertise in cryobiology, originally focused

142
00:08:54.159 --> 00:08:58.399
on medical applications like organ preservation, combines with Journau's knowledge

143
00:08:58.440 --> 00:09:01.679
of planetary science to create a powerful new framework for

144
00:09:01.799 --> 00:09:07.159
understanding these alien environments. With NASA's Europa Clipper mission representing

145
00:09:07.240 --> 00:09:11.639
the largest planetary exploration mission ever launched, this research couldn't

146
00:09:11.679 --> 00:09:14.200
come at a better time. The mission will help us

147
00:09:14.279 --> 00:09:17.080
understand how deep Europa's ocean is and what it's made of.

148
00:09:17.960 --> 00:09:21.639
When combined with these new laboratory findings about liquid stability,

149
00:09:21.960 --> 00:09:25.080
we'll be able to better assess just how habitable these cold,

150
00:09:25.120 --> 00:09:29.720
deep oceans might be. The implications are profound. This research

151
00:09:29.759 --> 00:09:32.679
doesn't just help us understand Europa. It could apply to

152
00:09:32.799 --> 00:09:36.399
numerous other icy worlds throughout our Solar system. As we

153
00:09:36.480 --> 00:09:39.559
continue to search for potential habitats for life beyond Earth,

154
00:09:39.960 --> 00:09:43.919
understanding these fundamental properties of water under extreme conditions becomes

155
00:09:43.960 --> 00:09:48.919
increasingly crucial. This work represents another step forward in our

156
00:09:49.000 --> 00:09:52.720
quest to understand these fascinating worlds and their potential to

157
00:09:52.799 --> 00:09:57.919
harbor life, demonstrating how breakthroughs in seemingly unrelated fields can

158
00:09:57.960 --> 00:10:01.919
come together to unlock the mysteries of our cosmic neighborhood.

159
00:10:03.159 --> 00:10:07.000
Now something to look forward to. Space enthusiasts and skywatchers

160
00:10:07.039 --> 00:10:09.399
are in for a treat in twenty twenty five, with

161
00:10:09.519 --> 00:10:13.279
four spectacular eclipses on the calendar. While we won't see

162
00:10:13.279 --> 00:10:16.320
any total solar eclipses this year, we'll be treated to

163
00:10:16.399 --> 00:10:20.200
two total lunar eclipses, something we haven't experienced since twenty

164
00:10:20.279 --> 00:10:24.200
twenty two. The first major event comes on March fourteenth,

165
00:10:24.240 --> 00:10:27.559
with a total lunar eclipse that's perfectly timed for viewers

166
00:10:27.600 --> 00:10:31.000
across North and South America. If you're in the contiguous

167
00:10:31.120 --> 00:10:34.320
United States, Mexico, or Canada, you'll be able to witness

168
00:10:34.360 --> 00:10:37.559
the entire show, from the first shadow crossing the Moon's

169
00:10:37.559 --> 00:10:40.840
face to the last. During totality, which lasts for sixty

170
00:10:40.919 --> 00:10:44.080
six minutes, keep an eye on the Moon's northern edge.

171
00:10:44.360 --> 00:10:46.480
It should appear slightly brighter than the rest of the

172
00:10:46.480 --> 00:10:50.120
shadow disc. Two weeks later, on March twenty ninth, we'll

173
00:10:50.159 --> 00:10:53.679
see the year's first partial solar eclipse. While Europe and

174
00:10:53.720 --> 00:10:56.559
Northwest Africa will get a good view, the best location

175
00:10:56.720 --> 00:11:00.000
will actually be in Quebec near Hudson Bay, where Absuer

176
00:11:00.360 --> 00:11:02.759
can witness up to ninety three percent of the Sun's

177
00:11:02.799 --> 00:11:07.159
disc covered at sunrise. September brings our second pair of eclipses,

178
00:11:07.559 --> 00:11:11.039
starting with another total lunar eclipse on the seventh. This

179
00:11:11.080 --> 00:11:14.480
one favors the eastern hemisphere, making it a perfect evening

180
00:11:14.559 --> 00:11:18.039
show for Europe and Africa, while Asia and Australia will

181
00:11:18.039 --> 00:11:20.879
catch it in the early morning hours of September eighth.

182
00:11:21.320 --> 00:11:24.919
The eclipse's totality will last and impressive eighty two minutes.

183
00:11:25.480 --> 00:11:28.879
The year's final eclipse occurs on September twenty first, with

184
00:11:28.960 --> 00:11:32.000
a partial solar eclipse that will be primarily visible from

185
00:11:32.000 --> 00:11:33.919
the South Pacific and Southern Oceans.

186
00:11:34.639 --> 00:11:35.679
New Zealand will get the.

187
00:11:35.600 --> 00:11:38.799
Best populated area of view, with up to seventy three

188
00:11:38.840 --> 00:11:42.519
percent of the Sun's disc covered from the country's southern regions.

189
00:11:43.559 --> 00:11:46.480
While this might seem like a relatively quiet year for eclipses,

190
00:11:47.080 --> 00:11:50.360
it's setting us up for some truly spectacular events in

191
00:11:50.399 --> 00:11:54.679
twenty twenty six, including a total solar eclipse visible from

192
00:11:54.720 --> 00:11:59.720
Spain in August, something eclipse chasers are already eagerly anticipating.

193
