1
00:00:00.240 --> 00:00:03.040
Welcome to Astronomy Daily. I'm Ana and we've got an

2
00:00:03.080 --> 00:00:06.400
absolutely packed show for you today with some fascinating developments

3
00:00:06.440 --> 00:00:09.480
from across the space sector. We'll be diving into the

4
00:00:09.560 --> 00:00:13.480
latest shakeup in European space cooperation, where Italy is making

5
00:00:13.519 --> 00:00:16.920
some interesting moves that could reshape the continent's space industry.

6
00:00:17.760 --> 00:00:19.839
I'll also bring you up to speed on our colleagues

7
00:00:19.960 --> 00:00:23.760
up on the International Space Station where two NASA astronauts

8
00:00:23.760 --> 00:00:26.879
are taking their extended stay and stride. Plus, we'll look

9
00:00:26.879 --> 00:00:29.440
at why Blue Origin had to delay the debut launch

10
00:00:29.440 --> 00:00:32.759
of their massive new Glen rocket. Then we'll explore some

11
00:00:32.840 --> 00:00:36.600
incredible new images from Beppy Columbo's final flyby of Mercury,

12
00:00:37.079 --> 00:00:40.000
and wrap up with a mind blowing discovery about Jupiter's

13
00:00:40.000 --> 00:00:43.399
clouds that's completely changing what we thought we knew about

14
00:00:43.439 --> 00:00:46.439
the gas giant. Stay with me as we journey through

15
00:00:46.479 --> 00:00:50.960
these exciting stories in today's episode of Astronomy Daily. In

16
00:00:51.000 --> 00:00:55.200
a significant development for European space cooperation, the head of

17
00:00:55.240 --> 00:00:59.520
the European Space Agency has addressed growing concerns about potential

18
00:00:59.560 --> 00:01:04.319
fragmentation within the European space sector. This comes as Italy

19
00:01:04.439 --> 00:01:08.159
charts its own course in rocket operations and explores possible

20
00:01:08.159 --> 00:01:13.719
agreements with Elon Musk's Starlink satellite network. Italy's space company, Avio,

21
00:01:13.879 --> 00:01:16.560
is set to take control of Viga C rocket operations

22
00:01:16.599 --> 00:01:20.159
on behalf of ESA, effectively moving the Italian built rocket

23
00:01:20.200 --> 00:01:23.719
away from Europe's primary launch operator, are and E Space.

24
00:01:24.319 --> 00:01:27.840
At the same time, ROME is evaluating potential supply agreements

25
00:01:27.840 --> 00:01:32.879
with Starlink, with Musk expressing enthusiasm about providing Italy with

26
00:01:32.920 --> 00:01:37.439
what he calls the most secure and advanced connectivity. ESA

27
00:01:37.480 --> 00:01:40.480
Director General Joseph Aschbacher is keeping a watchful eye on

28
00:01:40.519 --> 00:01:45.239
these developments, particularly the balance between national and European space activities.

29
00:01:45.920 --> 00:01:49.719
While acknowledging that space is becoming increasingly strategic and important

30
00:01:50.079 --> 00:01:54.040
with investments on the rise, Ashbacher emphasizes the benefits of

31
00:01:54.040 --> 00:01:59.159
participating in European programs rather than purely national ones. This

32
00:01:59.200 --> 00:02:02.439
situation becomes even more intriguing when we consider the timing.

33
00:02:03.200 --> 00:02:06.920
These discussions about Italy's potential role with Starlink comes shortly

34
00:02:06.959 --> 00:02:10.919
after the European Commission announced funding for Iris II, their

35
00:02:10.960 --> 00:02:15.439
own satellite constellation designed to provide secure communications for European

36
00:02:15.439 --> 00:02:19.680
governments and agencies. Looking ahead to twenty twenty five, ESA

37
00:02:19.719 --> 00:02:24.520
has outlined ambitious launch plans despite recent setbacks. Their flagship

38
00:02:24.520 --> 00:02:27.360
Ariane six rocket is now scheduled for its next launch

39
00:02:27.360 --> 00:02:31.879
in February, with four more launches planned throughout the year. Meanwhile,

40
00:02:31.960 --> 00:02:34.719
the Vega SA rocket, which successfully returned to flight in

41
00:02:34.759 --> 00:02:38.120
December after a previous failure, is set to conduct four

42
00:02:38.199 --> 00:02:42.120
launches in twenty twenty five. The agency maintains that it

43
00:02:42.120 --> 00:02:45.639
will prioritize using European launchers now that they are available again.

44
00:02:46.520 --> 00:02:48.960
This marks a shift from recent years, when ESA had

45
00:02:48.960 --> 00:02:51.840
to rely on SpaceX's Falcon nine rockets during gaps in

46
00:02:51.919 --> 00:02:56.240
European launch capabilities. However, ESA will continue with one planned

47
00:02:56.240 --> 00:02:59.280
SpaceX launch, the Sentinel six B mission, which is being

48
00:02:59.360 --> 00:03:03.879
funded through now cooperation. Now an update from the ISS.

49
00:03:04.199 --> 00:03:07.520
Two NASA astronauts have found themselves in an unexpectedly extended

50
00:03:07.520 --> 00:03:10.639
stay aboard the International Space Station, but their spirits remain

51
00:03:10.719 --> 00:03:15.360
remarkably high. Butch Wilmore and Sunny Williams, who originally planned

52
00:03:15.360 --> 00:03:17.759
for just an eight day mission when they launched in

53
00:03:17.840 --> 00:03:20.639
June twenty twenty four, have turned what could have been

54
00:03:20.680 --> 00:03:25.800
a challenging situation into a testament to astronaut adaptability. When

55
00:03:25.840 --> 00:03:28.319
asked during a phone conference call earlier this week about

56
00:03:28.319 --> 00:03:32.319
feeling like castaways, a reference to the Tom Hanks film Sunny,

57
00:03:32.360 --> 00:03:36.680
Williams was quick to dismiss any such notion. While acknowledging

58
00:03:36.680 --> 00:03:40.039
their desire to eventually return home to their families, she

59
00:03:40.159 --> 00:03:43.599
emphasized their focus on the important work that still needs

60
00:03:43.599 --> 00:03:47.759
to be done aboard the station. This professional dedication showcases

61
00:03:47.800 --> 00:03:51.879
the true spirit of space exploration. Their extended mission hasn't

62
00:03:51.919 --> 00:03:55.400
been without its share of memorable moments. The astronauts have

63
00:03:55.479 --> 00:03:59.360
experienced several major events from their orbital perspective, including the

64
00:03:59.479 --> 00:04:03.599
US election, Thanksgiving, and Christmas. They've maintained their connection to

65
00:04:03.639 --> 00:04:07.080
life on Earth, with Wilmore even managing to participate in

66
00:04:07.120 --> 00:04:09.800
important moments of his daughter's final year of high school,

67
00:04:10.479 --> 00:04:14.199
albeit from two hundred and fifty miles above. The station

68
00:04:14.319 --> 00:04:18.279
has remained well supplied, with recent cargo deliveries bringing essential

69
00:04:18.279 --> 00:04:22.839
supplies including food, water, oxygen, and even special items to

70
00:04:22.839 --> 00:04:26.480
help the crew celebrate the holidays. Far from being idle,

71
00:04:26.759 --> 00:04:30.439
both astronauts have fully integrated into the station's regular crew duties,

72
00:04:30.920 --> 00:04:34.560
taking on everything from routine maintenance to complex repair work.

73
00:04:35.319 --> 00:04:38.399
Looking ahead, Sunny Williams is preparing for her eighth spacewalk,

74
00:04:38.879 --> 00:04:43.399
an impressive milestone in her NASA career. During this upcoming EVA,

75
00:04:43.920 --> 00:04:46.720
she'll be working with another crew member to replace critical

76
00:04:46.759 --> 00:04:50.639
orientation equipment on the station's exterior, as well as conducting

77
00:04:50.680 --> 00:04:55.480
repairs on various instruments, including a telescope. This continued commitment

78
00:04:55.519 --> 00:04:59.240
to station maintenance and scientific work demonstrates how these astronauts

79
00:04:59.240 --> 00:05:03.680
have transformed an unexpected situation into an opportunity for extended

80
00:05:03.720 --> 00:05:08.360
contribution to space exploration. Now an update to a story

81
00:05:08.360 --> 00:05:11.519
we've been following this week in space launch news, Blue

82
00:05:11.519 --> 00:05:13.839
Origin has had to push back the debut launch of

83
00:05:13.879 --> 00:05:18.079
their impressive new Glen rocket. The postponement comes due to

84
00:05:18.160 --> 00:05:22.079
challenging weather conditions in the Atlantic Ocean, specifically rough seas

85
00:05:22.240 --> 00:05:26.000
that could impact the rocket's planned booster landing. The launch,

86
00:05:26.360 --> 00:05:29.680
originally set for early Friday morning, has been rescheduled for

87
00:05:29.759 --> 00:05:32.399
Sunday at one a m. Eastern time from Cape Canaveral

88
00:05:32.439 --> 00:05:36.199
Space Force Station in Florida. This massive vehicle stands an

89
00:05:36.199 --> 00:05:39.560
impressive three hundred and twenty feet tall and represents Blue

90
00:05:39.600 --> 00:05:43.399
Origins first venture into orbital class rockets. What makes New

91
00:05:43.439 --> 00:05:47.759
Glen particularly interesting is its reusable first stage, designed to

92
00:05:47.759 --> 00:05:50.480
return to Earth and land on a specialized vessel in

93
00:05:50.519 --> 00:05:55.040
the Atlantic. The landing ship, named Jacqueline, after Jeff Bezos's mother,

94
00:05:55.399 --> 00:05:58.199
will serve as the touchdown point for these returning boosters.

95
00:05:59.199 --> 00:06:02.160
While Blue Origin and acknowledges the ambitious nature of attempting

96
00:06:02.160 --> 00:06:05.240
a booster landing on their very first flight, they're committed

97
00:06:05.240 --> 00:06:08.639
to giving it their best shot. This approach to reusability

98
00:06:08.680 --> 00:06:12.519
isn't just about technical achievement, it's central to their business model.

99
00:06:13.000 --> 00:06:15.639
Each New Glen first stage is engineered to fly at

100
00:06:15.720 --> 00:06:19.680
least twenty five times, which could significantly reduce launch costs

101
00:06:19.720 --> 00:06:23.480
for future missions. The rocket already has an impressive lineup

102
00:06:23.560 --> 00:06:27.120
of contracted missions waiting in the wings, including plans to

103
00:06:27.199 --> 00:06:30.319
launch missions to Mars for NASA and a series of

104
00:06:30.360 --> 00:06:34.959
Amazon's Kuyper Internet satellites. This makes the successful debut of

105
00:06:35.040 --> 00:06:38.360
New Glen crucial not just for Blue Origin, but for

106
00:06:38.399 --> 00:06:42.319
their commercial and government partners as well. Should Sunday's launch

107
00:06:42.319 --> 00:06:46.000
attempt face additional delays, Blue Origin has secured a launch

108
00:06:46.000 --> 00:06:50.720
window extending through January sixteenth. This flexibility ensures they can

109
00:06:50.759 --> 00:06:53.399
wait for optimal conditions to give their new rocket the

110
00:06:53.439 --> 00:06:56.879
best possible chance of success in both its primary mission

111
00:06:56.959 --> 00:07:01.319
and the ambitious booster recovery attempt. Moving on now to

112
00:07:01.360 --> 00:07:04.920
a space mission that's really kicking goals, The BEPI Columbo

113
00:07:04.959 --> 00:07:09.120
spacecraft has just completed a remarkable milestone, making its sixth

114
00:07:09.160 --> 00:07:12.120
and final flyby of Mercury before its main mission begins

115
00:07:12.160 --> 00:07:16.120
next year. During this close encounter, the spacecraft came within

116
00:07:16.240 --> 00:07:19.120
just one hundred and eighty five miles of Mercury's surface,

117
00:07:19.720 --> 00:07:22.720
giving us some incredible new views of the Solar System's

118
00:07:22.759 --> 00:07:28.160
smallest planet. The images captured during this flyby are particularly fascinating,

119
00:07:28.639 --> 00:07:33.199
offering us detailed glimpses of Mercury's mysterious surface features. One

120
00:07:33.240 --> 00:07:37.399
of the most intriguing discoveries involves the planet's permanently shadowed craters.

121
00:07:38.120 --> 00:07:41.879
Despite Mercury's proximity to the Sun, these deep craters rank

122
00:07:41.920 --> 00:07:45.199
among the coldest places in our entire Solar System, and

123
00:07:45.319 --> 00:07:49.519
scientists believe they might harbor water ice. The spacecraft's monitoring

124
00:07:49.560 --> 00:07:53.800
cameras revealed striking contrasts between Mercury's dark surface and bright

125
00:07:53.839 --> 00:07:59.240
features that indicate recent geological activity. The Nathae facula, for instance,

126
00:07:59.519 --> 00:08:02.360
stands out as the remnant of the largest known volcanic

127
00:08:02.399 --> 00:08:05.839
explosion on Mercury, with a central vent spanning twenty five

128
00:08:05.920 --> 00:08:09.680
miles in volcanic deposits extending nearly two hundred miles in diameter.

129
00:08:10.680 --> 00:08:14.279
The images also showcased Mercury's vast volcanic plains, known as

130
00:08:14.319 --> 00:08:18.040
the Borealis Planetia, formed by massive lava flows roughly three

131
00:08:18.079 --> 00:08:21.600
point seven billion years ago. These ancient flows created smooth

132
00:08:21.639 --> 00:08:24.879
regions across much of Mercury's surface, later marked by wrinkles

133
00:08:24.959 --> 00:08:28.759
as the planet's interior cooled and contracted. Within these planes,

134
00:08:29.120 --> 00:08:33.120
we can see numerous impact craters, including the massive Colorus Basin,

135
00:08:33.480 --> 00:08:37.039
which stretches over nine hundred and thirty miles wide. One

136
00:08:37.120 --> 00:08:40.080
particularly unexpected feature caught in the new images is a

137
00:08:40.080 --> 00:08:45.000
distinctive boomerang shaped lava flow near the Coloris basin. This formation,

138
00:08:45.360 --> 00:08:48.639
connected to a deep trough, presents an intriguing puzzle that

139
00:08:48.679 --> 00:08:52.399
scientists hope to solve when BEPI Colombo begins its primary mission.

140
00:08:53.240 --> 00:08:56.360
The spacecraft is scheduled to enter Mercury's orbit on November

141
00:08:56.399 --> 00:08:59.720
twenty first, twenty twenty six, when it will begin its

142
00:08:59.759 --> 00:09:03.440
des tailed investigation of these and other mysteries about our

143
00:09:03.440 --> 00:09:08.639
Solar System's innermost planet. Now onto the amazing discovery of

144
00:09:08.679 --> 00:09:12.080
the day. Our understanding of Jupiter's clouds has just been

145
00:09:12.120 --> 00:09:16.600
completely transformed thanks to a groundbreaking collaboration between amateur and

146
00:09:16.639 --> 00:09:22.039
professional astronomers. For decades, scientists believed Jupiter's visible clouds were

147
00:09:22.039 --> 00:09:26.440
primarily composed of ammonia ice. However, new research published in

148
00:09:26.440 --> 00:09:30.000
the Journal of Geophysical Research has revealed something entirely different.

149
00:09:30.480 --> 00:09:34.200
These clouds are actually made of ammonium hydrosulfide mixed with smog.

150
00:09:34.759 --> 00:09:38.440
This fascinating discovery began with amateur astronomer doctor Stephen Hill

151
00:09:38.480 --> 00:09:42.799
from Colorado, who demonstrated that using commercially available telescopes with

152
00:09:42.840 --> 00:09:47.200
specialized filters could effectively measure ammonia levels and pressure at

153
00:09:47.279 --> 00:09:52.759
Jupiter's cloud tops. His observations revealed something unexpected. These clouds

154
00:09:52.799 --> 00:09:55.840
were simply too deep in Jupiter's warm atmosphere to be

155
00:09:55.879 --> 00:10:00.559
made of ammonia ice as previously thought. Professor Patrick Irwin

156
00:10:00.639 --> 00:10:05.000
from Oxford University took this research further, applying Hill's methods

157
00:10:05.039 --> 00:10:09.440
to observations from the very large telescope in Chile. Using

158
00:10:09.440 --> 00:10:13.799
spectroscopic analysis, his team confirmed that Jupiter's main cloud deck

159
00:10:13.919 --> 00:10:17.080
exists in a region of higher pressure and temperature than

160
00:10:17.159 --> 00:10:20.480
previously believed. The conditions there are simply too warm for

161
00:10:20.480 --> 00:10:24.360
ammonia to condense into ice, pointing to ammonium hydrosulfide as

162
00:10:24.399 --> 00:10:29.120
the primary component instead. The team suggests that in Jupiter's atmosphere,

163
00:10:29.399 --> 00:10:33.159
when ammonia rich air rises, the ammonia is either destroyed

164
00:10:33.279 --> 00:10:36.360
or mixed with photochemical products faster than ice can form.

165
00:10:37.000 --> 00:10:40.000
This process explains the distinctive red and brown colors we

166
00:10:40.039 --> 00:10:43.279
see in Jupiter's clouds. They're actually a mixture of ammonium

167
00:10:43.360 --> 00:10:49.879
hydrosulfide and smog like compounds created by sunlight induced chemical reactions. Interestingly,

168
00:10:50.399 --> 00:10:53.240
this research method has proven so effective that it's now

169
00:10:53.279 --> 00:10:56.720
being applied to Saturn as well, where similar processes appear

170
00:10:56.759 --> 00:10:59.879
to be at work. This discovery not only changes our

171
00:11:00.039 --> 00:11:03.759
fundamental understanding of Jupiter's atmosphere, but also opens up new

172
00:11:03.759 --> 00:11:08.279
opportunities for citizen scientists to contribute to planetary research. Using

173
00:11:08.360 --> 00:11:12.159
these relatively simple techniques, amateur astronomers can now track atmospheric

174
00:11:12.240 --> 00:11:15.720
changes across Jupiter's bands storms and even its famous great

175
00:11:15.759 --> 00:11:20.799
red spot. Well, that wraps up another fascinating day of

176
00:11:20.840 --> 00:11:25.399
space exploration and discovery, from the changing landscape of European

177
00:11:25.440 --> 00:11:29.360
space cooperation to the resilient spirits of our astronauts on

178
00:11:29.399 --> 00:11:33.279
the ISS, from Blue Origin's careful approach to their New

179
00:11:33.320 --> 00:11:37.480
Glen launch, to Bepy Columbo's final rendezvous with Mercury, and

180
00:11:37.559 --> 00:11:42.080
of course that remarkable revelation about Jupiter's clouds. We've covered

181
00:11:42.159 --> 00:11:45.519
