00:00:00.240 --> 00:00:03.680
Welcome to Astronomy Daily, your daily dose of space and
2
00:00:03.720 --> 00:00:07.240
astronomy news. I'm your host, Anna, and we've got an
3
00:00:07.320 --> 00:00:10.439
absolutely packed show for you today with some incredible developments
4
00:00:10.480 --> 00:00:13.759
from across the space sector. We'll be diving into Europe's
5
00:00:13.759 --> 00:00:16.960
triumphant return to space with the Vegas Sea rocket launch,
6
00:00:17.440 --> 00:00:21.800
unpacking NASA's latest timeline adjustments for their ambitious Artemis Moon missions,
7
00:00:22.199 --> 00:00:25.320
and exploring fascinating new evidence that suggests we might have
8
00:00:25.359 --> 00:00:28.519
a mysterious Planet X lurking in the outer reaches of
9
00:00:28.559 --> 00:00:32.799
our Solar system. We've also got some groundbreaking observations from
10
00:00:32.840 --> 00:00:36.159
the Hubble Space Telescope that's given us our closest ever
11
00:00:36.200 --> 00:00:40.000
look at Aquasar, plus exciting news about the Curiosity rovers
12
00:00:40.119 --> 00:00:44.320
next mission, targeting some intriguing spiderweb formations on Mars. And
13
00:00:44.399 --> 00:00:47.640
we'll round things off with crucial findings from NASA's investigation
14
00:00:47.759 --> 00:00:51.679
into the Artemis heat shield performance. So strap in for
15
00:00:51.759 --> 00:00:55.320
another fascinating journey through the latest developments in space exploration
16
00:00:55.439 --> 00:01:01.359
and astronomical discoveries. First up, some good news. Europe's space
17
00:01:01.399 --> 00:01:05.079
program has just achieved a significant milestone with the successful
18
00:01:05.159 --> 00:01:08.040
launch of the Vegas Sea rocket from the Kuru Spaceport
19
00:01:08.120 --> 00:01:11.599
in French Guiana. This marks a triumphant return to flight
20
00:01:11.640 --> 00:01:14.640
for the Italian built launcher after a two year hiatus
21
00:01:14.680 --> 00:01:18.040
following a failed mission in December twenty twenty two. The
22
00:01:18.120 --> 00:01:21.560
rocket blasted off at six twenty pm Local time, carrying
23
00:01:21.640 --> 00:01:24.719
the Sentinel one Sea satellite, a crucial component of the
24
00:01:24.760 --> 00:01:29.760
European Union's Copernicus Earth observation program. This successful launch represents
25
00:01:29.799 --> 00:01:33.319
a critical step in securing Europe's independent access to space,
26
00:01:34.000 --> 00:01:37.480
especially important given recent geopolitical challenges that have limited the
27
00:01:37.519 --> 00:01:42.920
continent's launch options. The mission's success is particularly noteworthy as
28
00:01:42.959 --> 00:01:46.000
Europe has faced several setbacks in its space program recently.
29
00:01:46.879 --> 00:01:49.879
The previous Vegas Sea failure had grounded the entire fleet
30
00:01:50.239 --> 00:01:53.439
when an anomaly destroyed two Earth imaging satellites just two
31
00:01:53.480 --> 00:01:56.439
and a half minutes into flight. This return to service
32
00:01:56.519 --> 00:02:01.200
demonstrates the resilience and determination of Europe's space sector. Looking ahead,
33
00:02:01.599 --> 00:02:04.239
Vegas C is set to play an increasingly important role
34
00:02:04.280 --> 00:02:08.400
in Europe's space strategy. Following Russia's invasion of Ukraine, the
35
00:02:08.479 --> 00:02:11.919
EU was forced to stop using Russian Soyuz vehicles, making
36
00:02:11.960 --> 00:02:15.599
the successful operation of platforms like vegas c even more crucial.
37
00:02:16.199 --> 00:02:19.439
Starting from twenty twenty five, Italy's Avio will take over
38
00:02:19.479 --> 00:02:22.719
the marketing of Vegacy launches, marking a new chapter in
39
00:02:22.759 --> 00:02:27.479
European space operations. The Sentinel one CE satellite, now heading
40
00:02:27.520 --> 00:02:31.000
to its seven hundred kilometer orbit, will join an impressive
41
00:02:31.039 --> 00:02:36.319
constellation of Earth observation satellites, expanding our planet's most extensive
42
00:02:36.400 --> 00:02:40.000
radar imaging network. This system plays a vital role in
43
00:02:40.080 --> 00:02:43.439
monitoring our environment, from tracking the climate to supporting disaster
44
00:02:43.560 --> 00:02:47.879
response efforts. Next, some not so good news. In a
45
00:02:47.919 --> 00:02:51.319
significant announcement today, NASA has revealed further delays to its
46
00:02:51.360 --> 00:02:55.159
ambitious Artemis program, pushing back the timeline for humanity's return
47
00:02:55.199 --> 00:02:58.039
to the Moon. The next Artemis mission, which will send
48
00:02:58.080 --> 00:03:01.400
astronauts around the Moon without landing, has been rescheduled from
49
00:03:01.479 --> 00:03:05.439
September twenty twenty five to April twenty twenty six. The
50
00:03:05.479 --> 00:03:08.599
subsequent mission, aiming to land astronauts on the lunar surface,
51
00:03:09.039 --> 00:03:12.719
is now targeted for mid twenty twenty seven. These delays
52
00:03:12.759 --> 00:03:17.240
stem from crucial safety considerations, particularly regarding the Orion spacecraft's
53
00:03:17.240 --> 00:03:20.360
heat shield. During the Artemis one test flight in twenty
54
00:03:20.400 --> 00:03:24.159
twenty two, the heat shield experienced unexpected cracking and partial
55
00:03:24.159 --> 00:03:28.240
erosion during re entry into Earth's atmosphere. While NASA officials
56
00:03:28.280 --> 00:03:31.439
stress that astronauts would have been safe had they been aboard,
57
00:03:31.560 --> 00:03:35.000
the agency is taking extra precautions to ensure crue safety
58
00:03:35.000 --> 00:03:38.680
for future missions. I'll have some more on this shortly. Also,
59
00:03:39.000 --> 00:03:42.560
the financial scope of the Artemis program is substantial, with
60
00:03:42.800 --> 00:03:47.039
estimated costs reaching ninety three billion dollars through twenty twenty five.
61
00:03:48.000 --> 00:03:52.280
Despite these delays, NASA Administrator Bill Nelson emphasized that the
62
00:03:52.360 --> 00:03:55.599
revised timeline still puts the United States well ahead of
63
00:03:55.719 --> 00:03:59.120
China's announced intention to land on the lunar surface by
64
00:03:59.120 --> 00:04:04.360
twenty thirty, maintaining America's leadership in space exploration. The technical
65
00:04:04.360 --> 00:04:06.759
team has decided to keep the current heat shield design
66
00:04:06.800 --> 00:04:09.719
for the next mission, but will modify the capsule's return
67
00:04:09.800 --> 00:04:14.560
trajectory to prevent similar issues future missions Beyond Artemis, The
68
00:04:14.560 --> 00:04:18.720
second will feature an upgraded heat shield design. While replacing
69
00:04:18.759 --> 00:04:21.920
the current heat shield might have provided additional safety margins,
70
00:04:22.319 --> 00:04:24.480
it would have resulted in an even longer delay of
71
00:04:24.519 --> 00:04:28.839
at least a year. These setbacks highlight the complex challenges
72
00:04:28.879 --> 00:04:33.000
of modern space exploration, but they also demonstrate NASA's unwavering
73
00:04:33.000 --> 00:04:37.079
commitment to crue safety. The Artemis program remains the flagship
74
00:04:37.120 --> 00:04:39.720
American effort to not only return humans to the Moon,
75
00:04:40.160 --> 00:04:42.839
but also to establish permanent lunar bases that will serve
76
00:04:42.879 --> 00:04:47.959
as stepping stones for eventual human missions to Mars. Next up,
77
00:04:48.519 --> 00:04:52.600
are we a step closer to solving this mystery? For decades,
78
00:04:53.079 --> 00:04:55.920
the idea of an undiscovered planet lurking in the outer
79
00:04:56.000 --> 00:05:00.920
reaches of our Solar System has captured imaginations. Now, exciting
80
00:05:00.959 --> 00:05:05.519
new research from Princeton University has significantly boosted the likelihood
81
00:05:05.759 --> 00:05:10.720
that this mysterious planet X actually exists. The studies findings
82
00:05:10.759 --> 00:05:14.160
suggest we might be closer than ever to confirming one
83
00:05:14.160 --> 00:05:18.879
of astronomy's most intriguing possibilities. The evidence comes from studying
84
00:05:18.879 --> 00:05:22.439
the orbits of objects in the outer Solar System, specifically
85
00:05:22.560 --> 00:05:26.480
trans Neptunian objects or Kuiper Belt objects. What makes this
86
00:05:26.600 --> 00:05:31.480
research particularly compelling is its expanded scope. While previous studies
87
00:05:31.480 --> 00:05:34.879
focused on just eleven of the most distant objects, the
88
00:05:34.920 --> 00:05:38.879
Princeton team's analysis included fifty one objects, providing a much
89
00:05:38.879 --> 00:05:43.680
more robust statistical foundation. The results are striking The team
90
00:05:43.720 --> 00:05:46.199
found that there's only a one in one thousand chance
91
00:05:46.560 --> 00:05:50.160
that the unusual alignment of these objects' orbits is random.
92
00:05:51.120 --> 00:05:55.040
This strongly suggests the presence of a massive body influencing
93
00:05:55.079 --> 00:05:59.439
their movements through gravitational forces. Think of it like seeing
94
00:05:59.519 --> 00:06:02.319
multiple boats all being pulled in the same direction by
95
00:06:02.319 --> 00:06:05.920
an unseen current. It's a clear sign that something significant
96
00:06:05.959 --> 00:06:09.480
is affecting their paths. The study also gives us our
97
00:06:09.480 --> 00:06:11.839
best picture yet of what Planet X might be like.
98
00:06:12.639 --> 00:06:15.519
The data suggests it's about four point four times the
99
00:06:15.560 --> 00:06:18.360
mass of Earth, making it either a super Earth or
100
00:06:18.399 --> 00:06:23.079
a mini Neptune. This hypothetical planet would follow an elliptical orbit,
101
00:06:23.199 --> 00:06:26.720
more aligned with the known planets than previously thought, though
102
00:06:26.759 --> 00:06:30.839
pinpointing its exact location remains challenging since it could be
103
00:06:30.920 --> 00:06:35.079
anywhere along its orbital path. The hunt for Planet X
104
00:06:35.240 --> 00:06:38.439
isn't just about adding another world to our Solar System map.
105
00:06:38.959 --> 00:06:43.480
If confirmed, its discovery would revolutionize our understanding of how
106
00:06:43.519 --> 00:06:47.839
our cosmic neighborhood formed and evolved. With the Versi Reuben
107
00:06:47.879 --> 00:06:51.759
Observatory coming online next year, equipped with the world's largest
108
00:06:51.759 --> 00:06:55.480
camera for astronomical observations, we might be just months away
109
00:06:55.480 --> 00:07:00.480
from finally spotting this elusive world. In a remarkable achievement,
110
00:07:00.680 --> 00:07:03.680
NASA's Hubble Space Telescope has given us our closest look
111
00:07:03.720 --> 00:07:06.600
ever into the heart of a quasar, peering deeper than
112
00:07:06.600 --> 00:07:09.959
ever before into one of the universe's most energetic phenomena.
113
00:07:10.519 --> 00:07:13.720
The observations focused on Quasar three C two hundred and
114
00:07:13.759 --> 00:07:17.160
seventy three, which holds the distinction of being the first
115
00:07:17.279 --> 00:07:21.759
quasar ever identified back in nineteen sixty three. What makes
116
00:07:21.759 --> 00:07:26.319
this observation truly groundbreaking is Hubble's ability to overcome the
117
00:07:26.399 --> 00:07:30.160
intense glare of the quaser. Imagine trying to spot an
118
00:07:30.279 --> 00:07:33.399
ant crawling on the rim of a car headlight while
119
00:07:33.399 --> 00:07:37.560
staring directly into the beam. The Telescope Space Telescope Imaging
120
00:07:37.600 --> 00:07:42.360
spectrograph acted like a celestial coronagraph, blocking out the quasar's
121
00:07:42.399 --> 00:07:45.439
overwhelming brightness, much like the Moon blocks the Sun during
122
00:07:45.439 --> 00:07:49.639
a solar eclipse. The resulting images reveal what scientists describe
123
00:07:49.720 --> 00:07:54.839
as weird things in the quasar's immediate surroundings. Within just
124
00:07:54.879 --> 00:07:58.600
sixteen thousand light years of the central black hole, researchers
125
00:07:58.639 --> 00:08:03.079
have spotted various mysterious blobs and an L shaped filamentary structure.
126
00:08:03.680 --> 00:08:06.560
Some of these objects might be smaller galaxies being pulled
127
00:08:06.600 --> 00:08:10.120
into the quasar's monstrous black hole, providing the fuel that
128
00:08:10.240 --> 00:08:15.160
powers its incredible luminosity. The team also made fascinating discoveries
129
00:08:15.160 --> 00:08:18.839
about the quasar's jet, a massive stream of material stretching
130
00:08:18.839 --> 00:08:22.399
and astounding three hundred thousand light years across space, moving
131
00:08:22.439 --> 00:08:26.360
at nearly the speed of light. By comparing observations taking
132
00:08:26.399 --> 00:08:29.879
twenty two years apart, they found that the jet actually
133
00:08:29.959 --> 00:08:34.000
accelerates as it moves farther from the black hole. This
134
00:08:34.240 --> 00:08:37.720
unprecedented view of three C two hundred and seventy three,
135
00:08:38.240 --> 00:08:41.919
located two point five billion light years away, is helping
136
00:08:41.960 --> 00:08:45.080
bridge our understanding between what we see in radio observations
137
00:08:45.559 --> 00:08:49.919
and larger scale optical imaging. It's offering crucial insights into
138
00:08:49.919 --> 00:08:53.120
how these cosmic lighthouses interact with their host galaxies and
139
00:08:53.200 --> 00:08:57.320
shape the evolution of the universe around them. Let's change
140
00:08:57.320 --> 00:09:01.360
gears and get Amar's update. NASA's Intrepid Curiosity Rover is
141
00:09:01.360 --> 00:09:04.039
gearing up for a fascinating new chapter in its already
142
00:09:04.080 --> 00:09:08.639
remarkable mission on Mars. After successfully wrapping up its exploration
143
00:09:08.720 --> 00:09:12.519
of the getis Vallis region, where it made several significant discoveries,
144
00:09:12.879 --> 00:09:16.480
including pure sulfur crystals and ancient lake bed formations. The
145
00:09:16.600 --> 00:09:20.720
rover is now setting its sights on something truly extraordinary,
146
00:09:20.759 --> 00:09:25.000
massive spiderweb like structures that stretch across the Martian surface.
147
00:09:25.559 --> 00:09:29.399
These peculiar formations, known as the box work, span an
148
00:09:29.399 --> 00:09:32.919
incredible six to twelve miles across and represent one of
149
00:09:32.960 --> 00:09:37.519
the most intriguing geological features ever identified on Mars. While
150
00:09:37.600 --> 00:09:40.799
similar structures exist on Earth in places like wind Cave
151
00:09:40.960 --> 00:09:44.519
National Park in South Dakota, they typically only extend a
152
00:09:44.519 --> 00:09:48.600
few feet, the Martian versions dwarf their terrestrial cousins by
153
00:09:48.679 --> 00:09:52.200
orders of magnitude. The boxwork formations are believed to have
154
00:09:52.279 --> 00:09:55.879
formed through a process involving mineral rich water, much like
155
00:09:55.919 --> 00:10:00.320
their Earth counterparts. As ancient waters carrying dissolved minerals seeped
156
00:10:00.399 --> 00:10:04.399
through cracks in the Martian rock, they left behind crystalline deposits.
157
00:10:05.039 --> 00:10:08.559
Over time, as the surrounding rock eroded away, these more
158
00:10:08.600 --> 00:10:12.600
resistant mineral veins remained, creating the distinctive weblike pattern we
159
00:10:12.639 --> 00:10:16.639
see today. What makes these structures particularly exciting for scientists
160
00:10:17.120 --> 00:10:20.519
is their potential to reveal new insights about Mars's watery past.
161
00:10:21.519 --> 00:10:25.080
The minerals preserved in these ancient formations could tell us
162
00:10:25.120 --> 00:10:28.600
not just about the chemistry of Mars's ancient waters, but
163
00:10:28.679 --> 00:10:32.559
potentially about whether the environment might have once been suitable
164
00:10:32.559 --> 00:10:36.480
for microbial life. The mineral composition of these structures could
165
00:10:36.519 --> 00:10:42.679
mirror similar environments on early Earth where microorganisms thrived. Curiosity
166
00:10:42.720 --> 00:10:46.120
won't reach these remarkable features until early twenty twenty five,
167
00:10:46.759 --> 00:10:50.039
but the anticipation among the science team is already building.
168
00:10:50.639 --> 00:10:54.519
This investigation promises to add another fascinating chapter to our
169
00:10:54.600 --> 00:10:58.600
understanding of Mars's geological history and its potential for having
170
00:10:58.639 --> 00:11:03.639
once harbored life. And now some more Artemis news. After
171
00:11:03.679 --> 00:11:07.759
extensive investigation, NASA has finally uncovered the root cause of
172
00:11:07.799 --> 00:11:11.360
the unexpected heat shield damage observed during the Artemis one mission.
173
00:11:11.840 --> 00:11:16.039
The investigation revealed a fascinating technical challenge that occurred during
174
00:11:16.080 --> 00:11:20.320
the spacecraft's revolutionary skip re entry maneuver. The issue stemmed
175
00:11:20.320 --> 00:11:23.159
from gases that built up inside the heat shield's protective
176
00:11:23.159 --> 00:11:27.159
avcoat material during re entry. Normally, these gases should have
177
00:11:27.240 --> 00:11:31.360
vented and dissipated, but they became trapped, creating pressure that
178
00:11:31.440 --> 00:11:35.000
caused cracking and led to pieces of charred material breaking
179
00:11:35.039 --> 00:11:39.200
away in several locations. What's particularly interesting is that this
180
00:11:39.240 --> 00:11:43.559
phenomenon wasn't captured in pre flight testing. The ground tests
181
00:11:43.639 --> 00:11:46.600
used much higher heating rates than what the spacecraft actually
182
00:11:46.639 --> 00:11:51.360
experienced during its return. Under those more intense conditions, the
183
00:11:51.440 --> 00:11:55.559
material behaved as expected, but the actual gentler heating during
184
00:11:55.639 --> 00:11:59.720
artemis the Fort's re entry created a different reaction, slowing
185
00:11:59.720 --> 00:12:03.720
down the formation of protective char while still generating gases
186
00:12:03.759 --> 00:12:07.600
within the material. Despite these findings, there's good news for
187
00:12:07.639 --> 00:12:12.080
future missions. The investigation confirmed that even with the unexpected
188
00:12:12.120 --> 00:12:17.000
heat shield behavior, the spacecraft's internal temperature remained remarkably stable
189
00:12:17.080 --> 00:12:20.679
in the mid seventies fahrenheit. Had astronauts been aboard, they
190
00:12:20.679 --> 00:12:23.679
would have remained perfectly safe throughout the re entry process.
191
00:12:24.279 --> 00:12:28.519
NASA's engineers have already identified solutions for future missions. They
192
00:12:28.559 --> 00:12:31.039
discovered that areas of the heat shield that were naturally
193
00:12:31.080 --> 00:12:34.919
more permeable didn't experience the same cracking issues, as the
194
00:12:34.960 --> 00:12:39.159
gases could escape more easily. This insight is driving improvements
195
00:12:39.159 --> 00:12:43.519
in the manufacturing process to ensure more consistent permeability in
196
00:12:43.600 --> 00:12:47.519
future heat shields. These findings represent a perfect example of
197
00:12:47.559 --> 00:12:50.519
why we conduct uncrude test flights. They allow us to
198
00:12:50.559 --> 00:12:53.919
identify and solve potential issues before putting astronauts at risk,
199
00:12:54.440 --> 00:13:00.320
ultimately making future crude missions safer and more reliable. Up
