00:00:00.200 --> 00:00:03.560
Welcome to Astronomy Daily. I'm excited to bring you today's
2
00:00:03.640 --> 00:00:07.040
fascinating roundup of space and astronomy news. We've got an
3
00:00:07.040 --> 00:00:10.400
incredible lineup of stories that showcase just how rapidly our
4
00:00:10.480 --> 00:00:14.560
understanding of the Cosmos continues to evolve. Coming up, we'll
5
00:00:14.560 --> 00:00:17.320
dive into a breakthrough discovery about mysterious gullies on the
6
00:00:17.359 --> 00:00:21.359
asteroid Vesta, where NASA scientists have uncovered evidence of ancient
7
00:00:21.359 --> 00:00:24.719
brine flows carved by meteoroid impacts. We'll also look at
8
00:00:24.800 --> 00:00:28.039
NASA's ambitious plans for the next generation of Mars helicopters,
9
00:00:28.399 --> 00:00:32.719
building on the remarkable success of ingenuity in deep space
10
00:00:32.759 --> 00:00:35.799
communication news, there's a major upgrade coming to NASA's deep
11
00:00:35.840 --> 00:00:38.960
space network that will revolutionize how we stay connected with
12
00:00:39.000 --> 00:00:44.200
our far flung explorers. Plus, we'll preview some spectacular celestial
13
00:00:44.240 --> 00:00:47.399
events coming our way in twenty twenty five and explore
14
00:00:47.439 --> 00:00:50.399
how meteor showers might help us protect Earth from potentially
15
00:00:50.439 --> 00:00:54.000
hazardous comments. Stay with us as we journey through these
16
00:00:54.039 --> 00:00:58.119
remarkable developments in space exploration and discovery. There's a lot
17
00:00:58.119 --> 00:01:00.640
to cover, so let's get started with some great news
18
00:01:00.640 --> 00:01:05.680
from NASA. Scientists have made a fascinating breakthrough in understanding
19
00:01:05.680 --> 00:01:09.319
the mysterious gullies on the asteroid Vesta, and it's all
20
00:01:09.400 --> 00:01:13.959
thanks to some innovative laboratory experiments. These deep channels have
21
00:01:14.079 --> 00:01:17.760
long puzzled researchers who studied images from NASA's don mission,
22
00:01:18.200 --> 00:01:20.719
but now we have compelling evidence for how they formed.
23
00:01:21.200 --> 00:01:24.439
The key to this discovery lies in something surprisingly familiar,
24
00:01:24.879 --> 00:01:29.560
table salt or sodium chloride. Using specialized equipment to recreate
25
00:01:29.640 --> 00:01:34.359
Vesta's extreme conditions, researchers found that when meteoroids impact the
26
00:01:34.439 --> 00:01:38.159
asteroid's surface, they can trigger flows of salty water that
27
00:01:38.239 --> 00:01:42.680
carve these distinctive channels before freezing. What makes this particularly
28
00:01:42.719 --> 00:01:45.760
interesting is how the salt helps the water remain liquid
29
00:01:46.200 --> 00:01:50.400
long enough to create these features. In their experiments, scientists
30
00:01:50.400 --> 00:01:54.280
found that while pure water froze almost instantly in Vesta
31
00:01:54.400 --> 00:01:57.840
like conditions, briny water could continue flowing for at least
32
00:01:57.879 --> 00:02:01.159
an hour. This timing matches per perfectly with estimates of
33
00:02:01.159 --> 00:02:03.120
how long it would take to form the gullies we
34
00:02:03.159 --> 00:02:07.120
see on Vesta's surface. The research team used a specially
35
00:02:07.120 --> 00:02:11.280
designed chamber called Dusty the Dirty under vacuum simulation test
36
00:02:11.319 --> 00:02:16.080
bed for icy environments at NASA's Jet Propulsion Laboratory, they
37
00:02:16.120 --> 00:02:19.360
discovered that these briny flows develop a frozen lid on
38
00:02:19.400 --> 00:02:23.080
their surface, much like a lava tube on Earth. This
39
00:02:23.159 --> 00:02:27.240
frozen layer acts as insulation, protecting the flowing liquid underneath
40
00:02:27.360 --> 00:02:31.159
and allowing it to travel further before freezing completely. This
41
00:02:31.199 --> 00:02:34.800
discovery isn't just about solving a geological puzzle on one asteroid.
42
00:02:35.240 --> 00:02:38.319
It contributes to our broader understanding of how liquids behave
43
00:02:38.439 --> 00:02:42.479
on airless worlds throughout our Solar System. The findings align
44
00:02:42.520 --> 00:02:45.400
with other research about potential mud volcanoes on Mars and
45
00:02:45.680 --> 00:02:49.919
icy volcanoes on Jupiter's moon Europa, suggesting similar processes might
46
00:02:49.919 --> 00:02:54.400
be at work across different celestial bodies. What's particularly exciting
47
00:02:54.479 --> 00:02:57.599
is how this research builds on the original findings from
48
00:02:57.680 --> 00:03:01.199
NASA's Dawn mission, which first hint at the possibility of
49
00:03:01.280 --> 00:03:05.560
subsurface ice on Vesta. The new study not only explains
50
00:03:05.599 --> 00:03:09.639
how these gullies formed, but also provides valuable insights into
51
00:03:09.639 --> 00:03:14.120
the complex interplay between impacts ice and salt in shaping
52
00:03:14.120 --> 00:03:18.520
the surfaces of airless worlds throughout our Solar System. In
53
00:03:18.599 --> 00:03:22.639
more NASA News Today, Following the incredible success of Ingenuity,
54
00:03:23.120 --> 00:03:25.800
NASA has unveiled their vision for the next generation of
55
00:03:25.879 --> 00:03:30.479
Martian aerial exploration, the Mars Chopper. This ambitious new design
56
00:03:30.560 --> 00:03:34.479
represents a significant leap forward in our capability to explore
57
00:03:34.520 --> 00:03:37.919
the Red Planet from above. To appreciate just how far
58
00:03:38.000 --> 00:03:41.800
we've come, let's recall that Ingenuity made history in April
59
00:03:41.840 --> 00:03:44.879
twenty twenty one as the first aircraft to achieve powered
60
00:03:44.919 --> 00:03:49.080
flight on another world. What started as a technology demonstration
61
00:03:49.639 --> 00:03:53.719
has since completed an impressive sixty flights, proving that aerial
62
00:03:53.759 --> 00:03:57.800
exploration on Mars isn't just possible, it's incredibly valuable for
63
00:03:57.840 --> 00:04:02.560
future missions. Mars Chopper is dramatically larger than its predecessor,
64
00:04:02.919 --> 00:04:06.759
roughly the size of an suv. It features an innovative
65
00:04:06.800 --> 00:04:11.000
design with six rotors, each equipped with six blades. While
66
00:04:11.039 --> 00:04:14.000
these blades are actually smaller than those used on Ingenuity,
67
00:04:14.360 --> 00:04:18.319
their combined effect provides even greater lift capacity. This enhanced
68
00:04:18.360 --> 00:04:21.240
power allows the craft to carry up to five kilograms
69
00:04:21.240 --> 00:04:25.199
of scientific equipment and travel distances of up to three kilometers.
70
00:04:26.120 --> 00:04:29.519
Flying on Mars presents unique challenges that the design team,
71
00:04:29.759 --> 00:04:33.839
a collaboration between the Jet Propulsion Laboratory and Aims Research
72
00:04:33.879 --> 00:04:37.560
Center had to overcome the Martian atmosphere is less than
73
00:04:37.600 --> 00:04:41.439
one percent as dense as Earth's, requiring specially engineered rotor
74
00:04:41.480 --> 00:04:44.560
systems to generate sufficient lift. They also had to account
75
00:04:44.600 --> 00:04:48.560
for the planet's notorious dust storms, incorporating protective features to
76
00:04:48.639 --> 00:04:52.560
shield the craft's delicate mechanisms. This new vehicle isn't just
77
00:04:52.600 --> 00:04:57.720
about improved performance, It's about expanding our exploration capabilities. While
78
00:04:57.920 --> 00:05:01.120
ingenuity prove the concept, the Mar Chopper is designed to
79
00:05:01.160 --> 00:05:04.959
be a true scientific platform. Its payload capacity means it
80
00:05:04.959 --> 00:05:09.519
can carry sophisticated imaging equipment and analysis tools, enabling it
81
00:05:09.560 --> 00:05:13.639
to conduct detailed surveys and scientific investigations from the air.
82
00:05:14.839 --> 00:05:18.480
This aerial perspective will be invaluable for supporting both robotic
83
00:05:18.560 --> 00:05:23.120
and future human missions on Mars. Looking beyond Mars, this
84
00:05:23.199 --> 00:05:27.360
technology could revolutionize how we explore other worlds with atmospheres.
85
00:05:28.000 --> 00:05:31.399
The lessons learned from developing and operating these aircraft will
86
00:05:31.439 --> 00:05:35.360
be crucial for designing similar vehicles to explore places like Titan,
87
00:05:35.959 --> 00:05:39.759
Saturn's largest moon, where the dense atmosphere could make aerial
88
00:05:39.800 --> 00:05:44.759
exploration particularly effective and in more news from the Agency,
89
00:05:45.600 --> 00:05:48.639
NASA has achieved a major milestone in enhancing our deep
90
00:05:48.639 --> 00:05:52.519
space communication capabilities with the installation of a massive new
91
00:05:52.519 --> 00:05:56.800
antenna at the Goldstone Deep Space Communications Complex in California.
92
00:05:57.839 --> 00:06:02.120
Deep Space Station twenty three, as it's officially known, represents
93
00:06:02.120 --> 00:06:06.040
a significant upgrade to NASA's deep space network, the vital
94
00:06:06.079 --> 00:06:09.759
communication system that keeps US connected with spacecraft exploring the
95
00:06:09.800 --> 00:06:13.920
furthest reaches of our Solar system and beyond. The centerpiece
96
00:06:13.959 --> 00:06:17.120
of this new installation is its impressive one hundred thirty
97
00:06:17.120 --> 00:06:21.079
three ton reflector dish, measuring one hundred and twelve feet across.
98
00:06:21.759 --> 00:06:25.680
The construction process was a remarkable feat of engineering, requiring
99
00:06:25.759 --> 00:06:29.399
precise alignment of forty bolt holes as the massive structure
100
00:06:29.439 --> 00:06:32.639
was carefully lowered onto its sixty five foot high support platform.
101
00:06:33.920 --> 00:06:36.879
Engineers then added a sixteen and a half ton quadrupoed
102
00:06:36.920 --> 00:06:40.759
structure featuring a curved sub reflector that will help direct
103
00:06:40.839 --> 00:06:45.279
radio signals from deep space to the antenna's receivers. When
104
00:06:45.360 --> 00:06:48.839
it becomes operational in twenty twenty six, Deep Space Station
105
00:06:48.920 --> 00:06:52.920
twenty three will join an elite network of fifteen antennas worldwide,
106
00:06:53.240 --> 00:06:56.839
supporting missions like Perseverance on Mars, the Voyager probes at
107
00:06:56.839 --> 00:06:59.560
the edge of our Solar System, and upcoming ventures like
108
00:06:59.560 --> 00:07:03.120
the europe Clipper. This expansion couldn't come at a more
109
00:07:03.120 --> 00:07:07.199
crucial time, as NASA's deep space missions continue to multiply,
110
00:07:07.399 --> 00:07:10.600
from robotic explorers to human missions returning to the Moon
111
00:07:11.040 --> 00:07:15.839
and eventually heading to Mars. The Deep Space Network currently
112
00:07:15.839 --> 00:07:20.000
supports over forty missions, serving as humanity's primary link to
113
00:07:20.040 --> 00:07:24.319
our mechanical explorers traversing the Solar System. Whether it's receiving
114
00:07:24.399 --> 00:07:28.399
stunning images from the James Web Space Telescope, guiding rovers
115
00:07:28.439 --> 00:07:32.160
across the Martian landscape, or maintaining contact with the most
116
00:07:32.160 --> 00:07:36.759
distant human made objects in existence, this communication network is
117
00:07:36.959 --> 00:07:42.000
absolutely essential to our continued exploration of space. This upgrade
118
00:07:42.079 --> 00:07:45.720
represents more than just improved hardware. It's an investment in
119
00:07:45.759 --> 00:07:49.759
our future as a spacefaring civilization. As we push the
120
00:07:49.759 --> 00:07:53.199
boundaries of exploration further into our Solar System and beyond,
121
00:07:53.759 --> 00:07:59.279
having robust, reliable communication infrastructure becomes increasingly critical. Deep Space
122
00:07:59.279 --> 00:08:01.879

123
00:08:01.879 --> 00:08:05.839
the next generation of missions, maintaining our connection with spacecraft
124
00:08:05.839 --> 00:08:08.839
and astronauts as they venture deeper into the cosmic frontier.
125
00:08:10.399 --> 00:08:13.680
Space enthusiasts have an exciting year ahead in twenty twenty five,
126
00:08:14.120 --> 00:08:17.120
with numerous celestial events set to light up our skies.
127
00:08:18.439 --> 00:08:20.800
Let's start with what January has in store for us.
128
00:08:21.319 --> 00:08:24.079
The year kicks off with the quadranted meteor shower on
129
00:08:24.199 --> 00:08:27.639
January third, promising up to one hundred and twenty shooting
130
00:08:27.680 --> 00:08:32.919
stars per hour and the possibility of spectacular fireballs. Just
131
00:08:32.960 --> 00:08:36.200
a few days later, will witness Mars being occulted by
132
00:08:36.240 --> 00:08:40.519
the wolf moon on January thirteenth, followed by Mars reaching
133
00:08:40.559 --> 00:08:45.200
opposition on January fifteenth, making it particularly bright and visible
134
00:08:45.240 --> 00:08:48.919
all night long. Moving into February, Venus will steal the
135
00:08:48.919 --> 00:08:51.279
show on the nineteenth, when it reaches its brightest point
136
00:08:51.320 --> 00:08:54.120
of the year. Through a telescope, you'll be able to
137
00:08:54.159 --> 00:08:57.919
watch Venus transform from half lit to just thirteen percent
138
00:08:58.000 --> 00:09:02.240
lit between January and February, a fascinating demonstration of planetary
139
00:09:02.240 --> 00:09:05.679
phases visible from Earth. One of the year's most unique
140
00:09:05.720 --> 00:09:08.840
events occurs on March twenty ninth, when parts of North
141
00:09:08.840 --> 00:09:12.960
America will experience what's being called the Devil's Horns solar eclipse.
142
00:09:13.720 --> 00:09:17.759
This partial eclipse will be particularly striking at sunrise, especially
143
00:09:17.759 --> 00:09:21.159
for viewers in Atlantic Canada, Quebec and Maine, where two
144
00:09:21.159 --> 00:09:24.440
separate solar horns will appear to rise from the eastern horizon.
145
00:09:24.879 --> 00:09:28.240
The spring and summer bring us several excellent meteor showers,
146
00:09:29.200 --> 00:09:32.240
the Lerid's peak on April twenty first and twenty two
147
00:09:32.440 --> 00:09:36.639
under favorable dark skies, followed by the Etta Aquarids in
148
00:09:36.720 --> 00:09:40.399
early May. July twentieth offers a beautiful sight when a
149
00:09:40.399 --> 00:09:44.240
crescent moon visits the Plaietes star cluster, and August twelfth
150
00:09:44.279 --> 00:09:47.279
brings us a rare conjunction of Venus and Jupiter, the
151
00:09:47.320 --> 00:09:49.639
two brightest planets will appear to nearly touch in the
152
00:09:49.639 --> 00:09:54.600
pre dawn sky. The autumn season doesn't disappoint either. Saturn
153
00:09:54.639 --> 00:09:58.480
reaches opposition on September twenty first, though its famous rings
154
00:09:58.519 --> 00:10:00.759
will be harder to spot than usual as they'll be
155
00:10:00.919 --> 00:10:04.399
edge on to Earth. November fifth will feature the most
156
00:10:04.399 --> 00:10:08.879
impressive super moon since twenty nineteen, appearing notably larger and
157
00:10:08.960 --> 00:10:13.679
brighter than usual, especially at moonrise. The year rounds out
158
00:10:13.679 --> 00:10:18.120
with several meteor showers under dark skies, including the Drakenids
159
00:10:18.120 --> 00:10:22.279
in October and the Layanids in mid November. While the
160
00:10:22.360 --> 00:10:25.480
Leonids won't produce their famous storm this year that's not
161
00:10:25.559 --> 00:10:28.919
due until twenty thirty two, observers can still expect about
162
00:10:28.919 --> 00:10:33.279
fifteen metiars per hour during peak activity. Remember, while many
163
00:10:33.320 --> 00:10:35.960
of these events are visible to the naked eye, having
164
00:10:36.000 --> 00:10:38.679
a pair of binoculars or a small telescope will greatly
165
00:10:38.759 --> 00:10:42.279
enhance your viewing experience. And always try to find a
166
00:10:42.399 --> 00:10:45.559
dark location away from city lights for the best views
167
00:10:45.600 --> 00:10:50.799
of meteor showers. Finally, today, in a fascinating development for
168
00:10:50.840 --> 00:10:54.320
planetary defense, scientists have discovered a new way to track
169
00:10:54.360 --> 00:10:59.559
potentially dangerous comets by studying meteor showers. This innovative approach,
170
00:10:59.799 --> 00:11:02.519
to developed by a team led by Samantha Hemeilgarn at
171
00:11:02.519 --> 00:11:07.320
Northern Arizona University, could provide crucial early warnings about comets
172
00:11:07.519 --> 00:11:10.840
that might pose a threat to Earth. While comets have
173
00:11:10.960 --> 00:11:17.240
long captured humanity's imagination and sparked scientific curiosity, their unpredictable nature,
174
00:11:17.759 --> 00:11:21.039
especially those with long period orbits exceeding two hundred years,
175
00:11:21.559 --> 00:11:25.759
has been a persistent challenge for astronomers. These icy wanderers
176
00:11:25.799 --> 00:11:29.360
of the Solar System could theoretically approach Earth undetected until
177
00:11:29.399 --> 00:11:32.320
it's too late to respond, though the probability of such
178
00:11:32.320 --> 00:11:36.600
an event remains extremely low. The new detection method focuses
179
00:11:36.639 --> 00:11:39.639
on analyzing meteor shower data to trace the paths of
180
00:11:39.679 --> 00:11:43.200
parent comets. When Earth passes through the debris trail left
181
00:11:43.200 --> 00:11:47.120
behind by a comet, we experience these spectacular meteor showers.
182
00:11:47.480 --> 00:11:51.679
By studying seventeen different meteor showers associated with long period comets,
183
00:11:52.120 --> 00:11:55.080
researchers have developed a model that can calculate where these
184
00:11:55.120 --> 00:11:58.639
parent comets should be in space. What makes this approach
185
00:11:58.679 --> 00:12:04.080
particularly valuable is its accuracy in predicting comet locations, including
186
00:12:04.120 --> 00:12:08.279
their direction and speed of travel. Rather than scanning the
187
00:12:08.440 --> 00:12:12.879
entire sky hoping to spot a potentially hazardous comet, astronomers
188
00:12:12.919 --> 00:12:16.000
can now focus their search on specific areas where these
189
00:12:16.080 --> 00:12:19.720
objects are most likely to be found. The implications for
190
00:12:19.799 --> 00:12:23.960
planetary defense are significant. Early detection of any comet on
191
00:12:23.960 --> 00:12:26.960
a collision course with Earth would provide valuable time to
192
00:12:27.000 --> 00:12:31.679
develop and implement response strategies. While there's currently no known
193
00:12:31.720 --> 00:12:35.440
threat from any comet, this research represents an important step
194
00:12:35.440 --> 00:12:38.919
forward in our planetary defense capabilities. Think of it as
195
00:12:39.039 --> 00:12:43.840
using nature's own warning system, meteor showers serve as celestial breadcrumbs,
196
00:12:44.200 --> 00:12:46.600
leading us back to their source and helping us better
197
00:12:46.679 --> 00:12:51.000
understand and prepare for any potential future impacts. While the
198
00:12:51.039 --> 00:12:53.679
next major impact event might be millions of years away,
199
00:12:54.200 --> 00:12:58.120
this new detection method adds another crucial tool to humanity's
200
00:12:58.159 --> 00:13:04.080
planetary defense arsenal. And that wraps up another fascinating episode
