00:00:00,200 --> 00:00:03,560
Speaker 1: 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
Station twenty five three inshores will be ready to support

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
