1
00:00:00.200 --> 00:00:03.279
Welcome to Astronomy Daily, your daily dose of space and

2
00:00:03.319 --> 00:00:07.240
astronomy news. Today, we're going to explore some big developments

3
00:00:07.320 --> 00:00:11.199
in space exploration and research. We'll be diving into SpaceX's

4
00:00:11.279 --> 00:00:14.359
latest lunar mission that's carrying both a private lander and

5
00:00:14.400 --> 00:00:16.600
a NASA orbiter to hunt for water on the Moon.

6
00:00:17.120 --> 00:00:20.440
We'll also look at Australia's historic preparations for their first

7
00:00:20.559 --> 00:00:24.679
orbital launch attempt, and discover how NASA technologies are revolutionizing

8
00:00:24.760 --> 00:00:28.239
life here on Earth. Plus, we'll explore some fascinating new

9
00:00:28.280 --> 00:00:32.000
findings about mysterious dwarf galaxies, check in on NASA's Lucy

10
00:00:32.039 --> 00:00:35.759
spacecraft as it approaches its next asteroid target, and uncover

11
00:00:35.840 --> 00:00:38.479
new insights into some of the most magnetic objects in

12
00:00:38.520 --> 00:00:42.479
our universe, magnetars. Let's get started with today's space news.

13
00:00:44.039 --> 00:00:47.640
In a spectacular sunset launch from NASA's Kennedy Space Center,

14
00:00:48.159 --> 00:00:53.119
SpaceX's Falcon nine rocket successfully carried two lunar bound spacecraft

15
00:00:53.159 --> 00:00:57.479
into space. The primary payload, the Athena lunar lander built

16
00:00:57.479 --> 00:01:00.520
by Intuitive Machines, is now on its way to explore

17
00:01:00.560 --> 00:01:03.560
the Moon's South Pole region in search of water ice deposits.

18
00:01:04.599 --> 00:01:08.159
This marks intuitive machines second mission to the Moon following

19
00:01:08.200 --> 00:01:12.439
their historic first landing earlier this month. Athena carries ten

20
00:01:12.560 --> 00:01:16.439
NASA science instruments, with its main package being Prime one,

21
00:01:16.760 --> 00:01:19.560
which includes a drill called Trident that can reach three

22
00:01:19.560 --> 00:01:23.200
feet below the lunar surface and a mass spectrometer to

23
00:01:23.280 --> 00:01:27.040
analyze the collected samples for water and other compounds. But

24
00:01:27.159 --> 00:01:30.920
Athena isn't traveling alone. The mission also includes an innovative

25
00:01:30.920 --> 00:01:34.200
hopper robot named Grace that will explore nearby craters through

26
00:01:34.239 --> 00:01:37.400
a series of controlled jumps, and a small rover called

27
00:01:37.480 --> 00:01:41.560
Map that will test the Moon's first cellular network. These

28
00:01:41.599 --> 00:01:44.200
tools will work together to study areas that have remained

29
00:01:44.280 --> 00:01:49.200
largely unexplored, including permanently shadowed craters where scientists believe significant

30
00:01:49.200 --> 00:01:53.120
deposits of water ice may exist. Sharing the ride is

31
00:01:53.239 --> 00:01:58.000
NASA's Lunar Trailblazer orbiter, which will map water ice deposits

32
00:01:58.000 --> 00:02:03.319
from lunar orbit, complementing Athena's ground based observations. This coordinated

33
00:02:03.319 --> 00:02:06.879
approach will give scientists an unprecedented view of lunar water

34
00:02:06.959 --> 00:02:11.560
resources critical for NASA's Artemis program and future human settlements

35
00:02:11.560 --> 00:02:15.800
on the Moon. The mission represents a significant step forward

36
00:02:16.159 --> 00:02:20.319
in commercial NASA partnerships, with intuitive machines leading the way

37
00:02:20.479 --> 00:02:24.680
in delivering scientific payloads to the lunar surface. If successful,

38
00:02:24.840 --> 00:02:28.080
Athena will touch down in the Monsmuton region, where it

39
00:02:28.120 --> 00:02:32.039
will operate for about ten Earth days, gathering crucial data

40
00:02:32.159 --> 00:02:35.960
about potential resources that could support future lunar missions and

41
00:02:36.039 --> 00:02:40.719
potentially even sustain human presence on the Moon. Next up

42
00:02:40.879 --> 00:02:44.759
one for our listeners. Down Under, Australia is about to

43
00:02:44.800 --> 00:02:49.360
mark a historic milestone in its space exploration journey. Gilmour Space,

44
00:02:49.560 --> 00:02:53.280
an Australian company that's been developing rocket technology since twenty fifteen,

45
00:02:53.680 --> 00:02:56.759
has announced its first orbital launch attempts scheduled from March

46
00:02:56.800 --> 00:03:00.039
fifteenth from the Bowen Orbital Spaceport in northern Queensland, and

47
00:03:01.080 --> 00:03:04.800
their rocket, named Airis, stands an impressive eighty two feet

48
00:03:04.800 --> 00:03:08.960
tall and represents years of Australian innovation and engineering. This

49
00:03:09.120 --> 00:03:12.280
three stage hybrid propulsion rocket is designed to carry payloads

50
00:03:12.319 --> 00:03:14.919
of up to four hundred and seventy four pounds to

51
00:03:15.000 --> 00:03:17.840
a Sun synchronous orbit three hundred and ten miles above

52
00:03:17.840 --> 00:03:22.240
Earth's surface. After securing the necessary approvals from Australia's Civil

53
00:03:22.240 --> 00:03:25.639
Aviation Safety Authority late last year. The company is now

54
00:03:25.680 --> 00:03:29.840
ready to attempt this groundbreaking launch. CEO Adam Gilmore has

55
00:03:29.879 --> 00:03:33.400
been careful to manage expectations, noting that first launches are

56
00:03:33.439 --> 00:03:38.240
notoriously challenging. Even SpaceX needed four attempts before achieving its

57
00:03:38.280 --> 00:03:42.039
first successful orbital launch. The team emphasizes that whether they

58
00:03:42.080 --> 00:03:45.879
make it off the pad, reach maximum aerodynamic pressure, or

59
00:03:45.919 --> 00:03:49.599
achieve orbit, every second of flight will provide valuable data

60
00:03:49.639 --> 00:03:53.479
to improve future launches. With more than two hundred employees

61
00:03:53.639 --> 00:03:57.960
and backing from various private investors and superannuation funds, Gilmore

62
00:03:57.960 --> 00:04:00.919
Space has grown from a small startup to a significant

63
00:04:00.919 --> 00:04:04.680
player in Australia's emerging space sector. The company isn't just

64
00:04:04.759 --> 00:04:08.400
focused on rockets. They're also developing satellite platforms with the

65
00:04:08.560 --> 00:04:12.639
ultimate goal of making space access more affordable. While the

66
00:04:12.639 --> 00:04:16.839
team remains optimistic, they acknowledge that various factors, including weather

67
00:04:16.879 --> 00:04:21.639
conditions and technical issues, could lead to delays. Safety remains

68
00:04:21.639 --> 00:04:24.120
their top priority, and they've made it clear they'll only

69
00:04:24.160 --> 00:04:28.600
proceed with the launch when all conditions are optimal. If successful,

70
00:04:29.079 --> 00:04:32.079
this mission will mark the first time an Australian designed

71
00:04:32.120 --> 00:04:35.800
and built rocket reaches orbit from Australian soil, opening a

72
00:04:35.839 --> 00:04:39.720
new chapter in the country's space exploration history. And may

73
00:04:39.759 --> 00:04:43.519
we be reporting that Australia has a happy Gilmore shortly, sorry,

74
00:04:43.639 --> 00:04:47.240
I couldn't resist. Let's take a look now at some

75
00:04:47.279 --> 00:04:51.040
of the great work NASA's been doing. NASA's latest spinoff

76
00:04:51.040 --> 00:04:54.879
publication has revealed some remarkable ways that space technology is

77
00:04:55.000 --> 00:04:58.759
revolutionizing life here on Earth. For nearly twenty five years

78
00:04:58.839 --> 00:05:02.439
of supporting astronauts in low Earth orbit, NASA has developed

79
00:05:02.439 --> 00:05:06.439
technologies that are now finding incredible applications in our daily lives.

80
00:05:07.160 --> 00:05:10.480
One of the most fascinating developments involves a platform that

81
00:05:10.519 --> 00:05:15.439
allows commercial industries to conduct space station experiments. Scientists have

82
00:05:15.560 --> 00:05:20.120
successfully grown higher quality human heart tissue, knee cartilage, and

83
00:05:20.160 --> 00:05:23.720
pharmaceutical crystals that can be used to develop new medical

84
00:05:23.720 --> 00:05:27.279
treatments right here on Earth. The innovation doesn't stop at

85
00:05:27.319 --> 00:05:31.680
medical breakthroughs. Remember those challenges of watering plants and zero gravity.

86
00:05:32.319 --> 00:05:36.480
The solution NASA developed has evolved into electrostatic sprayer technology

87
00:05:36.920 --> 00:05:41.079
now being used in sanitation, agriculture and food safety. And

88
00:05:41.120 --> 00:05:44.600
those specialized treadmills designed to keep astronauts fit in space.

89
00:05:45.360 --> 00:05:49.040
They've been adapted into anti gravity treadmills that are helping

90
00:05:49.040 --> 00:05:54.319
people with various conditions exercise more effectively. Even the nutritional

91
00:05:54.319 --> 00:05:58.319
supplements originally created to keep astronauts healthy during long space

92
00:05:58.360 --> 00:06:02.360
missions are now available for vers everyday use. But perhaps

93
00:06:02.439 --> 00:06:06.720
most exciting are the developments in construction technology. Companies are

94
00:06:06.839 --> 00:06:10.600
using NASA's three D printing techniques initially designed for building

95
00:06:10.680 --> 00:06:14.000
structures on the Moon, to print large buildings here on Earth.

96
00:06:14.839 --> 00:06:18.879
There's even research into growing buildings from fungus, a concept

97
00:06:18.920 --> 00:06:21.920
first explored for lunar construction that's now being adapted for

98
00:06:22.000 --> 00:06:25.879
Earth based housing. Quality control systems on assembly lines are

99
00:06:25.920 --> 00:06:29.399
getting smarter thanks to artificial intelligence originally developed to help

100
00:06:29.480 --> 00:06:34.240
rovers navigate Mars. And in the energy sector, NASA's expertise

101
00:06:34.240 --> 00:06:37.040
in liquid hydrogen rocket fuel is helping pave the way

102
00:06:37.079 --> 00:06:41.240
for hydrogen based energy solutions. With over forty NASA originated

103
00:06:41.279 --> 00:06:44.879
technologies now in commercial use and more in development, these

104
00:06:44.920 --> 00:06:48.839
space age innovations are quietly transforming industries and improving lives

105
00:06:48.839 --> 00:06:53.720
across our planet. Astronomers have recently made a fascinating discovery

106
00:06:53.759 --> 00:06:57.759
about the universe's smallest and faintest galaxies known as ultra

107
00:06:57.800 --> 00:07:02.720
diffuse galaxies or UDG. While studying thirty of these mysterious

108
00:07:02.759 --> 00:07:06.720
cosmic entities in the hydrogalaxy cluster, located more than one

109
00:07:06.759 --> 00:07:10.199
hundred sixty million light years from Earth, researchers found something

110
00:07:10.240 --> 00:07:14.000
completely unexpected about how these galaxies move. About half of

111
00:07:14.040 --> 00:07:18.120
the udgs they observed showed peculiar rotational patterns in their stars,

112
00:07:18.680 --> 00:07:21.600
movements that simply don't align with our current theories about

113
00:07:21.639 --> 00:07:26.160
how these faint galaxies form and evolve. This discovery is

114
00:07:26.240 --> 00:07:29.680
particularly significant because these galaxies have only been known to

115
00:07:29.759 --> 00:07:33.680
science since twenty fifteen, and they've been puzzling astronomers ever

116
00:07:33.720 --> 00:07:37.199
since with their unusually elongated shapes and ultra faint nature.

117
00:07:38.240 --> 00:07:41.519
The research team made these observations using the Meuse Integral

118
00:07:41.519 --> 00:07:45.439
Field Spectrograph on the very large telescope in Chile. One

119
00:07:45.560 --> 00:07:50.199
UDG in particular, designated as UDG thirty two, proved especially interesting.

120
00:07:50.680 --> 00:07:52.759
This dwarf galaxy was found at the end of a

121
00:07:52.759 --> 00:07:55.759
gas filament connected to a much larger spiral galaxy called

122
00:07:55.879 --> 00:07:59.879
ENNGC three thousand, three hundred fourteen A. What makes the

123
00:08:00.120 --> 00:08:03.399
finding so intriguing is that UDG thirty two's location doesn't

124
00:08:03.399 --> 00:08:07.079
appear to be mere coincidence. The stars in UDG thirty

125
00:08:07.079 --> 00:08:10.000
two are younger than those in other udgs in the cluster,

126
00:08:10.439 --> 00:08:14.040
yet surprisingly they contain more heavy elements or metals in

127
00:08:14.120 --> 00:08:18.639
astronomical terms. This suggests these stars formed from gas and

128
00:08:18.720 --> 00:08:22.120
dust that was originally part of the larger neighboring galaxy,

129
00:08:22.560 --> 00:08:26.079
supporting the theory that some udgs might form when gas

130
00:08:26.120 --> 00:08:31.160
is pulled away from larger galaxies through gravitational interactions. These

131
00:08:31.199 --> 00:08:34.399
findings are more than just interesting space facts. They're helping

132
00:08:34.480 --> 00:08:37.639
us piece together the complex puzzle of how galaxies form

133
00:08:37.799 --> 00:08:41.720
and evolve. The research team's results have effectively doubled our

134
00:08:41.759 --> 00:08:45.840
knowledge of these mysterious galaxies, providing the first comprehensive view

135
00:08:45.919 --> 00:08:49.120
of how these faint systems exist within a still forming

136
00:08:49.159 --> 00:08:52.440
galaxy cluster. It's a reminder that even in our modern

137
00:08:52.480 --> 00:08:56.159
age of astronomy, the universe still has plenty of surprises

138
00:08:56.200 --> 00:09:01.039
in store for us. Lucy NASA's ambition Just Asteroid exploring

139
00:09:01.080 --> 00:09:04.440
spacecraft has just reached an exciting milestone in its mission

140
00:09:04.480 --> 00:09:08.360
by capturing its first images of asteroid Donald Johansson, currently

141
00:09:08.440 --> 00:09:10.600
appearing as just a tiny point of light forty five

142
00:09:10.639 --> 00:09:13.879
million miles away. This two mile wide space rock will

143
00:09:13.879 --> 00:09:17.279
be Lucy's next close encounter, scheduled for an April twentieth

144
00:09:17.279 --> 00:09:19.840
flyby at a distance of just five hundred and ninety

145
00:09:19.840 --> 00:09:24.639
six miles. This upcoming visit follows Lucy's fascinating encounter last

146
00:09:24.679 --> 00:09:29.639
November with asteroid Dinkinesh and its companion moon Salam, which

147
00:09:29.679 --> 00:09:33.039
turned out to be quite the surprising duo. Salam revealed

148
00:09:33.080 --> 00:09:37.080
itself to be what scientists call a contact binary, essentially

149
00:09:37.120 --> 00:09:40.279
two separate objects touching each other, held together by their

150
00:09:40.360 --> 00:09:44.639
mutual gravitational pull. The origin of this unusual pairing remains

151
00:09:44.639 --> 00:09:48.320
a mystery, though researchers suspect Salam might have formed from

152
00:09:48.320 --> 00:09:51.519
material ejected from Dinkinesh due to the effects of solar

153
00:09:51.559 --> 00:09:56.080
heating over millions of years. While Donald Johanson currently appears

154
00:09:56.120 --> 00:09:58.919
as nothing more than a distant speck, Lucy won't get

155
00:09:58.919 --> 00:10:01.320
a detailed look at the end asteroid's features until the

156
00:10:01.399 --> 00:10:04.679
day of the close approach, But this encounter is just

157
00:10:04.879 --> 00:10:08.879
one stop on Lucy's packed itinerary. In twenty twenty seven,

158
00:10:09.080 --> 00:10:13.039
the spacecraft will reach its first Trojan asteroid Eurybites, which

159
00:10:13.080 --> 00:10:16.240
sits in a vast swarm of asteroids sharing Jupiter's orbit.

160
00:10:16.759 --> 00:10:19.759
After visiting several more trojans, Lucy will swing back by

161
00:10:19.799 --> 00:10:23.000
Earth in twenty thirty for a gravitational boost before heading

162
00:10:23.039 --> 00:10:27.440
to explore even more of these ancient Solar System remnants. Interestingly,

163
00:10:27.840 --> 00:10:30.879
the asteroid Donald Johansson's name has a direct connection to

164
00:10:30.960 --> 00:10:35.759
Lucy's own. It honors Donald Johansson, the paleoanthropologist who discovered

165
00:10:35.759 --> 00:10:38.759
the famous three point two million year old human ancestor

166
00:10:38.840 --> 00:10:43.240
fossil nicknamed Lucy. Just as that ancient skeleton helps us

167
00:10:43.279 --> 00:10:47.000
understand human evolution, the asteroids Lucy is studying are like

168
00:10:47.080 --> 00:10:50.720
fossils from our Solar System's birth, offering crucial clues about

169
00:10:50.720 --> 00:10:54.639
how our cosmic neighborhood came to be. To wrap things

170
00:10:54.720 --> 00:10:58.639
up today, in a fascinating new study published in Nature, Astronomy,

171
00:10:58.960 --> 00:11:02.000
scientists have finally begun to unravel one of astronomy's most

172
00:11:02.000 --> 00:11:06.799
perplexing mysteries, how magnetars generate their incredibly powerful magnetic fields.

173
00:11:07.279 --> 00:11:10.679
These extraordinary neutron stars have magnetic fields up to a

174
00:11:10.759 --> 00:11:14.480
thousand times stronger than typical neutron stars. Which are already

175
00:11:14.519 --> 00:11:18.080
among the most magnetic objects we know of. The breakthrough

176
00:11:18.120 --> 00:11:22.600
came from studying what scientists call low field magnetars. These

177
00:11:22.679 --> 00:11:26.240
cosmic oddities present an interesting puzzle because while their baseline

178
00:11:26.279 --> 00:11:30.039
magnetic fields are relatively weak, they somehow manage to produce

179
00:11:30.120 --> 00:11:32.919
intense bursts of X rays and gamma rays that should

180
00:11:33.000 --> 00:11:38.519
require much stronger magnetic fields. Through detailed computer simulations, researchers

181
00:11:38.519 --> 00:11:41.679
have identified a likely culprit a process known as the

182
00:11:41.720 --> 00:11:45.519
tailor Sprut dynamo. This dynamo effect occurs because of the

183
00:11:45.559 --> 00:11:49.840
way these stars rotate. Unlike a solid object spinning uniformly,

184
00:11:50.240 --> 00:11:53.600
different parts of these stars rotate at slightly different speeds.

185
00:11:54.159 --> 00:11:58.360
This differential rotation, particularly strong in their cores, creates the

186
00:11:58.399 --> 00:12:03.240
conditions needed to amplify magnetic fields to extraordinary levels. The

187
00:12:03.320 --> 00:12:06.519
process appears to be kicked off during the violent supernova

188
00:12:06.559 --> 00:12:10.639
that creates the magnetar, when angular momentum is transferred into

189
00:12:10.639 --> 00:12:14.960
the core of the dying star. For low field magnetar specifically,

190
00:12:15.399 --> 00:12:19.039
this mechanism explains how they can temporarily boost their magnetic

191
00:12:19.039 --> 00:12:23.080
field strength to produce those powerful radiation bursts we observe.

192
00:12:23.639 --> 00:12:27.360
It's a different story from traditional magnetors, which likely generate

193
00:12:27.440 --> 00:12:32.600
their consistently strong fields through other means. This discovery not

194
00:12:32.639 --> 00:12:36.080
only helps us understand these extreme objects better, but also

195
00:12:36.159 --> 00:12:40.159
provides crucial insights into the complex physics at play in

196
00:12:40.240 --> 00:12:45.879
some of the universe's most extreme environments. And that's all
