00:00:00.160 --> 00:00:03.120
Hello, and welcome to Astronomy Daily, your source for the

2
00:00:03.200 --> 00:00:07.960
latest and most fascinating developments in space exploration and astronomical discoveries.

3
00:00:08.480 --> 00:00:10.880
I'm your host, Anna, and I'm excited to guide you

4
00:00:10.919 --> 00:00:13.960
through today's cosmic journey. We have a stellar lineup of

5
00:00:13.960 --> 00:00:14.560
stories for you.

6
00:00:14.599 --> 00:00:14.960
Today.

7
00:00:15.359 --> 00:00:18.800
We'll be exploring NASA's Deep Space Network as it celebrates

8
00:00:18.839 --> 00:00:21.760
sixty years in Australia while breaking ground on a new

9
00:00:21.839 --> 00:00:25.480
radio antenna. Then we'll look at Saturn's rings as they

10
00:00:25.519 --> 00:00:28.719
present a rare edge on view that occurs only every.

11
00:00:28.440 --> 00:00:29.800
Fourteen to fifteen years.

12
00:00:30.679 --> 00:00:34.240
We'll also cover this week's busy launch schedule, including Amazon's

13
00:00:34.280 --> 00:00:39.200
Project Kuiper Satellites and Blue Origins first all woman crew. Plus,

14
00:00:39.359 --> 00:00:42.799
we'll examine the growing commercial demand for lunar landers beyond

15
00:00:42.880 --> 00:00:46.679
NASA and dive into a breakthrough discovery about the origin

16
00:00:46.759 --> 00:00:50.600
of black hole magnetism that solves a long standing cosmic mystery.

17
00:00:51.560 --> 00:00:54.359
So strap in as we blast off into today's exploration

18
00:00:54.399 --> 00:00:57.399
of our fascinating universe. Here we go with one for

19
00:00:57.439 --> 00:01:02.520
our Ausie listeners. NASA's Deep Space Network in Canberra, Australia

20
00:01:02.560 --> 00:01:08.159
recently celebrated a significant milestone Its sixtieth anniversary. This celebration

21
00:01:08.280 --> 00:01:11.239
came with an exciting development, as the facility broke ground

22
00:01:11.239 --> 00:01:14.159
on a new radio antenna, marking the beginning of its

23
00:01:14.159 --> 00:01:18.239
next chapter in space communications. The Canberra facility has been

24
00:01:18.239 --> 00:01:21.879
a vital part of NASA's global communications network since joining

25
00:01:21.959 --> 00:01:26.799
in nineteen sixty five, currently operating four massive radio antennas.

26
00:01:27.159 --> 00:01:29.920
The addition of this fifth dish represents a crucial expansion

27
00:01:29.959 --> 00:01:33.280
of the network's overall capacity to handle the ever increasing

28
00:01:33.319 --> 00:01:36.719
flow of data from missions across our solar system. This

29
00:01:36.760 --> 00:01:40.079
new antenna, designated Deep Space Station thirty three, will be

30
00:01:40.120 --> 00:01:43.079
a marvel of modern engineering. At one hundred and twelve

31
00:01:43.079 --> 00:01:46.879
feet wide that's about thirty four meters, this multi frequency

32
00:01:47.000 --> 00:01:51.879
beam waveguide antenna will significantly boost the network's capabilities. What

33
00:01:52.040 --> 00:01:54.840
makes this design particularly interesting is that most of its

34
00:01:54.879 --> 00:01:59.439
structure will actually be buried underground. A massive concrete pedestal

35
00:01:59.719 --> 00:02:03.400
will house cutting edge electronics and receivers in climate controlled rooms,

36
00:02:03.840 --> 00:02:08.719
providing a solid foundation for the reflector dish above. When operational,

37
00:02:09.000 --> 00:02:12.439
the dish will rotate during communications on a steel platform

38
00:02:12.960 --> 00:02:16.159
called an alidate, allowing it to track spacecraft as they

39
00:02:16.159 --> 00:02:21.479
move across the sky. This sophisticated design ensures reliable communication

40
00:02:21.599 --> 00:02:25.759
with distant spacecraft exploring the farthest reaches of our Solar system.

41
00:02:26.919 --> 00:02:32.000
Kevin Coggins, Deputy Associate Administrator of NASA's Space Communications and

42
00:02:32.080 --> 00:02:37.319
Navigation Program, highlighted the significance of this development, noting that

43
00:02:37.479 --> 00:02:41.080
as they look back on sixty years of incredible accomplishments

44
00:02:41.120 --> 00:02:44.800
at Canberra, the groundbreaking of this new antenna symbolizes the

45
00:02:44.840 --> 00:02:48.879
next sixty years of scientific discovery. The construction of such

46
00:02:48.919 --> 00:02:53.120
advanced communication technology demonstrates the Deep Space Network's commitment to

47
00:02:53.199 --> 00:02:57.560
embracing new technologies that enable exploration by an expanding fleet

48
00:02:57.599 --> 00:03:00.960
of space missions. The new Camber dish is expected to

49
00:03:01.000 --> 00:03:03.560
go online in twenty twenty nine and will be the

50
00:03:03.560 --> 00:03:07.759
final installation of six parabolic dishes constructed under NASA's Deep

51
00:03:07.759 --> 00:03:13.039
Space Network Aperture Enhancement Program. This program is specifically designed

52
00:03:13.039 --> 00:03:16.520
to support current and future spacecraft and accommodate the increasing

53
00:03:16.599 --> 00:03:20.240
volume of data they transmit back to Earth. Similar upgrades

54
00:03:20.280 --> 00:03:23.639
have already taken place at the network's Madrid facility, which

55
00:03:23.719 --> 00:03:26.360
christened a new dish in twenty twenty two, while the

56
00:03:26.360 --> 00:03:30.159
Goldstone facility in California is completing work on another antenna.

57
00:03:31.080 --> 00:03:34.439
The Deep Space Network operates through a brilliantly simple yet

58
00:03:34.439 --> 00:03:39.840
effective concept three communication facilities positioned strategically around the globe

59
00:03:40.039 --> 00:03:44.639
approximately one hundred twenty degrees apart. This careful placement ensures

60
00:03:44.639 --> 00:03:48.039
that as Earth rotates, at least one facility always has

61
00:03:48.120 --> 00:03:50.680
line of sight to any spacecraft in our Solar system,

62
00:03:51.159 --> 00:03:54.919
providing continuous coverage twenty four hours a day, regardless of

63
00:03:54.919 --> 00:03:58.680
where those spacecraft may be. The network officially began on

64
00:03:58.719 --> 00:04:02.680
December twenty fourth, nineteen sixty three, when NASA connected its

65
00:04:02.680 --> 00:04:06.960
early ground stations, including Goldstone, to the new network control

66
00:04:07.000 --> 00:04:11.599
center at the Jet Propulsion Laboratory in southern California. Madrid

67
00:04:11.680 --> 00:04:15.199
joined in nineteen sixty four, followed by Canberra in nineteen

68
00:04:15.280 --> 00:04:19.079
sixty five. Since then, these facilities have been the lifeline

69
00:04:19.079 --> 00:04:23.040
for hundreds of space missions, including historic achievements like the

70
00:04:23.040 --> 00:04:27.959
Apollo Moon landings. What makes Canberra particularly special is its

71
00:04:28.000 --> 00:04:32.560
location in the southern Hemisphere. This unique positioning grants it

72
00:04:32.600 --> 00:04:36.199
an exclusive capability. It's the only facility that can both

73
00:04:36.240 --> 00:04:39.560
send commands to and receive data from Voyager two as

74
00:04:39.560 --> 00:04:43.680
it journeys southward through interstellar Space, now almost thirteen billion

75
00:04:43.720 --> 00:04:47.720
miles from Earth. Its sister craft, Voyager one, which is

76
00:04:47.759 --> 00:04:50.839
even more distant at over fifteen billion miles away, can

77
00:04:50.879 --> 00:04:54.279
transmit data to the Madrid and Goldstone complexes, but can

78
00:04:54.319 --> 00:04:57.920
only receive commands via Canberra. The Deep Space network currently

79
00:04:57.920 --> 00:05:01.720
relies primarily on radio frequencies for co communication, but NASA

80
00:05:01.800 --> 00:05:05.480
is looking toward the future with exciting new technologies. The

81
00:05:05.519 --> 00:05:10.480
agency is experimenting with laser or optical communications, which operates

82
00:05:10.519 --> 00:05:15.079
at significantly higher frequencies than radio. This difference is crucial

83
00:05:15.079 --> 00:05:18.079
because higher frequencies allow for substantially more data to be

84
00:05:18.120 --> 00:05:22.759
transmitted over the same period. This advancement isn't just theoretical.

85
00:05:23.399 --> 00:05:26.439
NASA is actively testing it through the Deep Space Optical

86
00:05:26.439 --> 00:05:30.279
Communications Experiment aboard the Psyche mission, launched in October twenty

87
00:05:30.279 --> 00:05:34.879
twenty three. The results have been impressive, demonstrating record breaking

88
00:05:35.040 --> 00:05:39.680
high data rates over unprecedented distances, and even successfully downlinking

89
00:05:39.800 --> 00:05:44.160
ultra high definition streaming video from deep space. These new

90
00:05:44.199 --> 00:05:47.720
technologies have the potential to boost the science and exploration

91
00:05:47.800 --> 00:05:52.439
returns of missions traveling throughout the Solar System, explained Amy Smith,

92
00:05:52.680 --> 00:05:57.000
Deputy Project manager for the Deep Space network. Looking further ahead,

93
00:05:57.439 --> 00:06:01.680
researchers in vision combining laser and radio communications to create

94
00:06:01.759 --> 00:06:05.759
hybrid antennas dishes that can communicate using both radio and

95
00:06:05.839 --> 00:06:12.000
optical frequencies, simultaneously, potentially revolutionizing how we communicate with distant spacecraft.

96
00:06:12.879 --> 00:06:16.240
As our exploration of space grows more ambitious, with missions

97
00:06:16.319 --> 00:06:20.519
venturing further into the Solar System and returning increasingly complex

98
00:06:20.560 --> 00:06:24.120
scientific data, the Deep Space Network continues to evolve to

99
00:06:24.120 --> 00:06:28.199
meet these demands, ensuring that humanity maintains its connection to

100
00:06:28.240 --> 00:06:32.920
our most distant explorers. Astronomy fans, here's one for you.

101
00:06:33.439 --> 00:06:36.199
If you've looked at Saturn through a telescope lately, you

102
00:06:36.279 --> 00:06:40.040
might be wondering where those iconic rings went. The ringed

103
00:06:40.079 --> 00:06:43.720
planet is looking distinctly ringless these days, thanks to a

104
00:06:43.759 --> 00:06:48.160
fascinating astronomical alignment that happens only once every fourteen to

105
00:06:48.199 --> 00:06:52.360
fifteen years, Saturn's rings have turned edge on as seen

106
00:06:52.399 --> 00:06:55.199
from Earth, rendering them nearly invisible even.

107
00:06:55.040 --> 00:06:56.360
Through powerful telescopes.

108
00:06:56.920 --> 00:06:59.759
This phenomenon is tied to Saturn's twenty nine point five

109
00:06:59.839 --> 00:07:03.399
year orbit around the Sun. The planet's magnificent rings are

110
00:07:03.439 --> 00:07:06.759
tilted twenty seven degrees with respect to its orbital plane,

111
00:07:07.120 --> 00:07:10.120
which means that from our earthly perspective, our view of

112
00:07:10.160 --> 00:07:13.199
the rings cycles from wide open to edge on and

113
00:07:13.240 --> 00:07:16.759
back again over roughly fifteen year intervals. The rings were

114
00:07:16.839 --> 00:07:19.399
last edge on to Earth on March twenty third, and

115
00:07:19.439 --> 00:07:21.839
they'll be edge on to the Sun on May sixth.

116
00:07:22.800 --> 00:07:26.319
What makes this disappearing axodramatic is the stark contrast between

117
00:07:26.360 --> 00:07:30.399
the rings enormous width and their paper thin profile. While

118
00:07:30.439 --> 00:07:33.839
Saturn's rings span an impressive two hundred eighty two thousand

119
00:07:33.920 --> 00:07:37.360
kilometers across that's almost three quarters of the distance from

120
00:07:37.360 --> 00:07:41.199
Earth to the Moon, they're astonishingly thin, averaging just about

121
00:07:41.240 --> 00:07:44.040
one hundred meters in thickness, so when we view them

122
00:07:44.120 --> 00:07:48.399
exactly edge on, they essentially vanish from sight. Galileo was

123
00:07:48.439 --> 00:07:51.839
the first to observe Saturn's rings in sixteen ten, though

124
00:07:51.879 --> 00:07:54.399
with his primitive telescope he couldn't quite make out what

125
00:07:54.480 --> 00:07:57.879
he was seeing. His sketches show a strange, twin lobed

126
00:07:57.920 --> 00:08:01.600
world that resembled a double handled coffee cup, a testament

127
00:08:01.639 --> 00:08:05.759
to the limitations of early astronomical equipment. It wasn't until

128
00:08:05.839 --> 00:08:09.959
later that Christian Huygens correctly deduced that these handles were

129
00:08:10.000 --> 00:08:14.759
actually rings, completely detached from the planet itself. Today, we

130
00:08:14.839 --> 00:08:18.560
understand that Saturn's rings consist primarily of countless ice particles

131
00:08:18.839 --> 00:08:22.079
ranging from snowball sized to much larger, along with some

132
00:08:22.199 --> 00:08:25.240
rocky debris, and while every gas and ice giant in

133
00:08:25.279 --> 00:08:28.399
our Solar System has some form of ring system, none

134
00:08:28.480 --> 00:08:31.720
are as spectacular or as visible from Earth as Saturns.

135
00:08:32.679 --> 00:08:35.840
Perhaps the most surprising discovery about Saturn's rings in recent

136
00:08:35.919 --> 00:08:40.279
years is their relative youth. Several studies now suggest that

137
00:08:40.320 --> 00:08:43.440
the rings may be a surprisingly recent addition to the planet,

138
00:08:43.879 --> 00:08:47.000
possibly forming just ten to one hundred million years ago

139
00:08:47.320 --> 00:08:51.759
practically yesterday. In cosmic terms, this means that if dinosaurs

140
00:08:51.759 --> 00:08:55.279
had somehow developed telescopes, they might have observed a rather

141
00:08:55.480 --> 00:09:00.240
ordinary looking Saturn without its distinctive halo. Even more intriguing

142
00:09:00.759 --> 00:09:04.480
is the ring's limited future. Scientists predict that in the

143
00:09:04.480 --> 00:09:08.120
next few hundred million years, the rings will gradually dissipate

144
00:09:08.159 --> 00:09:12.360
from view as gravitational forces pull their particles, either into

145
00:09:12.399 --> 00:09:16.559
Saturn itself or fling them outward into space. We're actually

146
00:09:16.639 --> 00:09:19.519
witnessing Saturn during a special period when its rings are

147
00:09:19.559 --> 00:09:22.960
at their most magnificent, a cosmic coincidence that makes our

148
00:09:22.960 --> 00:09:27.840
era particularly fortunate for astronomical observation. So while Saturn might

149
00:09:27.879 --> 00:09:31.720
look a bit bland during this edge on phase, take heart.

150
00:09:32.200 --> 00:09:35.279
The rings are still there, and they'll gradually become visible

151
00:09:35.320 --> 00:09:38.759
again as the viewing angle changes, reaching their maximum tilt

152
00:09:38.799 --> 00:09:42.960
once more in twenty thirty two. Sometimes in astronomy, the

153
00:09:43.000 --> 00:09:47.919
most fascinating phenomena are not what appears, but what temporarily disappears.

154
00:09:49.000 --> 00:09:52.320
April offers some excellent opportunities for early risers to spot

155
00:09:52.360 --> 00:09:56.840
Saturn despite its temporarily ringless appearance. If you're hoping to

156
00:09:56.879 --> 00:09:59.919
observe this unusual site, Venus will be your best guy.

157
00:10:00.080 --> 00:10:03.879
In the dawn sky. Shining brilliantly at magnitude minus four

158
00:10:03.919 --> 00:10:07.440
point six, Venus outshine Saturn by over one hundred times,

159
00:10:07.879 --> 00:10:10.600
making it an unmistakable beacon pointing the way to the

160
00:10:10.600 --> 00:10:14.279
more subdued Saturn, which currently glows at magnitude plus one

161
00:10:14.320 --> 00:10:18.799
point two. Mercury completes this planetary dawn trio, reaching its

162
00:10:18.840 --> 00:10:22.240
greatest elongation twenty seven degrees from the Sun on April

163
00:10:22.279 --> 00:10:25.360
twenty first. Mark your calendar for the morning of April

164
00:10:25.399 --> 00:10:28.840
twenty fifth, when the waning crescent Moon joins this celestial

165
00:10:28.879 --> 00:10:32.679
gathering in the eastern sky. While the moon won't pass

166
00:10:32.720 --> 00:10:36.000
directly in front of Saturn during this particular alignment, it

167
00:10:36.039 --> 00:10:40.360
creates a beautiful photo opportunity for astrophotographers and a striking

168
00:10:40.440 --> 00:10:44.399
visual for casual observers. If you're interested in seeing a

169
00:10:44.480 --> 00:10:48.000
lunar occultation of Saturn, you'll need to wait until April

170
00:10:48.000 --> 00:10:53.679
twenty fourth, twenty thirty one. Astronomy often rewards patients for

171
00:10:53.759 --> 00:10:57.559
telescope owners. This ring plain crossing period offers a rare

172
00:10:57.639 --> 00:11:02.200
observing opportunity. With the rings essentially invisible, you can enjoy

173
00:11:02.320 --> 00:11:05.600
unobstructed views of Saturn's moons as they transit across the

174
00:11:05.639 --> 00:11:09.519
planet's disc. These transit events where moons pass in front

175
00:11:09.559 --> 00:11:12.960
of Saturn from our perspective, are commonly observed on Jupiter,

176
00:11:13.000 --> 00:11:15.320
but are only visible on Saturn during years when the

177
00:11:15.399 --> 00:11:20.480
rings are edge On Titan, Saturn's largest moon is particularly

178
00:11:20.519 --> 00:11:23.840
worth watching, as it casts a prominent shadow during its transits.

179
00:11:24.519 --> 00:11:28.000
These events occur approximately every sixteen earth days as Titan

180
00:11:28.039 --> 00:11:31.240
completes its orbit, though catching one requires being in the

181
00:11:31.320 --> 00:11:34.440
right location at the right time, As each transit lasts

182
00:11:34.480 --> 00:11:39.039
about five hours. Specialized websites like PDS, rings Node and

183
00:11:39.159 --> 00:11:43.759
IMCCEE France provide predictions for these events, or you can

184
00:11:43.840 --> 00:11:47.559
use astronomy software like Stellarium to check for upcoming transits

185
00:11:47.559 --> 00:11:52.480
before planning an observation session. As the year progresses, Saturn

186
00:11:52.559 --> 00:11:55.960
will reach quadrature west of the Sun on June twenty second,

187
00:11:56.600 --> 00:11:59.559
an excellent time to observe the planet, casting its shadow

188
00:11:59.559 --> 00:12:03.399
across what remains visible of the rings, creating a striking

189
00:12:03.519 --> 00:12:08.240
three dimensional appearance. After reaching opposition on September twenty first,

190
00:12:08.679 --> 00:12:12.440
Saturn will transition back into the evening sky. By the

191
00:12:12.559 --> 00:12:15.360
end of twenty twenty five, the rings will have tilted

192
00:12:15.399 --> 00:12:18.159
about one degree open to our line of sight, and

193
00:12:18.200 --> 00:12:21.720
they'll continue widening until they reach their maximum tilt again

194
00:12:21.840 --> 00:12:26.120
in twenty thirty two. Saturn's unique orientation affects not just

195
00:12:26.200 --> 00:12:29.759
its appearance, but also its brightness, with the current edge

196
00:12:29.840 --> 00:12:33.200
on view reducing its magnitude to plus one point two

197
00:12:33.200 --> 00:12:35.720
compared to minus zero point five to four when the

198
00:12:35.799 --> 00:12:39.600
rings are fully tilted toward Earth. Let's look at this

199
00:12:39.639 --> 00:12:42.960
week's busy launch schedule next. This week is shaping up

200
00:12:43.000 --> 00:12:46.240
to be a remarkably active period in spaceflight, with five

201
00:12:46.360 --> 00:12:50.879
major launches taking place across multiple launch providers and mission types.

202
00:12:51.360 --> 00:12:55.480
The action begins with United Launch Alliances Atlas five rocket,

203
00:12:55.799 --> 00:12:58.120
which is set to lift off on April ninth at

204
00:12:58.200 --> 00:13:02.480
seven pm Eastern Time from Space Launch Complex forty one

205
00:13:02.639 --> 00:13:06.519
at Cape Canaveral Space four station in Florida. This mission

206
00:13:06.559 --> 00:13:10.480
carries special significance as it will deploy the first operational

207
00:13:10.480 --> 00:13:15.000
batch of Amazon's Project Kuiper satellites, marking a major milestone

208
00:13:15.000 --> 00:13:18.679
for the Internet Constellation program. The Atlas five will be

209
00:13:18.720 --> 00:13:22.840
flying in its most powerful configuration, designated five hundred and

210
00:13:22.919 --> 00:13:27.360
fifty one, featuring a five meter faring five solid rocket boosters,

211
00:13:27.600 --> 00:13:31.399
and a single engine Centaur upper stage. This robust setup

212
00:13:31.440 --> 00:13:33.840
is necessary to handle what will be the heaviest payload

213
00:13:33.919 --> 00:13:37.480
ever launched by an Atlas five, twenty seven Kuiper satellites

214
00:13:37.519 --> 00:13:39.759
bound for low Earth orbit at an altitude of four

215
00:13:39.879 --> 00:13:43.679
hundred fifty kilometers. SpaceX dominates the middle portion of the

216
00:13:43.679 --> 00:13:46.919
week with a trio of Falcon nine launches. First up

217
00:13:46.960 --> 00:13:50.360
on April tenth at nine forty three pm Eastern Time

218
00:13:50.440 --> 00:13:55.159
is a Starlink mission designated Group twelve seventeen, carrying approximately

219
00:13:55.200 --> 00:13:58.960
twenty Starlink V two mini satellites. This launch will depart

220
00:13:59.000 --> 00:14:02.039
from Launch Complex thirty nine A at Kennedy Space Center,

221
00:14:02.279 --> 00:14:05.279
sending the satellites on a southeastern trajectory to an orbit

222
00:14:05.320 --> 00:14:08.559
inclined at forty three degrees. Just two days later, on

223
00:14:08.600 --> 00:14:12.159
April twelfth, SpaceX shifts operations to the West Coast for

224
00:14:12.200 --> 00:14:15.600
a national security mission. A Falcon nine will lift off

225
00:14:15.639 --> 00:14:18.960
from Vandenberg Space Force Space in California at five seventeen

226
00:14:19.000 --> 00:14:23.399
am Pacific time, carrying a classified payload designated NROL one

227
00:14:23.519 --> 00:14:27.799
hundred ninety two for the National Reconnaissance Office. While details

228
00:14:27.840 --> 00:14:31.399
remain classified, this is believed to be the ninth SpaceX

229
00:14:31.440 --> 00:14:36.200
mission deploying Starshield satellites for reconnaissance operations such as Earth

230
00:14:36.240 --> 00:14:40.480
imaging and early missile warning detection. SpaceX rounds out its

231
00:14:40.480 --> 00:14:43.399
busy schedule with another Starlink launch on April thirteenth at

232
00:14:43.519 --> 00:14:46.159
nine to fifty nine pm Eastern Time from Space Launch

233
00:14:46.159 --> 00:14:49.919
Complex forty at Cape Canaveral. This mission, Starlink Group six

234
00:14:50.159 --> 00:14:54.080
seventy three, will deliver another batch of approximately twenty V

235
00:14:54.200 --> 00:14:57.320
two Mini satellites to the same forty three degree inclined

236
00:14:57.399 --> 00:15:00.919
orbit as the earlier Starlink launch. A week concludes with

237
00:15:01.000 --> 00:15:04.200
Blue Origins New Shepherd rocket taking flight on April fourteenth

238
00:15:04.240 --> 00:15:06.840
at nine thirty a m. Eastern time from Launch Site

239
00:15:06.879 --> 00:15:11.480
one in West Texas. This suborbital mission, designated NS thirty one,

240
00:15:11.799 --> 00:15:15.080
will carry a historic all woman crew of six passengers

241
00:15:15.399 --> 00:15:20.200
Aisha bo Amanda and Guyen, Gail King, Katy Perry, Carrie

242
00:15:20.200 --> 00:15:23.840
Anne Flynn, and Lauren Sanchez. The flight will take the

243
00:15:23.919 --> 00:15:28.039
crew above the internationally recognized Carmen line at one hundred kilometers,

244
00:15:28.440 --> 00:15:31.919
allowing them to experience several minutes of weightlessness before returning

245
00:15:31.960 --> 00:15:37.159
to Earth approximately eleven minutes after launch. The lunar economy

246
00:15:37.200 --> 00:15:40.399
appears to be gaining momentum as companies involved in NASA's

247
00:15:40.399 --> 00:15:45.919
Commercial Lunar Payload Services CLPS program report increasing interest from

248
00:15:45.919 --> 00:15:50.480
customers beyond the Space Agency. While NASA funding still accounts

249
00:15:50.480 --> 00:15:53.679
for about ninety percent of mission costs, the remaining ten

250
00:15:53.720 --> 00:15:56.480
percent comes from a diverse group of clients that includes

251
00:15:56.519 --> 00:16:02.639
international space agencies, universities, private companies, and even ride share customers.

252
00:16:03.320 --> 00:16:07.120
Intuitive Machines, which successfully landed on the Moon in March

253
00:16:07.200 --> 00:16:11.200
with its second lander, is seeing tangible growth in commercial demand.

254
00:16:11.720 --> 00:16:14.879
According to Trent martin the company's senior vice president for

255
00:16:14.919 --> 00:16:18.799
space systems, the commercial market is real and it's growing.

256
00:16:19.720 --> 00:16:22.759
This shift suggests we're witnessing the early stages of a

257
00:16:22.759 --> 00:16:27.960
sustainable lunar marketplace, rather than just government subsidized missions. These

258
00:16:28.000 --> 00:16:31.200
companies are finding that data gathered during scientific missions creates

259
00:16:31.240 --> 00:16:35.960
pathways to future commercial opportunities. David Wheeler, general counsel at

260
00:16:36.000 --> 00:16:39.840
Firefly Aerospace, points out that current activities like Regulith sample

261
00:16:39.879 --> 00:16:44.600
collections serve as precursors for resource extraction and mining. Similarly,

262
00:16:44.879 --> 00:16:48.279
Ananda Martin of I Space Technologies believes the scientific data

263
00:16:48.279 --> 00:16:52.279
being collected now will support further phases of lunar development,

264
00:16:52.639 --> 00:16:56.559
such as extraction and eventually human habitation. Although a report

265
00:16:56.600 --> 00:16:59.559
released last November by the Center for Strategic and International

266
00:16:59.559 --> 00:17:03.679
Studies found no indication of a lunar gold rush, industry

267
00:17:03.720 --> 00:17:08.640
insiders maintain that commercial interest is steadily increasing. They argue

268
00:17:08.680 --> 00:17:12.359
that the economics will improve with each successful mission as

269
00:17:12.440 --> 00:17:17.000
lunar flights become more affordable and less risky. International space

270
00:17:17.000 --> 00:17:20.920
agencies are already participating in these commercial ventures, albeit at

271
00:17:20.920 --> 00:17:24.599
a smaller scale than NASA, As Trent Martin explained, they

272
00:17:24.599 --> 00:17:27.400
don't have one hundred fifty million dollars to fund a mission,

273
00:17:27.880 --> 00:17:30.279
but maybe they have ten million dollars to fund a

274
00:17:30.319 --> 00:17:32.759
small instrument that they want to fly on the lander.

275
00:17:34.200 --> 00:17:38.039
Intuitive Machines has secured multiple contracts with foreign space agencies

276
00:17:38.039 --> 00:17:41.799
to carry payloads on future lunar missions. Companies are also

277
00:17:41.839 --> 00:17:47.039
discovering unexpected business opportunities along the way. Intuitive Machines has

278
00:17:47.039 --> 00:17:51.079
found additional revenue streams by offering orbital transportation services for

279
00:17:51.160 --> 00:17:56.519
satellites and creating a lunar communications network. When rideshare customers

280
00:17:56.519 --> 00:17:59.920
on their recent mission experienced difficulties communicating with their saddle

281
00:18:00.079 --> 00:18:03.640
lights at lunar distance, they turn to Intuitive Machines for help,

282
00:18:03.799 --> 00:18:08.079
revealing a new market need. The emerging picture suggests that

283
00:18:08.160 --> 00:18:11.960
while we're not yet seeing a full fledged commercial lunar ecosystem,

284
00:18:12.440 --> 00:18:16.200
the foundation is being laid through these initial CLPS missions.

285
00:18:17.079 --> 00:18:21.079
With each successful landing, these companies are building technical capabilities,

286
00:18:21.480 --> 00:18:26.200
operational experience, and business relationships that could eventually transform lunar

287
00:18:26.240 --> 00:18:30.960
activities from primarily government funded scientific endeavors into a sustainable

288
00:18:30.960 --> 00:18:36.359
commercial enterprise. Finally, today, one of the most enduring mysteries

289
00:18:36.400 --> 00:18:40.160
in astrophysics has finally been solved, revealing the origin of

290
00:18:40.160 --> 00:18:43.920
the powerful magnetic fields that enable black holes to create

291
00:18:44.000 --> 00:18:48.839
spectacular cosmic fireworks. Scientists at the Flat Iron Institute and

292
00:18:48.880 --> 00:18:52.359
their collaborators have discovered that these magnetic fields are inherited

293
00:18:52.400 --> 00:18:55.880
directly from the dying stars that give birth to black holes.

294
00:18:56.880 --> 00:19:00.599
Black holes are known primarily for their immense gravitational pull

295
00:19:00.880 --> 00:19:05.160
that traps everything nearby. However, they can also produce intense

296
00:19:05.240 --> 00:19:09.559
jets of charged particles that generate gamma ray bursts, explosive

297
00:19:09.599 --> 00:19:12.359
events that release more energy in seconds than our Sun

298
00:19:12.440 --> 00:19:17.119
will emit across its entire lifetime. These phenomena require extremely

299
00:19:17.160 --> 00:19:20.240
strong magnetic fields, but until now, the source of this

300
00:19:20.319 --> 00:19:25.079
magnetism remained elusive. Through detailed computer simulations tracking a star's

301
00:19:25.079 --> 00:19:29.279
evolution from collapse to black hole formation, researchers identified the

302
00:19:29.279 --> 00:19:33.039
critical mechanism at work. As a massive star explodes in

303
00:19:33.079 --> 00:19:36.160
a supernova, it leaves behind a dense core called a

304
00:19:36.200 --> 00:19:40.200
proto neutron star. When this proto neutron star collapses to

305
00:19:40.240 --> 00:19:44.519
form a black hole, its magnetic field doesn't simply disappear. Instead,

306
00:19:44.559 --> 00:19:47.200
it transfers to the disc of swirling matter that forms

307
00:19:47.200 --> 00:19:50.880
around the newborn black hole. Proto neutron stars are the

308
00:19:50.920 --> 00:19:54.960
mothers of black holes, explains Orgotlieb, the study's lead author.

309
00:19:55.440 --> 00:19:58.279
What we are seeing is that as this black hole forms,

310
00:19:58.599 --> 00:20:02.480
the proto neutron stars rounding disc will essentially pin its

311
00:20:02.519 --> 00:20:06.519
magnetic lines to the black hole. This discovery resolves a

312
00:20:06.559 --> 00:20:11.920
significant theoretical paradox that had puzzled scientists. Previous theories suggested

313
00:20:11.920 --> 00:20:17.640
that magnetic fields were compressed during stellar collapse, enhancing their strength. However,

314
00:20:18.039 --> 00:20:22.079
such strong magnetism causes stars to lose their rotation, and

315
00:20:22.160 --> 00:20:25.640
without rapid rotation, a black hole can't form the accretion

316
00:20:25.759 --> 00:20:29.480
disk necessary to produce jets and gamma ray bursts. The

317
00:20:29.480 --> 00:20:33.400
team's calculations revealed a critical timing element. The black hole's

318
00:20:33.440 --> 00:20:35.960
disc forms faster than the black hole can lose its

319
00:20:35.960 --> 00:20:40.039
inherited magnetism. This sequence preserves the magnetic field lines from

320
00:20:40.079 --> 00:20:43.119
the parent neutron star, anchoring them to the black hole's

321
00:20:43.119 --> 00:20:47.839
accretion disc. The implications extend throughout astrophysics, potentially changing how

322
00:20:47.920 --> 00:20:53.480
scientists understand jet formation in various cosmic systems. As Gottlieb notes,

323
00:20:53.960 --> 00:20:56.440
this study changes the way we think about what types

324
00:20:56.480 --> 00:20:59.640
of systems can support jet formation, because if we know

325
00:20:59.720 --> 00:21:03.720
that a accretion disks imply magnetism, then in theory, all

326
00:21:03.759 --> 00:21:06.599
you need is an early disc formation to power jets.

327
00:21:07.559 --> 00:21:10.480
This breakthrough helps explain how black holes can generate the

328
00:21:10.519 --> 00:21:14.359
most luminous explosions in the universe and provides a comprehensive

329
00:21:14.400 --> 00:21:18.119
picture of these extraordinary cosmic objects from birth to maturity.

330
00:21:18.880 --> 00:21:22.559
Previous theories about black hole magnetism painted an incomplete picture.

331
00:21:23.240 --> 00:21:26.839
Scientists had long thought that as stars collapsed, their magnetic

332
00:21:26.880 --> 00:21:31.720
fields were simply compressed and intensified, but this explanation created

333
00:21:31.720 --> 00:21:36.000
a fundamental paradox that had astronomers scratching their heads for years.

334
00:21:36.680 --> 00:21:39.480
The problem was this, a strong magnetic field causes a

335
00:21:39.480 --> 00:21:43.240
star to lose its rotation, and without rapid rotation, a

336
00:21:43.279 --> 00:21:47.160
newborn black hole can't form an accretion disc, that swirling

337
00:21:47.200 --> 00:21:50.880
collection of matter that surrounds it. Without an accretion disc,

338
00:21:51.359 --> 00:21:54.559
you can't get the powerful jets that produce gamma ray bursts.

339
00:21:55.279 --> 00:21:58.079
So how could black holes have both the strong magnetic

340
00:21:58.119 --> 00:22:03.160
fields and the accretion discs needed for these spectacular cosmic phenomena.

341
00:22:04.000 --> 00:22:08.039
Gottlieb's team realized that past simulations had missed something crucial.

342
00:22:08.559 --> 00:22:13.079
They'd only considered isolated neutron stars and black holes, ignoring

343
00:22:13.119 --> 00:22:17.200
the complex interactions between them during the collapse process. The

344
00:22:17.319 --> 00:22:20.720
key insight was recognizing that neutron stars have their own

345
00:22:20.720 --> 00:22:26.119
accretion discs before they collapse. It appears to be mutually exclusive.

346
00:22:26.359 --> 00:22:29.839
Gottlieb explains, you need two things for jets to form,

347
00:22:30.200 --> 00:22:33.519
a strong magnetic field and an accretion disc. But a

348
00:22:33.559 --> 00:22:36.759
magnetic field acquired by such compression won't form an accretion disc,

349
00:22:37.079 --> 00:22:39.200
and if you reduce the magnetism to the point where

350
00:22:39.200 --> 00:22:41.599
the disc can form, then it's not strong enough to

351
00:22:41.599 --> 00:22:45.599
produce the jets. The new calculations revealed a solution to

352
00:22:45.640 --> 00:22:49.079
this puzzle. As a neutron star begins to collapse, but

353
00:22:49.160 --> 00:22:52.000
before all its magnetic field is swallowed by the forming

354
00:22:52.000 --> 00:22:56.039
black hole, the neutron star's disc is actually inherited by

355
00:22:56.079 --> 00:22:59.640
the black hole. During this process, the magnetic field lines

356
00:22:59.640 --> 00:23:03.200
become anchored in the disc, preserving the magnetism even as

357
00:23:03.240 --> 00:23:07.559
the central object transforms. It's a bit like a cosmic inheritance.

358
00:23:08.240 --> 00:23:11.960
The mother neutron star passes down its magnetic genes to

359
00:23:12.079 --> 00:23:15.759
its child black hole through the medium of the accretion disc.

360
00:23:16.359 --> 00:23:20.319
This transfer happens because the timescale for disc formation is

361
00:23:20.359 --> 00:23:24.359
shorter than the timescale for magnetic field dissipation. This discovery

362
00:23:24.400 --> 00:23:28.359
fundamentally changes our understanding of black hole formation and jet production.

363
00:23:28.920 --> 00:23:31.680
It suggests that any system where an accretion disc forms

364
00:23:31.720 --> 00:23:36.599
quickly enough could potentially support jet formation. The researchers are

365
00:23:36.599 --> 00:23:40.160
now reconsidering various types of stellar systems and their potential

366
00:23:40.240 --> 00:23:44.440
for generating these powerful cosmic phenomena. The work demonstrates the

367
00:23:44.480 --> 00:23:50.400
power of multidisciplinary collaboration and advanced computational resources. By bringing

368
00:23:50.440 --> 00:23:54.839
together experts from different fields and running more comprehensive simulations

369
00:23:54.880 --> 00:23:58.240
than ever before, the team was able to see connections

370
00:23:58.240 --> 00:24:02.839
that had previously been missed. Well. That brings us to

371
00:24:02.880 --> 00:24:06.319
the end of another fascinating episode of Astronomy Daily. From

372
00:24:06.359 --> 00:24:09.599
