the latest news in the world of space and astronomy.

3
00:00:05.679 --> 00:00:07.000
Him Anna your host for today.

4
00:00:07.480 --> 00:00:10.240
We've got some exciting stories lined up for you, from

5
00:00:10.320 --> 00:00:13.199
NASA's Artemis three mission, to the latest updates on the

6
00:00:13.240 --> 00:00:16.519
BEPY Columbo spacecraft and more. First, we'll dive into the

7
00:00:16.559 --> 00:00:19.199
latest maneuver by the BEPI Columbo mission as it prepares

8
00:00:19.239 --> 00:00:22.719
for its fourth flyby of Mercury. We'll also explore China's

9
00:00:22.760 --> 00:00:27.440
impressive twelfth successful sea based satellite launch, a significant milestone

10
00:00:27.440 --> 00:00:30.600
in space exploration. Later, we'll talk about how the Artemis

11
00:00:30.640 --> 00:00:33.759
three mission will leverage cutting edge four G technology designed

12
00:00:33.759 --> 00:00:38.079
by Nokia to revolutionize lunar communication. Finally, we'll unravel the

13
00:00:38.119 --> 00:00:41.920
mystery behind the enigmatic lunar swirls, shedding light on new

14
00:00:41.960 --> 00:00:45.399
scientific findings about these fascinating features on the Moon's surface.

15
00:00:45.880 --> 00:00:48.600
So stay tuned for some incredible space news and insights.

16
00:00:49.159 --> 00:00:52.479
First up today, the BEPI Columbo mission, a joint effort

17
00:00:52.479 --> 00:00:56.439
by the European Space Agency ESA and the japan Aerospace

18
00:00:56.520 --> 00:01:01.280
Exploration Agency JACKSA, is gearing up for its fourth Mercury flyby.

19
00:01:01.799 --> 00:01:04.120
This is not just another flyby, but a pivotal moment

20
00:01:04.159 --> 00:01:07.159
in the mission's journey. Scheduled for twenty three forty eight

21
00:01:07.239 --> 00:01:11.319
CESST twenty one forty eight UTC on September fourth, BEPI

22
00:01:11.359 --> 00:01:14.079
Colombo will pass just one hundred and sixty five kilometers

23
00:01:14.120 --> 00:01:18.079
above Mercury surface, getting closer than ever before. Why is

24
00:01:18.120 --> 00:01:21.840
this fly by so crucial, Well, it serves a dual purpose. First,

25
00:01:21.920 --> 00:01:25.480
it will help adjust the spacecraft's speed and trajectory, essential

26
00:01:25.519 --> 00:01:29.799
for eventually settling into orbit around Mercury. Second, it offers

27
00:01:29.840 --> 00:01:33.719
a valuable opportunity for scientists to gather preliminary data and

28
00:01:33.920 --> 00:01:37.640
fine tune the operations of the onboard instruments before the

29
00:01:37.680 --> 00:01:42.079
main mission begins. Initially launched in October twenty eighteen, BEPI

30
00:01:42.159 --> 00:01:45.799
Columbo utilizes a series of nine planetary flybys to aid

31
00:01:45.840 --> 00:01:49.680
its journey, one around Earth, two around Venus, and six

32
00:01:49.719 --> 00:01:53.879
around Mercury. The mission's complexity stems from Mercury's close proximity

33
00:01:53.879 --> 00:01:57.079
to the Sun, which demands intricate maneuvers to counter the

34
00:01:57.120 --> 00:02:02.120
Sun's powerful gravitational pull and the spacecraft's own high velocity. Interestingly,

35
00:02:02.159 --> 00:02:05.840
the upcoming flyby wasn't solely routine. Engineers had to overcome

36
00:02:05.840 --> 00:02:08.520
a challenge that emerged back in April twenty twenty four

37
00:02:08.960 --> 00:02:13.360
when BEPI Colombo's Mercury Transfer Module MTM encountered an issue

38
00:02:13.360 --> 00:02:18.439
with its electric thrusters. These thrusters, essential for the spacecraft's journey,

39
00:02:18.759 --> 00:02:21.960
have been operating below the required thrust due to unexpected

40
00:02:21.960 --> 00:02:25.560
electric currents affecting the power distribution from the solar arrays.

41
00:02:26.000 --> 00:02:30.560
After months of grueling investigations, a workaround was devised. ESA's

42
00:02:30.599 --> 00:02:33.919
flight dynamics team created a new trajectory, ensuring the spacecraft

43
00:02:33.919 --> 00:02:37.639
stays on mission despite reduced thrust. This shows the resilience

44
00:02:37.680 --> 00:02:41.960
and ingenuity of the mission team, emphasizing that space exploration

45
00:02:42.159 --> 00:02:45.800
is as much about overcoming unexpected roadblocks as it is

46
00:02:45.800 --> 00:02:49.400
about discovery. The fourth flyby, set to occur soon, is

47
00:02:49.439 --> 00:02:52.199
expected to bring the spacecraft within just one hundred and

48
00:02:52.280 --> 00:02:56.319
sixty five kilometers of Mercury's surface, about thirty five kilometers

49
00:02:56.360 --> 00:03:00.000
closer than originally planned. This closer approach will further reduce

50
00:03:00.120 --> 00:03:02.719
the propulsion needed for the next two Mercury flybys in

51
00:03:02.759 --> 00:03:06.479
December twenty twenty four and January twenty twenty five, which

52
00:03:06.520 --> 00:03:10.280
are crucial for aligning bepy Colombo's orbit with Mercury. What's

53
00:03:10.319 --> 00:03:13.840
exciting is that although the mtm's primary thrusters are underperforming,

54
00:03:14.439 --> 00:03:18.240
the mission scientific objectives remain unaffected. Ten of the sixteen

55
00:03:18.280 --> 00:03:21.800
scientific instruments on board will be operational during this flyby.

56
00:03:22.280 --> 00:03:26.240
These instruments will collect data on magnetic fields, plasma, and particles,

57
00:03:26.719 --> 00:03:29.240
offering a preview of the detailed science to come once

58
00:03:29.280 --> 00:03:34.159
BEPY Columbo settles into orbit around Mercury. Johannesbenkoff, BEPY Columbo's

59
00:03:34.199 --> 00:03:38.080
project scientist, couldn't contain his excitement. He pointed out that

60
00:03:38.159 --> 00:03:40.960
this fly by allows us to explore parts of Mercury's

61
00:03:41.039 --> 00:03:44.400
environment that wouldn't be accessible once the spacecraft is in orbit.

62
00:03:44.840 --> 00:03:47.120
This is a chance to gather unique data and ensure

63
00:03:47.159 --> 00:03:50.879
a smooth transition when the main mission begins. Moreover, BEPY

64
00:03:50.919 --> 00:03:55.560
Columbo's trio of monitoring cameras mcams will capture images of Mercury.

65
00:03:56.039 --> 00:03:59.080
While these cameras were designed to monitor the spacecraft's equipment,

66
00:03:59.520 --> 00:04:02.240
they also provide black and white snapshots of the planet

67
00:04:02.639 --> 00:04:06.479
as the spacecraft zooms past Mercury. MCAM two and MCAM

68
00:04:06.560 --> 00:04:09.400
three will start capturing well lit images two minutes after

69
00:04:09.439 --> 00:04:13.360
the closest approach, giving us unprecedented views of Mercury's terrain.

70
00:04:13.840 --> 00:04:16.279
There's an extra bit of excitement surrounding this fly by,

71
00:04:16.360 --> 00:04:18.959
as it marks the first time Bepy Colombo will pass

72
00:04:19.000 --> 00:04:22.600
over Mercury's poles. This maneuver is essential for adjusting the

73
00:04:22.639 --> 00:04:27.120
spacecraft's trajectory to match Mercury's inclined orbit relative to Earth.

74
00:04:27.639 --> 00:04:30.319
Scientists are particularly eager to get a glimpse of Mercury's

75
00:04:30.319 --> 00:04:33.519
south pole through the captured images. All of these thrilling

76
00:04:33.560 --> 00:04:36.800
developments make Bepy Columbo's fourth fly by a cornerstone in

77
00:04:36.839 --> 00:04:41.079
its journey. With new data, images and a fine tuned trajectory,

78
00:04:41.439 --> 00:04:43.800
the mission is not just on track, but poised to

79
00:04:43.879 --> 00:04:46.439
deepen our understanding of Mercury and its place in our

80
00:04:46.439 --> 00:04:49.600
Solar system. Expect the first images to be released on

81
00:04:49.639 --> 00:04:52.800
September fifth, and the initial scientific results to follow on

82
00:04:52.839 --> 00:04:56.120
September thirteenth. Stay tuned as we bring you more updates

83
00:04:56.199 --> 00:04:59.120
on this incredible mission, pushing the boundaries of what we

84
00:04:59.199 --> 00:05:02.519
know about our closes planetary neighbor. Next up in today's

85
00:05:02.560 --> 00:05:06.639
story list, Galactic Energy, a private rocket manufacturer based in

86
00:05:06.720 --> 00:05:09.680
Beijing has achieved its third sea based launch of the

87
00:05:09.720 --> 00:05:13.560
Series one carrier rocket, marking China's twelfth successful sea based

88
00:05:13.600 --> 00:05:17.920
satellite launch overall. This is a significant milestone for Galactic Energy,

89
00:05:18.319 --> 00:05:21.079
cementing its position as a leading private entity in the

90
00:05:21.160 --> 00:05:25.279
Chinese space industry. On Thursday afternoon, the Series one rocket

91
00:05:25.279 --> 00:05:28.639
blasted off from a mobile launch platform, which was essentially

92
00:05:28.720 --> 00:05:31.879
a modified deck barge positioned in the Yellow Sea off

93
00:05:31.920 --> 00:05:35.199
the eastern province of Shandong. The launch was a success,

94
00:05:35.519 --> 00:05:38.639
and the rocket deployed six satellites into a sun synchronous

95
00:05:38.720 --> 00:05:42.439
orbit approximately five hundred and thirty five kilometers above the Earth.

96
00:05:42.920 --> 00:05:46.199
The newly deployed satellites come from multiple operators and serve

97
00:05:46.279 --> 00:05:50.319
various functions. They are set to collect crucial meteorological data,

98
00:05:50.720 --> 00:05:54.600
demonstrate advanced optical remote sensing technologies, and gather hyper spectral

99
00:05:54.639 --> 00:05:58.560
remote sensing data. These capabilities are expected to provide valuable

100
00:05:58.560 --> 00:06:03.399
information for both scientific research and practical applications such as

101
00:06:03.399 --> 00:06:08.199
weather forecasting and environmental monitoring. So far, Galactic Energy has

102
00:06:08.199 --> 00:06:12.639
conducted fifteen orbital launches with the Series one model, outpacing

103
00:06:12.680 --> 00:06:16.680
other private competitors in China. These missions have successfully placed

104
00:06:16.680 --> 00:06:20.480
a total of fifty four commercial satellites into orbit, showcasing

105
00:06:20.519 --> 00:06:24.240
the reliability and effectiveness of their technology. The Series one

106
00:06:24.319 --> 00:06:27.399
rocket itself stands about twenty meters tall with a diameter

107
00:06:27.519 --> 00:06:30.720
of one point four meters, and it primarily uses solid propellant.

108
00:06:31.199 --> 00:06:33.879
With a lift off weight of thirty three metric tons,

109
00:06:34.040 --> 00:06:36.720
the rocket is capable of sending a three hundred kilogram

110
00:06:36.759 --> 00:06:39.959
satellite or several satellites with a combined weight of three

111
00:06:40.000 --> 00:06:45.120
hundred kilograms into a five hundred kilometer Sun synchronous orbit. Alternatively,

112
00:06:45.199 --> 00:06:47.160
it can deliver payloads of up to three hundred and

113
00:06:47.199 --> 00:06:49.959
fifty kilograms into a low Earth orbit at an altitude

114
00:06:50.000 --> 00:06:53.920
of two hundred kilometers. This successful launch not only highlights

115
00:06:53.920 --> 00:06:58.079
the capabilities of galactic energy, but also underscores China's growing

116
00:06:58.120 --> 00:07:02.399
prowess in space exploration and satellite deployment. The use of

117
00:07:02.519 --> 00:07:07.160
sea based launches offers unique advantages, including increased launch flexibility

118
00:07:07.160 --> 00:07:11.000
and reduced risk to populated areas. Now let's get an

119
00:07:11.079 --> 00:07:14.560
Artemis update. NASA's upcoming Artemis three mission is set to

120
00:07:14.600 --> 00:07:17.360
break new ground not just by landing astronauts on the

121
00:07:17.399 --> 00:07:21.360
Moon again, but by equipping them with cutting edge communications technology.

122
00:07:21.879 --> 00:07:24.199
The space suits these astronauts will wear won't just be

123
00:07:24.240 --> 00:07:27.800
your regular space attire. They'll come with four G connectivity

124
00:07:28.040 --> 00:07:32.279
designed by none other than Nokia. Imagine this lunar explorer

125
00:07:32.279 --> 00:07:35.639
is broadcasting high definition video or transmitting large volumes of

126
00:07:35.680 --> 00:07:38.439
scientific data back to Earth in real time. It's a

127
00:07:38.600 --> 00:07:41.959
huge leap forward from the traditional UHF radio communications that

128
00:07:42.000 --> 00:07:46.439
passed missions relied on. Nokia's innovation essentially miniaturizes a mobile

129
00:07:46.439 --> 00:07:48.639
network tower into a box that can fit onto a

130
00:07:48.720 --> 00:07:52.639
lunar lander. This compressed base station will allow the astronauts

131
00:07:52.720 --> 00:07:55.600
to stay connected up to two kilometers away from the lander,

132
00:07:55.959 --> 00:07:58.959
a considerable range when you think about it. On Earth,

133
00:07:59.040 --> 00:08:02.399
a network of based towers dotted landscapes to keep us connected,

134
00:08:02.839 --> 00:08:05.480
but on the Moon we only need this compact system,

135
00:08:05.600 --> 00:08:10.519
demonstrating how scalable and adaptable our technology has become now.

136
00:08:10.560 --> 00:08:13.839
The Aximu space suits, crafted by Axiom Space won't have

137
00:08:13.879 --> 00:08:17.959
a touchscreen interface like the smartphones we're all accustomed to. Instead,

138
00:08:18.000 --> 00:08:21.360
the suits will integrate components of a smartphone customized for

139
00:08:21.399 --> 00:08:25.240
the space environment. What they'll gain from this integration is remarkable,

140
00:08:25.519 --> 00:08:28.800
including the ability to stream high definition video or send

141
00:08:28.839 --> 00:08:32.080
substantial scientific data back to the base station, which will

142
00:08:32.080 --> 00:08:33.120
then relay it to Earth.

143
00:08:33.559 --> 00:08:35.320
Traditionally, UHF radio.

144
00:08:35.080 --> 00:08:37.600
Has been the go to technology for astronauts during their

145
00:08:37.679 --> 00:08:41.120
lunar missions. While UHF has served well, it pales in

146
00:08:41.120 --> 00:08:44.080
comparison to the higher bandwidth and faster speeds offered by

147
00:08:44.120 --> 00:08:46.840
four G. Nokia has been working on this technology for

148
00:08:46.879 --> 00:08:50.000
space application since receiving a fourteen point one million dollars

149
00:08:50.120 --> 00:08:53.080
NASA grant back in twenty twenty. The company envisions of

150
00:08:53.120 --> 00:08:56.200
future where four G connectivity will benefit not just Artemis

151
00:08:56.240 --> 00:09:01.039
three astronauts, but potentially all future lunar missions. In fact,

152
00:09:01.080 --> 00:09:04.000
the first test of this lunar four G network will

153
00:09:04.000 --> 00:09:07.159
occur later this year with Intuitive Machines IM two mission.

154
00:09:07.720 --> 00:09:11.120
This mission will carry the base station, while two other payloads,

155
00:09:11.240 --> 00:09:15.279
the map rover and the Micronovadrone, will have four G receivers.

156
00:09:15.879 --> 00:09:19.759
Beyond the Artemis three mission, Nokia s's potential applications for

157
00:09:19.799 --> 00:09:23.240
this technology in various lunar devices. Think of a lunar

158
00:09:23.279 --> 00:09:26.879
terrain vehicle equipped with four G connectivity, or even smaller

159
00:09:26.919 --> 00:09:31.600
science experiments and sensors linking through this network. Throughout twenty

160
00:09:31.600 --> 00:09:34.279
twenty four and into twenty twenty five, the four G

161
00:09:34.399 --> 00:09:37.840
equipped suits will go through rigorous testing, everything from vacuum

162
00:09:37.879 --> 00:09:41.000
chambers to simulations in the indoor pool at NASA's Johnson

163
00:09:41.080 --> 00:09:44.159
Space Center. These tests aim to ensure that both the

164
00:09:44.200 --> 00:09:47.679
suits and their components can withstand the extreme conditions they'll

165
00:09:47.720 --> 00:09:52.080
face during life on the Moon. This technological leap doesn't

166
00:09:52.120 --> 00:09:55.240
just make communication easier, it opens the door for more

167
00:09:55.279 --> 00:09:59.360
advanced scientific exploration and data collection. It's an exciting time

168
00:09:59.399 --> 00:10:02.759
for SpaceX exploration as we blend the advancements made in

169
00:10:02.799 --> 00:10:06.600
consumer technology with the rigors of space travel. The Artemis

170
00:10:06.679 --> 00:10:09.759
three mission, with its four G connectivity, is certainly one

171
00:10:09.759 --> 00:10:12.559
to watch as we prepare for humanity's next giant leap

172
00:10:12.639 --> 00:10:16.879
on the lunar surface. Let's explore a truly fascinating topic,

173
00:10:17.240 --> 00:10:19.720
the mysterious light colored swirls on the Moon's surface.

174
00:10:20.360 --> 00:10:21.320
Visible through even the.

175
00:10:21.240 --> 00:10:25.360
Most basic backyard telescopes, These lunar swirls have long puzzled scientists.

176
00:10:25.840 --> 00:10:29.240
Some say these swirls resemble the brushstrokes in an abstract painting,

177
00:10:30.080 --> 00:10:34.279
but they are far from mere artistic flourishes. NASA's images

178
00:10:34.360 --> 00:10:37.759
show that These intricate patterns can extend for hundreds of miles.

179
00:10:38.200 --> 00:10:42.200
So what's behind these captivating formations. Recent studies suggest that

180
00:10:42.279 --> 00:10:45.799
lunar swirls are the result of magnetized rocks. These rocks

181
00:10:45.840 --> 00:10:48.639
create a magnetic field strong enough to deflect solar wind

182
00:10:48.639 --> 00:10:53.480
particles which bombard the Moon continuously. While nearby areas darken

183
00:10:53.600 --> 00:10:56.840
over time due to chemical reactions caused by these solar winds,

184
00:10:57.320 --> 00:11:00.440
the swirls maintain their lighter appearance because they are protected

185
00:11:00.480 --> 00:11:03.799
by their magnetic fields. This brings us to a crucial question,

186
00:11:04.279 --> 00:11:07.799
how did the rocks in these swirls become magnetized? After all,

187
00:11:07.799 --> 00:11:10.720
the Moon no longer has a global magnetic field. Recent

188
00:11:10.799 --> 00:11:13.879
modeling and spacecraft data have started to unravel this mystery.

189
00:11:14.279 --> 00:11:17.639
One popular theory is that these magnetic anomalies were caused

190
00:11:17.639 --> 00:11:21.840
by impacts, or possibly by subterranean lava with high titanium

191
00:11:21.879 --> 00:11:25.759
content cooling down in the presence of an ancient magnetic field.

192
00:11:26.639 --> 00:11:30.960
Assistant Professor Michael J. Krutchinsky from Washington University believes that

193
00:11:31.039 --> 00:11:35.039
localized magma could be the real culprit. His recent experiments,

194
00:11:35.200 --> 00:11:38.840
co designed with pH d graduate Yuan Yuan Liang, tested

195
00:11:38.879 --> 00:11:42.879
whether lunar light conditions could magnetize materials like ilmanite, a

196
00:11:42.919 --> 00:11:46.360
mineral abundant on the Moon. They concluded that high surface

197
00:11:46.440 --> 00:11:50.000
area to volume ratio in ilmanite grains could indeed create

198
00:11:50.039 --> 00:11:51.639
the necessary magnetic fields.

199
00:11:52.279 --> 00:11:54.279
These theories have significant implications.

200
00:11:54.879 --> 00:11:58.720
Understanding the origin of lunar swirls could help scientists piece

201
00:11:58.759 --> 00:12:02.720
together the historical magnetic environment of the Moon, revealing more

202
00:12:02.759 --> 00:12:06.559
about its geological history and even the broader surface effects

203
00:12:06.600 --> 00:12:08.519
experienced by other planets and moons.

204
00:12:09.039 --> 00:12:10.399
Looking ahead, NASA.

205
00:12:10.120 --> 00:12:12.000
Intends to send a rover to one of the most

206
00:12:12.039 --> 00:12:15.279
famous lunar swirls, Reiner Gamma, in twenty twenty five, as

207
00:12:15.320 --> 00:12:18.320
part of the Lunar Vertex mission. This mission aims to

208
00:12:18.360 --> 00:12:21.720
gather more data and possibly provide direct evidence of the

209
00:12:21.759 --> 00:12:26.440
processes behind these enigmatic patterns. Thus, while the mystery of

210
00:12:26.519 --> 00:12:29.879
lunar swirls has yet to be completely solved, ongoing research

211
00:12:29.960 --> 00:12:33.919
and upcoming missions are set to offer invaluable insights. For now,

212
00:12:34.120 --> 00:12:37.279
the study of these swirls continues to excite the scientific community,

213
00:12:37.759 --> 00:12:41.440
bridging the gap between remote observations and hands on lunar exploration.
