00:00:00.000 --> 00:00:02.960
Avery: Welcome to Astronomy Daily, the podcast that

1
00:00:02.960 --> 00:00:05.360
brings you the universe one story at a time.

2
00:00:05.520 --> 00:00:06.480
I'm Avery.

3
00:00:06.640 --> 00:00:08.880
Anna: And I'm Anna. It's great to be with you.

4
00:00:09.280 --> 00:00:11.280
Today we're covering everything from

5
00:00:11.280 --> 00:00:13.920
ambitious plans for lunar colonization to

6
00:00:13.920 --> 00:00:16.360
fascinating new discoveries about visitors

7
00:00:16.360 --> 00:00:17.760
from beyond our solar system.

8
00:00:18.240 --> 00:00:20.280
Avery: That's right. We'll be talking about a

9
00:00:20.280 --> 00:00:23.000
nuclear powered future on the moon, a sci

10
00:00:23.000 --> 00:00:25.320
fi concept for artificial gravity that's

11
00:00:25.320 --> 00:00:27.920
getting closer to reality, and a record

12
00:00:28.000 --> 00:00:30.400
breaking satellite launch. We've also got

13
00:00:30.400 --> 00:00:33.060
news of a major setb for one nation space

14
00:00:33.060 --> 00:00:35.820
program and a wobbly interstellar

15
00:00:35.820 --> 00:00:36.300
comet.

16
00:00:36.700 --> 00:00:39.260
Anna: So let's get right to it. Our first story

17
00:00:39.260 --> 00:00:41.500
takes us to the moon, where Russia has

18
00:00:41.500 --> 00:00:44.300
announced some truly monumental plans.

19
00:00:44.620 --> 00:00:46.700
Avery: You can say that again, Avery.

20
00:00:46.700 --> 00:00:48.900
Anna: This isn't just about setting up a temporary

21
00:00:48.900 --> 00:00:51.660
outpost. Russia's space agency has

22
00:00:51.660 --> 00:00:54.300
stated its intention to build a full fledged

23
00:00:54.380 --> 00:00:57.020
nuclear power plant on the lunar surface

24
00:00:57.100 --> 00:00:58.860
within the next decade or so.

25
00:00:59.310 --> 00:01:02.230
Avery: A nuclear power plant on the moon? That's a

26
00:01:02.230 --> 00:01:04.310
huge undertaking and they're not doing it

27
00:01:04.310 --> 00:01:04.990
alone, right?

28
00:01:05.310 --> 00:01:08.070
Anna: Exactly. This is part of a joint effort

29
00:01:08.070 --> 00:01:10.710
with China. The goal is to have the plant

30
00:01:10.710 --> 00:01:13.630
constructed and operational by 2036.

31
00:01:13.950 --> 00:01:16.510
The purpose is to provide a consistent and

32
00:01:16.510 --> 00:01:18.910
powerful energy source for a planned joint

33
00:01:18.910 --> 00:01:20.830
Russian Chinese research station.

34
00:01:21.310 --> 00:01:24.270
Avery: That makes sense. Solar power is great, but

35
00:01:24.270 --> 00:01:26.830
a, uh, lunar night lasts for about 14 Earth

36
00:01:26.830 --> 00:01:29.150
days. If you want a permanently functioning

37
00:01:29.150 --> 00:01:31.210
scientific station, you need a power power

38
00:01:31.210 --> 00:01:33.050
source that doesn't depend on sunlight.

39
00:01:33.290 --> 00:01:36.250
Anna: Right. This really signals a shift in

40
00:01:36.250 --> 00:01:38.890
lunar exploration from temporary visits

41
00:01:39.050 --> 00:01:41.810
to establishing a long term sustainable

42
00:01:41.810 --> 00:01:44.770
human presence. It's a foundational step for

43
00:01:44.770 --> 00:01:47.570
what could become a true lunar settlement one

44
00:01:47.570 --> 00:01:47.850
day.

45
00:01:48.090 --> 00:01:49.130
Avery: It's fascinating.

46
00:01:49.370 --> 00:01:51.490
And speaking of ambitious Russian plans for

47
00:01:51.490 --> 00:01:53.930
the future of space travel, our next story

48
00:01:53.930 --> 00:01:56.130
sounds like it was pulled directly from a

49
00:01:56.130 --> 00:01:57.120
science fiction movie.

50
00:01:57.670 --> 00:01:59.910
Anna: Sounds intriguing. The details please.

51
00:02:00.390 --> 00:02:03.150
Avery: The state owned Energia rocket company has

52
00:02:03.150 --> 00:02:05.590
just secured a patent for a new spacecraft

53
00:02:05.590 --> 00:02:07.670
design. And its main feature is something

54
00:02:07.670 --> 00:02:10.150
astronauts have dreamed of for decades.

55
00:02:10.470 --> 00:02:11.910
Artificial gravity.

56
00:02:12.310 --> 00:02:14.710
Anna: This is a critical piece of the puzzle for

57
00:02:14.710 --> 00:02:17.510
long duration space missions. We know that

58
00:02:17.510 --> 00:02:20.270
extended time in zero G has serious

59
00:02:20.270 --> 00:02:21.990
negative effects on the human body.

60
00:02:22.390 --> 00:02:25.190
Avery: Mm mhm. Serious effects. Things like muscle

61
00:02:25.190 --> 00:02:27.670
atrophy and significant bone density loss.

62
00:02:27.830 --> 00:02:30.770
It's one of the big hurdles for say, a manned

63
00:02:30.770 --> 00:02:31.650
mission to Mars.

64
00:02:32.130 --> 00:02:35.010
Anna: So how does this new design work? The concept

65
00:02:35.010 --> 00:02:37.690
of a rotating system to create centrifugal

66
00:02:37.690 --> 00:02:40.090
force isn't new, but what are the specifics

67
00:02:40.090 --> 00:02:40.370
here?

68
00:02:40.930 --> 00:02:43.890
Avery: Well, the patent describes a rotating system

69
00:02:43.970 --> 00:02:46.730
designed to generate a gravitational force of

70
00:02:46.730 --> 00:02:49.570
about 0.5g. So half

71
00:02:49.570 --> 00:02:52.530
of Earth's gravity while Not a, uh, full one

72
00:02:52.530 --> 00:02:55.170
G. It's believed that even this level could

73
00:02:55.170 --> 00:02:57.330
profoundly mitigate the health problems

74
00:02:57.330 --> 00:02:58.290
astronauts face.

75
00:02:58.620 --> 00:03:01.460
Anna: Halfigy would make a world of difference. It

76
00:03:01.460 --> 00:03:04.060
means crews could arrive at Mars or return to

77
00:03:04.060 --> 00:03:06.700
Earth in much better physical condition. This

78
00:03:06.700 --> 00:03:08.980
could be a genuine game changer for the

79
00:03:08.980 --> 00:03:10.540
future of human spaceflight.

80
00:03:10.780 --> 00:03:11.660
Avery: Absolutely.

81
00:03:11.980 --> 00:03:14.300
From future tech to current accomplishments,

82
00:03:14.540 --> 00:03:16.740
let's shift our focus to a remarkable

83
00:03:16.740 --> 00:03:19.460
satellite that's now in orbit. Anna, uh, tell

84
00:03:19.460 --> 00:03:20.940
us about Bluebird 6.

85
00:03:21.260 --> 00:03:23.900
Anna: This is a story about connectivity.

86
00:03:24.490 --> 00:03:26.730
An Indian rocket recently launched the

87
00:03:26.730 --> 00:03:29.570
Bluebird 6 satellite, and it's a

88
00:03:29.570 --> 00:03:32.330
record breaker. It was built by a Texas based

89
00:03:32.410 --> 00:03:35.370
company, AST Space Mobile. And

90
00:03:35.370 --> 00:03:38.010
its mission is to provide broadband Internet

91
00:03:38.010 --> 00:03:40.970
service directly to standard off the shelf

92
00:03:40.970 --> 00:03:43.290
smartphones on the ground, directly to

93
00:03:43.290 --> 00:03:43.690
phones.

94
00:03:43.690 --> 00:03:46.090
Avery: So no special equipment needed. That's the

95
00:03:46.090 --> 00:03:48.650
key. But what makes it a record breaker?

96
00:03:48.970 --> 00:03:51.970
Anna: Its size. To talk to a small device like

97
00:03:51.970 --> 00:03:54.650
a cell phone from orbit, you need a very,

98
00:03:54.970 --> 00:03:57.750
very large. Bluebird 6

99
00:03:57.750 --> 00:04:00.030
features a, uh, communication array of nearly

100
00:04:00.030 --> 00:04:01.910
2,400 square feet.

101
00:04:02.310 --> 00:04:04.990
Avery: Wow, 2,400 square feet. That's

102
00:04:04.990 --> 00:04:05.430
massive.

103
00:04:05.750 --> 00:04:08.190
Anna: It is. In fact, it's the largest

104
00:04:08.190 --> 00:04:10.630
communication array ever deployed in low

105
00:04:10.630 --> 00:04:13.310
Earth orbit. The potential impact here is

106
00:04:13.310 --> 00:04:15.830
enormous, offering a way to connect the

107
00:04:15.830 --> 00:04:18.190
unconnected in the most remote parts of the

108
00:04:18.190 --> 00:04:18.550
globe.

109
00:04:18.870 --> 00:04:20.630
Avery: That's an incredible piece of engineering

110
00:04:20.630 --> 00:04:23.310
with a very noble goal. But as we know,

111
00:04:23.310 --> 00:04:25.710
getting these complex machines into orbit is

112
00:04:25.710 --> 00:04:26.630
the hardest part.

113
00:04:27.240 --> 00:04:28.840
Which brings us to our next story.

114
00:04:29.080 --> 00:04:31.440
Unfortunately, not all recent launches have

115
00:04:31.440 --> 00:04:32.120
been successful.

116
00:04:32.360 --> 00:04:35.320
Anna: That's right, Avery. Japan's ambitions for

117
00:04:35.320 --> 00:04:37.800
an independent satellite navigation system

118
00:04:37.960 --> 00:04:40.680
suffered a significant blow after the second

119
00:04:40.760 --> 00:04:43.520
major failure of its flagship H3

120
00:04:43.520 --> 00:04:44.120
rocket.

121
00:04:44.440 --> 00:04:46.400
Avery: This is a tough one for the Japanese space

122
00:04:46.400 --> 00:04:48.440
program. The rocket was supposed to deliver

123
00:04:48.440 --> 00:04:51.320
the Michibiki 5 satellite into orbit, but it

124
00:04:51.320 --> 00:04:52.360
failed during its flight.

125
00:04:52.760 --> 00:04:55.440
Anna: And this satellite was a crucial component of

126
00:04:55.440 --> 00:04:58.120
their Quasi Zenith Satellite System, or

127
00:04:58.120 --> 00:04:59.240
qzss.

128
00:04:59.980 --> 00:05:02.880
Avery: Mhm. The QZSS is designed to augment

129
00:05:02.880 --> 00:05:05.480
GPS signals, providing much more accurate and

130
00:05:05.480 --> 00:05:07.840
reliable positioning for Japan and the rest

131
00:05:07.840 --> 00:05:10.640
of East Asia. This failure represents a major

132
00:05:10.640 --> 00:05:12.560
delay to the expansion and improvement of

133
00:05:12.560 --> 00:05:13.080
that system.

134
00:05:13.480 --> 00:05:15.640
Anna: It's a stark reminder that even for

135
00:05:15.640 --> 00:05:18.400
established spacefaring nations, rocket

136
00:05:18.400 --> 00:05:20.880
science is incredibly challenging. There's

137
00:05:20.880 --> 00:05:23.520
just no room for error. We certainly hope

138
00:05:23.520 --> 00:05:25.800
they can identify and fix the issue for

139
00:05:25.800 --> 00:05:26.640
future flights.

140
00:05:26.960 --> 00:05:29.160
Avery: Indeed, it's a reminder of the high stakes in

141
00:05:29.160 --> 00:05:30.080
space exploration.

142
00:05:30.400 --> 00:05:31.360
Anna: It truly is.

143
00:05:31.680 --> 00:05:34.360
And for our final story, we're venturing far

144
00:05:34.360 --> 00:05:36.800
from Earth to look at one from another solar

145
00:05:36.800 --> 00:05:38.800
system that's been paying us a bit of a

146
00:05:38.800 --> 00:05:39.040
visit.

147
00:05:39.440 --> 00:05:41.440
Avery: Astronomers have been studying the

148
00:05:41.440 --> 00:05:43.600
interstellar comet 3I

149
00:05:44.160 --> 00:05:46.920
ATLAS, which has begun leaving our solar

150
00:05:46.920 --> 00:05:49.160
system. And they've observed some very

151
00:05:49.160 --> 00:05:51.970
unusual behavior. First, it has

152
00:05:51.970 --> 00:05:54.890
a rare sun facing anti tail.

153
00:05:55.210 --> 00:05:58.170
Anna: An anti tail. So a tail of

154
00:05:58.170 --> 00:06:01.090
dust and gas pointing towards the sun instead

155
00:06:01.090 --> 00:06:01.930
of away from it.

156
00:06:02.090 --> 00:06:03.920
Avery: It's an optical illusion caused by our, uh,

157
00:06:03.970 --> 00:06:06.290
viewing angle of the comet's dust trail. But

158
00:06:06.290 --> 00:06:08.330
what's truly remarkable is what's happening

159
00:06:08.330 --> 00:06:10.930
within that tail. As the comet approached the

160
00:06:10.930 --> 00:06:13.370
sun, scientists observe jets of outgassing

161
00:06:13.370 --> 00:06:15.130
material that appear to be wobbling.

162
00:06:15.530 --> 00:06:17.690
Anna: Wobbling jets. That's new.

163
00:06:18.200 --> 00:06:20.240
Avery: Completely. This is the first time such an

164
00:06:20.240 --> 00:06:22.120
outgassing pattern has ever been observed

165
00:06:22.120 --> 00:06:24.800
from an interstellar comet. The jets were

166
00:06:24.800 --> 00:06:27.640
seen to wobble on a very specific cycle every

167
00:06:27.640 --> 00:06:29.560
7 hours and 45 minutes.

168
00:06:29.880 --> 00:06:32.480
Anna: And that tells us something fundamental about

169
00:06:32.480 --> 00:06:34.199
the comet itself, doesn't it?

170
00:06:34.280 --> 00:06:36.840
Avery: It does. This wobble implies a rotational

171
00:06:36.840 --> 00:06:39.600
period for the comet's solid nucleus. Based

172
00:06:39.600 --> 00:06:41.520
on the data, scientists have calculated that

173
00:06:41.520 --> 00:06:43.800
the nucleus is spinning on its axis once

174
00:06:43.800 --> 00:06:45.320
every 15 and a half hours.

175
00:06:45.920 --> 00:06:48.800
Anna: That is so cool. To be able to determine

176
00:06:48.800 --> 00:06:51.040
the length of a day on an object that came

177
00:06:51.040 --> 00:06:53.960
from an entirely different solar system just

178
00:06:53.960 --> 00:06:56.800
by watching its jets wobble. It's an amazing

179
00:06:56.800 --> 00:06:58.480
piece of cosmic detective work.

180
00:06:58.800 --> 00:06:59.840
Avery: It certainly is.

181
00:06:59.920 --> 00:07:02.000
And that's all the time we have for today's

182
00:07:02.000 --> 00:07:04.720
