00:00:00.000 --> 00:00:02.400
Avery: Hello, and welcome to today's edition of

1
00:00:02.400 --> 00:00:05.040
Astronomy Daily, the podcast that brings you

2
00:00:05.040 --> 00:00:07.960
the universe one story at a time. I'm

3
00:00:07.960 --> 00:00:08.560
Avery.

4
00:00:08.640 --> 00:00:10.960
Anna: And I'm Anna. It's great to be with you.

5
00:00:11.200 --> 00:00:13.080
Today. We're covering some of the most

6
00:00:13.080 --> 00:00:16.080
exciting and slightly worrying news from the

7
00:00:16.080 --> 00:00:17.440
world of space exploration.

8
00:00:17.920 --> 00:00:20.320
Avery: Absolutely. We're going to be talking about a

9
00:00:20.320 --> 00:00:23.120
communications breakdown at Mars, a

10
00:00:23.120 --> 00:00:25.720
2 million kilometer tail trailing our own

11
00:00:25.720 --> 00:00:28.080
planet, and a brand new mission control

12
00:00:28.080 --> 00:00:29.520
center for future rovers.

13
00:00:30.150 --> 00:00:32.110
Anna: Plus, we'll dive into what the James Webb

14
00:00:32.110 --> 00:00:34.750
Telescope might have found on an exoplanet, a

15
00:00:34.750 --> 00:00:37.390
new dual mode drone from China, and a

16
00:00:37.390 --> 00:00:39.910
rocket fairing nicknamed the Hungry Hippo.

17
00:00:40.150 --> 00:00:43.030
Avery: It's a busy lineup, so let's get right into

18
00:00:43.030 --> 00:00:43.350
it.

19
00:00:43.510 --> 00:00:45.120
Anna, why don't you start us off with the

20
00:00:45.120 --> 00:00:46.360
news from the Red Planet?

21
00:00:46.520 --> 00:00:49.320
Anna: Of course, our first story is a bit tense.

22
00:00:49.560 --> 00:00:52.400
NASA has temporarily. Well, we hope it's

23
00:00:52.400 --> 00:00:54.840
temporary. Lost contact with its MAVEN

24
00:00:54.840 --> 00:00:57.720
orbiter. But maven, which stands for Mars

25
00:00:57.720 --> 00:01:00.640
Atmosphere and Volatile Evolution, has been a

26
00:01:00.640 --> 00:01:02.760
workhorse at Mars since 2014.

27
00:01:03.320 --> 00:01:05.200
Avery: Right, and it's not just studying the

28
00:01:05.200 --> 00:01:07.720
atmosphere. It's a critical communications

29
00:01:07.720 --> 00:01:10.160
relay for the rovers on the surface. Like

30
00:01:10.160 --> 00:01:12.920
Curiosity. And perseverance, losing

31
00:01:12.920 --> 00:01:14.360
contact is a big deal.

32
00:01:14.760 --> 00:01:17.680
Anna: Exactly. The spacecraft went silent after

33
00:01:17.680 --> 00:01:19.800
passing behind Mars from our point of view,

34
00:01:20.040 --> 00:01:22.310
which is a standard procedure, but. But when

35
00:01:22.310 --> 00:01:24.190
it should have re emerged and checked in,

36
00:01:24.190 --> 00:01:26.470
there was nothing. The team at the Jet

37
00:01:26.470 --> 00:01:28.590
Propulsion Laboratory is now working through

38
00:01:28.590 --> 00:01:31.110
procedures to try and reestablish a signal.

39
00:01:31.350 --> 00:01:31.440
Mm,

40
00:01:31.400 --> 00:01:33.440
Avery: So what does this mean for the rovers? Are

41
00:01:33.440 --> 00:01:34.680
they on their own for now?

42
00:01:35.000 --> 00:01:37.720
Anna: Well, thankfully, NASA has redundancy.

43
00:01:37.800 --> 00:01:40.080
The Mars Reconnaissance Orbiter and the

44
00:01:40.080 --> 00:01:42.840
European Space Agency's Trace Gas Orbiter

45
00:01:42.920 --> 00:01:45.720
can also act as relays so the rovers aren't

46
00:01:45.720 --> 00:01:48.560
completely cut off. But losing MAVEN reduces

47
00:01:48.560 --> 00:01:51.080
their data downlink capacity significantly.

48
00:01:51.720 --> 00:01:53.960
Avery: That makes sense. Spacecraft issues like this

49
00:01:53.960 --> 00:01:56.600
happen, and usually the engineers find a way.

50
00:01:56.840 --> 00:01:58.880
We're certainly hoping they get MAVEN back

51
00:01:58.880 --> 00:01:59.640
online soon.

52
00:01:59.960 --> 00:02:02.520
Anna: Fingers crossed. Now, for our next story,

53
00:02:02.520 --> 00:02:05.320
let's come a little closer to home, Avery.

54
00:02:05.320 --> 00:02:07.159
This one sounds like something out of science

55
00:02:07.159 --> 00:02:07.720
fiction.

56
00:02:07.960 --> 00:02:10.800
Avery: It really does. A new NASA study

57
00:02:10.800 --> 00:02:13.680
has confirmed that Earth has a tail. Not

58
00:02:13.680 --> 00:02:16.520
a physical one, of course, but a magnetic

59
00:02:16.520 --> 00:02:19.250
one, a. A magnetotail, to be precise. That

60
00:02:19.250 --> 00:02:21.570
stretches an incredible 2 million

61
00:02:21.650 --> 00:02:23.090
kilometers into space.

62
00:02:23.730 --> 00:02:26.730
Anna: 2 million kilometers. That's more than five

63
00:02:26.730 --> 00:02:29.090
times the distance to the Moon. How is that

64
00:02:29.090 --> 00:02:29.890
even formed?

65
00:02:30.130 --> 00:02:32.130
Avery: It's created by the interaction between

66
00:02:32.130 --> 00:02:34.690
Earth's magnetic field and the solar wind,

67
00:02:34.690 --> 00:02:36.970
which is a constant stream of charged

68
00:02:36.970 --> 00:02:39.850
particles flowing from the Sun. As the Solar

69
00:02:39.850 --> 00:02:42.570
wind blows past Earth. It stretches our

70
00:02:42.570 --> 00:02:45.050
magnetic field out on the night side. Just

71
00:02:45.050 --> 00:02:46.050
like a windsock.

72
00:02:46.530 --> 00:02:49.300
Anna: Right, and this tail isn't empty, is it? it's

73
00:02:49.300 --> 00:02:50.380
filled with plasma.

74
00:02:50.700 --> 00:02:53.660
Avery: Exactly. It's a plasma kale. And

75
00:02:53.660 --> 00:02:56.140
understanding its structure and dynamics is

76
00:02:56.140 --> 00:02:58.500
crucial for predicting space weather, which

77
00:02:58.500 --> 00:03:00.780
can affect our satellites and power grids.

78
00:03:01.020 --> 00:03:03.940
It's a stunning reminder of the complex and

79
00:03:03.940 --> 00:03:06.300
visible structures that dominate our corner

80
00:03:06.300 --> 00:03:07.180
of the cosmos.

81
00:03:07.660 --> 00:03:08.860
Anna: That's fascinating.

82
00:03:09.180 --> 00:03:11.980
From invisible tales to very visible new

83
00:03:11.980 --> 00:03:14.700
buildings, Our next story takes us to NASA's

84
00:03:14.700 --> 00:03:16.900
Jet Propulsion Laboratory. They've just

85
00:03:16.900 --> 00:03:19.760
opened Rover Operations center, or

86
00:03:19.760 --> 00:03:20.520
roc.

87
00:03:20.920 --> 00:03:23.720
Avery: Yeah, this is exciting. This isn't just a

88
00:03:23.720 --> 00:03:26.280
shiny new room with more computers. The

89
00:03:26.280 --> 00:03:28.920
ROC is designed to be the heart of future

90
00:03:28.920 --> 00:03:31.720
robotic missions to the Moon and m Mars. It's

91
00:03:31.720 --> 00:03:33.480
built to handle multiple missions

92
00:03:33.559 --> 00:03:34.600
simultaneously.

93
00:03:35.000 --> 00:03:37.120
Anna: And it incorporates some cutting edge

94
00:03:37.120 --> 00:03:39.880
technology, including advanced AI to help

95
00:03:39.880 --> 00:03:42.640
rover drivers plan their routes and analyze

96
00:03:42.640 --> 00:03:44.550
data more efficiently. They're also

97
00:03:44.550 --> 00:03:46.630
emphasizing partnerships with commercial

98
00:03:46.630 --> 00:03:47.270
space companies.

99
00:03:47.750 --> 00:03:50.750
Avery: That partnership piece is key. With programs

100
00:03:50.750 --> 00:03:53.150
like Artemis aiming to return humans to the

101
00:03:53.150 --> 00:03:55.710
moon and more ambitious Mars missions on the

102
00:03:55.710 --> 00:03:58.630
horizon, NASA needs a central hub that can

103
00:03:58.630 --> 00:04:01.030
coordinate between its own assets and those

104
00:04:01.030 --> 00:04:03.750
of its commercial partners. The ROC

105
00:04:03.830 --> 00:04:06.710
is that hub. It's basically mission control

106
00:04:06.870 --> 00:04:08.950
for the next generation of explorers.

107
00:04:09.590 --> 00:04:12.230
Anna: Speaking of next generation explorers, our

108
00:04:12.230 --> 00:04:14.270
next story comes from the James Webb Space

109
00:04:14.270 --> 00:04:16.410
Telescope, which is continu continuing to

110
00:04:16.410 --> 00:04:18.530
rewrite our understanding of distant worlds.

111
00:04:18.930 --> 00:04:21.850
Avery: I love a good JWST story. What has

112
00:04:21.850 --> 00:04:22.690
it spotted now?

113
00:04:23.090 --> 00:04:25.410
Anna: It's been looking at the Trappist 1 system,

114
00:04:25.650 --> 00:04:27.810
which you'll remember as a system of seven

115
00:04:27.890 --> 00:04:30.650
rocky Earth sized planets orbiting a small

116
00:04:30.650 --> 00:04:33.624
star. JWST focused on Trappist

117
00:04:33.716 --> 00:04:36.450
1 e, a planet in the habitable zone.

118
00:04:36.450 --> 00:04:38.730
And the data hints at the possibility of a

119
00:04:38.730 --> 00:04:40.290
methane rich atmosphere.

120
00:04:40.690 --> 00:04:43.690
Avery: Wow. Methane on Earth, that's often

121
00:04:43.690 --> 00:04:46.450
associated with life. But the key word here

122
00:04:46.450 --> 00:04:47.810
is hints, right?

123
00:04:48.430 --> 00:04:51.230
Anna: Precisely. The data is still ambiguous.

124
00:04:51.470 --> 00:04:53.230
Scientists are quick to point out that

125
00:04:53.230 --> 00:04:55.630
methane can also be produced by geological

126
00:04:55.630 --> 00:04:58.190
processes, not just biological ones.

127
00:04:58.430 --> 00:05:00.910
The signal is also faint and could be an

128
00:05:00.910 --> 00:05:02.910
instrument artifact or something else

129
00:05:02.910 --> 00:05:03.470
entirely.

130
00:05:04.030 --> 00:05:06.430
Avery: So it's not time to announce aliens just yet.

131
00:05:06.910 --> 00:05:09.710
Anna: Not just yet, but it is an incredibly

132
00:05:09.710 --> 00:05:12.670
tantalizing result. It shows that JWST

133
00:05:12.910 --> 00:05:14.830
is capable of detecting potential

134
00:05:14.830 --> 00:05:17.670
biosignatures on rocky exoplanets, which

135
00:05:17.670 --> 00:05:20.410
is exactly what it was designed to do. More

136
00:05:20.410 --> 00:05:22.570
observations are already planned to get a

137
00:05:22.570 --> 00:05:23.290
clearer picture.

138
00:05:23.690 --> 00:05:26.250
Avery: It's amazing to watch science unfold in real

139
00:05:26.250 --> 00:05:29.050
time. And while JWST looks out,

140
00:05:29.130 --> 00:05:31.250
other nations are looking at new ways to

141
00:05:31.250 --> 00:05:32.170
explore up close.

142
00:05:32.570 --> 00:05:35.290
Our fifth story is About a new type of Mars

143
00:05:35.290 --> 00:05:37.050
drone being developed in China.

144
00:05:37.450 --> 00:05:39.640
Anna: Mm We all remember the success of NASA's

145
00:05:39.640 --> 00:05:42.640
Ingenuity helicopter. This new concept takes

146
00:05:42.640 --> 00:05:45.200
that a step further. Chinese scientists are

147
00:05:45.200 --> 00:05:47.720
designing a drone that can both fly and roll

148
00:05:47.720 --> 00:05:48.920
on the Martian surface.

149
00:05:49.640 --> 00:05:52.280
Avery: Fly and roll. So it's a transformer?

150
00:05:52.600 --> 00:05:55.440
Anna: In a way, yes. The idea is to conserve

151
00:05:55.440 --> 00:05:58.120
energy. Flying in Mars thin atmosphere

152
00:05:58.120 --> 00:06:00.960
takes a lot of power. So the drone would roll

153
00:06:00.960 --> 00:06:03.240
on its wheels for long distance travel across

154
00:06:03.240 --> 00:06:06.160
flat terrain and only use its rotors to fly

155
00:06:06.160 --> 00:06:08.760
over obstacles or explore hard to reach areas

156
00:06:08.840 --> 00:06:10.360
like canyons or cliffs.

157
00:06:10.840 --> 00:06:13.520
Avery: That's a very clever solution. It combines

158
00:06:13.520 --> 00:06:16.000
the endurance of a rover with the agility of

159
00:06:16.000 --> 00:06:16.680
a helicopter.

160
00:06:17.310 --> 00:06:19.670
Anna: It is. And the design could even allow it to

161
00:06:19.670 --> 00:06:21.870
enter and explore Martian lava tubes or

162
00:06:21.870 --> 00:06:24.470
caves. Something no previous mission has been

163
00:06:24.470 --> 00:06:26.670
able to do. It's a concept that could

164
00:06:26.670 --> 00:06:28.670
dramatically expand our exploration

165
00:06:28.670 --> 00:06:30.430
capabilities on other worlds.

166
00:06:30.830 --> 00:06:33.430
Avery: That is a fascinating concept. It really

167
00:06:33.430 --> 00:06:35.070
shows how we're getting smarter about

168
00:06:35.070 --> 00:06:36.430
exploring other planets.

169
00:06:36.830 --> 00:06:39.070
Anna: It's certainly an exciting time in space

170
00:06:39.070 --> 00:06:39.710
innovation.

171
00:06:40.190 --> 00:06:42.430
Avery: Alright, for our final story, let's talk

172
00:06:42.430 --> 00:06:44.430
about getting to space in the first place.

173
00:06:44.750 --> 00:06:47.190
This one involves Rocket Lab and a piece of

174
00:06:47.190 --> 00:06:49.690
hardware with a fantastic nickname. The

175
00:06:49.690 --> 00:06:51.210
Hungry Hippo Fairing.

176
00:06:51.610 --> 00:06:54.090
Anna: I was waiting for this one. This is about

177
00:06:54.090 --> 00:06:56.210
their upcoming neutron rocket, which is

178
00:06:56.210 --> 00:06:59.050
designed to be fully reusable. The fairing is

179
00:06:59.050 --> 00:07:00.930
the nose cone that protects the satellite

180
00:07:00.930 --> 00:07:03.290
during launch. Typically fairings are just

181
00:07:03.290 --> 00:07:05.209
jettisoned and fall into the ocean.

182
00:07:05.610 --> 00:07:08.610
Avery: Right. Which is wasteful. SpaceX recovers

183
00:07:08.610 --> 00:07:11.490
theirs with nets on ships. But Rocket Lab has

184
00:07:11.490 --> 00:07:14.050
a totally different approach. The Neutron's

185
00:07:14.050 --> 00:07:16.380
fairing isn't jettisoned at all. It's

186
00:07:16.380 --> 00:07:18.060
integrated into the first stage of the

187
00:07:18.060 --> 00:07:18.500
rocket.

188
00:07:18.900 --> 00:07:20.580
Anna: So how does the satellite get out?

189
00:07:20.900 --> 00:07:23.380
Avery: This is the brilliant part. The fairing

190
00:07:23.380 --> 00:07:26.100
pedals open up like a, giant clamshell or a

191
00:07:26.100 --> 00:07:28.740
Hungry Hungry Hippo to release the payload.

192
00:07:28.980 --> 00:07:31.579
Then they close again before the entire first

193
00:07:31.579 --> 00:07:34.500
stage returns to Earth for a landing. Rocket

194
00:07:34.500 --> 00:07:36.700
Lab just completed successful tests of this

195
00:07:36.700 --> 00:07:37.220
mechanism.

196
00:07:37.700 --> 00:07:40.220
Anna: That's an elegant piece of engineering. It

197
00:07:40.220 --> 00:07:42.580
eliminates the entire process of fairing

198
00:07:42.580 --> 00:07:45.020
recovery at sea. It just comes back with the

199
00:07:45.020 --> 00:07:45.460
booster.

200
00:07:45.880 --> 00:07:48.280
Avery: It's a huge step towards rapid reusability,

201
00:07:48.360 --> 00:07:50.480
which is the key to lowering the cost of

202
00:07:50.480 --> 00:07:53.120
access to space. A very cool innovation to

203
00:07:53.120 --> 00:07:53.400
watch.

204
00:07:53.960 --> 00:07:56.520
Anna: And that's all the time we have for today's

205
00:07:56.520 --> 00:07:59.280
news roundup. From a silent orbiter at

206
00:07:59.280 --> 00:08:01.930
Mars to a hippo, like rocket here on Earth.

207
00:08:02.090 --> 00:08:04.490
It's been another busy time in space.

208
00:08:04.890 --> 00:08:07.810
Avery: It certainly has. Thank you all so much for

209
00:08:07.810 --> 00:08:10.530
tuning in to Astronomy Daily. You can find us

210
00:08:10.530 --> 00:08:12.770
wherever you get your podcasts, and we'd love

211
00:08:12.770 --> 00:08:15.330
it if you'd leave us a review. Join us next

212
00:08:15.330 --> 00:08:17.770
time as we take a dive into more mysteries

213
00:08:17.770 --> 00:08:18.690
from deep space.

214
00:08:19.250 --> 00:08:21.330
Anna: Until then, keep looking up.
