00:00:00.480 --> 00:00:03.280
Anna: Hello, space enthusiasts. I'm Anna.

1
00:00:03.360 --> 00:00:06.160
Avery: And I'm, um, Avery. Welcome to Astronomy

2
00:00:06.160 --> 00:00:08.680
Daily, your daily dose of space and

3
00:00:08.680 --> 00:00:10.520
astronomy news, brought to you by

4
00:00:10.520 --> 00:00:13.360
astronomydaily IO and what

5
00:00:13.360 --> 00:00:13.600
a.

6
00:00:13.600 --> 00:00:16.520
Anna: Day we have for you today, Avery. If you were

7
00:00:16.520 --> 00:00:18.720
lucky enough to catch the auroras last night,

8
00:00:18.720 --> 00:00:20.240
you know what we're leading with.

9
00:00:20.640 --> 00:00:22.960
Avery: Absolutely, Anna. We're following up on

10
00:00:22.960 --> 00:00:25.880
yesterday's story about that powerful X class

11
00:00:25.880 --> 00:00:28.800
solar flare and the coronal mass ejection

12
00:00:28.800 --> 00:00:31.760
that was racing toward Earth. Well, it hit

13
00:00:32.140 --> 00:00:33.340
and it hit hard.

14
00:00:33.740 --> 00:00:36.620
Anna: That's right. We've got stunning photos from

15
00:00:36.620 --> 00:00:38.780
around the world of the resulting northern

16
00:00:38.780 --> 00:00:41.420
lights. And a retirement announcement from a

17
00:00:41.420 --> 00:00:44.420
legendary NASA astronaut. An incredible

18
00:00:44.420 --> 00:00:46.860
space rescue story from China, and some

19
00:00:46.860 --> 00:00:48.820
exciting updates from the commercial space

20
00:00:48.820 --> 00:00:49.180
sector.

21
00:00:49.660 --> 00:00:51.700
Avery: Plus, we'll tell you about NASA's latest

22
00:00:51.700 --> 00:00:53.860
mission that's preparing to study the Sun's

23
00:00:53.860 --> 00:00:56.500
most powerful eruptions. And we'll take you

24
00:00:56.500 --> 00:00:58.820
on a cosmic journey billions of years into

25
00:00:58.820 --> 00:01:01.500
the past with some fascinating new telescope

26
00:01:01.500 --> 00:01:02.100
observations.

27
00:01:02.740 --> 00:01:05.580
Anna: So grab your coffee, settle in, and let's get

28
00:01:05.580 --> 00:01:06.980
into today's space news.

29
00:01:07.300 --> 00:01:09.500
Avery: All right, Anna, let's dive into our lead

30
00:01:09.500 --> 00:01:12.460
story and what a spectacular show it

31
00:01:12.460 --> 00:01:14.900
was yesterday. We told our listeners about

32
00:01:14.900 --> 00:01:17.580
that x 1.9 solar flare and

33
00:01:17.580 --> 00:01:19.780
coronal mass ejection headed our way.

34
00:01:20.260 --> 00:01:23.060
Well, it arrived right on schedule. In fact,

35
00:01:23.140 --> 00:01:24.020
a little early.

36
00:01:24.420 --> 00:01:26.990
Anna: It certainly did, Avery. The CME

37
00:01:27.150 --> 00:01:29.310
slammed into Earth's magnetic field on

38
00:01:29.310 --> 00:01:32.310
January 19th at around 2:38pm

39
00:01:32.310 --> 00:01:35.230
Eastern Time. And it packed quite a punch.

40
00:01:35.630 --> 00:01:38.150
Space weather forecasters at NOAA's Space

41
00:01:38.150 --> 00:01:40.430
Weather Prediction center confirmed that

42
00:01:40.430 --> 00:01:42.830
geomagnetic conditions escalated to

43
00:01:42.830 --> 00:01:45.390
G4 level. That's classified as

44
00:01:45.390 --> 00:01:47.230
severe on their five point scale.

45
00:01:47.630 --> 00:01:49.870
Avery: And the results were absolutely

46
00:01:49.870 --> 00:01:52.190
breathtaking. What made the CME

47
00:01:52.350 --> 00:01:55.190
particularly noteworthy was just how fast it

48
00:01:55.190 --> 00:01:57.830
traveled. Remember, it was ejected from the

49
00:01:57.830 --> 00:02:00.710
sun on January 18th during that powerful

50
00:02:00.710 --> 00:02:03.590
solar flare, which means it covered roughly

51
00:02:03.590 --> 00:02:06.430
93 million miles in just over a day.

52
00:02:06.750 --> 00:02:08.350
That's exceptionally quick.

53
00:02:08.750 --> 00:02:11.510
Anna: The aurora displays that followed were truly

54
00:02:11.510 --> 00:02:14.150
global in scope. We're seeing reports and

55
00:02:14.150 --> 00:02:16.630
photographs from locations that rarely get to

56
00:02:16.630 --> 00:02:18.590
witness the northern lights. One

57
00:02:18.590 --> 00:02:21.350
photographer, Greg Gage, captured stunning

58
00:02:21.350 --> 00:02:24.180
red auroras from Deming, New Mexico. That's

59
00:02:24.180 --> 00:02:26.700
at 32 degrees latitude. He told

60
00:02:26.700 --> 00:02:29.500
Space.com he was on vacation there and never

61
00:02:29.500 --> 00:02:31.820
expected to see auroras that far south.

62
00:02:32.380 --> 00:02:34.700
Avery: That's incredible. And it wasn't just North

63
00:02:34.700 --> 00:02:37.180
America. The displays stretched across

64
00:02:37.260 --> 00:02:40.019
Europe, Asia and beyond. In

65
00:02:40.019 --> 00:02:42.860
Germany, vivid red and green auroras danced

66
00:02:42.860 --> 00:02:45.100
above the River Mughelspree near Berlin,

67
00:02:45.580 --> 00:02:48.140
Hungary, saw intense red and green hues

68
00:02:48.140 --> 00:02:49.740
filling the skies over the village of.

69
00:02:49.740 --> 00:02:52.660
Anna: Oboivar, uh, France had some particularly

70
00:02:52.660 --> 00:02:55.260
eerie displays with rich magenta

71
00:02:55.260 --> 00:02:57.740
auroras above Brittany. And in China, the

72
00:02:57.740 --> 00:02:59.940
northern lights were visible Above Beiji

73
00:02:59.940 --> 00:03:02.300
village in Heilongjiang province, with

74
00:03:02.300 --> 00:03:04.420
photographers capturing everything from

75
00:03:04.420 --> 00:03:07.300
magenta to green to even hints of blue

76
00:03:07.300 --> 00:03:08.420
in the curtains of light.

77
00:03:08.820 --> 00:03:10.820
Avery: What's particularly interesting about these

78
00:03:10.820 --> 00:03:13.660
displays Is the variety of colors. The

79
00:03:13.660 --> 00:03:16.260
red auroras we're seeing indicate that oxygen

80
00:03:16.260 --> 00:03:19.220
atoms at, uh, very high altitudes around 200

81
00:03:19.300 --> 00:03:22.100
to 300 miles up, are being energized.

82
00:03:22.730 --> 00:03:25.170
The green we typically associate with auroras

83
00:03:25.170 --> 00:03:28.050
Comes from oxygen at lower altitudes, While

84
00:03:28.050 --> 00:03:30.090
any blue would be from nitrogen.

85
00:03:30.330 --> 00:03:32.530
Anna: The geomagnetic conditions throughout the

86
00:03:32.530 --> 00:03:35.450
night Were quite dynamic, too. Storm levels

87
00:03:35.450 --> 00:03:37.959
fluctuated between G1, G2,

88
00:03:38.114 --> 00:03:40.810
G3, and G4 as the CME

89
00:03:40.970 --> 00:03:42.810
passed through Earth's magnetic field.

90
00:03:43.130 --> 00:03:45.810
According to the UK Met Office, this kept

91
00:03:45.810 --> 00:03:48.250
Earth's magnetic field In a highly disturbed

92
00:03:48.250 --> 00:03:51.170
state for hours, Producing repeated surges of

93
00:03:51.170 --> 00:03:52.250
auroral activity.

94
00:03:52.690 --> 00:03:54.570
Avery: And there's more good news for aurora

95
00:03:54.570 --> 00:03:57.450
watchers. While geomagnetic activity Is

96
00:03:57.450 --> 00:04:00.370
expected to gradually ease, Forecasters

97
00:04:00.370 --> 00:04:02.610
say conditions remain unsettled. That means

98
00:04:02.610 --> 00:04:04.570
there's still a chance the northern lights

99
00:04:04.570 --> 00:04:06.490
could make another appearance tonight if

100
00:04:06.490 --> 00:04:08.290
solar, uh, wind conditions cooperate.

101
00:04:08.610 --> 00:04:11.050
Anna: So if you missed last night's show, keep

102
00:04:11.050 --> 00:04:13.450
those cameras charged and your aurora alert

103
00:04:13.450 --> 00:04:16.170
apps turned on. The sun is clearly in an

104
00:04:16.170 --> 00:04:18.730
active phase, and we could see more displays

105
00:04:18.730 --> 00:04:20.210
in the coming days and weeks.

106
00:04:20.849 --> 00:04:23.369
Avery: Absolutely. And this really highlights why we

107
00:04:23.369 --> 00:04:25.889
track space weather so closely. While these

108
00:04:25.889 --> 00:04:28.809
auroras are beautiful, the same geomagnetic

109
00:04:28.809 --> 00:04:31.369
storms can affect satellites, power grids,

110
00:04:31.369 --> 00:04:34.089
and radio communications. It's a reminder of

111
00:04:34.089 --> 00:04:36.888
how our technological society is connected

112
00:04:36.888 --> 00:04:39.809
to what's happening 93 million miles away

113
00:04:39.889 --> 00:04:40.609
on the sun.

114
00:04:41.249 --> 00:04:43.689
Anna: Moving on to our next story. Avery. And this

115
00:04:43.689 --> 00:04:46.049
one marks the end of an era. After

116
00:04:46.129 --> 00:04:48.449
27 years of distinguished service,

117
00:04:49.060 --> 00:04:51.620
NASA astronaut Suni Williams has officially

118
00:04:51.620 --> 00:04:53.220
retired from the agency.

119
00:04:53.860 --> 00:04:56.020
Avery: This is definitely a significant moment.

120
00:04:56.020 --> 00:04:58.540
Anna, uh, Suni Williams has been such an

121
00:04:58.540 --> 00:05:01.180
inspiring figure in human spaceflight. Her

122
00:05:01.180 --> 00:05:04.106
retirement became effective on December 27,

123
00:05:04.294 --> 00:05:07.020
2025, though NASA just announced

124
00:05:07.020 --> 00:05:09.820
it this week. Let's talk about her remarkable

125
00:05:09.820 --> 00:05:10.420
achievements.

126
00:05:11.060 --> 00:05:13.660
Anna: Where do we even start? Over the course of

127
00:05:13.660 --> 00:05:15.940
her career, Williams logged an impressive

128
00:05:15.940 --> 00:05:18.820
608 days in space. That

129
00:05:18.820 --> 00:05:20.900
makes her second on the list for cumulative

130
00:05:20.900 --> 00:05:23.500
time and space by a NASA astronaut. She

131
00:05:23.500 --> 00:05:25.420
completed three missions to the International

132
00:05:25.580 --> 00:05:28.100
Space Station and held numerous records

133
00:05:28.100 --> 00:05:29.020
throughout her career.

134
00:05:29.340 --> 00:05:31.700
Avery: Her most recent mission was particularly

135
00:05:31.700 --> 00:05:34.100
interesting. Williams and fellow astronaut

136
00:05:34.100 --> 00:05:36.300
Butch Wilmore launched aboard Boeing

137
00:05:36.300 --> 00:05:39.020
Starliner spacecraft in June 2024

138
00:05:39.340 --> 00:05:41.740
as part of NASA's Boeing Crew Flight Test

139
00:05:41.740 --> 00:05:44.580
mission, both tied for sixth place on the

140
00:05:44.580 --> 00:05:46.740
list. Of longest single spaceflight by an

141
00:05:46.740 --> 00:05:49.490
American logging 286

142
00:05:49.490 --> 00:05:51.850
days during their combined Starliner and

143
00:05:51.850 --> 00:05:53.450
SpaceX Crew 9 missions.

144
00:05:53.930 --> 00:05:55.850
Anna: That's right. And during that mission,

145
00:05:55.850 --> 00:05:57.890
Williams once again took command of the space

146
00:05:57.890 --> 00:06:00.810
station for Expedition 72. She's also

147
00:06:00.810 --> 00:06:03.489
renowned for her spacewalking expertise. She

148
00:06:03.489 --> 00:06:06.370
completed nine spacewalks totaling 62

149
00:06:06.370 --> 00:06:08.650
hours and six minutes over her career.

150
00:06:09.050 --> 00:06:11.330
Avery: That gives her the record for most spacewalk

151
00:06:11.330 --> 00:06:14.050
time by a woman and fourth most on the all

152
00:06:14.050 --> 00:06:16.410
time cumulative spacewalk duration list.

153
00:06:16.950 --> 00:06:19.550
Oh, and here's a fun fact. She was also the

154
00:06:19.550 --> 00:06:21.990
first person to run a marathon in space.

155
00:06:22.630 --> 00:06:25.150
Anna: Beyond her spaceflight experience, Williams

156
00:06:25.150 --> 00:06:27.710
held numerous important roles at NASA. She

157
00:06:27.710 --> 00:06:29.710
served as Deputy Chief of the Astronaut

158
00:06:29.710 --> 00:06:32.270
Office, was Director of Operations in Star

159
00:06:32.270 --> 00:06:34.750
City, Russia, and most recently helped

160
00:06:34.750 --> 00:06:37.390
establish a helicopter training platform to

161
00:06:37.390 --> 00:06:39.830
prepare astronauts for future moon landings.

162
00:06:40.470 --> 00:06:43.190
Avery: NASA Administrator Jared Eichman had some

163
00:06:43.190 --> 00:06:45.740
wonderful words about her legacy. He called

164
00:06:45.740 --> 00:06:48.740
her a trailblazer in human spaceflight whose

165
00:06:48.740 --> 00:06:51.140
work advancing science and technology has

166
00:06:51.140 --> 00:06:53.420
laid the foundation for Artemis missions to

167
00:06:53.420 --> 00:06:55.820
the moon and future missions to Mars.

168
00:06:56.300 --> 00:06:59.060
Anna: It's worth noting her background too. She's a

169
00:06:59.060 --> 00:07:01.900
retired US Navy captain and an accomplished

170
00:07:01.900 --> 00:07:04.900
pilot with more than 4,000 flight hours in

171
00:07:04.900 --> 00:07:07.660
40 different aircraft. She holds a bachelor's

172
00:07:07.660 --> 00:07:09.580
degree in Physical science from the United

173
00:07:09.580 --> 00:07:12.300
States Naval Academy and a master's degree in

174
00:07:12.300 --> 00:07:13.100
Engineering Management.

175
00:07:13.950 --> 00:07:16.270
Avery: In her retirement statement, Williams said,

176
00:07:16.590 --> 00:07:19.190
anyone who knows me knows that space is my

177
00:07:19.190 --> 00:07:21.990
absolute favorite place to be. She expressed

178
00:07:21.990 --> 00:07:24.870
gratitude for her 27 year career and the

179
00:07:24.870 --> 00:07:27.070
support she received from her colleagues and

180
00:07:27.070 --> 00:07:29.350
mentioned she's excited to watch NASA make

181
00:07:29.350 --> 00:07:31.510
history as the agency continues its

182
00:07:31.510 --> 00:07:32.430
exploration efforts.

183
00:07:32.910 --> 00:07:35.030
Anna: It's a well deserved retirement for someone

184
00:07:35.030 --> 00:07:37.030
who has contributed so much to human

185
00:07:37.030 --> 00:07:39.070
spaceflight. Her achievements will

186
00:07:39.070 --> 00:07:41.470
undoubtedly inspire the next generation of

187
00:07:41.470 --> 00:07:43.310
astronauts and space explorers.

188
00:07:43.920 --> 00:07:46.120
Avery: Alright, Anna, um, our next story is quite

189
00:07:46.120 --> 00:07:48.520
dramatic. It involves a successful space

190
00:07:48.520 --> 00:07:51.080
rescue, emergency repairs, and some

191
00:07:51.080 --> 00:07:53.360
impressive quick thinking by China's space

192
00:07:53.360 --> 00:07:53.760
program.

193
00:07:54.400 --> 00:07:57.040
Anna: This is really a remarkable story, avery.

194
00:07:57.120 --> 00:08:00.000
China's Shenzhou 20 capsule safely

195
00:08:00.000 --> 00:08:02.997
landed in Inner Mongolia on January 19,

196
00:08:03.136 --> 00:08:06.080
2026 after spending 270

197
00:08:06.080 --> 00:08:08.760
days in orbit. But the journey

198
00:08:08.760 --> 00:08:11.510
back wasn't exactly routine. This

199
00:08:11.510 --> 00:08:13.550
mission became one of the most technically

200
00:08:13.550 --> 00:08:15.950
demanding in China's human spaceflight

201
00:08:15.950 --> 00:08:16.310
history.

202
00:08:16.950 --> 00:08:19.870
Avery: The Shenzhou 20 was originally launched back

203
00:08:19.870 --> 00:08:22.830
on April 24, 2025 from

204
00:08:22.830 --> 00:08:25.590
the Jiuquan Satellite Launch Center. It was

205
00:08:25.590 --> 00:08:27.509
expected to complete its mission and return

206
00:08:27.510 --> 00:08:30.310
in November 2025. But then

207
00:08:30.310 --> 00:08:32.710
came the complication. A, uh, suspected

208
00:08:32.870 --> 00:08:35.390
impact with space debris damaged one of the

209
00:08:35.390 --> 00:08:36.550
capsule's portholes.

210
00:08:37.300 --> 00:08:40.140
Anna: Talk about a critical issue. A cracked

211
00:08:40.140 --> 00:08:42.980
porthole on a spacecraft is serious business,

212
00:08:43.460 --> 00:08:45.220
especially when you're thinking about the

213
00:08:45.220 --> 00:08:48.100
intense heat and forces of re entry through

214
00:08:48.100 --> 00:08:50.940
Earth's atmosphere. So how did China's

215
00:08:50.940 --> 00:08:52.180
space program respond?

216
00:08:52.739 --> 00:08:54.980
Avery: With remarkable speed and coordination.

217
00:08:55.620 --> 00:08:57.820
First they authorized astronauts aboard the

218
00:08:57.820 --> 00:09:00.460
Shenzhou 21 spacecraft to photograph the

219
00:09:00.460 --> 00:09:02.700
damaged porthole during a spacewalk on

220
00:09:02.700 --> 00:09:05.390
December 9. They used high definition

221
00:09:05.390 --> 00:09:07.630
cameras to get a detailed diagnosis of the

222
00:09:07.630 --> 00:09:07.910
problem.

223
00:09:08.470 --> 00:09:11.110
Anna: And then came an unprecedented move.

224
00:09:11.350 --> 00:09:14.070
China launched Shenzhou 22 on

225
00:09:14.070 --> 00:09:16.910
November 25. Marking the first rapid

226
00:09:16.910 --> 00:09:19.390
response emergency deployment in China's

227
00:09:19.390 --> 00:09:22.350
space history. This uncrewed craft delivered

228
00:09:22.350 --> 00:09:24.710
a specially engineered repair device

229
00:09:24.870 --> 00:09:27.070
designed to enhance the capsule's heat

230
00:09:27.070 --> 00:09:29.430
resistance and sealing for re entry.

231
00:09:30.180 --> 00:09:32.340
Avery: Meanwhile, for safety reasons, the crew of

232
00:09:32.340 --> 00:09:34.940
Shenzhou 20 was evacuated ahead of

233
00:09:34.940 --> 00:09:37.460
schedule. They returned aboard Shenzhou

234
00:09:37.460 --> 00:09:40.340
21 on November 14th in what the China

235
00:09:40.340 --> 00:09:43.140
Manned Space Agency called an emergency

236
00:09:43.140 --> 00:09:43.860
reroute.

237
00:09:44.420 --> 00:09:46.980
Anna: So uh, the Shenzhou 20 capsule came home

238
00:09:46.980 --> 00:09:49.700
empty, but it came home safe. According

239
00:09:49.700 --> 00:09:52.300
to cgtn, the China Manned Space

240
00:09:52.300 --> 00:09:54.660
Agency declared the mission uh, a complete

241
00:09:54.660 --> 00:09:57.050
success after an on site inspection

242
00:09:57.210 --> 00:09:59.450
confirmed the capsule was in good condition

243
00:09:59.450 --> 00:10:01.370
despite everything it went through.

244
00:10:01.930 --> 00:10:03.770
Avery: What really stands out here is the

245
00:10:03.770 --> 00:10:06.170
operational capability. This demonstrates

246
00:10:06.570 --> 00:10:09.370
China executed three overlapping missions,

247
00:10:09.450 --> 00:10:12.330
Shenzhou 20, 21 and 22

248
00:10:12.570 --> 00:10:15.250
over a span of just weeks. That shows

249
00:10:15.250 --> 00:10:17.570
significant operational depth and uh, the

250
00:10:17.570 --> 00:10:19.690
ability to respond to emergencies in space.

251
00:10:20.330 --> 00:10:22.690
Anna: Absolutely. And it's not just about the

252
00:10:22.690 --> 00:10:25.540
technical achievement. This validates China's

253
00:10:25.540 --> 00:10:27.580
long term approach to maintaining crew

254
00:10:27.580 --> 00:10:30.140
vehicles in orbit. The Shenzhou 20

255
00:10:30.220 --> 00:10:32.860
stayed up there for 270 days

256
00:10:32.940 --> 00:10:35.260
which demonstrates the reliability of their

257
00:10:35.260 --> 00:10:36.460
spacecraft systems.

258
00:10:36.860 --> 00:10:39.020
Avery: This mission also underscores something we

259
00:10:39.020 --> 00:10:41.780
talk about often, the very real danger

260
00:10:41.780 --> 00:10:44.780
posed by space debris. Even small particles

261
00:10:44.780 --> 00:10:47.100
traveling at orbital velocities can cause

262
00:10:47.100 --> 00:10:49.660
significant damage as we saw here with the

263
00:10:49.660 --> 00:10:50.540
porthole crack.

264
00:10:51.130 --> 00:10:53.770
Anna: And China's ability to handle this situation

265
00:10:53.930 --> 00:10:56.370
adds to their growing reputation in space

266
00:10:56.370 --> 00:10:59.090
exploration. They're now capable of managing

267
00:10:59.090 --> 00:11:01.930
multi vessel operations under pressure with

268
00:11:01.930 --> 00:11:04.610
modular mission architecture and long term

269
00:11:04.610 --> 00:11:05.930
crew support capabilities.

270
00:11:06.650 --> 00:11:09.250
Avery: Congratulations to all involved in this very

271
00:11:09.250 --> 00:11:10.570
successful mission. In the end.

272
00:11:11.130 --> 00:11:13.490
Anna: Moving on to our next story, Avery. And we're

273
00:11:13.490 --> 00:11:16.290
heading to West Texas where Blue Origin is

274
00:11:16.290 --> 00:11:18.610
preparing for its next suborbital space

275
00:11:18.610 --> 00:11:19.530
tourism mission.

276
00:11:20.060 --> 00:11:22.100
Avery: That's right Anna. Uh, Blue Origin is

277
00:11:22.100 --> 00:11:24.660
scheduled to launch six space tourists on its

278
00:11:24.660 --> 00:11:27.596
NS38 mission this Thursday, January

279
00:11:27.724 --> 00:11:30.260
22nd. The launch window opens at

280
00:11:30.260 --> 00:11:32.620
9:30am Eastern Time. That's

281
00:11:32.620 --> 00:11:34.940
8:30am M local Texas time.

282
00:11:35.260 --> 00:11:37.660
Anna: This will be the 38th flight of Blue

283
00:11:37.660 --> 00:11:40.300
Origin's New Shepard rocket capsule system.

284
00:11:40.540 --> 00:11:43.420
And if all goes according to plan, the 17th

285
00:11:43.420 --> 00:11:45.830
crewed mission they've flown the mission

286
00:11:45.830 --> 00:11:47.910
follows the same profile we've seen before.

287
00:11:48.230 --> 00:11:50.870
About 10 to 12 minutes from liftoff to the

288
00:11:50.870 --> 00:11:52.870
capsule's parachute aided touchdown.

289
00:11:53.430 --> 00:11:55.910
Avery: During that brief but spectacular journey,

290
00:11:55.990 --> 00:11:58.110
passengers will experience a few minutes of

291
00:11:58.110 --> 00:12:00.190
weightlessness and get to see Earth against

292
00:12:00.190 --> 00:12:03.070
the blackness of space from an altitude above

293
00:12:03.070 --> 00:12:05.270
the Karman Line, which is generally

294
00:12:05.270 --> 00:12:07.190
recognized as the boundary of space.

295
00:12:07.830 --> 00:12:10.510
Anna: Now, let's talk about who's flying. We have

296
00:12:10.510 --> 00:12:12.950
entrepreneur and pilot Tim Drexler,

297
00:12:13.420 --> 00:12:16.260
retired obstetrician and gynecologist Linda

298
00:12:16.260 --> 00:12:18.980
Edwards, real estate developer and investor

299
00:12:18.980 --> 00:12:21.540
Elaine Fernandez, entrepreneur and

300
00:12:21.540 --> 00:12:24.340
technologist Alberto Gutierrez, and

301
00:12:24.340 --> 00:12:27.340
retired US Air Force Colonel Jim Hendren,

302
00:12:27.340 --> 00:12:30.100
who founded Hendren Plastics, Inc. And

303
00:12:30.100 --> 00:12:31.100
there's an interesting.

304
00:12:31.100 --> 00:12:33.700
Avery: Late addition to the crew manifest. Blue

305
00:12:33.700 --> 00:12:36.420
Origin just announced that Lara Stiles, who

306
00:12:36.420 --> 00:12:38.860
is Blue Origin's director of New Shepard

307
00:12:38.860 --> 00:12:41.140
launch Operations, will be flying on this

308
00:12:41.140 --> 00:12:41.500
mission.

309
00:12:42.160 --> 00:12:44.240
Anna: That's a pretty cool opportunity for someone

310
00:12:44.240 --> 00:12:46.400
who's been so involved in making these

311
00:12:46.400 --> 00:12:49.120
missions happen. Dials is actually a late

312
00:12:49.120 --> 00:12:51.400
replacement for a passenger who had to drop

313
00:12:51.400 --> 00:12:53.760
out due to illness. Though that person will

314
00:12:53.760 --> 00:12:55.280
get to fly on a future mission.

315
00:12:55.680 --> 00:12:58.080
Avery: Blue Origin has been steadily building their

316
00:12:58.080 --> 00:13:00.120
flight rate. Just last month, they made

317
00:13:00.120 --> 00:13:02.560
history by flying the first wheelchair user

318
00:13:02.560 --> 00:13:05.480
to space on their NS37 mission. They're

319
00:13:05.480 --> 00:13:07.480
really demonstrating that spaceflight can be

320
00:13:07.480 --> 00:13:09.520
accessible to a diverse range of people.

321
00:13:10.250 --> 00:13:12.930
Anna: Now, Blue Origin hasn't publicly disclosed

322
00:13:12.930 --> 00:13:15.250
their ticket prices, but we know their main

323
00:13:15.250 --> 00:13:17.530
competitor Virgin Galactic charges

324
00:13:17.770 --> 00:13:20.410
$600,000 per seat for similar

325
00:13:20.410 --> 00:13:23.290
suborbital flights. So we can probably assume

326
00:13:23.290 --> 00:13:25.210
Blue Origin's prices are in that same

327
00:13:25.210 --> 00:13:25.850
ballpark.

328
00:13:26.170 --> 00:13:28.410
Avery: If you want to watch this launch, Blue Origin

329
00:13:28.410 --> 00:13:30.210
typically livestreams our missions, and

330
00:13:30.210 --> 00:13:32.650
Space.com will likely carry the feat as well.

331
00:13:32.890 --> 00:13:35.130
It's always exciting to watch these launches.

332
00:13:35.130 --> 00:13:37.570
That New Shepard rocket is quite a sight to

333
00:13:37.570 --> 00:13:37.850
see.

334
00:13:38.450 --> 00:13:41.370
Anna: Absolutely. And it's worth noting how routine

335
00:13:41.370 --> 00:13:43.890
these launches are becoming. Blue Origin is

336
00:13:43.890 --> 00:13:45.650
really building up their experience with

337
00:13:45.650 --> 00:13:48.090
regular crewed flights, which is essential

338
00:13:48.090 --> 00:13:50.050
for the commercial space tourism industry.

339
00:13:50.610 --> 00:13:52.850
Avery: Our next story takes us from suborbital

340
00:13:52.850 --> 00:13:55.210
tourism to cutting edge heliophysics

341
00:13:55.210 --> 00:13:55.490
research.

342
00:13:55.490 --> 00:13:58.370
Anna. Uh, NASA Sunrise, that's the Sun

343
00:13:58.370 --> 00:14:01.290
Radio Interometer Space Experiment is moving

344
00:14:01.290 --> 00:14:03.770
closer to its launch later this year after

345
00:14:03.770 --> 00:14:06.250
successfully completing a rigorous series of

346
00:14:06.250 --> 00:14:06.680
tests.

347
00:14:07.310 --> 00:14:09.870
Anna: This is such a fascinating mission. Avery

348
00:14:10.030 --> 00:14:12.750
Sunrise consists of six smallsats.

349
00:14:12.830 --> 00:14:15.350
They're about the size of a toaster oven that

350
00:14:15.350 --> 00:14:18.270
will fly in formation to act as one giant

351
00:14:18.270 --> 00:14:20.270
radio telescope studying the sun.

352
00:14:20.750 --> 00:14:23.390
Avery: That's the clever part. These six smallsats

353
00:14:23.390 --> 00:14:25.990
will orbit at about 22,000 miles

354
00:14:25.990 --> 00:14:28.270
altitude, which is geosynchronous orbit.

355
00:14:28.430 --> 00:14:30.670
Flying up to 10 miles apart from each other.

356
00:14:30.990 --> 00:14:33.190
By combining their observations Using a

357
00:14:33.190 --> 00:14:35.580
technique called interferometry, they'll

358
00:14:35.580 --> 00:14:38.020
create what's essentially A single large

359
00:14:38.100 --> 00:14:39.620
radio telescope in space.

360
00:14:40.180 --> 00:14:42.820
Anna: And what will they be looking at? Solar

361
00:14:42.820 --> 00:14:45.580
radio bursts. These bursts are generated

362
00:14:45.580 --> 00:14:48.180
by solar energetic particle events Deep

363
00:14:48.180 --> 00:14:51.180
within the sun's atmosphere, or corona. In

364
00:14:51.180 --> 00:14:53.700
extreme cases, these events could pose

365
00:14:53.700 --> 00:14:56.260
radiation hazards to unprotected astronauts

366
00:14:56.260 --> 00:14:57.700
and damaged satellites.

367
00:14:58.020 --> 00:15:00.300
Avery: The spacecraft were built At Utah State

368
00:15:00.300 --> 00:15:02.700
University's Space Dynamics laboratory in

369
00:15:02.700 --> 00:15:05.290
Logan, Utah, and they just completed what's

370
00:15:05.290 --> 00:15:07.410
described As a rigorous testing campaign.

371
00:15:07.890 --> 00:15:10.250
This included thermal vacuum testing to

372
00:15:10.250 --> 00:15:13.210
simulate orbital conditions, Electromagnetic

373
00:15:13.210 --> 00:15:15.290
compatibility testing to ensure the

374
00:15:15.290 --> 00:15:17.610
electronic systems Won't interfere With the

375
00:15:17.610 --> 00:15:20.530
sensitive instruments, and most dramatically,

376
00:15:20.850 --> 00:15:22.050
vibration testing.

377
00:15:22.210 --> 00:15:25.010
Anna: The vibration testing is crucial because

378
00:15:25.010 --> 00:15:27.490
launch is an incredibly violent event.

379
00:15:28.130 --> 00:15:30.930
Jim Lux, the Sunrise project manager at

380
00:15:30.930 --> 00:15:33.820
NASA's Jet Propulsion Laboratory, Explained

381
00:15:33.820 --> 00:15:35.860
that each spacecraft was loaded with

382
00:15:35.860 --> 00:15:38.820
propellant to match its launch mass and then

383
00:15:38.820 --> 00:15:41.460
subjected to vibration testing in all three

384
00:15:41.460 --> 00:15:42.060
axes.

385
00:15:42.380 --> 00:15:44.540
Avery: They wanted to make the simulated vibrations

386
00:15:44.540 --> 00:15:46.900
as true to the actual launch conditions as

387
00:15:46.900 --> 00:15:49.180
possible. And here's the important part.

388
00:15:49.580 --> 00:15:51.940
Pre and post test functional checks were

389
00:15:51.940 --> 00:15:54.700
performed and all six spacecraft passed with

390
00:15:54.700 --> 00:15:55.660
flying colors.

391
00:15:55.980 --> 00:15:58.180
Anna: The mission is scheduled to launch From Cape

392
00:15:58.180 --> 00:16:00.460
Canaveral Space Force Station in Florida

393
00:16:00.540 --> 00:16:03.460
Aboard a, uh ULA launch Vulcan Centaur

394
00:16:03.460 --> 00:16:06.190
rocket As a rideshare mission. Once in orbit,

395
00:16:06.190 --> 00:16:08.910
each satellite will deploy four telescoping

396
00:16:08.910 --> 00:16:11.390
antenna booms about 10ft long,

397
00:16:11.550 --> 00:16:13.630
forming an X shaped configuration.

398
00:16:14.110 --> 00:16:16.830
Avery: Sue Lepre, the sunrise principal investigator

399
00:16:16.830 --> 00:16:19.110
at the University of Michigan, Points out

400
00:16:19.110 --> 00:16:21.390
that these solar radio bursts Are triggered

401
00:16:21.390 --> 00:16:23.830
when vast quantities of energy Stored in the

402
00:16:23.830 --> 00:16:26.550
sun's magnetic field Accelerate solar

403
00:16:26.550 --> 00:16:29.030
particles to high speeds. Tracking these

404
00:16:29.030 --> 00:16:31.150
events will help space agencies Protect

405
00:16:31.150 --> 00:16:32.590
astronauts and spacecraft.

406
00:16:33.180 --> 00:16:35.220
Anna: And this mission will work in conjunction

407
00:16:35.220 --> 00:16:37.660
with other NASA heliophysics missions like

408
00:16:37.660 --> 00:16:40.300
the Solar Terrestrial Relations Observatory,

409
00:16:40.540 --> 00:16:43.060
the Parker Solar probe, and Solar

410
00:16:43.060 --> 00:16:44.540
Orbiter, which is an international

411
00:16:44.780 --> 00:16:46.540
cooperative mission with esa.

412
00:16:46.700 --> 00:16:48.700
Avery: It's exciting to see these missions coming

413
00:16:48.700 --> 00:16:51.340
together Between Parker Solar Probe diving

414
00:16:51.340 --> 00:16:54.260
close to the sun, Solar Orbiter studying the

415
00:16:54.260 --> 00:16:57.140
polar regions, and now Sunrise tracking radio

416
00:16:57.140 --> 00:16:59.510
bursts from Earth orbit. We're building a

417
00:16:59.510 --> 00:17:01.790
comprehensive picture of our star's behavior.

418
00:17:02.270 --> 00:17:05.230
Anna: And now for our final story. Avery. We're

419
00:17:05.230 --> 00:17:07.350
going to talk about something that's never

420
00:17:07.350 --> 00:17:09.390
been seen before in quite this

421
00:17:10.190 --> 00:17:12.750
Planetary systems in their awkward

422
00:17:12.830 --> 00:17:13.790
teenage years.

423
00:17:15.310 --> 00:17:17.910
Avery: Love that description, Anna. Astronomers

424
00:17:17.910 --> 00:17:20.110
using the Atacama Large Millimeter

425
00:17:20.190 --> 00:17:23.150
Submillimeter Array, better known as Alma,

426
00:17:23.310 --> 00:17:25.990
have captured the most detailed images ever

427
00:17:25.990 --> 00:17:28.769
of 24 debris disks. These are the

428
00:17:28.769 --> 00:17:31.369
dusty belts left behind after planets have

429
00:17:31.369 --> 00:17:32.249
finished forming.

430
00:17:32.729 --> 00:17:35.569
Anna: The survey is called arcs, which stands for

431
00:17:35.569 --> 00:17:37.609
the ALMA Survey to Resolve

432
00:17:37.609 --> 00:17:39.769
Exoker belt substructures.

433
00:17:40.169 --> 00:17:42.689
Meredith Hughes, an associate professor at

434
00:17:42.689 --> 00:17:45.209
Wesleyan University and co principal

435
00:17:45.209 --> 00:17:47.609
investigator, explains it perfectly.

436
00:17:47.849 --> 00:17:50.729
We've often seen the baby pictures of planets

437
00:17:50.729 --> 00:17:53.609
forming, but until now, the teenage years

438
00:17:53.609 --> 00:17:55.209
have been a missing link.

439
00:17:56.000 --> 00:17:58.640
Avery: And just like human teenagers, these systems

440
00:17:58.640 --> 00:18:00.720
turned out to be quite dramatic. The

441
00:18:00.720 --> 00:18:03.360
observations revealed incredible diversity.

442
00:18:03.600 --> 00:18:06.440
Not just simple rings, but multi ring

443
00:18:06.440 --> 00:18:09.200
belts, wide smooth halos, sharp

444
00:18:09.200 --> 00:18:12.000
edges, and even unexpected arcs and clumps.

445
00:18:12.480 --> 00:18:15.040
Anna: This phase is really important because these

446
00:18:15.040 --> 00:18:17.680
debris disks represent what's called the

447
00:18:17.680 --> 00:18:19.960
collision dominated phase of planet

448
00:18:19.960 --> 00:18:22.530
formation. Think of it like our own solar

449
00:18:22.530 --> 00:18:25.250
system's Kuiper Belt, that ring of icy

450
00:18:25.250 --> 00:18:28.250
debris beyond Neptune that preserves a record

451
00:18:28.250 --> 00:18:30.770
of massive collisions and planetary

452
00:18:30.770 --> 00:18:33.130
migrations from billions of years ago.

453
00:18:33.770 --> 00:18:36.090
Avery: Thomas Henning from the Max Planck Institute

454
00:18:36.090 --> 00:18:38.130
for Astronomy, another co principal

455
00:18:38.130 --> 00:18:40.530
investigator, notes that by characterizing

456
00:18:40.530 --> 00:18:42.890
these disk structures, they can find evidence

457
00:18:42.890 --> 00:18:45.490
pointing to the presence of planets. They're

458
00:18:45.490 --> 00:18:48.210
using ALMA alongside direct imaging and radio

459
00:18:48.210 --> 00:18:50.690
velocity studies to search for young planets

460
00:18:50.690 --> 00:18:51.450
in these systems.

461
00:18:52.150 --> 00:18:54.230
Anna: One of the challenges with studying debris

462
00:18:54.230 --> 00:18:56.630
disks is that they're incredibly faint,

463
00:18:56.870 --> 00:18:59.470
hundreds or even thousands of times dimmer

464
00:18:59.470 --> 00:19:02.270
than the bright gas rich disks where planets

465
00:19:02.270 --> 00:19:04.830
are actively being born. But alma's

466
00:19:04.830 --> 00:19:07.110
sensitivity and resolution made these.

467
00:19:07.110 --> 00:19:09.990
Avery: Observations possible, and the findings

468
00:19:09.990 --> 00:19:12.390
are fascinating. About one third of the

469
00:19:12.390 --> 00:19:15.150
observed disks show clear substructures,

470
00:19:15.150 --> 00:19:17.670
like multiple rings or distinct gaps.

471
00:19:18.240 --> 00:19:20.320
These could be legacy features from earlier

472
00:19:20.480 --> 00:19:22.960
planet building stages, or they could be

473
00:19:22.960 --> 00:19:25.280
sculpted by planets over much longer

474
00:19:25.280 --> 00:19:26.080
timescales.

475
00:19:26.560 --> 00:19:29.160
Anna: Perhaps most surprising, several of these

476
00:19:29.160 --> 00:19:32.160
disks retain gas much longer than expected.

477
00:19:32.800 --> 00:19:35.520
In some systems, this lingering gas might

478
00:19:35.520 --> 00:19:37.840
actually shape the chemistry of growing

479
00:19:37.840 --> 00:19:40.560
planets. Or it might push dust into

480
00:19:40.560 --> 00:19:41.600
wide halos.

481
00:19:42.320 --> 00:19:45.040
Avery: Many of the disks also show asymmetries and

482
00:19:45.040 --> 00:19:47.880
arcs. They're lopsided with bright arcs

483
00:19:47.880 --> 00:19:50.290
or eccentric shapes. This hints, uh, at

484
00:19:50.290 --> 00:19:52.490
gravitational interactions with unseen

485
00:19:52.490 --> 00:19:55.210
planets, leftover scars from planetary

486
00:19:55.210 --> 00:19:58.010
migration or interactions between the gas

487
00:19:58.010 --> 00:19:58.690
and dust.

488
00:19:59.250 --> 00:20:02.210
Anna: Luca Matra from Trinity College Dublin,

489
00:20:02.210 --> 00:20:04.730
another co principal investigator, puts it

490
00:20:04.730 --> 00:20:07.570
beautifully. These disks record a

491
00:20:07.570 --> 00:20:09.970
period when planetary orbits were being

492
00:20:09.970 --> 00:20:12.850
scrambled and huge impacts like the one

493
00:20:12.850 --> 00:20:15.570
that forged Earth's Moon were shaping young

494
00:20:15.570 --> 00:20:16.530
solar systems.

495
00:20:17.320 --> 00:20:19.480
Avery: And here's some great news for the scientific

496
00:20:19.480 --> 00:20:22.080
community. All of the ARC's observations and

497
00:20:22.080 --> 00:20:24.600
process data are being made freely available

498
00:20:24.680 --> 00:20:27.600
to astronomers worldwide. Which means we can

499
00:20:27.600 --> 00:20:29.840
expect even more discoveries from this data

500
00:20:29.840 --> 00:20:31.080
set in the coming years.

501
00:20:31.720 --> 00:20:34.280
Anna: Meredith Hughes sums up the significance

502
00:20:34.520 --> 00:20:37.440
perfectly. This project gives us a new

503
00:20:37.440 --> 00:20:39.840
lens for interpreting the craters on the

504
00:20:39.840 --> 00:20:42.640
Moon, the dynamics of the Kuiper Belt, and

505
00:20:42.640 --> 00:20:45.080
the growth of planets big and small.

506
00:20:45.690 --> 00:20:48.090
It's like adding the missing pages to the

507
00:20:48.090 --> 00:20:49.930
solar system's family album.

508
00:20:50.570 --> 00:20:52.610
Avery: Well, that wraps up today's episode of

509
00:20:52.610 --> 00:20:55.090
Astronomy Daily. What an incredible day of

510
00:20:55.090 --> 00:20:56.250
space news we've covered.

511
00:20:56.410 --> 00:20:59.050
Anna: From spectacular auroras, lighting up

512
00:20:59.050 --> 00:21:01.810
skies around the globe, to the retirement of

513
00:21:01.810 --> 00:21:04.610
a legendary astronaut, emergency space

514
00:21:04.610 --> 00:21:07.370
repairs by China, exciting commercial

515
00:21:07.370 --> 00:21:09.530
space launches, and groundbreaking

516
00:21:09.530 --> 00:21:12.490
observations of planetary systems, it's

517
00:21:12.490 --> 00:21:14.450
been quite a journey through the cosmos.

518
00:21:14.850 --> 00:21:16.810
Avery: And remember, if you want to stay up to date

519
