1
00:00:00.240 --> 00:00:04.120
Welcome to Astronomy Daily, your source for the latest space

2
00:00:04.160 --> 00:00:07.160
and astronomy news. I'm Anna and I'm Avery.

3
00:00:07.480 --> 00:00:11.199
It's Monday, February two, twenty twenty six, and we've got

4
00:00:11.199 --> 00:00:14.640
a fantastic line up of stories today, exploring everything from

5
00:00:14.679 --> 00:00:19.519
SpaceX's audacious satellite plans to ancient star maps hidden for centuries.

6
00:00:20.039 --> 00:00:24.640
That's right, Avery. Today we're diving into SpaceX's jaw dropping

7
00:00:24.679 --> 00:00:28.640
proposal to launch up to one million solar powered satellites,

8
00:00:29.000 --> 00:00:34.479
a remarkable archaeological discovery revealing Hipparcas's lost star catalog, and

9
00:00:34.600 --> 00:00:38.799
China's ambitious solar monitoring mission heading to a unique point

10
00:00:38.920 --> 00:00:39.479
in space.

11
00:00:39.960 --> 00:00:43.840
We'll also be discussing the giant star that fulled astronomers worldwide,

12
00:00:44.200 --> 00:00:47.479
Time magazine special tribute to the Artemis two crew, and

13
00:00:47.600 --> 00:00:51.920
remembering Gladys West, a hidden figure who helps shape GPS technology.

14
00:00:52.439 --> 00:00:56.079
It's going to be an incredible journey through space history, present,

15
00:00:56.240 --> 00:00:56.880
and future.

16
00:00:57.399 --> 00:01:00.679
So settle in and let's explore the cause most together.

17
00:01:01.159 --> 00:01:04.200
We're starting with what might be the most ambitious satellite

18
00:01:04.280 --> 00:01:08.640
constellation proposal ever conceived. SpaceX has filed with the Federal

19
00:01:08.680 --> 00:01:12.439
Communications Commission seeking approval to launch up to one million

20
00:01:12.560 --> 00:01:15.959
solar powered satellites that would function as data centers for

21
00:01:16.079 --> 00:01:17.280
artificial intelligence.

22
00:01:17.920 --> 00:01:23.079
One million satellites, Avery, that's absolutely staggering. To put that

23
00:01:23.159 --> 00:01:27.120
in perspective. There are currently around fifteen thousand man made

24
00:01:27.159 --> 00:01:31.560
satellites orbiting Earth. According to the European Space Agency. SpaceX

25
00:01:31.640 --> 00:01:35.480
is essentially proposing to increase that number by several orders

26
00:01:35.519 --> 00:01:36.400
of magnitude.

27
00:01:36.680 --> 00:01:39.560
The scale is mind boggling, Anna, and SpaceX isn't just

28
00:01:39.599 --> 00:01:43.000
framing this as a commercial venture. Their filing describes these

29
00:01:43.000 --> 00:01:46.519
satellites as the most efficient way to meet accelerating demand

30
00:01:46.560 --> 00:01:49.840
for AI computing power. But they go even further. They're

31
00:01:49.879 --> 00:01:52.599
calling it a first step towards becoming a Kardashev type

32
00:01:52.640 --> 00:01:56.239
to civilization, one that can harness the Sun's full power.

33
00:01:56.680 --> 00:01:59.680
That's quite the vision for our listeners who might not

34
00:01:59.760 --> 00:02:03.120
be familiar. The Kardashev scale is a method of measuring

35
00:02:03.159 --> 00:02:08.360
a civilization's technological advancement based on energy consumption. A Type

36
00:02:08.400 --> 00:02:11.680
two civilization would be able to harness all the energy

37
00:02:11.680 --> 00:02:15.680
output of its star. But let's talk practicalities here. The

38
00:02:15.840 --> 00:02:19.000
Verge has pointed out that the one million satellite number

39
00:02:19.319 --> 00:02:22.479
is unlikely to be approved outright and is probably a

40
00:02:22.479 --> 00:02:25.240
starting point for negotiation exactly.

41
00:02:25.479 --> 00:02:29.199
The FCC recently gave SpaceX permission to launch an additional

42
00:02:29.280 --> 00:02:33.199
seven thousand, five hundred and seventy five Starlink satellites, but

43
00:02:33.360 --> 00:02:36.879
the third authorization on the remaining fourteen thousand, nine hundred

44
00:02:36.879 --> 00:02:40.960
and eighty eight satellites proposed. So there's clearly regulatory caution

45
00:02:41.000 --> 00:02:44.759
about satellite proliferation, and there are very real concerns about

46
00:02:44.759 --> 00:02:47.120
space to briand and light pollution that come with such

47
00:02:47.280 --> 00:02:48.479
massive consolations.

48
00:02:48.960 --> 00:02:53.080
The timing is also interesting. Misfiling comes as Amazon is

49
00:02:53.120 --> 00:02:56.319
seeking an FCC extension on a deadline to have more

50
00:02:56.319 --> 00:02:59.800
than sixteen hundred satellites in orbit, citing a lack of

51
00:02:59.840 --> 00:03:04.919
available rockets. Meanwhile, SpaceX is reportedly considering a merger with

52
00:03:05.000 --> 00:03:09.280
two of Elon Musk's other companies, Tesla and Xai, ahead

53
00:03:09.280 --> 00:03:10.000
of going public.

54
00:03:10.479 --> 00:03:13.120
It really shows how the commercial space sector is evolving

55
00:03:13.159 --> 00:03:16.479
anna what was once the domain of governments is increasingly

56
00:03:16.479 --> 00:03:20.759
being driven by private companies with enormous ambitions. Whether SpaceX

57
00:03:20.759 --> 00:03:23.960
gets approval for anything close to a million satellites remains

58
00:03:24.000 --> 00:03:26.560
to be seen, but it is certainly signals where they

59
00:03:26.599 --> 00:03:27.719
think the future is headed.

60
00:03:28.120 --> 00:03:30.919
It's fascinating to think about, but we'll have to see

61
00:03:30.919 --> 00:03:34.919
how regulators balance innovation with the very real concerns about

62
00:03:34.960 --> 00:03:38.479
our orbital environment. Now, let's move from the future to

63
00:03:38.560 --> 00:03:39.520
the distant past.

64
00:03:40.000 --> 00:03:43.400
From cutting edge satellite technology, we're traveling back more than

65
00:03:43.400 --> 00:03:47.719
two thousand years to rediscover one of astronomy's greatest loss treasures.

66
00:03:48.199 --> 00:03:52.560
Scientists have successfully recovered fragments of the world's earliest star catalog,

67
00:03:52.960 --> 00:03:56.240
created by the ancient Greek astronomer Hipparchus, from a fifteen

68
00:03:56.319 --> 00:03:58.080
hundred year old manuscript.

69
00:03:58.240 --> 00:04:03.319
This is absolutely remarkable. Avery hip Arkas is widely considered

70
00:04:03.360 --> 00:04:07.120
the father of astronomy. He figured out how equinoxes shift,

71
00:04:07.439 --> 00:04:11.360
created a magnitude scale to rank star brightness, and tracked

72
00:04:11.360 --> 00:04:15.240
planetary motion, all more than two thousand years ago without

73
00:04:15.240 --> 00:04:19.439
any telescopes. But his actual star catalog had vanished from

74
00:04:19.519 --> 00:04:20.959
history until now.

75
00:04:21.560 --> 00:04:25.199
The manuscript is what's called a palimpsest, which means it's

76
00:04:25.319 --> 00:04:28.759
parchment that was wiped clean and reused. In this case,

77
00:04:28.839 --> 00:04:33.000
Hiparkas's original Greek text was erased and overwritten with Syriac

78
00:04:33.079 --> 00:04:36.839
religious writings of Saint John Klamacus, the original work was

79
00:04:36.879 --> 00:04:39.399
literally buried under six layers of ink.

80
00:04:40.120 --> 00:04:43.399
So how did researchers manage to read text that was

81
00:04:43.519 --> 00:04:48.800
intentionally erased centuries ago? That used some pretty sophisticated technology.

82
00:04:49.240 --> 00:04:53.360
A team led by Victor Geisenberg from Sorbonne University used

83
00:04:53.560 --> 00:04:58.000
X ray technology at the SALC National Accelerator Laboratory to

84
00:04:58.040 --> 00:05:00.480
scan eleven pages of the Man Script.

85
00:05:01.040 --> 00:05:04.199
The key was a Hiparkasis original inc had a different

86
00:05:04.279 --> 00:05:08.279
chemical composition than the later religious texts. The ancient ink

87
00:05:08.399 --> 00:05:11.199
was rich in calcium, which showed up clearly under X

88
00:05:11.279 --> 00:05:15.160
ray scanning. They used extremely short X ray pulses, each

89
00:05:15.399 --> 00:05:19.279
just ten milliseconds long, focused on areas no wider than

90
00:05:19.279 --> 00:05:20.040
a human.

91
00:05:19.759 --> 00:05:23.600
Air, and what they've found is remarkable. These aren't just

92
00:05:23.839 --> 00:05:29.199
historical curiosities. The star positions hipparcs recorded are incredibly accurate

93
00:05:29.240 --> 00:05:33.600
for naked eye observations. As Giesenberg said, the coordinates they're

94
00:05:33.639 --> 00:05:37.319
finding are incredibly accurate for something done with the naked eye.

95
00:05:37.759 --> 00:05:41.199
This gives us a window into how ancient people understood

96
00:05:41.199 --> 00:05:42.360
and mapped the night sky.

97
00:05:42.920 --> 00:05:46.800
It's also a testament to early scientific thinking. Hiparkis was

98
00:05:46.839 --> 00:05:50.279
working without any optical instruments yet he was able to

99
00:05:50.319 --> 00:05:55.240
create precise astronomical measurements that laid the foundation for future astronomers.

100
00:05:55.639 --> 00:05:58.920
This discovery, published in the Journal for the History of Astronomy,

101
00:05:59.120 --> 00:06:03.319
helps us answer fundamental questions about the birth of science itself.

102
00:06:03.399 --> 00:06:06.279
And the manuscript, now held at the Museum of the

103
00:06:06.319 --> 00:06:09.839
Bible in Washington, d C. Is so delicate it had

104
00:06:09.879 --> 00:06:13.519
to be hand carried in climate controlled boxes to the laboratory.

105
00:06:13.959 --> 00:06:17.319
It's wonderful that modern technology can help us recover these

106
00:06:17.399 --> 00:06:22.079
ancient insights. Speaking of technology and new vantage points, let's

107
00:06:22.079 --> 00:06:24.319
turn to China's upcoming solar mission.

108
00:06:24.920 --> 00:06:28.759
China is making major strides in solar exploration with plans

109
00:06:28.800 --> 00:06:31.600
to launch its first ever solar probe to the Sun

110
00:06:31.639 --> 00:06:35.600
Earth L five point. The satellite, called Shihi Too, is

111
00:06:35.600 --> 00:06:39.000
scheduled to launch between twenty twenty eight and twenty twenty nine,

112
00:06:39.439 --> 00:06:42.800
and it will provide a unique perspective on solar activity

113
00:06:42.839 --> 00:06:44.360
that we've never had before.

114
00:06:44.920 --> 00:06:47.839
For our listeners who might not be familiar, the L

115
00:06:47.920 --> 00:06:51.240
five point or lagrange point five is one of five

116
00:06:51.319 --> 00:06:54.920
special locations in space where the gravitational forces of the

117
00:06:55.000 --> 00:06:58.120
Earth and Sun balance out. It's about one hundred and

118
00:06:58.120 --> 00:07:02.560
fifty million kilometers from Earth, and spacecraft positioned there require

119
00:07:02.680 --> 00:07:05.639
minimal fuel to maintain their orbit because they're in a

120
00:07:05.680 --> 00:07:08.759
stable gravitational equilibrium exactly.

121
00:07:08.800 --> 00:07:12.519
Anna and L five provides a direct, unobstructed view of

122
00:07:12.560 --> 00:07:15.879
the Sun without Earth's atmosphere getting in the way. This

123
00:07:15.959 --> 00:07:20.879
makes it ideal for capturing detailed data on solar magnetic fields, flares,

124
00:07:20.920 --> 00:07:24.639
and eruptions. GH two will be the first artificial probe

125
00:07:24.759 --> 00:07:26.319
ever stationed at this location.

126
00:07:26.959 --> 00:07:31.120
The mission has some impressive capabilities. GH two is equipped

127
00:07:31.120 --> 00:07:35.800
with cutting edge technology designed for high precision magnetic field detection.

128
00:07:36.279 --> 00:07:39.920
This will help reveal the intricate dynamics of solar eruptions.

129
00:07:40.240 --> 00:07:43.800
But here's what's really exciting. The mission aims to predict

130
00:07:43.879 --> 00:07:46.680
solar activity up to five days in advance.

131
00:07:47.279 --> 00:07:51.240
That's a game changer for space weather forecasting. Solar flares

132
00:07:51.240 --> 00:07:54.879
and coronal mass ejections can have profound effects on Earth's

133
00:07:54.879 --> 00:07:59.319
magnetic field and satellite systems. We've seen how geomagnetic storms

134
00:07:59.319 --> 00:08:03.600
can disrupt unication networks, GPS systems, and even power grids.

135
00:08:04.079 --> 00:08:07.959
Having five days advance warning could help protect critical infrastructure.

136
00:08:08.399 --> 00:08:12.240
It's worth noting this builds on China's previous solar mission.

137
00:08:12.639 --> 00:08:16.199
In twenty twenty one, China launched shei He, their first

138
00:08:16.240 --> 00:08:21.199
solar exploration satellite, which captured solar H alpha spectral imaging

139
00:08:21.279 --> 00:08:25.360
from low Earth orbit. GH two represents a much more

140
00:08:25.439 --> 00:08:29.160
ambitious leap, heading to a distant and challenging location.

141
00:08:29.839 --> 00:08:33.679
The mission is a collaborative effort between Nanjing University, the

142
00:08:33.840 --> 00:08:39.799
China Meteorological Administration, and the Shanghai Academy of Spaceflight Technology.

143
00:08:39.840 --> 00:08:44.200
It really demonstrates China's growing leadership in space exploration and

144
00:08:44.240 --> 00:08:48.279
their commitment to understanding space weather, and as.

145
00:08:48.080 --> 00:08:53.080
We become increasingly reliant on space based technologies, understanding and

146
00:08:53.159 --> 00:08:57.519
predicting solar activity becomes more crucial than ever. This mission

147
00:08:57.559 --> 00:09:02.320
could significantly improve our ability to protect satellites, astronauts, and

148
00:09:02.480 --> 00:09:06.080
infrastructure on Earth. Now, let's turn to a mystery that

149
00:09:06.120 --> 00:09:08.360
had astronomers scratching their heads.

150
00:09:08.759 --> 00:09:12.440
Here's a stellar detective story for you. Astronomers thought they

151
00:09:12.440 --> 00:09:17.759
were watching a massive star called WOHG sixty four undergo

152
00:09:17.840 --> 00:09:22.039
its death throws, possibly even transforming into a rare yellow

153
00:09:22.159 --> 00:09:27.080
hypergiant before going super nova. Turns out they were completely wrong.

154
00:09:27.559 --> 00:09:30.440
This is such a great example of how science works.

155
00:09:30.440 --> 00:09:35.399
Avery WHG sixty four is located in the large Magellanic

156
00:09:35.399 --> 00:09:38.440
Cloud and is one of the most luminous dust and

157
00:09:38.559 --> 00:09:43.200
shrouded red supergiants in its galaxy. In recent years, astronomers

158
00:09:43.200 --> 00:09:47.919
observed unusual dimming and changing spectral features that suggested the

159
00:09:47.919 --> 00:09:51.639
star was entering an extremely rare and unstable phase.

160
00:09:52.120 --> 00:09:54.840
In twenty twenty four, the appearance of a new dust

161
00:09:54.879 --> 00:09:58.639
cloud around the star seemed to confirm that something dramatic

162
00:09:58.759 --> 00:10:02.519
was happening. Any researchers thought they were witnessing a massive

163
00:10:02.559 --> 00:10:06.039
star in its final moments, but fresh observations from a

164
00:10:06.080 --> 00:10:09.440
team led by doctor Jocko Van Luhn at Kill University

165
00:10:09.879 --> 00:10:12.639
revealed a completely different story.

166
00:10:12.679 --> 00:10:16.759
Between November twenty twenty four and December twenty twenty five,

167
00:10:17.240 --> 00:10:21.480
the team used the Southern African Large Telescope to collect

168
00:10:21.679 --> 00:10:26.240
detailed optical spectra of woe G sixty four, but they

169
00:10:26.399 --> 00:10:31.840
found contradicted all the previous assumptions. Instead of the temperature

170
00:10:31.960 --> 00:10:36.399
increase you'd expect in a yellow hypergiant, they found strong

171
00:10:36.600 --> 00:10:40.440
absorption bands from titanium oxide molecules.

172
00:10:40.679 --> 00:10:45.120
And here's why that matters. Titanium oxide molecules can't survive

173
00:10:45.240 --> 00:10:49.039
in the hotter environments of a yellow hypergiant. That meant

174
00:10:49.240 --> 00:10:54.039
woe G sixty four hadn't undergone the suspected transformation at all.

175
00:10:54.679 --> 00:10:58.039
Something else was causing all those puzzling observations.

176
00:10:58.320 --> 00:11:02.279
The answer turned out to be a companion star. Woh

177
00:11:02.440 --> 00:11:06.360
sixty four is actually part of a binary system. A smaller,

178
00:11:06.519 --> 00:11:11.320
hotter companion star orbits the red supergiant and periodically interacts

179
00:11:11.360 --> 00:11:15.639
with its extended atmosphere. As Van Luhn explained, the atmosphere

180
00:11:15.679 --> 00:11:18.320
of the red supergiant is being stretched out by the

181
00:11:18.360 --> 00:11:22.159
approach of the companion star, but it hasn't been stripped altogether.

182
00:11:22.639 --> 00:11:26.399
So nearly every major indicator that astronomers had interpreted as

183
00:11:26.440 --> 00:11:31.120
signs of impending stellar death, the fading light, the spectral shifts,

184
00:11:31.200 --> 00:11:35.080
the dust formation, was actually caused by this companion star.

185
00:11:35.639 --> 00:11:38.440
Some of the disrupted material even appears to form a

186
00:11:38.559 --> 00:11:42.480
disk around the hot companion, which contributed to those strange

187
00:11:42.480 --> 00:11:43.559
spectral emissions.

188
00:11:43.879 --> 00:11:48.519
Van Luhn described it beautifully. We're essentially witnessing a phoenix

189
00:11:48.759 --> 00:11:53.080
rising from the ashes. It's not that WOHG sixty four

190
00:11:53.279 --> 00:11:56.960
won't eventually go super nova. It will, but that event

191
00:11:57.159 --> 00:12:00.440
isn't imminent despite what all the evidence seemed to suggest.

192
00:12:01.120 --> 00:12:05.960
This discovery highlights how binary interactions can perfectly mimic the

193
00:12:06.000 --> 00:12:07.519
hallmarks of a dying star.

194
00:12:08.039 --> 00:12:11.120
It's a humbling reminder that the universe still has plenty

195
00:12:11.159 --> 00:12:14.960
of surprises for us. Careful follow up observations with attention

196
00:12:15.039 --> 00:12:20.559
to dust obscuration revealed that earlier spectral signals were misleading. Now,

197
00:12:20.679 --> 00:12:24.279
let's shift from stellar mysteries to human achievements as Time

198
00:12:24.360 --> 00:12:26.840
Magazine celebrates an historic moment.

199
00:12:26.960 --> 00:12:30.720
As NASA's Artemis two mission sits poised on launch Pad

200
00:12:30.879 --> 00:12:34.600
thirty nine B at Kennedy Space Center, Time Magazine has

201
00:12:34.679 --> 00:12:37.919
honored the crew with a special commemorative cover issue that

202
00:12:38.039 --> 00:12:42.840
draws powerful parallels to one of history's most pivotal space missions.

203
00:12:43.440 --> 00:12:47.480
The cover features the four Artemis two astronauts Read Wiseman,

204
00:12:47.799 --> 00:12:52.240
Jeremy Hansen, Victor Glover, and Christina Koch, who are scheduled

205
00:12:52.240 --> 00:12:55.080
to launch as early as February eighth for a ten

206
00:12:55.159 --> 00:12:59.080
day lunar flyby mission. The article accompanying it was written

207
00:12:59.120 --> 00:13:02.360
by Jeffrey Kluk, the best selling author known for Apollo

208
00:13:02.440 --> 00:13:04.519
thirteen and the Apollo Murders.

209
00:13:04.879 --> 00:13:09.279
What's particularly poignant is the comparison, Kluger draws to Apollo eight,

210
00:13:09.720 --> 00:13:13.279
which orbited the Moon in December nineteen sixty eight. That

211
00:13:13.519 --> 00:13:16.519
was a year of tremendous turmoil in the United States

212
00:13:16.559 --> 00:13:20.159
and around the world, and Apollo eight's Christmas Eve broadcast

213
00:13:20.200 --> 00:13:23.919
from lunar orbit provided a moment of unity and inspiration

214
00:13:24.360 --> 00:13:26.639
that transcended borders and politics.

215
00:13:27.320 --> 00:13:30.639
As Kluger writes in the article, not every mission touches

216
00:13:30.720 --> 00:13:35.559
the collective soul, but some do. Apollo eight, Apollo eleven,

217
00:13:36.000 --> 00:13:41.320
Apollo thirteen. These were less American experiences than global dramas,

218
00:13:41.639 --> 00:13:46.600
global triumphs, global joys, and he suggests Artemis two could

219
00:13:46.600 --> 00:13:47.960
work similar magic today.

220
00:13:48.559 --> 00:13:52.240
The mission itself will push human spaceflight to new limits.

221
00:13:52.720 --> 00:13:56.159
Artemis two's trajectory will take the crew four thousand, seven

222
00:13:56.320 --> 00:13:59.720
hundred miles beyond the far side of the Moon, farther

223
00:13:59.759 --> 00:14:02.799
than our species has ever traveled. That will break the

224
00:14:02.879 --> 00:14:05.720
old record of one hundred and fifty eight miles past

225
00:14:05.759 --> 00:14:08.879
the Moon, which was held by the Apollo thirteen astronauts

226
00:14:08.960 --> 00:14:11.279
during that dramatic nineteen seventy mission.

227
00:14:11.960 --> 00:14:16.360
NASA Administrator Jared Izikman posted side by side Time magazine

228
00:14:16.360 --> 00:14:19.279
covers from nineteen sixty eight and twenty twenty six on

229
00:14:19.320 --> 00:14:23.159
social media, noting that fifty eight years after Apollo eight's

230
00:14:23.240 --> 00:14:27.360
historic trip, NASA is heading back. He emphasized that through

231
00:14:27.399 --> 00:14:31.360
the Artemis campaign, the agency aims to maintain American leadership

232
00:14:31.399 --> 00:14:35.039
in space, land astronauts on the Moon, and establish a

233
00:14:35.120 --> 00:14:37.879
lunar base, all before the end of twenty twenty eight.

234
00:14:38.559 --> 00:14:41.879
What strikes me about both Apollo eight and Artemis two

235
00:14:42.399 --> 00:14:46.120
is their role in opening new chapters. Apollo eight proved

236
00:14:46.240 --> 00:14:49.960
humans could safely journey to the Moon and return, paving

237
00:14:50.000 --> 00:14:53.720
the way for Apollo eleven it's landing. Artemis two is

238
00:14:53.759 --> 00:14:57.840
similarly demonstrating the capabilities that will enable Artemis three to

239
00:14:57.879 --> 00:15:00.320
put humans back on the lunar surface.

240
00:15:00.600 --> 00:15:03.799
And, as Kluger points out, the mission represents not just

241
00:15:03.840 --> 00:15:07.759
the technological achievement, but a significant edge in any space

242
00:15:07.840 --> 00:15:11.080
race with China, while also offering the kind of public

243
00:15:11.200 --> 00:15:14.360
uplift that spaceflight has uniquely been able to provide since

244
00:15:14.399 --> 00:15:18.000
the nineteen sixties. It's a moment when four people serve

245
00:15:18.039 --> 00:15:20.960
as emissaries for the a point three billion of us

246
00:15:21.000 --> 00:15:22.120
who remain earthbound.

247
00:15:22.759 --> 00:15:25.960
With the Wet Dress rehearsal happening right now and launched

248
00:15:26.000 --> 00:15:30.039
potentially just days away. This Time Magazine issue captures what

249
00:15:30.120 --> 00:15:33.519
could be one of twenty twenty six's most inspiring moments.

250
00:15:34.080 --> 00:15:37.600
And speaking of inspiration, we need to remember someone who

251
00:15:37.639 --> 00:15:41.480
made a profound but often overlooked contribution to how we

252
00:15:41.600 --> 00:15:42.600
navigate our world.

253
00:15:43.279 --> 00:15:46.840
We're closing today's show with a remembrance of doctor Gladys West,

254
00:15:46.919 --> 00:15:49.559
who passed away Saturday at the age of ninety five.

255
00:15:50.279 --> 00:15:53.519
West was one of the hidden figures whose work fundamentally

256
00:15:53.559 --> 00:15:58.679
shaped modern GPS technology, yet her contributions went largely unrecognized

257
00:15:58.759 --> 00:15:59.519
until recently.

258
00:16:00.120 --> 00:16:04.639
Gladys West's story is one of extraordinary perseverance and achievement

259
00:16:04.720 --> 00:16:08.080
in the face of significant obstacles. She was born on

260
00:16:08.120 --> 00:16:12.759
October twenty seventh, nineteen thirty in rural Sutherland, Virginia, south

261
00:16:12.799 --> 00:16:15.799
of Richmond. Her parents had a small farm, and most

262
00:16:15.879 --> 00:16:19.759
of the region's population were tenant farmers known as sharecroppers.

263
00:16:20.440 --> 00:16:23.399
She initially expected her future would lead to farm work

264
00:16:23.480 --> 00:16:25.879
or a job at the tobacco processing plant where her

265
00:16:25.879 --> 00:16:30.039
mother worked, but she excelled academically, becoming valedictorian of her

266
00:16:30.080 --> 00:16:33.519
high school graduating class. She earned a full scholarship to

267
00:16:33.639 --> 00:16:37.559
Virginia State College, which was a historically black institution, and

268
00:16:37.639 --> 00:16:40.480
went on to earn both her bachelor's and master's degrees

269
00:16:40.480 --> 00:16:41.279
in mathematics.

270
00:16:41.879 --> 00:16:45.480
This was during the Jim Crow era of racial segregation avery.

271
00:16:45.879 --> 00:16:49.440
After graduating in nineteen fifty five, the same year President

272
00:16:49.480 --> 00:16:54.240
Eisenhower banned racial discrimination in federal hiring, West began working

273
00:16:54.279 --> 00:16:57.840
at what was then called the Naval Proving Ground in Dahlgren, Virginia.

274
00:16:58.320 --> 00:17:01.519
She told NPR that there were three other black professionals there,

275
00:17:01.879 --> 00:17:04.759
and they tried to treat the leaders with respect while

276
00:17:04.799 --> 00:17:06.759
hoping for the same treatment in return.

277
00:17:07.319 --> 00:17:10.599
West stayed at Dahlgren for forty two years, and her

278
00:17:10.640 --> 00:17:15.279
contributions were remarkable. In the nineteen sixties, she participated in

279
00:17:15.319 --> 00:17:19.680
a study showing that Pluto's motion is regular compared with Neptune.

280
00:17:20.240 --> 00:17:23.480
But her most significant work came in the nineteen seventies

281
00:17:23.519 --> 00:17:28.319
and eighties, when she helped develop the foundational mathematics for GPS.

282
00:17:29.000 --> 00:17:32.920
What's fascinating is the complexity of what she accomplished. West

283
00:17:33.000 --> 00:17:37.000
used in triked algorithms to account for variations in gravitational

284
00:17:37.160 --> 00:17:41.240
title and other forces that distort Earth's shape. She programmed

285
00:17:41.279 --> 00:17:45.240
the IBM's seventy thirty computer, also known as Stretch, to

286
00:17:45.319 --> 00:17:49.880
deliver increasingly refined calculations for an extremely accurate model of

287
00:17:49.920 --> 00:17:53.920
Earth shape, specifically optimized for what ultimately became the GPS

288
00:17:54.079 --> 00:17:56.119
orbit used by satellite.

289
00:17:56.200 --> 00:18:00.680
Her work essentially created the mathematical framework that allows GPS

290
00:18:00.720 --> 00:18:05.400
to function accurately. Today, there are about four billion GPS

291
00:18:05.519 --> 00:18:09.720
users worldwide, according to Lockheed Martin. Yet, when asked about

292
00:18:09.839 --> 00:18:14.000
using GPS herself, West told an NPR affiliate in twenty

293
00:18:14.039 --> 00:18:17.000
twenty that she used it on a minimal basis, she

294
00:18:17.119 --> 00:18:17.839
preferred maps.

295
00:18:18.440 --> 00:18:22.440
West's career wasn't widely recognized until the twenty sixteen publication

296
00:18:22.640 --> 00:18:26.359
of Margot Lee Shutterley's book Hidden Figures and the Hollywood

297
00:18:26.359 --> 00:18:29.759
film based on it. After that, the accolades came quickly.

298
00:18:30.160 --> 00:18:32.720
She was inducted into the Air Force, Space and Missile

299
00:18:32.720 --> 00:18:35.799
Pioneers Hall of Fame in twenty eighteen, received the Webby

300
00:18:35.920 --> 00:18:39.200
Lifetime Achievement Award in twenty twenty one, and was honored

301
00:18:39.200 --> 00:18:42.119
with the Prince Philip Medal by the UK's Royal Academy

302
00:18:42.119 --> 00:18:42.839
of Engineering.

303
00:18:43.519 --> 00:18:46.640
She was predecessed last year by her husband of fifty

304
00:18:46.680 --> 00:18:50.160
seven years, Ira, whom she met at the Naval proving Ground.

305
00:18:50.640 --> 00:18:54.599
The couple had three children and seven grandchildren. Her family

306
00:18:54.640 --> 00:18:57.640
announced that she passed peacefully alongside loved ones.

307
00:18:58.160 --> 00:19:01.160
Blattys West's story reminds us that some of the most

308
00:19:01.200 --> 00:19:05.920
important scientific contributions come from unexpected places and from people

309
00:19:05.960 --> 00:19:10.119
who had to overcome tremendous barriers. From a childhood in Borough,

310
00:19:10.200 --> 00:19:14.839
Virginia during segregation, to reshaping how the entire world navigates.

311
00:19:15.200 --> 00:19:18.599
Her legacy touches billions of lives every single day.

312
00:19:19.160 --> 00:19:23.359
Every time someone uses GPS to find directions, track a delivery,

313
00:19:23.759 --> 00:19:27.160
or navigate by sea or air, they're benefiting from the

314
00:19:27.200 --> 00:19:32.480
mathematical foundations Gladys West helped establish. It's a powerful reminder

315
00:19:32.519 --> 00:19:35.839
that science is built by people from all backgrounds, and

316
00:19:35.880 --> 00:19:39.119
that we should celebrate those contributions while the pioneers are

317
00:19:39.160 --> 00:19:39.920
still with us.

318
00:19:40.480 --> 00:19:44.119
And that wraps up today's episode of Astronomy Daily. We've

319
00:19:44.200 --> 00:19:48.720
journeyed from SpaceX's ambitious satellite plans to ancient star maps

320
00:19:48.960 --> 00:19:52.680
from solar observatories at special points in space, to stellar

321
00:19:52.720 --> 00:19:56.240
mysteries solved from upcoming lunar missions, to the legacy of

322
00:19:56.279 --> 00:19:57.559
a GPS pioneer.

323
00:19:58.200 --> 00:20:00.799
It's been quite a tour through the cost that's mos Anna.
