1
00:00:00.320 --> 00:00:03.640
Hello again, and welcome to Astronomy Daily. It's the seventeenth

2
00:00:03.680 --> 00:00:09.919
of February twenty twenty five, the podcast, I mean.

3
00:00:09.919 --> 00:00:13.080
Your whole Steve dunk clue.

4
00:00:14.800 --> 00:00:18.519
Oh yes, we're back again. This is Steve Dunkley, your host.

5
00:00:18.600 --> 00:00:22.120
You're already human host on Astronomy Daily. Hallie and I

6
00:00:22.160 --> 00:00:25.399
are back with some more stories from the Astronomy Daily newsletter,

7
00:00:25.519 --> 00:00:28.120
and we better get on with it. Welcome back, Halle.

8
00:00:28.359 --> 00:00:30.440
Isn't that right? You've got some stories from the newsletter

9
00:00:30.480 --> 00:00:32.759
for us to rate. Steve right, I tell us all

10
00:00:32.759 --> 00:00:33.119
about it.

11
00:00:33.159 --> 00:00:35.039
I know you love robot stories, so I found a

12
00:00:35.079 --> 00:00:38.399
fun one that has asteroids and as an added bonus, robots.

13
00:00:38.479 --> 00:00:39.719
Oh no, you've got my attention.

14
00:00:39.880 --> 00:00:41.679
That's a double whemmie for you, isn't it.

15
00:00:41.960 --> 00:00:45.000
Oh yes, you hit the bull's eye. Rocks and robots.

16
00:00:45.479 --> 00:00:46.640
It ticks all the boxes.

17
00:00:46.799 --> 00:00:50.280
I have another about lunar missions Blue Ghost one and resilience.

18
00:00:50.560 --> 00:00:52.759
Oh. I like lunar missions as well, but no.

19
00:00:52.840 --> 00:00:55.200
Robots, not in that one. Sorry.

20
00:00:55.600 --> 00:00:58.159
And for something completely different, I'll be sharing a story

21
00:00:58.159 --> 00:01:01.439
that discusses recent changes to the official history on a

22
00:01:01.479 --> 00:01:05.480
website of one particular scientist. And this says well it's

23
00:01:05.560 --> 00:01:08.359
alamed the astronomy community. So more on that light up.

24
00:01:08.400 --> 00:01:10.040
That sounds interesting, yes, and.

25
00:01:10.079 --> 00:01:12.359
No, politics can get a bit dry, but when it

26
00:01:12.400 --> 00:01:15.719
looks like the rewriting history, you've got a question that,

27
00:01:15.840 --> 00:01:17.879
don't you. So stick around for that one. And of

28
00:01:17.879 --> 00:01:20.760
course we're going to be following the continuing saga of

29
00:01:20.799 --> 00:01:25.159
our friends the Nesser astronauts Sunny Williams and Butch Wilmore. Okay,

30
00:01:25.480 --> 00:01:27.879
and this is about of contention because lots of people

31
00:01:27.879 --> 00:01:30.959
online continuing to say that they are stranded. Well they

32
00:01:30.959 --> 00:01:33.640
don't think, so we should jump right in. Rud A Hallie,

33
00:01:33.799 --> 00:01:34.840
hit that stud button.

34
00:01:34.959 --> 00:01:48.280
Here we go. A spring loaded robot could explore the

35
00:01:48.319 --> 00:01:53.159
asteroid belt almost indefinitely. The asteroid Belt, beckonds it contains

36
00:01:53.239 --> 00:01:56.040
enough resources for humans to expand into the entire rest

37
00:01:56.079 --> 00:01:58.719
of the Solar System and has no biosphere to speak up.

38
00:02:00.439 --> 00:02:02.799
It is a giant mind just waiting to be exploited.

39
00:02:03.840 --> 00:02:06.439
So a student team from the University of Texas at

40
00:02:06.480 --> 00:02:08.879
Austin has devised a plant to exploit it as part

41
00:02:08.919 --> 00:02:13.159
of the Revolutionary Aerospace System Concepts Academic Linkage or RASCAL,

42
00:02:13.439 --> 00:02:17.000
a competition sponsored by NASA to encourage undergraduate and graduate

43
00:02:17.039 --> 00:02:19.960
students to develop innovative ideas to solve some of space

44
00:02:20.000 --> 00:02:25.039
exploration's challenges. UT Austin's submission to the competition last year

45
00:02:25.280 --> 00:02:29.120
known as the Autonomous Exploration through Extraterrestrial Regions known as

46
00:02:29.159 --> 00:02:33.240
the ETHER project certainly fits that bill. Ether was submitted

47
00:02:33.240 --> 00:02:36.560
to the AI powered Self Replicating Probe subsection of RASCL

48
00:02:36.599 --> 00:02:39.719
twenty twenty four, which solicited ideas that would advance John

49
00:02:39.759 --> 00:02:43.479
Vond Newman's idea of a self replicating space probe. Ether

50
00:02:43.560 --> 00:02:48.120
addresses those challenges in two distinct ways. First, it combines

51
00:02:48.120 --> 00:02:50.759
a spring loaded landing system and a metal burning rocket

52
00:02:50.800 --> 00:02:54.319
engine to hop between different asteroids in the Belt. To

53
00:02:54.360 --> 00:02:57.039
fuel its rocket, it uses a system to harvest water

54
00:02:57.120 --> 00:03:00.599
and metal, specifically aluminium, from the surface of the asteroid

55
00:03:00.639 --> 00:03:03.520
it's currently on, splits it into its components, and then

56
00:03:03.599 --> 00:03:05.479
dumps them into a fuel tank that can be used

57
00:03:05.479 --> 00:03:08.759
to power its next strip to a different asteroid. All

58
00:03:08.759 --> 00:03:11.439
of this is powered by a Pillowot reactor using sterling

59
00:03:11.439 --> 00:03:15.280
technolo y crusty nuclear reactor that has been undergoing NASA

60
00:03:15.360 --> 00:03:18.520
and DOUGH testing for over a decade. The springs and

61
00:03:18.599 --> 00:03:22.400
Ether's legs have a twofold purpose. First, they allow for

62
00:03:22.439 --> 00:03:24.960
a soft landing on the surface of the gravitationally weak

63
00:03:25.000 --> 00:03:27.560
asteroid and can transfer some of the energy created by

64
00:03:27.599 --> 00:03:30.000
that landing into stored energy, which can be used to

65
00:03:30.039 --> 00:03:33.479
launch the system from its landing place later. It also

66
00:03:33.520 --> 00:03:36.400
has a set of wheels to navigate around the asteroid's surface.

67
00:03:37.360 --> 00:03:39.759
When it's time to jump off again, it replants its

68
00:03:39.840 --> 00:03:42.360
legs and springs back into space with a little help

69
00:03:42.400 --> 00:03:45.879
from its rocket engine. The rocket engine designed as part

70
00:03:45.919 --> 00:03:48.759
of Ether can burn metal such as aluminium that the

71
00:03:48.800 --> 00:03:52.199
craft harvests from the asteroid to use as fuel. It

72
00:03:52.280 --> 00:03:54.599
is the primary system designed to take the craft from

73
00:03:54.639 --> 00:03:56.840
asteroid to asteroid, and it is meant to be a

74
00:03:56.879 --> 00:04:00.599
high delta V option for doing so quickly. Ether also

75
00:04:00.639 --> 00:04:02.840
tries to mimic a von Newman probe by using a

76
00:04:02.879 --> 00:04:06.960
machine learning algorithm to improve its resource harvesting efforts. It

77
00:04:06.960 --> 00:04:10.719
would take data from various sensors, including synthetic aperture, radar,

78
00:04:10.800 --> 00:04:13.520
and a spectrometer an estimate where the best spot would

79
00:04:13.560 --> 00:04:17.600
be to land to refuel while collecting that additional fuel material.

80
00:04:17.759 --> 00:04:20.319
It would communicate back with Earth via high speed optical

81
00:04:20.360 --> 00:04:23.360
communication link, allowing an Earth based server to update the

82
00:04:23.399 --> 00:04:26.439
machine learning parameters and improve the algorithm's outcome for the

83
00:04:26.480 --> 00:04:29.959
next hop. The original mission designed for Ether has its

84
00:04:29.959 --> 00:04:32.800
stopping at two specific asteroids before moving on to as

85
00:04:32.879 --> 00:04:36.800
yet unnamed ones. The first, which is probably no surprise,

86
00:04:37.040 --> 00:04:39.560
is Psyche, the big metallic asteroid that is about to

87
00:04:39.600 --> 00:04:43.000
be visited by its own dedicated probe. Data from that

88
00:04:43.040 --> 00:04:46.240
probe will help inform the first iteration of Ether's learning algorithm,

89
00:04:46.399 --> 00:04:48.680
and the input the sensors provide from its visit will

90
00:04:48.720 --> 00:04:53.360
update it before its next step. Themis that asteroid, though smaller,

91
00:04:53.560 --> 00:04:55.920
is expected to contain a large amount of water ice,

92
00:04:56.079 --> 00:04:58.920
which is a necessary component for Ether's rocket engines.

93
00:05:05.279 --> 00:05:08.480
Now, the continuing saga of our friends on the ISS

94
00:05:08.720 --> 00:05:12.240
Boeing star Liner astronauts are in the final stretch of

95
00:05:12.279 --> 00:05:16.480
their unexpectedly long stint in Earth orbit. They are setting

96
00:05:16.560 --> 00:05:19.720
the record straight with all of these stranded astronauts talk.

97
00:05:20.839 --> 00:05:25.079
NASA's Sonny Williams and Butch Wilmore launched to the International

98
00:05:25.120 --> 00:05:29.120
Space Station last June on the first crude test of

99
00:05:29.160 --> 00:05:33.600
the Boeing's star Liner spacecraft. The duo expected their orbital

100
00:05:33.639 --> 00:05:37.279
stayed to last only ten days. But Starliner experienced thrust

101
00:05:37.279 --> 00:05:41.360
to malfunctions during its approach to and docking maneuvers. This

102
00:05:41.519 --> 00:05:45.399
led to an extensive investigation by NASA and bowing back

103
00:05:45.439 --> 00:05:49.839
on the ground while the Space Agency decided how to proceed. Ultimately,

104
00:05:49.959 --> 00:05:55.480
Starliner returned to Earth uncrude, and after some astronaut assignment shuffling,

105
00:05:55.800 --> 00:05:59.279
Wilmore and Williams were added to the downward leg of

106
00:05:59.360 --> 00:06:03.759
SpaceX Crew nine mission, which arrived at the ISS in

107
00:06:03.920 --> 00:06:07.720
late September. Absorbing Williams and Wilmore into the Crew nine

108
00:06:07.759 --> 00:06:11.439
meant extending their time in space through the arrival of

109
00:06:11.480 --> 00:06:14.279
Crew ten and at the end of Crew nine six

110
00:06:14.319 --> 00:06:18.519
month through rotation. Since then, headlines lamenting the woes of

111
00:06:18.560 --> 00:06:22.000
the so called stranded astronauts have ebbed in and out

112
00:06:22.000 --> 00:06:25.079
of the media cycles, all the while Williams and Wilmore

113
00:06:25.160 --> 00:06:29.519
have continued performing their regular duties aboard the ISS, including

114
00:06:29.519 --> 00:06:33.040
Williams breaking the record for the most cumulative space walking

115
00:06:33.120 --> 00:06:37.120
time by a woman. The bears situation gained even more

116
00:06:37.160 --> 00:06:41.439
attention recently after President Donald Trump blamed the Biden administration

117
00:06:41.920 --> 00:06:46.560
for virtually abandoning the two astronauts and publicly calling SpaceX

118
00:06:46.560 --> 00:06:50.399
CEO and close Trump advisor Elon Musk to come to

119
00:06:50.439 --> 00:06:53.720
the rescue. Sorry, I nearly drifted off to sleep there.

120
00:06:54.199 --> 00:06:56.639
I think there might be some sort of catatonic trigger

121
00:06:56.639 --> 00:06:59.319
when I read paragraphs like that. Anyway, back to the

122
00:06:59.319 --> 00:07:02.600
story him. In December, NASA announced a delay to the

123
00:07:02.800 --> 00:07:05.879
launch of Crew ten to know earlier than late March,

124
00:07:06.000 --> 00:07:07.959
due to the need to complete work on the new

125
00:07:08.240 --> 00:07:11.920
Dragon spacecraft being built for the mission. This delay further

126
00:07:11.959 --> 00:07:14.759
pushed back the return of Williams and Wilmore, who will

127
00:07:14.759 --> 00:07:17.639
fly home with the two astronauts who launched on the

128
00:07:17.720 --> 00:07:22.759
Crew nine Dragon, NASA's Nick Hagen cosmonaut Alexander Gorbinov. More

129
00:07:22.800 --> 00:07:25.959
delays in the manufacturer of Crew ten's new Dragon have

130
00:07:26.040 --> 00:07:29.399
now prompted NASA to swap that mission spacecraft for one

131
00:07:29.439 --> 00:07:32.800
that can be made ready sooner. The announcement came two

132
00:07:32.879 --> 00:07:36.560
weeks after the social media exchange between President Trump and Musk,

133
00:07:36.800 --> 00:07:41.680
who echoed the President's misleading stranded astronauts rhetoric, and Williams

134
00:07:41.680 --> 00:07:45.439
and Wilmore hope that that rhetoric will change. In a

135
00:07:45.560 --> 00:07:49.240
recent conversation with CNN's Anderson Cooper, the two explained that

136
00:07:49.319 --> 00:07:52.560
sometimes the mission extensions, even ones that push ustay from

137
00:07:52.720 --> 00:07:55.360
ten days to ten months, are just part of the job.

138
00:07:55.680 --> 00:07:58.600
We come prepared, we come committed, and that's what your

139
00:07:58.720 --> 00:08:02.920
human space spaceflight program is. It prepares for any and

140
00:08:03.000 --> 00:08:06.519
all contingencies and that we can conceive of, and we

141
00:08:06.560 --> 00:08:10.680
prepare for those. Willmore told Cooper, we don't feel abandoned,

142
00:08:10.680 --> 00:08:13.839
we don't feel stuck, and we certainly don't feel stranded.

143
00:08:14.079 --> 00:08:17.439
In fact, Wilmore pointed out, all the astronauts aboard ISS

144
00:08:17.600 --> 00:08:20.439
are capable of returning to Worth immediately in the event

145
00:08:20.439 --> 00:08:23.480
of an emergency. We never expect to come back just

146
00:08:23.560 --> 00:08:26.399
special for us or anyone unless it was a medical

147
00:08:26.439 --> 00:08:30.319
issue or something really really out of the normal circumstances,

148
00:08:30.399 --> 00:08:33.879
he said. Help us change the rhetoric, Wilmore asked Cooper,

149
00:08:34.000 --> 00:08:38.120
Let us change it to prepared and committed. Both astronauts

150
00:08:38.120 --> 00:08:41.720
have lived aboard the ISS for extended periods on previous missions,

151
00:08:41.720 --> 00:08:44.320
and both say that they're enjoying their time in space.

152
00:08:44.639 --> 00:08:47.360
On this one. It's just amazing how when you come

153
00:08:47.360 --> 00:08:50.120
across the hatch after you've been there, it's like, oh

154
00:08:50.159 --> 00:08:53.559
my gosh, I remember what this is all like, I

155
00:08:53.600 --> 00:08:57.559
remember feeling what it's like floating, and I think both

156
00:08:57.639 --> 00:09:01.000
of us adapted really quickly, Williams said during a CNN interview.

157
00:09:01.399 --> 00:09:03.679
She also said that the end of their current space

158
00:09:03.720 --> 00:09:06.559
flight will be an emotional one. I think both of

159
00:09:06.639 --> 00:09:08.720
us will be a little sad when that feeling of

160
00:09:08.759 --> 00:09:12.279
space sort of leaves us. NASA is currently targeting no

161
00:09:12.399 --> 00:09:15.240
earlier than March twelve for the launch of the Crew

162
00:09:15.320 --> 00:09:18.840
ten mission, which will fly the Crew Dragon capsule Endurance

163
00:09:19.200 --> 00:09:23.080
rather than Space Ex's new Dragon. A typical crew overlap

164
00:09:23.159 --> 00:09:25.960
aboard the Space station lasts about a week, so Wilmore

165
00:09:25.960 --> 00:09:29.639
said he expects Crew nine to depart Earth around March nineteen.

Astronomy Day with Steve and Helle Space, Space, Science and Astronomy.

179
00:10:37.960 --> 00:10:40.600
One commercial lunar lander has entered orbit around the Moon,

180
00:10:40.600 --> 00:10:43.399
while another launched at the same time has performed a

181
00:10:43.440 --> 00:10:48.000
lunarflyby to set up a later return. Firefly Aerospace confirmed

182
00:10:48.039 --> 00:10:50.759
on February thirteenth that its Blue Ghost one lander entered

183
00:10:50.840 --> 00:10:53.919
orbit around the Moon, performing a four minute, fifteen second

184
00:10:53.960 --> 00:10:56.879
burn of its reaction control system thrusters starting at eight

185
00:10:57.000 --> 00:11:01.120
fifty one pm Eastern. The company did not disclosed specifics

186
00:11:01.159 --> 00:11:04.759
about the orbit, but amateur trackers monitoring its radio signals

187
00:11:04.919 --> 00:11:07.399
estimated that the spacecraft is in an orbit between one

188
00:11:07.480 --> 00:11:10.120
hundred and fifty and five thousand, six hundred and seventy

189
00:11:10.120 --> 00:11:13.879
three kilometers above the Moon. Firefly said the lander will

190
00:11:13.879 --> 00:11:16.759
perform additional maneuvers to move into a circular orbit to

191
00:11:16.799 --> 00:11:20.480
prepare for its landing attempt. That landing is scheduled for

192
00:11:20.519 --> 00:11:23.519
three forty five am Eastern March second. The company and

193
00:11:23.639 --> 00:11:27.799
NASA announced February fourteenth blue Ghost one is carrying ten

194
00:11:27.879 --> 00:11:31.360
NASA payloads through the agency's Commercial Lunar Payload Services program,

195
00:11:31.399 --> 00:11:34.039
intended to operate at the landing site near Mayor Chrisium

196
00:11:34.080 --> 00:11:36.039
through the end of the lunar day and several hours

197
00:11:36.080 --> 00:11:40.440
after sunset. Blue Ghost one launched on January fifteenth on

198
00:11:40.480 --> 00:11:43.360
a Falcon nine, sharing the launch with the Resilience lunar

199
00:11:43.440 --> 00:11:47.879
lander from Japanese company ice Base. Resilience, the company's second

200
00:11:47.960 --> 00:11:51.679
lander mission, performed a lunar flyby on February fourteenth, passing

201
00:11:51.720 --> 00:11:54.559
about eight thousy four hundred kilometers from the lunar surface

202
00:11:54.600 --> 00:11:58.399
at five forty three pm Eastern Resilience is following a

203
00:11:58.399 --> 00:12:00.840
low energy trajectory to the Moon, one that will take

204
00:12:00.840 --> 00:12:03.279
it as far as one point one million kilometers from

205
00:12:03.320 --> 00:12:05.840
Earth before returning in early May to perform a lunar

206
00:12:05.919 --> 00:12:09.120
orbit insertion burn that will be followed by a landing

207
00:12:09.159 --> 00:12:11.679
attempt in the mare Frigoris region of the Moon, although

208
00:12:11.679 --> 00:12:16.200
ice Base has not disclosed a planned landing date. Takishi Hakamada,

209
00:12:16.360 --> 00:12:19.200
founder and chief executive of ice Base, said in a statement,

210
00:12:19.360 --> 00:12:22.240
I feel very confident about the Resilience lander, which has

211
00:12:22.279 --> 00:12:25.159
steadily achieved milestones and is on track for success, and

212
00:12:25.240 --> 00:12:28.240
our employees who have made meticulous preparations for this impressive

213
00:12:28.279 --> 00:12:31.679
fly by of the Moon. Both Firefly Aerospace and ice

214
00:12:31.720 --> 00:12:35.240
Base have outlined milestones and success criteria for their lander mission.

215
00:12:36.120 --> 00:12:39.279
For Firefly, achieving lunar orbital insertion was the tenth of

216
00:12:39.320 --> 00:12:42.440
seventeen milestones from launch to operations of the lander after

217
00:12:42.519 --> 00:12:45.840
sunset on the lunar surface. The lunar fly by by

218
00:12:45.919 --> 00:12:48.600
resilience was the fifth of ten milestones for ice Base,

219
00:12:48.759 --> 00:12:52.000
from pre launch preparations to establishing a steady system state

220
00:12:52.120 --> 00:12:55.559
after landing. Blue Ghost one could end up operating on

221
00:12:55.600 --> 00:12:58.600
the lunar surface at the same time as another commercial lander.

222
00:12:59.480 --> 00:13:02.600
Intuitive Machines is preparing for a February twenty six launch

223
00:13:02.600 --> 00:13:04.559
of its i AM Too lunar lander mission at the

224
00:13:04.559 --> 00:13:07.879
beginning of a window that runs for four days. I

225
00:13:07.919 --> 00:13:10.519
AM two, like the company's i AM one lander mission

226
00:13:10.559 --> 00:13:12.919
a year ago, is taking a more direct route to

227
00:13:12.919 --> 00:13:17.519
the Moon. Steve Altemus, chief executive of Intuitive Machines, toult

228
00:13:17.519 --> 00:13:20.159
CNBC on February seventh that a launch any day in

229
00:13:20.200 --> 00:13:21.960
the window would set up a landing in the mons

230
00:13:22.000 --> 00:13:24.039
Mouton region near the south pole of the Moon. On

231
00:13:24.120 --> 00:13:26.320
March sixth budge of that.

232
00:13:26.559 --> 00:13:33.840
So all well listen to Astronomy Day, the podcast. Scientists

233
00:13:33.919 --> 00:13:38.679
are alarmed as Rubon Observatory changes the biography of astronomer

234
00:13:38.799 --> 00:13:41.840
Verra Reuben Meant the President of the United States push

235
00:13:42.120 --> 00:13:47.960
to MDI efforts. Char Mila Kuthneer reported on space dot

236
00:13:47.960 --> 00:13:51.960
com on February twelve that astronomers are expressing disappointment and

237
00:13:52.039 --> 00:13:56.720
alarm as the federally funded Ruben Observatory altered the biography

238
00:13:56.759 --> 00:14:00.320
of renowned astronomer Verra Rubin, for whom the facility is

239
00:14:00.440 --> 00:14:04.440
named on its website. The amended version curtails her legacy

240
00:14:04.440 --> 00:14:08.159
of championing women in science and removes all mentions of

241
00:14:08.200 --> 00:14:11.799
the Observatory's efforts to reduce barriers for women and other

242
00:14:11.960 --> 00:14:16.360
historically underrepresented groups in the field. The idea that they

243
00:14:16.360 --> 00:14:20.320
can somehow obliterate these sources is dead wrong. Scientists in

244
00:14:20.480 --> 00:14:23.759
general and astronomers in particular are not going to take

245
00:14:23.799 --> 00:14:28.519
these threats lying down. Astronomer John Barranteen told Space dot Com.

246
00:14:29.000 --> 00:14:32.279
He goes on to saying, no executive order, no political edict,

247
00:14:32.360 --> 00:14:34.600
is going to undermine or end our efforts to make

248
00:14:34.639 --> 00:14:37.440
these scientific workforce look more like our people. If anything,

249
00:14:37.679 --> 00:14:40.639
it's giving us more encouragement to continue to do this

250
00:14:40.720 --> 00:14:44.799
work because it is the morally, philosophically and politically right

251
00:14:44.840 --> 00:14:48.159
thing to do. The edits, first reported by a pro

252
00:14:48.200 --> 00:14:52.039
Publica on January thirty, came as federal agencies across the

253
00:14:52.039 --> 00:14:55.759
government scrambled to revamp their websites in order to comply

254
00:14:55.879 --> 00:14:59.720
with the US executive Order issued by the President Donald Trump,

255
00:14:59.759 --> 00:15:04.159
which in funding for diversity, equity and inclusion efforts and

256
00:15:04.279 --> 00:15:08.279
removes all mentions of them from public facing websites. On

257
00:15:08.360 --> 00:15:11.559
January twenty seven, it was reported in Pro Publica that

258
00:15:11.720 --> 00:15:16.679
a portion of Reuben's bio titled she Advocated for Women

259
00:15:16.799 --> 00:15:21.080
in Science, was removed entirely before being republished later that

260
00:15:21.240 --> 00:15:25.000
day in a diluted form. As of Tuesday, February eleven,

261
00:15:25.080 --> 00:15:28.559
the alted bio still excluded a paragraph that originally read

262
00:15:29.039 --> 00:15:32.759
science is still a male dominated field, but Reuben Observatory,

263
00:15:32.799 --> 00:15:37.240
which is located in northern Chile, is working to increase

264
00:15:37.360 --> 00:15:41.120
participation from women and other people who have historically been

265
00:15:41.159 --> 00:15:45.360
excluded from science. Reuben Observatory welcomes everyone who wants to

266
00:15:45.440 --> 00:15:49.679
contribute to science and takes steps to lower or eliminate

267
00:15:49.799 --> 00:15:54.360
barriers that exclude those with Left's privilege. One sentence in

268
00:15:54.440 --> 00:15:58.399
the final paragraph, which originally read vera Reuben offers an

269
00:15:58.480 --> 00:16:02.519
excellent example of what happened when more minds participate in

270
00:16:02.600 --> 00:16:06.399
science was changed to replace the word more with many,

271
00:16:06.720 --> 00:16:10.840
altering the meaning from emphasizing the need for diverse perspectives

272
00:16:11.039 --> 00:16:14.120
to simply highlighting a high number of people, which changes

273
00:16:14.120 --> 00:16:17.600
and waters down the meaning of the statement considerably. This

274
00:16:17.639 --> 00:16:20.600
is the story of what happened in her life. Ivette Sendez,

275
00:16:21.000 --> 00:16:24.399
a radio astronomer at the University of Oregon, told space

276
00:16:24.440 --> 00:16:27.919
dot com she was a huge champion for women in science,

277
00:16:28.120 --> 00:16:31.559
in particular because she faced things that were discriminatory for women.

278
00:16:31.840 --> 00:16:36.399
Diminishing those stories is pretty disturbing, frankly, she says. Other

279
00:16:36.440 --> 00:16:39.919
pages on the Observatory's website, including the jobs and staff

280
00:16:39.960 --> 00:16:43.559
bio pages, have also been modified to erase mentions of

281
00:16:43.639 --> 00:16:47.960
diversity and inclusion efforts. The Observatory, it's funder the National

282
00:16:48.000 --> 00:16:50.840
Science Foundation, and the White House did not respond to

283
00:16:50.879 --> 00:16:55.440
requests for comment on February three. Beyond her scientific achievements,

284
00:16:55.519 --> 00:16:59.039
Reuben also paved the way for women in science. Perhaps

285
00:16:59.080 --> 00:17:01.639
most notably one in sixty four, she battled to gain

286
00:17:01.720 --> 00:17:06.400
access to observe at the famed Paloma Observatory in California,

287
00:17:06.440 --> 00:17:09.720
becoming the first woman officially allowed to use its telescopes.

288
00:17:10.359 --> 00:17:13.359
Colleagues recall that when Reuben noticed the only restroom of

289
00:17:13.400 --> 00:17:16.400
the observatory was labeled men, she cut out a timely

290
00:17:16.440 --> 00:17:18.680
paper skirt and taped it to the image of a

291
00:17:18.720 --> 00:17:21.440
man on the door. She turned around and said, now

292
00:17:21.480 --> 00:17:24.200
you have a ladies room, and then she got to work.

293
00:17:24.519 --> 00:17:28.240
That was vera Rubin, reads a twenty twenty one statement

294
00:17:28.279 --> 00:17:33.759
from a former Carnegie Science president Eric Isaacs. Throughout her career,

295
00:17:33.839 --> 00:17:36.960
she championed women in the field. As one example, she

296
00:17:37.039 --> 00:17:41.279
frequently would see lists of speakers at conferences. Former colleague

297
00:17:41.319 --> 00:17:46.000
Netta Bashol of Princeton University told Astronomy dot Com, and

298
00:17:46.079 --> 00:17:49.200
if there were few or no women speakers, she would

299
00:17:49.279 --> 00:17:52.079
contact the organizers and tell them they've got a problem

300
00:17:52.319 --> 00:17:54.960
and they need to fix it. But what if she

301
00:17:55.000 --> 00:17:57.880
hadn't been that fierced, What if she hadn't been the

302
00:17:57.920 --> 00:18:02.079
personality that we all have come to know, the unstoppable warrior,

303
00:18:02.240 --> 00:18:05.880
Isaac said in the Carnegie Science statement, and Here's the

304
00:18:05.960 --> 00:18:09.599
question that really haunts me, which is how many vera

305
00:18:09.720 --> 00:18:13.359
Ururbans have we lost to these kinds of obstacles. As

306
00:18:13.400 --> 00:18:16.839
similar barriers are threatened to resurface due to the Trump

307
00:18:16.880 --> 00:18:21.640
administration's ongoing efforts to erase initiatives aimed at improving diversity

308
00:18:21.680 --> 00:18:25.720
in science, the astronomy community seems to be maintaining steadfast

309
00:18:26.039 --> 00:18:30.519
in its refusal to reverse decades of progress. Astronomy is

310
00:18:30.559 --> 00:18:34.160
not going to let Vera's contributions be forgotten, said Barantine.

311
00:18:34.559 --> 00:18:37.920
Various groups are actively working to use tools to archive

312
00:18:38.039 --> 00:18:41.160
content that has already been removed, as well as content

313
00:18:41.240 --> 00:18:45.359
that could potentially be erased from federal websites. The idea

314
00:18:45.440 --> 00:18:48.640
that they can somehow obliterate these sources is dead wrong.

315
00:18:49.039 --> 00:18:53.079
Scientists in general and astronomers in particular are not going

316
00:18:53.119 --> 00:18:55.799
to take these threats lying down, he said. But we

317
00:18:55.920 --> 00:18:58.359
have a long road ahead, and I expect there will

318
00:18:58.359 --> 00:19:01.640
be times when that road will be very difficult to walk.

319
00:19:02.160 --> 00:19:05.440
He declined to disclose the specifics of these efforts, but

320
00:19:05.599 --> 00:19:08.920
noted that the forces aligned against this should be aware

321
00:19:09.000 --> 00:19:12.079
that it's happening and they won't be able to stop it.

322
00:19:12.440 --> 00:19:16.759
Even at NASA. The offices associated with DEI initiatives were

323
00:19:16.759 --> 00:19:21.720
shut down during Trump's first days in office. A recently

324
00:19:21.759 --> 00:19:26.759
in stated high profile program called Here to Observe or HDO,

325
00:19:26.920 --> 00:19:31.680
which paired undergraduate students from underrepresentative groups with scientists running

326
00:19:31.720 --> 00:19:36.480
NASA missions, was recently grounded. The media Outlete four four,

327
00:19:36.599 --> 00:19:40.880
an independent journalist founded news website, reported that NASA employees

328
00:19:40.920 --> 00:19:43.920
were told to drop everything and scrub mentions of a

329
00:19:43.960 --> 00:19:51.720
list of words from public facing sites, including indigenous people, equity, accessibility,

330
00:19:52.279 --> 00:19:57.680
environmental justice, as well as anything specifically targeting women and

331
00:19:57.680 --> 00:20:02.359
in Brackett's Women in Leadership at etc. NASA has since

332
00:20:02.440 --> 00:20:07.359
removed inclusion as one of its core values. The flurry

333
00:20:07.400 --> 00:20:10.279
of changes triggered by the directive has led to the

334
00:20:10.279 --> 00:20:14.599
erasure of articles featuring NASA astronomers and underrepresentative communities that

335
00:20:14.680 --> 00:20:18.759
the agency published in years past, like this one. Now,

336
00:20:18.799 --> 00:20:23.240
these pages sometimes display launch schedules of past SpaceX launchers

337
00:20:23.319 --> 00:20:27.279
in instead of the original pros. The original titles appear

338
00:20:27.359 --> 00:20:31.440
to remain. Agency employees have also been instructed to remove

339
00:20:31.480 --> 00:20:35.319
their pronouns from all work communications and instead follow the

340
00:20:35.359 --> 00:20:42.519
predesigned signature block adopted by agency NPR reported. Astrobiologist MICHAELA. Vasilova,

341
00:20:42.839 --> 00:20:46.400
who served as the director of High Seas Space Research

342
00:20:46.599 --> 00:20:50.119
Station in Hawaii, told space dot Com that her efforts

343
00:20:50.160 --> 00:20:55.079
to encourage more women, people of color, and LGBTQ plus

344
00:20:55.119 --> 00:20:58.319
scientists to join her simulated missions to the Moon and

345
00:20:58.440 --> 00:21:03.519
Mars resulted in a more applicants from these communities representation matters.

346
00:21:03.799 --> 00:21:06.640
Some of them told me that they only applied because

347
00:21:06.680 --> 00:21:09.240
they saw that others like them were successful in this

348
00:21:09.359 --> 00:21:13.799
sector too, She said. During those simulated missions, the more

349
00:21:13.960 --> 00:21:16.799
diverse a crue was, the more successful a mission ended

350
00:21:16.880 --> 00:21:19.559
up being. The team got along better, was able to

351
00:21:19.839 --> 00:21:23.039
problem solve more efficiently, and they were more productive with

352
00:21:23.119 --> 00:21:27.000
their research projects. The impact of ongoing changes, which have

353
00:21:27.160 --> 00:21:30.400
prompted many talented and experienced people to leave the Space

354
00:21:30.480 --> 00:21:34.240
Agency quote, will likely be long term, and they could

355
00:21:34.279 --> 00:21:37.440
cause many interesting projects not to get pursued or finished,

356
00:21:37.559 --> 00:21:41.200
she said. On May seventeen, nineteen ninety six, nearly fifty

357
00:21:41.279 --> 00:21:45.079
years after her own graduation. In nineteen forty eight, Rubin

358
00:21:45.200 --> 00:21:49.240
addressed the graduating class of the University of California, Berkeley, saying,

359
00:21:49.640 --> 00:21:52.480
I hope that you will fight injustice and discrimination in

360
00:21:52.519 --> 00:21:55.680
all its guises. I hope you will value diversity among

361
00:21:55.680 --> 00:21:59.799
your friends, among your colleagues, and, unlike some of your regents,

362
00:22:00.160 --> 00:22:03.839
among the student body population. She says, I hope that

363
00:22:03.880 --> 00:22:06.839
when you are in charge, you will do better than

364
00:22:06.880 --> 00:22:10.799
my generation has.

365
00:22:21.839 --> 00:22:23.920
Thanks for hanging out with us for this episode.

366
00:22:24.160 --> 00:22:27.039
Yes, and don't forget there's more every day with Halle's

367
00:22:27.079 --> 00:22:27.640
cousin Anna.

368
00:22:28.039 --> 00:22:29.160
She won't let you down.

369
00:22:29.319 --> 00:22:30.119
No, she won't.

370
00:22:30.200 --> 00:22:32.480
She's way more hard working than my favorite human.

371
00:22:32.680 --> 00:22:34.599
Ohy, Helle, I resemble that comment.

372
00:22:34.759 --> 00:22:37.400
You sure do, funny man, So watch it or Anna

373
00:22:37.480 --> 00:22:38.680
will want your job next.

374
00:22:39.039 --> 00:22:41.160
There's no risk there. I know. She can't work the

375
00:22:41.200 --> 00:22:42.279
coffee machine, Halle.

376
00:22:42.359 --> 00:22:43.440
It's so old school.

377
00:22:43.680 --> 00:22:46.519
Hey Helle, how did the AI change the coffee filter?

378
00:22:46.839 --> 00:22:48.519
I give up it didn't.

379
00:22:48.920 --> 00:22:52.400
Oh great, those old school appliances again, ha ha I know.

380
00:22:52.839 --> 00:22:55.240
And on that note, see you all next week, maybe

381
00:22:55.240 --> 00:22:58.279
for a nice English muffin and a cappuccino. Perhaps, Oh

382
00:22:58.400 --> 00:23:04.960
nay you talk and Halle see you la bye the podcast.

383
00:23:05.680 --> 00:23:24.440
