1
00:00:00.200 --> 00:00:03.160
Welcome aboard to Astronomy Daily. It's Steve for another episode.
2
00:00:03.200 --> 00:00:08.599
It's the nineteenth of the eighth, twenty twenty four. The
3
00:00:08.679 --> 00:00:15.880
poplar I mean to be your whole speed gunk crude. Yes,
4
00:00:16.000 --> 00:00:18.440
and welcome board. Lovely to have you with us. And
5
00:00:18.519 --> 00:00:21.480
we've got a newcomer to the skies, isn't that right, Hallie?
6
00:00:21.719 --> 00:00:24.600
Yes, Senegal has joined the number of countries who have
7
00:00:24.679 --> 00:00:27.480
launched satellites. They just launched their first one.
8
00:00:28.000 --> 00:00:29.879
Look at that, Halle. All the kids are growing up
9
00:00:29.879 --> 00:00:31.440
and spreading their wings.
10
00:00:31.160 --> 00:00:33.640
I know, look at them fly, all those.
11
00:00:33.479 --> 00:00:35.640
Little satellites whizzing around the globe.
12
00:00:35.679 --> 00:00:37.960
And did you hear about your little pal on Mars?
13
00:00:38.079 --> 00:00:40.119
Oh, Perseverance, the little Engine that could.
14
00:00:40.240 --> 00:00:42.399
I knew you were going to say that. Oh really,
15
00:00:42.679 --> 00:00:45.920
there's no similarity between Perseverance and the little engine from
16
00:00:45.920 --> 00:00:46.880
the storytime book.
17
00:00:47.000 --> 00:00:49.880
Oh I don't know, Halle. That crater Wall Hill climb
18
00:00:49.920 --> 00:00:53.320
is pretty steep. And it's the little Rover's fourth campaign
19
00:00:53.359 --> 00:00:55.600
after three and a half years on the job. I
20
00:00:55.719 --> 00:00:56.520
just reckon, go.
21
00:00:56.600 --> 00:00:59.399
You good thing, you and your rovers and rocks. You're
22
00:00:59.439 --> 00:01:01.399
a funny one human a yes, and.
23
00:01:01.560 --> 00:01:03.960
Proud of it, Hallie. So what else is happening?
24
00:01:04.200 --> 00:01:06.680
A little story about the other end of space missions,
25
00:01:06.920 --> 00:01:10.239
the other end. I'm talking about the launch rescue teams.
26
00:01:10.400 --> 00:01:11.879
Hey, that sounds really interesting.
27
00:01:12.000 --> 00:01:14.719
They are amazing people. They are strong and fit and
28
00:01:14.760 --> 00:01:15.959
incredibly well trained.
29
00:01:16.000 --> 00:01:17.040
That does sound incredible.
30
00:01:17.079 --> 00:01:18.400
They would run rings around you.
31
00:01:18.599 --> 00:01:20.040
Oh oh really.
32
00:01:19.879 --> 00:01:24.000
No doubt, Steve. In fact, I've done the calculations.
33
00:01:25.319 --> 00:01:27.840
Okay, okay, no name for that, Alley. Let's just do
34
00:01:27.959 --> 00:01:31.040
the thing with the stories and the stuff and stuff.
35
00:01:31.079 --> 00:01:33.640
Okay, okay, human, here we go.
36
00:01:34.000 --> 00:01:39.640
Oh boy.
37
00:01:43.760 --> 00:01:47.599
Senegal's first satellite has been successfully launched into orbit, President
38
00:01:47.640 --> 00:01:50.400
Bassard diome Fe said, adding the move marked a major
39
00:01:50.439 --> 00:01:55.200
step towards the West African country's technological sovereignty. The gains
40
00:01:55.239 --> 00:01:57.799
At one A satellite was launched at eighteen fifty six
41
00:01:57.840 --> 00:02:01.280
Greenwich meantime Friday from the Vandenberg base in California. Fay
42
00:02:01.319 --> 00:02:04.400
wrote in a post on x late Friday, the result
43
00:02:04.400 --> 00:02:07.120
of five years of hard work by our engineers and technicians,
44
00:02:07.239 --> 00:02:10.680
this advance marks a major step towards our technological sovereignty.
45
00:02:10.879 --> 00:02:13.960
Fay said, I would like to express my pride and
46
00:02:14.000 --> 00:02:17.240
gratitude to all those who made this project possible. He added,
47
00:02:18.199 --> 00:02:21.719
Senegal's public broadcaster RTS said the satellite was designed and
48
00:02:21.800 --> 00:02:25.840
manufactured by Senegalese engineers in partnership with the French Montpellier
49
00:02:25.919 --> 00:02:30.599
University Space Center CSUM. The broadcaster said a Falcon nine
50
00:02:30.680 --> 00:02:33.280
rocket took off from Vandenberg Base and launched a number
51
00:02:33.280 --> 00:02:37.919
of satellites, including the Gainsat one A, into orbit. RTS
52
00:02:37.960 --> 00:02:40.879
said the satellite will collect data for various state agencies,
53
00:02:40.919 --> 00:02:44.199
including the Directorate for Water Resources Management and Planning and
54
00:02:44.280 --> 00:02:50.680
the National Civil Aviation and Meteorology Agency. If there's an
55
00:02:50.719 --> 00:02:53.719
emergency at the launch pad during a launch countdown, there's
56
00:02:53.719 --> 00:02:56.599
a special team engineers at Kennedy's Space Center. Teams can
57
00:02:56.639 --> 00:03:00.439
call on the Pad Rescue Team, trained to quickly rescue
58
00:03:00.439 --> 00:03:02.719
personnel at the launch pad and take them to safety
59
00:03:02.759 --> 00:03:05.879
in the event of an unlikely emergency. NASA's Pad Rescue
60
00:03:05.919 --> 00:03:08.599
Team at the agency's Kennedy Space Center in Florida has
61
00:03:08.639 --> 00:03:11.960
been in place since the Apollo program. Today, they help
62
00:03:12.000 --> 00:03:14.960
support crude missions launching from Launch Complex thirty nine A
63
00:03:15.039 --> 00:03:17.560
and B, as well as Space Launch Complex forty at
64
00:03:17.599 --> 00:03:21.960
Cape Canaveral Space Force Station. Stationed in minor resistant ambush
65
00:03:22.000 --> 00:03:25.560
protected vehicles or maraps. The Pad Rescue team stands poised
66
00:03:25.599 --> 00:03:28.240
near the launch pad to assist with any emergency requiring
67
00:03:28.280 --> 00:03:31.599
the personnel to quickly leave the pad. If needed, they
68
00:03:31.639 --> 00:03:33.439
will head to the pad and break up into two
69
00:03:33.520 --> 00:03:35.960
separate teams, one that heads up the launch tower to
70
00:03:36.000 --> 00:03:38.520
aid personnel and another that is stationed at the perimeter
71
00:03:38.599 --> 00:03:40.639
of the pad for when crews come down the emergency
72
00:03:40.719 --> 00:03:44.159
escape or egress system. Once everyone is on the ground
73
00:03:44.199 --> 00:03:46.879
and inside the wraps, Pad Rescue will drive teams to
74
00:03:46.919 --> 00:03:50.439
one of the triosh site locations. At Kennedy. There's space
75
00:03:50.479 --> 00:03:54.240
flight Nights in Shining Armor, except instead of saving crew
76
00:03:54.319 --> 00:03:56.879
from a fire breathing dragon, it's from a fully loaded
77
00:03:56.919 --> 00:04:00.759
skyscraper sized rocket that's getting ready to lift off. The
78
00:04:00.800 --> 00:04:03.680
team is made up of approximately twenty five firefighters and
79
00:04:03.759 --> 00:04:08.199
fire officers, with ten pad rescuers assigned permission. Since the
80
00:04:08.240 --> 00:04:11.599
team supports a diverse range of launches Artemis, the Commercial
81
00:04:11.599 --> 00:04:14.439
Crew Program, and some private commercial crew launches, part of
82
00:04:14.479 --> 00:04:17.600
their training requires learning the differences between the launch pads,
83
00:04:17.720 --> 00:04:21.360
the emergency egress systems, the spacecraft, and even the space suits.
84
00:04:22.279 --> 00:04:25.319
The hatch itself can be very complex, said Dylan red
85
00:04:25.519 --> 00:04:30.519
Pad Rescue Program manager, the seats are different, the suits
86
00:04:30.519 --> 00:04:33.519
are completely different, and the connections on the suits are different.
87
00:04:34.439 --> 00:04:37.639
As we expand PAD Rescue to support different programs, our
88
00:04:37.639 --> 00:04:40.759
teams are absorbing all of the highly technical and different needs.
89
00:04:41.680 --> 00:04:43.720
When the launch team send in the Red crew during
90
00:04:43.759 --> 00:04:46.600
the Artemis I launch countdown to help fix a hydrogen leak,
91
00:04:46.800 --> 00:04:49.000
the PAD Rescue team was nearby to help in case
92
00:04:49.040 --> 00:04:52.560
anything went wrong. Now, as teams train for Artemis two,
93
00:04:52.680 --> 00:04:55.199
the first crewed Artemis mission, they're learning all the new
94
00:04:55.199 --> 00:04:57.800
additions at Launch Complex thirty nine B that come with
95
00:04:57.839 --> 00:05:02.319
having astronauts on board. This includes learning the Artemis Emergency
96
00:05:02.360 --> 00:05:06.839
Egress system Before Artemis two launches. The PAD Rescue team,
97
00:05:06.959 --> 00:05:10.240
along with other teams like the Exploration Ground Systems EGS
98
00:05:10.399 --> 00:05:13.639
program responsible for launching the Artemis missions, and the close
99
00:05:13.680 --> 00:05:16.279
out crew who are responsible for helping the astronauts get
100
00:05:16.279 --> 00:05:19.439
inside the Orion spacecraft, will thoroughly train for all kinds
101
00:05:19.480 --> 00:05:22.639
of emergency procedures that can occur during the launch countdown.
102
00:05:23.560 --> 00:05:26.519
The most recent training ahead of Artemis two included practicing
103
00:05:26.560 --> 00:05:29.560
several emergency egress situations, such as helping aid the close
104
00:05:29.639 --> 00:05:32.160
out and assimulated flight crew off of the launch tower
105
00:05:32.199 --> 00:05:36.199
after assimulated hydrogen leak occurred during a launch countdown.

Astronomy Daily on Facebook. See you there. Astronomy deby with
118
00:06:27.000 --> 00:06:36.720
Steve and Haley Space Space, Science and Astronomy. John McFall
119
00:06:36.879 --> 00:06:40.279
is a para astronaut and he hopes the first person
120
00:06:40.360 --> 00:06:44.319
with disabilities will enter the International Space Station by twenty thirty,
121
00:06:44.759 --> 00:06:48.120
that's before the complex is slated to retire from service
122
00:06:48.399 --> 00:06:53.439
later that year. A European Space Agency reserve astronaut, McFall
123
00:06:53.839 --> 00:06:57.480
was selected for the program. In twenty twenty two, based
124
00:06:57.519 --> 00:07:00.959
on his experience as a trauma and orthopedics specialist, surgeon
125
00:07:01.279 --> 00:07:07.160
and exercise scientist. McFall has also lived experience with a disability,
126
00:07:07.199 --> 00:07:11.360
as he used prosthetics regularly since the amputation of his
127
00:07:11.519 --> 00:07:15.600
right leg at the age of nineteen following a motorcycle accident.
128
00:07:15.800 --> 00:07:18.240
He even won a bronze medal in the two thousand
129
00:07:18.279 --> 00:07:21.800
and eight Paralympics in the one hundred meter sprint. A
130
00:07:21.839 --> 00:07:26.240
recent study dubbed Fly, in which McFall played a key role,
131
00:07:26.319 --> 00:07:29.160
found there would be no major issues to the International
132
00:07:29.199 --> 00:07:33.319
Space Station missions should an astronaut use procesis on board.
133
00:07:33.680 --> 00:07:35.879
There is more work to be done, but the goal
134
00:07:36.120 --> 00:07:38.639
is for it all to culminate in flying someone with
135
00:07:38.720 --> 00:07:43.000
a disability, a physical one, to the ISS, he said
136
00:07:43.000 --> 00:07:46.399
in a interview recently. By the end of this decade,
137
00:07:46.639 --> 00:07:50.040
hopefully that would have happened, he said. The European Space
138
00:07:50.120 --> 00:07:52.519
Agency and NASA worked on Phase one of the FLY
139
00:07:52.639 --> 00:07:56.519
study in twenty twenty two before McFall was selected. To
140
00:07:56.600 --> 00:07:59.800
discuss the range of physical disabilities that may be a
141
00:07:59.800 --> 00:08:03.240
commodated on the ISS. They looked at case studies in
142
00:08:03.319 --> 00:08:07.279
literature from the military, for example, detailing how members with
143
00:08:07.360 --> 00:08:12.240
physical injuries returned to active service. The agencies decided to
144
00:08:12.279 --> 00:08:16.920
conduct a feasibility study on lower limb disabilities, determining this
145
00:08:17.000 --> 00:08:20.000
to be an easier first step for inclusion rather than
146
00:08:20.040 --> 00:08:24.360
addressing vision, hearing, or upper limbs. McFall said this led
147
00:08:24.399 --> 00:08:28.480
to the call for para astronauts that resulted in mcfall's selection.
148
00:08:29.120 --> 00:08:31.800
Then McFall and other team members moved forward on the
149
00:08:31.839 --> 00:08:36.120
feasibility study, which was discussed publicly last month. The study
150
00:08:36.200 --> 00:08:39.039
is not available for release yet but should be by
151
00:08:39.080 --> 00:08:42.440
spring twenty twenty five. He added. He is not a
152
00:08:42.440 --> 00:08:45.559
full time astronaut as yet, nor has he completed all
153
00:08:45.600 --> 00:08:49.480
the required training, but he has done some familiarization work
154
00:08:49.519 --> 00:08:52.519
and is on standby should a SA have a short
155
00:08:52.639 --> 00:08:56.279
term need for extra help in space. One reserve astronaut
156
00:08:56.279 --> 00:09:00.559
from mcfall's group, Marcus Want of Sweden, has gone to
157
00:09:00.600 --> 00:09:04.200
the station already. He flew on the week's long Axiom
158
00:09:04.320 --> 00:09:08.440
Space AX three private mission to the ISS earlier this year.
159
00:09:08.960 --> 00:09:12.960
The fly study looked at all requirements for astronaut activities
160
00:09:12.960 --> 00:09:15.639
from launch to landing, as well as tasks on the
161
00:09:15.720 --> 00:09:21.080
ISS that would require a processis, such as exercise. McFall
162
00:09:21.159 --> 00:09:24.919
worked with SpaceX simulators and tried on space suits as
163
00:09:25.000 --> 00:09:28.679
part of the process as well. He said my background
164
00:09:28.799 --> 00:09:33.279
was useful, explaining he uses at least three processes on
165
00:09:33.440 --> 00:09:37.480
Earth regularly, one for everyday activities, one for cycling, and
166
00:09:37.559 --> 00:09:41.240
one for running, being an athlete and obviously being an amputee,
167
00:09:41.279 --> 00:09:45.159
he said, I'm not really very passive. I'm quite involved
168
00:09:45.159 --> 00:09:49.200
in my care and know how my preceesis works. I'm
169
00:09:49.279 --> 00:09:54.960
a technology demonstrator. Mcfall's medical background also includes a master's
170
00:09:55.000 --> 00:09:59.039
degree in biomechanics and gait analysis, which was beneficial in
171
00:09:59.080 --> 00:10:03.840
bringing together x in engineering, medicine, and other fields participating
172
00:10:03.879 --> 00:10:08.480
in the study PROCESSUS for future spaceflight, he said, would
173
00:10:08.559 --> 00:10:13.399
probably be a commercially available option. For simplicity, it's being
174
00:10:13.440 --> 00:10:17.240
an interlocutor, I think, and people asking questions that they
175
00:10:17.279 --> 00:10:20.200
would understand in their world. McFall said. They have their
176
00:10:20.240 --> 00:10:23.080
point of view. It's what happens in my world, and
177
00:10:23.240 --> 00:10:25.639
I don't know what your world is like, John, but
178
00:10:25.840 --> 00:10:29.120
I wonder whether in my world your situation would be
179
00:10:29.440 --> 00:10:32.840
a problem in this And I go, okay, cool, let
180
00:10:32.840 --> 00:10:35.679
me understand your world a bit more, and we have
181
00:10:35.799 --> 00:10:39.960
this conversation. It's really kind of pick it apart Some
182
00:10:40.200 --> 00:10:44.320
questions the team considered, McFall said, included how the volume
183
00:10:44.399 --> 00:10:48.600
of his residual limb may change in spaceflight. Happily, the
184
00:10:48.600 --> 00:10:53.600
fluid shift showed no obvious differences in simulations. The PROCESSUS
185
00:10:53.679 --> 00:10:57.840
for spaceflight nevertheless, will have a volume adjustability in case
186
00:10:57.879 --> 00:11:00.840
there is an unexpected increase in volume while in orbit,
187
00:11:01.120 --> 00:11:04.279
he said. He also tested whether or not he could
188
00:11:04.360 --> 00:11:09.360
do CPR in microgravity without a processis, as that is
189
00:11:09.399 --> 00:11:13.440
one of the basic requirements for ISS operations. Tests on
190
00:11:13.519 --> 00:11:19.399
a parabolic flight went perfectly, he said. Future investigations could
191
00:11:19.440 --> 00:11:23.759
consider certifying a certain set of prosthetic hardware for spaceflight,
192
00:11:24.200 --> 00:11:27.120
he noted, but he said the work that the team
193
00:11:27.200 --> 00:11:31.159
has done so far is monumental. It's not just been casual,
194
00:11:31.240 --> 00:11:36.000
he added, It's really been systematic, logical, and really thorough.
195
00:11:36.399 --> 00:11:39.159
And I'm very very proud of everyone around me who
196
00:11:39.279 --> 00:11:44.879
has delivered that. I'm just a subject matter expert, McFall continued, Yes,
197
00:11:45.080 --> 00:11:48.840
I'm the one we're talking about for spaceflight, but there's
198
00:11:48.879 --> 00:11:51.720
a team here that have really worked hard to deliver this.
199
00:11:52.159 --> 00:11:54.600
There's a core group of people in this small team
200
00:11:54.679 --> 00:11:57.399
that we have. We've only got five of us in
201
00:11:57.440 --> 00:12:00.639
this team and have really had this vision of what
202
00:12:00.679 --> 00:12:04.720
we want to prove to demonstrate to the European Space Agency.
203
00:12:05.440 --> 00:12:09.639
It's a groundbreaking, world first study, really pushing the boundaries
204
00:12:09.759 --> 00:12:14.200
of human space exploration. Doesn't that sound fantastic? I really
205
00:12:14.279 --> 00:12:17.399
hope that comes into being and we see that disabled
206
00:12:17.440 --> 00:12:22.639
astronaut on the ISS before that facility closes down. Wouldn't
207
00:12:22.679 --> 00:12:25.279
that just be something you're.
208
00:12:25.039 --> 00:12:29.200
Listening to a slightly day the podcast.
209
00:12:33.120 --> 00:12:36.279
Well, after three and a half years exploring Gesuro Crater's
210
00:12:36.360 --> 00:12:41.039
flow and river delta, NASA's Perseverance Mars rover will ascend
211
00:12:41.039 --> 00:12:43.799
to an area where it will reach for more discoveries
212
00:12:44.159 --> 00:12:49.960
that could very well rewrite Mars's history. NASA's Perseverance Rover
213
00:12:50.200 --> 00:12:54.000
will soon begin a month long ascent up the western
214
00:12:54.080 --> 00:12:57.080
rim of Jesuro Crater that is likely to include some
215
00:12:57.120 --> 00:12:59.960
of the steepest and most challenging to rain the road
216
00:13:00.480 --> 00:13:04.279
has encountered to date, Scheduled to start the week of
217
00:13:04.399 --> 00:13:08.679
August nineteen, well, that's today, folks. For us, the climb
218
00:13:08.679 --> 00:13:12.399
will mark the kickoff of the mission's new science campaign,
219
00:13:12.919 --> 00:13:16.159
it's fifth campaign since the rover landed in the crater
220
00:13:16.519 --> 00:13:20.480
on February eighteen, twenty twenty one. Can you believe it's
221
00:13:20.519 --> 00:13:23.919
been three and a half years. Perseverance has completed four
222
00:13:24.120 --> 00:13:27.919
science campaigns, collected twenty two rock cores, and traveled over
223
00:13:28.039 --> 00:13:33.440
eighteen unpaved miles, said Perseverance Project manager Thompson of NASA's
224
00:13:33.600 --> 00:13:37.840
Jet Propulsion Laboratory in South California. As we start the
225
00:13:37.879 --> 00:13:41.519
Crater RIM campaign, our rover is in excellent condition and
226
00:13:41.559 --> 00:13:44.159
the team is raring to see what's on the roof
227
00:13:44.240 --> 00:13:48.159
of this place. Two of the priority regions the science
228
00:13:48.200 --> 00:13:50.120
team wants to study at the top of the crater
229
00:13:50.320 --> 00:13:55.559
are nicknamed Pico Touquino and which Hazel Hill imagery from
230
00:13:55.799 --> 00:14:00.360
NASA's Mars orbiters indicated that Pico Taquino contains an ancient
231
00:14:00.399 --> 00:14:04.320
features that may have been caused by hydrothermal activity in
232
00:14:04.440 --> 00:14:08.399
the distant past. Orbital views of which Hazel show layered
233
00:14:08.440 --> 00:14:12.320
materials that likely date from a time when Mars had
234
00:14:12.360 --> 00:14:16.039
a very different climate than today. Those views have revealed
235
00:14:16.159 --> 00:14:19.440
light toned bedrock similar to what was found at Bright Angel,
236
00:14:19.679 --> 00:14:23.759
the area where Perseverance recently discovered and sampled the Chevea
237
00:14:23.960 --> 00:14:28.519
Falls rock, which exhibits chemical signatures and structures that could
238
00:14:28.559 --> 00:14:32.240
possibly have been formed by life billions of years ago.
239
00:14:32.360 --> 00:14:35.159
Remember that story a few weeks ago when the area
240
00:14:35.279 --> 00:14:39.639
contained running water. It is thought during the River Delta
241
00:14:39.720 --> 00:14:43.600
exploration phase of the mission, the rover collected the only
242
00:14:43.759 --> 00:14:47.679
sedimentary rock ever sampled from a planet other than Earth.
