00:00:24.440 --> 00:00:27.519
We'll also look at a potential new spaceport collaboration between
9
00:00:27.600 --> 00:00:30.920
China and Malaysia. And here about astronaut Don Pettitt, who
10
00:00:31.000 --> 00:00:34.840
recently celebrated his seventieth birthday in quite the extraordinary way
11
00:00:35.119 --> 00:00:38.079
returning from space. So settle in for your daily dose
12
00:00:38.079 --> 00:00:41.439
of astronomical wonders as we journey through today's space headlines.
13
00:00:42.880 --> 00:00:46.039
The NASA team behind the Nancy Grace Roman Space Telescope
14
00:00:46.359 --> 00:00:50.399
has just shared exciting designs for the mission's three core surveys,
15
00:00:50.960 --> 00:00:54.840
set to launch in twenty twenty seven. This revolutionary telescope
16
00:00:54.880 --> 00:00:58.240
represents a significant leap forward in our ability to study
17
00:00:58.240 --> 00:01:01.719
the Cosmos. What makes home and truly special is its
18
00:01:01.840 --> 00:01:05.719
unprecedented field of view, a staggering one hundred times greater
19
00:01:06.000 --> 00:01:10.079
than that of the Hubble Space Telescope. This panoramic capability
20
00:01:10.239 --> 00:01:13.560
will allow scientists to capture vast regions of space in
21
00:01:13.640 --> 00:01:20.439
extraordinary detail, opening new frontiers in astronomical research. According to Gaelzasowski,
22
00:01:20.480 --> 00:01:23.200
an associate professor at the University of Utah and co
23
00:01:23.319 --> 00:01:27.439
chair of the ROMAN Observations Time Allocation Committee, the telescope's
24
00:01:27.439 --> 00:01:30.920
primary mission is to answer fundamental questions about dark energy,
25
00:01:31.319 --> 00:01:35.400
dark matter, and planets beyond our Solar system, But perhaps
26
00:01:35.439 --> 00:01:39.000
more importantly, it aims to equip space researchers with powerful
27
00:01:39.040 --> 00:01:43.239
new tools and data for scientific investigation. The three survey
28
00:01:43.280 --> 00:01:45.959
designs will account for about seventy five percent of roman's
29
00:01:46.000 --> 00:01:49.680
observations during its five year primary mission. The largest of
30
00:01:49.719 --> 00:01:52.799
these is the High Latitude Wide Area Survey, which will
31
00:01:52.799 --> 00:01:55.879
reveal more than a billion galaxies across the lifetime of
32
00:01:55.920 --> 00:01:59.719
the universe. By studying the distribution and shape of these
33
00:01:59.760 --> 00:02:03.799
gaps galaxies, scientists hope to better understand dark energy, the
34
00:02:03.879 --> 00:02:09.520
mysterious force behind our universe's accelerating expansion. The second core survey,
35
00:02:09.599 --> 00:02:13.360
the High Latitude Time Domain survey will repeatedly observe the
36
00:02:13.439 --> 00:02:16.759
same region of space to track how celestial objects change
37
00:02:16.759 --> 00:02:20.280
over time. This will help scientists study phenomena like black
38
00:02:20.280 --> 00:02:24.039
hole formations, stars falling into black holes, and other variable
39
00:02:24.080 --> 00:02:29.319
celestial events. Unlike the outward looking surveys, the third core project,
40
00:02:29.479 --> 00:02:33.080
the Galactic Bulge Time Domain Survey, will peer directly into
41
00:02:33.080 --> 00:02:36.159
the heart of our own Milky Way galaxy. This deep,
42
00:02:36.280 --> 00:02:39.879
detailed view will allow astronomers to monitor hundreds of millions
43
00:02:39.919 --> 00:02:45.759
of stars, including those potentially harboring habitable worlds. Julie McKenny Romans,
44
00:02:45.800 --> 00:02:49.319
senior project scientist at NASA Goddard, notes that these survey
45
00:02:49.360 --> 00:02:52.719
designs represent the culmination of two years of input from
46
00:02:52.759 --> 00:02:55.840
over one thousand scientists across more than three hundred and
47
00:02:55.840 --> 00:03:00.759
fifty institutions worldwide. The mission promises to dramatically advance our
48
00:03:00.840 --> 00:03:04.360
understanding of the universe and deliver new insights into some
49
00:03:04.400 --> 00:03:09.039
of astronomy's most profound mysteries. Moving on now to a
50
00:03:09.080 --> 00:03:12.240
launch that has successfully happened. Amazon has officially taken a
51
00:03:12.280 --> 00:03:15.439
major step into the satellite Internet arena with the successful
52
00:03:15.479 --> 00:03:19.280
launch of twenty seven Project Kuiper Broadband spacecraft on April
53
00:03:19.319 --> 00:03:22.639
twenty eighth, a United Launch Alliance at Las V rocket
54
00:03:22.680 --> 00:03:26.159
blasted off from Florida's Cape Canaveral Space Force Station at
55
00:03:26.199 --> 00:03:29.639
seven oh one pm Eastern Time, carrying these satellites toward
56
00:03:29.680 --> 00:03:33.199
their new home in low Earth orbit. This marks just
57
00:03:33.240 --> 00:03:37.360
the beginning of a massive deployment plan. Amazon will need
58
00:03:37.400 --> 00:03:40.439
more than eighty planned launches to fully build out the
59
00:03:40.479 --> 00:03:45.680
Project Kuyper Mega constellation, which will eventually comprise over three thousand,
60
00:03:45.759 --> 00:03:49.599
two hundred satellites orbiting approximately three hundred ninety two miles
61
00:03:49.680 --> 00:03:54.319
above Earth's surface. While impressive, this number still falls short
62
00:03:54.360 --> 00:03:58.199
of SpaceX's Starlink network, which already has more than seven
63
00:03:58.240 --> 00:04:02.400
thy two hundred operational saturlles and continues to expand rapidly.
64
00:04:02.879 --> 00:04:06.639
The competition between these tech giants is intensifying. In fact,
65
00:04:07.000 --> 00:04:10.240
SpaceX launched its own Starlink mission less than three hours
66
00:04:10.240 --> 00:04:14.639
before Amazon's launch, with another following just hours afterward. This
67
00:04:14.759 --> 00:04:18.199
pace highlights the aggressive expansion of the satellite internet market,
68
00:04:18.439 --> 00:04:21.560
with multiple companies racing to secure their position in Earth's
69
00:04:21.560 --> 00:04:27.439
increasingly crowded orbital highways. For Amazon, this operational milestone comes
70
00:04:27.480 --> 00:04:31.319
after an initial test launch last October when two prototype
71
00:04:31.319 --> 00:04:34.839
satellites were sent into orbit to validate the company's technology.
72
00:04:35.519 --> 00:04:40.040
The satellites' launch now represents significant improvements over those early prototypes,
73
00:04:40.040 --> 00:04:45.160
with enhanced performance across all systems, including phased array antennas, processors,
74
00:04:45.680 --> 00:04:50.680
solar arrays, propulsion systems, and optical intersatellite links. The company
75
00:04:50.680 --> 00:04:54.279
has also addressed concerns from the astronomical community by coding
76
00:04:54.319 --> 00:04:58.240
the satellites with a unique dielectric mirror film that scatters
77
00:04:58.279 --> 00:05:02.480
reflected sunlight make them less visible to ground based observers.
78
00:05:03.120 --> 00:05:06.879
This demonstrates Amazon's awareness of the growing concerns about satellite
79
00:05:06.879 --> 00:05:12.720
constellations interfering with astronomical observations. If all proceeds according to plan,
80
00:05:12.839 --> 00:05:15.920
the Atlas V rocket will deploy these twenty seven satellites
81
00:05:16.160 --> 00:05:19.319
at an altitude of two hundred eighty miles, after which
82
00:05:19.360 --> 00:05:22.160
they'll use their own propulsion systems to reach their final
83
00:05:22.199 --> 00:05:26.759
operational orbit. Amazon expects to begin providing initial coverage to
84
00:05:26.800 --> 00:05:30.759
customers later this year as the constellation takes shape. The
85
00:05:30.839 --> 00:05:33.759
majority of the remaining launches will be handled by ULA's
86
00:05:33.839 --> 00:05:38.800
Atlas V and its successor, the Vulcan Centaur rocket. Amazon
87
00:05:38.839 --> 00:05:41.639
has also diversified its launch partners by signing deals with
88
00:05:41.720 --> 00:05:45.720
Jeff Bezos's Blue Origin SpaceX and France based Ariane Space,
89
00:05:46.240 --> 00:05:50.160
ensuring multiple pathways to orbit as this ambitious project moves forward.
90
00:05:51.639 --> 00:05:55.480
Next up, in a significant milestone for Earth observation science,
91
00:05:55.920 --> 00:06:00.839
the European Space Agency has successfully launched its groundbreaking Biomas satellite,
92
00:06:01.079 --> 00:06:04.439
designed to revolutionize our understanding of the world's forests and
93
00:06:04.480 --> 00:06:08.120
their critical role in Earth's carbon cycle. The satellite lifted
94
00:06:08.120 --> 00:06:10.959
off aboard a Vegas Sea rocket from Europe's spaceport in
95
00:06:11.040 --> 00:06:14.920
French Guiana on April twenty ninth at eleven fifteen Central
96
00:06:14.959 --> 00:06:19.240
European summertime. Less than an hour after the dramatic lift off,
97
00:06:19.560 --> 00:06:22.680
the satellite separated from the rocket's upper stage as planned.
98
00:06:23.279 --> 00:06:26.800
Mission controllers at ESA's European Space Operation Center in Germany
99
00:06:26.839 --> 00:06:29.639
received the crucial first signal at twelve twenty eight cust
100
00:06:30.160 --> 00:06:34.279
confirming that Biomass is functioning properly in orbit. This signal,
101
00:06:34.639 --> 00:06:38.120
relayed via the Troll ground station in Antarctica, marked the
102
00:06:38.120 --> 00:06:42.120
beginning of the satellite's operational life. Over the coming days,
103
00:06:42.199 --> 00:06:45.040
controllers will focus on the launch and early orbit phase,
104
00:06:45.519 --> 00:06:49.759
meticulously verifying all systems and executing a series of intricate
105
00:06:49.800 --> 00:06:54.480
maneuvers to deploy the satellite's impressive twelve meter wide mesh reflector,
106
00:06:54.920 --> 00:06:57.600
which is supported by a seven point five meter boom.
107
00:06:58.319 --> 00:07:02.079
This delicate unfolding process is critical to the mission's success.
108
00:07:03.120 --> 00:07:06.480
What makes Biomass truly revolutionary is its P band synthetic
109
00:07:06.519 --> 00:07:10.079
aperture radar. The first of its kind in space. This
110
00:07:10.120 --> 00:07:14.120
specialized instrument can penetrate forest canopies to measure woody biomass,
111
00:07:14.519 --> 00:07:18.160
the trunks, branches, and stems where most forest carbon is stored.
112
00:07:18.639 --> 00:07:21.439
These measurements will serve as a proxy for carbon storage,
113
00:07:21.839 --> 00:07:24.680
allowing scientists to track how much carbon is being stored
114
00:07:24.680 --> 00:07:28.959
in forests worldwide. Forests play an absolutely vital role in
115
00:07:29.000 --> 00:07:32.639
Earth's carbon cycle by absorbing and storing vast amounts of
116
00:07:32.680 --> 00:07:37.199
carbon dioxide, helping to regulate our planet's temperature. Often referred
117
00:07:37.240 --> 00:07:41.600
to as Earth's green lungs, forests absorb approximately eight billion
118
00:07:41.680 --> 00:07:46.839
tons of carbon dioxide annually. However, deforestation and degradation, particularly
119
00:07:46.920 --> 00:07:49.800
in tropical regions, are releasing this stored carbon back into
120
00:07:49.839 --> 00:07:53.839
the atmosphere. One of the major challenges scientists and policy
121
00:07:53.839 --> 00:07:57.240
makers face is the current lack of accurate data on
122
00:07:57.319 --> 00:08:00.639
forest carbon storage and how these stocks are changing due
123
00:08:00.639 --> 00:08:05.319
to rising temperatures, increased atmospheric carbon dioxide, and human driven
124
00:08:05.399 --> 00:08:10.000
land use changes. Biomass aims to fill this critical knowledge gap.
125
00:08:10.560 --> 00:08:14.000
The data collected by this mission will significantly reduce uncertainties
126
00:08:14.000 --> 00:08:17.879
in carbon stock and flux estimates, including those related to
127
00:08:17.959 --> 00:08:22.639
land use change, forest loss and regrowth. Beyond carbon monitoring,
128
00:08:22.680 --> 00:08:26.480
BIOMASS will also enable mapping of subsurface geology in deserts,
129
00:08:26.839 --> 00:08:31.240
ice sheet structures and forest floor topography, providing a multifaceted
130
00:08:31.319 --> 00:08:34.039
view of our planet that has never before been possible
131
00:08:34.039 --> 00:08:38.039
from space. Developed by a consortium of over fifty companies
132
00:08:38.120 --> 00:08:42.320
led by Airbus UK, the Biomass mission represents a new
133
00:08:42.360 --> 00:08:46.399
frontier in Earth observation technology, one that promises to enhance
134
00:08:46.440 --> 00:08:49.200
our understanding of forest's roles in the carbon cycle and
135
00:08:49.279 --> 00:08:53.399
climate system for years to come. China is exploring the
136
00:08:53.519 --> 00:08:57.120
establishment of its first overseas launch site with a proposed
137
00:08:57.159 --> 00:09:02.080
equatorial spaceport in Malaysia, a move that can carry's significant strategic, economic,
138
00:09:02.120 --> 00:09:06.840
and geopolitical implications. The China Great Wall Industry Corporation has
139
00:09:06.879 --> 00:09:09.519
signed a letter of intent with the Pahang State Development
140
00:09:09.559 --> 00:09:15.080
Corporation and Lestari Aankasa, a Malaysian private company actively involved
141
00:09:15.080 --> 00:09:18.759
in the country's space sector. The Malaysian state government has
142
00:09:18.799 --> 00:09:21.919
agreed to a one year feasibility study for the proposed
143
00:09:21.919 --> 00:09:26.919
spaceport in Pahung. If approved, this ambitious project, named the
144
00:09:26.919 --> 00:09:30.559
Pahung International Spaceport, could be completed within the next three
145
00:09:30.600 --> 00:09:34.240
to five years and create more than two thousand job opportunities,
146
00:09:34.600 --> 00:09:39.639
along with substantial spillover economic benefits in tourism, research, and
147
00:09:39.720 --> 00:09:44.360
technology sectors. What makes this location particularly valuable is its
148
00:09:44.440 --> 00:09:48.600
near equatorial position, situated at approximately three to four degrees
149
00:09:48.679 --> 00:09:52.399
north latitude. Launching rockets near the equator allows them to
150
00:09:52.440 --> 00:09:56.600
benefit from Earth's rotational speed, enabling heavier payloads and more
151
00:09:56.600 --> 00:10:01.159
efficient fuel usage. This natural advantage could signific enhance China's
152
00:10:01.200 --> 00:10:05.440
launch capabilities and reduce costs. A delegation from the Malaysian
153
00:10:05.519 --> 00:10:10.039
organizations is expected to visit Wenchang Space City in Hainan,
154
00:10:10.480 --> 00:10:14.840
South China in May to further discuss the project. China
155
00:10:14.879 --> 00:10:18.360
Great Wall Industry Corporation, which operates under the state owned
156
00:10:18.399 --> 00:10:23.039
space contractor CASSI, is the sole commercial organization authorized by
157
00:10:23.039 --> 00:10:27.799
the Chinese government to provide satellites, commercial launch services, and
158
00:10:27.960 --> 00:10:33.279
carry out international space cooperation. While the Pahang International Spaceport
159
00:10:33.320 --> 00:10:37.320
remains in an early tentative phase, experts note several potential
160
00:10:37.320 --> 00:10:40.759
benefits for China. New launch facilities could help ease a
161
00:10:40.759 --> 00:10:44.360
bottleneck in China's access to space, particularly in terms of
162
00:10:44.440 --> 00:10:48.399
launch frequency. The spaceport could provide options for commercial and
163
00:10:48.440 --> 00:10:52.000
civil missions, though more sensitive missions would likely remain within
164
00:10:52.120 --> 00:10:56.679
China's borders. For Malaysia, hosting the first spaceport in Southeast
165
00:10:56.720 --> 00:10:59.919
Asia would represent a significant leap forward in the country's
166
00:11:00.080 --> 00:11:05.919
technological capabilities and regional standing. During Chinese President Shi Jinping's
167
00:11:05.960 --> 00:11:08.799
recent state visit to Malaysia in mid April, the two
168
00:11:08.879 --> 00:11:12.399
countries issued a joint statement recognizing the great potential for
169
00:11:12.440 --> 00:11:16.200
strengthening cooperation in the space sector, aiming to jointly enhance
170
00:11:16.240 --> 00:11:21.360
space capabilities, cultivate the space economy, promote technological progress, and
171
00:11:21.480 --> 00:11:26.279
safeguard national security. There are challenges to consider, including geographical
172
00:11:26.320 --> 00:11:30.600
issues related to airline flight paths, shipping lanes, and overflight
173
00:11:30.600 --> 00:11:35.519
of neighboring countries, particularly Indonesia. Regional dynamics also come into
174
00:11:35.559 --> 00:11:38.360
play as Indonesia has been making its own space policy
175
00:11:38.360 --> 00:11:42.679
moves lately, highlighting the traditional rivalry between these Southeast Asian nations.
176
00:11:43.679 --> 00:11:47.759
If successful, this project would symbolize China's growing global ambitions
177
00:11:47.799 --> 00:11:52.159
in space, extending their launch infrastructure beyond mainland China for
178
00:11:52.200 --> 00:11:55.879
the first time and potentially reshaping the regional balance of
179
00:11:55.919 --> 00:12:02.120
space capabilities in Southeast Asia today. A celebration with a difference.
180
00:12:02.919 --> 00:12:05.600
Not many people celebrate their birthday by burning a fiery
181
00:12:05.720 --> 00:12:08.600
arc through the atmosphere, pulling four point four g's in
182
00:12:08.679 --> 00:12:11.759
free fall back to Earth, thudding into the ground, and
183
00:12:11.879 --> 00:12:15.320
emptying their stomach on the steps of Kazakhstan. But that's
184
00:12:15.360 --> 00:12:19.559
exactly how NASA astronaut Don Pettit marked his seventieth birthday,
185
00:12:20.000 --> 00:12:23.399
making him the oldest person to endure such a physically
186
00:12:23.440 --> 00:12:28.120
demanding return from a long duration mission. Pettit recently completed
187
00:12:28.120 --> 00:12:31.000
two hundred and twenty days aboard the International Space Station,
188
00:12:31.559 --> 00:12:34.720
adding to his impressive career total of five hundred ninety
189
00:12:34.799 --> 00:12:39.080
days in space, the third most all time among NASA astronauts.
190
00:12:39.919 --> 00:12:43.240
Just over a week after his dramatic return, Pettitt met
191
00:12:43.279 --> 00:12:46.279
with reporters at Johnson Space Center to share his experiences.
192
00:12:47.279 --> 00:12:50.039
It's good to be back on planet Earth, he said.
193
00:12:50.200 --> 00:12:53.080
As much as I love exploring space, going into the
194
00:12:53.080 --> 00:12:56.840
frontier and making observations, you do reach a time when
195
00:12:56.879 --> 00:13:00.720
it's time to come home. Pettit, who I first ventured
196
00:13:00.759 --> 00:13:03.519
to space at age forty seven, noted that while he
197
00:13:03.600 --> 00:13:06.080
has some creaks and groans in his body, he feels
198
00:13:06.120 --> 00:13:08.559
much the same as he did twenty years ago. The
199
00:13:08.559 --> 00:13:11.519
most challenging aspect of returning to Earth isn't the strain
200
00:13:11.559 --> 00:13:15.039
on major muscle groups, but rather the smaller muscles that
201
00:13:15.080 --> 00:13:19.679
go unused during extended periods in microgravity. A week ago,
202
00:13:19.799 --> 00:13:22.840
I was on station doing really heavy squats and dead lifts.
203
00:13:23.360 --> 00:13:26.039
I could float around with the greatest of ease, even
204
00:13:26.080 --> 00:13:28.919
though I had no trapezes. I was at the peak
205
00:13:29.000 --> 00:13:31.639
of my game, Pettit explained, and then you come back
206
00:13:31.679 --> 00:13:33.360
to Earth and it's like I can't even get up
207
00:13:33.399 --> 00:13:37.799
from the floor anymore. It's humbling. Interestingly, Pettit found that
208
00:13:37.879 --> 00:13:41.200
microgravity actually provided relief from some of the typical aches
209
00:13:41.240 --> 00:13:45.080
and pains associated with aging. I love being in space.
210
00:13:45.679 --> 00:13:48.399
When you're sleeping, you're just floating, and your body all
211
00:13:48.399 --> 00:13:50.919
those little aches and pains hel up. You feel like
212
00:13:50.919 --> 00:13:53.240
you're thirty years old again and free of pain, free
213
00:13:53.279 --> 00:13:56.799
of everything. Having visited the space station on all four
214
00:13:56.799 --> 00:14:00.559
of his space flights, Pettit expressed strong sentiments about NASA's
215
00:14:00.600 --> 00:14:03.799
plans to deorbit the facility in twenty thirty. I'm a
216
00:14:03.799 --> 00:14:05.799
firm believer we don't need to dump the space station
217
00:14:05.879 --> 00:14:08.039
in the ocean if we don't want to, he said,
218
00:14:08.519 --> 00:14:11.399
comparing the potential longevity of the ISS to that of
219
00:14:11.480 --> 00:14:14.240
the B fifty two bomber, which will have been flying
220
00:14:14.279 --> 00:14:17.960
for nearly a century before retirement. As for his own
221
00:14:18.000 --> 00:14:21.879
future in space exploration, Pettit hasn't ruled out another mission.
222
00:14:22.559 --> 00:14:24.480
When the flight docs say I'm ready to go back,
223
00:14:24.639 --> 00:14:26.960
I'm ready to do it. John Glenn flew at age
224
00:14:26.960 --> 00:14:29.200
seventy six, and I'm only seventy, so I've got a
225
00:14:29.240 --> 00:14:31.960
few more good years left. I could see getting another
226
00:14:32.000 --> 00:14:33.919
flight or two in before I'm ready to hang up
227
00:14:33.919 --> 00:14:38.720
my rocket nozzles. Pettitt described what he calls the explorer's paradox.
228
00:14:39.399 --> 00:14:43.440
When you're in civilization, you long for wilderness, When in
229
00:14:43.440 --> 00:14:46.639
the wilderness you miss your family. It's a sentiment that
230
00:14:46.679 --> 00:14:50.159
has likely existed for as long as humanity has had
231
00:14:50.200 --> 00:14:53.679
people who go off into the wilderness, and one that
232
00:14:53.799 --> 00:15:00.240
captures the unique calling of those who venture beyond our atmosphere. Well,
233
00:15:00.240 --> 00:15:03.639
that wraps up another fascinating episode of Astronomy Daily. From
234
00:15:03.720 --> 00:15:06.799
NASA's Roman Space Telescope with its panoramic view of space
235
00:15:06.840 --> 00:15:09.960
one hundred times greater than Hubble, to Amazon launching the
236
00:15:10.000 --> 00:15:14.279
first satellites in its massive project Kuyper Internet Constellation. We've
237
00:15:14.320 --> 00:15:17.919
explored ESA's groundbreaking biomass satellite that will help us understand
238
00:15:17.919 --> 00:15:21.759
forest carbon storage like never before, and China's potential first
239
00:15:21.759 --> 00:15:25.879
overseas launch site in Malaysia which could revolutionize equatorial launches.
240
00:15:26.519 --> 00:15:30.320
And who could forget astronaut Don Pettitt celebrating his seventieth
241
00:15:30.360 --> 00:15:33.759
birthday with perhaps the most dramatic return to Earth imaginable.
242
00:15:34.440 --> 00:15:37.679
Thanks so much for joining me today. I'm Anna, and
