on the stars. We'll start off with the highly anticipated
7
00:00:19.320 --> 00:00:23.000
annular solar eclipse, set to occur on October two, twenty
8
00:00:23.039 --> 00:00:25.960
twenty four, and explore the best spots to catch a
9
00:00:25.960 --> 00:00:29.600
glimpse of this stunning event. Next, we'll take a closer
10
00:00:29.640 --> 00:00:33.000
look at Boeing Starliner Calypso's recent undocking from the International
11
00:00:33.079 --> 00:00:36.479
Space Station and discuss the upcoming crew changes. We'll also
12
00:00:36.560 --> 00:00:39.799
unravel the mystery behind China's space plane, which has just
13
00:00:39.840 --> 00:00:42.799
returned from an impressive two hundred and sixty eight day mission.
14
00:00:43.359 --> 00:00:46.920
But that's not all. We'll delve into humanity's enduring fascination
15
00:00:47.000 --> 00:00:50.320
with aliens, tracing their impact on our culture and imagination
16
00:00:50.439 --> 00:00:53.799
from ancient times to the present. Finally, we'll talk about
17
00:00:53.880 --> 00:00:56.920
NASA's upcoming Roman Space Telescope and how it promises to
18
00:00:57.000 --> 00:01:01.159
revolutionize our understanding of galactic formation and dark matter. So
19
00:01:01.200 --> 00:01:05.120
sit back, relax, and let's embark on this celestial voyage together.
20
00:01:05.200 --> 00:01:09.120
On Astronomy Daily. One of the most exciting upcoming astronomical
21
00:01:09.159 --> 00:01:13.000
events is the annular solar eclipse on October two, twenty
22
00:01:13.040 --> 00:01:16.480
twenty four. This event promises to be a spectacular site
23
00:01:16.519 --> 00:01:18.599
for those fortunate enough to be in the right place
24
00:01:18.640 --> 00:01:20.959
at the right time, now for those who might be
25
00:01:21.040 --> 00:01:23.840
unfamiliar and annular eclipse occurs when the Moon is too
26
00:01:23.879 --> 00:01:26.719
far from the Earth to completely cover the Sun. This
27
00:01:26.799 --> 00:01:30.040
results in a breathtaking ring of fire effect, where the
28
00:01:30.159 --> 00:01:32.640
edges of the Sun remain visible as a luminous ring
29
00:01:32.719 --> 00:01:35.439
around the Moon's silhouette. Think of it as a celestial
30
00:01:35.439 --> 00:01:37.879
penny on top of a nickel. The last time we
31
00:01:37.959 --> 00:01:42.079
experienced such an eclipse was on October fourteenth, twenty twenty three,
32
00:01:42.599 --> 00:01:45.040
when it graced the skies over parts of the western
33
00:01:45.079 --> 00:01:49.680
and southern United States, the Yucatan Peninsula, Central America, and
34
00:01:49.719 --> 00:01:52.920
parts of South America. Millions were thrilled by the sight
35
00:01:53.000 --> 00:01:56.120
of the blazing ring of sunlight. However, if you thought
36
00:01:56.200 --> 00:01:59.560
last year's event was stunning, this year's eclipse presents an
37
00:01:59.719 --> 00:02:04.079
entirely different challenge and opportunity. Why you ask well. The
38
00:02:04.120 --> 00:02:07.640
path of this annular eclipse will mostly traverse open ocean waters,
39
00:02:08.080 --> 00:02:12.280
making landfall in only a few select locations. Approximately ninety
40
00:02:12.280 --> 00:02:14.400
five percent of the eclipses path will be over the
41
00:02:14.479 --> 00:02:17.840
vast expanses of the Pacific. This will make accessing the
42
00:02:17.879 --> 00:02:21.360
prime viewing spots more challenging compared to last year's easily
43
00:02:21.400 --> 00:02:25.360
accessible locations. The eclipse will begin over a remote area
44
00:02:25.479 --> 00:02:29.479
in the Central Pacific, roughly one thousand miles southwest of Honolulu.
45
00:02:29.840 --> 00:02:32.560
From there, it will move eastward and southeastward across the
46
00:02:32.599 --> 00:02:35.960
South Pacific. The path skirts just north of Kurebody, then
47
00:02:36.000 --> 00:02:39.719
continues northeast of French Polynesia and the Pitcairn Islands. The
48
00:02:39.800 --> 00:02:42.560
point of greatest eclipse, where the annular phase will last
49
00:02:42.560 --> 00:02:46.039
in impressive seven minutes and twenty four seconds, occurs over
50
00:02:46.080 --> 00:02:49.560
the open ocean, with the eclipse path approximately one sixty
51
00:02:49.560 --> 00:02:53.680
five miles wide. Yet there's a silver lining for eclipse enthusiasts.
52
00:02:54.000 --> 00:02:56.919
One of the most fascinating and remote locations to witness
53
00:02:56.960 --> 00:03:00.280
this event is the legendary Easter Island, also known as
54
00:03:00.360 --> 00:03:04.080
Rapa Nui. This UNESCO World Heritage Site famous for its
55
00:03:04.199 --> 00:03:08.520
enigmatic Moi statues carved from volcanic rock, lies almost directly
56
00:03:08.560 --> 00:03:11.319
in the path of the eclipse. If the weather permits,
57
00:03:11.759 --> 00:03:14.879
both the island's residence and visiting tourists will be treated
58
00:03:14.919 --> 00:03:19.120
to a remarkable display. Easter Island isn't just an archaeological wonder.
59
00:03:19.400 --> 00:03:22.400
It offers a unique vantage point for the eclipse. As
60
00:03:22.439 --> 00:03:24.960
the moon begins its journey across the Sun's disk at
61
00:03:25.000 --> 00:03:28.759
eleven twenty three am Local time, by one oh four pm,
62
00:03:28.840 --> 00:03:31.919
an off centered solar ring will emerge, lasting for about
63
00:03:31.919 --> 00:03:34.879
six minutes and five seconds. Following the peak, the moon
64
00:03:34.879 --> 00:03:37.680
will continue to move away, concluding its celestial dance at
65
00:03:37.680 --> 00:03:41.199
two fifty two PM. While an annular eclipse is undoubtedly
66
00:03:41.240 --> 00:03:44.479
an extraordinary sight, it's crucial to remember that it differs
67
00:03:44.520 --> 00:03:48.080
significantly from a total eclipse. During a total eclipse, the
68
00:03:48.080 --> 00:03:52.080
sky darkens dramatically, resembling twilight, and the Sun's corona becomes visible,
69
00:03:52.479 --> 00:03:56.680
offering a truly awe inspiring view. However, during an annular eclipse,
70
00:03:56.800 --> 00:03:59.280
the sky only dims slightly, and the bright ring of
71
00:03:59.280 --> 00:04:03.080
sunlight still makes direct viewing dangerous to the naked eye. Therefore,
72
00:04:03.240 --> 00:04:06.840
proper eye protection is essential throughout the event. The eclipse
73
00:04:06.840 --> 00:04:09.800
will also be partially visible at sunrise from the Hawaiian
74
00:04:09.800 --> 00:04:14.159
Islands and in the afternoon across southern South America. In Honolulu,
75
00:04:14.199 --> 00:04:16.959
for instance, the eclipse will reach its maximum phase at
76
00:04:16.959 --> 00:04:20.279
six forty five am local time, with fifty eight point
77
00:04:20.360 --> 00:04:22.720
six percent of the Sun's disc covered by the moon.
78
00:04:23.199 --> 00:04:26.639
Looking ahead, there's more celestial excitement on the horizon. On
79
00:04:26.680 --> 00:04:30.360
March twenty ninth, twenty twenty five, a partial solar eclipse
80
00:04:30.399 --> 00:04:35.000
will be visible across much of Europe, Northwest Africa, Greenland, Iceland,
81
00:04:35.279 --> 00:04:38.360
and parts of Atlantic Canada and New England. And mark
82
00:04:38.399 --> 00:04:42.319
your calendars for August twelfth, twenty twenty six, when the
83
00:04:42.319 --> 00:04:46.240
next total eclipse will sweep through eastern Greenland, western Iceland
84
00:04:46.519 --> 00:04:49.160
and northern Spain. For those of you planning to view
85
00:04:49.199 --> 00:04:53.000
the eclipse this October, whether from mainland South America or
86
00:04:53.040 --> 00:04:56.360
the mystical Easter Island, be sure to secure your protective
87
00:04:56.399 --> 00:05:00.800
eyewear and prepare for one of nature's most mesmerizing displays. Now,
88
00:05:00.879 --> 00:05:03.480
let's take a look at today's major event. The Boeing
89
00:05:03.519 --> 00:05:07.240
starliner Calypso has returned to Earth after its highly anticipated
90
00:05:07.319 --> 00:05:11.120
undocking from the International Space Station. This event marks a
91
00:05:11.160 --> 00:05:15.240
significant milestone in modern space exploration. Originally launched to the
92
00:05:15.279 --> 00:05:19.600
ISS on June fifth with two veteran astronauts Butch Wilmore
93
00:05:19.639 --> 00:05:22.800
and Sunny Williams, Calypso is now set to complete its
94
00:05:22.839 --> 00:05:25.959
mission back on Earth while Wilmore and Williams remain on
95
00:05:26.000 --> 00:05:29.879
the ISS for an additional six months. The autonomous undocking
96
00:05:29.920 --> 00:05:33.120
went smoothly at six oh four pm EDT on September sixth,
97
00:05:33.199 --> 00:05:36.240
right on schedule. Landing was slated for later that evening
98
00:05:36.240 --> 00:05:39.319
at White Sands in New Mexico, a familiar site for
99
00:05:39.399 --> 00:05:43.800
the Starliner's previous uncrude landings. White Sands Missile Range, known
100
00:05:43.839 --> 00:05:46.759
for its remarkable gypsum sand dunes, serves as one of
101
00:05:46.759 --> 00:05:50.439
the primary landing spots for the Starliner, alongside other options
102
00:05:50.480 --> 00:05:53.680
like Dugway Proving Ground in Utah and Wilcox Plane in Arizona.
103
00:05:54.120 --> 00:05:56.519
There's even a contingency site at Edward's Air Force Base
104
00:05:56.560 --> 00:06:01.079
in California. For this mission, the White Sands Harbor was
105
00:06:01.120 --> 00:06:04.800
the designated landing site, a location historical for hosting the
106
00:06:04.879 --> 00:06:08.560
landing of Space Shuttle Columbia in nineteen eighty two. Starliner
107
00:06:08.600 --> 00:06:12.279
Calypso has landed here before, notably following the orbital flight
108
00:06:12.319 --> 00:06:15.959
test mission in December twenty nineteen and the second uncrewed
109
00:06:16.040 --> 00:06:19.399
off two mission in May twenty twenty two. However, the
110
00:06:19.480 --> 00:06:21.759
landscape of the mission this time was different in a
111
00:06:21.800 --> 00:06:26.040
major way. It was uncrewed during this return. This landmark
112
00:06:26.079 --> 00:06:28.240
event has set the stage for what lies ahead in
113
00:06:28.279 --> 00:06:31.920
the tapestry of space missions. Just a week before undocking,
114
00:06:31.959 --> 00:06:35.240
on August twenty ninth, NASA completed part two of its
115
00:06:35.319 --> 00:06:39.480
readiness review, giving the green light for Calypso's uncrewed undocking
116
00:06:39.480 --> 00:06:42.800
from the MISS seven data loads were updated and the
117
00:06:42.800 --> 00:06:46.720
CFT software had shown excellent results during testing. Final checks
118
00:06:46.720 --> 00:06:49.439
wrapped up on September fifth with a readiness poll, and
119
00:06:49.480 --> 00:06:52.199
by one thirty pm EDT, the hatch was closed by
120
00:06:52.240 --> 00:06:56.560
Wilmore and Williams. Weather conditions were favorable, with winds clocked
121
00:06:56.560 --> 00:06:59.600
at seven to ten knots, a crucial element for ensuring
122
00:06:59.600 --> 00:07:03.079
a safe landing if the weather had not cooperated. Backup
123
00:07:03.160 --> 00:07:05.519
dates were lined up for the undocking on a four
124
00:07:05.600 --> 00:07:09.680
day cadence through September. The undocking started by releasing Calypso
125
00:07:09.759 --> 00:07:12.839
from the forward docking port on the ISS's harmony module.
126
00:07:13.360 --> 00:07:16.480
Unique to this procedure, a breakout burn using twelve thruster
127
00:07:16.560 --> 00:07:20.279
firings quickly pushed the spacecraft away from the ISS. This
128
00:07:20.399 --> 00:07:23.680
maneuver took about ninety seconds, helping to minimize stress on
129
00:07:23.720 --> 00:07:27.399
the thrusters. Once free of the station, additional tests on
130
00:07:27.439 --> 00:07:30.639
Calypso's thrusters were carried out to collect valuable data for
131
00:07:30.720 --> 00:07:34.199
NASA and Boeing aimed at solving the propulsion issues that
132
00:07:34.240 --> 00:07:38.480
have shadowed previous crude returns. Calypso's deorbit burn was conducted
133
00:07:38.480 --> 00:07:41.680
over the Pacific Ocean at eleven seventeen pm EDT on
134
00:07:41.759 --> 00:07:45.079
September sixth, setting it on a trajectory for White Sands.
135
00:07:45.519 --> 00:07:49.439
Communication blackout occurred due to ionized air around the spacecraft
136
00:07:49.560 --> 00:07:53.319
during re entry. Calypso flew over Baja California and Western
137
00:07:53.319 --> 00:07:57.000
Mexico before making its final approach to New Mexico. Upon
138
00:07:57.040 --> 00:08:00.000
nearing White Sands, the spacecraft jettisoned its forward heat shield
139
00:08:00.319 --> 00:08:03.879
and parachutes deployed in succession. Air bags inflated at about
140
00:08:03.879 --> 00:08:07.240
one kilometer above the ground, ensuring a soft nighttime touchdown.
141
00:08:07.800 --> 00:08:11.319
Following touchdown, the cargo was unloaded and preparations began to
142
00:08:11.360 --> 00:08:15.839
safely transport the spacecraft back to Boeing for future missions. Meanwhile,
143
00:08:16.160 --> 00:08:19.600
NASA and Boeing scientists scrutinized telemetry data to further understand
144
00:08:19.639 --> 00:08:23.680
the spacecraft's performance and refine future missions. The space community's
145
00:08:23.680 --> 00:08:27.360
eyes now turn to upcoming crew changes. Soyu's MS twenty
146
00:08:27.399 --> 00:08:30.040
six will launch on September eleventh, bringing a fresh team
147
00:08:30.040 --> 00:08:33.279
to the ISS and prompting a crew handover. This prompts
148
00:08:33.320 --> 00:08:37.480
the return of Soyu's MS twenty five on September twenty fourth. Additionally,
149
00:08:37.519 --> 00:08:40.879
the revised Crew nine mission using Crew Dragon Freedom will begin,
150
00:08:41.399 --> 00:08:44.559
adding yet another layer to the complex staffing of the ISS.
151
00:08:45.039 --> 00:08:48.080
The future looks bright for the Starliner, which is anticipated
152
00:08:48.080 --> 00:08:51.120
to take on its first operational mission, star Liner one,
153
00:08:51.360 --> 00:08:54.480
in February twenty twenty five. There are still some hurdles
154
00:08:54.480 --> 00:08:58.600
to clear, particularly with the spacecraft's propulsion system, but the
155
00:08:58.639 --> 00:09:02.600
ambition remains clear to continue pushing the frontiers of what's
156
00:09:02.679 --> 00:09:06.120
possible in space travel. In other notable space news today,
157
00:09:06.559 --> 00:09:09.759
China's mysterious space plane has captured global attention once again,
158
00:09:10.200 --> 00:09:12.720
having just completed an impressive two hundred and sixty eight
159
00:09:12.799 --> 00:09:16.519
day mission in orbit. This reusable spacecraft touched down at
160
00:09:16.559 --> 00:09:20.399
the Juquan Satellite Launch Center in northwest China on September sixth,
161
00:09:20.759 --> 00:09:24.759
marking yet another significant milestone in the realm of space exploration.
162
00:09:25.360 --> 00:09:28.759
Launched on December fourteenth, twenty twenty three, atop a long
163
00:09:28.799 --> 00:09:32.320
March two F rocket, this was the space plane's third mission,
164
00:09:32.840 --> 00:09:36.960
yet much about its capabilities and objectives remained shrouded in secrecy.
165
00:09:37.320 --> 00:09:40.720
According to Chinese state media outlet Xinhua, the mission was
166
00:09:40.759 --> 00:09:44.159
a stepping stone towards developing more convenient and affordable round
167
00:09:44.159 --> 00:09:48.360
trip methods for peaceful space utilization in the future. During
168
00:09:48.360 --> 00:09:52.000
its extended sojourn in orbit, the space plane reportedly performed
169
00:09:52.120 --> 00:09:56.440
various rendezvous and proximity operations, even releasing a small object
170
00:09:56.519 --> 00:10:00.399
into orbit, activities that could either serve satellite maintenance or
171
00:10:00.519 --> 00:10:05.559
pose potential implications for future orbital defense strategies. Astronomer Jonathan
172
00:10:05.600 --> 00:10:08.759
McDowell noted that this object was likely a sub satellite
173
00:10:08.799 --> 00:10:12.720
deployment or a piece of hardware ejected before mission end,
174
00:10:13.240 --> 00:10:17.320
paralleling the spacecraft's first flight. As enigmatic as its purposes
175
00:10:17.360 --> 00:10:21.080
may be, the space plane's prolonged mission hasn't gone unnoticed.
176
00:10:21.639 --> 00:10:24.200
Its return only two days before the US Space Force's
177
00:10:24.240 --> 00:10:28.159
own reusable vehicle, the X thirty seven B, launched, adds
178
00:10:28.200 --> 00:10:31.240
another layer to the intrigue. The X thirty seven B,
179
00:10:31.759 --> 00:10:35.639
like its Chinese counterpart, holds its mission details close to
180
00:10:35.679 --> 00:10:38.840
the chest, though it's known to be an experimental platform
181
00:10:38.879 --> 00:10:43.080
for new technologies. This endeavor underscores China's commitment to its
182
00:10:43.120 --> 00:10:47.320
space ambitions, positioning itself alongside other spacefaring nations like the
183
00:10:47.440 --> 00:10:50.320
US and India, which is also working on a reusable
184
00:10:50.399 --> 00:10:54.559
orbital vehicle named Pushpack. As these countries push the boundaries
185
00:10:54.559 --> 00:10:59.039
of space travel, the technological advances and strategic capabilities they
186
00:10:59.080 --> 00:11:03.440
achieve and fundamentally alter the future of missions, both civilian
187
00:11:03.440 --> 00:11:06.440
and military, paving the way for an era where the
188
00:11:06.480 --> 00:11:11.039
cost and complexity of space missions are considerably reduced. When
189
00:11:11.039 --> 00:11:14.320
we hear the word aliens, various images might pop into
190
00:11:14.360 --> 00:11:17.720
our heads, little green beings with big eyes, flying saucers,
191
00:11:17.799 --> 00:11:20.919
or perhaps epic battles in space. But this fascination with
192
00:11:21.000 --> 00:11:25.000
extraterrestrial life isn't just a modern phenomenon. It stretches back
193
00:11:25.080 --> 00:11:29.159
thousands of years and has evolved profoundly over time. Interestingly,
194
00:11:29.480 --> 00:11:31.960
the roots of this cosmic curiosity can be traced back
195
00:11:32.000 --> 00:11:36.200
to ancient civilizations. The Greek philosopher Epicurus and the Roman
196
00:11:36.240 --> 00:11:40.879
poet Lucretius both speculated about other worlds. Lucian of Samosada,
197
00:11:41.039 --> 00:11:44.000
writing in the second century CE, took this a step
198
00:11:44.080 --> 00:11:48.120
further with a true story, a satire about inhabitants of
199
00:11:48.159 --> 00:11:51.840
the Sun and Moon fighting over Venus's colonization. Even the
200
00:11:51.840 --> 00:11:55.000
Catholic Church during the Middle Ages entertained the idea of
201
00:11:55.039 --> 00:11:59.120
extraterrestrial life, viewing it as another testament to God's omnipotence.
202
00:12:00.120 --> 00:12:03.399
Fast forward to sixteen eighty six, when French author Bernard
203
00:12:03.480 --> 00:12:07.279
le Bouvier de Fontenelle's Conversations on the Plurality of Worlds
204
00:12:07.759 --> 00:12:12.480
captivated audiences, contemplating the existence of other solar systems and
205
00:12:12.519 --> 00:12:16.000
the potential for other worlds teeming with life. This work
206
00:12:16.080 --> 00:12:19.279
ushered in a new era of scientific inquiry and imagination
207
00:12:19.320 --> 00:12:23.279
about the cosmos. By the eighteenth century, belief in extraterrestrial
208
00:12:23.320 --> 00:12:27.559
life became almost mainstream among the educated. This intellectual curiosity
209
00:12:27.559 --> 00:12:30.399
peaked with HG. Well's War of the Worlds in eighteen
210
00:12:30.480 --> 00:12:33.879
ninety seven, a novel that essentially mirrored the anxieties and
211
00:12:33.919 --> 00:12:36.960
fears of the British colonial era. The idea that martians
212
00:12:37.000 --> 00:12:41.360
could invade Earth tapped into existential concerns and entertained readers simultaneously.
213
00:12:42.000 --> 00:12:45.919
In the twentieth century, advancements in astronomy and space exploration
214
00:12:46.440 --> 00:12:50.480
rejuvenated interest in extraterrestrial life. From the Space Race to
215
00:12:50.799 --> 00:12:53.799
iconic movies like Close Encounters of the Third Kind and
216
00:12:53.919 --> 00:12:57.240
Invasion of the Body Snatchers, the topic of aliens became
217
00:12:57.279 --> 00:13:00.679
a fixture in popular culture. Who can forget the sensation
218
00:13:00.879 --> 00:13:04.240
caused by orson Well's nineteen thirty eight radio broadcast of
219
00:13:04.279 --> 00:13:07.879
War of the Worlds, which supposedly incited panic among listeners
220
00:13:07.879 --> 00:13:12.960
who believed they were hearing real news of an extraterrestrial invasion. Today,
221
00:13:13.000 --> 00:13:16.720
the fascination has mounted exponentially with each scientific discovery and
222
00:13:16.759 --> 00:13:21.639
technological advancement. Films like Alien Star Trek two thousand and one,
223
00:13:21.759 --> 00:13:24.679
A Space Odyssey, and TV shows such as The X
224
00:13:24.720 --> 00:13:28.559
Files continue to capture our imagination. But beyond the silver screen,
225
00:13:29.159 --> 00:13:32.600
serious scientific endeavors like the search for exoplanets and the
226
00:13:32.600 --> 00:13:35.919
study of potential microbial life on Mars keep our eyes
227
00:13:35.919 --> 00:13:39.519
glued to telescopes and space missions. Robert Smith, a space
228
00:13:39.600 --> 00:13:43.559
historian at the University of Alberta, encapsulates this enduring fascination well.
229
00:13:43.919 --> 00:13:46.919
He argues that aliens serve as a mirror reflecting our
230
00:13:46.960 --> 00:13:50.759
own fears, hopes, and curiosities about humanity. By studying how
231
00:13:50.840 --> 00:13:55.200
we conceptualize extraterrestrial life, we gain insight into our perspectives
232
00:13:55.200 --> 00:13:58.320
on existence, power, and what it means to be human. Yes,
233
00:13:58.720 --> 00:14:02.320
aliens have staked a permit claim on our imaginations, conquering
234
00:14:02.360 --> 00:14:05.360
every form of media and igniting an enduring debate both
235
00:14:05.399 --> 00:14:09.679
in academia and around dinner tables. This relentless curiosity is
236
00:14:09.720 --> 00:14:13.440
perhaps best summarized by Arthur C. Clarke's famous quote, two
237
00:14:13.559 --> 00:14:17.039
possibilities exist. Either we are alone in the universe or
238
00:14:17.080 --> 00:14:20.679
we are not. Both are equally terrifying. So as we
239
00:14:20.720 --> 00:14:23.320
gaze at the stars and dream of life beyond Earth,
240
00:14:23.919 --> 00:14:27.639
let's appreciate how this quest both mirrors and molds are civilization.
241
00:14:28.240 --> 00:14:32.200
Whether through science, philosophy, or popular culture, the search for
242
00:14:32.279 --> 00:14:36.240
extraterrestrial life continues to challenge and inspire us, driving us
1
00:00:00.280 --> 00:00:03.160
2
00:00:03.200 --> 00:00:07.080
