00:00:00.199 --> 00:00:02.230
welcome to astronomy daily I'm excited


00:00:02.240 --> 00:00:03.869
to bring you another packed episode of


00:00:03.879 --> 00:00:05.910
space and astronomy news we've got some


00:00:05.920 --> 00:00:07.389
incredible stories lined up for you


00:00:07.399 --> 00:00:09.669
today that showcase Humanity's ongoing


00:00:09.679 --> 00:00:11.990
exploration of the cosmos we'll start


00:00:12.000 --> 00:00:14.030
with an update on NASA's Parker solar


00:00:14.040 --> 00:00:15.750
probe's remarkable Christmas Eve


00:00:15.760 --> 00:00:17.830
achievement as it made its closest


00:00:17.840 --> 00:00:20.150
approach ever to our son while becoming


00:00:20.160 --> 00:00:23.269
the fastest human-made object in history


00:00:23.279 --> 00:00:24.910
then we'll explore China's ambitious


00:00:24.920 --> 00:00:27.870
plans for new rocket launches in 2025


00:00:27.880 --> 00:00:29.189
which could reshape their space


00:00:29.199 --> 00:00:30.550
capabilities


00:00:30.560 --> 00:00:32.510
we'll also dive into some fascinating


00:00:32.520 --> 00:00:35.229
research about icy worlds like Europa


00:00:35.239 --> 00:00:37.069
examine a recent software glitch that


00:00:37.079 --> 00:00:39.350
affected satellite Communications and


00:00:39.360 --> 00:00:41.549
look ahead to some spectacular celestial


00:00:41.559 --> 00:00:44.229
events coming our way the universe keeps


00:00:44.239 --> 00:00:46.630
surprising us with new discoveries and I


00:00:46.640 --> 00:00:48.670
can't wait to share them all with you


00:00:48.680 --> 00:00:50.470
let's get into today's


00:00:50.480 --> 00:00:53.510
news on Christmas Eve NASA's Parker


00:00:53.520 --> 00:00:55.590
solar probe achieved an extraordinary


00:00:55.600 --> 00:00:58.229
feat skimming closer to the Sun than any


00:00:58.239 --> 00:01:01.069
human-made object has ever ventured at


00:01:01.079 --> 00:01:03.630
precisely 6:53 a.m. eastern time on


00:01:03.640 --> 00:01:06.030
December 24th the spacecraft passed


00:01:06.040 --> 00:01:08.789
within just 6.1 million kilm of the


00:01:08.799 --> 00:01:10.789
sun's surface shattering its own


00:01:10.799 --> 00:01:14.109
previous record of 7.26 million kilm set


00:01:14.119 --> 00:01:17.109
earlier in 2023 but that wasn't the only


00:01:17.119 --> 00:01:19.310
record broken that day during its


00:01:19.320 --> 00:01:21.710
closest approach the probe became the


00:01:21.720 --> 00:01:24.310
fastest object ever created by humans


00:01:24.320 --> 00:01:27.350
reaching a mindboggling speed of 692


00:01:27.360 --> 00:01:28.429
th000


00:01:28.439 --> 00:01:30.590
kmph to put that that incredible


00:01:30.600 --> 00:01:33.069
velocity into perspective at that speed


00:01:33.079 --> 00:01:34.870
you could travel from Philadelphia to


00:01:34.880 --> 00:01:37.990
Washington DC in about 1 second this


00:01:38.000 --> 00:01:39.550
remarkable achievement marks the


00:01:39.560 --> 00:01:42.069
culmination of six years in space for


00:01:42.079 --> 00:01:44.749
the Parker solar probe since its launch


00:01:44.759 --> 00:01:47.149
in 2018 the spacecraft has been on a


00:01:47.159 --> 00:01:49.310
complex journey to study the sun's outer


00:01:49.320 --> 00:01:52.749
atmosphere or Corona from the inside due


00:01:52.759 --> 00:01:55.510
to the sun's powerful gravitational pole


00:01:55.520 --> 00:01:57.230
the probe couldn't simply fly straight


00:01:57.240 --> 00:01:59.950
to its destination instead it has been


00:01:59.960 --> 00:02:02.469
forming an intricate orbital dance using


00:02:02.479 --> 00:02:04.709
Venus's gravity to gradually adjust its


00:02:04.719 --> 00:02:07.270
path closer to the Sun through 21


00:02:07.280 --> 00:02:09.029
increasingly narrow


00:02:09.039 --> 00:02:11.470
flybys the mission reached a crucial


00:02:11.480 --> 00:02:14.270
Milestone on November 6th when the final


00:02:14.280 --> 00:02:16.270
Venus flyby positioned the probe into


00:02:16.280 --> 00:02:18.910
its optimal orbit this carefully


00:02:18.920 --> 00:02:20.550
calculated position allows the


00:02:20.560 --> 00:02:22.509
spacecraft to study the sun's processes


00:02:22.519 --> 00:02:24.750
up close while remaining just far enough


00:02:24.760 --> 00:02:27.150
away to avoid destruction during its


00:02:27.160 --> 00:02:29.030
closest approach the probe was


00:02:29.040 --> 00:02:30.670
completely out of cont with Earth for


00:02:30.680 --> 00:02:33.270
about a week the tension finally broke


00:02:33.280 --> 00:02:35.790
just before midnight on December 27th


00:02:35.800 --> 00:02:37.710
when scientists received a beacon signal


00:02:37.720 --> 00:02:39.470
confirming the spacecraft had survived


00:02:39.480 --> 00:02:42.670
its daring encounter 3 days later on New


00:02:42.680 --> 00:02:45.509
Year's Day more detailed data arrived


00:02:45.519 --> 00:02:47.670
showing the probe was healthy and had


00:02:47.680 --> 00:02:49.270
successfully collected scientific


00:02:49.280 --> 00:02:51.070
measurements during its record-breaking


00:02:51.080 --> 00:02:53.350
flyby Mission controllers must have


00:02:53.360 --> 00:02:56.270
breathed a huge sigh of relief the probe


00:02:56.280 --> 00:02:58.030
will maintain this new orbit for at


00:02:58.040 --> 00:03:00.030
least 9 months with two more more


00:03:00.040 --> 00:03:01.830
equally close passes planned for March


00:03:01.840 --> 00:03:04.229
and June before its primary Mission


00:03:04.239 --> 00:03:06.350
concludes in September


00:03:06.360 --> 00:03:09.030
2025 these repeated Close Encounters


00:03:09.040 --> 00:03:11.390
promised to reveal unprecedented details


00:03:11.400 --> 00:03:13.589
about our Stars behavior and help us


00:03:13.599 --> 00:03:15.430
better understand the forces that shape


00:03:15.440 --> 00:03:16.830
our solar


00:03:16.840 --> 00:03:20.030
system next up today udat recently


00:03:20.040 --> 00:03:21.869
reported a significant disruption to


00:03:21.879 --> 00:03:23.869
their one web satellite Network that


00:03:23.879 --> 00:03:26.509
left users without service for 2 days


00:03:26.519 --> 00:03:29.270
the outage which began on December 31st


00:03:29.280 --> 00:03:31.309
was traced back to a rather familiar


00:03:31.319 --> 00:03:33.429
culprit in the Computing World a


00:03:33.439 --> 00:03:35.470
leapyear software bug in their ground


00:03:35.480 --> 00:03:38.270
segment systems the timing couldn't have


00:03:38.280 --> 00:03:40.429
been more ironic as the system failed to


00:03:40.439 --> 00:03:42.789
properly account for 2024 being a leap


00:03:42.799 --> 00:03:45.229
year Services were only partially


00:03:45.239 --> 00:03:47.990
restored after 36 hours with full


00:03:48.000 --> 00:03:49.830
functionality returning shortly


00:03:49.840 --> 00:03:52.350
thereafter this incident highlights just


00:03:52.360 --> 00:03:54.229
how complex modern satellite networks


00:03:54.239 --> 00:03:56.630
are and how even seemingly simple


00:03:56.640 --> 00:03:58.069
oversights can have far-reaching


00:03:58.079 --> 00:03:59.949
consequences


00:03:59.959 --> 00:04:01.990
what makes this particularly noteworthy


00:04:02.000 --> 00:04:03.949
is that one web had just recently


00:04:03.959 --> 00:04:06.110
achieved the capability for worldwide


00:04:06.120 --> 00:04:07.550
coverage in


00:04:07.560 --> 00:04:09.830
2023 the company has been steadily


00:04:09.840 --> 00:04:11.830
working to expand its services across


00:04:11.840 --> 00:04:14.630
the Americas Europe and Asia with plans


00:04:14.640 --> 00:04:16.590
to launch full services for government


00:04:16.600 --> 00:04:19.030
and Enterprise customers including


00:04:19.040 --> 00:04:22.270
Aviation this spring the good news is


00:04:22.280 --> 00:04:24.749
that uat's multi-orbit capabilities


00:04:24.759 --> 00:04:26.629
should provide better Network resilience


00:04:26.639 --> 00:04:29.430
in the future the company operates both


00:04:29.440 --> 00:04:31.590
the one web constellation in low earth


00:04:31.600 --> 00:04:34.909
orbit and a fleet of 35 geostationary


00:04:34.919 --> 00:04:37.230
satellites this dual system approach is


00:04:37.240 --> 00:04:38.950
part of their strategy to compete with


00:04:38.960 --> 00:04:41.029
industry leader starlink allowing them


00:04:41.039 --> 00:04:42.909
to supplement one web services with


00:04:42.919 --> 00:04:45.629
geostationary capacity in high demand


00:04:45.639 --> 00:04:48.790
areas looking ahead udat isn't letting


00:04:48.800 --> 00:04:51.150
this setback slow their momentum they've


00:04:51.160 --> 00:04:53.029
already ordered 100 new oneweb


00:04:53.039 --> 00:04:55.390
satellites from Airbus defense in space


00:04:55.400 --> 00:04:57.110
to ensure the constellation remains


00:04:57.120 --> 00:04:59.230
robust as the current satellites reach


00:04:59.240 --> 00:05:02.510
the end of their design lives in 2027


00:05:02.520 --> 00:05:04.070
and


00:05:04.080 --> 00:05:06.670
2028 next we head on over to a country


00:05:06.680 --> 00:05:08.790
that's fast becoming a major space force


00:05:08.800 --> 00:05:11.550
to be reckoned with China is gearing up


00:05:11.560 --> 00:05:14.710
for an exciting year in space with 2025


00:05:14.720 --> 00:05:16.909
set to see the Deb of several new


00:05:16.919 --> 00:05:18.390
rockets from both state-owned


00:05:18.400 --> 00:05:20.870
Enterprises and Commercial companies


00:05:20.880 --> 00:05:22.550
these new launchers represent a


00:05:22.560 --> 00:05:24.790
significant Leap Forward in China's


00:05:24.800 --> 00:05:27.189
space capabilities particularly in the


00:05:27.199 --> 00:05:29.870
realm of reusable technology


00:05:29.880 --> 00:05:32.710
leading the charge is the Long March 8A


00:05:32.720 --> 00:05:34.950
an upgraded version of the existing Long


00:05:34.960 --> 00:05:37.309
March 8th rocket this new variant


00:05:37.319 --> 00:05:39.309
features a more powerful second stage


00:05:39.319 --> 00:05:41.550
that boosts its payload capacity to


00:05:41.560 --> 00:05:45.230
7,000 kg to Sun synchronous orbit what's


00:05:45.240 --> 00:05:46.830
particularly interesting is that they're


00:05:46.840 --> 00:05:50.950
incorporating a larger 5.2 Das meter Das


00:05:50.960 --> 00:05:53.070
diameter payload fairing giving them


00:05:53.080 --> 00:05:55.790
more flexibility for future missions


00:05:55.800 --> 00:05:57.830
another notable development is the Long


00:05:57.840 --> 00:06:00.230
March 12a which is taking a page from


00:06:00.240 --> 00:06:02.510
spacex's Playbook by implementing


00:06:02.520 --> 00:06:04.830
vertical takeoff and vertical Landing


00:06:04.840 --> 00:06:07.029
capabilities this marks China's first


00:06:07.039 --> 00:06:09.110
serious Venture into reusable rocket


00:06:09.120 --> 00:06:11.670
technology at the state level the


00:06:11.680 --> 00:06:13.950
commercial sector is equally ambitious


00:06:13.960 --> 00:06:16.230
landspace is preparing their juk 3


00:06:16.240 --> 00:06:18.150
rocket a massive stainless steel


00:06:18.160 --> 00:06:21.629
launcher that will stand 76 M tall in


00:06:21.639 --> 00:06:23.749
Expendable configuration it will be


00:06:23.759 --> 00:06:26.870
capable of lifting 21,000 kg to low


00:06:26.880 --> 00:06:30.870
earth orbit or 18,300 kg when recovering


00:06:30.880 --> 00:06:32.550
the first stage


00:06:32.560 --> 00:06:35.430
downrange this impressive capability


00:06:35.440 --> 00:06:37.230
puts it in direct competition with some


00:06:37.240 --> 00:06:39.469
of the most powerful Rockets currently


00:06:39.479 --> 00:06:41.550
operating we're also seeing several


00:06:41.560 --> 00:06:42.990
other commercial players entering the


00:06:43.000 --> 00:06:45.430
field Galactic energy is developing both


00:06:45.440 --> 00:06:48.070
the palace 1 designed for eventual


00:06:48.080 --> 00:06:50.710
reusability and the upgraded Series 2


00:06:50.720 --> 00:06:54.070
solid rocket cast space a spin-off from


00:06:54.080 --> 00:06:56.189
the Chinese Academy of Sciences is


00:06:56.199 --> 00:06:58.710
working on their kinetica 2 rocket which


00:06:58.720 --> 00:07:00.670
aims to serve China's growing commercial


00:07:00.680 --> 00:07:03.350
space sector these new rockets aren't


00:07:03.360 --> 00:07:05.790
just about showing technological prowess


00:07:05.800 --> 00:07:08.150
they serve a practical purpose they'll


00:07:08.160 --> 00:07:09.990
be competing for contracts to launch


00:07:10.000 --> 00:07:12.070
satellites for China's ambitious Mega


00:07:12.080 --> 00:07:14.350
constellation projects space station


00:07:14.360 --> 00:07:17.350
cargo missions and Commercial payloads


00:07:17.360 --> 00:07:19.029
this expansion and launch capabilities


00:07:19.039 --> 00:07:20.869
is essential for China's growing space


00:07:20.879 --> 00:07:22.950
program and could potentially attract


00:07:22.960 --> 00:07:24.790
International customers though


00:07:24.800 --> 00:07:26.670
geopolitical challenges remain a


00:07:26.680 --> 00:07:28.830
consideration the influx of new launch


00:07:28.840 --> 00:07:30.110
Vehicles particular particularly those


00:07:30.120 --> 00:07:32.390
incorporating reusability signals


00:07:32.400 --> 00:07:34.029
China's commitment to developing a


00:07:34.039 --> 00:07:36.510
robust and competitive space industry


00:07:36.520 --> 00:07:37.869
while some of these companies will be


00:07:37.879 --> 00:07:40.270
competing for limited domestic contracts


00:07:40.280 --> 00:07:42.189
the end result will likely be a more


00:07:42.199 --> 00:07:44.230
capable and cost- effective space launch


00:07:44.240 --> 00:07:45.629
sector for


00:07:45.639 --> 00:07:48.390
China exciting new research has emerged


00:07:48.400 --> 00:07:50.110
that could revolutionize our


00:07:50.120 --> 00:07:51.749
understanding of icy ocean worlds like


00:07:51.759 --> 00:07:54.390
Jupiter's moon Europa scientists have


00:07:54.400 --> 00:07:56.270
introduced a novel concept called the


00:07:56.280 --> 00:07:58.430
cotectic which helps us understand how


00:07:58.440 --> 00:08:00.149
liquid water can remain stable under


00:08:00.159 --> 00:08:02.270
extreme conditions on these Distant


00:08:02.280 --> 00:08:04.710
Worlds the research published in nature


00:08:04.720 --> 00:08:06.629
Communications comes from a fascinating


00:08:06.639 --> 00:08:08.629
collaboration between Dr Matt Powell


00:08:08.639 --> 00:08:12.430
Palm from Texas a andm university and


00:08:12.440 --> 00:08:15.270
planetary scientist Dr Baptist jerau


00:08:15.280 --> 00:08:17.950
from the University of Washington their


00:08:17.960 --> 00:08:20.230
work couldn't be more timely as NASA's


00:08:20.240 --> 00:08:22.189
Europa Clipper Mission prepares for its


00:08:22.199 --> 00:08:24.149
journey to Jupiter's mysterious ice


00:08:24.159 --> 00:08:26.629
covered moon but what exactly is the


00:08:26.639 --> 00:08:29.749
cotectic it's essentially the absolute


00:08:29.759 --> 00:08:31.629
temperature at which liquid water can


00:08:31.639 --> 00:08:33.990
remain stable under different pressures


00:08:34.000 --> 00:08:34.790
and


00:08:34.800 --> 00:08:36.589
concentrations think of it as a


00:08:36.599 --> 00:08:38.909
thermodynamic boundary that helps us


00:08:38.919 --> 00:08:40.829
determine where liquid water might exist


00:08:40.839 --> 00:08:43.149
on these icy moons even under seemingly


00:08:43.159 --> 00:08:45.870
impossible conditions what makes this


00:08:45.880 --> 00:08:47.670
research particularly intriguing is how


00:08:47.680 --> 00:08:50.269
it Bridges two very different fields


00:08:50.279 --> 00:08:53.150
Powell Palm's expertise in cryobiology


00:08:53.160 --> 00:08:54.670
originally focused on medical


00:08:54.680 --> 00:08:56.910
applications like organ preservation


00:08:56.920 --> 00:08:59.030
combines with J's knowledge of planetary


00:08:59.040 --> 00:09:00.790
science to create a powerful new


00:09:00.800 --> 00:09:03.430
framework for understanding these alien


00:09:03.440 --> 00:09:06.030
environments with NASA's Europa Clipper


00:09:06.040 --> 00:09:07.870
Mission representing the largest


00:09:07.880 --> 00:09:09.670
Planetary Exploration Mission ever


00:09:09.680 --> 00:09:11.990
launched This research couldn't come at


00:09:12.000 --> 00:09:14.470
a better time the mission will help us


00:09:14.480 --> 00:09:16.269
understand how deep europa's ocean is


00:09:16.279 --> 00:09:18.910
and what it's made of when combined with


00:09:18.920 --> 00:09:20.670
these new laboratory findings about


00:09:20.680 --> 00:09:22.949
liquid stability we'll be able to better


00:09:22.959 --> 00:09:25.069
assess just how habitable these cold


00:09:25.079 --> 00:09:27.710
deep oceans might be the implications


00:09:27.720 --> 00:09:30.190
are profound this research doesn't just


00:09:30.200 --> 00:09:32.509
help us understand Europa it could apply


00:09:32.519 --> 00:09:34.590
to numerous other icy worlds throughout


00:09:34.600 --> 00:09:36.910
our solar system as we continue to


00:09:36.920 --> 00:09:38.790
search for potential habitats for life


00:09:38.800 --> 00:09:40.750
beyond Earth understanding these


00:09:40.760 --> 00:09:42.550
fundamental properties of water under


00:09:42.560 --> 00:09:45.150
extreme conditions becomes increasingly


00:09:45.160 --> 00:09:47.630
crucial this work represents another


00:09:47.640 --> 00:09:49.990
step forward in our quest to understand


00:09:50.000 --> 00:09:52.069
these fascinating worlds and their


00:09:52.079 --> 00:09:54.630
potential to Harbor life demonstrating


00:09:54.640 --> 00:09:56.910
how breakthroughs in seemingly unrelated


00:09:56.920 --> 00:09:59.470
Fields can come together to unlock the


00:09:59.480 --> 00:10:02.150
mysteries of our Cosmic


00:10:02.160 --> 00:10:04.190
neighborhood now something to look


00:10:04.200 --> 00:10:06.310
forward to space enthusiasts and


00:10:06.320 --> 00:10:09.269
skywatchers are in for a treat in 2025


00:10:09.279 --> 00:10:11.509
with four spectacular eclipses on the


00:10:11.519 --> 00:10:13.750
calendar while we won't see any total


00:10:13.760 --> 00:10:15.790
solar eclipses this year we'll be


00:10:15.800 --> 00:10:18.350
treated to two total lunar eclipses


00:10:18.360 --> 00:10:20.990
something we haven't experienced since


00:10:21.000 --> 00:10:23.389
2022 the first major event comes on


00:10:23.399 --> 00:10:25.829
March 14th with a total lunar eclipse


00:10:25.839 --> 00:10:27.590
that's perfectly timed for viewers


00:10:27.600 --> 00:10:29.829
across North and South America


00:10:29.839 --> 00:10:31.389
if you're in the contiguous United


00:10:31.399 --> 00:10:33.750
States Mexico or Canada you'll be able


00:10:33.760 --> 00:10:35.990
to witness the entire show from the


00:10:36.000 --> 00:10:37.870
first Shadow crossing the moon's face to


00:10:37.880 --> 00:10:40.470
the last during totality which lasts for


00:10:40.480 --> 00:10:43.110
66 minutes keep an eye on the moon's


00:10:43.120 --> 00:10:45.350
Northern Edge it should appear slightly


00:10:45.360 --> 00:10:46.870
brighter than the rest of the shadowed


00:10:46.880 --> 00:10:50.069
disc 2 weeks later on March 29th we'll


00:10:50.079 --> 00:10:51.910
see the year's first partial solar


00:10:51.920 --> 00:10:54.150
eclipse while Europe and northwest


00:10:54.160 --> 00:10:56.190
Africa will get a good view the best


00:10:56.200 --> 00:10:58.470
location will actually be in Quebec near


00:10:58.480 --> 00:11:00.829
Hudson Bay where observers can witness


00:11:00.839 --> 00:11:04.150
up to 93% of the sun's disc covered at


00:11:04.160 --> 00:11:06.470
sunrise September brings our second pair


00:11:06.480 --> 00:11:08.790
of eclipses starting with another total


00:11:08.800 --> 00:11:11.670
lunar eclipse on the 7th this one favors


00:11:11.680 --> 00:11:13.750
the Eastern Hemisphere making it a


00:11:13.760 --> 00:11:15.590
perfect evening show for Europe and


00:11:15.600 --> 00:11:18.030
Africa while Asia and Australia will


00:11:18.040 --> 00:11:19.870
catch it in the early morning hours of


00:11:19.880 --> 00:11:22.550
September 8th the eclipse's totality


00:11:22.560 --> 00:11:25.590
will last an impressive 82 minutes the


00:11:25.600 --> 00:11:27.710
year's final eclipse occurs on September


00:11:27.720 --> 00:11:30.590
21st with a part solar eclipse that will


00:11:30.600 --> 00:11:32.430
be primarily visible from the South


00:11:32.440 --> 00:11:35.150
Pacific and southern oceans New Zealand


00:11:35.160 --> 00:11:37.590
will get the best populated area view


00:11:37.600 --> 00:11:40.829
with up to 73% of the sun's dis covered


00:11:40.839 --> 00:11:42.590
from the country's Southern


00:11:42.600 --> 00:11:44.670
regions while this might seem like a


00:11:44.680 --> 00:11:47.230
relatively quiet year for eclipses it's


00:11:47.240 --> 00:11:49.790
setting us up for some truly spectacular


00:11:49.800 --> 00:11:50.949
events in


00:11:50.959 --> 00:11:54.069
2026 including a total solar eclipse


00:11:54.079 --> 00:11:56.829
visible from Spain in August something


00:11:56.839 --> 00:11:58.910
Eclipse Chasers are already eagerly


00:11:58.920 --> 00:12:00.829
