00:00:00.160 --> 00:00:01.949
today we have a great lineup of stories


00:00:01.959 --> 00:00:04.030
from across the cosmos that showcase


00:00:04.040 --> 00:00:06.110
just how Dynamic and fascinating our


00:00:06.120 --> 00:00:09.350
universe truly is from ancient Martian


00:00:09.360 --> 00:00:12.190
beaches that hint at a watery past to


00:00:12.200 --> 00:00:13.990
cuttingedge discoveries in quantum


00:00:14.000 --> 00:00:15.910
physics that could revolutionize our


00:00:15.920 --> 00:00:17.590
understanding of gravity we're covering


00:00:17.600 --> 00:00:20.150
the full spectrum of Space Science we'll


00:00:20.160 --> 00:00:21.590
dive into the latest findings from


00:00:21.600 --> 00:00:24.109
China's Jang Rover that's uncovered


00:00:24.119 --> 00:00:25.830
compelling evidence of ancient ocean


00:00:25.840 --> 00:00:28.710
shorelines on Mars explore spacex's


00:00:28.720 --> 00:00:30.109
completed investigation into to


00:00:30.119 --> 00:00:32.389
January's Starship test flight and look


00:00:32.399 --> 00:00:34.190
ahead at an incredibly busy week of


00:00:34.200 --> 00:00:36.790
space launches we'll also examine a


00:00:36.800 --> 00:00:38.310
powerful solar flare that recently


00:00:38.320 --> 00:00:40.190
triggered radio blackouts and discussed


00:00:40.200 --> 00:00:41.709
groundbreaking new research that


00:00:41.719 --> 00:00:43.910
suggests gravitational waves might have


00:00:43.920 --> 00:00:46.430
Quantum properties get ready for a


00:00:46.440 --> 00:00:47.590
journey through some of the most


00:00:47.600 --> 00:00:49.229
exciting developments in space


00:00:49.239 --> 00:00:50.709
exploration and


00:00:50.719 --> 00:00:52.750
astronomy let's get started with news


00:00:52.760 --> 00:00:53.990
from our neighbor that keeps on


00:00:54.000 --> 00:00:57.029
surprising us fascinating news from the


00:00:57.039 --> 00:01:00.349
red planet today as China's zurong Rover


00:01:00.359 --> 00:01:02.509
has uncovered compelling evidence of


00:01:02.519 --> 00:01:04.710
what appears to be ancient beaches


00:01:04.720 --> 00:01:07.109
buried beneath the Martian surface the


00:01:07.119 --> 00:01:09.070
Rover's ground penetrating radar


00:01:09.080 --> 00:01:10.990
detected structures that strongly


00:01:11.000 --> 00:01:13.550
resemble Earth's Coastal deposits


00:01:13.560 --> 00:01:15.950
suggesting the presence of a vast ocean


00:01:15.960 --> 00:01:19.109
on Mars approximately 3.5 to 4 billion


00:01:19.119 --> 00:01:21.950
years ago the data reveals layers of


00:01:21.960 --> 00:01:24.390
material similar to sand buried between


00:01:24.400 --> 00:01:27.910
10 and 35 M underground these layers are


00:01:27.920 --> 00:01:30.350
all sloped in the same direction and at


00:01:30.360 --> 00:01:32.270
Angles matching those found on Earth's


00:01:32.280 --> 00:01:35.190
beaches where the sea meets the land the


00:01:35.200 --> 00:01:37.469
structures span an impressive 1.2


00:01:37.479 --> 00:01:39.870
kilometers along the Rover's path in the


00:01:39.880 --> 00:01:42.789
Utopia plena region according to


00:01:42.799 --> 00:01:44.910
scientists these Beach deposits would


00:01:44.920 --> 00:01:47.350
have taken millions of years to form


00:01:47.360 --> 00:01:49.429
indicating a long lived body of water


00:01:49.439 --> 00:01:51.550
with active waves and Tides much like


00:01:51.560 --> 00:01:54.230
Earth's oceans this ancient Martian


00:01:54.240 --> 00:01:56.830
ocean known as deuteronilus would have


00:01:56.840 --> 00:01:58.749
existed during a time when Mars had a


00:01:58.759 --> 00:02:01.230
thicker atmosphere and warmer climate


00:02:01.240 --> 00:02:02.990
conditions potentially suitable for life


00:02:03.000 --> 00:02:04.389
to emerge and


00:02:04.399 --> 00:02:06.510
Thrive what makes this discovery


00:02:06.520 --> 00:02:08.669
particularly significant is that while


00:02:08.679 --> 00:02:10.550
surface features suggesting ancient


00:02:10.560 --> 00:02:13.030
shorelines have been observed from orbit


00:02:13.040 --> 00:02:14.869
billions of years of wind erosion and


00:02:14.879 --> 00:02:17.710
geological processes have largely erased


00:02:17.720 --> 00:02:20.470
or distorted such evidence these newly


00:02:20.480 --> 00:02:22.470
found structures however have been


00:02:22.480 --> 00:02:23.869
beautifully preserved beneath the


00:02:23.879 --> 00:02:26.229
surface protected by layers of material


00:02:26.239 --> 00:02:28.630
deposited by dust storms meteorite


00:02:28.640 --> 00:02:31.710
impacts and Volcan iic activity the


00:02:31.720 --> 00:02:33.910
findings are especially intriguing for


00:02:33.920 --> 00:02:35.750
astrobiologists as shorelines are


00:02:35.760 --> 00:02:37.670
considered Prime locations to search for


00:02:37.680 --> 00:02:40.869
evidence of past life on Earth it's


00:02:40.879 --> 00:02:42.229
believed that life may have first


00:02:42.239 --> 00:02:44.430
emerged in similar environments where


00:02:44.440 --> 00:02:47.830
air water and land interact while this


00:02:47.840 --> 00:02:50.229
doesn't prove life existed on Mars it


00:02:50.239 --> 00:02:52.030
provides valuable insight into where


00:02:52.040 --> 00:02:53.949
future missions might Focus their search


00:02:53.959 --> 00:02:56.309
for potential bio signatures this


00:02:56.319 --> 00:02:58.550
groundbreaking discovery also suggests


00:02:58.560 --> 00:03:00.390
that significant amounts of Mars's


00:03:00.400 --> 00:03:03.390
ancient water may still exist today


00:03:03.400 --> 00:03:05.070
either lost to space or trapped


00:03:05.080 --> 00:03:07.509
underground in vast reservoirs as


00:03:07.519 --> 00:03:09.550
indicated by recent seismic data from


00:03:09.560 --> 00:03:12.509
NASA's Insight Lander the implications


00:03:12.519 --> 00:03:14.430
of these findings continue to reshape


00:03:14.440 --> 00:03:17.190
our understanding of Mars's Dynamic past


00:03:17.200 --> 00:03:19.750
and its potential to have once harbored


00:03:19.760 --> 00:03:22.589
life SpaceX has recently concluded its


00:03:22.599 --> 00:03:24.509
investigation into the dramatic end of


00:03:24.519 --> 00:03:26.589
starship's seventh test flight which


00:03:26.599 --> 00:03:28.750
occurred this past January the


00:03:28.760 --> 00:03:30.030
investigation revealed that the


00:03:30.040 --> 00:03:32.070
explosion was caused by an unexpected


00:03:32.080 --> 00:03:34.149
combination of factors primarily


00:03:34.159 --> 00:03:35.830
centered around harmonic resonance and


00:03:35.840 --> 00:03:38.030
propellant system issues according to


00:03:38.040 --> 00:03:40.229
spacex's findings the ship experienced


00:03:40.239 --> 00:03:42.190
harmonic vibrations several times


00:03:42.200 --> 00:03:43.750
stronger than what had been observed


00:03:43.760 --> 00:03:46.149
during ground testing these intense


00:03:46.159 --> 00:03:48.229
vibrations led to increased stress on


00:03:48.239 --> 00:03:49.509
critical components within the


00:03:49.519 --> 00:03:51.910
propulsion system ultimately resulting


00:03:51.920 --> 00:03:53.509
in propellent leaks that exceeded the


00:03:53.519 --> 00:03:55.910
vehicle safety parameters the leaking


00:03:55.920 --> 00:03:57.949
propellants accumulated in what SpaceX


00:03:57.959 --> 00:04:00.869
calls the attic an pressurized area


00:04:00.879 --> 00:04:02.830
located between the bottom of the liquid


00:04:02.840 --> 00:04:05.670
oxygen tank and the heat shield the


00:04:05.680 --> 00:04:07.470
situation quickly escalated as the


00:04:07.480 --> 00:04:09.069
propellent leaks overwhelmed the


00:04:09.079 --> 00:04:11.390
spacecraft's venting capabilities


00:04:11.400 --> 00:04:14.509
leading to sustained fires these fires


00:04:14.519 --> 00:04:16.590
caused all but one of starship's engines


00:04:16.600 --> 00:04:18.229
to initiate controlled shutdown


00:04:18.239 --> 00:04:20.590
sequences and eventually resulted in a


00:04:20.600 --> 00:04:22.510
complete loss of communication with the


00:04:22.520 --> 00:04:25.030
vehicle SpaceX has already implemented


00:04:25.040 --> 00:04:26.550
several improvements to address these


00:04:26.560 --> 00:04:28.950
issues for future flights the company


00:04:28.960 --> 00:04:31.390
conducted an extended 60-second static


00:04:31.400 --> 00:04:33.990
fire test with the ship that will fly on


00:04:34.000 --> 00:04:36.550
the upcoming eth Mission this testing


00:04:36.560 --> 00:04:38.230
has informed multiple Hardware


00:04:38.240 --> 00:04:40.270
modifications including changes to the


00:04:40.280 --> 00:04:42.590
fuel feed lines for vacuum engines


00:04:42.600 --> 00:04:44.790
adjustments to propellant temperatures


00:04:44.800 --> 00:04:46.670
and the establishment of new operating


00:04:46.680 --> 00:04:49.189
thrust targets to prevent similar issues


00:04:49.199 --> 00:04:51.270
in the Attic section Engineers have


00:04:51.280 --> 00:04:53.230
added additional Vents and implemented a


00:04:53.240 --> 00:04:55.670
new Purge system that uses gaseous


00:04:55.680 --> 00:04:58.230
nitrogen future iterations of Starship


00:04:58.240 --> 00:05:00.830
will incorporate the new Raptor 3 engine


00:05:00.840 --> 00:05:02.590
which reduces the attic volume and


00:05:02.600 --> 00:05:04.310
eliminates many of the joints that could


00:05:04.320 --> 00:05:07.070
potentially leak the investigation was


00:05:07.080 --> 00:05:08.670
conducted under the oversight of the


00:05:08.680 --> 00:05:10.909
Federal Aviation Administration with


00:05:10.919 --> 00:05:13.110
participation from NASA the national


00:05:13.120 --> 00:05:15.390
Transportation safety board and the US


00:05:15.400 --> 00:05:18.590
space force SpaceX is now working


00:05:18.600 --> 00:05:20.350
closely with Regulators to obtain


00:05:20.360 --> 00:05:21.909
necessary approvals for their next


00:05:21.919 --> 00:05:24.110
launch attempt which could come as soon


00:05:24.120 --> 00:05:27.110
as this week pending regulatory


00:05:27.120 --> 00:05:28.950
clearance while on the subject of


00:05:28.960 --> 00:05:30.150

several NASA payloads aimed at exploring


00:05:55.720 --> 00:05:58.430
and analyzing the moon's subsurface this


00:05:58.440 --> 00:06:00.430
cuttingedge Mission will demonstrate new


00:06:00.440 --> 00:06:02.749
technologies crucial for future Artemis


00:06:02.759 --> 00:06:05.270
missions and lunar exploration also


00:06:05.280 --> 00:06:07.029
heading to deep space this week is


00:06:07.039 --> 00:06:09.909
NASA's spherex Observatory this


00:06:09.919 --> 00:06:11.950
Innovative telescope will map hundreds


00:06:11.960 --> 00:06:13.830
of millions of galaxies to study the


00:06:13.840 --> 00:06:16.230
origins of our universe and search for


00:06:16.240 --> 00:06:18.790
the fundamental building blocks of life


00:06:18.800 --> 00:06:21.550
using near infrared technology it will


00:06:21.560 --> 00:06:23.990
observe the sky in over 100 different


00:06:24.000 --> 00:06:26.589
color bands giving us unprecedented


00:06:26.599 --> 00:06:29.790
views of our Cosmic neighborhood blue or


00:06:29.800 --> 00:06:31.629
is set to resume their crude missions


00:06:31.639 --> 00:06:34.110

with multiple starlink launches


00:06:40.840 --> 00:06:42.510
scheduled to expand their Global


00:06:42.520 --> 00:06:43.670
Internet


00:06:43.680 --> 00:06:45.350
constellation perhaps the most


00:06:45.360 --> 00:06:47.029
anticipated launch of the week could be


00:06:47.039 --> 00:06:49.790
starship's e8th test flight tentatively


00:06:49.800 --> 00:06:52.309
scheduled for Friday following the

March rocket this impressive lineup of


00:07:19.080 --> 00:07:21.469
missions showcases just how busy and


00:07:21.479 --> 00:07:23.830
dynamic the space industry has become


00:07:23.840 --> 00:07:25.550
with both government agencies and


00:07:25.560 --> 00:07:27.710
private companies pushing the boundaries


00:07:27.720 --> 00:07:29.510
of space exploration and commerci


00:07:29.520 --> 00:07:31.350
commercial space


00:07:31.360 --> 00:07:33.430
operations let's turn our attention now


00:07:33.440 --> 00:07:35.629
to our beautiful star the sun put on


00:07:35.639 --> 00:07:37.670
quite a spectacular show this weekend


00:07:37.680 --> 00:07:40.589
unleashing a powerful X2 zero solar


00:07:40.599 --> 00:07:42.749
flare from a sunspot rotating out of our


00:07:42.759 --> 00:07:45.029
view the event peaked on Sunday


00:07:45.039 --> 00:07:47.869
afternoon at 2:27 p.m. eastern time


00:07:47.879 --> 00:07:49.749
triggering widespread radio blackouts


00:07:49.759 --> 00:07:52.149
across parts of the Pacific Ocean this


00:07:52.159 --> 00:07:54.029
wasn't just any ordinary solar flare it


00:07:54.039 --> 00:07:56.430
was an x-class event the most powerful


00:07:56.440 --> 00:07:58.950
category on our classification scale to


00:07:58.960 --> 00:08:01.270
put this perspective each increase in


00:08:01.280 --> 00:08:03.670
class represents a tenfold increase in


00:08:03.680 --> 00:08:06.990
energy making x-class flares truly


00:08:07.000 --> 00:08:10.149
remarkable events the 2.0 rating


00:08:10.159 --> 00:08:12.790
indicates this was a particularly potent


00:08:12.800 --> 00:08:15.510
example the intense burst of ultraviolet


00:08:15.520 --> 00:08:17.710
radiation from the flare caused


00:08:17.720 --> 00:08:19.710
significant disruption to high frequency


00:08:19.720 --> 00:08:21.629
radio communications throughout the


00:08:21.639 --> 00:08:24.350
sunlet regions of the Pacific during


00:08:24.360 --> 00:08:26.430
these blackout events radio operators


00:08:26.440 --> 00:08:28.070
experience either a complete loss of


00:08:28.080 --> 00:08:29.950
signal or severe degradation of their


00:08:29.960 --> 00:08:32.230
high frequency Communications the


00:08:32.240 --> 00:08:33.949
National Oceanic and Atmospheric


00:08:33.959 --> 00:08:35.790
Administration space weather prediction


00:08:35.800 --> 00:08:38.469
center classified this as an R3 or


00:08:38.479 --> 00:08:40.269
strong radio blackout event on their


00:08:40.279 --> 00:08:42.389
space weather scale while this falls


00:08:42.399 --> 00:08:44.269
short of the most severe categories of


00:08:44.279 --> 00:08:47.630
R4 severe or R5 extreme it still


00:08:47.640 --> 00:08:49.670
represents a significant space weather


00:08:49.680 --> 00:08:52.430
event fortunately the flare occurred


00:08:52.440 --> 00:08:54.350
just as its source Sunspot was rotating


00:08:54.360 --> 00:08:57.030
away from Earth this positioning meant


00:08:57.040 --> 00:08:58.509
that while we experienced radio


00:08:58.519 --> 00:09:00.870
disruptions we were spared from any


00:09:00.880 --> 00:09:03.710
potential coronal mass ejection impacts


00:09:03.720 --> 00:09:06.030
these massive eruptions of solar plasma


00:09:06.040 --> 00:09:08.190
can cause even more dramatic effects


00:09:08.200 --> 00:09:11.069
when they strike Earth's magnetic field


00:09:11.079 --> 00:09:13.069
space weather forecasters continue to


00:09:13.079 --> 00:09:15.630
monitor our star closely noting that


00:09:15.640 --> 00:09:17.150
there remains a slight chance of


00:09:17.160 --> 00:09:19.069
additional powerful flares through the


00:09:19.079 --> 00:09:21.509
middle of the week these events serve as


00:09:21.519 --> 00:09:23.590
Vivid reminders of the sun's incredible


00:09:23.600 --> 00:09:26.110
power and its ongoing influence on our


00:09:26.120 --> 00:09:28.350
technological systems here on


00:09:28.360 --> 00:09:30.870
Earth two fascinating studies are


00:09:30.880 --> 00:09:32.670
reshaping our understanding of some of


00:09:32.680 --> 00:09:34.550
the universe's most fundamental


00:09:34.560 --> 00:09:37.030
Mysteries theoretical physicists have


00:09:37.040 --> 00:09:39.190
discovered that gravitational waves


00:09:39.200 --> 00:09:40.990
those ripples in SpaceTime first


00:09:41.000 --> 00:09:43.389
predicted by Einstein might actually


00:09:43.399 --> 00:09:45.470
possess Quantum properties potentially


00:09:45.480 --> 00:09:47.030
Bridging the Gap between general


00:09:47.040 --> 00:09:49.670
relativity and quantum mechanics when


00:09:49.680 --> 00:09:52.069
massive objects like black holes Collide


00:09:52.079 --> 00:09:53.910
they create gravitational waves that


00:09:53.920 --> 00:09:56.030
stretch and squeeze Space by incredibly


00:09:56.040 --> 00:09:58.710
tiny amounts thousands of times smaller


00:09:58.720 --> 00:09:59.870
than an atom


00:09:59.880 --> 00:10:01.750
while current detectors like ligo can


00:10:01.760 --> 00:10:04.269
spot these classical waves researchers


00:10:04.279 --> 00:10:06.550
now believe that at the quantum level


00:10:06.560 --> 00:10:08.030
these waves might behave very


00:10:08.040 --> 00:10:10.990
differently using sophisticated models


00:10:11.000 --> 00:10:12.389
scientists found that Quantum


00:10:12.399 --> 00:10:14.670
gravitational waves could cause detector


00:10:14.680 --> 00:10:16.750
mirrors to become entangled meaning


00:10:16.760 --> 00:10:18.550
their movements become mysteriously


00:10:18.560 --> 00:10:21.230
linked in ways that classical physics


00:10:21.240 --> 00:10:23.990
simply cannot explain it's similar to


00:10:24.000 --> 00:10:26.389
two Windchimes swaying in perfect sync


00:10:26.399 --> 00:10:28.110
despite having no visible connection


00:10:28.120 --> 00:10:30.790
between them this discovery could


00:10:30.800 --> 00:10:32.829
revolutionize our understanding of the


00:10:32.839 --> 00:10:35.590
early Universe particularly around the


00:10:35.600 --> 00:10:37.910
time of the big bang when Quantum


00:10:37.920 --> 00:10:40.629
effects would have been most prominent


00:10:40.639 --> 00:10:42.710
it might also finally help reconcile


00:10:42.720 --> 00:10:44.430
Einstein's theory of gravity with


00:10:44.440 --> 00:10:46.829
quantum mechanics a challenge that has


00:10:46.839 --> 00:10:49.670
puzzled physicists for decades in a


00:10:49.680 --> 00:10:51.550
related breakthrough researchers have


00:10:51.560 --> 00:10:53.710
developed a new mathematical model


00:10:53.720 --> 00:10:56.030
showing how black holes might form


00:10:56.040 --> 00:10:57.590
without developing the mysterious


00:10:57.600 --> 00:11:00.590
singularities where physics breaks down


00:11:00.600 --> 00:11:02.750
instead of requiring exotic forms of


00:11:02.760 --> 00:11:04.790
matter they demonstrated that Pure


00:11:04.800 --> 00:11:06.269
Gravity alone could prevent these


00:11:06.279 --> 00:11:08.949
infinitely dense points from forming


00:11:08.959 --> 00:11:11.110
this elegant solution relies solely on


00:11:11.120 --> 00:11:13.470
modifications to Einstein's equations


00:11:13.480 --> 00:11:15.150
that naturally arise from quantum


00:11:15.160 --> 00:11:17.550
gravity while the current model Works in


00:11:17.560 --> 00:11:19.590
higher Dimensions the researchers


00:11:19.600 --> 00:11:21.430
believe the same principles should apply


00:11:21.440 --> 00:11:23.790
to our four-dimensional SpaceTime these


00:11:23.800 --> 00:11:25.230
findings don't just Advance our


00:11:25.240 --> 00:11:27.190
theoretical understanding they could


00:11:27.200 --> 00:11:28.949
have practical applications in helping


00:11:28.959 --> 00:11:30.949
us better understand the fate of matter


00:11:30.959 --> 00:11:33.430
falling into black holes and potentially


00:11:33.440 --> 00:11:35.629
even lead to observable signatures that


00:11:35.639 --> 00:11:38.230
future telescopes might detect it's a


00:11:38.240 --> 00:11:40.550
remarkable example of how exploring the


00:11:40.560 --> 00:11:43.190
quantum nature of gravity continues to


00:11:43.200 --> 00:11:45.710
unveil new secrets about our universe's


00:11:45.720 --> 00:11:48.269
most enigmatic


00:11:48.279 --> 00:11:50.389
phenomena well that brings us to the end
