Moon’s Hidden Geology, Venus’ DaVinci Mission, and Titan’s Atmospheric Secrets: S28E16
SpaceTime Series 28 Episode 16
The Astronomy, Space and Science News Podcast
New Discoveries on the Moon , Venus Exploration, and Titan's Atmosphere
In this episode of SpaceTime, we delve into a groundbreaking study revealing that the Moon may not be as geologically inactive as previously believed. Observations of small ridges on the lunar far side suggest recent tectonic activity, indicating that the Moon's geological history is more dynamic than once thought. Researchers found that these features, formed within the last 200 million years, could have significant implications for future lunar missions.
NASA's Davinci Mission to Venus
We also discuss NASA's upcoming Davinci mission, set to explore the mysteries of Venus. This innovative mission will deploy a descent probe into the planet's thick atmosphere, capturing high-resolution images and analyzing its unique geological features, including the ancient Tesserae that may provide insights into Venus's past.
Understanding Titan's Atmosphere
Additionally, we explore new research on Saturn's moon Titan, which maintains its dense nitrogen-rich atmosphere through chemical reactions occurring deep beneath its surface. The findings suggest that Titan's atmosphere, which features liquid methane rain and a complex organic chemistry, is replenished by internal processes that have puzzled scientists since its discovery.

As geologically Dead As previously
00:00:11.160 --> 00:00:13.310
thought a new mission to unlock the
00:00:13.320 --> 00:00:16.070
secrets of the planet Venus and how the
00:00:16.080 --> 00:00:19.470
saty moon Titan maintains its atmosphere
00:00:19.480 --> 00:00:22.710
all that and more coming up on
00:00:22.720 --> 00:00:25.870

00:00:35.570 --> 00:00:42.830
[Music]
00:00:42.840 --> 00:00:44.470
a new study has discovered that the
00:00:44.480 --> 00:00:46.549
Earth's Moon may not be as geologically
00:00:46.559 --> 00:00:49.069
dead as previously thought the findings
00:00:49.079 --> 00:00:50.709
are reported in the planetary science
00:00:50.719 --> 00:00:52.670
journal are based on observations of
00:00:52.680 --> 00:00:55.349
small ridges on the lunar Far Side
00:00:55.359 --> 00:00:56.670
scientists have studied the moon's
00:00:56.680 --> 00:00:58.750
surface for decades in order to help
00:00:58.760 --> 00:01:00.270
piece together its comp Le Lex
00:01:00.280 --> 00:01:02.869
geological and evolutionary history now
00:01:02.879 --> 00:01:04.950
evidence from Luna Maria there the dark
00:01:04.960 --> 00:01:06.550
flat areas of the Moon filled with
00:01:06.560 --> 00:01:08.510
solidified lava suggest that the moon
00:01:08.520 --> 00:01:09.990
must have experienced significant
00:01:10.000 --> 00:01:12.429
compression in its distant past
00:01:12.439 --> 00:01:14.590
researchers suspect that large arcing
00:01:14.600 --> 00:01:16.390
ridges on the moon's near side were
00:01:16.400 --> 00:01:17.990
formed by contractions that occurred
00:01:18.000 --> 00:01:20.190
billions of years ago as the moon cooled
00:01:20.200 --> 00:01:22.670
down and shrank and they concluded that
00:01:22.680 --> 00:01:24.789
the moon's maras remained dormant ever
00:01:24.799 --> 00:01:27.550
since however a new study reveals that
00:01:27.560 --> 00:01:29.390
What Lies Beneath the lunar surface may
00:01:29.400 --> 00:01:32.109
be more Dynamic than previously thought
00:01:32.119 --> 00:01:34.069
the authors discovered that small ridges
00:01:34.079 --> 00:01:35.950
located on the moon's Far Side are
00:01:35.960 --> 00:01:37.630
notably younger than those previously
00:01:37.640 --> 00:01:39.990
studed ridges on the near side one of
00:01:40.000 --> 00:01:41.630
the studies's authors jacqulyn Clark
00:01:41.640 --> 00:01:43.310
from the University of Maryland says
00:01:43.320 --> 00:01:44.910
many scientists believe that most of the
00:01:44.920 --> 00:01:46.709
moon's geological movements probably
00:01:46.719 --> 00:01:48.789
happened 2 and a half to maybe 3 billion
00:01:48.799 --> 00:01:50.950
years ago but Clark and colleagues are
00:01:50.960 --> 00:01:52.670
seeing that these tectonic landforms
00:01:52.680 --> 00:01:54.389
have been recently active around the
00:01:54.399 --> 00:01:56.350
last billion years or so and may still
00:01:56.360 --> 00:01:58.789
be active today the authors say these
00:01:58.799 --> 00:02:00.709
small maray ridges seem to have formed
00:02:00.719 --> 00:02:02.789
within the last 200 million years or so
00:02:02.799 --> 00:02:04.469
which is relatively recent considering
00:02:04.479 --> 00:02:07.029
the moon's time scale using Advanced
00:02:07.039 --> 00:02:08.669
mapping and modeling techniques the
00:02:08.679 --> 00:02:11.229
authors found 268 previously unknown
00:02:11.239 --> 00:02:13.949
smaller ridges on the Luna Far Side The
00:02:13.959 --> 00:02:15.910
Ridges typically appeared in groups of
00:02:15.920 --> 00:02:18.430
10 to 40 in volcanic regions that likely
00:02:18.440 --> 00:02:21.710
formed between 3.2 to 3.6 billion years
00:02:21.720 --> 00:02:23.949
ago in narrow areas where there may be
00:02:23.959 --> 00:02:25.790
underlying weaknesses in the moon's
00:02:25.800 --> 00:02:28.470
crust now to estimate the age of these
00:02:28.480 --> 00:02:30.190
small ridges the authors used a
00:02:30.200 --> 00:02:31.990
technique called crater counting and
00:02:32.000 --> 00:02:33.589
they found The Ridges were notably
00:02:33.599 --> 00:02:35.430
younger than other features in their
00:02:35.440 --> 00:02:37.430
surroundings crater counting is pretty
00:02:37.440 --> 00:02:39.190
simple essentially the more craters a
00:02:39.200 --> 00:02:41.149
surface has the older that surface is
00:02:41.159 --> 00:02:43.790
likely to be that's because the surfaces
00:02:43.800 --> 00:02:46.630
had more time to accumulate more craters
00:02:46.640 --> 00:02:48.070
after cutting the craters around these
00:02:48.080 --> 00:02:49.949
small ridges and seeing that some of the
00:02:49.959 --> 00:02:51.630
ridges actually cut through existing
00:02:51.640 --> 00:02:53.670
impact craters the authors believe that
00:02:53.680 --> 00:02:55.630
these land forms were tectonically
00:02:55.640 --> 00:02:58.949
active in the last 160 million years
00:02:58.959 --> 00:03:00.990
interestingly Mark noted that The Far
00:03:01.000 --> 00:03:02.910
Side ridges were similar in structure to
00:03:02.920 --> 00:03:04.750
the ones on the near side and that
00:03:04.760 --> 00:03:06.630
suggests that both were created by the
00:03:06.640 --> 00:03:08.830
same forces likely a combination of the
00:03:08.840 --> 00:03:10.789
moon's gradual shrinking and shifts in
00:03:10.799 --> 00:03:13.229
lunar orbit the Apollo missions of the
00:03:13.239 --> 00:03:15.589
late 60s and early' 70s detected a
00:03:15.599 --> 00:03:18.430
series of small shallow moonquakes and
00:03:18.440 --> 00:03:20.190
the new finding suggest that these small
00:03:20.200 --> 00:03:22.270
ridges might be related to similar
00:03:22.280 --> 00:03:24.789
seismic activity learning more about the
00:03:24.799 --> 00:03:26.430
evolution of the lunar surface could
00:03:26.440 --> 00:03:28.030
have important implications for the
00:03:28.040 --> 00:03:30.390
logistics of future Moon missions
00:03:30.400 --> 00:03:32.030
Clark hopes that future missions to the
00:03:32.040 --> 00:03:33.750
moon will include tools like ground
00:03:33.760 --> 00:03:35.710
penetrating radar so researchers can
00:03:35.720 --> 00:03:37.509
better understand the structures beneath
00:03:37.519 --> 00:03:40.070
the lunar surface and knowing where the
00:03:40.080 --> 00:03:42.309
Moon is still geologically Dynamic has
00:03:42.319 --> 00:03:44.350
very real implications for where NASA
00:03:44.360 --> 00:03:46.070
plans to put its astronauts equipment
00:03:46.080 --> 00:03:47.910
and infrastructure when it finally
00:03:47.920 --> 00:03:51.070
returns to stay on the lunar surface
00:03:51.080 --> 00:03:54.110
this is spacetime still to come a new
00:03:54.120 --> 00:03:55.670
mission to unlock the secrets of the
00:03:55.680 --> 00:03:58.350
planet Venus and how the saturnian moon
00:03:58.360 --> 00:04:01.550
Titan maintains its thick atmosphere all
00:04:01.560 --> 00:04:11.110
that and more still to come on
00:04:11.120 --> 00:04:18.870
[Music]
00:04:18.880 --> 00:04:21.110
SpaceTime there's been a lot of talk in
00:04:21.120 --> 00:04:22.990
the scientific media including here on
00:04:23.000 --> 00:04:25.270
SpaceTime about NASA's new mission to
00:04:25.280 --> 00:04:27.950
study the planet Venus it's called Da
00:04:27.960 --> 00:04:30.310
Vinci that stands for deep atmosphere
00:04:30.320 --> 00:04:32.270
Venus investigation of noble gases
00:04:32.280 --> 00:04:33.950
chemistry and imaging Mission which is
00:04:33.960 --> 00:04:36.990
slated to launch in the early 2030s the
00:04:37.000 --> 00:04:39.390
Vinci will explore Venus with both an
00:04:39.400 --> 00:04:42.189
orbital spacecraft and a Ascent module
00:04:42.199 --> 00:04:44.350
NASA says Da Vinci embodies the spirit
00:04:44.360 --> 00:04:46.390
of innovation and exploration that its
00:04:46.400 --> 00:04:49.310
namesake theed dichi was famous for
00:04:49.320 --> 00:04:51.390
it'll be the first probe of the 21st
00:04:51.400 --> 00:04:53.790
century to Brave Venus's atmosphere as
00:04:53.800 --> 00:04:55.550
it descends from above the planet's
00:04:55.560 --> 00:04:57.790
Cloud tops down to its heat soaked
00:04:57.800 --> 00:05:00.830
surface to other missions NASA's Veritas
00:05:00.840 --> 00:05:02.710
and the European space agency's Envision
00:05:02.720 --> 00:05:04.790
Mission will also explore Venus in the
00:05:04.800 --> 00:05:07.110
2030s but they'll both be doing that
00:05:07.120 --> 00:05:09.710
from orbit the D Vinci spacecraft will
00:05:09.720 --> 00:05:11.830
study Venus's clouds and Highlands
00:05:11.840 --> 00:05:14.629
during two flybys it'll also release a
00:05:14.639 --> 00:05:17.230
spherical meter wide probe that'll
00:05:17.240 --> 00:05:18.629
plunge through the planet's thick
00:05:18.639 --> 00:05:20.790
atmosphere in corrosive clouds taking
00:05:20.800 --> 00:05:22.110
measurements and capturing high
00:05:22.120 --> 00:05:24.390
resolution images of the venian surface
00:05:24.400 --> 00:05:27.029
as it slowly descends the D Vinci
00:05:27.039 --> 00:05:28.710
Mission will be the first to closely
00:05:28.720 --> 00:05:31.150
explore Alpha iio a region known as a
00:05:31.160 --> 00:05:34.110
Tessa so far only found on Venus where
00:05:34.120 --> 00:05:35.870
they make up about 8% of the planet
00:05:35.880 --> 00:05:38.150
surface Tess are Highland regions
00:05:38.160 --> 00:05:40.110
similar in appearance to rugged mountain
00:05:40.120 --> 00:05:42.629
tabletops on Earth geologists believe
00:05:42.639 --> 00:05:45.070
they may be exposed cratons ancient
00:05:45.080 --> 00:05:46.790
structures that have extended up through
00:05:46.800 --> 00:05:49.469
the mantle and Crist previous missions
00:05:49.479 --> 00:05:51.230
discover these tessay features using
00:05:51.240 --> 00:05:53.390
radar instruments but of the many
00:05:53.400 --> 00:05:55.469
spacecraft that Dove through Venus's
00:05:55.479 --> 00:05:58.710
atmosphere between 1966 and 1985 none
00:05:58.720 --> 00:06:01.230
studied or photograph gra these Tess
00:06:01.240 --> 00:06:03.670
thought to be ancient continents Tess
00:06:03.680 --> 00:06:05.830
like alphar Rio may be among the oldest
00:06:05.840 --> 00:06:07.710
surfaces on the planet offering
00:06:07.720 --> 00:06:09.309
scientists access to rocks that are
00:06:09.319 --> 00:06:12.029
billions of years old by studying these
00:06:12.039 --> 00:06:13.790
rocks a Vinci scientists May learn
00:06:13.800 --> 00:06:15.670
whether Venus ever had continents and
00:06:15.680 --> 00:06:18.029
oceans and how water may have influenced
00:06:18.039 --> 00:06:20.350
the surface as well as being Earth's
00:06:20.360 --> 00:06:22.430
nearest planetary neighbor Venus is
00:06:22.440 --> 00:06:24.710
considered to be Earth's sister Planet
00:06:24.720 --> 00:06:26.670
they're both almost the same size with a
00:06:26.680 --> 00:06:28.550
similar mass and diameter both were
00:06:28.560 --> 00:06:30.070
formed under similar condition ions out
00:06:30.080 --> 00:06:31.830
of the same materials and in the same
00:06:31.840 --> 00:06:34.309
part of the solar system in fact Venice
00:06:34.319 --> 00:06:36.189
once excited speculation that it could
00:06:36.199 --> 00:06:39.309
host the first human colony in space see
00:06:39.319 --> 00:06:41.430
back in the 50s and 60s scientists
00:06:41.440 --> 00:06:43.189
thought the dense cloud cover meant lots
00:06:43.199 --> 00:06:45.550
of rain after all it's closer to the Sun
00:06:45.560 --> 00:06:46.909
than the Earth is so temperatures would
00:06:46.919 --> 00:06:48.790
be hotter and more humid that would mean
00:06:48.800 --> 00:06:50.870
more water evaporation and more
00:06:50.880 --> 00:06:53.390
rainclouds so scientists of the day en
00:06:53.400 --> 00:06:55.309
Vis that under its thick cloud cover
00:06:55.319 --> 00:06:57.309
Earth's sister planet was covered in a
00:06:57.319 --> 00:07:00.110
lush green tropical rainforest Amazon
00:07:00.120 --> 00:07:02.869
jungle on steroids and more rain
00:07:02.879 --> 00:07:04.950
probably meant a higher oxygen content
00:07:04.960 --> 00:07:07.189
too and so some scientists even began
00:07:07.199 --> 00:07:08.550
speculating that the tropical
00:07:08.560 --> 00:07:10.869
rainforests of Venus somehow meant lots
00:07:10.879 --> 00:07:11.629
of
00:07:11.639 --> 00:07:14.029
dinosaurs of course we now know that if
00:07:14.039 --> 00:07:16.350
Venus is Earth sister Planet then it's a
00:07:16.360 --> 00:07:18.830
twisted sister with a massive runaway
00:07:18.840 --> 00:07:21.150
greenhouse effect in fact Soviet and
00:07:21.160 --> 00:07:23.029
American probes have revealed Venus to
00:07:23.039 --> 00:07:24.670
be the nearest thing to hell in our
00:07:24.680 --> 00:07:27.469
solar system its surface is scorchingly
00:07:27.479 --> 00:07:30.909
hot with average temperatures of 4 62° C
00:07:30.919 --> 00:07:33.189
that's hot enough to melt lead and those
00:07:33.199 --> 00:07:35.110
thick opaque Planet shrouding clouds
00:07:35.120 --> 00:07:37.189
well they do cause rain but the rain
00:07:37.199 --> 00:07:39.270
isn't water instead it's droplets of
00:07:39.280 --> 00:07:41.749
metal eating sulfuric acid now
00:07:41.759 --> 00:07:43.150
scientists have seen what looks like
00:07:43.160 --> 00:07:44.990
snow caps on some of venice's taller
00:07:45.000 --> 00:07:47.189
mountain ranges but the snow isn't
00:07:47.199 --> 00:07:49.589
frozen water it's actually metallic
00:07:49.599 --> 00:07:51.950
Venus's clouds are so heavy they crush
00:07:51.960 --> 00:07:53.869
the planet's Rich carbon dioxide based
00:07:53.879 --> 00:07:55.710
atmosphere acting like a sort of lid on
00:07:55.720 --> 00:07:57.390
a pressure cooker and giving the planet
00:07:57.400 --> 00:08:00.110
a surface pressure 92 times greater than
00:08:00.120 --> 00:08:01.869
the average sea level surface pressure
00:08:01.879 --> 00:08:04.309
on Earth the surface is dominated by
00:08:04.319 --> 00:08:07.469
over, 1600 volcanic structures more than
00:08:07.479 --> 00:08:10.070
any other planet in the solar system its
00:08:10.080 --> 00:08:12.670
surface is 90% bass Sal and consist of a
00:08:12.680 --> 00:08:14.990
mosaic of volcanic lava planes showing
00:08:15.000 --> 00:08:17.029
evidence of regular periodic resurfacing
00:08:17.039 --> 00:08:19.710
by floods of magma now this indicates
00:08:19.720 --> 00:08:21.950
that volcanism played and maybe still is
00:08:21.960 --> 00:08:23.950
playing a major role in shaping the
00:08:23.960 --> 00:08:26.749
planet's surface even Venus's orbital
00:08:26.759 --> 00:08:28.909
characteristics are strange it circles
00:08:28.919 --> 00:08:32.149
the Sun every 224.000 Earth days but it
00:08:32.159 --> 00:08:34.389
rotates in retrograde compared to most
00:08:34.399 --> 00:08:36.149
other planets in the solar system in
00:08:36.159 --> 00:08:38.029
other words the sun rises in the west
00:08:38.039 --> 00:08:40.389
and sets in the East and the rotation
00:08:40.399 --> 00:08:43.350
rate is incredibly slow a day on Venus
00:08:43.360 --> 00:08:46.150
lasts 243 Earth days in other words a
00:08:46.160 --> 00:08:48.509
venesian day actually lasts longer than
00:08:48.519 --> 00:08:53.030
its year this report from NASA TV Venus
00:08:53.040 --> 00:08:55.949
a planet with an ocean of air unexplored
00:08:55.959 --> 00:08:58.030
in the ways we look at the worlds around
00:08:58.040 --> 00:09:00.350
us and Beyond we're going back to that
00:09:00.360 --> 00:09:02.750
ocean of air at our sister world with a
00:09:02.760 --> 00:09:05.509
mission inspired by Leonardo called Da
00:09:05.519 --> 00:09:08.470
Vinci to explore from the cloud deck to
00:09:08.480 --> 00:09:11.269
the surface over a region of mountains
00:09:11.279 --> 00:09:13.870
that could hold Clues to how the early
00:09:13.880 --> 00:09:15.630
history of Worlds like Venus and Earth
00:09:15.640 --> 00:09:17.750
worked but by reading the chemical
00:09:17.760 --> 00:09:21.150
fossils in the atmosphere the Dynamics
00:09:21.160 --> 00:09:23.750
and the other forensic Clues to how an
00:09:23.760 --> 00:09:27.030
entire world with this ocean of air
00:09:27.040 --> 00:09:29.750
Works will learn about not only our own
00:09:29.760 --> 00:09:31.710
solar system and the history of Venus
00:09:31.720 --> 00:09:33.310
and whether it was habitable at one
00:09:33.320 --> 00:09:36.069
point but also push that record forward
00:09:36.079 --> 00:09:39.030
to explore exoplanets that are like
00:09:39.040 --> 00:09:41.350
Venus which we suspect are abundant
00:09:41.360 --> 00:09:43.389
around favorable
00:09:43.399 --> 00:09:46.310
Stars Da Vinci will be the Gateway that
00:09:46.320 --> 00:09:49.310
opens that door so we can explore better
00:09:49.320 --> 00:09:52.230
here and apply that forward Beyond as we
00:09:52.240 --> 00:09:55.389
go into eras of gigantic observatories
00:09:55.399 --> 00:09:57.110
Beyond James web like the habitable

world's Observatory
00:10:00.079 --> 00:10:03.030
Venus is waiting and we can't wait to
00:10:03.040 --> 00:10:06.430
get back there this is spacetime still
00:10:06.440 --> 00:10:08.710
to come a new mission to study how the
00:10:08.720 --> 00:10:10.630
saturnian moon Titan maintains its
00:10:10.640 --> 00:10:12.389
atmosphere and later in the science
00:10:12.399 --> 00:10:15.230
report new research shows dant volcanoes
00:10:15.240 --> 00:10:17.949
can still retain massive magma Chambers
00:10:17.959 --> 00:10:19.870
all that and more still to come on
00:10:19.880 --> 00:10:36.269
SpaceTime
00:10:36.279 --> 00:10:38.389
a new study suggest that the saturnian
00:10:38.399 --> 00:10:40.949
moon Titan maintains its unique nitrogen
00:10:40.959 --> 00:10:42.710
Rich atmosphere through High Press
00:10:42.720 --> 00:10:44.430
chemical reactions deep below the
00:10:44.440 --> 00:10:46.629
surface the findings reported in the
00:10:46.639 --> 00:10:49.829
journal geoa at cosmoem actor based on
00:10:49.839 --> 00:10:51.710
laboratory experiments which produce
00:10:51.720 --> 00:10:53.269
gases similar to those found on the
00:10:53.279 --> 00:10:55.829
saturnian moon Titan is the second
00:10:55.839 --> 00:10:57.670
largest moon in our solar system after
00:10:57.680 --> 00:10:59.670
gany and it's the only one one that has
00:10:59.680 --> 00:11:02.030
a significant atmosphere it's also the
00:11:02.040 --> 00:11:03.710
only World in our solar system other
00:11:03.720 --> 00:11:05.509
than Earth where clouds rain down
00:11:05.519 --> 00:11:07.310
liquids onto the surface on a regular
00:11:07.320 --> 00:11:09.990
basis forming streams and rivers which
00:11:10.000 --> 00:11:12.910
eventually flow into lakes and seas but
00:11:12.920 --> 00:11:14.949
instead of Earth's liquid water on
00:11:14.959 --> 00:11:16.990
tighten the weather's so cold the rain
00:11:17.000 --> 00:11:19.829
is liquid methane and ethane now there
00:11:19.839 --> 00:11:21.829
is water untightened but it's frozen
00:11:21.839 --> 00:11:23.910
solid so hard that it forms much of the
00:11:23.920 --> 00:11:26.389
moon's Bedrock the study's lead author
00:11:26.399 --> 00:11:28.269
Kelly Miller from the southwest Research
00:11:28.279 --> 00:11:30.829
Institute in San ant Texas says while
00:11:30.839 --> 00:11:33.350
just 40% the diameter of the earth Titan
00:11:33.360 --> 00:11:35.230
is an atmosphere 1 and a half times as
00:11:35.240 --> 00:11:36.990
dense as the Earth even with its lower
00:11:37.000 --> 00:11:39.190
gravity Miller says walking on the
00:11:39.200 --> 00:11:40.949
surface of Titan would actually feel a
00:11:40.959 --> 00:11:44.030
lot like scuba diving the origin age and
00:11:44.040 --> 00:11:46.030
evolution of Titan's atmosphere which is
00:11:46.040 --> 00:11:49.269
roughly 95% nitrogen and 5% methane has
00:11:49.279 --> 00:11:50.910
puzzled scientist ever since it was
00:11:50.920 --> 00:11:52.430
first discovered in
00:11:52.440 --> 00:11:55.110
1944 Miller says the presence of methane
00:11:55.120 --> 00:11:57.069
is critical to the existence of Titan's
00:11:57.079 --> 00:11:59.509
atmosphere see methane is removed moved
00:11:59.519 --> 00:12:01.430
by reactions caused by sunlight and it
00:12:01.440 --> 00:12:02.990
would disappear in about 30 million
00:12:03.000 --> 00:12:04.710
years after which what's left of the
00:12:04.720 --> 00:12:06.350
atmosphere would simply freeze onto the
00:12:06.360 --> 00:12:08.790
surface now because of methane's short
00:12:08.800 --> 00:12:10.710
geological lifespan scientists think
00:12:10.720 --> 00:12:12.590
some sort of internal process must be
00:12:12.600 --> 00:12:15.030
replenishing the methane Miller who was
00:12:15.040 --> 00:12:17.150
also the lead author of a 2019 paper
00:12:17.160 --> 00:12:18.750
published in the astrophysical journal
00:12:18.760 --> 00:12:20.550
has proposed a theoretical model to show
00:12:20.560 --> 00:12:22.550
how the moon's atmosphere has developed
00:12:22.560 --> 00:12:25.150
and is being replenished over the years
00:12:25.160 --> 00:12:27.230
the paper hypothesizes that large
00:12:27.240 --> 00:12:28.829
amounts of Highly complex organic
00:12:28.839 --> 00:12:30.509
material materals are heated up in
00:12:30.519 --> 00:12:33.150
Titan's Rocky interior and that releases
00:12:33.160 --> 00:12:35.189
nitrogen as well as carbon gases like
00:12:35.199 --> 00:12:37.629
methane these gases then sep out onto
00:12:37.639 --> 00:12:39.550
the surface forming a thick atmosphere
00:12:39.560 --> 00:12:41.750
around the moon now this theory is
00:12:41.760 --> 00:12:43.829
corroborated by recent experiments that
00:12:43.839 --> 00:12:45.389
heated organic materials the
00:12:45.399 --> 00:12:48.710
temperatures of around 250 to 500° C at
00:12:48.720 --> 00:12:50.990
pressures of up to 10 kilobars in order
00:12:51.000 --> 00:12:53.189
to simulate the interior conditions of
00:12:53.199 --> 00:12:55.829
Titan and the experiments produce carbon
00:12:55.839 --> 00:12:57.949
gases like carbon dioxide and methane in
00:12:57.959 --> 00:13:00.310
sufficient quantities Supply Titan's
00:13:00.320 --> 00:13:02.509
atmospheric Reservoir the paper is
00:13:02.519 --> 00:13:04.750
largely based on NASA's Cassini hyan
00:13:04.760 --> 00:13:07.310
spacecraft which launched in 1977 and
00:13:07.320 --> 00:13:09.069
explored the saturnian system between
00:13:09.079 --> 00:13:12.269
2014 and 2017 during that mission
00:13:12.279 --> 00:13:14.470
Cassini deployed the hyan Lander which
00:13:14.480 --> 00:13:16.470
descended through the atmosphere landing
00:13:16.480 --> 00:13:19.790
on Titan's surface images show a surface
00:13:19.800 --> 00:13:22.629
which felt like wet sand NASA plans to
00:13:22.639 --> 00:13:24.230
launch another mission to the saturnian
00:13:24.240 --> 00:13:26.590
system in 2028 with a spacecraft
00:13:26.600 --> 00:13:29.310
helicopter drone named dragonfly the
00:13:29.320 --> 00:13:31.470
dragonfly quadcopter will be designed to
00:13:31.480 --> 00:13:33.670
explore Titan up close and investigate
00:13:33.680 --> 00:13:35.550
whether environments at Titan could have
00:13:35.560 --> 00:13:38.790
ever been condusive for life this report
00:13:38.800 --> 00:13:41.750
from Nessa TV our next New Frontiers
00:13:41.760 --> 00:13:45.069
Mission dragonfly will explore Saturn's
00:13:45.079 --> 00:13:47.949
largest moon Titan dragonfly will be the
00:13:47.959 --> 00:13:50.189
first drone Lander with the capability
00:13:50.199 --> 00:13:53.030
to fly over a 100 miles through Titan's
00:13:53.040 --> 00:13:55.790
thick atmosphere Titan is unlike any
00:13:55.800 --> 00:13:57.790
other place in our solar system and the
00:13:57.800 --> 00:14:00.350
most comparable to early Earth the
00:14:00.360 --> 00:14:02.030
instruments on board will help us
00:14:02.040 --> 00:14:04.550
investigate organic chemistry and search
00:14:04.560 --> 00:14:07.670
for chemical signatures of past or even
00:14:07.680 --> 00:14:08.910
present
00:14:08.920 --> 00:14:12.550
life so we have on tightened opportunity
00:14:12.560 --> 00:14:14.829
to observe the processes um that were
00:14:14.839 --> 00:14:16.870
present on early Earth when life began
00:14:16.880 --> 00:14:19.269
to form and possibly even conditions
00:14:19.279 --> 00:14:22.189
that may be able to Harbor life today
00:14:22.199 --> 00:14:24.590
one of the things that is particularly
00:14:24.600 --> 00:14:26.509
exciting about this mission is that we
00:14:26.519 --> 00:14:29.509
can do the very detailed chemical measur
00:14:29.519 --> 00:14:31.389
but be able to put them in the context
00:14:31.399 --> 00:14:34.560
of Titan as a system this is
00:14:34.570 --> 00:14:49.389
[Music]
00:14:49.399 --> 00:14:51.509
spacetime and time that to take another
00:14:51.519 --> 00:14:52.790
brief look at some of the other stories
00:14:52.800 --> 00:14:54.629
making news and science this week with a
00:14:54.639 --> 00:14:57.550
science report a new study warns that
00:14:57.560 --> 00:14:59.030
temperature related deaths in Europe
00:14:59.040 --> 00:15:01.030
European cities could increase by up to
00:15:01.040 --> 00:15:04.069
50% resulting in some 2.3 million
00:15:04.079 --> 00:15:05.829
additional deaths by the end of the
00:15:05.839 --> 00:15:08.069
century the findings reported in the
00:15:08.079 --> 00:15:10.150
journal Nature medicine based on climate
00:15:10.160 --> 00:15:13.269
simulations using data on 854 urban
00:15:13.279 --> 00:15:16.509
areas across 30 European countries these
00:15:16.519 --> 00:15:18.430
were used to estimate deaths from very
00:15:18.440 --> 00:15:20.350
cold and very hot temperatures with
00:15:20.360 --> 00:15:21.910
increased deaths from extreme heat
00:15:21.920 --> 00:15:23.990
outpacing increased deaths from extreme
00:15:24.000 --> 00:15:26.590
cold the authors claim strong climate
00:15:26.600 --> 00:15:28.550
change mitigation measures could reduce
00:15:28.560 --> 00:15:30.110
the number of additional deaths to just
00:15:30.120 --> 00:15:31.949
over a quarter of a million people by
00:15:31.959 --> 00:15:33.910
the year
00:15:33.920 --> 00:15:36.150
2100 scientists have discovered that
00:15:36.160 --> 00:15:37.910
contrary to popular belief dormant
00:15:37.920 --> 00:15:39.870
volcanoes sleeping for hundreds of
00:15:39.880 --> 00:15:42.069
thousands of years can still retain
00:15:42.079 --> 00:15:44.670
massive magma Chambers the findings
00:15:44.680 --> 00:15:45.949
reported in the journal Nature

geoscience found large magma Chambers
00:15:48.440 --> 00:15:50.509
lurking beneath six volcanoes thought to
00:15:50.519 --> 00:15:52.350
be dormant in the Pacific Northwest
00:15:52.360 --> 00:15:54.910
Cascades range the new discovery
00:15:54.920 --> 00:15:57.110
challenges existing ideas of exactly
00:15:57.120 --> 00:15:59.350
what separates an active volcano from a
00:15:59.360 --> 00:16:02.030
dormant one the authors use seismometers
00:16:02.040 --> 00:16:04.110
to identify persistent and large magma
00:16:04.120 --> 00:16:05.870
Chambers in all six of the dormant
00:16:05.880 --> 00:16:08.189
volcanoes they studied the results
00:16:08.199 --> 00:16:10.389
suggest that eruptions Do Not always
00:16:10.399 --> 00:16:13.470
completely drain a magma chamber instead
00:16:13.480 --> 00:16:15.430
it will release some of the excess
00:16:15.440 --> 00:16:17.230
volume and pressure and the magma
00:16:17.240 --> 00:16:19.550
chamber can then slowly be expanded and
00:16:19.560 --> 00:16:21.629
refilled over time as the crust
00:16:21.639 --> 00:16:23.309
gradually
00:16:23.319 --> 00:16:25.590
melts Chinese scientists have
00:16:25.600 --> 00:16:27.389
successfully used embryonic stem cell
00:16:27.399 --> 00:16:29.749
engineering to create a by paternal
00:16:29.759 --> 00:16:32.110
mouse that is a mouse with two dads
00:16:32.120 --> 00:16:33.629
which was able to survive until
00:16:33.639 --> 00:16:35.910
adulthood a report of the journal cell
00:16:35.920 --> 00:16:37.629
stem cell claims the authors had
00:16:37.639 --> 00:16:39.629
attempted to create bip paternal mice
00:16:39.639 --> 00:16:41.509
before but the embryos all stopped
00:16:41.519 --> 00:16:43.990
growing in this new study they focused
00:16:44.000 --> 00:16:46.069
on imprinting genes which regulate gene
00:16:46.079 --> 00:16:47.590
activity and were thought to be a
00:16:47.600 --> 00:16:49.670
fundamental barrier to creating a mouse
00:16:49.680 --> 00:16:52.150
with two parents of the same sex the
00:16:52.160 --> 00:16:55.110
authors modified 20 key imprinting genes
00:16:55.120 --> 00:16:56.910
finding that not only did this allow the
00:16:56.920 --> 00:16:59.030
creation of bip paternal animals that
00:16:59.040 --> 00:17:00.710
sometimes lived to adulthood but it also
00:17:00.720 --> 00:17:03.350
led to more stable stem cells however
00:17:03.360 --> 00:17:05.110
only around one in8 of the viable
00:17:05.120 --> 00:17:07.669
embryos developed until birth and not
00:17:07.679 --> 00:17:09.710
all the pups that were born lived to
00:17:09.720 --> 00:17:12.309
adulthood due to developmental defects
00:17:12.319 --> 00:17:14.549
also those that did live to adulthood
00:17:14.559 --> 00:17:16.029
had altered growth and shortened
00:17:16.039 --> 00:17:18.630
lifespans and were
00:17:18.640 --> 00:17:21.390
sterile Chinese company deep sick has
00:17:21.400 --> 00:17:23.549
developed a new AI chatbot which he
00:17:23.559 --> 00:17:25.390
claims Rivals chat
00:17:25.400 --> 00:17:27.909
GPT the new technology was reportedly
00:17:27.919 --> 00:17:29.789
developed using fuel and less Advanced
00:17:29.799 --> 00:17:32.470
chips than its American Rivals it's Now
00:17:32.480 --> 00:17:33.789
quickly become the world's most
00:17:33.799 --> 00:17:35.909
downloaded app causing technology stocks
00:17:35.919 --> 00:17:39.070
to crash globally however deep seik
00:17:39.080 --> 00:17:41.390
isn't really that good it's heavily
00:17:41.400 --> 00:17:42.990
censored by the Chinese communist
00:17:43.000 --> 00:17:45.190
government and refuses to discuss topics
00:17:45.200 --> 00:17:47.230
which are sensitive to Beijing including
00:17:47.240 --> 00:17:48.909
the weager people's enslavement in
00:17:48.919 --> 00:17:50.830
so-called re-education camps the
00:17:50.840 --> 00:17:52.590
slaughter of felong gong members for
00:17:52.600 --> 00:17:55.830
forc organ donations and the Bloody 1989
00:17:55.840 --> 00:17:58.470
tanaman Square massacre there are also
00:17:58.480 --> 00:18:00.510
major your security concerns with deep

video and audio inputs are collected
00:18:10.799 --> 00:18:12.789
automatically of course this isn't the
00:18:12.799 --> 00:18:14.590
first time there's been concerns about
00:18:14.600 --> 00:18:17.510
Chinese technology in 2018 the
00:18:17.520 --> 00:18:19.070
Australian government banned Chinese
00:18:19.080 --> 00:18:21.230
telecommunications giant Huawei from its
00:18:21.240 --> 00:18:23.549
National 5G Network citing National
00:18:23.559 --> 00:18:26.029
Security concerns it's also banned the
00:18:26.039 --> 00:18:27.990
use of the Tik Tok app on Department of
00:18:28.000 --> 00:18:29.909
Defense and government cell phones and
00:18:29.919 --> 00:18:33.230
computers see as a Chinese firm deep
00:18:33.240 --> 00:18:35.029
required to follow China's strict
00:18:35.039 --> 00:18:37.669
censorship laws and regulations ensuring
00:18:37.679 --> 00:18:39.909
the new AI conforms to beijing's
00:18:39.919 --> 00:18:42.830
communist values technology editor Alex
00:18:42.840 --> 00:18:45.270
saharov Roy from Tech advice. life has
00:18:45.280 --> 00:18:47.029
tested deep seek and here's what he
00:18:47.039 --> 00:18:49.990
found well deep seek is an AI chatbot in
00:18:50.000 --> 00:18:53.029
the style of chat gbt or co-pilot or
00:18:53.039 --> 00:18:55.590
grock and its breakthrough is that it
00:18:55.600 --> 00:18:58.870
seems to deliver very similar sorts of
00:18:58.880 --> 00:19:01.270
results to what you'd get with chat GPT
00:19:01.280 --> 00:19:03.070
in fact some of the benchmarks show that
00:19:03.080 --> 00:19:06.110
it's more accurate but the creators
00:19:06.120 --> 00:19:08.710
claim to have done this without the
00:19:08.720 --> 00:19:11.270
massive investment in h100
00:19:11.280 --> 00:19:14.350
top-of-the-line Nvidia chips nor the
00:19:14.360 --> 00:19:17.510
billions of dollars if not uh tens or
00:19:17.520 --> 00:19:18.909
even hundreds of billions of dollars of
00:19:18.919 --> 00:19:21.549
investment that has gone into creating
00:19:21.559 --> 00:19:24.190
this algorithm now an interesting thing
00:19:24.200 --> 00:19:26.230
is that when you download the app you
00:19:26.240 --> 00:19:28.710
have this option to tap deep research I
00:19:28.720 --> 00:19:30.870
I think it is R1 and what happens then
00:19:30.880 --> 00:19:34.110
is that you see the AI reasoning with
00:19:34.120 --> 00:19:36.350
itself sort of giving itself a
00:19:36.360 --> 00:19:38.230
instructions on how it's going to
00:19:38.240 --> 00:19:40.350
respond to your question even harking
00:19:40.360 --> 00:19:42.070
back to previous interactions that
00:19:42.080 --> 00:19:44.190
you've had and then it gives you the
00:19:44.200 --> 00:19:45.590
response so we haven't actually been
00:19:45.600 --> 00:19:48.950
able to see AI do that normally AI is a
00:19:48.960 --> 00:19:50.789
black box there is this concept of
00:19:50.799 --> 00:19:53.190
explainable AI which people want so they
00:19:53.200 --> 00:19:55.470
know what the AI is is thinking and why
00:19:55.480 --> 00:19:57.390
it's coming up with those responses and
00:19:57.400 --> 00:19:58.990
and again as I said this is something we
00:19:59.000 --> 00:20:01.190
haven't seen with the other models now
00:20:01.200 --> 00:20:03.390
the claim is that this was done for $6
00:20:03.400 --> 00:20:07.669
million us and the trick is that instead
00:20:07.679 --> 00:20:10.190
of having huge amounts of processors to
00:20:10.200 --> 00:20:12.149
generate and calculate each token this
00:20:12.159 --> 00:20:14.310
new model is able to somehow predict the
00:20:14.320 --> 00:20:16.310
tokens it would need but the criticisms
00:20:16.320 --> 00:20:19.070
are that he has been using chat gpt's
00:20:19.080 --> 00:20:21.310
own results and research to come up with
00:20:21.320 --> 00:20:23.270
its answers that it is getting a lot
00:20:23.280 --> 00:20:26.870
more funding from the Chinese government
00:20:26.880 --> 00:20:29.270
than is being led on and and it is
00:20:29.280 --> 00:20:31.909
actually using h800 chips these are
00:20:31.919 --> 00:20:34.510
Nvidia chips designed to be sold into
00:20:34.520 --> 00:20:36.470
the Chinese market but they have about
00:20:36.480 --> 00:20:39.029
half the chipto chip speed in terms of
00:20:39.039 --> 00:20:40.750
being able to talk to each other so this
00:20:40.760 --> 00:20:42.990
is meant to slow down the Chinese
00:20:43.000 --> 00:20:45.710
advancements there are concerns that the
00:20:45.720 --> 00:20:48.510
app will take your IP address and your
00:20:48.520 --> 00:20:50.710
logs and the the version of the
00:20:50.720 --> 00:20:52.390
operating system and the hardware that
00:20:52.400 --> 00:20:54.830
you have and it will also like Tik Tok
00:20:54.840 --> 00:20:58.110
capture your keystroke rhythms and
00:20:58.120 --> 00:21:00.110
pattern now this is not actually key
00:21:00.120 --> 00:21:01.909
logging where it's getting your exact
00:21:01.919 --> 00:21:03.669
keystrokes that you're typing but for
00:21:03.679 --> 00:21:06.149
security and sort of other nefarious you
00:21:06.159 --> 00:21:08.350
know sounding purposes it is capturing
00:21:08.360 --> 00:21:10.990
this information to verify that it's you
00:21:11.000 --> 00:21:12.630
and the concern is and people have
00:21:12.640 --> 00:21:13.990
claimed that it's capturing your
00:21:14.000 --> 00:21:16.230
passwords and able to take your photos
00:21:16.240 --> 00:21:18.230
and images but I don't see any evidence
00:21:18.240 --> 00:21:20.269
of that I mean other apps are capturing
00:21:20.279 --> 00:21:22.549
this keystroke information as well uh
00:21:22.559 --> 00:21:24.149
there were there was talks at Facebook
00:21:24.159 --> 00:21:25.909
even if you weren't hitting send on a
00:21:25.919 --> 00:21:27.510
post you were making within its app it
00:21:27.520 --> 00:21:29.230
were still capturing that information
00:21:29.240 --> 00:21:30.789
anyway which is worse than what is
00:21:30.799 --> 00:21:33.149
claimed with deep seek but it is true
00:21:33.159 --> 00:21:35.830
that if you insert or input information
00:21:35.840 --> 00:21:37.990
into deep seek for it to do its
00:21:38.000 --> 00:21:39.789
calculations and come up with an answer
00:21:39.799 --> 00:21:41.269
that is information you're giving to the
00:21:41.279 --> 00:21:43.510
system which you can put into a profile
00:21:43.520 --> 00:21:45.430
against your user name that you have to
00:21:45.440 --> 00:21:47.269
sign up with and it is stored on Chinese
00:21:47.279 --> 00:21:49.390
service so look I downloaded it I tried
00:21:49.400 --> 00:21:51.430
it I looked at it it works it's pretty
00:21:51.440 --> 00:21:53.510
cool I've since deleted it because I
00:21:53.520 --> 00:21:55.710
have chat gbt I have grock and I don't
00:21:55.720 --> 00:21:57.350
know whether to trust this particular
00:21:57.360 --> 00:21:59.029
app or not but it is the number one out
00:21:59.039 --> 00:22:00.870
in the US in Australia and other
00:22:00.880 --> 00:22:02.110
countries as well so a lot of people
00:22:02.120 --> 00:22:04.590
have looked at it and if it is true that
00:22:04.600 --> 00:22:06.750
the system can do a better job with
00:22:06.760 --> 00:22:08.549
resources than what the current models
00:22:08.559 --> 00:22:10.549
in the US are able to come up with well
00:22:10.559 --> 00:22:12.510
it's open source so that information can
00:22:12.520 --> 00:22:14.909
be easily consumed with inter chat gbt
00:22:14.919 --> 00:22:16.630
or grock or other systems and they can
00:22:16.640 --> 00:22:18.830
get an incredible boost as well and look
00:22:18.840 --> 00:22:20.830
the final story on whether this is some
00:22:20.840 --> 00:22:22.630
giant spy tool that's yet to be told but
00:22:22.640 --> 00:22:24.549
it's horses for hes you can play with it
00:22:24.559 --> 00:22:25.830
and find out for yourself but you'll get
00:22:25.840 --> 00:22:27.149
the same sort of results you'll get from
00:22:27.159 --> 00:22:29.070
