Asteroid 2024 YR4 Threat, Lunar Canyon Formation, and NASA Astronauts’ Early Homecoming: S28E24
SpaceTime Series 28 Episode 24
The Astronomy, Space and Science News Podcast
Asteroid Impact Odds, Lunar Grand Canyons, and NASA's Stranded Astronauts
In this episode of SpaceTime, we discuss the alarming increase in the odds of asteroid 2024 YR4 impacting Earth, now estimated at 3.1% for December 22, 2032. This asteroid, measuring between 40 to 90 meters, poses a significant threat, and we delve into the implications of planetary defense strategies that could be employed to mitigate this risk.
The Origins of the Moon's Grand Canyons
We also explore new research that suggests the Moon's massive canyons, Vallis Schrodinger and Valles Plank, were carved out by asteroid impacts in a mere 10 minutes. This groundbreaking study provides insights into the Moon's geological history and will have important implications for future lunar missions, particularly the upcoming Artemis program.
NASA's Stranded Astronauts
Additionally, we cover the latest developments regarding NASA astronauts Sunita Williams and Butch Wiltmore, who have been stranded aboard the International Space Station since June 2024. With the potential for an earlier return home due to a change in SpaceX's Crew 10 mission schedule, we discuss the challenges they faced during their extended stay in orbit.

2025 coming up on SpaceTime the odds
00:00:09.320 --> 00:00:11.430
narrowing for an Earth impact by the
00:00:11.440 --> 00:00:13.829
city killer asteroid looking at the
00:00:13.839 --> 00:00:16.950

NASA's stranded Starliner astronauts
00:00:19.600 --> 00:00:22.150
coming home earlier than thought all
00:00:22.160 --> 00:00:25.269
that and more coming up on

Nessa says there's now a 3.1% chance of
00:00:48.800 --> 00:00:51.990
asteroid 2024 yr4 slamming into the
00:00:52.000 --> 00:00:54.389
Earth on December the 22nd
00:00:54.399 --> 00:00:58.430
20132 that translates to odds of 1 in32
00:00:58.440 --> 00:01:01.670
up from the 1 in 43 or 2.3% chance of an
00:01:01.680 --> 00:01:03.630
impact earlier this month and roughly
00:01:03.640 --> 00:01:05.630
three times greater than the original
00:01:05.640 --> 00:01:08.789
estimate of one in 83 or 1.2% first
00:01:08.799 --> 00:01:12.310
calculated 4 weeks ago the 40 to 90 M
00:01:12.320 --> 00:01:13.910
wide asteroid is now the most
00:01:13.920 --> 00:01:15.990
threatening space rock this big ever
00:01:16.000 --> 00:01:18.550
recorded by modern forecasting
00:01:18.560 --> 00:01:20.429
astronomers have estimated its size
00:01:20.439 --> 00:01:24.390
based on its brightness 2024 yr4 is on
00:01:24.400 --> 00:01:26.710
an elongated elliptical orbit around the
00:01:26.720 --> 00:01:29.109
sun it's currently moving away from the
00:01:29.119 --> 00:01:31.630
earth making it more difficult to track
00:01:31.640 --> 00:01:34.429
but it will be back in December 2028
00:01:34.439 --> 00:01:35.910
where scientists will get a good look at
00:01:35.920 --> 00:01:38.550
it and be able to finalize its orbit and
00:01:38.560 --> 00:01:40.789
trajectory the last time an asteroid
00:01:40.799 --> 00:01:42.670
more than 30 m wide posed such a
00:01:42.680 --> 00:01:44.950
significant risk to Earth was apus back
00:01:44.960 --> 00:01:48.389
in 2004 when it briefly had a 2.7%
00:01:48.399 --> 00:01:51.230
chance of Earth impact in 2029 a
00:01:51.240 --> 00:01:53.030
possibility later ruled out by
00:01:53.040 --> 00:01:56.670
additional observations 2024 yr4 was
00:01:56.680 --> 00:01:58.990
first detected on December the 27th last
00:01:59.000 --> 00:02:00.830
year by the old source observatory in
00:02:00.840 --> 00:02:03.429
Chile the international asteroid warning
00:02:03.439 --> 00:02:05.590
Network issued an alarm on January the
00:02:05.600 --> 00:02:08.029
29th after the impact probability cross
00:02:08.039 --> 00:02:11.270
the 1% barrier the agency says if that
00:02:11.280 --> 00:02:13.750
risk Rises to over 10% it'll issue a
00:02:13.760 --> 00:02:15.630
formal warning leading to a
00:02:15.640 --> 00:02:17.630
recommendation for all United Nation
00:02:17.640 --> 00:02:18.990
members who have territories in the
00:02:19.000 --> 00:02:20.630
potential Impact Zone to start
00:02:20.640 --> 00:02:21.990
terrestrial
00:02:22.000 --> 00:02:24.229
preparedness the potential Earth impact
00:02:24.239 --> 00:02:26.470
site lies along an arc running from the
00:02:26.480 --> 00:02:28.430
central eastern Pacific Ocean across
00:02:28.440 --> 00:02:30.589
Northern South America in the Atlantic
00:02:30.599 --> 00:02:32.790
Ocean and equatorial Africa before
00:02:32.800 --> 00:02:35.390
finally ending in Northern India
00:02:35.400 --> 00:02:37.270
Professor Fred judan from the school of
00:02:37.280 --> 00:02:39.030
Earth and planetary Sciences at curtain
00:02:39.040 --> 00:02:40.790
University says that while the odds of
00:02:40.800 --> 00:02:42.949
an impact are still incredibly low the
00:02:42.959 --> 00:02:44.869
threat is not so small that it can be
00:02:44.879 --> 00:02:47.509
easily ignored well I think the latest
00:02:47.519 --> 00:02:49.630
news is really about the increase of
00:02:49.640 --> 00:02:51.790
probability that it's going to smash on
00:02:51.800 --> 00:02:54.949
Earth and uh it's still very very low I
00:02:54.959 --> 00:02:56.750
think I've read a news somewhere that
00:02:56.760 --> 00:02:59.509
there's even a 0.3% chance it would
00:02:59.519 --> 00:03:01.630
impact the moon so it's even lower we
00:03:01.640 --> 00:03:03.390
don't know whether it's a rocky body or
00:03:03.400 --> 00:03:05.390
a rubble pile I guess one of the
00:03:05.400 --> 00:03:07.030
interesting things is issues of
00:03:07.040 --> 00:03:09.350
planetary defense now we've had the dart
00:03:09.360 --> 00:03:11.550
Mission by NASA so we know a little bit
00:03:11.560 --> 00:03:13.509
about planetary defense from an asteroid
00:03:13.519 --> 00:03:15.789
don't we yeah so that that mission was
00:03:15.799 --> 00:03:17.550
absolutely excellent I mean it really
00:03:17.560 --> 00:03:21.229
showed us that by Smashing probe into
00:03:21.239 --> 00:03:24.309
asteroid we can push them but it also
00:03:24.319 --> 00:03:27.470
show us that we don't push them a lot
00:03:27.480 --> 00:03:30.070
right so it takes time to really push an
00:03:30.080 --> 00:03:32.070
asteroid out of the way because the
00:03:32.080 --> 00:03:34.350
probe the weight of the probe is fairly
00:03:34.360 --> 00:03:36.630
low and the mass of the asteroid is
00:03:36.640 --> 00:03:39.270
really high so you need to smash mini
00:03:39.280 --> 00:03:41.949
probe if you want to deflect a beginner
00:03:41.959 --> 00:03:45.750
asteroid now in the case of yr4 it's fa
00:03:45.760 --> 00:03:49.350
small it's between 40 m and 90 M that
00:03:49.360 --> 00:03:51.429
doesn't seem very big but that could
00:03:51.439 --> 00:03:54.069
level easily a city so that's something
00:03:54.079 --> 00:03:56.869
to consider pushing it away destroying
00:03:56.879 --> 00:03:59.869
all this safety measure that people are
00:03:59.879 --> 00:04:01.670
considering and you mentioned the
00:04:01.680 --> 00:04:03.509
structure and this structure is
00:04:03.519 --> 00:04:05.710
absolutely important the structure the
00:04:05.720 --> 00:04:07.789
nature of the asteroid it's very
00:04:07.799 --> 00:04:10.990
important to know what we can do to
00:04:11.000 --> 00:04:12.869
prevent an impact let me give you an
00:04:12.879 --> 00:04:15.589
example if it's a hard Rocky body and
00:04:15.599 --> 00:04:19.030
you try to impact a big enough object or
00:04:19.040 --> 00:04:22.030
even data nuclear bomb there's a huge
00:04:22.040 --> 00:04:23.909
chance that it's going to fragment now
00:04:23.919 --> 00:04:26.310
if it's a rubble pile asterid some study
00:04:26.320 --> 00:04:28.390
we did at curtain really show that if
00:04:28.400 --> 00:04:31.029
you detonate a nuclear B not at the
00:04:31.039 --> 00:04:33.950
surface but near the surface then it
00:04:33.960 --> 00:04:35.950
would withstand the sh and be pushed
00:04:35.960 --> 00:04:38.670
away and maybe this kind of measure this
00:04:38.680 --> 00:04:41.350
kind of approach is more efficient for
00:04:41.360 --> 00:04:44.510
deflecting and steroid very quickly than
00:04:44.520 --> 00:04:47.390
impacting probe over time because in the
00:04:47.400 --> 00:04:50.590
case of yr4 it's going to come back in
00:04:50.600 --> 00:04:54.510
2028 and then again in 2032 and that's
00:04:54.520 --> 00:04:56.790
when it could potentially impact so
00:04:56.800 --> 00:04:58.990
that's a really short amount of time to
00:04:59.000 --> 00:05:01.270
be able to push it out of the way that's
00:05:01.280 --> 00:05:03.310
why it's important to consider all the
00:05:03.320 --> 00:05:05.830
technique we can use to deflect this
00:05:05.840 --> 00:05:07.950
Aster yeah I remember we did an
00:05:07.960 --> 00:05:10.070
experiment like this on a small scale we
00:05:10.080 --> 00:05:12.390
had a boulder and we had a rubble pile
00:05:12.400 --> 00:05:15.390
and we fired a 223 rifle into each of
00:05:15.400 --> 00:05:17.230
them and hit the Boulder and it moved
00:05:17.240 --> 00:05:19.270
the boulder but when the bullet hit the
00:05:19.280 --> 00:05:22.270
rubble pile it just went right through
00:05:22.280 --> 00:05:24.350
and the rubble pile stayed where it was
00:05:24.360 --> 00:05:26.189
it didn't really move the rubble pile
00:05:26.199 --> 00:05:28.390
this is absolutely correct I mean that
00:05:28.400 --> 00:05:30.110
that that's something to to really keep
00:05:30.120 --> 00:05:32.909
in mind is like well if you detonate a
00:05:32.919 --> 00:05:35.309
device at the surface you would fragment
00:05:35.319 --> 00:05:37.590
the big one and then I don't know what
00:05:37.600 --> 00:05:39.510
it would do to the rubble Pile in space
00:05:39.520 --> 00:05:41.830
but the shock wave from something that
00:05:41.840 --> 00:05:44.510
is detonated sufficiently far away you
00:05:44.520 --> 00:05:45.749
know those people they make the
00:05:45.759 --> 00:05:48.230
calculation not too close not too far
00:05:48.240 --> 00:05:51.029
very brilliant engineering and if you do
00:05:51.039 --> 00:05:53.990
that then the verble pile will be easily
00:05:54.000 --> 00:05:56.670
pushed away without theoretically
00:05:56.680 --> 00:05:58.510
fragmenting it because obviously if you
00:05:58.520 --> 00:06:01.270
fragment the asteroid you transform a
00:06:01.280 --> 00:06:04.270
single ball into many many pieces it's
00:06:04.280 --> 00:06:06.510
like instead of a bullet yeah instead of
00:06:06.520 --> 00:06:09.749
a bullet now you got a shotgun spread so
00:06:09.759 --> 00:06:12.270
if it was supposed to be the ocean and
00:06:12.280 --> 00:06:14.150
now you fragment it and now it's going
00:06:14.160 --> 00:06:17.950
to rain on every cities on Earth uh well
00:06:17.960 --> 00:06:20.550
I mean you know not every along the fly
00:06:20.560 --> 00:06:22.830
path yeah yeah yeah along the fly path
00:06:22.840 --> 00:06:24.790
exactly then people are not going to be
00:06:24.800 --> 00:06:26.830
really happy you know less damage but
00:06:26.840 --> 00:06:28.950
still a lot of damage whereas before
00:06:28.960 --> 00:06:30.430
they would have been nothing for this
00:06:30.440 --> 00:06:32.390
particular City so there's really
00:06:32.400 --> 00:06:34.510
ethical concern like that to consider
00:06:34.520 --> 00:06:37.029
let's assume it's a solid body that's
00:06:37.039 --> 00:06:38.309
not going to wear burst that's going to
00:06:38.319 --> 00:06:39.589
cut through the atmosphere it's going to
00:06:39.599 --> 00:06:41.070
go all the way to the surface what sort
00:06:41.080 --> 00:06:43.309
of damage would something that's say 90
00:06:43.319 --> 00:06:45.469
M across do on the planet well that's
00:06:45.479 --> 00:06:47.950
why we call it the city killer not the
00:06:47.960 --> 00:06:50.790
country killer or or the Planet Killer
00:06:50.800 --> 00:06:53.110
because it's it's fairly small actually
00:06:53.120 --> 00:06:55.309
if people want to imagine what it would
00:06:55.319 --> 00:06:58.390
do it's like detonating a powerful
00:06:58.400 --> 00:07:00.749
nuclear bomb it it's the same an impact
00:07:00.759 --> 00:07:02.909
is an explosion it's not really like
00:07:02.919 --> 00:07:05.230
digging a hole it's just an explosion
00:07:05.240 --> 00:07:07.670
and well unfortunately you know in our
00:07:07.680 --> 00:07:10.070
history of humankind we detonate a lot
00:07:10.080 --> 00:07:12.189
of weapon as a test everywhere on the
00:07:12.199 --> 00:07:14.150
planet and uh you know depending where
00:07:14.160 --> 00:07:16.070
it's done it just leave a hole in the
00:07:16.080 --> 00:07:17.909
ground and the hole it would live it
00:07:17.919 --> 00:07:20.110
would be the size of Arizona crater the
00:07:20.120 --> 00:07:22.950
baringer crater which is about 1 kilm
00:07:22.960 --> 00:07:25.390
wide so that's not that big however a
00:07:25.400 --> 00:07:27.830
city would be completely leveled so here
00:07:27.840 --> 00:07:30.830
I I live in purse and we have roughly 2
00:07:30.840 --> 00:07:33.150
million inhabitant and the city would be
00:07:33.160 --> 00:07:34.909
completely destroyed now would have been
00:07:34.919 --> 00:07:36.990
a bit of warning before so people can
00:07:37.000 --> 00:07:39.150
evacuate but still it's really not nice
00:07:39.160 --> 00:07:41.390
to lose a beautiful city like this if
00:07:41.400 --> 00:07:44.430
you want but considering the bigger
00:07:44.440 --> 00:07:46.510
implication not much I mean you know
00:07:46.520 --> 00:07:48.110
it's not like you got to have a nuclear
00:07:48.120 --> 00:07:49.710
winter or anything like that plus
00:07:49.720 --> 00:07:51.710
something that people need to consider
00:07:51.720 --> 00:07:55.070
Earth is covered by about 70% water so
00:07:55.080 --> 00:07:57.070
you get 70% chance he going to land on
00:07:57.080 --> 00:08:00.550
the ocean and the land is about 2%
00:08:00.560 --> 00:08:03.790
inhabited in term of of cities I mean
00:08:03.800 --> 00:08:05.110
you know of course there's people living
00:08:05.120 --> 00:08:07.029
in Bush and stuff like that but in the
00:08:07.039 --> 00:08:09.270
term of city it's about 2% coverage so
00:08:09.280 --> 00:08:11.309
that's not there's very low Chance is
00:08:11.319 --> 00:08:13.270
going to impact on a city much more like
00:08:13.280 --> 00:08:14.950
in the outback or something like that
00:08:14.960 --> 00:08:16.909
well not that it's on the flat plan but
00:08:16.919 --> 00:08:19.309
like you you know related to Australia
00:08:19.319 --> 00:08:21.189
so the chance is really small and I
00:08:21.199 --> 00:08:23.189
would say for scientists you know we we
00:08:23.199 --> 00:08:25.110
almost would hope that it would impact
00:08:25.120 --> 00:08:27.430
so we could study how things happen
00:08:27.440 --> 00:08:28.909
because there's going to be so little
00:08:28.919 --> 00:08:30.869
consequence but again in middle of the
00:08:30.879 --> 00:08:33.350
ocean it's safe in the outback it's safe
00:08:33.360 --> 00:08:35.550
unfortunately if it's on a city that's
00:08:35.560 --> 00:08:37.269
really not good news and that's why we
00:08:37.279 --> 00:08:40.389
need to learn to deflect Aster maybe not
00:08:40.399 --> 00:08:42.990
for this particular case but you know
00:08:43.000 --> 00:08:45.350
for the training purpose not waiting the
00:08:45.360 --> 00:08:47.630
absolute that minute to know how to do
00:08:47.640 --> 00:08:51.310
something and our first test is you know
00:08:51.320 --> 00:08:52.990
is our first practice that's not
00:08:53.000 --> 00:08:55.269
reasonable I would think so using this
00:08:55.279 --> 00:08:58.030
opportunity maybe trying to deflect this
00:08:58.040 --> 00:09:00.030
one that would be interesting and I
00:09:00.040 --> 00:09:03.110
think uh I might be wrong but I think I
00:09:03.120 --> 00:09:05.910
read online that China is interested by
00:09:05.920 --> 00:09:07.870
the prospect of doing that having their
00:09:07.880 --> 00:09:11.350
own dart Mission using another asteroid
00:09:11.360 --> 00:09:13.509
and maybe this one as well so we'll see
00:09:13.519 --> 00:09:15.190
how it goes the other option of course
00:09:15.200 --> 00:09:17.230
is that it is the rubble pile and that
00:09:17.240 --> 00:09:19.870
makes me think more of the tangus like
00:09:19.880 --> 00:09:22.110
event I know what you're saying uh like
00:09:22.120 --> 00:09:24.470
like a big explosion in the sky it's
00:09:24.480 --> 00:09:27.550
still like tangus or chela blinks chela
00:09:27.560 --> 00:09:29.670
blinks was really small it was a small
00:09:29.680 --> 00:09:32.230
was a 10 m in diameter but still you
00:09:32.240 --> 00:09:34.350
know broke a lot of Windows and things
00:09:34.360 --> 00:09:36.509
like that but impact a St like that
00:09:36.519 --> 00:09:38.949
explosion it's really a exponential
00:09:38.959 --> 00:09:42.630
scale so 90 m is not nine times more
00:09:42.640 --> 00:09:45.230
powerful is so many more time powerful
00:09:45.240 --> 00:09:48.069
like I said you know yes 500 time
00:09:48.079 --> 00:09:49.910
yoshima or something like that so that
00:09:49.920 --> 00:09:52.630
that's really decent Rubble pile or not
00:09:52.640 --> 00:09:54.910
I think that would be the same thing if
00:09:54.920 --> 00:09:57.350
the explosion touch the ground okay it's
00:09:57.360 --> 00:09:59.550
one thing but if it explodes in midair
00:09:59.560 --> 00:10:01.630
with the power of nuclear bomb that has
00:10:01.640 --> 00:10:03.750
exactly the same effect on a city that
00:10:03.760 --> 00:10:06.350
still Level it the same way so Rubble
00:10:06.360 --> 00:10:08.630
pile or not it's more for how we going
00:10:08.640 --> 00:10:10.910
to deflect it which is important rather
00:10:10.920 --> 00:10:12.670
than how it's going to impact on Earth
00:10:12.680 --> 00:10:14.509
in my opinion that's Professor Fred
00:10:14.519 --> 00:10:16.190
Jordan from the school of Earth and
00:10:16.200 --> 00:10:19.350
planetary Sciences at curtain University
00:10:19.360 --> 00:10:22.829
and this SpaceTime still to come looking
00:10:22.839 --> 00:10:24.630
at the origins of the moon's Grand
00:10:24.640 --> 00:10:27.389
Canyons and nessa's Stranded astronauts
00:10:27.399 --> 00:10:29.030
now likely to come home a little bit
00:10:29.040 --> 00:10:31.310
early ier than last planned all that and
00:10:31.320 --> 00:10:37.210
more still to come on
00:10:37.220 --> 00:10:48.509
[Music]
00:10:48.519 --> 00:10:51.110
SpaceTime a new study has concluded that
00:10:51.120 --> 00:10:53.629
two gigantic Canyons on the moon were
00:10:53.639 --> 00:10:55.790
most likely carved out by streams of
00:10:55.800 --> 00:10:58.150
impacting asteroids over a space of just
00:10:58.160 --> 00:11:00.829
10 minutes the new findings reported in
00:11:00.839 --> 00:11:02.710
the journal Nature Communications are
00:11:02.720 --> 00:11:05.069
providing fresh insights into an area of
00:11:05.079 --> 00:11:06.829
the Moon which will be crucial in
00:11:06.839 --> 00:11:09.829
upcoming lunar missions the Schrodinger
00:11:09.839 --> 00:11:12.190
impact Basin with an estimated age of
00:11:12.200 --> 00:11:14.829
3.81 billion years is located in the
00:11:14.839 --> 00:11:18.230
outer margin of the moon's 2,400 km
00:11:18.240 --> 00:11:21.269
diameter South Pole atken Basin that's
00:11:21.279 --> 00:11:23.110
one of the largest impact basins in the
00:11:23.120 --> 00:11:25.629
solar system the Schrodinger Basin
00:11:25.639 --> 00:11:27.750
itself is surrounded by canyons and
00:11:27.760 --> 00:11:30.310
Ravines created by by streaks of Rocky
00:11:30.320 --> 00:11:32.350
debris known as ejector rays that were
00:11:32.360 --> 00:11:35.389
flung out during an impact event two
00:11:35.399 --> 00:11:37.629
spectacular canyons in the complex are
00:11:37.639 --> 00:11:40.790
valis Schrodinger and valis plank these
00:11:40.800 --> 00:11:42.829
massive canyons are comparable in size
00:11:42.839 --> 00:11:44.750
to North America's Grand Canyon with
00:11:44.760 --> 00:11:47.790
Schrodinger measuring some 270 km long
00:11:47.800 --> 00:11:50.750
and 2.7 km deep while plank is even
00:11:50.760 --> 00:11:55.790
larger at 280 km long and 3.5 km deep
00:11:55.800 --> 00:11:57.350
however the exact nature of their
00:11:57.360 --> 00:11:59.230
formation had always been unclear on
00:11:59.240 --> 00:12:01.870
until now the new research is based on
00:12:01.880 --> 00:12:03.790
images of the moon's surface used to
00:12:03.800 --> 00:12:06.110
generate new topographic maps which were
00:12:06.120 --> 00:12:08.069
then used to calculate flow directions
00:12:08.079 --> 00:12:10.269
and speed of the debris ejected during
00:12:10.279 --> 00:12:12.750
the canyon forming impact event and
00:12:12.760 --> 00:12:14.949
these data could then be used to model
00:12:14.959 --> 00:12:17.629
how the ejector rays were formed the
00:12:17.639 --> 00:12:19.430
study's authors proposed that these
00:12:19.440 --> 00:12:21.670
lunar Grand Canyons were carved out of
00:12:21.680 --> 00:12:24.230
the lunar crust in less than 10 minutes
00:12:24.240 --> 00:12:26.189
by ejector traveling at speeds of
00:12:26.199 --> 00:12:29.870
between 0.95 and 1.28 km
00:12:29.880 --> 00:12:32.430
m/s they calculate that the energy
00:12:32.440 --> 00:12:34.389
needed to create these massive Canyons
00:12:34.399 --> 00:12:36.389
would have been over 130 times the
00:12:36.399 --> 00:12:38.150
energy of all the current Global
00:12:38.160 --> 00:12:41.110
inventory of nuclear weapons rather than
00:12:41.120 --> 00:12:42.910
flying out symmetrically the work
00:12:42.920 --> 00:12:44.310
suggest that the majority of the
00:12:44.320 --> 00:12:46.389
excavated debris was asymmetrically
00:12:46.399 --> 00:12:48.550
distributed away from the poles the
00:12:48.560 --> 00:12:50.829
shrer impact Basin is close to the
00:12:50.839 --> 00:12:52.710
exploration zone for the upcoming
00:12:52.720 --> 00:12:55.550
Artemus man moon mission so these
00:12:55.560 --> 00:12:56.790
findings will have important
00:12:56.800 --> 00:12:59.189
implications for future Luna missions
00:12:59.199 --> 00:13:00.750
possibly offering insights into the
00:13:00.760 --> 00:13:03.949
composition of potential Landing zones
00:13:03.959 --> 00:13:07.430
this SpaceTime still to come Nas's
00:13:07.440 --> 00:13:09.710
stranded astronauts Cy Williams and
00:13:09.720 --> 00:13:11.550
Butch Wilmore who have been stuck aboard
00:13:11.560 --> 00:13:13.430
the International Space Station since
00:13:13.440 --> 00:13:15.550
June last year could be returning home
00:13:15.560 --> 00:13:17.790
earlier than currently planned and later
00:13:17.800 --> 00:13:19.910
in the science report it's official
00:13:19.920 --> 00:13:22.629
linia has finally arrived in the Eastern
00:13:22.639 --> 00:13:25.030
Pacific Ocean all that and more still to
00:13:25.040 --> 00:13:39.180
come on SpaceTime
00:13:39.190 --> 00:13:42.269
[Music]
00:13:42.279 --> 00:13:44.150
Nessa astronauts Sunni Williams and
00:13:44.160 --> 00:13:46.069
Butch Wilmore have been stranded aboard
00:13:46.079 --> 00:13:47.750
the International Space Station since
00:13:47.760 --> 00:13:49.710
June last year could end up returning
00:13:49.720 --> 00:13:52.110
home earlier than currently planned
00:13:52.120 --> 00:13:53.829
that's because SpaceX is looking at
00:13:53.839 --> 00:13:55.749
swapping the dragon capsules for its
00:13:55.759 --> 00:13:57.910
next twom man missions to the orbiting
00:13:57.920 --> 00:14:00.350
Outpost the that would see the crew 10
00:14:00.360 --> 00:14:02.749
Mission launch on March 12 two weeks
00:14:02.759 --> 00:14:05.350
earlier than previously slated Wilmore
00:14:05.360 --> 00:14:07.069
and Williams have now been stranded on
00:14:07.079 --> 00:14:09.389
the space station for over 8 months on
00:14:09.399 --> 00:14:11.110
what should have been an 8 to 10day
00:14:11.120 --> 00:14:12.990
mission after problems developed with
00:14:13.000 --> 00:14:14.870
the thrusters aboard their Boeing styl
00:14:14.880 --> 00:14:16.749
on a spacecraft which was undertaking
00:14:16.759 --> 00:14:19.310
its first man test flight NASA were
00:14:19.320 --> 00:14:21.030
concerned about safety issues with the
00:14:21.040 --> 00:14:23.310
spacecraft and Boeing eventually decided
00:14:23.320 --> 00:14:25.230
to return the spacecraft to Earth
00:14:25.240 --> 00:14:27.870
unmanned it ended up safely landing on
00:14:27.880 --> 00:14:30.550
the Whit Sand Missile range after the
00:14:30.560 --> 00:14:32.829
new crew 10 arrives on station Wilmore
00:14:32.839 --> 00:14:34.389
and Williams will return to Earth with
00:14:34.399 --> 00:14:36.310
the current crew 9 team aboard their
00:14:36.320 --> 00:14:38.069
dragon capture which will be fitted with
00:14:38.079 --> 00:14:40.150
two additional couches for the
00:14:40.160 --> 00:14:42.200
astronauts this is
00:14:42.210 --> 00:14:57.069
[Music]
00:14:57.079 --> 00:14:59.310
spacetime and time now to take a a brief
00:14:59.320 --> 00:15:00.710
look at some of the other stories making
00:15:00.720 --> 00:15:02.870
news in science this week with a science
00:15:02.880 --> 00:15:06.350
report well after 7 months of waiting L
00:15:06.360 --> 00:15:08.430
the cooler and wetter sister of El Nino
00:15:08.440 --> 00:15:10.350
has finally arrived in the Eastern
00:15:10.360 --> 00:15:13.150
Pacific Ocean however a report by Noah
00:15:13.160 --> 00:15:14.310
the national oceanographic and
00:15:14.320 --> 00:15:15.990
Atmospheric administration's climate
00:15:16.000 --> 00:15:18.269
Prediction Center has warned that Lenin
00:15:18.279 --> 00:15:20.350
may not stick around for very long with
00:15:20.360 --> 00:15:22.430
the Pacific likely to return to neutral
00:15:22.440 --> 00:15:25.310
conditions either next month or in April
00:15:25.320 --> 00:15:27.110
part of the elino Southern oscillation
00:15:27.120 --> 00:15:29.550
or Enzo cycle Lenin appears when
00:15:29.560 --> 00:15:32.189
energized easterly Trade Winds intensify
00:15:32.199 --> 00:15:34.030
the upwelling of cooler water from the
00:15:34.040 --> 00:15:36.030
depths of the Eastern tropical Pacific
00:15:36.040 --> 00:15:38.069
causing a large scale cooling of surface
00:15:38.079 --> 00:15:39.470
waters in the eastern and Central
00:15:39.480 --> 00:15:41.949
Pacific Ocean near the equator the
00:15:41.959 --> 00:15:43.910
stronger than usual Trade Winds also
00:15:43.920 --> 00:15:46.189
push warmer equator Waters westwards
00:15:46.199 --> 00:15:48.670
towards Australia and Asia and this
00:15:48.680 --> 00:15:50.389
dramatic cooling of the ocean surface
00:15:50.399 --> 00:15:52.309
layers affects the Atmosphere by
00:15:52.319 --> 00:15:54.550
modifying moisture content right across
00:15:54.560 --> 00:15:57.350
the Pacific the new report has confirmed
00:15:57.360 --> 00:16:00.470
that Lin conditions are now present it
00:16:00.480 --> 00:16:03.110
measured sea surface temperature 0.7 de
00:16:03.120 --> 00:16:05.269
C below average in an area of the
00:16:05.279 --> 00:16:07.910
tropical Pacific known as the Nino 3.4
00:16:07.920 --> 00:16:10.230
region and the signature of Lenin is
00:16:10.240 --> 00:16:11.829
also visible in the Central and Eastern
00:16:11.839 --> 00:16:13.749
Pacific Ocean as areas of lower than
00:16:13.759 --> 00:16:15.470
average water levels that's because
00:16:15.480 --> 00:16:17.470
cooler water contracts lowering sea
00:16:17.480 --> 00:16:20.590
levels conversely warmer water expands
00:16:20.600 --> 00:16:23.350
increasing them linia causes shifts in
00:16:23.360 --> 00:16:25.470
the path of mid latitude jet streams in
00:16:25.480 --> 00:16:27.749
ways that intensify rainfall in some
00:16:27.759 --> 00:16:30.189
regions and bring drought to others in
00:16:30.199 --> 00:16:32.230
the Western Pacific for example rainfall
00:16:32.240 --> 00:16:34.269
usually increases over Australia and
00:16:34.279 --> 00:16:36.550
Indonesia clouds and rainfall become
00:16:36.560 --> 00:16:38.069
more sporadic over the Central and
00:16:38.079 --> 00:16:40.230
Eastern Pacific Ocean which can lead to
00:16:40.240 --> 00:16:42.949
dry conditions in Brazil Argentina and
00:16:42.959 --> 00:16:45.269
other parts of South America and wter
00:16:45.279 --> 00:16:47.749
conditions over Central America in North
00:16:47.759 --> 00:16:49.590
America cooler and stormier conditions
00:16:49.600 --> 00:16:50.990
often sit in across the Pacific
00:16:51.000 --> 00:16:52.870
Northwest while the weather typically
00:16:52.880 --> 00:16:54.870
becomes warmer and drier across the
00:16:54.880 --> 00:16:56.710
Southern United States and across
00:16:56.720 --> 00:16:59.309
northern Mexico
00:16:59.319 --> 00:17:01.550
a new study warns that if you lose your
00:17:01.560 --> 00:17:03.870
sense of smell or taste in adulthood
00:17:03.880 --> 00:17:05.949
especially for saltiness and sourness
00:17:05.959 --> 00:17:08.230
you may well be a risk of dying
00:17:08.240 --> 00:17:10.549
prematurely the findings reported in the
00:17:10.559 --> 00:17:11.909
Journal of the American Medical
00:17:11.919 --> 00:17:15.069
Association followed 7,340 people for
00:17:15.079 --> 00:17:18.590
around 6 to 7 years 662 of whom reported
00:17:18.600 --> 00:17:21.110
losing their sense of taste now during
00:17:21.120 --> 00:17:23.829
the study period 1,1 of those
00:17:23.839 --> 00:17:25.990
participating died resulting in a
00:17:26.000 --> 00:17:28.909
background chance of dying of 14% or
00:17:28.919 --> 00:17:31.270
around one in seven people but for those
00:17:31.280 --> 00:17:33.070
who lost their sense of taste the risk
00:17:33.080 --> 00:17:34.870
of dying during the study period was
00:17:34.880 --> 00:17:38.590
around 47% higher or around 1 in five
00:17:38.600 --> 00:17:40.549
the biggest increases in death risk were
00:17:40.559 --> 00:17:42.230
among those who stopped being able to
00:17:42.240 --> 00:17:44.870
sense salty tastes as well as among men
00:17:44.880 --> 00:17:46.830
who stopped being able to taste sourness
00:17:46.840 --> 00:17:48.470
and among women who sto being able to
00:17:48.480 --> 00:17:51.190
taste bitterness and that increased risk
00:17:51.200 --> 00:17:53.230
of death was seen even among people who
00:17:53.240 --> 00:17:54.870
had lost their sense of taste but whose
00:17:54.880 --> 00:17:58.310
sense of smell had remained intact so it
00:17:58.320 --> 00:18:00.230
seems although it's yet to be proven
00:18:00.240 --> 00:18:02.590
that a loss in taste could serve as a
00:18:02.600 --> 00:18:04.549
simple way of scanning high-risk
00:18:04.559 --> 00:18:06.710
populations in order to determine who's
00:18:06.720 --> 00:18:09.549
at risk of dying prematurely now all
00:18:09.559 --> 00:18:11.470
we've got to do is work out why the
00:18:11.480 --> 00:18:13.789
association seems to be
00:18:13.799 --> 00:18:16.510
there paleontologists have Rewritten the
00:18:16.520 --> 00:18:18.750
evolution of dinosaurs after discovering
00:18:18.760 --> 00:18:20.669
fossils of the world's oldest known Mega
00:18:20.679 --> 00:18:22.909
raptoid and the first evidence of
00:18:22.919 --> 00:18:26.310
karadon Sids in Australia the findings
00:18:26.320 --> 00:18:27.669
reported in the Journal of vertebrate
00:18:27.679 --> 00:18:29.909
paleontology has has changed the history
00:18:29.919 --> 00:18:32.149
of theropod dinosaurs uncovering a
00:18:32.159 --> 00:18:34.789
predator hierarchy unique to Cretaceous
00:18:34.799 --> 00:18:37.350
Australia the research describes five
00:18:37.360 --> 00:18:39.190
therapod fossils discovered along
00:18:39.200 --> 00:18:40.909
Victorious Coastline Unearthed in the
00:18:40.919 --> 00:18:43.870
upper stres Lei group between 121.4 and
00:18:43.880 --> 00:18:46.710
118 million years ago and from the umel
00:18:46.720 --> 00:18:49.590
formation on the Otway Coast between 113
00:18:49.600 --> 00:18:52.909
and 108 million years ago these fossils
00:18:52.919 --> 00:18:55.190
are offering scientists new insights
00:18:55.200 --> 00:18:58.110
into Victoria's ancient ecosystems it
00:18:58.120 --> 00:19:00.870
was a time dominated by large powerful 6
00:19:00.880 --> 00:19:04.230
to 7 m long mear Rapids smaller 2 to 4 M
00:19:04.240 --> 00:19:07.390
long karadon SIDS and small agile meter
00:19:07.400 --> 00:19:10.110
long Southern Raptors the discovery also
00:19:10.120 --> 00:19:12.510
shows how Victorious Predator hierarchy
00:19:12.520 --> 00:19:15.070
diverge from South America where karadon
00:19:15.080 --> 00:19:17.390
aaids reach Tyrannosaurus Rex likee
00:19:17.400 --> 00:19:20.789
sizes up to 13 M toing over the mega
00:19:20.799 --> 00:19:23.549
raptoid but in Victoria the roles were
00:19:23.559 --> 00:19:25.950
reversed highlighting the uniqueness of
00:19:25.960 --> 00:19:29.710
Australia's Cretaceous ecosystem
00:19:29.720 --> 00:19:31.390
a fraudster who claimed to be able to
00:19:31.400 --> 00:19:33.270
cure a range of illnesses using a
00:19:33.280 --> 00:19:35.230
so-called slapping therapy has been
00:19:35.240 --> 00:19:37.669
jailed for 10 years in the UK after one
00:19:37.679 --> 00:19:40.390
of his patients died Tim mum from
00:19:40.400 --> 00:19:42.310
Australian skeptic says the con man had
00:19:42.320 --> 00:19:44.390
used the same scam in Australia where
00:19:44.400 --> 00:19:46.390
another patient died sling therapy is
00:19:46.400 --> 00:19:48.789
one of those treatments for disease Etc
00:19:48.799 --> 00:19:50.630
which people make up oh I've got a good
00:19:50.640 --> 00:19:52.270
idea maybe we should try this there is
00:19:52.280 --> 00:19:54.110
something close to it but not quite the
00:19:54.120 --> 00:19:55.350
same has been around a while called
00:19:55.360 --> 00:19:57.110
tapping therapy you tap parts of the
00:19:57.120 --> 00:19:59.390
body just tapping with sort of like two
00:19:59.400 --> 00:20:01.070
fingers and that's supposed to help your
00:20:01.080 --> 00:20:02.549
health no evidence of that but there's
00:20:02.559 --> 00:20:03.990
the one which is a lot more serious than
00:20:04.000 --> 00:20:06.149
that it's slapping as in literally
00:20:06.159 --> 00:20:07.990
slapping the face and slapping the body
00:20:08.000 --> 00:20:09.909
hard and it's sort of developed by a
00:20:09.919 --> 00:20:12.750
Chinese fellow named honi XO and he was
00:20:12.760 --> 00:20:15.350
doing it in the UK he came to Australia
00:20:15.360 --> 00:20:17.470
and was doing it there what He suggests
00:20:17.480 --> 00:20:18.870
is is that this is better than
00:20:18.880 --> 00:20:20.789
medication this has a real effect he
00:20:20.799 --> 00:20:22.270
says and it's better than medication and
00:20:22.280 --> 00:20:24.710
in some instances specific instances
00:20:24.720 --> 00:20:27.110
people who need insulin have been told
00:20:27.120 --> 00:20:28.750
not to take it and when you don't take
00:20:28.760 --> 00:20:30.669
insulin and you have a bad case of
00:20:30.679 --> 00:20:32.470
diabetes it can have immediate or very
00:20:32.480 --> 00:20:34.710
short almost instantaneous effects and
00:20:34.720 --> 00:20:36.230
what happens is that if you continue not
00:20:36.240 --> 00:20:37.630
to use it it can be fatal and that's
00:20:37.640 --> 00:20:39.230
exactly what happened in Australia with
00:20:39.240 --> 00:20:41.630
a young lad I think was 10 years old his
00:20:41.640 --> 00:20:42.909
parents were going through the slapping
00:20:42.919 --> 00:20:44.270
I don't know if the kid was but the
00:20:44.280 --> 00:20:45.830
parents wereth and this person was
00:20:45.840 --> 00:20:47.789
suggesting don't take insulin it's bad
00:20:47.799 --> 00:20:49.549
for you the slapping will do all the
00:20:49.559 --> 00:20:51.190
things you needs to do so they stopped
00:20:51.200 --> 00:20:52.669
the insulin for the kid and then pretty
00:20:52.679 --> 00:20:54.350
soon within a few days he was rushed off
00:20:54.360 --> 00:20:55.950
the hospital and he died in a most
00:20:55.960 --> 00:20:57.950
agonizing horrible way you start off
00:20:57.960 --> 00:21:00.669
vomiting that coughing up bile all sorts
00:21:00.679 --> 00:21:02.390
of terrible things happened so he was
00:21:02.400 --> 00:21:04.470
charged in Australia he was found guilty
00:21:04.480 --> 00:21:06.710
sentenced for 10 years but he got off on
00:21:06.720 --> 00:21:08.750
appeal mainly because of of legal
00:21:08.760 --> 00:21:10.350
technicality not because he was not
00:21:10.360 --> 00:21:11.990
guilty of slapping in the way but just
00:21:12.000 --> 00:21:14.269
that saying the trial wasn't exactly as
00:21:14.279 --> 00:21:15.430
it should have been and therefore
00:21:15.440 --> 00:21:16.750
they're going to have a retrial but in
00:21:16.760 --> 00:21:18.590
the meantime he had actually moved to
00:21:18.600 --> 00:21:19.990
England and was doing the same thing
00:21:20.000 --> 00:21:21.269
there and with the same result of
00:21:21.279 --> 00:21:22.950
another older woman there who was
00:21:22.960 --> 00:21:25.390
suffering from diabetes and she thought
00:21:25.400 --> 00:21:27.230
he was a messenger from God which is the
00:21:27.240 --> 00:21:29.430
way he portrays himself and and same
00:21:29.440 --> 00:21:32.230
problem insulin stopped and dies in in a
00:21:32.240 --> 00:21:34.710
terribly agonizing way so he's moved
00:21:34.720 --> 00:21:36.470
around from place to place and doing the
00:21:36.480 --> 00:21:38.070
same sort of thing and now been thrown
00:21:38.080 --> 00:21:40.110
in jail in the UK sounds like a silly
00:21:40.120 --> 00:21:41.310
thing seconding someone for medical
00:21:41.320 --> 00:21:42.909
reasons yeah you get a red cheek and
00:21:42.919 --> 00:21:44.630
might be a bit painful to you know what
00:21:44.640 --> 00:21:46.230
harm can it do well it can kill you
00:21:46.240 --> 00:21:51.200
