This episode of SpaceTime delves into the latest revelations in the cosmos, exploring groundbreaking theories about dark matter and the future of lunar exploration.
New Insights into Dark Matter
Astronomers have made a significant breakthrough in understanding dark matter, revealing a potential new type of less massive dark matter at the center of the Milky Way. This study, published in Physical Review Letters, suggests that huge clouds of positively charged hydrogen may be linked to this elusive substance. The findings challenge existing models of dark matter, proposing that lighter particles may be responsible for unexplained chemical reactions observed in the galactic center.
Lunar Gateway Space Station Takes Shape
In an exciting development for lunar exploration, the first habitation module for the Lunar Gateway Space Station has arrived in the United States. Known as the Habitation and Logistics Outpost (HALO), this module will serve as a command hub for future missions to the Moon and Mars. We discuss the integration of HALO with the Power and Propulsion Element and the implications for the Artemis program.
Space Junk Threatens the ISS
We also cover the alarming increase in space debris, as NASA is forced to maneuver the International Space Station to avoid a potential collision with fragments of a Chinese rocket. This ongoing issue highlights the growing challenges of maintaining a safe orbital environment for astronauts aboard the ISS.

This is Spacetime series 28, episode 58
00:00:03.360 --> 00:00:05.710
for broadcast on the 14th of May,
00:00:05.720 --> 00:00:09.270
2025. Coming up on Spaceime, is there a
00:00:09.280 --> 00:00:11.270
new kind of dark matter in the galactic
00:00:11.280 --> 00:00:13.830
center? The Luna Gateway Space Station's
00:00:13.840 --> 00:00:15.749
first habitation module arrives in the
00:00:15.759 --> 00:00:18.470
United States, and more space junk
00:00:18.480 --> 00:00:20.029
threatens the International Space
00:00:20.039 --> 00:00:23.269
Station. All that and more coming up on
00:00:23.279 --> 00:00:25.429
Spaceime.
00:00:25.439 --> 00:00:29.490
Welcome to Spaceime with Stuart Garry.
00:00:29.500 --> 00:00:36.360
[Music]
00:00:44.719 --> 00:00:46.630
Astronomers have uncovered a mysterious
00:00:46.640 --> 00:00:48.150
phenomenon in the center of the Milky
00:00:48.160 --> 00:00:50.549
Way galaxy which could reveal a new
00:00:50.559 --> 00:00:52.630
different kind of less massive dark
00:00:52.640 --> 00:00:55.189
matter. Dark matter is a mysterious
00:00:55.199 --> 00:00:57.110
invisible substance which makes up some
00:00:57.120 --> 00:00:59.750
85% of all the mass in the universe. Yet
00:00:59.760 --> 00:01:02.069
scientists have absolutely no idea what
00:01:02.079 --> 00:01:04.869
it is. They know it exists because they
00:01:04.879 --> 00:01:06.710
can see its gravitational effect on
00:01:06.720 --> 00:01:08.950
surrounding space, keeping galaxies from
00:01:08.960 --> 00:01:10.789
spinning apart as they revolve and
00:01:10.799 --> 00:01:13.750
bending light from distant objects. Now,
00:01:13.760 --> 00:01:16.149
in a firstofits-kind study, scientists
00:01:16.159 --> 00:01:17.429
have taken a step closer to
00:01:17.439 --> 00:01:19.350
understanding this elusive substance by
00:01:19.360 --> 00:01:21.030
taking another look at a previously
00:01:21.040 --> 00:01:23.030
dismissed candidate for dark matter that
00:01:23.040 --> 00:01:25.030
could be behind unexplained chemical
00:01:25.040 --> 00:01:27.109
reactions seen taking place at the
00:01:27.119 --> 00:01:29.270
center of the Milky Way. One of the
00:01:29.280 --> 00:01:31.350
studies authors, Shambalaji from King's
00:01:31.360 --> 00:01:33.510
College London, says the key could be
00:01:33.520 --> 00:01:35.510
huge clouds of positively charged
00:01:35.520 --> 00:01:37.510
hydrogen located at the center of our
00:01:37.520 --> 00:01:39.670
galaxy. Their existence has been a
00:01:39.680 --> 00:01:41.670
mystery for decades because normally the
00:01:41.680 --> 00:01:44.630
gas should be neutral. So that raises
00:01:44.640 --> 00:01:46.230
the question of what's supplying enough
00:01:46.240 --> 00:01:47.910
energy to knock all the negatively
00:01:47.920 --> 00:01:50.270
charged electrons out of these
00:01:50.280 --> 00:01:52.550
clouds. Says the energy signatures
00:01:52.560 --> 00:01:54.389
radiating from this part of the galaxy
00:01:54.399 --> 00:01:56.389
suggest that there's a constant roaring
00:01:56.399 --> 00:01:58.950
source of power doing that and his data
00:01:58.960 --> 00:02:00.310
suggests that it might well will be
00:02:00.320 --> 00:02:02.230
coming from a much lighter form of dark
00:02:02.240 --> 00:02:03.910
matter than what current models are
00:02:03.920 --> 00:02:06.310
considering. Now, most established
00:02:06.320 --> 00:02:08.469
hypotheses designed to explain dark
00:02:08.479 --> 00:02:10.389
matter describe it as likely being
00:02:10.399 --> 00:02:12.470
weakly interacting massive particles or
00:02:12.480 --> 00:02:14.949
wimps, tiny subatomic particles which
00:02:14.959 --> 00:02:16.710
pass through regular matter without much
00:02:16.720 --> 00:02:18.150
interaction, and that makes them
00:02:18.160 --> 00:02:20.710
extremely hard to detect. However, this
00:02:20.720 --> 00:02:22.390
new study reported in the journal
00:02:22.400 --> 00:02:24.470
Physical Review Letters has potentially
00:02:24.480 --> 00:02:26.869
revived another type of dark matter, one
00:02:26.879 --> 00:02:28.949
with far lower mass than your
00:02:28.959 --> 00:02:31.110
traditional WIMP. The authors think
00:02:31.120 --> 00:02:32.790
these tiny dark matter particles are
00:02:32.800 --> 00:02:34.869
crashing into each other and as a result
00:02:34.879 --> 00:02:36.869
are producing new charged particles in a
00:02:36.879 --> 00:02:39.190
process called annihilation. And it's
00:02:39.200 --> 00:02:41.030
these newly produced charged particles
00:02:41.040 --> 00:02:42.949
that are subsequently ionizing the
00:02:42.959 --> 00:02:45.430
hydrogen gas. Previous attempts to
00:02:45.440 --> 00:02:47.589
explain the ionization process in these
00:02:47.599 --> 00:02:49.670
gas clouds has always relied on cosmic
00:02:49.680 --> 00:02:51.910
rays, fast and energetic particles which
00:02:51.920 --> 00:02:54.229
travel throughout the universe. However,
00:02:54.239 --> 00:02:56.630
that explanation has some difficulties.
00:02:56.640 --> 00:02:58.309
For example, the energy signature
00:02:58.319 --> 00:03:00.390
recorded from observations of this area
00:03:00.400 --> 00:03:02.070
known as the central molecular zone
00:03:02.080 --> 00:03:03.910
isn't large enough to be attributed to
00:03:03.920 --> 00:03:06.790
cosmic rays. And such a process doesn't
00:03:06.800 --> 00:03:09.270
seem to be possible with wimps either.
00:03:09.280 --> 00:03:10.869
So the research team have been left with
00:03:10.879 --> 00:03:13.190
an explanation that this energy source
00:03:13.200 --> 00:03:15.030
which is causing the annihilation is
00:03:15.040 --> 00:03:16.949
slower than a cosmic ray and less
00:03:16.959 --> 00:03:19.750
massive than a wimp. Belgi says the
00:03:19.760 --> 00:03:21.910
search for dark matter has seen a lot of
00:03:21.920 --> 00:03:23.750
experiments here on Earth and none of
00:03:23.760 --> 00:03:26.070
them have produced anything conclusive.
00:03:26.080 --> 00:03:28.070
But by using gas at the galactic center
00:03:28.080 --> 00:03:29.910
for a different kind of observation,
00:03:29.920 --> 00:03:31.990
astronomers might be getting straight to
00:03:32.000 --> 00:03:34.309
the source. And the data is telling
00:03:34.319 --> 00:03:36.229
scientists that dark matter could
00:03:36.239 --> 00:03:38.229
potentially be a lot lighter than they
00:03:38.239 --> 00:03:40.789
thought. The finding may simultaneously
00:03:40.799 --> 00:03:43.030
explain wider mysteries in our galaxy as
00:03:43.040 --> 00:03:45.110
well, such as a specific type of X-ray
00:03:45.120 --> 00:03:46.550
observation found at the center of the
00:03:46.560 --> 00:03:48.949
Milky Way, known as the 511 kilo
00:03:48.959 --> 00:03:51.509
electron volt emission line. See, this
00:03:51.519 --> 00:03:53.350
specific energy signature could also be
00:03:53.360 --> 00:03:55.190
due to the same low mass dark matter
00:03:55.200 --> 00:03:56.830
colliding and producing charged
00:03:56.840 --> 00:03:58.710
particles. It's an interesting
00:03:58.720 --> 00:04:00.949
hypothesis and it follows a trend where
00:04:00.959 --> 00:04:02.710
other low mass candidates for dark
00:04:02.720 --> 00:04:05.429
matter have already been postulated.
00:04:05.439 --> 00:04:08.869
This is spaceime still to come. The
00:04:08.879 --> 00:04:10.710
Lunar Gateway Space Station's first
00:04:10.720 --> 00:04:12.710
habitation module arrives in the United
00:04:12.720 --> 00:04:14.949
States ready for final fit out and then
00:04:14.959 --> 00:04:17.030
it's up to orbit. And speaking of space
00:04:17.040 --> 00:04:19.189
stations, more space junk is threatening
00:04:19.199 --> 00:04:21.270
the International Space Station. NASA
00:04:21.280 --> 00:04:23.270
have been forced to take evasive action.
00:04:23.280 --> 00:04:27.469
All that and more still to come on
00:04:27.479 --> 00:04:29.670
Spaceime. Okay, let's take a break from
00:04:29.680 --> 00:04:31.350

And now it's back to our show.
00:06:28.230 --> 00:06:32.070
[Music]
00:06:32.080 --> 00:06:34.070
The first habitation module for the new
00:06:34.080 --> 00:06:36.309
Luna Gateway Space Station has finally
00:06:36.319 --> 00:06:38.950
arrived in the United States. Known as
00:06:38.960 --> 00:06:41.270
the habitation and logistics outpost or
00:06:41.280 --> 00:06:43.590
Halo module, it'll be a core element of
00:06:43.600 --> 00:06:45.510
the Luna Gateway Space Station, which
00:06:45.520 --> 00:06:47.670
will be humanity's first Luna space
00:06:47.680 --> 00:06:49.990
station. The pressurized module was
00:06:50.000 --> 00:06:52.550
fabricated by Thaloselenia Space In
00:06:52.560 --> 00:06:54.230
Italy and then shipped to Northrop
00:06:54.240 --> 00:06:56.309
Grumman's facility in Gilbert, Arizona
00:06:56.319 --> 00:06:58.950
for final fit out. It'll then be sent to
00:06:58.960 --> 00:07:00.950
NASA's Kennedy Space Center in Florida
00:07:00.960 --> 00:07:02.629
where it'll be integrated with the space
00:07:02.639 --> 00:07:05.029
station's PPE or power and propulsion
00:07:05.039 --> 00:07:07.510
element. The two components will then be
00:07:07.520 --> 00:07:09.029
launched together into lunar orbit
00:07:09.039 --> 00:07:11.110
aboard the SpaceX Falcon Heavy rocket
00:07:11.120 --> 00:07:13.029
ahead of the Artemus 4 manned lunar
00:07:13.039 --> 00:07:15.029
mission. Gateway is important to the
00:07:15.039 --> 00:07:17.110
Artemis program because it'll provide a
00:07:17.120 --> 00:07:18.950
staging post for man missions to the
00:07:18.960 --> 00:07:20.870
lunar surface and eventually man
00:07:20.880 --> 00:07:23.430
missions going to Mars. Halo will
00:07:23.440 --> 00:07:25.350
operate as the command and control hub
00:07:25.360 --> 00:07:27.589
for gateway. It's equipped with multiple
00:07:27.599 --> 00:07:29.029
docking ports which will be used by
00:07:29.039 --> 00:07:31.110
spacecraft such as NASA's Orion as well
00:07:31.120 --> 00:07:33.790
as Luna landers and cargo and logistics
00:07:33.800 --> 00:07:35.990
vehicles. And it will provide data
00:07:36.000 --> 00:07:37.830
handling, energy storage, power
00:07:37.840 --> 00:07:39.830
distribution, thermal regulation, and
00:07:39.840 --> 00:07:41.830
communications and tracking capabilities
00:07:41.840 --> 00:07:44.390
for the space station. Halo will also
00:07:44.400 --> 00:07:46.230
include the telecommunications section
00:07:46.240 --> 00:07:48.550
of the European Space Ay's Sprite
00:07:48.560 --> 00:07:50.629
service module that'll be slated to
00:07:50.639 --> 00:07:53.110
launch in 2027 and will include a small
00:07:53.120 --> 00:07:55.189
windowed habitation section as well as
00:07:55.199 --> 00:07:57.189
more docking ports, an airlock and
00:07:57.199 --> 00:07:59.029
refueling infrastructure for the space
00:07:59.039 --> 00:08:01.830
station and for lunar landers. Another
00:08:01.840 --> 00:08:03.189
component called the International
00:08:03.199 --> 00:08:05.510
Habitation Module or IHAB is now being
00:08:05.520 --> 00:08:07.430
jointly built by the European Space
00:08:07.440 --> 00:08:09.110
Agency and the Japan Aerospace
00:08:09.120 --> 00:08:11.830
Exploration Agency JAXA. It'll also
00:08:11.840 --> 00:08:14.950
launch sometime next year. An IHAB will
00:08:14.960 --> 00:08:17.110
also include a new Canadian Space Agency
00:08:17.120 --> 00:08:19.830
built robotic arm. Other proposed
00:08:19.840 --> 00:08:21.909
segments include more logistics modules
00:08:21.919 --> 00:08:23.830
for supplies and storage and a
00:08:23.840 --> 00:08:25.909
purpose-built airlock module for extra
00:08:25.919 --> 00:08:27.670
vehicle activities outside the space
00:08:27.680 --> 00:08:29.350
station as well as additional docking
00:08:29.360 --> 00:08:32.070
ports for deep space transports. The
00:08:32.080 --> 00:08:33.670
current plan is to have astronauts
00:08:33.680 --> 00:08:35.829
occupy the 40 ton space station for up
00:08:35.839 --> 00:08:38.709
to 90 days at a time. Now although it's
00:08:38.719 --> 00:08:40.310
called a lunar space station, it's
00:08:40.320 --> 00:08:42.630
actually quite a bit away from the moon.
00:08:42.640 --> 00:08:44.470
Se gateway will be positioned in a
00:08:44.480 --> 00:08:46.550
highly elliptical trans lunar orbit
00:08:46.560 --> 00:08:48.470
known as a near rectal linear halo
00:08:48.480 --> 00:08:50.710
orbit. Instead of orbiting directly
00:08:50.720 --> 00:08:52.710
around the moon in low lunar orbit like
00:08:52.720 --> 00:08:54.150
the International Space Station does
00:08:54.160 --> 00:08:56.070
around the Earth, Gateway will follow a
00:08:56.080 --> 00:08:59.030
highly eccentric path. At its closest,
00:08:59.040 --> 00:09:01.350
it'll pass about 3,000 km above the
00:09:01.360 --> 00:09:03.670
lunar surface, but its orbit will then
00:09:03.680 --> 00:09:06.470
swing it out to some 70,000 km away at
00:09:06.480 --> 00:09:08.949
its most distant orbital position. Now,
00:09:08.959 --> 00:09:11.190
this design will allow Gayway to be both
00:09:11.200 --> 00:09:12.710
relatively close to the moon for
00:09:12.720 --> 00:09:14.389
excursions down to the lunar surface,
00:09:14.399 --> 00:09:16.310
but also allow for shorter trips to the
00:09:16.320 --> 00:09:18.230
space station by spacecraft traveling to
00:09:18.240 --> 00:09:19.949
and from the Earth with crew and
00:09:19.959 --> 00:09:22.470
supplies. See, most current rockets
00:09:22.480 --> 00:09:24.310
don't have the power to reach the moon
00:09:24.320 --> 00:09:26.310
directly in one go, but they could reach
00:09:26.320 --> 00:09:28.870
Gateway. So after liftoff only a
00:09:28.880 --> 00:09:30.949
moderate maneuver will be needed to slow
00:09:30.959 --> 00:09:33.230
a visiting spacecraft for rendevu with
00:09:33.240 --> 00:09:35.430
gateway for example it means Europe's
00:09:35.440 --> 00:09:37.910
Aran 6 could be used to deliver supplies
00:09:37.920 --> 00:09:39.750
for astronauts for use on missions to
00:09:39.760 --> 00:09:42.470
the moon or deeper into space and at the
00:09:42.480 --> 00:09:44.070
other end of the journey NASA will be
00:09:44.080 --> 00:09:46.230
using a modified version of SpaceX's
00:09:46.240 --> 00:09:48.150
Starship known as the SpaceX human
00:09:48.160 --> 00:09:51.350
landing system or hls as lunar shuttle
00:09:51.360 --> 00:09:53.509
transporting crews robot supplies and
00:09:53.519 --> 00:09:55.430
infrastructure from gateway down to the
00:09:55.440 --> 00:09:57.430
lunar surface when the space stations
00:09:57.440 --> 00:09:59.269
closest to the moon and that will happen
00:09:59.279 --> 00:10:02.230
about once every 7 days. Likewise, a
00:10:02.240 --> 00:10:04.070
transfer window to gateway opens about
00:10:04.080 --> 00:10:06.150
every 7 days for the return trip from
00:10:06.160 --> 00:10:08.630
the lunar surface to the space station.
00:10:08.640 --> 00:10:10.710
And gateways orbit will rotate together
00:10:10.720 --> 00:10:13.269
with the moon. As seen from Earth, it'll
00:10:13.279 --> 00:10:15.590
appear a little bit like a lunar halo.
00:10:15.600 --> 00:10:17.269
Now, orbits like this are possible
00:10:17.279 --> 00:10:18.870
because of the interplay between the
00:10:18.880 --> 00:10:20.310
Earth and the Moon's gravitational
00:10:20.320 --> 00:10:23.110
forces. As the two large bodies dance
00:10:23.120 --> 00:10:25.190
through space, a smaller object can be
00:10:25.200 --> 00:10:26.790
caught in a variety of stable and
00:10:26.800 --> 00:10:28.790
nearstable positions in relation to the
00:10:28.800 --> 00:10:31.030
orbiting masses, also known as libration
00:10:31.040 --> 00:10:34.150
or lrangeian points. Such locations are
00:10:34.160 --> 00:10:35.910
perfect for planning long-term missions,
00:10:35.920 --> 00:10:37.750
and to some extent, they'll dictate the
00:10:37.760 --> 00:10:39.430
design of the spacecraft, what it can
00:10:39.440 --> 00:10:41.509
carry to and from orbit, how much energy
00:10:41.519 --> 00:10:43.829
it needs to get and stay there.
00:10:43.839 --> 00:10:45.750
traveling on the near rectal linear halo
00:10:45.760 --> 00:10:47.829
orbit. One revolution of gateway in its
00:10:47.839 --> 00:10:49.590
orbit around the moon will take seven
00:10:49.600 --> 00:10:52.150
Earth days. This period was chosen to
00:10:52.160 --> 00:10:53.670
limit the number of eclipses when
00:10:53.680 --> 00:10:55.509
gateway would be shrouded by the earth
00:10:55.519 --> 00:10:57.990
or moon shadow. However, near rectal
00:10:58.000 --> 00:11:00.470
linear halo orbits are slightly unstable
00:11:00.480 --> 00:11:02.389
and objects in these orbits do have a
00:11:02.399 --> 00:11:04.870
tendency of drifting away. That means
00:11:04.880 --> 00:11:06.790
regular small station keeping maneuvers
00:11:06.800 --> 00:11:08.470
will be needed to keep gateway in
00:11:08.480 --> 00:11:10.550
position. We've learned how to do that
00:11:10.560 --> 00:11:12.069
by keeping the International Space
00:11:12.079 --> 00:11:13.750
Station in its correct orbital height
00:11:13.760 --> 00:11:16.069
above the Earth. This report on the
00:11:16.079 --> 00:11:18.740
Gateway project by NASA
00:11:18.750 --> 00:11:21.870
[Music]
00:11:21.880 --> 00:11:24.870
TV. Gateway is in and of itself a
00:11:24.880 --> 00:11:27.670
humongous technological marvel. It is
00:11:27.680 --> 00:11:30.470
the first space station around the moon.
00:11:30.480 --> 00:11:32.710
It is going to be a very important part
00:11:32.720 --> 00:11:36.069
of our future exploration missions. We
00:11:36.079 --> 00:11:38.550
know how to live and work in low Earth
00:11:38.560 --> 00:11:41.030
orbit, but now it's time to go further.
00:11:41.040 --> 00:11:42.710
Artemis is going to take us to parts of
00:11:42.720 --> 00:11:45.110
the moon that we haven't been to before.
00:11:45.120 --> 00:11:47.190
Going back to the moon has to be an
00:11:47.200 --> 00:11:49.430
international cooperation. The resources
00:11:49.440 --> 00:11:53.030
and the efforts required to make this
00:11:53.040 --> 00:11:55.110
happen are just too much for any single
00:11:55.120 --> 00:11:57.750
nation to to go on their own. There's
00:11:57.760 --> 00:11:59.990
the old saying that if you want to go
00:12:00.000 --> 00:12:02.870
fast, you go alone. If you want to go
00:12:02.880 --> 00:12:06.310
for a long time, you go together. And so
00:12:06.320 --> 00:12:08.949
it's going to take a humankind effort to
00:12:08.959 --> 00:12:11.030
go to the moon and then use that as a
00:12:11.040 --> 00:12:13.829
stepping stone to go to Mars. To be able
00:12:13.839 --> 00:12:16.310
to go and do lunar surface exploration
00:12:16.320 --> 00:12:18.069
missions and do sustainable missions, be
00:12:18.079 --> 00:12:19.750
able to do long duration missions, go to
00:12:19.760 --> 00:12:21.509
the moon to stay rather than just to
00:12:21.519 --> 00:12:23.910
visit like we did duro, we need a space
00:12:23.920 --> 00:12:26.710
station and gateways that station. The
00:12:26.720 --> 00:12:28.150
international crews and the
00:12:28.160 --> 00:12:29.910
international astronauts that'll perform
00:12:29.920 --> 00:12:32.310
these missions will be the first humans
00:12:32.320 --> 00:12:34.030
that are making their home in deep
00:12:34.040 --> 00:12:36.310
space. I think about all that we've
00:12:36.320 --> 00:12:37.829
learned from the International Space
00:12:37.839 --> 00:12:40.870
Station as a low Earth orbit laboratory.
00:12:40.880 --> 00:12:43.670
Gateway will be an extension of that and
00:12:43.680 --> 00:12:45.509
continue that legacy of science and
00:12:45.519 --> 00:12:47.910
discovery.
00:12:47.920 --> 00:12:50.069
We are going to be learning about deep
00:12:50.079 --> 00:12:52.470
space exploration. When we're in low
00:12:52.480 --> 00:12:54.269
Earth orbit, we're
00:12:54.279 --> 00:12:56.949
protected. When we are around the moon,
00:12:56.959 --> 00:12:59.190
we don't have that protection. So, it is
00:12:59.200 --> 00:13:00.110
going to
00:13:00.120 --> 00:13:01.710
affect
00:13:01.720 --> 00:13:04.470
everything. We have the very unique
00:13:04.480 --> 00:13:07.310
ability at Gateway to study that
00:13:07.320 --> 00:13:10.230
radiation. Gateway sounds so science
00:13:10.240 --> 00:13:12.150
fiction, but it's real and we're
00:13:12.160 --> 00:13:14.550
building it and science will never be
00:13:14.560 --> 00:13:16.710
the same. In one of the first steps of
00:13:16.720 --> 00:13:19.190
our Aremis lunar exploration plans, we
00:13:19.200 --> 00:13:21.590
have selected Maxar Technologies to
00:13:21.600 --> 00:13:23.910
provide the power and propulsion element
00:13:23.920 --> 00:13:26.710
for our lunar gateway. The power and
00:13:26.720 --> 00:13:28.949
propulsion element is a spacecraft that
00:13:28.959 --> 00:13:30.949
will use high-ower solar electric
00:13:30.959 --> 00:13:33.350
propulsion to give our explorers aboard
00:13:33.360 --> 00:13:35.750
the gateway access to the entire surface
00:13:35.760 --> 00:13:38.150
of the moon. It will also enable the
00:13:38.160 --> 00:13:40.389
gateway to serve as a mobile command and
00:13:40.399 --> 00:13:42.150
service module by providing a
00:13:42.160 --> 00:13:44.470
communications relay for human and
00:13:44.480 --> 00:13:46.550
robotic expeditions to the lunar
00:13:46.560 --> 00:13:49.350
surface. This is a critical capability
00:13:49.360 --> 00:13:52.310
for not just a sustainable lunar return,
00:13:52.320 --> 00:13:55.269
but also an eventual journey to Mars.
00:13:55.279 --> 00:13:57.670
NASA's current lunar exploration plans
00:13:57.680 --> 00:13:59.670
call for a return to the moon that
00:13:59.680 --> 00:14:01.670
sustained human presence on and around
00:14:01.680 --> 00:14:06.400
the moon by 2028.
00:14:06.410 --> 00:14:08.230
[Music]
00:14:08.240 --> 00:14:11.430
This is Spaceime. Still to come, more
00:14:11.440 --> 00:14:13.030
space junk threatens the International
00:14:13.040 --> 00:14:15.030
Space Station. And later in the science
00:14:15.040 --> 00:14:17.430
report, new insights into how the
00:14:17.440 --> 00:14:19.750
Earth's continents are moving. All that
00:14:19.760 --> 00:14:31.770
and more still to come on
00:14:31.780 --> 00:14:36.990
[Music]
00:14:37.000 --> 00:14:39.189
Spaceime. NASA has been forced to move
00:14:39.199 --> 00:14:41.110
the International Space Station again to
00:14:41.120 --> 00:14:42.949
avoid some large fragments of space
00:14:42.959 --> 00:14:45.030
junk. The orbital correction maneuver
00:14:45.040 --> 00:14:47.430
involved the Russian Progress MS30 cargo
00:14:47.440 --> 00:14:48.790
ship which was docked to the space
00:14:48.800 --> 00:14:51.069
station firing its thrusters for a
00:14:51.079 --> 00:14:53.670
212.79 second burn in the process
00:14:53.680 --> 00:14:55.110
increasing the station's orbital
00:14:55.120 --> 00:14:58.629
altitude by 540 m. Now without this
00:14:58.639 --> 00:15:00.470
maneuver NASA estimated the fragment
00:15:00.480 --> 00:15:02.310
could have come within 6 kilometers of
00:15:02.320 --> 00:15:04.389
the space station. That's too close for
00:15:04.399 --> 00:15:06.470
comfort. The space junk's been
00:15:06.480 --> 00:15:08.550
identified as part of a Chinese long mar
00:15:08.560 --> 00:15:11.509
rocket launched back in 2005.
00:15:11.519 --> 00:15:13.509
Space junk has become a constant problem
00:15:13.519 --> 00:15:15.350
for crew aboard the orbiting outpost
00:15:15.360 --> 00:15:17.110
with collision avoidance maneuvers now
00:15:17.120 --> 00:15:19.470
being undertaken multiple times every
00:15:19.480 --> 00:15:22.150
year. Each time it happens, crew have to
00:15:22.160 --> 00:15:23.910
stop where they're doing, take refuge
00:15:23.920 --> 00:15:26.310
inside one of the dock capsules just in
00:15:26.320 --> 00:15:28.150
case something hits the space station
00:15:28.160 --> 00:15:29.670
and they're forced to make an emergency
00:15:29.680 --> 00:15:32.550
evacuation and return to Earth. And the
00:15:32.560 --> 00:15:34.470
trouble is that problem is only going to
00:15:34.480 --> 00:15:37.500
get worse. This is
00:15:37.510 --> 00:15:48.020
[Music]
00:15:52.199 --> 00:15:54.470
spacetime. And time now to take another
00:15:54.480 --> 00:15:55.829
brief look at some of the other stories
00:15:55.839 --> 00:15:57.749
making news in science this week with a
00:15:57.759 --> 00:16:00.870
science report. A computer simulation of
00:16:00.880 --> 00:16:03.030
Earth's population growth has shown that
00:16:03.040 --> 00:16:04.790
humans will need to have more babies
00:16:04.800 --> 00:16:07.189
than the current rates if the species is
00:16:07.199 --> 00:16:09.749
meant to avoid extinction. The findings
00:16:09.759 --> 00:16:11.749
reported in the journal plus one shows
00:16:11.759 --> 00:16:14.230
that homo sapien survival requires every
00:16:14.240 --> 00:16:15.990
woman of childbearing age to have an
00:16:16.000 --> 00:16:18.629
average of at least 2.7 children, much
00:16:18.639 --> 00:16:20.870
higher than the 2.1 previously thought
00:16:20.880 --> 00:16:23.269
would be enough to keep people going.
00:16:23.279 --> 00:16:25.269
The researchers say the previous 2.1
00:16:25.279 --> 00:16:27.350
kids per woman rate doesn't account for
00:16:27.360 --> 00:16:29.030
random differences in how many kids
00:16:29.040 --> 00:16:31.269
people have or things like birth rates,
00:16:31.279 --> 00:16:33.110
gender ratios, and the fact that some
00:16:33.120 --> 00:16:35.670
people never have children at all. They
00:16:35.680 --> 00:16:37.350
say the research shows that women need
00:16:37.360 --> 00:16:40.069
to have at least 2.7 kids to reliably
00:16:40.079 --> 00:16:41.749
avoid eventual extinction of the
00:16:41.759 --> 00:16:44.069
species, especially in populations that
00:16:44.079 --> 00:16:47.269
are already small. So, it's one kid for
00:16:47.279 --> 00:16:51.749
mom, one for dad, and one for humanity.
00:16:51.759 --> 00:16:53.910
A new analysis of lava flows that
00:16:53.920 --> 00:16:55.829
solidified and broke apart over a
00:16:55.839 --> 00:16:57.350
massive crack in the earth's crust in
00:16:57.360 --> 00:16:59.509
Turkey has brought new insights into how
00:16:59.519 --> 00:17:02.069
continents move. The findings reported
00:17:02.079 --> 00:17:03.749
in the journal communications earthn
00:17:03.759 --> 00:17:05.750
environment will help improve science's
00:17:05.760 --> 00:17:08.150
understanding of earthquake risks. The
00:17:08.160 --> 00:17:10.150
new research by Curtain University has
00:17:10.160 --> 00:17:12.230
revealed that Sugaloo Fold zone, a more
00:17:12.240 --> 00:17:14.549
than 200 km long geological structure
00:17:14.559 --> 00:17:16.789
visible from space, is slowly pulling
00:17:16.799 --> 00:17:18.870
apart, providing a rare glimpse into the
00:17:18.880 --> 00:17:20.549
forces that shape Earth's crust when
00:17:20.559 --> 00:17:23.189
plates collide. The study solves a
00:17:23.199 --> 00:17:25.189
long-standing mystery about the fault's
00:17:25.199 --> 00:17:27.270
movement, unambiguously revealing that
00:17:27.280 --> 00:17:29.430
the fault is pulling apart at a rate of
00:17:29.440 --> 00:17:31.990
about 1 mm per year, rather than, as
00:17:32.000 --> 00:17:33.669
other studies have suggested, it's
00:17:33.679 --> 00:17:36.470
shifting sideways. Understanding these
00:17:36.480 --> 00:17:38.150
movements is crucial not just for
00:17:38.160 --> 00:17:39.590
assessing volcanic and earthquake
00:17:39.600 --> 00:17:41.510
threats, but also for improving global
00:17:41.520 --> 00:17:44.029
models of continental
00:17:44.039 --> 00:17:46.470
defamation. A new study has shown that
00:17:46.480 --> 00:17:48.470
teenagers diagnosed with a mental health
00:17:48.480 --> 00:17:50.390
condition report spending about 50
00:17:50.400 --> 00:17:52.789
minutes extra per day on social media
00:17:52.799 --> 00:17:55.350
compared to their peers. The findings
00:17:55.360 --> 00:17:56.950
reported in the journal Nature Human
00:17:56.960 --> 00:17:59.110
Behavior looked at self-reported social
00:17:59.120 --> 00:18:01.909
media use among more than 3,000 teens,
00:18:01.919 --> 00:18:04.150
16% of whom had at least one diagnosed
00:18:04.160 --> 00:18:06.310
mental health condition. The researchers
00:18:06.320 --> 00:18:08.070
say participants with depression or
00:18:08.080 --> 00:18:10.230
anxiety disorders, reported comparing
00:18:10.240 --> 00:18:12.150
themselves to others on social media
00:18:12.160 --> 00:18:14.390
more frequently. They also reported
00:18:14.400 --> 00:18:15.990
being less happy with the number of
00:18:16.000 --> 00:18:17.750
friends or followers they have on social
00:18:17.760 --> 00:18:19.510
media and that their mood was more
00:18:19.520 --> 00:18:21.590
strongly being impacted by how many
00:18:21.600 --> 00:18:24.590
likes, shares, and comments they
00:18:24.600 --> 00:18:26.870
get. Apple have started rolling out
00:18:26.880 --> 00:18:28.390
their latest series of updates for
00:18:28.400 --> 00:18:30.710
iPhones, tablets, and Macs. With the
00:18:30.720 --> 00:18:32.230
details, we're joined by technology
00:18:32.240 --> 00:18:35.430
editor Alex Haravo from techadvice.live.
00:18:35.440 --> 00:18:37.909
the ritual of updating all of our
00:18:37.919 --> 00:18:40.390
devices on seemingly a monthly basis is
00:18:40.400 --> 00:18:43.510
about to start up again with iOS 18.5.
00:18:43.520 --> 00:18:45.430
Currently, I'm running the release
00:18:45.440 --> 00:18:47.350
candidate, but by the time people are
00:18:47.360 --> 00:18:49.909
hearing this, iOS 18.5 should be out.
00:18:49.919 --> 00:18:52.070
And uh whilst there's the usual bug
00:18:52.080 --> 00:18:54.870
fixes and new wallpapers, there is
00:18:54.880 --> 00:18:56.549
sometimes some new features. And the
00:18:56.559 --> 00:18:58.230
feature that really caught my eye was
00:18:58.240 --> 00:19:00.870
that the emergency SOS and messaging
00:19:00.880 --> 00:19:03.029
features that were debuted with the
00:19:03.039 --> 00:19:05.430
iPhone 14 and then were available with
00:19:05.440 --> 00:19:07.750
the iPhone 15 and 16 are actually going
00:19:07.760 --> 00:19:10.789
to be backported to the iPhone 13. So
00:19:10.799 --> 00:19:12.310
this is big. I mean, they clearly had
00:19:12.320 --> 00:19:14.070
the technology ready to go at the time,
00:19:14.080 --> 00:19:16.150
but the satellites weren't in place or
00:19:16.160 --> 00:19:18.390
maybe they just weren't ready to launch
00:19:18.400 --> 00:19:20.070
it. This is going to be something that
00:19:20.080 --> 00:19:22.390
enables millions more people in the case
00:19:22.400 --> 00:19:25.430
of an emergency. I think satellites up
00:19:25.440 --> 00:19:26.789
there. I think that's the key. One of
00:19:26.799 --> 00:19:28.230
the flights had launched 29 more
00:19:28.240 --> 00:19:29.590
satellites. I mean, Elon is launching
00:19:29.600 --> 00:19:31.590
more and more satellites all the time.
00:19:31.600 --> 00:19:33.350
And uh he's also upgrading his
00:19:33.360 --> 00:19:35.830
satellites to version two, which can do
00:19:35.840 --> 00:19:38.470
higher bandwidth and will in the future
00:19:38.480 --> 00:19:40.950
enable voice and video calls as well as
00:19:40.960 --> 00:19:42.710
high-speed data. I mean, at the moment,
00:19:42.720 --> 00:19:44.549
most people are just using it to send
00:19:44.559 --> 00:19:46.390
messages for emergencies, but also if
00:19:46.400 --> 00:19:47.990
they're off the beaten track, they can
00:19:48.000 --> 00:19:50.789
send find my notifications to relatives
00:19:50.799 --> 00:19:53.029
who know that they can't otherwise track
00:19:53.039 --> 00:19:55.590
their loved ones on some hiking trail
00:19:55.600 --> 00:19:57.110
because there's no 4G or 5G
00:19:57.120 --> 00:19:59.190
infrastructure. So, yeah, the satellite
00:19:59.200 --> 00:20:01.669
revolution has really accelerated and by
00:20:01.679 --> 00:20:04.230
2030, being able to access voice and
00:20:04.240 --> 00:20:05.990
data from virtually anywhere on the
00:20:06.000 --> 00:20:07.510
planet, unless you're deep underground,
00:20:07.520 --> 00:20:09.510
is going to be just taken for granted.
00:20:09.520 --> 00:20:11.350
Just in the same way that we take mobile
00:20:11.360 --> 00:20:13.270
phones for granted today and yet in the
00:20:13.280 --> 00:20:15.990
80s it was car phones. So these updates
00:20:16.000 --> 00:20:17.510
will they be extended to other products
00:20:17.520 --> 00:20:20.150
as well? Yes, there'll be 18.5 for iPad
00:20:20.160 --> 00:20:23.029
OS, 15.5 for Mac OS, should be 11.5 for
00:20:23.039 --> 00:20:25.750
the watch OS and new versions 2.5 for
00:20:25.760 --> 00:20:27.909
the Vision Pro OS. So yeah, all the
00:20:27.919 --> 00:20:29.590
different Apple devices. If your device
00:20:29.600 --> 00:20:31.909
can still get updates, expect an update
00:20:31.919 --> 00:20:33.270
by the time you're hearing this. And if
00:20:33.280 --> 00:20:34.950
not, it'll be in in the very few days
00:20:34.960 --> 00:20:37.029
thereafter. But uh new updates coming
00:20:37.039 --> 00:20:39.110
all the time. Stay updated. That's Alex
