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
