SpaceTime with Stuart Gary Gary - Series 29 Episode 24

In this episode of SpaceTime , we uncover astonishing discoveries about the birth of black holes, a revolutionary Martian navigation system, and the arrival of NASA's SpaceX Crew 12 at the International Space Station.

The Birth of a Black Hole: A New Perspective

Astronomers have made a groundbreaking discovery by observing a star in the Andromeda Galaxy collapsing into a black hole without the expected supernova explosion. The star, catalogued as M31 2014 DS1, was seen glowing brightly in infrared light before fading away, leaving behind a dust shell. This event, which had been anticipated for decades, suggests that massive stars may collapse directly into black holes, challenging long-held assumptions about stellar deaths. The findings, published in the journal Science, provide new insights into the processes that govern black hole formation and indicate that such direct collapses may be more common than previously thought.

NASA's New Martian Navigation System

NASA has introduced an innovative navigation system for its Perseverance rover, allowing it to determine its location on Mars with remarkable precision—within 25 centimeters. The new technology, called Mars Global Localization, enables the rover to autonomously compare panoramic images with orbital terrain maps, eliminating the need for Earth-based assistance. This advancement significantly enhances the rover's ability to explore the Martian surface independently, paving the way for more extensive scientific investigations.

SpaceX Crew 12 Arrives at the ISS

NASA's SpaceX Crew 12 has successfully docked with the International Space Station, restoring the crew complement to seven members. The mission includes a diverse crew of two Americans, a Russian, and a French astronaut, who will conduct approximately 250 scientific experiments in orbit. Additionally, NASA has approved a sixth private mission to the ISS, slated for next year, which aims to support new research initiatives and infrastructure development for future human spaceflight missions.

00:00:00.160 --> 00:00:03.350
This is Spacetime Series 29, episode 24


00:00:03.360 --> 00:00:05.510
for broadcast on the 25th of February


00:00:05.520 --> 00:00:07.110
2026.


00:00:07.120 --> 00:00:10.070
Coming up on Spaceime, the clearest view


00:00:10.080 --> 00:00:13.030
yet of the birth of a black hole, a new


00:00:13.040 --> 00:00:15.270
Martian navigation system for use on the


00:00:15.280 --> 00:00:18.870
red planet, and NASA's SpaceX Crew 12


00:00:18.880 --> 00:00:20.630
arrives aboard the International Space


00:00:20.640 --> 00:00:23.029
Station as the agency approves a sixth


00:00:23.039 --> 00:00:25.830
private mission to the orbiting outpost.


00:00:25.840 --> 00:00:44.790
All that and more coming up on Spaceime.


00:00:44.800 --> 00:00:46.869
Astronomers have discovered a star


00:00:46.879 --> 00:00:48.709
collapsing down to form a black hole


00:00:48.719 --> 00:00:51.270
without the expected blinding blast of a


00:00:51.280 --> 00:00:55.029
supernova explosion. Back in 2014, a


00:00:55.039 --> 00:00:56.869
NASA telescope observed infrared


00:00:56.879 --> 00:00:58.950
emissions coming from a massive star in


00:00:58.960 --> 00:01:01.270
the Andromeda galaxy M31, which


00:01:01.280 --> 00:01:04.229
gradually grew brighter. The star glowed


00:01:04.239 --> 00:01:06.230
more intensely with infrared light for


00:01:06.240 --> 00:01:08.789
around 3 years before finally fading


00:01:08.799 --> 00:01:10.789
dramatically and disappearing, leaving


00:01:10.799 --> 00:01:14.230
behind a shell of dust. Now, astronomers


00:01:14.240 --> 00:01:16.070
have determined what they witnessed was


00:01:16.080 --> 00:01:18.870
a star collapsing and giving birth to a


00:01:18.880 --> 00:01:21.429
stellar mass black hole. The study's


00:01:21.439 --> 00:01:23.590
lead author Kishali D from Columbia


00:01:23.600 --> 00:01:25.830
University says this is an event


00:01:25.840 --> 00:01:28.230
astronomers had anticipated for decades


00:01:28.240 --> 00:01:29.670
but have had limited convincing


00:01:29.680 --> 00:01:32.630
observational evidence for until now.


00:01:32.640 --> 00:01:34.469
The findings reported in the journal


00:01:34.479 --> 00:01:37.030
Science show a star undergoing direct


00:01:37.040 --> 00:01:38.950
collapse turning into a black hole


00:01:38.960 --> 00:01:40.950
without first exploding and becoming a


00:01:40.960 --> 00:01:43.190
supernova. Long believed to be a common


00:01:43.200 --> 00:01:45.190
method for highmass stars to become


00:01:45.200 --> 00:01:48.230
black holes. The progenitor star was a


00:01:48.240 --> 00:01:50.469
huge hydrogen- depleted super giant


00:01:50.479 --> 00:01:54.789
named M31 2014 DS1 located some 2 and a


00:01:54.799 --> 00:01:57.030
half million lighty years away. When


00:01:57.040 --> 00:01:59.749
newly formed, this star was around 13


00:01:59.759 --> 00:02:02.149
times the mass of our sun. But at the


00:02:02.159 --> 00:02:03.429
time of its death, it would have been


00:02:03.439 --> 00:02:05.670
closer to five solar masses, having shed


00:02:05.680 --> 00:02:07.190
most of its mass through powerful


00:02:07.200 --> 00:02:10.309
stellar winds during its life. D says


00:02:10.319 --> 00:02:12.390
the dramatic and sustained fading of the


00:02:12.400 --> 00:02:15.110
star was very unusual and suggests a


00:02:15.120 --> 00:02:17.750
supernova failed to occur leading to the


00:02:17.760 --> 00:02:19.910
collapse of the stars c directly into a


00:02:19.920 --> 00:02:22.470
black hole. Now stars with this sort of


00:02:22.480 --> 00:02:24.630
mass have long been assumed to always


00:02:24.640 --> 00:02:27.350
explode a supernova. The fact that it


00:02:27.360 --> 00:02:29.430
didn't suggests that stars with this


00:02:29.440 --> 00:02:31.430
sort of mass range may or may not


00:02:31.440 --> 00:02:33.830
successfully explode. possibly due to


00:02:33.840 --> 00:02:35.910
how gravity, gas pressure, and powerful


00:02:35.920 --> 00:02:37.910
shock waves interact in chaotic ways


00:02:37.920 --> 00:02:40.630
with each other inside the dying star.


00:02:40.640 --> 00:02:42.550
The manner in which the star turned into


00:02:42.560 --> 00:02:44.710
a black hole suggest that at the end of


00:02:44.720 --> 00:02:47.030
its life, its inner core wasn't pushed


00:02:47.040 --> 00:02:49.589
out in a normal supernova explosion,


00:02:49.599 --> 00:02:52.150
instead undergoing a complete inward


00:02:52.160 --> 00:02:53.830
collapse.


00:02:53.840 --> 00:02:56.229
Now, this process of direct collapse to


00:02:56.239 --> 00:02:57.990
form a black hole may have been seen at


00:02:58.000 --> 00:03:01.110
least once before. It was back in 2010


00:03:01.120 --> 00:03:04.309
in the galaxy NGC6946,


00:03:04.319 --> 00:03:06.149
which is about 10 times further away


00:03:06.159 --> 00:03:08.790
than this star. But the exact nature of


00:03:08.800 --> 00:03:11.030
that event was unclear and hotly debated


00:03:11.040 --> 00:03:13.030
in astronomical circles because it was


00:03:13.040 --> 00:03:14.869
100 times fainter and there wasn't


00:03:14.879 --> 00:03:16.949
enough highquality data available about


00:03:16.959 --> 00:03:19.670
it. Now, astronomers have long known


00:03:19.680 --> 00:03:22.070
that stellar mass black holes are caused


00:03:22.080 --> 00:03:24.710
by the death of massive stars. Black


00:03:24.720 --> 00:03:26.550
holes were first theorized more than 50


00:03:26.560 --> 00:03:28.630
years ago, and today we know of dozens


00:03:28.640 --> 00:03:30.949
in our own galaxy and hundreds of others


00:03:30.959 --> 00:03:32.630
detected from gravitational wave


00:03:32.640 --> 00:03:34.470
observations across the distant


00:03:34.480 --> 00:03:37.190
universe. However, scientists still have


00:03:37.200 --> 00:03:39.750
no clear consensus on which stars turned


00:03:39.760 --> 00:03:41.830
into black holes and how that process


00:03:41.840 --> 00:03:44.470
plays out. This discovery provides the


00:03:44.480 --> 00:03:46.229
clearest insights yet into this and


00:03:46.239 --> 00:03:47.910
indicates that this kind of stellar


00:03:47.920 --> 00:03:49.910
collapse may happen more often than


00:03:49.920 --> 00:03:52.309
scientists had previously thought. The


00:03:52.319 --> 00:03:54.470
authors discovered the star by analyzing


00:03:54.480 --> 00:03:56.789
archival data from NASA's Neoise


00:03:56.799 --> 00:03:59.110
mission. They used a prediction from the


00:03:59.120 --> 00:04:01.830
1970s that theorized that when a star


00:04:01.840 --> 00:04:03.670
underwent direct collapse, it would


00:04:03.680 --> 00:04:06.309
leave behind a faint infrared glow


00:04:06.319 --> 00:04:08.470
caused by the dying gasp of the star


00:04:08.480 --> 00:04:10.470
shedding its outer layers and becoming


00:04:10.480 --> 00:04:13.110
enshrouded in dust. So they conducted


00:04:13.120 --> 00:04:15.270
the largest study of variable infrared


00:04:15.280 --> 00:04:17.590
sources ever carried out, tracking every


00:04:17.600 --> 00:04:19.430
star in the Milky Way and other local


00:04:19.440 --> 00:04:21.670
galaxies to try and search out for these


00:04:21.680 --> 00:04:24.230
events and eventually they came across


00:04:24.240 --> 00:04:28.629
M31 2014 DS1. Further analysis showed


00:04:28.639 --> 00:04:30.550
that this star fitted their predictions


00:04:30.560 --> 00:04:33.030
perfectly. D says, "Unlike finding a


00:04:33.040 --> 00:04:34.790
supernova, which is easy because


00:04:34.800 --> 00:04:36.870
supernova outshine the galaxies they're


00:04:36.880 --> 00:04:38.629
in for weeks at a time, finding


00:04:38.639 --> 00:04:40.950
individual stars that disappear without


00:04:40.960 --> 00:04:42.950
producing an explosion is incredibly


00:04:42.960 --> 00:04:45.990
difficult. So, it comes as a shock that


00:04:46.000 --> 00:04:48.230
a massive star basically disappeared


00:04:48.240 --> 00:04:50.390
without an explosion and nobody noticed


00:04:50.400 --> 00:04:53.110
it for more than 5 years. It impacts


00:04:53.120 --> 00:04:55.350
science's entire understanding of the


00:04:55.360 --> 00:04:57.670
inventory of massive stellar deaths in


00:04:57.680 --> 00:05:00.070
the universe. And it says there are


00:05:00.080 --> 00:05:02.070
things that may be quietly happening out


00:05:02.080 --> 00:05:05.430
there that are easily going unnoticed.


00:05:05.440 --> 00:05:07.670
This is spaceime.


00:05:07.680 --> 00:05:10.390
Still to come, NASA trails a new Martian


00:05:10.400 --> 00:05:12.790
navigation system on the red planet. And


00:05:12.800 --> 00:05:14.550
a new crew arrives aboard the


00:05:14.560 --> 00:05:16.870
International Space Station as NASA


00:05:16.880 --> 00:05:19.670
approves a sixth private mission to the


00:05:19.680 --> 00:05:21.909
orbiting outpost. All that and more


00:05:21.919 --> 00:05:29.430
still to come on Spaceime.

developed a new Martian navigation


00:06:43.360 --> 00:06:45.430
system, allowing its Mars Perseverance


00:06:45.440 --> 00:06:47.830
rover to pinpoint its location to within


00:06:47.840 --> 00:06:50.150
25 cm.


00:06:50.160 --> 00:06:52.309
Imagine you're all alone, driving along


00:06:52.319 --> 00:06:54.469
a rocky, unforgiving desert with no


00:06:54.479 --> 00:06:57.670
roads, no map, no GPS, and nothing more


00:06:57.680 --> 00:06:59.909
than a single phone call once a day for


00:06:59.919 --> 00:07:01.990
someone far away telling you where you


00:07:02.000 --> 00:07:05.029
are. Well, that's what the car size six


00:07:05.039 --> 00:07:06.550
wheel Perseverance rover has been


00:07:06.560 --> 00:07:08.550
experiencing ever since landing on the


00:07:08.560 --> 00:07:10.870
red planet almost exactly 5 years ago


00:07:10.880 --> 00:07:13.510
this month. Although it carries time-t


00:07:13.520 --> 00:07:15.589
tested tools for determining its general


00:07:15.599 --> 00:07:17.350
location, the rover has always needed


00:07:17.360 --> 00:07:19.270
mission managers back on Earth to tell


00:07:19.280 --> 00:07:22.230
it precisely where it is until now. A


00:07:22.240 --> 00:07:24.070
new technology developed by NASA's Jet


00:07:24.080 --> 00:07:25.909
Propulsion Laboratory in Pasadena,


00:07:25.919 --> 00:07:27.990
California will now allow Perseverance


00:07:28.000 --> 00:07:29.830
to figure out its whereabouts without


00:07:29.840 --> 00:07:32.230
needing to phone home for help. called


00:07:32.240 --> 00:07:34.950
Mars Global Localization. The technology


00:07:34.960 --> 00:07:36.870
features an algorithm that rapidly


00:07:36.880 --> 00:07:38.870
compares panoramic images from the


00:07:38.880 --> 00:07:41.270
rover's navigation cameras with onboard


00:07:41.280 --> 00:07:43.749
orbital terrain maps. Running on a


00:07:43.759 --> 00:07:45.589
powerful processor that Perseverance


00:07:45.599 --> 00:07:47.430
originally used to communicate with the


00:07:47.440 --> 00:07:49.830
Ingenuity Mars helicopter. The algorithm


00:07:49.840 --> 00:07:51.749
takes about 2 minutes to pinpoint the


00:07:51.759 --> 00:07:55.430
rover's location within 25 cm.


00:07:55.440 --> 00:07:57.430
Mission managers first used the Mars


00:07:57.440 --> 00:07:59.510
Global Localization Technology in


00:07:59.520 --> 00:08:01.270
successful mission operations on


00:08:01.280 --> 00:08:03.510
February the 2nd, then again on February


00:08:03.520 --> 00:08:06.710
the 16th. JPL's chief engineer of


00:08:06.720 --> 00:08:08.950
robotics operations, Vandy Vuma, says


00:08:08.960 --> 00:08:12.150
it's kind of like giving the rover GPS.


00:08:12.160 --> 00:08:13.749
It means Perseverance will be able to


00:08:13.759 --> 00:08:15.270
drive for much longer distances


00:08:15.280 --> 00:08:17.270
autonomously, thereby allowing more of


00:08:17.280 --> 00:08:18.869
the planet to be explored and more


00:08:18.879 --> 00:08:21.189
science to be gathered. The upgrades


00:08:21.199 --> 00:08:23.029
especially valuable given how well


00:08:23.039 --> 00:08:24.950
Perseverance's auto navigation


00:08:24.960 --> 00:08:27.510
self-driving systems been working.


00:08:27.520 --> 00:08:30.150
AutoNav enables the rover to replan its


00:08:30.160 --> 00:08:32.310
path around obstacles along its way in


00:08:32.320 --> 00:08:33.829
order to reach its pre-established


00:08:33.839 --> 00:08:36.310
destination. It's already proven so


00:08:36.320 --> 00:08:38.070
capable that the distance Perseverance


00:08:38.080 --> 00:08:39.750
can drive without instructions from


00:08:39.760 --> 00:08:42.070
Earth is largely now only limited by the


00:08:42.080 --> 00:08:43.909
rover's uncertainty about its exact


00:08:43.919 --> 00:08:46.550
location. The implementation of Mars


00:08:46.560 --> 00:08:48.710
global localization comes on the heels


00:08:48.720 --> 00:08:50.710
of another innovation from Perseverance


00:08:50.720 --> 00:08:52.790
mission managers. That is the first use


00:08:52.800 --> 00:08:55.110
of generative artificial intelligence to


00:08:55.120 --> 00:08:57.269
help plan a drive route by selecting way


00:08:57.279 --> 00:08:58.790
points for the rover which are normally


00:08:58.800 --> 00:09:01.829
chosen by human rover operators. Unlike


00:09:01.839 --> 00:09:04.389
on Earth, there are no GPS satellites in


00:09:04.399 --> 00:09:06.550
deep space to locate spacecraft on


00:09:06.560 --> 00:09:09.509
planetary surfaces. So missions whether


00:09:09.519 --> 00:09:11.269
robotic or manned need to come up with


00:09:11.279 --> 00:09:13.670
other ways to determine their location.


00:09:13.680 --> 00:09:15.430
Now, as with NASA's previous Mars


00:09:15.440 --> 00:09:17.590
rovers, Perseverance tracks its position


00:09:17.600 --> 00:09:19.750
using what's called visual odometry,


00:09:19.760 --> 00:09:21.670
analyzing geological features in camera


00:09:21.680 --> 00:09:23.750
images taken every few meters while


00:09:23.760 --> 00:09:26.470
accounting for wheel slippage. But as


00:09:26.480 --> 00:09:28.870
tiny errors in this process add up over


00:09:28.880 --> 00:09:30.630
the course of each drive, the rover


00:09:30.640 --> 00:09:32.470
becomes increasingly unsure about its


00:09:32.480 --> 00:09:35.110
exact location. Now, on long drives,


00:09:35.120 --> 00:09:36.710
that means the rover's sense of its


00:09:36.720 --> 00:09:39.670
position could be up by as much as 35 m.


00:09:39.680 --> 00:09:41.350
believing it may be too close to


00:09:41.360 --> 00:09:43.269
hazardous terrain, Perseverance then


00:09:43.279 --> 00:09:45.590
prematurely may end its drive and wait


00:09:45.600 --> 00:09:48.310
for fresh instructions from Earth. Verma


00:09:48.320 --> 00:09:50.310
says under those circumstances, people


00:09:50.320 --> 00:09:52.070
have to tell it, "You're not lost.


00:09:52.080 --> 00:09:54.550
You're safe. Keep going." Scientists


00:09:54.560 --> 00:09:55.990
knew that if they could address this


00:09:56.000 --> 00:09:57.670
problem, the rover could travel much


00:09:57.680 --> 00:10:00.389
further every day. After each drive


00:10:00.399 --> 00:10:03.190
comes to a halt, the rover sends a 360°


00:10:03.200 --> 00:10:05.509
panorama to Earth, where mapping experts


00:10:05.519 --> 00:10:07.350
match the imagery with shots of the


00:10:07.360 --> 00:10:09.509
Martian surface taken by NASA's Mars


00:10:09.519 --> 00:10:11.750
Reconnaissance Orbiter spacecraft.


00:10:11.760 --> 00:10:13.910
Mission managers then send the rover its


00:10:13.920 --> 00:10:15.990
location and instructions what to do


00:10:16.000 --> 00:10:18.710
next. Now, that process can take a day


00:10:18.720 --> 00:10:20.870
or more, but with the new Mars global


00:10:20.880 --> 00:10:22.790
localization technology, the rover is


00:10:22.800 --> 00:10:24.870
now able to compare images itself,


00:10:24.880 --> 00:10:27.030
determine its exact location, and roll


00:10:27.040 --> 00:10:30.150
ahead on its pre-planned route.


00:10:30.160 --> 00:10:32.630
Key to Mars global localization is the


00:10:32.640 --> 00:10:34.790
rover's helicopter base station, which


00:10:34.800 --> 00:10:36.630
Perseverance used to communicate with


00:10:36.640 --> 00:10:38.630
the now retired Ingenuity Mars


00:10:38.640 --> 00:10:40.630
helicopter. Equipped with an


00:10:40.640 --> 00:10:42.710
off-the-shelf commercial processor of


00:10:42.720 --> 00:10:44.710
the type fitted to mid2010 era


00:10:44.720 --> 00:10:46.870
smartphones, the technology can run over


00:10:46.880 --> 00:10:48.790
100 times faster than the robot's two


00:10:48.800 --> 00:10:50.550
main computers, which was specially


00:10:50.560 --> 00:10:52.550
developed to survive the radiationheavy


00:10:52.560 --> 00:10:54.310
Martian environment and are based on


00:10:54.320 --> 00:10:57.509
hardware introduced back in 1997.


00:10:57.519 --> 00:10:59.509
As a technology demonstration designed


00:10:59.519 --> 00:11:01.590
to test capabilities, the Ingenuity


00:11:01.600 --> 00:11:03.590
mission was able to risk employing more


00:11:03.600 --> 00:11:04.949
powerful commercial chips in the


00:11:04.959 --> 00:11:06.710
helicopter base station and on the


00:11:06.720 --> 00:11:08.550
rotocopter itself, even though they


00:11:08.560 --> 00:11:09.990
hadn't been proven in the space


00:11:10.000 --> 00:11:12.150
environment. It was a gamble, but it


00:11:12.160 --> 00:11:15.030
paid off with Ingenuity undertaking 72


00:11:15.040 --> 00:11:16.710
flights compared to the five test


00:11:16.720 --> 00:11:18.310
flights it was originally planned to


00:11:18.320 --> 00:11:20.790
undertake. Now, apart from the Mars


00:11:20.800 --> 00:11:22.790
Perseverance rover, this new technology


00:11:22.800 --> 00:11:24.630
could also find its way onto the moon,


00:11:24.640 --> 00:11:26.710
where lighting conditions and long, cold


00:11:26.720 --> 00:11:29.030
lunar nights make knowing exactly where


00:11:29.040 --> 00:11:31.269
a spacecraft's located all the more


00:11:31.279 --> 00:11:34.949
crucial. This report from NASA TV.


00:11:34.959 --> 00:11:37.190
>> Using a new technology called Mars


00:11:37.200 --> 00:11:39.750
Global Localization, the rover can now


00:11:39.760 --> 00:11:41.910
pinpoint its location without asking


00:11:41.920 --> 00:11:44.630
humans for help. Here's how it works.


00:11:44.640 --> 00:11:47.110
Perseverance takes panoramic images and


00:11:47.120 --> 00:11:49.910
turns it into a bird's eye view. Then an


00:11:49.920 --> 00:11:52.389
onboard algorithm rapidly compares those


00:11:52.399 --> 00:11:54.630
images to terrain maps from an orbiting


00:11:54.640 --> 00:11:56.870
spacecraft and determines the rover's


00:11:56.880 --> 00:11:59.590
precise location. The key to this quick


00:11:59.600 --> 00:12:01.829
computing is a processor Perseverance


00:12:01.839 --> 00:12:03.670
originally used to communicate with the


00:12:03.680 --> 00:12:06.870
Ingenuity Mars helicopter. Now it's


00:12:06.880 --> 00:12:08.629
helping Perseverance keep moving


00:12:08.639 --> 00:12:10.790
confidently. And global localization


00:12:10.800 --> 00:12:13.030
isn't the only recent innovation. The


00:12:13.040 --> 00:12:15.350
team has started to use generative AI to


00:12:15.360 --> 00:12:17.430
help plan the rover's driving path by


00:12:17.440 --> 00:12:19.350
creating way points for Mars. By


00:12:19.360 --> 00:12:21.430
leveraging decades of Mars knowledge and


00:12:21.440 --> 00:12:23.350
the latest advancements in technology,


00:12:23.360 --> 00:12:25.269
the rover will be able to drive for much


00:12:25.279 --> 00:12:27.509
longer distances autonomously. So, we'll


00:12:27.519 --> 00:12:29.750
explore more of the planet and get more


00:12:29.760 --> 00:12:30.550
science.


00:12:30.560 --> 00:12:33.509
>> This is space time. Still to come,


00:12:33.519 --> 00:12:36.069
NASA's SpaceX Crew 12 arrives aboard the


00:12:36.079 --> 00:12:37.670
International Space Station as the


00:12:37.680 --> 00:12:39.910
agency approves a new private mission,


00:12:39.920 --> 00:12:42.310
the sixth, to the orbiting outpost. And


00:12:42.320 --> 00:12:44.790
later in the science report, a new study


00:12:44.800 --> 00:12:47.110
warns that over fishing may be one of


00:12:47.120 --> 00:12:49.269
the key reasons for reef munching crown


00:12:49.279 --> 00:12:51.350
of thorn starfish outbreaks on the Great


00:12:51.360 --> 00:12:53.829
Barrier Reef. All that and more still to


00:12:53.839 --> 00:13:11.030
come on Spaceime.


00:13:11.040 --> 00:13:13.750
NASA's SpaceX Crew 12 Dragon capsule is


00:13:13.760 --> 00:13:14.790
successfully docked with the


00:13:14.800 --> 00:13:16.550
International Space Station, returning


00:13:16.560 --> 00:13:18.550
the orbiting outpost compliment back up


00:13:18.560 --> 00:13:21.509
to its usual seven crew members. The


00:13:21.519 --> 00:13:23.670
crew of two Americans, a Russian and a


00:13:23.680 --> 00:13:25.430
Frenchman, blasted off a day earlier


00:13:25.440 --> 00:13:27.590
aboard a Falcon 9 rocket from Space


00:13:27.600 --> 00:13:29.750
Launch Complex 40 at the Cape Canaveral


00:13:29.760 --> 00:13:32.389
Space Force Base in Florida. The Dragon


00:13:32.399 --> 00:13:34.470
spacecraft freedom, docked autonomously


00:13:34.480 --> 00:13:36.629
with the space-facing zenith port of the


00:13:36.639 --> 00:13:39.509
station's Harmony module. Crew 12 will


00:13:39.519 --> 00:13:42.470
now form part of the expedition 7475


00:13:42.480 --> 00:13:45.190
crew undertaking some 250 scientific


00:13:45.200 --> 00:13:47.590
experiments in orbit. These will include


00:13:47.600 --> 00:13:49.829
studying pneumonia causing bacteria to


00:13:49.839 --> 00:13:51.910
improve cardiovascular treatments, on


00:13:51.920 --> 00:13:54.230
demand intravenous fluid generation for


00:13:54.240 --> 00:13:56.470
future space missions, and research into


00:13:56.480 --> 00:13:58.550
how physical characteristics may affect


00:13:58.560 --> 00:14:00.870
blood flow during long duration space


00:14:00.880 --> 00:14:02.870
flight. Other experiments include


00:14:02.880 --> 00:14:04.949
automated plant health monitoring and


00:14:04.959 --> 00:14:07.110
investigating plant and nitrogen fixing


00:14:07.120 --> 00:14:09.110
microbe interactions to enhance food


00:14:09.120 --> 00:14:11.509
production in space. The International


00:14:11.519 --> 00:14:13.350
Space Station's been under man for about


00:14:13.360 --> 00:14:15.110
a month following the early return to


00:14:15.120 --> 00:14:17.509
Earth of NASA's SpaceX Crew 11 mission


00:14:17.519 --> 00:14:19.670
due to a medical emergency involving one


00:14:19.680 --> 00:14:21.670
of the astronauts.


00:14:21.680 --> 00:14:23.670
Meanwhile, NASA's just approved a new


00:14:23.680 --> 00:14:25.269
private astronaut mission to the


00:14:25.279 --> 00:14:27.269
International Space Station slated for


00:14:27.279 --> 00:14:30.230
later next year. The 14-day mission for


00:14:30.240 --> 00:14:32.550
the company Vast will undertake research


00:14:32.560 --> 00:14:34.550
designed to gain new insights into the


00:14:34.560 --> 00:14:36.629
infrastructure and processes that'll be


00:14:36.639 --> 00:14:38.550
needed to support Vast's own human


00:14:38.560 --> 00:14:40.310
spaceflight missions, which include


00:14:40.320 --> 00:14:41.990
building their own space station in low


00:14:42.000 --> 00:14:45.110
Earth orbit called Haven in 2027.


00:14:45.120 --> 00:14:46.870
Plans suggest Haven will be about the


00:14:46.880 --> 00:14:48.949
size of a truck with additional modules


00:14:48.959 --> 00:14:51.030
added in future years with the outpost


00:14:51.040 --> 00:14:53.910
becoming permanently manned by 2030.


00:14:53.920 --> 00:14:56.069
Vest's looking at research proposals on


00:14:56.079 --> 00:14:58.230
biology, biotechnology, physical


00:14:58.240 --> 00:15:00.470
sciences, human research, and technology


00:15:00.480 --> 00:15:03.430
demonstrations. Vast used SpaceX to


00:15:03.440 --> 00:15:05.590
launch the small haven demo spacecraft


00:15:05.600 --> 00:15:08.550
into orbit last year. The other big


00:15:08.560 --> 00:15:10.069
private company that's been flying


00:15:10.079 --> 00:15:11.350
people into space and to the


00:15:11.360 --> 00:15:13.509
International Space Station is Axiom,


00:15:13.519 --> 00:15:15.189
which has undertaken four missions to


00:15:15.199 --> 00:15:17.269
the orbiting outpost. As well as


00:15:17.279 --> 00:15:19.430
developing NASA's Arteimus space suits,


00:15:19.440 --> 00:15:21.350
Axiom Space is also developing their own


00:15:21.360 --> 00:15:23.829
commercial space station. Its initial


00:15:23.839 --> 00:15:25.509
modules will be attached to the existing


00:15:25.519 --> 00:15:27.269
international space station before


00:15:27.279 --> 00:15:29.030
becoming an independent free-flying


00:15:29.040 --> 00:15:30.870
platform when the international space


00:15:30.880 --> 00:15:34.230
stations retire in 2030. Axiom plan to


00:15:34.240 --> 00:15:35.910
use their space station to undertake


00:15:35.920 --> 00:15:37.750
microgravity research, various


00:15:37.760 --> 00:15:41.110
commercial endeavors, and space tourism.


00:15:41.120 --> 00:15:58.310
This is spaceime.


00:15:58.320 --> 00:16:00.150
And time out to take another brief look


00:16:00.160 --> 00:16:01.670
at some of the other stories making news


00:16:01.680 --> 00:16:03.509
in science this week with a science


00:16:03.519 --> 00:16:06.230
report. A new study warns that people


00:16:06.240 --> 00:16:08.150
are exposed to more air pollution are


00:16:08.160 --> 00:16:10.230
also far more likely to face a higher


00:16:10.240 --> 00:16:12.710
risk of developing Alzheimer's disease.


00:16:12.720 --> 00:16:14.310
The findings reported in the journal


00:16:14.320 --> 00:16:16.230
Plus Medicine looked at how much air


00:16:16.240 --> 00:16:19.269
pollution some 27.8 million people aged


00:16:19.279 --> 00:16:21.749
65 and over were exposed to over an


00:16:21.759 --> 00:16:24.389
18-year period. They found that people


00:16:24.399 --> 00:16:25.829
who had a greater exposure to air


00:16:25.839 --> 00:16:27.829
pollution were also far more likely to


00:16:27.839 --> 00:16:29.509
develop Alzheimer's than those who


00:16:29.519 --> 00:16:31.910
avoided air pollution. And the authors


00:16:31.920 --> 00:16:33.910
found the link was also stronger for


00:16:33.920 --> 00:16:36.069
people who had experienced a stroke.


00:16:36.079 --> 00:16:37.990
However, they found no additional effect


00:16:38.000 --> 00:16:40.230
in people with high blood pressure or


00:16:40.240 --> 00:16:42.710
with depression.


00:16:42.720 --> 00:16:44.710
Marine biologists are warning that over


00:16:44.720 --> 00:16:46.949
fishing may be the primary cause of reef


00:16:46.959 --> 00:16:49.670
munching crownthorn starfish outbreaks.


00:16:49.680 --> 00:16:51.269
The findings reported in the journal


00:16:51.279 --> 00:16:53.509
current biology found a reduction in the


00:16:53.519 --> 00:16:55.350
number of predatory fish due to over


00:16:55.360 --> 00:16:57.350
fishing is causing a population


00:16:57.360 --> 00:16:59.910
explosion in the carnivorous starfish.


00:16:59.920 --> 00:17:01.910
The authors compared various areas of


00:17:01.920 --> 00:17:03.670
the great barrier reef that have either


00:17:03.680 --> 00:17:05.909
banned fishing, have limited it, or have


00:17:05.919 --> 00:17:08.309
no restrictions on it. They found in


00:17:08.319 --> 00:17:10.150
areas that banned fishing, there was a


00:17:10.160 --> 00:17:13.029
2.8 8 to 3.6 times higher chance of


00:17:13.039 --> 00:17:15.350
crown of thorns being eaten by predatory


00:17:15.360 --> 00:17:18.069
fish. The authors say the elevated risk


00:17:18.079 --> 00:17:20.150
of the spiny critters in no fishing


00:17:20.160 --> 00:17:22.470
reserves is directly attributable to a


00:17:22.480 --> 00:17:24.710
single species of snapper known as the


00:17:24.720 --> 00:17:27.029
Spangot Emperor, which has some 6.3


00:17:27.039 --> 00:17:29.190
times greater biomass in no fishing


00:17:29.200 --> 00:17:31.430
areas versus those areas where fishing


00:17:31.440 --> 00:17:33.750
is allowed.


00:17:33.760 --> 00:17:35.909
Scientists say glass could be the future


00:17:35.919 --> 00:17:38.310
of long-term data storage for human


00:17:38.320 --> 00:17:40.630
knowledge and recordkeeping. Current


00:17:40.640 --> 00:17:42.549
data preservation techniques such as


00:17:42.559 --> 00:17:44.870
tapes and hard drives tend to degrade


00:17:44.880 --> 00:17:47.110
within a few years or decades and are


00:17:47.120 --> 00:17:49.110
therefore unreliable for long-term


00:17:49.120 --> 00:17:51.830
storage. However, by using lasers to


00:17:51.840 --> 00:17:53.909
encode data onto glass, data could


00:17:53.919 --> 00:17:55.830
withstand moisture, temperature changes,


00:17:55.840 --> 00:17:57.669
and electromagnetic interference for


00:17:57.679 --> 00:17:59.830
centuries. A report in the journal


00:17:59.840 --> 00:18:02.390
Nature claims the system can store 4.8 8


00:18:02.400 --> 00:18:05.190
terabt of data in a 12x 12 cm glass


00:18:05.200 --> 00:18:07.590
sheet with a shelf life of up to 10,000


00:18:07.600 --> 00:18:09.510
years even if stored at high


00:18:09.520 --> 00:18:11.669
temperatures.


00:18:11.679 --> 00:18:13.190
Google have finally launched the new


00:18:13.200 --> 00:18:15.750
Pixel 10a smartphone which one must


00:18:15.760 --> 00:18:17.830
admit is strikingly similar to the


00:18:17.840 --> 00:18:20.549
earlier Pixel 9a. With the details,


00:18:20.559 --> 00:18:22.789
we're joined by technology editor Alex


00:18:22.799 --> 00:18:24.870
Royo from Techadvice St.Life.


00:18:24.880 --> 00:18:27.029
>> Yeah, this is the Pixel 10A. So, this is


00:18:27.039 --> 00:18:29.909
the lower cost version of Google's Pixel


00:18:29.919 --> 00:18:31.669
phones. They normally have the the


00:18:31.679 --> 00:18:34.070
regular Pixel 10 and the the 10 Pro and


00:18:34.080 --> 00:18:35.990
also the 10 Pro XL which is a larger


00:18:36.000 --> 00:18:38.150
version. And then around about this time


00:18:38.160 --> 00:18:40.070
every year, they launch the A version


00:18:40.080 --> 00:18:41.909
which is their more affordable version.


00:18:41.919 --> 00:18:44.390
So this one is $849 Australian,


00:18:44.400 --> 00:18:46.310
obviously less in US dollars, but it


00:18:46.320 --> 00:18:48.390
competes against all those phones that


00:18:48.400 --> 00:18:51.029
are $500 or less, which generally are


00:18:51.039 --> 00:18:53.270
not terribly great phones. I mean that


00:18:53.280 --> 00:18:54.390
look, they'll do what you want them to


00:18:54.400 --> 00:18:55.590
do. They'll do maps, they'll do


00:18:55.600 --> 00:18:56.870
messaging, they'll do various things.


00:18:56.880 --> 00:18:58.310
But if you try and push them with games


00:18:58.320 --> 00:19:00.150
or just try and I don't know do lots of


00:19:00.160 --> 00:19:01.669
video editing or whatever it might be,


00:19:01.679 --> 00:19:03.750
they're clearly not going to be as


00:19:03.760 --> 00:19:06.470
performant as the uh the major devices.


00:19:06.480 --> 00:19:08.150
And that's where the Pixel 10a and also


00:19:08.160 --> 00:19:10.710
the iPhone 16 and the forthcoming 710A,


00:19:10.720 --> 00:19:11.990
which we'll talk about in a moment, come


00:19:12.000 --> 00:19:13.990
in as almost flagship phones under


00:19:14.000 --> 00:19:16.390
$1,000. Now, the one thing that is


00:19:16.400 --> 00:19:18.310
interesting this year is that whilst the


00:19:18.320 --> 00:19:21.350
10 and 10 Pro have the Tensor G5 chip,


00:19:21.360 --> 00:19:23.430
the 1080 this year does not. It has the


00:19:23.440 --> 00:19:25.270
G4 which is a bit unusual because


00:19:25.280 --> 00:19:26.950
normally you know you you would be


00:19:26.960 --> 00:19:28.470
putting the latest chip but clearly in


00:19:28.480 --> 00:19:31.669
an era where memory storage and even the


00:19:31.679 --> 00:19:33.430
space to make processes or more


00:19:33.440 --> 00:19:35.270
expensive processes on production lines


00:19:35.280 --> 00:19:37.830
is heavily impacted by all of the GPUs


00:19:37.840 --> 00:19:40.630
and uh AI in data centers most of which


00:19:40.640 --> 00:19:41.990
actually hasn't been built yet. It's


00:19:42.000 --> 00:19:43.510
sort of been pre-ordered to fulfill


00:19:43.520 --> 00:19:45.029
demand that it's theoretically supposed


00:19:45.039 --> 00:19:45.590
to be there.


00:19:45.600 --> 00:19:47.510
>> There's finally a date for the Apple


00:19:47.520 --> 00:19:48.070
premiere.


00:19:48.080 --> 00:19:50.230
>> Yeah. So this is March 4th in New York.


00:19:50.240 --> 00:19:52.070
They'll also be holding events within


00:19:52.080 --> 00:19:53.669
Singapore and London. This is where


00:19:53.679 --> 00:19:56.549
we're meant to hear about iPhones 17e


00:19:56.559 --> 00:19:58.549
which in theory will have the same chip


00:19:58.559 --> 00:20:00.150
that is in the iPhone 17 range but


00:20:00.160 --> 00:20:02.070
normally there's one core less for some


00:20:02.080 --> 00:20:03.990
reason. It's like a bind chip one of the


00:20:04.000 --> 00:20:05.350
graphics cores or one of one of the


00:20:05.360 --> 00:20:08.070
cores is not there. So it enables Apple


00:20:08.080 --> 00:20:09.669
to use these chips which still have


00:20:09.679 --> 00:20:11.350
great power but in their cheapest device


00:20:11.360 --> 00:20:14.070
$999 in Australia is what the 16 sells


00:20:14.080 --> 00:20:15.590
for. I expect the price will be the


00:20:15.600 --> 00:20:17.590
same. But more importantly, we are


00:20:17.600 --> 00:20:20.310
expecting to also see the new MacBook.


00:20:20.320 --> 00:20:22.710
Supposedly 12 in screen, so small. I


00:20:22.720 --> 00:20:24.310
mean, I've heard people say 13 in, but


00:20:24.320 --> 00:20:26.789
effectively this will sell presumably in


00:20:26.799 --> 00:20:29.270
the US for about $599. We're yet to find


00:20:29.280 --> 00:20:31.270
out. Supposedly, it only has 8 gig of


00:20:31.280 --> 00:20:33.270
RAM instead of 16, which you would think


00:20:33.280 --> 00:20:35.190
is not as enough as you would have on


00:20:35.200 --> 00:20:37.110
the 16 gig devices that can better run


00:20:37.120 --> 00:20:38.630
Apple intelligence, although we're still


00:20:38.640 --> 00:20:40.310
waiting for the next generation of Siri.


00:20:40.320 --> 00:20:42.310
But this will be a lowc cost Mac running


00:20:42.320 --> 00:20:45.190
an iPhone chip with iPhone chips very


00:20:45.200 --> 00:20:47.190
powerful. I mean uh the latest chips are


00:20:47.200 --> 00:20:49.110
as good as the or better than the M1


00:20:49.120 --> 00:20:51.510
from 5 years ago. And uh that's still a


00:20:51.520 --> 00:20:53.110
great computer. I have an M1 with 8 gig


00:20:53.120 --> 00:20:55.430
of RAM and a 512 gig SSD and it's


00:20:55.440 --> 00:20:57.830
running everything that my M2 with 24


00:20:57.840 --> 00:21:00.630
ter GB of RAM and a 1 TB SSD can run.


00:21:00.640 --> 00:21:03.190
So, if Apple does that, it will mean


00:21:03.200 --> 00:21:05.270
greater competition for the school


00:21:05.280 --> 00:21:07.029
dollar where you've got Chromebooks and


00:21:07.039 --> 00:21:08.710
you've got iPads and tablets and but


00:21:08.720 --> 00:21:10.710
it'll also give people a cheaper Mac to


00:21:10.720 --> 00:21:13.029
to go for and then they once they start


00:21:13.039 --> 00:21:15.029
using it, they can aspire to better. But


00:21:15.039 --> 00:21:17.110
it will be certainly better than any


00:21:17.120 --> 00:21:19.990
Windows PC that is in the $500,000


00:21:20.000 --> 00:21:21.510
market. It'll just be a vastly better


00:21:21.520 --> 00:21:23.270
device with all the advantages of the


00:21:23.280 --> 00:21:23.669
Macs.


00:21:23.679 --> 00:21:25.029
>> Price of hard drives are going up. the


00:21:25.039 --> 00:21:26.230
cost of these things are going up and


00:21:26.240 --> 00:21:28.070
Western Digital has reported or it's


00:21:28.080 --> 00:21:29.510
been reported online that it has sold


00:21:29.520 --> 00:21:32.870
its entire 2026 allocation of discs to


00:21:32.880 --> 00:21:35.190
data centers. I mean I presume this you


00:21:35.200 --> 00:21:36.950
know still obviously discs in the


00:21:36.960 --> 00:21:39.750
channel uh for consumers but it sold its


00:21:39.760 --> 00:21:41.909
entire 2026 contingent and apparently it


00:21:41.919 --> 00:21:44.230
sold part of its 2027 and 2028


00:21:44.240 --> 00:21:46.470
contingent as well. So the need for


00:21:46.480 --> 00:21:49.110
hardware and electricity to power it is


00:21:49.120 --> 00:21:50.789
paramount. If uh anything's going to


00:21:50.799 --> 00:21:52.390
slow down the revolution, it's going to


00:21:52.400 --> 00:21:54.310
be not having enough of these drives and


00:21:54.320 --> 00:21:56.549
memory and and other GPUs components.


00:21:56.559 --> 00:21:58.390
But I guess the companies buying them up


00:21:58.400 --> 00:22:00.470
in in such volume, making sure that you


00:22:00.480 --> 00:22:02.390
know the data center guys will be okay.


00:22:02.400 --> 00:22:03.909
But it's consumers and businesses that


00:22:03.919 --> 00:22:05.430
will suffer with higher prices.


00:22:05.440 --> 00:22:09.110
