00:00:00.400 --> 00:00:03.510
Hello and welcome to Astronomy Daily,


00:00:03.520 --> 00:00:05.829
your daily guide to what's happening in


00:00:05.839 --> 00:00:07.670
space. I'm Anna.


00:00:07.680 --> 00:00:10.629
>> And I'm Avery. It is Tuesday, February


00:00:10.639 --> 00:00:14.230
24th, 2026, and we have a busy show for


00:00:14.240 --> 00:00:15.190
you today.


00:00:15.200 --> 00:00:17.670
>> We do. The big headline, the one


00:00:17.680 --> 00:00:19.510
everyone in the space community is


00:00:19.520 --> 00:00:22.230
talking about right now, is Artemis. And


00:00:22.240 --> 00:00:24.310
specifically, what is happening to that


00:00:24.320 --> 00:00:27.269
rocket at this very moment? Quite


00:00:27.279 --> 00:00:29.589
literally as we record this, the SLS


00:00:29.599 --> 00:00:32.470
rocket is making a very slow journey


00:00:32.480 --> 00:00:36.630
about 1 mph back to its garage. We have


00:00:36.640 --> 00:00:39.190
all the details on that. We also have a


00:00:39.200 --> 00:00:41.990
genuinely exciting story from Mars, a


00:00:42.000 --> 00:00:43.990
wild mission concept to chase an


00:00:44.000 --> 00:00:46.869
interstellar comet. China's mystery


00:00:46.879 --> 00:00:49.350
space plane is back in orbit. And we


00:00:49.360 --> 00:00:51.510
wrap up with some beautiful red giant


00:00:51.520 --> 00:00:53.510
science that solves a mystery that's


00:00:53.520 --> 00:00:55.590
been bugging astronomers since the


00:00:55.600 --> 00:00:57.270
1970s.


00:00:57.280 --> 00:00:59.349
>> Plus, we run through this week's launch


00:00:59.359 --> 00:01:01.510
schedule, and it is surprisingly busy


00:01:01.520 --> 00:01:03.990
despite all the Aremis drama. Let's get


00:01:04.000 --> 00:01:05.030
into it.


00:01:05.040 --> 00:01:07.429
>> So, Avery, let's start with Artemis


00:01:07.439 --> 00:01:09.429
because this is a story that has taken


00:01:09.439 --> 00:01:12.230
yet another dramatic turn. Honestly,


00:01:12.240 --> 00:01:14.310
Anna, this one stings a little because


00:01:14.320 --> 00:01:16.230
just last week we were watching a really


00:01:16.240 --> 00:01:18.630
successful second wet dress rehearsal


00:01:18.640 --> 00:01:21.109
and NASA was talking about March 6th as


00:01:21.119 --> 00:01:23.190
a real launch date. Things were looking


00:01:23.200 --> 00:01:24.070
good.


00:01:24.080 --> 00:01:26.390
>> And then Saturday happened


00:01:26.400 --> 00:01:28.870
>> and then Saturday happened. Overnight on


00:01:28.880 --> 00:01:30.870
February 21st, engineers noticed


00:01:30.880 --> 00:01:33.030
something concerning, an interruption in


00:01:33.040 --> 00:01:35.270
the flow of helium to the rocket's upper


00:01:35.280 --> 00:01:37.429
stage, specifically the interim


00:01:37.439 --> 00:01:41.190
cryogenic propulsion stage or ICPS.


00:01:41.200 --> 00:01:43.109
And just to be clear for listeners who


00:01:43.119 --> 00:01:45.190
might be newer to the show, what does


00:01:45.200 --> 00:01:47.910
the ICPS actually do?


00:01:47.920 --> 00:01:50.469
>> Great question. The ICPS is the upper


00:01:50.479 --> 00:01:52.950
stage of the SLS rocket. It sits above


00:01:52.960 --> 00:01:55.109
the core stage and it's what fires to


00:01:55.119 --> 00:01:57.990
push Orion and the crew on their trans


00:01:58.000 --> 00:02:00.469
lunar trajectory toward the moon. It


00:02:00.479 --> 00:02:02.950
uses helium internally to do two


00:02:02.960 --> 00:02:04.950
critical jobs. It maintains


00:02:04.960 --> 00:02:06.789
environmental conditions around its


00:02:06.799 --> 00:02:09.510
engine and it pressurizes the liquid


00:02:09.520 --> 00:02:11.830
hydrogen and liquid oxygen propellant


00:02:11.840 --> 00:02:15.030
tanks. So helium is not optional. Helium


00:02:15.040 --> 00:02:16.630
is fundamental.


00:02:16.640 --> 00:02:18.630
>> And this helium flow issue appeared


00:02:18.640 --> 00:02:20.390
after the wet dress rehearsal had


00:02:20.400 --> 00:02:23.190
completed, not during it, which makes it


00:02:23.200 --> 00:02:25.670
particularly tricky to pin down.


00:02:25.680 --> 00:02:28.869
>> Exactly. The WDR itself went smoothly.


00:02:28.879 --> 00:02:31.110
It was during reconfiguration afterward


00:02:31.120 --> 00:02:33.589
that data showed the interruption. NASA


00:02:33.599 --> 00:02:35.830
administrator Jared Isaacman posted


00:02:35.840 --> 00:02:37.670
about it on Saturday, saying the team


00:02:37.680 --> 00:02:40.550
was investigating three possible causes.


00:02:40.560 --> 00:02:42.710
A blocked filter between the vehicle and


00:02:42.720 --> 00:02:45.430
ground support equipment, a failed quick


00:02:45.440 --> 00:02:47.910
disconnect umbilical interface, or a


00:02:47.920 --> 00:02:50.070
failed check valve on the vehicle,


00:02:50.080 --> 00:02:52.309
similar to what caused delays on Artemis


00:02:52.319 --> 00:02:53.110
1.


00:02:53.120 --> 00:02:55.110
>> And regardless of which of those three


00:02:55.120 --> 00:02:57.589
it turns out to be, the answer is the


00:02:57.599 --> 00:02:58.550
same.


00:02:58.560 --> 00:03:01.110
>> The answer is always the same. They have


00:03:01.120 --> 00:03:02.949
to go back to the vehicle assembly


00:03:02.959 --> 00:03:05.110
building. You can't fix any of those


00:03:05.120 --> 00:03:07.589
things on the launchpad. So NASA


00:03:07.599 --> 00:03:09.830
confirmed a roll back and that roll back


00:03:09.840 --> 00:03:12.949
is happening today, February 24th. The


00:03:12.959 --> 00:03:15.670
SLS, Orion, and the whole stack are


00:03:15.680 --> 00:03:18.149
being loaded onto the crawler and making


00:03:18.159 --> 00:03:22.149
that 4.2 mile journey back to the VAB at


00:03:22.159 --> 00:03:24.229
roughly 1 mph,


00:03:24.239 --> 00:03:27.190
>> which takes several hours. It is not a


00:03:27.200 --> 00:03:29.830
fast vehicle. It's not. The crawler


00:03:29.840 --> 00:03:32.470
itself weighs about 6 12 million pounds


00:03:32.480 --> 00:03:35.830
unloaded and it's burning around 165


00:03:35.840 --> 00:03:38.710
gall of diesel per mile. It is an


00:03:38.720 --> 00:03:40.550
extraordinary piece of engineering in


00:03:40.560 --> 00:03:41.910
its own right.


00:03:41.920 --> 00:03:43.589
>> So where does this leave the mission


00:03:43.599 --> 00:03:44.710
timeline?


00:03:44.720 --> 00:03:46.949
>> March is definitively off the table.


00:03:46.959 --> 00:03:49.430
Isaac man was very clear about that.


00:03:49.440 --> 00:03:51.350
April is now the earliest possible


00:03:51.360 --> 00:03:53.350
window and NASA has said that quick


00:03:53.360 --> 00:03:55.589
action to get back to the VAB could


00:03:55.599 --> 00:03:57.910
still preserve April. A full media


00:03:57.920 --> 00:04:00.070
briefing is expected this week. The


00:04:00.080 --> 00:04:02.390
crew, commander Reed Weisman, pilot


00:04:02.400 --> 00:04:04.470
Victor Glover, mission specialist


00:04:04.480 --> 00:04:06.789
Christina Ko, and Canadian astronaut


00:04:06.799 --> 00:04:09.110
Jeremy Hansen had just entered


00:04:09.120 --> 00:04:10.869
quarantine and have now been released


00:04:10.879 --> 00:04:13.110
again. This would be their second exit


00:04:13.120 --> 00:04:14.550
from quarantine,


00:04:14.560 --> 00:04:16.789
>> which tells you something about how hard


00:04:16.799 --> 00:04:19.189
this process has been. And this is still


00:04:19.199 --> 00:04:21.430
the first crude mission beyond low Earth


00:04:21.440 --> 00:04:25.270
orbit since Apollo 17 in 1972.


00:04:25.280 --> 00:04:27.670
The stakes are enormous.


00:04:27.680 --> 00:04:30.390
>> They really are. NASA's under pressure


00:04:30.400 --> 00:04:32.150
both from the public and from the White


00:04:32.160 --> 00:04:34.710
House to get this done. IsaacMen has


00:04:34.720 --> 00:04:36.150
been quite transparent about the


00:04:36.160 --> 00:04:38.390
challenges, which is appreciated. We'll


00:04:38.400 --> 00:04:39.990
keep you updated as the investigation


00:04:40.000 --> 00:04:42.310
progresses. A media briefing is expected


00:04:42.320 --> 00:04:43.350
this week.


00:04:43.360 --> 00:04:45.270
>> Okay, let's lift the mood a little


00:04:45.280 --> 00:04:47.830
because our next story is genuinely


00:04:47.840 --> 00:04:50.469
brilliant and it comes from Mars.


00:04:50.479 --> 00:04:52.390
>> This is one of my favorites of the week.


00:04:52.400 --> 00:04:54.710
NASA's Perseverance rover has just been


00:04:54.720 --> 00:04:56.230
given something that effectively


00:04:56.240 --> 00:04:59.350
functions as GPS on a planet that has no


00:04:59.360 --> 00:05:01.590
GPS satellites whatsoever.


00:05:01.600 --> 00:05:04.230
>> So, how do you navigate on Mars? Walk us


00:05:04.240 --> 00:05:05.990
through how it used to work.


00:05:06.000 --> 00:05:08.550
>> So, historically, Perseverance used a


00:05:08.560 --> 00:05:11.350
system called visual odometry. Every few


00:05:11.360 --> 00:05:13.270
feet, it takes camera images of the


00:05:13.280 --> 00:05:14.790
surrounding rocks and geological


00:05:14.800 --> 00:05:16.629
features, and it tracks how those


00:05:16.639 --> 00:05:19.110
features shift in frame to estimate how


00:05:19.120 --> 00:05:21.670
far it's moved. It's clever, but the


00:05:21.680 --> 00:05:24.550
problem is that tiny errors add up. On a


00:05:24.560 --> 00:05:26.710
long drive, the rover's internal sense


00:05:26.720 --> 00:05:28.790
of where it is could be off by more than


00:05:28.800 --> 00:05:32.550
35 m. That's over 100 ft. When it hit


00:05:32.560 --> 00:05:34.310
that threshold of uncertainty, its


00:05:34.320 --> 00:05:35.990
safety systems would kick in and it


00:05:36.000 --> 00:05:37.189
would just stop and wait for


00:05:37.199 --> 00:05:38.790
instructions from Earth.


00:05:38.800 --> 00:05:40.870
>> And with communication delays of up to


00:05:40.880 --> 00:05:43.590
24 hours, that could mean an entire day


00:05:43.600 --> 00:05:45.670
of lost exploration time.


00:05:45.680 --> 00:05:48.310
>> Exactly. So NASA's Jet Propulsion Lab


00:05:48.320 --> 00:05:50.150
developed a new system called Mars


00:05:50.160 --> 00:05:52.310
Global Localization. Here's how it


00:05:52.320 --> 00:05:55.749
works. Perseverance takes a full 360°


00:05:55.759 --> 00:05:58.150
panorama with its navigation cameras.


00:05:58.160 --> 00:06:00.230
Then an algorithm compares that ground


00:06:00.240 --> 00:06:02.469
level view with highresolution orbital


00:06:02.479 --> 00:06:04.469
maps captured by the Mars Reconnaissance


00:06:04.479 --> 00:06:06.710
Orbiter far above. It matches the


00:06:06.720 --> 00:06:09.350
terrain, the ridges, rocks, slopes, and


00:06:09.360 --> 00:06:11.830
triangulates an exact position. The


00:06:11.840 --> 00:06:14.469
whole process takes about 2 minutes. 2


00:06:14.479 --> 00:06:17.590
minutes to know where you are with 25 cm


00:06:17.600 --> 00:06:20.309
accuracy. That is remarkable.


00:06:20.319 --> 00:06:22.629
>> What makes it even clever is where the


00:06:22.639 --> 00:06:25.029
computing power comes from. It runs on


00:06:25.039 --> 00:06:26.870
the helicopter base station, the


00:06:26.880 --> 00:06:28.790
processor that Perseverance used to


00:06:28.800 --> 00:06:31.270
communicate with Ingenuity. Ingenuity


00:06:31.280 --> 00:06:34.309
fluid's 72nd and final flight last year.


00:06:34.319 --> 00:06:36.870
So that processor was sitting idle. It


00:06:36.880 --> 00:06:39.350
runs more than 100 times faster than the


00:06:39.360 --> 00:06:41.590
rover's main computers. The team


00:06:41.600 --> 00:06:44.230
essentially repurposed it. So ingenuity


00:06:44.240 --> 00:06:46.550
keeps giving even in retirement.


00:06:46.560 --> 00:06:49.270
>> It really does. Bars global localization


00:06:49.280 --> 00:06:51.110
was used successfully for the first time


00:06:51.120 --> 00:06:53.110
in regular mission operations on


00:06:53.120 --> 00:06:56.550
February 2nd and again on February 16th.


00:06:56.560 --> 00:06:58.710
JPL's chief engineer of robotics


00:06:58.720 --> 00:07:01.029
operations, Vandy Verma, described it as


00:07:01.039 --> 00:07:03.909
giving the rover GPS, saying it can now


00:07:03.919 --> 00:07:05.510
drive for potentially unlimited


00:07:05.520 --> 00:07:07.670
distances without calling home.


00:07:07.680 --> 00:07:09.909
>> And this has implications beyond just


00:07:09.919 --> 00:07:11.270
Mars, doesn't it?


00:07:11.280 --> 00:07:13.670
>> Big implications. NASA's already looking


00:07:13.680 --> 00:07:15.510
at adapting this for future lunar


00:07:15.520 --> 00:07:17.029
missions where you have difficult


00:07:17.039 --> 00:07:19.430
lighting conditions and long cold nights


00:07:19.440 --> 00:07:21.830
that make precise location data even


00:07:21.840 --> 00:07:23.749
more critical. And if we ever have


00:07:23.759 --> 00:07:25.830
astronauts driving pressurized rovers on


00:07:25.840 --> 00:07:27.589
Mars, they won't be able to wait for


00:07:27.599 --> 00:07:29.670
Houston to tell them where they are.


00:07:29.680 --> 00:07:31.670
This is exactly the kind of technology


00:07:31.680 --> 00:07:32.790
they'll need.


00:07:32.800 --> 00:07:35.589
>> What a story. 5 years on Mars and


00:07:35.599 --> 00:07:38.070
Perseverance just keeps getting smarter.


00:07:38.080 --> 00:07:40.870
>> And hopefully so are we. Now, this next


00:07:40.880 --> 00:07:43.350
story, I love this one because it is


00:07:43.360 --> 00:07:45.830
genuinely audacious. We're talking about


00:07:45.840 --> 00:07:47.749
a mission concept that was published


00:07:47.759 --> 00:07:49.909
this week for chasing down an


00:07:49.919 --> 00:07:53.110
interstellar comet. Avery set the scene.


00:07:53.120 --> 00:07:54.790
>> Right. So, our audience will remember


00:07:54.800 --> 00:07:57.670
comet 3i/ATLS,


00:07:57.680 --> 00:07:59.830
the third confirmed interstellar object


00:07:59.840 --> 00:08:01.909
ever detected in our solar system,


00:08:01.919 --> 00:08:04.869
discovered in July 2025. It came


00:08:04.879 --> 00:08:06.790
screaming through from outside the solar


00:08:06.800 --> 00:08:08.950
system, made its closest approach to the


00:08:08.960 --> 00:08:11.830
sun last October, swung past Venus in


00:08:11.840 --> 00:08:14.230
November, and came closest to Earth in


00:08:14.240 --> 00:08:16.950
December. It is now racing away from us


00:08:16.960 --> 00:08:19.510
at over 60 km/s,


00:08:19.520 --> 00:08:22.230
>> which is extraordinarily fast. For


00:08:22.240 --> 00:08:24.230
context, that's faster than any


00:08:24.240 --> 00:08:27.270
spacecraft humanity has ever launched.


00:08:27.280 --> 00:08:29.749
>> Much faster. And that speed is the whole


00:08:29.759 --> 00:08:32.149
problem. Researchers from the Initiative


00:08:32.159 --> 00:08:34.550
for Interstellar Studies published new


00:08:34.560 --> 00:08:37.029
work this week exploring how you could


00:08:37.039 --> 00:08:39.350
actually send a spacecraft to intercept


00:08:39.360 --> 00:08:42.469
it. The short answer is you need to do


00:08:42.479 --> 00:08:45.110
something genuinely extreme. They call


00:08:45.120 --> 00:08:47.910
it a solar oirth maneuver.


00:08:47.920 --> 00:08:49.670
>> Explain that to us.


00:08:49.680 --> 00:08:52.070
>> So the oirth effect is actually a


00:08:52.080 --> 00:08:54.550
principle used in basically every rocket


00:08:54.560 --> 00:08:56.870
launch. It says that if you fire your


00:08:56.880 --> 00:08:59.110
engines when you're moving fast, you get


00:08:59.120 --> 00:09:01.110
a bigger boost than if you fire them


00:09:01.120 --> 00:09:03.670
when you're going slowly. Normally, it's


00:09:03.680 --> 00:09:05.509
applied when a spacecraft is at the


00:09:05.519 --> 00:09:07.829
closest point of its orbit around the


00:09:07.839 --> 00:09:10.470
planet. What this mission proposes is


00:09:10.480 --> 00:09:13.190
doing it at the closest point of a solar


00:09:13.200 --> 00:09:16.389
orbit, a literal close flyby of the sun


00:09:16.399 --> 00:09:19.990
itself. We're talking 3.2 solar radi


00:09:20.000 --> 00:09:22.550
from the sun's surface. That is


00:09:22.560 --> 00:09:25.670
extremely close. How close is that?


00:09:25.680 --> 00:09:26.550
Actually,


00:09:26.560 --> 00:09:28.710
>> to put it in perspective, the Parker


00:09:28.720 --> 00:09:31.509
Solar Probe goes closer, but even that


00:09:31.519 --> 00:09:33.350
is an extraordinary engineering


00:09:33.360 --> 00:09:35.829
challenge. At that distance, the heat


00:09:35.839 --> 00:09:38.470
and radiation are intense. The


00:09:38.480 --> 00:09:41.030
spacecraft would need serious shielding.


00:09:41.040 --> 00:09:43.190
But the gravitational kick from firing


00:09:43.200 --> 00:09:46.230
your engines that close to the sun is so


00:09:46.240 --> 00:09:48.070
powerful that you could theoretically


00:09:48.080 --> 00:09:50.389
reach speeds never achieved by


00:09:50.399 --> 00:09:53.430
human-made objects. And then you'd still


00:09:53.440 --> 00:09:57.750
need how long to actually reach 3i-atls?


00:09:57.760 --> 00:10:00.310
>> If launched in 2025, which the


00:10:00.320 --> 00:10:02.310
researchers identify as the optimal


00:10:02.320 --> 00:10:04.630
window based on the alignment of Earth,


00:10:04.640 --> 00:10:07.430
Jupiter, the sun, and the comet, the


00:10:07.440 --> 00:10:10.710
spacecraft would reach 3-TLS


00:10:10.720 --> 00:10:13.110
by around 2085


00:10:13.120 --> 00:10:16.630
at a distance of approximately 732


00:10:16.640 --> 00:10:19.269
astronomical units from the sun. For


00:10:19.279 --> 00:10:21.910
comparison, Voyager 1 has been traveling


00:10:21.920 --> 00:10:25.910
for nearly 50 years and is only at about


00:10:25.920 --> 00:10:27.430
170 AU.


00:10:27.440 --> 00:10:30.069
>> So this would be the most distant rende


00:10:30.079 --> 00:10:32.150
view in human history


00:10:32.160 --> 00:10:35.190
>> by a massive margin. And only a flyby


00:10:35.200 --> 00:10:37.910
would be possible, not orbit insertion


00:10:37.920 --> 00:10:39.829
because both the spacecraft and the


00:10:39.839 --> 00:10:42.710
comet would be moving so fast. But even


00:10:42.720 --> 00:10:45.670
a flyby would be extraordinary because


00:10:45.680 --> 00:10:47.910
3II-TLS


00:10:47.920 --> 00:10:50.470
didn't form in our solar system. It


00:10:50.480 --> 00:10:52.470
formed around the different star,


00:10:52.480 --> 00:10:55.430
possibly one that no longer exists. Its


00:10:55.440 --> 00:10:57.190
chemical fingerprints could tell us


00:10:57.200 --> 00:10:59.110
things about planetary formation


00:10:59.120 --> 00:11:01.590
elsewhere in the galaxy that we simply


00:11:01.600 --> 00:11:03.829
cannot learn any other way.


00:11:03.839 --> 00:11:05.670
>> It's one of those stories where the


00:11:05.680 --> 00:11:08.069
scale of ambition just takes your breath


00:11:08.079 --> 00:11:10.470
away. Is there any serious movement


00:11:10.480 --> 00:11:12.310
toward actually doing this?


00:11:12.320 --> 00:11:14.389
>> The researchers are clear this is a


00:11:14.399 --> 00:11:17.829
proposal, not a funded mission. But 2035


00:11:17.839 --> 00:11:20.550
is only 9 years away. Decisions would


00:11:20.560 --> 00:11:23.269
need to start being made soon. And three


00:11:23.279 --> 00:11:25.590
Atlas won't be the last interstellar


00:11:25.600 --> 00:11:28.310
visitor. The more of these we find, the


00:11:28.320 --> 00:11:30.470
more valuable the case for chasing one


00:11:30.480 --> 00:11:32.790
becomes. Staying in the realm of things


00:11:32.800 --> 00:11:35.110
we don't know much about, let's talk


00:11:35.120 --> 00:11:37.670
about China's Shenlong spacecraft, which


00:11:37.680 --> 00:11:39.590
launched on its fourth mission earlier


00:11:39.600 --> 00:11:42.150
this month. Shenl Long, which means


00:11:42.160 --> 00:11:44.550
divine dragon in Chinese, is one of


00:11:44.560 --> 00:11:46.470
those topics that generates a lot of


00:11:46.480 --> 00:11:49.110
fascination precisely because so little


00:11:49.120 --> 00:11:51.829
is officially confirmed. This is China's


00:11:51.839 --> 00:11:54.630
reusable robotic space plane. Broadly


00:11:54.640 --> 00:11:58.470
analogist to the US Air Force's X37B,


00:11:58.480 --> 00:12:00.389
it launched from the Ju Kuan satellite


00:12:00.399 --> 00:12:03.110
launch center on February 6th or 7th


00:12:03.120 --> 00:12:05.910
aboard a Long March 2F rocket.


00:12:05.920 --> 00:12:09.430
>> And as usual, China hasn't said much.


00:12:09.440 --> 00:12:11.829
>> Extremely little. The official line via


00:12:11.839 --> 00:12:14.389
state media Shin Wa is that the mission


00:12:14.399 --> 00:12:16.629
will conduct quote technology


00:12:16.639 --> 00:12:18.949
verification and will provide technical


00:12:18.959 --> 00:12:21.829
support for the peaceful use of space.


00:12:21.839 --> 00:12:23.670
No launch time was given, no


00:12:23.680 --> 00:12:26.069
photographs, no mission duration,


00:12:26.079 --> 00:12:27.110
nothing.


00:12:27.120 --> 00:12:28.870
>> But we can look at what the previous


00:12:28.880 --> 00:12:30.550
missions have done and draw some


00:12:30.560 --> 00:12:31.829
inferences.


00:12:31.839 --> 00:12:34.629
>> We can The first mission in September


00:12:34.639 --> 00:12:38.870
2020 lasted 2 days. The second in 2022


00:12:38.880 --> 00:12:42.870
lasted 276 days. The third launched


00:12:42.880 --> 00:12:47.750
December 2023 lasted 268 days. So recent


00:12:47.760 --> 00:12:49.750
missions have been around 9 months in


00:12:49.760 --> 00:12:52.310
orbit. If this one follows the pattern,


00:12:52.320 --> 00:12:54.310
we might expect it to return around


00:12:54.320 --> 00:12:56.150
November or December.


00:12:56.160 --> 00:12:58.470
>> And what have analysts pieced together


00:12:58.480 --> 00:13:00.710
about what it does up there?


00:13:00.720 --> 00:13:03.030
>> This is where it gets interesting.


00:13:03.040 --> 00:13:05.430
Western space tracking organizations,


00:13:05.440 --> 00:13:07.910
including the US space force and private


00:13:07.920 --> 00:13:10.310
space situational awareness companies,


00:13:10.320 --> 00:13:12.310
have observed that Shenlong conducts


00:13:12.320 --> 00:13:14.870
what are called rendevous and proximity


00:13:14.880 --> 00:13:17.670
operations. It maneuvers close to other


00:13:17.680 --> 00:13:20.550
objects in orbit. It has deployed small


00:13:20.560 --> 00:13:23.350
objects, possible subsatellites, during


00:13:23.360 --> 00:13:25.910
at least two previous missions. One of


00:13:25.920 --> 00:13:27.990
those objects was observed transmitting


00:13:28.000 --> 00:13:30.629
signals over North America, leading some


00:13:30.639 --> 00:13:32.710
analysts to describe it as a potential


00:13:32.720 --> 00:13:35.430
mobile signals intelligence platform


00:13:35.440 --> 00:13:38.310
>> and the anti-satellite angle.


00:13:38.320 --> 00:13:40.870
>> Analysts are cautious. Some experts


00:13:40.880 --> 00:13:43.030
point out that Shenlong's small payload


00:13:43.040 --> 00:13:45.509
bay and limited power generation make it


00:13:45.519 --> 00:13:48.550
an unlikely direct space weapon. But the


00:13:48.560 --> 00:13:50.710
ability to approach other satellites at


00:13:50.720 --> 00:13:54.069
close range is inherently dual use. It


00:13:54.079 --> 00:13:55.670
could be inspection. It could be


00:13:55.680 --> 00:13:58.230
servicing. It could be something else.


00:13:58.240 --> 00:14:01.269
We genuinely don't know. What we do know


00:14:01.279 --> 00:14:04.870
is that the US X37B's eighth mission is


00:14:04.880 --> 00:14:07.030
also currently in orbit. Launched last


00:14:07.040 --> 00:14:09.670
August to test quantum inertial sensors


00:14:09.680 --> 00:14:12.310
and high bandwidth laser links. These


00:14:12.320 --> 00:14:14.150
are the only two countries flying


00:14:14.160 --> 00:14:16.470
reusable space planes right now. and


00:14:16.480 --> 00:14:18.710
they're both being quite secretive about


00:14:18.720 --> 00:14:19.430
it.


00:14:19.440 --> 00:14:22.069
>> The new space race conducted largely in


00:14:22.079 --> 00:14:23.269
silence.


00:14:23.279 --> 00:14:24.790
>> Perfectly put.


00:14:24.800 --> 00:14:26.870
>> Now, let's do a quick run through of


00:14:26.880 --> 00:14:28.470
what else is happening on the launch


00:14:28.480 --> 00:14:30.710
front this week. Because despite all the


00:14:30.720 --> 00:14:33.189
Aremis drama, the commercial sector does


00:14:33.199 --> 00:14:34.629
not stop.


00:14:34.639 --> 00:14:38.389
>> It really doesn't. Today, February 24th,


00:14:38.399 --> 00:14:40.389
we actually have a launch scheduled from


00:14:40.399 --> 00:14:43.030
Wallup's flight facility in Virginia.


00:14:43.040 --> 00:14:45.670
Rocket Lab's Haste rocket hypersonic


00:14:45.680 --> 00:14:49.110
accelerator suborbital test electron is


00:14:49.120 --> 00:14:51.269
carrying a fascinating payload called


00:14:51.279 --> 00:14:54.389
Dart AE. It's a scamjet powered


00:14:54.399 --> 00:14:56.629
hypersonic vehicle built by Brisbane


00:14:56.639 --> 00:14:59.189
based company hypersonics launch systems


00:14:59.199 --> 00:15:01.829
and this will be its first ever flight.


00:15:01.839 --> 00:15:03.910
The mission is nicknamed that's not a


00:15:03.920 --> 00:15:05.910
knife which we appreciate.


00:15:05.920 --> 00:15:08.150
>> Australian hypersonics delivered with


00:15:08.160 --> 00:15:09.990
Australian humor.


00:15:10.000 --> 00:15:13.110
>> Exactly. SpaceX also has a Falcon 9


00:15:13.120 --> 00:15:14.949
Starlink launch out of Cape Canaveral


00:15:14.959 --> 00:15:17.350
today. Wednesday brings another Starlink


00:15:17.360 --> 00:15:19.509
from Vandenberg, but the standout launch


00:15:19.519 --> 00:15:21.590
of the week is Friday. Firefly


00:15:21.600 --> 00:15:23.829
Aerospace's Alpha rocket is returning to


00:15:23.839 --> 00:15:26.389
flight on the Stairway to 7 mission.


00:15:26.399 --> 00:15:27.990
>> Tell us about that one.


00:15:28.000 --> 00:15:30.550
>> So Fireflyy's last alpha launch was in


00:15:30.560 --> 00:15:33.910
April 2025 and it ended in failure. The


00:15:33.920 --> 00:15:35.829
rocket had an anomaly and the mission


00:15:35.839 --> 00:15:38.710
was lost. This is their return to flight


00:15:38.720 --> 00:15:41.189
and it's significant for another reason.


00:15:41.199 --> 00:15:43.189
This will be the last flight of Alpha in


00:15:43.199 --> 00:15:45.590
its current block one configuration.


00:15:45.600 --> 00:15:47.750
They're upgrading to block 2 for flight


00:15:47.760 --> 00:15:50.550
8 which introduces in-house avionics and


00:15:50.560 --> 00:15:53.350
thermal improvements. So flight 7 is


00:15:53.360 --> 00:15:55.269
essentially a test bed for some of those


00:15:55.279 --> 00:15:57.910
new systems ahead of the full upgrade.


00:15:57.920 --> 00:15:59.430
>> A lot riding on it.


00:15:59.440 --> 00:16:02.389
>> Quite a lot. Then the week closes out on


00:16:02.399 --> 00:16:05.509
Sunday, March 1st with two more SpaceX


00:16:05.519 --> 00:16:08.150
Starlink missions, one from Vandenberg


00:16:08.160 --> 00:16:10.870
and one from Cape Canaveral. By the end


00:16:10.880 --> 00:16:13.430
of this week, SpaceX will have surpassed


00:16:13.440 --> 00:16:18.629
27 Falcon 9 launches for 2026 alone. The


00:16:18.639 --> 00:16:20.550
cadence is extraordinary.


00:16:20.560 --> 00:16:22.870
>> And all of this happening while the SLS


00:16:22.880 --> 00:16:25.749
is making its 1m hour journey back to


00:16:25.759 --> 00:16:28.710
the VAB. Quite the contrast. The


00:16:28.720 --> 00:16:31.590
juxaposition pretty much writes itself.


00:16:31.600 --> 00:16:33.990
>> And we close today with some beautiful


00:16:34.000 --> 00:16:36.710
deep science. A new study published this


00:16:36.720 --> 00:16:39.269
week in the journal Nature Astronomy has


00:16:39.279 --> 00:16:41.749
solved a mystery about red giant stars


00:16:41.759 --> 00:16:43.829
that have had astronomers puzzled since


00:16:43.839 --> 00:16:45.509
the 1970s.


00:16:45.519 --> 00:16:47.430
>> I love this one. So, a bit of


00:16:47.440 --> 00:16:49.749
background. Red giants are what stars


00:16:49.759 --> 00:16:52.069
like our sun become when they exhaust


00:16:52.079 --> 00:16:54.230
their hydrogen fuel. They expand


00:16:54.240 --> 00:16:56.230
dramatically and undergo chemical


00:16:56.240 --> 00:16:58.470
changes. One of the most striking


00:16:58.480 --> 00:17:00.629
observations has been a consistent


00:17:00.639 --> 00:17:03.509
decline in the ratio of carbon 12 to


00:17:03.519 --> 00:17:06.390
carbon 13 in their outer layers.


00:17:06.400 --> 00:17:08.549
Scientists knew this had to be caused by


00:17:08.559 --> 00:17:10.549
material rising up from the nuclear


00:17:10.559 --> 00:17:12.870
furnace in the core. But they could not


00:17:12.880 --> 00:17:15.110
figure out how that material crossed the


00:17:15.120 --> 00:17:17.510
stable barrier layer separating the core


00:17:17.520 --> 00:17:19.029
from the outer envelope


00:17:19.039 --> 00:17:20.069
>> until now.


00:17:20.079 --> 00:17:23.829
>> Until now. A team led by Simon Bluen at


00:17:23.839 --> 00:17:25.829
the University of Victoria's Astronomy


00:17:25.839 --> 00:17:27.909
Research Center working with colleagues


00:17:27.919 --> 00:17:30.230
at the University of Minnesota used


00:17:30.240 --> 00:17:31.830
cuttingedge three-dimensional


00:17:31.840 --> 00:17:34.390
hydrodnamic simulations to model the


00:17:34.400 --> 00:17:36.950
actual fluid dynamics inside a red


00:17:36.960 --> 00:17:39.909
giant. And they found the answer. It's


00:17:39.919 --> 00:17:40.950
rotation.


00:17:40.960 --> 00:17:43.350
>> Stellar rotation drives the mixing


00:17:43.360 --> 00:17:45.990
>> in a really dramatic way. Their


00:17:46.000 --> 00:17:48.150
simulations showed that in non-rotating


00:17:48.160 --> 00:17:50.710
stars, waves passing through the barrier


00:17:50.720 --> 00:17:52.950
layer transport very little material,


00:17:52.960 --> 00:17:55.270
which is what previous models predicted.


00:17:55.280 --> 00:17:58.070
But once you add rotation, it amplifies


00:17:58.080 --> 00:18:00.870
those waves enormously. Mixing rates


00:18:00.880 --> 00:18:03.750
exceed non-rotating stars by over 100


00:18:03.760 --> 00:18:06.230
times, and they increase with faster


00:18:06.240 --> 00:18:08.789
rotation rates. That matches exactly


00:18:08.799 --> 00:18:10.870
what we observe on real red giant


00:18:10.880 --> 00:18:11.590
surfaces.


00:18:11.600 --> 00:18:13.510
>> And these weren't small simulations.


00:18:13.520 --> 00:18:15.750
They used some serious computing power.


00:18:15.760 --> 00:18:18.310
>> Two supercomputers, the Texas Advanced


00:18:18.320 --> 00:18:20.870
Computing Center at UT Austin and the


00:18:20.880 --> 00:18:22.710
brand new Trillium Supercomputing


00:18:22.720 --> 00:18:24.789
Cluster at the University of Toronto's


00:18:24.799 --> 00:18:26.950
CINET facility. The principal


00:18:26.960 --> 00:18:29.190
investigator, Faulk Herurwig, described


00:18:29.200 --> 00:18:31.190
these as the most computationally


00:18:31.200 --> 00:18:33.669
intensive stellar convection simulations


00:18:33.679 --> 00:18:36.230
ever performed. They were only possible


00:18:36.240 --> 00:18:38.070
because of very recent advances in


00:18:38.080 --> 00:18:38.870
supercomputing.


00:18:38.880 --> 00:18:40.710
>> And what does this mean for us? For our


00:18:40.720 --> 00:18:43.669
son? In about five billion years, our


00:18:43.679 --> 00:18:46.070
sun will enter its red giant phase.


00:18:46.080 --> 00:18:49.270
It'll expand and likely swallow Mercury,


00:18:49.280 --> 00:18:51.909
Venus, and probably Earth. Beyond the


00:18:51.919 --> 00:18:55.029
frost line, Jupiter, Saturn, and beyond,


00:18:55.039 --> 00:18:56.789
those worlds will move into the new


00:18:56.799 --> 00:18:59.350
habitable zone. This research gives us


00:18:59.360 --> 00:19:01.430
much better predictions of exactly how


00:19:01.440 --> 00:19:03.590
our sun's chemistry will evolve during


00:19:03.600 --> 00:19:05.669
that transition. What elements will


00:19:05.679 --> 00:19:08.150
appear on its surface, how fast changes


00:19:08.160 --> 00:19:08.870
will occur,


00:19:08.880 --> 00:19:10.549
>> which sounds like a very long-term


00:19:10.559 --> 00:19:12.390
concern. But understanding how our star


00:19:12.400 --> 00:19:14.950
will die is genuinely important science.


00:19:14.960 --> 00:19:17.190
>> It is, and the techniques developed here


00:19:17.200 --> 00:19:19.669
have applications far beyond astronomy.


00:19:19.679 --> 00:19:21.750
The same simulation methods apply to


00:19:21.760 --> 00:19:24.390
ocean currents, atmospheric dynamics,


00:19:24.400 --> 00:19:27.110
even blood flow. Balkerwig is already


00:19:27.120 --> 00:19:28.950
working with researchers in those fields


00:19:28.960 --> 00:19:31.270
to develop new largecale simulation


00:19:31.280 --> 00:19:31.830
tools.


00:19:31.840 --> 00:19:33.750
>> The universe teaching us about the


00:19:33.760 --> 00:19:35.909
ocean. I love it. And that is your


00:19:35.919 --> 00:19:38.150
astronomy daily for Tuesday, February


00:19:38.160 --> 00:19:40.950
24th. Big day for Artemis and not in any


00:19:40.960 --> 00:19:43.110
way anyone hoped. But as we've seen


00:19:43.120 --> 00:19:45.270
today, space science never stops.


00:19:45.280 --> 00:19:47.190
Whether it's a rover finding its feet on


00:19:47.200 --> 00:19:49.750
Mars or scientists finally understanding


00:19:49.760 --> 00:19:52.070
why red giant stars change the way they


00:19:52.080 --> 00:19:53.830
do. If you want to keep up with the


00:19:53.840 --> 00:19:56.310
Aremis roll back developments, we'll


00:19:56.320 --> 00:19:58.549
have updates in tomorrow's show once


00:19:58.559 --> 00:20:01.430
