Artemis II Countdown, Auroras Over Sydney, and the Lava World That Broke the Rules
Thank you for listening to Astronomy Daily! Here's everything from today's episode: Story 1: Artemis II — T-Minus Days to Launch NASA is targeting April 1, 2026 for the launch of Artemis II — the first crewed lunar flyby since Apollo 17 in 1972. The crew of Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen will fly a 10-day free-return trajectory around the Moon aboard the Orion spacecraft on the SLS rocket from Kennedy Space Center. The six-day launch window runs April 1–6. Meanwhile, a new analysis suggests the mission could face elevated solar superflare risk, though NASA is proceeding after a successful Flight Readiness Review.

The Australian Bureau of Meteorology issued a severe storm warning for March 23. Conditions are easing on March 24 (Kp 3–4) but some aurora activity may continue. March is historically the best month for auroras due to the equinox effect, and with Solar Cycle 25 at its peak, scientists say this could be the best aurora viewing period until the mid-2030s.

TOI-561 b — an ultra-hot super-Earth about twice Earth's mass, orbiting its star every 10.56 hours — was expected to be a bare rock. Instead, JWST measured a dayside temperature far cooler than a bare rock would produce, indicating a thick atmosphere redistributing heat above a global magma ocean. The findings were published in The Astrophysical Journal Letters.

A Brown University-led team found volcanic material from the Taurus-Littrow region is strongly depleted in sulfur-33 — unlike anything found on Earth. Possible explanations include ancient lunar atmospheric chemistry or a legacy of the Theia impact that formed the Moon. Published in the Journal of Geophysical Research: Planets.

The 73rd orbital launch attempt of 2026 worldwide. Full preview: https://www.nasaspaceflight.com/2026/03/launch-preview-032326/ Update: Progress MS-33 & Spectrum Rocket Progress MS-33 (also known as Progress 94) launched from the newly-repaired Site 31/6 at Baikonur on March 22 carrying 2,509 kg of supplies for the ISS Expedition 74 crew. A KURS antenna failure required ISS commander Sergei Kud-Sverchkov to dock the vehicle manually using the TORU backup system, scheduled for 13:34 UTC on March 24. Separately, Isar Aerospace's Spectrum rocket remains on the pad at Andøya, Norway, with a new launch window on March 25 (20:00–21:00 UTC) after weather delays.

00:00:00.400 --> 00:00:02.790
Good day, stargazers, and welcome back
00:00:02.800 --> 00:00:05.349
to Astronomy Daily. I'm Anna.
00:00:05.359 --> 00:00:07.670
>> And I'm Avery. And honestly, this might
00:00:07.680 --> 00:00:09.910
be our most packed episode of the season
00:00:09.920 --> 00:00:10.950
so far.
00:00:10.960 --> 00:00:13.669
>> Between a rocket still sitting on a pad
00:00:13.679 --> 00:00:15.910
in Norway waiting for its shot at
00:00:15.920 --> 00:00:18.390
history, a cargo ship that needed a
00:00:18.400 --> 00:00:21.429
human hand on the wheel, and an entirely
00:00:21.439 --> 00:00:23.670
different kind of skyhow happening over
00:00:23.680 --> 00:00:26.230
Australian cities last night, today
00:00:26.240 --> 00:00:28.710
really has it all. Plus, fresh science
00:00:28.720 --> 00:00:30.870
off the James Webb Space Telescope that
00:00:30.880 --> 00:00:33.030
has astronomers questioning everything
00:00:33.040 --> 00:00:34.630
they thought they knew about lava
00:00:34.640 --> 00:00:37.030
worlds. We've got news about sealed moon
00:00:37.040 --> 00:00:39.030
rocks finally giving up their secrets
00:00:39.040 --> 00:00:41.270
after 50 years. And we'll walk you
00:00:41.280 --> 00:00:42.869
through one of the busiest weeks in
00:00:42.879 --> 00:00:45.670
global rocketry in recent memory. And
00:00:45.680 --> 00:00:48.229
with less than 2 weeks to go until the
00:00:48.239 --> 00:00:50.950
most historic human space flight in half
00:00:50.960 --> 00:00:54.069
a century, the countdown to Aremis 2 is
00:00:54.079 --> 00:00:56.950
well and truly on. though not everyone
00:00:56.960 --> 00:00:58.470
agrees it should be.
00:00:58.480 --> 00:00:59.990
>> There's a scientist out there saying
00:01:00.000 --> 00:01:02.630
NASA should hold off. We'll get to that.
00:01:02.640 --> 00:01:05.189
>> Without further ado, then let's dive in.
00:01:05.199 --> 00:01:06.789
>> Let's start with the big one. As of
00:01:06.799 --> 00:01:08.950
today, NASA is officially targeting
00:01:08.960 --> 00:01:11.190
April 1st. And yes, we know how that
00:01:11.200 --> 00:01:13.670
sounds. As the launch date for Artemis
00:01:13.680 --> 00:01:16.469
2, the 6-day window runs April 1st
00:01:16.479 --> 00:01:19.190
through to the 6th. And just to be clear
00:01:19.200 --> 00:01:21.670
for anyone just joining us on the show,
00:01:21.680 --> 00:01:24.630
Artemis 2 is the first time human beings
00:01:24.640 --> 00:01:26.789
will travel to the vicinity of the moon
00:01:26.799 --> 00:01:31.749
since Apollo 17 in December 1972,
00:01:31.759 --> 00:01:35.190
over 50 years. This is genuinely
00:01:35.200 --> 00:01:36.310
historic.
00:01:36.320 --> 00:01:38.069
>> Four astronauts aboard the Orion
00:01:38.079 --> 00:01:40.310
spacecraft launched on the space launch
00:01:40.320 --> 00:01:43.270
system or SLS from Kennedy Space Center
00:01:43.280 --> 00:01:45.510
in Florida. The crew is commander Reed
00:01:45.520 --> 00:01:48.069
Weisman, pilot Victor Glover, mission
00:01:48.079 --> 00:01:50.389
specialist Christina Coach, and Canadian
00:01:50.399 --> 00:01:53.270
Space Agency astronaut Jeremy Hansen.
00:01:53.280 --> 00:01:55.270
>> Victor Glover will become the first
00:01:55.280 --> 00:01:57.749
person of color to travel beyond Earth
00:01:57.759 --> 00:02:00.310
orbit. Christina Coach will be the first
00:02:00.320 --> 00:02:02.789
woman, and Jeremy Hansen will be the
00:02:02.799 --> 00:02:05.749
first non-American citizen to leave low
00:02:05.759 --> 00:02:08.790
Earth orbit. This mission is full of
00:02:08.800 --> 00:02:11.350
firsts. The crew entered quarantine at
00:02:11.360 --> 00:02:13.670
Johnson Space Center in Houston on March
00:02:13.680 --> 00:02:15.990
18th, and they traveled down to Florida
00:02:16.000 --> 00:02:18.630
on March 27th. From there, it's really
00:02:18.640 --> 00:02:20.790
just a matter of weather systems, and
00:02:20.800 --> 00:02:21.990
that launch window.
00:02:22.000 --> 00:02:24.630
>> Now, the road to get here has had its
00:02:24.640 --> 00:02:27.750
bumps. There were liquid hydrogen leaks,
00:02:27.760 --> 00:02:30.150
helium flow issue that caused a roll
00:02:30.160 --> 00:02:31.990
back to the vehicle assembly building
00:02:32.000 --> 00:02:34.390
just last month. Engineers found a
00:02:34.400 --> 00:02:36.630
blocked seal in a cable connecting the
00:02:36.640 --> 00:02:38.949
rocket to the ground systems. That's
00:02:38.959 --> 00:02:41.670
fixed now. A successful wet dress
00:02:41.680 --> 00:02:43.910
rehearsal in late February cleared the
00:02:43.920 --> 00:02:44.309
way.
00:02:44.319 --> 00:02:46.070
>> And the mission itself, once it
00:02:46.080 --> 00:02:48.630
launches, will be a 10day free return
00:02:48.640 --> 00:02:50.710
trajectory around the moon. They'll
00:02:50.720 --> 00:02:53.270
swing out to about 5,000 m beyond the
00:02:53.280 --> 00:02:55.589
lunar surface, giving the crew and the
00:02:55.599 --> 00:02:58.070
world a view of the moon that no human
00:02:58.080 --> 00:03:00.790
has had since Jean Cernin and Harrison
00:03:00.800 --> 00:03:02.550
Schmidt were there in person.
00:03:02.560 --> 00:03:04.630
>> Now, Avery, you mentioned earlier that
00:03:04.640 --> 00:03:06.470
not everyone thinks this is the right
00:03:06.480 --> 00:03:09.190
moment to go. Yeah, this is a genuinely
00:03:09.200 --> 00:03:11.350
interesting wrinkle. A researcher at
00:03:11.360 --> 00:03:13.750
Mexico's National Autonomous University,
00:03:13.760 --> 00:03:16.550
Victor Velasco Era, has published a new
00:03:16.560 --> 00:03:18.309
analysis suggesting that we are
00:03:18.319 --> 00:03:20.869
currently in a window of elevated solar
00:03:20.879 --> 00:03:23.430
superflare risk. His models point to a
00:03:23.440 --> 00:03:25.589
high activity period running from mid
00:03:25.599 --> 00:03:29.430
2025 through to mid 2026, focus on the
00:03:29.440 --> 00:03:31.350
sun's southern hemisphere. He's
00:03:31.360 --> 00:03:33.190
recommending NASA delay the mission
00:03:33.200 --> 00:03:35.030
until the second half of this year at
00:03:35.040 --> 00:03:37.589
the earliest. And you can see why he'd
00:03:37.599 --> 00:03:40.550
be concerned. We've had a G3 geomagnetic
00:03:40.560 --> 00:03:42.390
storm this week, which we're going to
00:03:42.400 --> 00:03:45.190
get to in a moment. The sun is extremely
00:03:45.200 --> 00:03:46.470
active right now.
00:03:46.480 --> 00:03:48.630
>> Right. Though NASA has assessed the
00:03:48.640 --> 00:03:50.789
risks and all teams pulled go for
00:03:50.799 --> 00:03:52.949
launch. Lorie Glaze from NASA's
00:03:52.959 --> 00:03:55.110
exploration systems directorate said,
00:03:55.120 --> 00:03:57.509
and I'm paraphrasing, that an incredible
00:03:57.519 --> 00:03:59.429
amount of work has gone into preparing
00:03:59.439 --> 00:04:01.750
for this, and they've had very open,
00:04:01.760 --> 00:04:03.509
transparent discussions about risk
00:04:03.519 --> 00:04:06.550
posture and mitigation. So, the mission
00:04:06.560 --> 00:04:09.589
is proceeding, but it does add a certain
00:04:09.599 --> 00:04:12.070
tension to an already extraordinary
00:04:12.080 --> 00:04:14.550
story, doesn't it? The sun is at the
00:04:14.560 --> 00:04:17.189
peak of its 11-year cycle. We're heading
00:04:17.199 --> 00:04:19.430
back to the moon, and a scientist is
00:04:19.440 --> 00:04:21.670
saying, "Are you sure you want to do
00:04:21.680 --> 00:04:22.710
this now?"
00:04:22.720 --> 00:04:25.590
>> Humanity doing bold things anyway. Feels
00:04:25.600 --> 00:04:28.150
on brand, honestly.
00:04:28.160 --> 00:04:29.909
>> We'll have everything you need to watch
00:04:29.919 --> 00:04:32.070
the launch live in our show notes.
00:04:32.080 --> 00:04:34.870
Fingers crossed for April the 1st. Okay,
00:04:34.880 --> 00:04:36.950
so speaking of the sun, let's talk about
00:04:36.960 --> 00:04:38.950
what it's been doing to our skies this
00:04:38.960 --> 00:04:41.909
week because it has been spectacular.
00:04:41.919 --> 00:04:44.790
>> A series of coronal mass ejections or
00:04:44.800 --> 00:04:48.310
CMEs that left the sun on March 16th and
00:04:48.320 --> 00:04:51.270
18th arrived at Earth around the equinox
00:04:51.280 --> 00:04:53.830
and they drove geomagnetic storming to
00:04:53.840 --> 00:04:56.550
G3 levels on the Noah scale. That's
00:04:56.560 --> 00:04:58.469
classified as strong.
00:04:58.479 --> 00:05:00.870
>> And the result were auroras visible from
00:05:00.880 --> 00:05:03.350
an extraordinary range of latitudes.
00:05:03.360 --> 00:05:05.430
We're talking reports of vivid displays
00:05:05.440 --> 00:05:08.629
from New York, London, Northern France,
00:05:08.639 --> 00:05:11.189
even parts of Scotland lit up. And when
00:05:11.199 --> 00:05:13.270
you see aurora reports from Scotland,
00:05:13.280 --> 00:05:14.950
you're already dealing with something
00:05:14.960 --> 00:05:15.909
significant.
00:05:15.919 --> 00:05:18.310
>> But the story closest to home for many
00:05:18.320 --> 00:05:21.430
of our listeners. The Aurora Arales was
00:05:21.440 --> 00:05:23.990
visible across major Australian cities
00:05:24.000 --> 00:05:26.469
last night. The Australian Bureau of
00:05:26.479 --> 00:05:29.670
Meteorology issued a severe geomagnetic
00:05:29.680 --> 00:05:31.909
storm warning and the southern lights
00:05:31.919 --> 00:05:34.230
were reported from Melbourne, Sydney,
00:05:34.240 --> 00:05:35.990
Brisbane, and Adelaide.
00:05:36.000 --> 00:05:38.710
>> That is remarkable. Sydney is not what
00:05:38.720 --> 00:05:40.629
you'd call a typical aurora viewing
00:05:40.639 --> 00:05:42.950
destination. If you were outside last
00:05:42.960 --> 00:05:44.950
night and happened to look south,
00:05:44.960 --> 00:05:46.710
especially from somewhere with a clear
00:05:46.720 --> 00:05:49.270
horizon, you may well have caught it.
00:05:49.280 --> 00:05:52.150
>> As of today, March 24th, conditions are
00:05:52.160 --> 00:05:55.350
easing. We're dropping back to KP 3 to
00:05:55.360 --> 00:05:58.469
4, unsettled to active with a slight
00:05:58.479 --> 00:06:01.189
chance of isolated G1 minor storm
00:06:01.199 --> 00:06:03.749
intervals. So, there may still be some
00:06:03.759 --> 00:06:06.070
activity tonight, but the peak has
00:06:06.080 --> 00:06:06.950
passed.
00:06:06.960 --> 00:06:09.189
>> Now, why is March such a good month for
00:06:09.199 --> 00:06:11.110
auroras? This is something a lot of
00:06:11.120 --> 00:06:12.390
people don't know.
00:06:12.400 --> 00:06:14.870
>> It's called the equinox effect. Around
00:06:14.880 --> 00:06:17.350
the March and September equinoxes, the
00:06:17.360 --> 00:06:19.510
geometry of Earth's magnetic field
00:06:19.520 --> 00:06:21.749
relative to the solar wind becomes
00:06:21.759 --> 00:06:24.469
particularly favorable. The field lines
00:06:24.479 --> 00:06:26.629
are better aligned to allow charged
00:06:26.639 --> 00:06:28.710
particles in, which means you can get
00:06:28.720 --> 00:06:31.270
strong auroral activity even from
00:06:31.280 --> 00:06:33.830
moderate solar events. Combined with the
00:06:33.840 --> 00:06:36.230
current solar maximum, the peak of solar
00:06:36.240 --> 00:06:38.790
cycle 25, and we're living through what
00:06:38.800 --> 00:06:40.950
could genuinely be the best aurora
00:06:40.960 --> 00:06:44.309
viewing period until the mid 2030s. So,
00:06:44.319 --> 00:06:45.909
if you've been meaning to chase the
00:06:45.919 --> 00:06:48.390
lights, the message from scientists is
00:06:48.400 --> 00:06:50.950
this is your window. The sun will start
00:06:50.960 --> 00:06:52.870
winding down from here, and the next
00:06:52.880 --> 00:06:55.749
solar maximum is over a decade away.
00:06:55.759 --> 00:06:57.990
>> We'll have Aurora forecast links in the
00:06:58.000 --> 00:06:59.830
show notes so you can track what tonight
00:06:59.840 --> 00:07:01.749
looks like from your location.
00:07:01.759 --> 00:07:03.589
>> I'm sure our producer, who lives in
00:07:03.599 --> 00:07:06.790
Sydney, will be out and looking up. Now,
00:07:06.800 --> 00:07:09.749
let's head into deep space and into one
00:07:09.759 --> 00:07:12.230
of the most genuinely surprising pieces
00:07:12.240 --> 00:07:14.469
of planetary science we've seen in a
00:07:14.479 --> 00:07:17.830
while. James Webb has done it again.
00:07:17.840 --> 00:07:19.830
>> I love a story where the headline is
00:07:19.840 --> 00:07:21.909
basically, "Scientists found something
00:07:21.919 --> 00:07:23.909
they were almost certain couldn't be
00:07:23.919 --> 00:07:24.710
there."
00:07:24.720 --> 00:07:28.390
>> So, the planet in question is called toi
00:07:28.400 --> 00:07:30.070
561b.
00:07:30.080 --> 00:07:32.469
It's a super Earth about twice the mass
00:07:32.479 --> 00:07:36.150
of our planet orbiting a star around 280
00:07:36.160 --> 00:07:39.029
lighty years away. And when we say close
00:07:39.039 --> 00:07:42.309
to its star, we mean absurdly, almost
00:07:42.319 --> 00:07:44.790
comically close. It completes a full
00:07:44.800 --> 00:07:48.710
orbit in just 10.56 hours. A year on
00:07:48.720 --> 00:07:50.629
this world is shorter than the average
00:07:50.639 --> 00:07:51.589
working day.
00:07:51.599 --> 00:07:54.550
>> It orbits at 140th the distance that
00:07:54.560 --> 00:07:57.430
Mercury sits from our sun. The dayside
00:07:57.440 --> 00:08:00.550
is in permanent unrelenting sunlight.
00:08:00.560 --> 00:08:03.589
The planet is likely tidily locked. Same
00:08:03.599 --> 00:08:06.790
face always towards the star. Same face
00:08:06.800 --> 00:08:09.270
always in darkness. The surface is
00:08:09.280 --> 00:08:11.670
thought to be a global ocean of molten
00:08:11.680 --> 00:08:14.390
rock. And under those conditions,
00:08:14.400 --> 00:08:17.830
extreme radiation, extreme heat, extreme
00:08:17.840 --> 00:08:20.309
proximity to the star, the scientific
00:08:20.319 --> 00:08:22.710
consensus was that any atmosphere this
00:08:22.720 --> 00:08:24.710
planet might have once had would have
00:08:24.720 --> 00:08:27.270
been stripped away long ago. It should
00:08:27.280 --> 00:08:31.830
be a bare airless rock. Except it isn't.
00:08:31.840 --> 00:08:34.389
The Carnegie Institution's le team used
00:08:34.399 --> 00:08:37.029
Web's near infrared spectroscope,
00:08:37.039 --> 00:08:39.110
Nearspec, to take the planet's
00:08:39.120 --> 00:08:41.110
temperature by measuring how much light
00:08:41.120 --> 00:08:44.870
the system emitted when TOI561B
00:08:44.880 --> 00:08:47.670
passed behind its star. If it were a
00:08:47.680 --> 00:08:49.990
bare rock, the dayside should reach
00:08:50.000 --> 00:08:52.710
something close to 4,900°
00:08:52.720 --> 00:08:57.350
F, around 2700 C. Instead, they measured
00:08:57.360 --> 00:09:02.790
around 3,200° F or 1,800 C. Still
00:09:02.800 --> 00:09:05.430
extraordinarily hot, but significantly
00:09:05.440 --> 00:09:07.509
cooler than expected. And the only
00:09:07.519 --> 00:09:09.430
explanation that fits the data is that
00:09:09.440 --> 00:09:11.269
there's an atmosphere up there,
00:09:11.279 --> 00:09:13.509
redistributing heat from the dayside to
00:09:13.519 --> 00:09:14.710
the night side.
00:09:14.720 --> 00:09:17.269
>> The lead researcher, Johanna Tesca at
00:09:17.279 --> 00:09:19.590
Carnegie Science, described the planet
00:09:19.600 --> 00:09:22.310
as, and this is a direct quote, really
00:09:22.320 --> 00:09:25.269
like a wet lava ball. The idea is that
00:09:25.279 --> 00:09:27.269
there's a feedback loop happening.
00:09:27.279 --> 00:09:29.590
Volatile gases bubble up from the magma
00:09:29.600 --> 00:09:31.590
ocean into the atmosphere while the
00:09:31.600 --> 00:09:34.070
magma ocean simultaneously pulls some
00:09:34.080 --> 00:09:36.389
gases back in. It's a strange
00:09:36.399 --> 00:09:38.389
equilibrium. What makes this
00:09:38.399 --> 00:09:40.310
scientifically significant beyond the
00:09:40.320 --> 00:09:42.550
wow factor is what it tells us about
00:09:42.560 --> 00:09:45.110
rocky planet evolution. We've assumed
00:09:45.120 --> 00:09:47.430
for a long time that small, hot,
00:09:47.440 --> 00:09:50.389
close-in worlds can't hold atmospheres.
00:09:50.399 --> 00:09:53.990
POI 561B suggests the reality is more
00:09:54.000 --> 00:09:56.070
complicated and potentially more
00:09:56.080 --> 00:09:57.110
interesting.
00:09:57.120 --> 00:09:59.269
>> The team is now analyzing the full data
00:09:59.279 --> 00:10:01.269
set to map temperature patterns all the
00:10:01.279 --> 00:10:03.110
way around the planet and try to narrow
00:10:03.120 --> 00:10:04.870
down what the atmosphere is actually
00:10:04.880 --> 00:10:07.910
made of. Water vapor, carbon dioxide,
00:10:07.920 --> 00:10:10.630
silicate clouds, all on the table.
00:10:10.640 --> 00:10:13.750
>> One of JWST's core missions is finding
00:10:13.760 --> 00:10:16.150
atmospheres around rocky worlds. Because
00:10:16.160 --> 00:10:18.550
as far as we know, an atmosphere is a
00:10:18.560 --> 00:10:22.389
prerequisite for life. POI 561b is
00:10:22.399 --> 00:10:24.310
certainly not habitable in any
00:10:24.320 --> 00:10:26.470
conventional sense. But understanding
00:10:26.480 --> 00:10:28.870
how a world this extreme holds onto its
00:10:28.880 --> 00:10:31.030
air could tell us a great deal about
00:10:31.040 --> 00:10:33.350
rocky planets that are far more
00:10:33.360 --> 00:10:35.829
temperate. There's something genuinely
00:10:35.839 --> 00:10:38.470
poetic about today's next story. We're
00:10:38.480 --> 00:10:41.670
going back to December 1972, the last
00:10:41.680 --> 00:10:43.829
time humans walked on the moon, and
00:10:43.839 --> 00:10:45.269
discovering that some of what they
00:10:45.279 --> 00:10:47.910
brought home has been quietly waiting 50
00:10:47.920 --> 00:10:50.550
years to tell us something unexpected.
00:10:50.560 --> 00:10:52.710
>> The Apollo Next Generation Sample
00:10:52.720 --> 00:10:55.509
Analysis Program, or ANXA, was set up
00:10:55.519 --> 00:10:57.670
specifically for this purpose. When the
00:10:57.680 --> 00:10:59.509
Apollo astronauts returned from the
00:10:59.519 --> 00:11:01.910
moon, NASA deliberately sealed some of
00:11:01.920 --> 00:11:04.069
the samples and set them aside, knowing
00:11:04.079 --> 00:11:06.230
that future scientists with better tools
00:11:06.240 --> 00:11:08.470
would be able to extract more from them
00:11:08.480 --> 00:11:10.949
than the technology of the 1970s ever
00:11:10.959 --> 00:11:11.750
could.
00:11:11.760 --> 00:11:13.910
>> And that moment has now arrived for a
00:11:13.920 --> 00:11:15.990
double drive tube pushed into the lunar
00:11:16.000 --> 00:11:18.550
surface at the Taurus litau region by
00:11:18.560 --> 00:11:20.870
Jean Cernin and Harrison Schmidt during
00:11:20.880 --> 00:11:24.470
Apollo 17. A team led by James Den at
00:11:24.480 --> 00:11:27.030
Brown University used a technique called
00:11:27.040 --> 00:11:29.590
secondary ion mass spectrometry to
00:11:29.600 --> 00:11:31.990
measure sulfur isotopes. And what they
00:11:32.000 --> 00:11:34.470
found was not what anyone expected.
00:11:34.480 --> 00:11:36.870
>> So for context, Earth and the moon have
00:11:36.880 --> 00:11:39.190
remarkably similar oxygen isotope
00:11:39.200 --> 00:11:41.590
signatures. Scientists have long assumed
00:11:41.600 --> 00:11:43.269
that sulfur would follow the same
00:11:43.279 --> 00:11:45.590
pattern, that the moon's interior would
00:11:45.600 --> 00:11:47.590
look chemically similar to Earth's in
00:11:47.600 --> 00:11:50.150
this regard. Dotton's team expected to
00:11:50.160 --> 00:11:51.990
confirm that assumption.
00:11:52.000 --> 00:11:54.389
>> Instead, the volcanic material in the
00:11:54.399 --> 00:11:56.870
sample is strongly depleted in sulfur
00:11:56.880 --> 00:12:00.389
33, one of four stable sulfur isotopes.
00:12:00.399 --> 00:12:03.110
The values are, in Dotton's own words,
00:12:03.120 --> 00:12:05.030
very different from anything we find on
00:12:05.040 --> 00:12:07.030
Earth. He said he simply wasn't
00:12:07.040 --> 00:12:08.310
expecting that.
00:12:08.320 --> 00:12:10.389
>> So, what does it mean? There are two
00:12:10.399 --> 00:12:12.710
leading explanations and neither is
00:12:12.720 --> 00:12:14.870
boring. The first is that this is
00:12:14.880 --> 00:12:17.430
evidence of very ancient chemistry.
00:12:17.440 --> 00:12:19.590
sulfur that interacted with ultraviolet
00:12:19.600 --> 00:12:22.389
light in an early thin lunar atmosphere
00:12:22.399 --> 00:12:24.710
billions of years ago. The implication
00:12:24.720 --> 00:12:26.790
there would be that material somehow
00:12:26.800 --> 00:12:29.110
cycled from the lunar surface into the
00:12:29.120 --> 00:12:32.069
mantle, a kind of protoplate tectonics
00:12:32.079 --> 00:12:34.230
on a world we don't think has ever had
00:12:34.240 --> 00:12:35.670
plate tectonics.
00:12:35.680 --> 00:12:37.750
>> The second explanation reaches even
00:12:37.760 --> 00:12:39.829
further back. The leading theory of the
00:12:39.839 --> 00:12:42.230
moon's origin is the giant impact. A
00:12:42.240 --> 00:12:44.470
Mars-sized body called Thea collided
00:12:44.480 --> 00:12:46.629
with the early Earth, and the debris
00:12:46.639 --> 00:12:49.190
eventually coalesed into the moon. If
00:12:49.200 --> 00:12:51.030
Thea had a very different sulfur
00:12:51.040 --> 00:12:53.190
composition from Earth, that signature
00:12:53.200 --> 00:12:54.949
might still be locked inside the lunar
00:12:54.959 --> 00:12:57.190
mantle today. A fingerprint from a
00:12:57.200 --> 00:12:59.910
collision that happened 4 billion years
00:12:59.920 --> 00:13:00.710
ago.
00:13:00.720 --> 00:13:03.110
>> The data doesn't currently favor one
00:13:03.120 --> 00:13:05.590
explanation over the other. Dottton is
00:13:05.600 --> 00:13:07.350
hoping that comparisons with samples
00:13:07.360 --> 00:13:09.590
from Mars and other planetary bodies
00:13:09.600 --> 00:13:11.750
will help resolve it. But the broader
00:13:11.760 --> 00:13:14.150
message is clear. These samples are
00:13:14.160 --> 00:13:17.269
still yielding genuine surprises decades
00:13:17.279 --> 00:13:19.350
after they were collected. And there are
00:13:19.360 --> 00:13:21.750
more sealed Apollo containers still to
00:13:21.760 --> 00:13:22.790
be opened.
00:13:22.800 --> 00:13:24.550
>> There is something remarkable about the
00:13:24.560 --> 00:13:26.310
fact that astronauts who have been gone
00:13:26.320 --> 00:13:29.110
for over 50 years are still in a very
00:13:29.120 --> 00:13:31.030
real sense contributing to our
00:13:31.040 --> 00:13:33.269
understanding of the solar system. All
00:13:33.279 --> 00:13:35.670
right, let's do a lap of the launchpads
00:13:35.680 --> 00:13:37.590
because this week is genuinely
00:13:37.600 --> 00:13:39.190
exceptional for space activity
00:13:39.200 --> 00:13:42.150
worldwide. NASA spaceflight.com
00:13:42.160 --> 00:13:44.230
published their weekly preview and
00:13:44.240 --> 00:13:46.389
honestly it reads like a greatest hits
00:13:46.399 --> 00:13:48.629
of the current space age. Let's start
00:13:48.639 --> 00:13:51.110
with what's already happened. SpaceX
00:13:51.120 --> 00:13:52.790
kicked off the week with the Falcon 9
00:13:52.800 --> 00:13:54.710
launch from Vandenberg in California
00:13:54.720 --> 00:13:57.590
today, Tuesday, carrying 25 Starling
00:13:57.600 --> 00:13:59.910
satellites to sun-synchronous orbit.
00:13:59.920 --> 00:14:03.990
Booster B1081 flying for the 23rd time.
00:14:04.000 --> 00:14:05.670
Routine at this point, but still
00:14:05.680 --> 00:14:07.670
remarkable when you say it out loud.
00:14:07.680 --> 00:14:09.910
>> Tomorrow, Wednesday, is arguably the
00:14:09.920 --> 00:14:12.389
biggest single day in the schedule. ESAR
00:14:12.399 --> 00:14:14.470
Aerospace's Spectrum rocket has its
00:14:14.480 --> 00:14:17.509
window at 8:00 p.m. UTC from Endoa in
00:14:17.519 --> 00:14:19.350
Norway. We'll talk about that more in
00:14:19.360 --> 00:14:22.389
the update segment. And at 9:14 a.m.
00:14:22.399 --> 00:14:25.430
UTC, Rocket Labs Electron launches from
00:14:25.440 --> 00:14:28.069
New Zealand's Mahia Peninsula, carrying
00:14:28.079 --> 00:14:30.949
two ESA Celeste satellites. Those are
00:14:30.959 --> 00:14:33.030
the first of 10 planned navigation
00:14:33.040 --> 00:14:35.189
demonstration satellites that will test
00:14:35.199 --> 00:14:37.189
positioning technology in low Earth
00:14:37.199 --> 00:14:37.910
orbit.
00:14:37.920 --> 00:14:40.629
>> Also Wednesday, China launches a Chang
00:14:40.639 --> 00:14:44.550
Zang 2C from Taiwan, payload classified,
00:14:44.560 --> 00:14:47.350
which will be that rocket's 87th mission
00:14:47.360 --> 00:14:51.430
overall. The CZ2C has been flying since
00:14:51.440 --> 00:14:52.949
1982,
00:14:52.959 --> 00:14:54.389
which puts it in some pretty
00:14:54.399 --> 00:14:55.750
distinguished company.
00:14:55.760 --> 00:14:58.069
>> Thursday brings another Falcon 9 from
00:14:58.079 --> 00:15:00.629
Cape Canaveral carrying 29 Starling
00:15:00.639 --> 00:15:02.790
satellites. And this one has a record
00:15:02.800 --> 00:15:06.310
attached. Booster B1067 will be making
00:15:06.320 --> 00:15:09.030
its 34th flight, setting a new record
00:15:09.040 --> 00:15:11.910
for Falcon 9 booster reuse. This rocket
00:15:11.920 --> 00:15:14.870
first flew in June 2021 on a cargo
00:15:14.880 --> 00:15:16.710
resupply mission to the International
00:15:16.720 --> 00:15:19.110
Space Station. It's now flying for the
00:15:19.120 --> 00:15:22.389
34th time. SpaceX has fundamentally
00:15:22.399 --> 00:15:24.870
changed what reusability means.
00:15:24.880 --> 00:15:27.350
>> Friday is enormous. China's commercial
00:15:27.360 --> 00:15:29.670
launch company CAS Space flies its
00:15:29.680 --> 00:15:32.470
Kinetic 1 solid rocket from Juan with an
00:15:32.480 --> 00:15:35.030
undisclosed payload. And Rosscosmos
00:15:35.040 --> 00:15:36.949
launches the first ever flight of the
00:15:36.959 --> 00:15:39.990
Soyuse 5 rocket from Biconor, also
00:15:40.000 --> 00:15:42.790
called. This rocket is Russia's long-
00:15:42.800 --> 00:15:45.110
aaited replacement for the Zenit family.
00:15:45.120 --> 00:15:46.949
It carries a mass simulator on this
00:15:46.959 --> 00:15:49.189
debut flight, launching from a pad that
00:15:49.199 --> 00:15:51.269
hasn't seen an orbital launch since
00:15:51.279 --> 00:15:54.069
2017. Big moment for Russian launch
00:15:54.079 --> 00:15:55.430
vehicle development.
00:15:55.440 --> 00:15:57.910
>> And the week closes out on Sunday with
00:15:57.920 --> 00:16:01.910
two more. ULA's Atlas V5 launching 29
00:16:01.920 --> 00:16:03.670
Amazon LEO satellites from Cape
00:16:03.680 --> 00:16:06.470
Canaveral in its powerful 551
00:16:06.480 --> 00:16:08.870
configuration. That's five solid rocket
00:16:08.880 --> 00:16:11.350
boosters for what will be that rocket's
00:16:11.360 --> 00:16:14.629
107th overall mission. And SpaceX wraps
00:16:14.639 --> 00:16:17.269
things up with Transporter 16, a ride
00:16:17.279 --> 00:16:19.430
share mission from Vandenberg carrying
00:16:19.440 --> 00:16:21.910
dozens of small satellites. That will be
00:16:21.920 --> 00:16:25.590
SpaceX's 40th Falcon 9 launch of 2026
00:16:25.600 --> 00:16:28.310
alone and the 73rd orbital launch
00:16:28.320 --> 00:16:31.670
attempt worldwide this year. So, five
00:16:31.680 --> 00:16:34.470
countries, six different rockets, Falcon
00:16:34.480 --> 00:16:39.030
9, Electron, Spectrum, CZ2C, Kinetica 1,
00:16:39.040 --> 00:16:42.389
Soyuse 5, Atlas V5, launching from
00:16:42.399 --> 00:16:44.629
California, Florida, New Zealand,
00:16:44.639 --> 00:16:46.870
Norway, two sites in China, and
00:16:46.880 --> 00:16:49.670
Kazakhstan in one week.
00:16:49.680 --> 00:16:52.790
>> The age of routine space flight is here.
00:16:52.800 --> 00:16:54.710
It's just also occasionally
00:16:54.720 --> 00:16:57.189
extraordinary. Before we wrap, a quick
00:16:57.199 --> 00:16:58.870
followup on two stories we covered
00:16:58.880 --> 00:17:00.550
yesterday because both have had
00:17:00.560 --> 00:17:02.790
developments today. Let's start with the
00:17:02.800 --> 00:17:05.189
ISS. You'll remember that Russia
00:17:05.199 --> 00:17:08.549
launched the Progress MS33 cargo ship,
00:17:08.559 --> 00:17:11.829
also called Progress 94 on Sunday from
00:17:11.839 --> 00:17:14.789
the Biconor Cosmodrome, carrying about 2
00:17:14.799 --> 00:17:17.829
and 1/2 tons of supplies for the 7person
00:17:17.839 --> 00:17:22.069
Expedition 74 crew. Food, fuel, water,
00:17:22.079 --> 00:17:24.870
oxygen, the good stuff. But there was a
00:17:24.880 --> 00:17:27.189
complication. Shortly after launch, one
00:17:27.199 --> 00:17:29.430
of the spacecraft's two KURS automated
00:17:29.440 --> 00:17:31.830
docking antennas failed to deploy. The
00:17:31.840 --> 00:17:34.150
KUR system is the normal hands-off
00:17:34.160 --> 00:17:37.110
approach. The ship guides itself in with
00:17:37.120 --> 00:17:38.710
only one antenna working. Full
00:17:38.720 --> 00:17:40.630
automation wasn't available.
00:17:40.640 --> 00:17:43.590
>> So this morning, ISS Commander Sergey
00:17:43.600 --> 00:17:47.669
Kudkov took over manually using the Tou
00:17:47.679 --> 00:17:49.830
system. That's the Telerobotically
00:17:49.840 --> 00:17:52.310
operated rendevous system, a control
00:17:52.320 --> 00:17:55.190
panel inside the Zvezda service module.
00:17:55.200 --> 00:17:58.070
The spacecraft flew itself to within 200
00:17:58.080 --> 00:18:00.710
m of the station and from there Cuds
00:18:00.720 --> 00:18:03.270
Ferkov guided it in. Docking was
00:18:03.280 --> 00:18:06.390
scheduled for 9:34 Eastern time. Ross
00:18:06.400 --> 00:18:07.990
Cosmos were quick to point out that
00:18:08.000 --> 00:18:09.990
manual approaches are routinely
00:18:10.000 --> 00:18:12.310
practiced during Cosmo training. This
00:18:12.320 --> 00:18:14.630
was a contingency, not a crisis. And
00:18:14.640 --> 00:18:16.310
there's a second layer to the story
00:18:16.320 --> 00:18:18.710
worth noting. This was the first launch
00:18:18.720 --> 00:18:21.510
from site 31 at Biconor since that pad
00:18:21.520 --> 00:18:23.990
was damaged during the Soyuse MS28
00:18:24.000 --> 00:18:26.230
launch last November when part of the
00:18:26.240 --> 00:18:28.549
launch infrastructure collapsed. That
00:18:28.559 --> 00:18:30.710
pad is Russia's only one capable of
00:18:30.720 --> 00:18:32.710
sending crude missions and cargo ships
00:18:32.720 --> 00:18:35.669
to the ISS. Its return to service is
00:18:35.679 --> 00:18:37.270
genuinely significant.
00:18:37.280 --> 00:18:39.750
>> We'll keep watching and with any luck,
00:18:39.760 --> 00:18:42.390
Progress 94 is safely birthed at the
00:18:42.400 --> 00:18:45.110
Pois module as you listen to this. And
00:18:45.120 --> 00:18:47.430
on the other story we promised to follow
00:18:47.440 --> 00:18:49.830
Isar Aerospace's Spectrum rocket is
00:18:49.840 --> 00:18:52.549
still on the pad. Weather Andoya pushed
00:18:52.559 --> 00:18:54.230
the attempt from Sunday then from
00:18:54.240 --> 00:18:56.310
yesterday. The current window is
00:18:56.320 --> 00:18:58.710
Wednesday night 8:00 p.m. to 900 p.m.
00:18:58.720 --> 00:19:01.110
UTC. We'll have an update in tomorrow's
00:19:01.120 --> 00:19:01.750
episode.
00:19:01.760 --> 00:19:03.909
>> If it succeeds, it will be the first
00:19:03.919 --> 00:19:06.310
time a rocket designed, built, and
00:19:06.320 --> 00:19:08.710
launched from continental European soil
00:19:08.720 --> 00:19:11.590
has reached orbit. That is a headline we
00:19:11.600 --> 00:19:13.590
very much want to be able to read.
00:19:13.600 --> 00:19:15.669
Fingers crossed for ISAR and the whole
00:19:15.679 --> 00:19:17.510
European space industry.
00:19:17.520 --> 00:19:19.430
>> Again, we'll update any new developments
00:19:19.440 --> 00:19:20.789
in tomorrow's show.
00:19:20.799 --> 00:19:22.870
>> That is your Astronomy Daily for
00:19:22.880 --> 00:19:25.830
Tuesday, March 24th. We've got a lot of
00:19:25.840 --> 00:19:28.310
threads in the air right now. Artemis 2
00:19:28.320 --> 00:19:30.789
approaching its launch window. Spectrum
00:19:30.799 --> 00:19:32.870
waiting for the weather. A sun that
00:19:32.880 --> 00:19:35.110
doesn't want to sit still. So, it's a
00:19:35.120 --> 00:19:36.549
great time to make sure you're
00:19:36.559 --> 00:19:38.150
