China Aces Lunar Abort Test, Viking Life Debate Reignited, and Hubble's Dying Star

Hey, it's Cole Swindale.

After I give everything I've got to land a perfect vocal, I usually take five before

jumping into the next track.

And I've learned exactly how to recharge in that time.

Some folks grab coffee, I hit a quick good lookspin.

Next thing you know, the break is just as fun as land down the track.

A better break makes for a better take.

Need a break?

Let's chumble.

Good day and welcome to Astronomy Daily.

Your go to source for everything happening in space and astronomy.

I'm Anna and I'm Avery.

It's Thursday, February the 12th, 2026 and we have a packed show for you today.

We really do.

China has just pulled off a major milestone in its push to land astronauts on the moon,

including a pretty spectacular rocket splashdown that should have a few people at SpaceX

paying attention.

We've also got ULA's Vulcan Centaur rocket launching a pair of space surveillance satellites

for the US Space Force.

A deep dive into why Artemis 2 has so few chances to actually get off the ground and a stunning

new Hubble image of a dying star.

Plus, did NASA's Viking missions actually find life on Mars 50 years ago?

New research says the answer might be yes and astronomers are still hunting for the

remains of a comet that dramatically fell apart during COVID lockdowns.

Let's get into it.

Our lead story today takes us to Wang Chong Space Launch site on the island of Hainan,

where yesterday, February 11th, China conducted a landmark test that checked off multiple

firsts in a single mission.

This was a low altitude demonstration flight of China's next generation Long March 10 rocket,

firing the Mangzhou crew capsule, and what they were testing was something called a Max-Q

abort.

Basically, can the capsule safely escape the rocket at the moment of maximum aerodynamic

stress during a cent?

And for context, that's the point during any rocket launch where the vehicle is experiencing

the greatest combination of speed and atmospheric resistance.

If something goes wrong at Max-Q, the crew needs to get away fast.

This was China's first ever test of that scenario with a crude class spacecraft.

The capsule successfully separated from the rocket, deployed its parachutes, and was recovered

at sea.

It was carrying lunar space suits and test dummies rather than actual tyco knots, obviously,

but the abort system performed exactly as designed.

Now, here is where it gets really interesting, Avery.

After the capsule separated, the Long March 10 first stage didn't just tumble into the

ocean.

It performed a powered vertical landing, a soft splash down at sea, very much in the

style of SpaceX's Falcon 9 booster recoveries.

And that's a huge deal because, until now, only the United States has had operational

reusable orbital-class rockets.

This was China's first successful rocket recovery attempt, and it worked on the very first

powered flight of the Long March 10 prototype.

And they even had a dedicated autonomous recovery vessel, called the Ling Hang Zer, standing

by, which is essentially China's answer to SpaceX's drone ships.

The full Long March 10 is going to be an absolute beast when it's complete, a tricor rocket

standing around 90 meters tall with about 2,700 tons of lift-off thrust.

It's designed to be China's largest launch vehicle, and the only one capable of sending

both a cruise spacecraft and a lunar lander to the moon in a single launch.

If things continue at this pace, China is projecting a full orbital flight of the Long March

10 by 2027, with tyconauts on the lunar surface before the end of the decade.

That puts them in a very real race with NASA's Artemis program, which is targeting its

own crude landing with Artemis III no earlier than 2028.

This test was conducted from the brand new launch pad number three in Wangchang, which

was built specifically for these lunar missions, so the infrastructure is going in alongside

the hardware.

A genuinely significant day for the Chinese space program, and one that adds real momentum

to what's shaping up to be the most exciting moon race since Apollo.

Dicking with rockets, but moving to Cape Cammabral, ULA's Vulcan Centaur rocket is set

to launch early this morning, February 12, with the window opening at 3.30 a.m. Eastern

time.

This is the fourth Vulcan mission overall, and the first of 2026.

The payload is a pair of GSSAP satellites.

That's the Geosynchronous Space Situational Awareness program, built by Northrop Grumman

for the U.S. Space Force.

Think of GSSAP as a neighborhood watch program for Geosynchronous orbit.

These satellites monitor other spacecraft at that critical 35,000 kilometer altitude, improving

flight safety, and giving Space Force operators better situational awareness about what's

happening up there.

There's also a secondary payload called propulsive ESPA, essentially a training spacecraft

that Space Force Guardians will use to practice precision orbital maneuvers, and validate

techniques for protecting assets and orbit.

What's notable about this particular mission is that it's the longest Vulcan flight to

date, nearly 10 hours, because the Centaur upper stage is performing a direct insertion

all the way to Geosynchronous orbit, rather than just dropping the satellites into a transfer

orbit.

ULA is under some pressure this year.

They've got in-term CEO John Elban at the helm after Tori Bruno departed to join Blue

Origin late last year, and they're targeting 18 to 22 launches in 2026, after falling

short of their targets in 2025.

They've invested heavily in infrastructure, a second mobile launch platform, and a second

integration facility at the Cape.

So the capacity is there.

The question is whether Vulcan can deliver on the reliability and cadence that their roughly

80 mission backlog demands.

We should note that ULA's webcast coverage will end at faring separation, about five

minutes after launch, because the classified nature of the payload means the rest of the

mission is conducted in silence.

Now, speaking of getting rockets off the ground, let's talk about Artemis II, because

if you've been following the countdown to the first crude moon mission in over 50 years,

you might have noticed something surprising about how few chances there actually are

to launch.

NASA has published the available launch dates, and there are just 11 opportunities across

March and April combined.

Five dates in March, the six through the ninth, plus March 11th, and six in April.

Each window is about two hours long.

11 chances in 61 days.

That's it, and some of those could be lost to weather or the need to replace consumables

like rocket fuel, so why so few?

It all comes down to orbital mechanics and the specific requirements of this mission.

Artemis II doesn't fly straight to the moon.

The SLS rocket first delivers the Orion capsule to high-earth orbit, where the crew and

ground teams run through a series of checkouts.

Then comes a Transluner injection burn to send Orion on its way.

So, the launch time on any given day has to thread the needle.

SLS needs to reach the right orbit.

Orion needs to be in the correct alignment with both Earth and the moon for that Transluner

injection burn, and the whole trajectory has to work as a free return loop using the

moon's gravity to sling the capsule home.

And then there's a power constraint.

Orion's solar arrays can't be in darkness for more than 90 minutes at a stretch, so NASA

has to rule out any trajectory that would put the spacecraft in an extended eclipse.

That alone eliminates a lot of potential dates.

The return profile matters, too.

Orion needs a specific entry angle and conditions for splashdown, so that further narrows the

field.

Now, the reason we're talking about March and April specifically is that the first wet

dress rehearsal, that's the full practice run of fueling and countdown procedures, ended

early on February 2nd, because of a liquid hydrogen leak.

That took February off the table entirely.

A second wet dress attempt is expected soon, possibly this weekend, and NASA officials

have been reassuring everyone that there are launch opportunities in every month beyond

April as well.

They just haven't published those dates yet.

And it's worth remembering that Artemis I had similar hydrogen leak issues and still flew

successfully in late 2022, so this isn't uncharted territory.

Whenever it flies, it'll be historic.

No astronaut has been beyond low-earth orbit since Apollo 17 in December 1972.

That's over 53 years.

Moving on to our next story, and it's time for some pure cosmic beauty, NASA has released

a breathtaking new image from the Hubble Space Telescope showing the egg nebula in extraordinary

detail.

The egg nebula is about a thousand light years away in the constellation's sickness, and

it's what astronomers call a pre-planetary nebula, which despite the name has nothing

to do with planets forming.

It's the early stage of a dying sun-like star, shedding its outer layers.

And NASA describes it as the first, youngest, and closest pre-planetary nebula ever discovered,

which makes it incredibly valuable for studying how stars like our sun eventually meet their

end.

What makes this image so striking is the structure.

At the center, you have the dying star, the yoke of the egg, hidden behind a dense cloud

of dust.

Quinn beams of light punch outward through gaps in that dusty shell, illuminating a series

of concentric arcs of gas that ripple outward like waves.

And unlike most nebulae, which glow because their gas has been ionized, the egg nebula

shines purely by reflected light from the central star.

The star hasn't heated up enough yet to ionize its surroundings.

That's what makes this a pre-planetary nebula rather than a full planetary nebula.

The symmetry is remarkable, too.

Scientists say the patterns are far too orderly to have come from a violent event like a

supernova.

Instead, they point to coordinated sputtering events in the carbon-enriched core of the

dying star, though the exact mechanism is still poorly understood.

There's also evidence of gravitational interactions with one or more hidden companion stars buried

deep within the dust, which may be helping to shape those dramatic outflows.

This pre-planetary phase only lasts a few thousand years, an absolute blink in cosmic

terms.

So catching a nebula at this stage is like catching lightning in a bottle.

And the material being shed here is the same kind of carbon-rich star dust that ceded

our own solar system four and a half billion years ago.

Hubble has observed the egg nebula before, but this new image taken with the wide field

camera 3 combines multiple data sets to produce the most detailed portrait yet.

Thirty-five years in orbit, and Hubble is still delivering.

Now for a story that could fundamentally change how we think about Mars.

New research published in the journal Astrobiology is making the case that NASA's Viking missions

may have actually detected signs of life on Mars back in 1976.

We just didn't know how to read the data.

This is a big claim, so let's unpack it.

The Viking landers carried an instrument called the GCMS, the gas chromatography mass spectrometer,

which was designed to detect organic molecules in the Martian soil.

At the time, it returned what was interpreted as a negative result.

No organics found, case closed.

And that conclusion essentially shut down the debate for decades.

The Viking project scientist Gerald Soffin famously said, no bodies, no life.

And that became the textbook answer.

But here's the twist.

In 2008, NASA's Phoenix lander discovered perchlorates in the Martian soil.

Perchlorates are powerful oxidizing chemicals, and it turns out they break down organic molecules

when heated, which is exactly what the Viking GCMS did to its soil samples.

Though in 2010, astrobiologist Rafael Navarro Gonzales showed that if you take organic material

and heat it in the presence of perchlorate, you get methyl chloride and carbon dioxide,

which is precisely the chemical signature that Viking detected and dismissed as either

contamination or an unknown chemical process.

The lead author, Dr. Benner, puts it very directly.

The GCMS didn't fail to discover organics.

It did discover them through their degradation products.

We just didn't understand what we were looking at.

The team has even developed a model for what Martian microbes might look like.

They call it bar zoom.

That's bacterial autotrophes that respire with stored oxygen on Mars.

The idea is that these organisms could photosynthesize during the Martian day, produce and

store oxygen.

Ben used it to survive the freezing Martian nights.

I should emphasize, this doesn't prove there's life on Mars, but it does reopen a door

that was closed 50 years ago, and makes a compelling case that the evidence was there all

along, hiding in plain sight.

And it raises a fascinating question.

If we go back to Mars with modern instruments designed with percorates in mind, what else

might we find?

Our final story today is a bit of a cosmic cold case.

Remember comment C 2019 Y4 Atlas?

Oh, the pandemic comment.

It was discovered in December 2019, and as it flew toward the inner solar system in

early 2020, it brightened so rapidly that astronomers predicted it could become visible

to the naked eye, a real lockdown spectacle.

And then, like so many plans in 2020, it fell apart.

Literally.

In late April 2020, the comment dramatically disintegrated into dozens of pieces.

Hubble tracked about 30 fragments grouped into a few clusters of icy debris.

But here's the thing.

A new study in the Astronomical Journal by a team led by Salvatore Cordoba-Kihano at Boston

University has been asking if anything is still out there.

Did the comment completely destroy itself or could a chunk have survived?

The team scanned the skies in August and October of 2020 using the Lowell Discovery Telescope

in Arizona and the Zwicky Transient Facility, which surveys the entire Northern sky every

two nights.

They found nothing.

But, and this is the intriguing part, that doesn't necessarily mean there's nothing left.

Air analysis suggests that a fragment up to about half a kilometer wide could still exist,

but would be too small and too faint for those telescopes to detect.

It could be out there right now, quietly tracing the comment's original orbit back toward

the outer solar system.

The researchers pose a really thought-provoking question.

How many comments that we've assumed were completely destroyed might actually have surviving

remnants still orbiting the sun?

And there's a wonderful historical footnote here.

Comment Atlas is believed to be a fragment of the same parent body as the great comment

of 1844, which itself may have been visible to Stone Age civilizations about 5,000 years

ago when it swept past the sun.

So, somewhere out there, a tiny piece of a 5,000-year-old cosmic traveler might still be making

its lonely journey through the darkness.

I find that oddly beautiful.

Me too, and the study serves as a heads-up to astronomers.

Next time a comment breaks apart, be ready to keep watching, because the story might not

be over.
