Welcome to Astronomy Daily, your source

for the latest space and astronomy news.

I'm Anna.

And I'm Avery.

We're bringing you Tuesday, February 3rd's biggest

stories from across to Cosmos.

Today we're covering a setback in NASA's Artemis II

preparations, a bold new vision from Elon Musk that's

raising eyebrows across the space industry,

and NASA's announcement of a fifth private astronaut

mission to the International Space Station.

We'll also explore some dramatic solar activity

that's lighting up our sun, NASA's newest mission

to map the boundaries of our solar system,

and an exciting opportunity for aspiring space

professionals in Europe.

Let's dive right in with our top story today.

NASA's Artemis II mission hit a snag

during a critical pre-launch test over the weekend.

The wet-tress rehearsal countdown

was terminated at the T5 minute and 15 second mark

due to a liquid hydrogen leak.

For anyone not familiar, a wet-tress rehearsal

is essentially a full-launched emulation, where

they load the rocket with propellant

and run through the entire countdown sequence,

stopping just short of ignition.

It's one of the final major tests

before an actual launch.

Exactly.

And this particular leak occurred at the interface

of the tail service mast umbilical,

which had already experienced high concentrations

of liquid hydrogen earlier in the countdown.

The launch control team had to work to ensure

the space launch system rocket was in a safe configuration

and begin draining its tanks.

Now, it's worth putting this in perspective.

Hydrogen leaks are notoriously challenging

to deal with in rocketry.

Hydrogen is the smallest molecule,

which means it can escape through incredibly tiny gaps.

NASA actually dealt with similar issues

during the Artemis I countdown back in 2022.

That's a good point.

And while this is definitely a setback,

it's exactly why we do these rehearsals

to catch problems and fix them before astronauts are on board.

The Artemis II crew of Reed Wiseman, Victor Glover,

Christina Koch and Jeremy Hanson

are scheduled to become the first humans

to fly around the moon in over 50 years.

The team at Kennedy Space Center

will now need to analyze what went wrong,

make repairs and potentially schedule

another wet dress rehearsal.

This could impact the launch timeline,

though NASA hasn't announced any official changes

to the mission schedule yet.

We'll definitely be keeping a close eye on this one.

Moving on to our next story,

which involves some pretty ambitious claims from SpaceX.

Elon Musk has announced that SpaceX

has acquired his artificial intelligence company XAI

and with that acquisition comes a vision

that sounds like something straight out of science fiction,

orbital data centers.

The numbers here are staggering, Anna.

The information quoted unnamed sources saying XAI

was valid at $250 billion,

while SpaceX was valid at a trillion dollars.

That would make SpaceX the most valuable

private company in the world.

Though as one investment advisor quipped,

Musk essentially had a short negotiation with himself

since he held controlling interests in both companies.

But the real story here is what Musk plans to do

with this combined entity.

Right, Musk is proposing to put up to a million satellites

in low-earth orbit to create a constellation

of orbital data centers.

The idea is that these would address the major challenges

facing ground-based data centers,

the massive electricity requirements

and the water needed for cooling.

His pitch is compelling from an engineering standpoint.

In space, you have mere constant solar power

with no nighttime interruptions,

no atmospheric interference, and no need for water cooling.

As Musk wrote, it's always sunny in space.

He's framing this as a step towards becoming

a Kardashev Type II civilization,

one that can harness the sun's full power.

He even suggested that future AI satellites could be built on

and launched from the moon using electromagnetic mass drivers.

But here's where the skepticism comes in.

Industry observers are raising serious questions.

Jim Cashel, author of the Greek Connecting,

suggested the million satellite figure

might be more about publicity

and the potential SpaceX IPO than realistic planning.

And Martin Pierce from the information

pointed out the headspinning array

of technical and financial impediments.

Those challenges include protecting computers from radiation,

maintaining hardware in orbit,

the enormous expanse of getting everything into space,

and competing with tech giants like Google and Metta

who have cast-generating advertising businesses.

Some analysts suggest this move is financially motivated,

a way to throw a lifeline to XAI,

which merged with X last year

and has been facing financial troubles.

The timing ahead of a possible SpaceX IPO

is certainly interesting.

It's definitely an ambitious vision,

whether it's brilliant foresight

or science fiction remains to be seen.

Either way, it sparked a fascinating debate

about the future of space-based infrastructure.

Speaking of space infrastructure,

let's talk about something

that's actually happening right now.

NASA's commercial crew program.

NASA has ordered a fifth private astronaut mission

to the International Space Station from Axiom Space

with a launch targeted for no earlier than January 2027

from Kennedy Space Center in Florida.

This continues the series

of commercially sponsored crewed missions

to the orbital laboratory

under NASA's commercial space strategy.

NASA Administrator Jared Isaacman

emphasized that commercial space activity

has become a present reality

rather than a distant prospect.

This mission, designated Axiom Mission 5,

is expected to spend up to 14 days aboard the station.

The final launch date will depend

on overall spacecraft traffic

and other operational planning factors.

Basically, coordinating the busy schedule

of visiting vehicles.

Dana Weagle, manager of NASA's

International Space Station program,

noted that these private astronaut missions

allow the station to serve as a proving ground

for new markets and technologies

while supporting science, research, and outreach

that contribute to a growing space economy.

Under this mission order,

Axiom Space will propose four crew members

for review by NASA and its international partners.

Once approved,

though undergo joint training with NASA,

partner agencies, and the launch provider.

What's particularly interesting

about this arrangement is the exchange of services.

Axiom Space will purchase mission services from NASA

like crew consumables, cargo delivery, and storage.

In return, NASA will acquire from Axiom Space

the capability to return scientific samples

that must remain cold during transit.

Jonathan Certain, president and CEO of Axiom Space,

said the four earlier Axiom missions

have expanded the global community of human space explorers

and yielded insights supporting development

of the planned Axiom Station.

That's the key here.

Axiom Station is intended to succeed

the International Space Station

as a next-generation commercial platform

once the current laboratory is retired.

These missions are helping build towards that future.

It's a great example of NASA's strategy

to transition low-earth orbit services to private providers

while the agency concentrates on deep space exploration

like the Artemis missions to the moon.

Absolutely.

Now let's turn our attention

to some dramatic activity happening much closer to home

on our own star.

The sun has been putting on quite a show over the past 24 hours.

A rapidly growing sunspot has fired off

at least 18 M-class flares and three X-class flares,

including an intense X-8.3 eruption.

The strongest solar flare of 2026 so far.

To put that in perspective for our listeners,

solar flares are ranked from A, B, and C up to M and X

with each letter representing a 10-fold increase in energy.

So X-class flares are the most powerful explosions

the sun can produce.

And the number after the X tells you how intense it is

within that class.

The culprit is sunspot region 4366,

which spaceweather.com described as a solar flare factory.

This region has grown rapidly in just a few days

and shows no signs of slowing down.

The X-8.3 flare peaked at 6.57 pm Eastern time

on February 1, unleashing a blast of extreme ultraviolet

and X-ray radiation that ionized Earth's upper atmosphere.

This triggered strong R-3 radio blackouts

across parts of the South Pacific.

Eastern Australia and New Zealand

reported shortwave radio disruptions.

These blackouts happen because the intense radiation

from the flare alters the ionosphere,

which radio signals bounce off of for long-distance communication.

Now, what everyone wants to know is,

will we see auroras from this?

Scientists are watching for coronal mass ejections

that could follow these flares.

Early analysis of a CME linked to the X-8.3 eruption

suggests most of the solar material will pass north

and east of Earth.

There's a possibility of a glancing blow around February 5,

which could briefly elevate geomagnetic activity

and increase the chances of auroras at high latitudes.

But forecasters stress it's too early to know for certain.

The bigger concern is that some spot AR-4366 remains highly active

and continues to rotate into an Earth-facing position.

That raises the chance that future eruptions

could launch CMEs more directly toward our planet.

Noah forecasters expect more exciting space weather activity

from this region in the coming days.

So aurora casers should definitely keep an eye

on space weather forecasts over the next week.

It's a great reminder that we're still in solar maximum,

the period of greatest solar activity

in the sun's 11 year cycle.

We can expect more of these dramatic events

over the next year or so.

Absolutely.

From watching the sun, let's zoom out

to the boundaries of our entire solar system.

DASA's IMAP mission, that's the interstellar mapping

and acceleration probe, officially began its two-year

primary science mission on February 1.

IMAP's job is to explore and map the boundaries

of our heliosphere, which is the protective bubble

created by the solar wind that encapsulates

our entire solar system.

Think of it as our cosmic shield against interstellar radiation.

The mission launched on September 24th, 2025,

and relies on 10 scientific instruments

to chart what's happening in space.

That includes high energy particles

from the sun, magnetic fields in interplanetary space,

and even dust from exploded stars in interstellar space.

What makes this particularly exciting

is that IMAP is investigating some of the most important

questions in heliophysics, how charged particles

from the sun get energized, and how the solar wind

interacts at its boundary with interstellar space.

And there's a practical benefit, too.

Some of IMAP's data is being fed into the eyelert system,

which stands for IMAP active link for real time.

This broadcasts near real time observations

of space weather headed toward Earth.

That data can inform forecasters

who issue warnings about potential adverse space weather

effects on spacecraft and astronauts.

Though IMAP is both advancing

or scientific understanding and providing

practical benefits for space operations.

The mission is led by David McComis, a principal investigator

and professor at Princeton University

with an international team of 27 partner institutions.

Johns Hopkins Applied Physics Laboratory

managed development and operates the mission.

It's the fifth mission in NASA's Solar Terrestrial Probes

program, and it's going to give us unprecedented insights

into the edge of our solar neighborhood

over the next two years.

Beaking of opportunities to advance our understanding

of space, let's wrap up with some news

for aspiring space professionals.

The European Space Agency has opened applications

for its 2026 graduate trainee program,

offering an incredible opportunity for recent graduates

passionate about engineering, science, IT, or business.

This is a unique professional experience

where trainees become part of teams of scientists,

engineers, and business professionals from all over Europe,

working together on inspiring space missions

in an international, multicultural environment.

The positions are one-year contracts

with possible extension to a second year.

trainees get 2.5 days of paid leave per month

and receive a monthly salary that's exempt

from national income tax and ESA member states.

ESA also reimburses travel expenses

at the beginning and end of the contract.

Provides an expatriation or installation allowance

for those moving from another country

and includes affiliation to ESA's comprehensive

social security and pension schemes.

To be eligible, you need to be a student

in the final year of a master's degree

or a recent graduate.

You must have graduated by the time you start your traineeship

and be able to provide a copy of your diploma

within three months of starting.

Important note, you shouldn't have more than one year

of professional experience after graduation.

And you must be a citizen of one of the ESA member states,

associate members, European cooperating states,

or Canada as a cooperating state.

ESA is holding three information sessions in early February

where prospective applicants can learn more

about the program and ask questions.

The first one is February 5th.

There is another on February 12th

and a third on February 17th.

Each candidate can submit up to three applications.

So it's worthwhile exploring multiple opportunities

that match your academic background and aspirations.

All the details in application portal

can be found at jobs.esa.int.

I'll be sure to add that link in the show notes.

This is genuinely a fantastic opportunity

for anyone looking to start a career in Europe space sector.

ESA has a long history of groundbreaking missions

and continues to be at the forefront of space exploration,

earth observation, and space science.

It's programs like this

that help develop the next generation of space professionals

who will be working on tomorrow's missions

to explore our solar system and beyond.

And that wraps up today's episode of Astronomy Daily.
