Private Telescopes, Troubled Launch Pads, and Webb's Black Hole Breakthrough

Avery: Hello, and welcome to Astronomy Daily,

the podcast that brings you the universe, one

story at a time. I'm Avery, and as always,

I'm joined by the brilliant Anna.

Anna: Hi, Avery. And hello to all our

listeners. We have a busy show today

covering everything from a groundbreaking new

private space telescope to Russia's only

crewed launch pad. Running into some trouble.

Avery: Plus, we've got the James Webb Space

Telescope doing what it does best, peering

into the heart of our Galax. And we'll

look at some stunning new photos of home.

So let's get started. Anna, uh, tell us about

this new telescope.

Anna: Absolutely.

Our first story is a big one, though. It

comes in a small package. A new space

telescope named Mouth, about the size of

a mini fridge, just launched successfully

aboard a SpaceX transporter mission.

Avery: Okay, a, uh, mini fridge in space.

What makes this one so special?

Anna: Well, unlike Hubble or Webb, Malve is

owned by a private company, Blue Skies Space.

And this is the key difference. Its data will

also be private. Researchers will have to

subscribe to get access to the ultraviolet

spectra.

Avery: It collects a subscription model

for astronomical data. That's a

fascinating shift.

Anna: It really is. The mission was funded by a

mix of EU grants and private funding,

costing significantly less than comparable

NASA missions. It's built on a CubeSat

chassis, which is incredibly compact and

will spend three years in low Earth orbit

observing exoplanets, stellar flares

and monitoring stars.

Avery: So why would, uh, astronomers pay for this?

Is the data that unique?

Anna: It's about Access time on

telescopes like Hubble is at an extreme

premium, and most proposals get rejected.

Mauve offers a dedicated stream of

ultraviolet data, which is only accessible

from space. For many institutions, an

annual subscription could be a more reliable

way to get the specific data they need for

long term studies.

Avery: That makes sense. So this could be the start

of a whole new commercial market for

astronomical observation.

Anna: Exactly. Blue Sky Space already has

another mission, Twinkle, planned for

2027 to study exoplanet planet

atmospheres. With falling launch costs and

miniaturization, this could really change how

a lot of astronomical research is done.

Avery: Incredible. From a new beginning

to a potential problem.

Our next story takes us to the Baikonur

Cosmodrome and Kazakhstan. Anna, uh,

you have the details on some trouble for

Roscosmos?

Anna: That's right. Following the successful launch

of the Soyuz MS.28 crew to the

International Space Station, it seems the

launch pad itself itself sustained some

significant damage.

Avery: What happened exactly?

Anna: During the post launch inspection,

Roscosmos confirmed that a maintenance cabin

located in the Flame trench at site

31.6 collapsed. This is a

critical piece of hardware needed to prepare

rockets for launch.

Avery: And this is Russia's only active launch pad

for sending cosmonauts to the iss. Right.

Anna: That's the crucial part. They used to use the

historic site one, Gagarin's start, but

it was retired in 2020. So since

then, all Russian crewed and cargo flights

have gone from site 31. Roscosmos

says they have the spare parts and will

repair the damage, but some outside estimates

suggest it could take up to two years.

Avery: Two years. That would have a major

impact on their ISS operations. There's

a progress resupply mission scheduled for

next month.

Anna: Indeed, it's unclear at this point if that

schedule will hold or if another pad could be

adopted. The good news, of course, is that

the Soyuz MS.28 crew, including

NASA astronaut Chris Williams, arrived at the

station safely and are beginning their 8m

month stay.

Avery: A, uh, situation to watch for. Sure.

Alright, let's shift our gaze from Earth

orbit to the very center of our galaxy. And

the James Webb Space Telescope has been

watching the Milky Way's supermassive black

hole, Sagittarius A.

And it saw something spectacular.

Anna: It did. Astronomers used Webb

to observe flares from Sagittarius

A in mid infrared light

for the first time. We've seen these flares

in other wavelengths like near infrared

and radio, but. But mid infrared was

the missing piece of the puzzle.

Avery: Why is seeing it in a different wavelength so

important? Does it just look different?

Anna: It's about understanding the physics of

what's happening. The processes that create

these flares don't show up in all

wavelengths equally. By observing

in mid infrared, Webb is bridging the

gap between what we see in near infrared

and radio waves, giving us a more

complete picture of how the flare evolved.

Avery: So what did this new view reveal? Mhm.

Anna: Two really cool things. First, they

confirmed that a process called synchrotron

cooling is happening. This is when high

speed electrons lose energy by

emitting radiation. And that's what powers

the mid infrared light we're seeing.

Avery: Okay. Synchroton cooling. And the second

thing, this is the.

Anna: Big one, because the speed of that cooling

process depends on the strength of the

magnetic field. These new observations

allow scientists to measure the magnetic

field around the black hole more

directly and cleanly than ever before.

It's a critical parameter for understanding

how these cosmic giants are sculpted

and how they eject so much energy.

Avery: Wow. So we're getting a direct measurement of

the magnetic environment right next to a

supermassive black hole. That's A huge step.

Anna: It is. And the lead researchers

emphasized this was only possible because

of Webb's MIRI instrument, which can

observe in that specific wavelength with

incredible sensitivity, something

impossible from the ground.

Avery: Absolutely incredible. So now that we have

this new tool to measure the magnetic field

so close to the event horizon, we. What's the

next big question these researchers are

trying to answer? Are they looking for

something specific in future observations?

Anna: The ultimate goal is to understand how

Sagittarius A feeds and grows.

These flares are thought to be the crumbs

from its meals, gas and stars that

get too close. By studying the

magnetic field, scientists can build better

models of the accretion disk, which is the

swirling vortex of matter that feeds the

black hole. They want to understand how this

magnetic field extracts energy and

launches powerful jets of particles, a, uh,

phenomenon we see in more active

supermassive black holes across the universe.

Webb's observations are providing the crucial

ground truth for those theories.

Avery: Another win for Webb.

Okay, from one innovative space mission to

another. The European Space Agency just

launched its first, first scout mission.

Anna, uh, what is Hydro GNNS

scouting for?

Anna: As the name suggests, it's scouting for

water. Hydro GNNSS

consists of two small twin satellites

also launched on that same transporter 15

rideshare flight we mentioned earlier. Their

goal is to improve our understanding of

Earth's water cycle.

Avery: And how are they doing that? What's the

technology?

Anna: It's a really clever technique called GNSS

reflectometry. Essentially, the

satellites listen for signals from navigation

systems like GPS and Galileo.

They compare the signals they receive

directly from the navigation satellites with

the signals that have reflected off the

Earth's surface.

Avery: Right. And the way those signals change after

bouncing off the ground tells them something.

Anna: Exactly. It reveals valuable information

about key parts of the water cycle, such as

soil moisture, the freeze, thaw, state of

the ground, areas of flooding or

wetlands, and even the amount of

biomass in forests. These are all

critical for things like predicting floods,

planning agriculture, and understanding

carbon cycles.

Avery: You mentioned this is a scout mission. What

does that mean for esa?

Anna: It's a new approach for them, inspired by the

new space philosophy. Scout missions

are designed to be fast, agile and low

cost. They go from concept to launch in

just three years with a lean budget,

complementing their larger, more traditional

Earth explorer missions. Hydro

GNSS is the first of this new

family.

Avery: That's fantastic. It's great to see agencies

embracing faster, more innovative development

cycles.

Finally, let's bring it back home. NASA's

Osiris APEX spacecraft recently swung by

Earth and sent Back some souvenirs.

Anna: It did. Listeners will remember this

spacecraft as Osiris Rex, the

mission that successfully returned a sample

from the asteroid Bennu. After dropping off

its precious cargo, it was given a new name,

Osiris Apexed, and a new target,

the asteroid Apophis.

Avery: And to get there, it needed a little help

from home.

Anna: That's right. It performed a gravity assist

flyby of Earth, using our planet's

gravity to slingshot itself on a new course

towards Apophis. During this maneuver,

it flew just over 2,000 miles above the

surface and took some absolutely stunning

photos of Earth showing swirling cloud

patterns over blue oceans.

Avery: I saw those pictures. They're breathtaking.

It also got a shot of the moon, didn't it?

Anna: It did. As it was departing, it captured a

dramatic image of the Earth and Moon in the

same frame from about

370,000 miles away.

Besides being beautiful, these images

confirmed that its cameras are working

perfectly.

Ahead of its new mission and its.

Avery: Target, Apophis is a particularly

interesting asteroid, isn't it?

Anna: Very. Apophis will have its own

extremely close encounter with Earth on April

13, 20, 2029, passing closer

than many of our satellites. Osiris

Apex is scheduled to arrive shortly after

that pass, making it the first mission to

study how an asteroid is physically altered

by a planetary encounter. It will orbit

Apophis for 18 months, mapping it and

even firing its thrusters to stir up surface

dust for analysis.

Avery: It's amazing that they can get so much more

out of one spacecraft. Why is

Apophis in particular such a high priority

target? Is it just about the close flyby,

or is there something special about the

asteroid itself?

Anna: It's m a combination of both. The

2029 flyby is a once in a millennium

scientific opportunity to see how Earth's

gravity can physically alter an asteroid,

potentially triggering asteroid quakes or

changing its spin. But Apophis is

also an S type or stony asteroid,

which are very common in the inner solar

system and are the type most likely to pose

an impact hazardous. By studying its

composition and structure up close,

especially after it's been gravitationally

stressed, we gain invaluable data for

planetary defense models. It's a perfect

natural laboratory, an incredible.

Avery: Second act for a history making spacecraft.

Well, that's all the time we have for today.

From private telescopes and damaged launch

pads, to black hole flares and Earth scouting

satellites, it's been another busy day in

space.

Anna: It certainly has. Thanks for tuning in to
