Astronauts Return Plans, Space Farming Breakthroughs, and the James Webb's Cosmic Cat's Paw

Anna: Welcome to Astronomy Daily. I'm your host,

Anna, and I'm thrilled to have you join us

for another exciting dive into the cosmos.

Today we're covering some big headlines from

across our solar system and beyond. First up,

we'll hear about an astronaut mission

returning from the International Space

Station, wrapping up a busy period of

scientific research. Then we'll turn our

attention to the groundbreaking efforts to

cultivate fresh food in space, a crucial step

for future long duration missions to the Moon

and Mars. Next, we'll celebrate the James

Webb Space Telescope's third year of

operations with an absolutely stunning new

image that reveals the secrets of a cosmic

cat's paw. And finally, we'll shift our

gaze to our own star, the sun, as an

active sunspot that's been putting on an

explosive show with magnetic bombs turns

its fiery gaze towards Earth. So

buckle up and let's explore the latest in

astronomy.

First up today we have news from the

International Space Station where the Axiom

Mission 4, or Axe 4 Crew is making

final preparations to return to Earth after a

highly productive 2.5 week research

mission. Mission managers have given the

green light for Commander Peggy Whitson,

pilot Shubanshu Shukla and mission

specialist Slawash Usnansky Wisniewski and

Tibor Kapu to board their SpaceX

Dragon spacecraft. They are set to undock

from the space facing port on the Harmony

Module this coming Monday, July 14th

at 7:05am um, Eastern Daylight Time.

This private quartet has had an incredibly

busy schedule packed with a diverse array of

scientific investigations aimed at advancing

our understanding of human health in space,

sustainable life support systems and next

generation technologies. Just a few days

ago, the Axe 4 crew was focused on collecting

blood samples for a comprehensive biomedical

research study crucial for understanding how

the human body adapts to microgravity.

They also delved into the potential of

microalgae, exploring its viability as a

food source for future crews and its role as

a key component in biological life support

systems aboard spacecraft. Imagine

the possibility of astronauts cultivating

their own fresh food during long duration

missions. In another fascinating area, the

crew investigated nanomaterials, which could

form the basis for constructing advanced

wearable devices designed to comfortably

monitor crew health, providing real time data

on their vital signs and overall well being.

As the mission drew to a close, the Axe 4

team spent their final days finalising

several other important science experiments.

This included an electrical muscle

stimulation study which could offer insights

into maintaining muscle strength in low

gravity. They also tested suit fabrics

engineered to promote thermal comfort during

exercise, a critical factor for astronaut

performance. And in an effort to understand

the psychological aspects of space travel,

they filmed crew activities for a behavioural

health study. On Sunday, their focus

shifted to the meticulous task of packing all

the science gear, including precious research

samples, along with their personal items and

other cargo, securely inside the Dragon

spacecraft for retrieval once they are back

on Earth.

It wasn't just the Axe 4 crew who were busy,

though. The International Space Station's

resident crew members were also deeply

involved in assisting and continuing their

own research. NASA flight engineer Anne

McClane, for instance, helped the Axe 4 crew

gather hardware and other items for packing.

She also continued assisting the private

crewmates as they utilised the station's

resources for their ongoing science

investigations. NASA flight engineer

Nicole Ayers spent her day in the Columbus

laboratory module, where she assisted the Axe

4 crew by spinning astronaut blood samples in

a centrifuge and then carefully stowing them

in a science freezer for preservation. She

later moved to the Quest airlock to transfer

water into a pair of spacesuits. NASA flight

engineer Johnny Kim also lent a hand with the

blood sample processing before spending the

rest of his day inspecting electronics gear

and swapping computer cables.

Meanwhile, station commander Takuya Onishi

from the Japan Aerospace Exploration Agency,

or jaxa, started his day processing saliva

samples for analysis and then recording his

sleep experience for a computer

questionnaire. He later worked in the

Tranquilly module, replacing orbital plumbing

hardware before deactivating and stowing a

microscope in the Kibo laboratory module.

From the Russian segment, Roscosmos flight

engineers Sergey Ryzhikov and Alexei

Zubritsky took turns pedalling on an exercise

cycle while wearing electrodes. This

physical fitness evaluation provides

researchers with crucial data to understand

the energy requirements crew members need for

strenuous activities like spacewalks. And

flight engineer Kirill Peskov replaced fire

extinguishers in the Poisk, Rassvet and

Zvezda modules, then checked computer

hardware that supports the European robotic

arm. It truly takes a global effort to keep

the station running and to push the

boundaries of science.

Speaking of food for future space missions,

one of the biggest challenges facing

permanent human bases on the Moon and Mars is

the ability to grow fresh food hundreds of

thousands of kilometres from Earth. But

exciting news on this front. The seeds of a

rice variety ideal for growing outside Earth

might soon be sprouting thanks to an

innovative collaboration called the Moon Rice

Project. This joint effort brings together

the Italian Space Agency, the University of

Milan, the University of Rome, and the

University of Naples, all working to create

the ideal food crop for future deep space

outposts Dr. Marta Del Bianco,

a plant biologist from the Italian Space

Agency, explains that they are essentially

trying to solve the same problems we face

here on Earth, but in a much more extreme

environment. Given the negative effects space

can have on human health, it's crucial for

astronauts to have readily available nutrient

rich food. Currently, space exploration

relies heavily on prepackaged meals delivered

during resupply missions, which rarely

include fresh ingredients. One of the major

hurdles for farming in space is the sheer

size of crops. Even small varieties like

dwarf rice are still too big to depend on in

the confined spaces of a spacecraft or lunar

habitat. What we need is a super

dwarf, says Del Bianco. However,

creating a super dwarf rice comes with its

own set of challenges. While scientists can

manipulate a plant hormone called gibberellin

to reduce the height of rice plants, this can

negatively affect seed germination and

production. As Del Bianco points out, they're

not an ideal crop, because in space you don't

just have to be small, you must also be

productive. The project is delving into

various aspects of rice biology and genetics

to develop this perfect crop, one that can

nourish humans on long duration missions. The

project is only nine months into its four

year plan, but the preliminary results are

already looking very promising. Dr. Del

Bianco's specific focus is on microgravity

and how these rice plants will cope in that

unique environment. To simulate

microgravity on Earth, they continually

rotate the plant so it's pulled equally in

all directions by gravity, effectively

confusing the plant about which way is up or

down. Additionally, researchers at the

University of Milan and have identified rice

mutant varieties that grow to a mere 10

centimetres high. While the team in Rome has

pinpointed genes that can maximise growth and

production beyond just size and yield,

Del Bianco and her team are also aiming to

increase the protein content of the rice, as

meat production for long duration missions

will simply not be effective. Apart from

being highly nutritious, they hope this crop

will also offer significant benefits for the

astronauts. Well, being, watching and guiding

plants grow is known to be good for humans.

And while pre cooked or mushy food might be

fine for short trips, it could become a real

concern on longer missions.

Imagine the psychological boost of having

fresh growing food in a sterile space

environment. As Del Bianco puts it,

if we can make an environment that physically

and mentally nourishes the astronauts, it

will reduce stress and lower the chances of

people making mistakes. This

groundbreaking research isn't just for space

either. The hope is that if they can develop

such a robust crop for space, it could also

be used in challenging terrestrial

environments like the Arctic Antarctic

deserts, or even in places with very limited

indoor growing space. The preliminary

findings of this fascinating project were

recently presented at the Society for

Experimental Biology Annual Conference

in Antwerp, Belgium.

From the challenges of growing food in space,

let's now turn our gaze to something truly

spectacular that celebrates the third year of

operations for the James Webb Space

Telescope. Prepare to peer into the heart of

a cosmic the Catspaw Nebula,

a giant complex molecular cloud aptly named

for its striking resemblance to a set of

enormous tow beans. This isn't just a squishy

looking cosmic temptation. The Cat's Paw

Nebula, located approximately 4,000 light

years away in the constellation Scorpius, is

a vibrant site of ongoing star formation.

Here, massive stars are in the active process

of forming, often obscured by vast clouds of

dust and molecular gas. This is where

JWST truly shines.

Infrared light, unlike other wavelengths, has

the remarkable ability to penetrate these

dense clouds where other light would simply

scatter off the particles. As the James Webb

Space Telescope is an infrared telescope, it

is perfectly equipped to peer directly

through the dust and reveal the wild,

intricate process of star formation unfolding

within. It's an excellent tool for

investigating these cosmic nurseries. The

telescope's Near Infrared Camera, or

nircam, captures different stages of this

stellar birth process throughout the scene.

In the upper middle chamber, a uh, structure

affectionately nicknamed the Opera House, we

can spot a baby yellow star actively

illuminating and blowing away the surrounding

dust. This represents one of the final stages

of a star's formation. Meanwhile, in the

thick brownish dust right in the middle of

the image, you can see glowing fiery red

blobs. These are sites where star formation

is still actively underway, heavily obscured

by the nebular material. An orange region in

the upper right with a noticeably low star

count indicates an area where star formation

is in its even earlier stages.

The beautiful opalescent blue glow

illuminating the hollowed out areas comes

from the light of fully formed stars

scattered throughout the cloud. And those

intriguing filaments of dust through which

very little light penetrates suggest areas

of such high density that the star

formation process is just beginning.

Dense knots of gas collapsing under gravity

to form the very seeds of baby stars.

Against this backdrop, bright blue white

stars gleam with crackling clarity. These

are the fully formed stars that have

successfully blown away their surrounding

material, now free to shine their light

across the cosmos. It's a truly

magnificent and dynamic portrait of stellar

birthday. If you'd like to see this

breathtaking image for yourself, wallpaper

sized versions are available for download on

the European Space Agency's JWST

website. I'll drop a link into the show notes

for you to check it out. In all its glory,

it's an incredible way to celebrate three

years of groundbreaking discoveries from this

phenomenal telescope.

Now let's shift our focus closer to home to

our very own star, the sun, which is putting

on quite a show. A new sunspot Designated

Region 4136 has recently emerged over the

sun's eastern limb and it's crackling with

dozens of magnetic explosions known as

elearmin bombs. French

astrophotographer Philippe Tosi captured this

incredible activity on July 10 from Nimes,

France, using an H alpha filter to reveal the

fine details of these explosions. The image

shows these elearmin bombs popping like

fireworks near a sunspot that has already

unleashed multiple M M class solar flares,

which are mid level eruptions on the solar

flare scale. Ellerman bombs were first

described in the early 20th century by

physicist Ferdinand Elearman. These

energetic events occur in the lower solar

atmosphere and are primarily driven by

magnetic reconnection. This is a process

on the sun where oppositely charged magnetic

fields meet and then explosively reconfigure

rec releasing a burst of energy. Each

Elelerman bomb might release an amount of

energy equivalent to roughly 100,000 World

War II era atomic bombs. While that's

only about 1 millionth the energy of a large

solar flare, these mini explosions are highly

significant. They are seen as key indicators

of magnetic complexity within a sunspot. When

opposite magnetic polarities collide and

reconnect, they quickly release energy in

these bright rapid flashes. That

complexity could potentially mean even bigger

fireworks ahead. With sunspot region

4136 now rotating to face Earth,

it could pose a threat for stronger space

weather events in the coming days. M um class

flares like those already observed have the

potential to cause brief radio blackouts and

minor satellite disruptions if they are aimed

directly at our planet. Scientists and

skywatchers alike will certainly be keeping a

very close eye on this active sunspot region

as it continues its rotation into an Earth

facing position. It's a dynamic reminder

of the powerful processes constantly at play

on our star. That's all for this episode

of Astronomy Daily. Thank you for joining us

for another exciting journey through the

cosmos. It's truly incredible what we

continue to discover, from returning

astronauts and future food sources for space
