Europe's Space Independence: Nordic Launch Sites, July Meteor Showers, and a Cosmic Retraction

Anna: Welcome to Astronomy Daily, your daily dive

into the cosmos. I'm Anna and today

we're starting close to home, looking at

Europe's ambitious push to achieve greater

independence in space, with new launch sites

emerging in the Nordic region. Then we'll

turn our gaze to the night sky as July

promises a spectacular show with three major

meteor showers about to light things up.

Later in the programme, we'll delve into a

curious case of a retracted cosmic

discovery that highlights the rigorous nature

of scientific investigation. And finally,

we'll journey to the far side of the moon to

learn about an ambitious mission designed to

peer back into the universe's dark ages.

So settle in as we launch into today's

astronomical headlines. Europe

is currently embarking on an ambitious

journey to reduce its reliance on US space

capabilities, uh, a move significantly

spurred by recent geopolitical events. The

America first policies, coupled with the

ongoing conflict in Ukraine, have underscored

the urgent need for Europe to bolster its

independent capabilities, not just in

defence, but crucially, in space operations.

The concern, for instance, that a figure like

Elon Musk might limit Ukraine's access to

vital Starlink satellite communications has

only heightened the urgency for Europe to

cultivate its own alternatives. The

statistics highlight the challenge. In

2024, the US conducted a, uh,

staggering 154 launches into

orbit, while Europe managed just three.

And out of $143 billion

in global public investment in space ventures

last year, Europe accounted for only

10%. With the trend moving

towards lower Earth orbit satellites, which

are cheaper but require deployment in larger

numbers, the pressure is on. A Goldman

Sachs report even estimates a tenfold

increase in LEO satellite launches in the

next five years, potentially reaching 70,000.

As European Commissioner for Defence and

Space Andreas Kubelius put it, Europe needs

its own autonomous launching possibilities.

Currently, Europe's only spaceport is located

in French Guiana, some 7,000 kilometres from

Paris. While their new Ariane 6 rocket,

launched earlier this year, can carry a

bigger payload than SpaceX's Falcon 9, it's

not reusable and comes with a higher cost per

launch. This is where the budding Nordic

Spaceports in Sweden and Norway come into

play, offering Europe a rare advantage.

Take the S Range Space Centre in Sweden.

Situated 200 kilometres above the Arctic

Circle, it boasts an expansive

5,200 square kilometres of uninhabited

land, making it ideal for recovering rocket

parts. This unique feature, combined with its

proximity to railways and an airport in

Kiruna, gives it a significant edge. S

Range, which has been operational since 1964

for research rockets, was inaugurated as

mainland Europe's first orbital launch site

in 2023. Preparations are well underway, with

new launch pads and facilities being readied.

Ezrange has strategically opted for existing

hardware, signing contracts with US rocket

manufacturer Firefly and South Korea's

Perigee, giving it multiple launch options.

Firefly, for instance, plans to launch from

Asrange from 2026 and offers a rapid

response service, potentially sending rockets

into space within 24 hours to meet urgent

needs like replacing a failing satellite.

Then there's the Andoya spaceport, an island

base in northern Norway. In March,

Andoya successfully conducted the first test

launch of a small rocket from German startup

Isar Aerospace. While it only

flew for 30 seconds before falling into the

sea, it was deemed a success and points

towards future capabilities.

Isar is aiming for its first commercial

flights next year, and its CEO Daniel

Metzler highlighted the enormous interest

from defence ministries even before a

successful orbital launch. He noted that the

renewed focus on European defence was

significantly driven by geopolitical shifts.

Both Esringe and Andoya are seen as Europe's

best hope for securing independent access to

space in the coming years. While these Nordic

ventures are still in their early stages

compared to established leaders like SpaceX,

with its reusable rockets and lower costs,

they represent a critical step towards

Europe's space autonomy. The goal is to

have all technical systems in place and

thoroughly tested, with Asrange expecting to

have its entire base ready within about a

year. The timeline is aggressive, but

the determination to achieve independent

space capabilities is clear.

Now let's shift our gaze from Earth's orbital

ambitions to the celestial wonders unfolding

above us. The second half of July and the

early days of August are shaping up to be a

spectacular time to step outside and marvel

at the night sky. That's because three of the

year's most captivating meteor showers are

about to peak, each with its own unique

characteristics. For those in the northern

hemisphere, the warm summer temperatures make

meteor spotting a perfect evening activity,

while down south, longer nights offer

extended viewing opportunities. You won't

need any specialised equipment to enjoy these

cosmic displays, though for some, binoculars

might just enhance the experience. Meteor

showers occur when our planet, on its annual

journey around the sun, passes through the

trails of debris left behind by comets or

asteroids. As these celestial objects orbit,

they shed material that remains along Earth's

orbital path. When our planet enters this

cloud of detritus, tiny pieces of rock and

dust smack into Earth's atmosphere, burning

up due to the intense friction. This creates

those luminous trails, or fireballs, that we

can see with the naked eye, first up,

making their appearance around July 12th and

peaking from July 29th to 30th are the

alpha Capricornids. These meteors are

visible in both northern and southern skies.

They originate from a short period comet

named 169neat,

which orbits the sun once every 4.2 years,

and their radiant point, or the spot they

appear to emerge from, is in the

constellation Capricorn.

While the Alpha Capricornids aren't known for

their sheer numbers, producing only about 5

meteors per hour at their peak, what they

lack in quantity they more than make up for

in brilliance. These meteors shine

exceptionally brightly, often producing

stunning fireballs that can even cut through

light pollution. This year the peak

coincides with a low illumination waxing

crescent moon, further increasing their

visibility. The best time to catch these

bright beauties will be in the evening

starting around 10pm local time.

Next the famous and much anticipated Perseids

begin to appear around July 17, reaching

their peak from August 12 to 13.

Primarily a northern Hemisphere treat, the

Perseids originate from Comet Swift Tuttle, a

short period comet with a longer orbital

period of 133 years. Their

radiant is located near the constellations of

Perseus, Cassiopeia and

Camelopardalis. The Perseids are known for

being prolific, often showering the sky with

numerous meteors. While this year's peak

might be a bit complicated by a waxing

gibbous moon, the shower will remain active

throughout the entire month of August,

offering plenty of chances to catch them.

Your best bet for viewing the Perseids is in

the early morning hours between midnight and

dawn. Finally, we have the southern Delta

Aquariids, which start on July 18th

and also peak from July 29th to 30th,

sharing the stage with the Alpha

Capricornids, these meteors are believed to

come from the short period Comet

96PMachholz, orbiting

the sun every 5.27 years. With a

radiant point in the constellation Aquarius,

this shower produces a respectable 20 to 25

meteors per hour during its 48 hour peak

window. They tend to be a bit fainter and

don't leave strong trails, so if you have

binoculars they might come in handy.

Fortunately, this year's peak occurs during a

waxing crescent Moon that sets before the

radiant is high, providing pretty optimal

viewing conditions, especially between

midnight and dawn. Keep an extra eye out for

the southern Delta Aquarids this year. As on

two past occasions in 1977 and

2003, they put on a much stronger show than

usual, so there's always a chance for a

surprise to make the most of your meteor

shower viewing experience, consider

downloading a sky watching app like Starwalk

to help you locate the constellations and

plan your viewing times. And don't forget to

pack all the creature comforts, a comfy

blanket, some snacks and perhaps a camera if

you're hoping to capture the moment.

Happy sky gazing from

dazzling meteor showers we now turn our

attention to another fascinating corner of

astrophysics where a recent development has

sent ripples through the scientific

community. Astronomers have been captivated

by fast radio bursts, or FRBs,

mysterious millisecond long explosive events

believed to originate from highly magnetised

neutron stars in distant galaxies.

One particular event, dubbed FRB2019

1221A detected in 2019 by the

CHIME radio telescope, initially seemed to be

a groundbreaking discovery. This burst was

unusual, three seconds long, with nine

regular sub bursts every 217 milliseconds.

This rhythmic pulsing strongly suggested a,

uh, neutron star origin like a pulsar.

Its significant signal dispersion indicating

intervening matter, led the team to conclude

it came from 3 billion light years away.

For a pulsar to be seen at such a distance,

it would need incredible luminosity, leading

to the exciting conclusion that this was the

first regularly pulsing FRB ever observed.

However, the claim about FRB2019

1221A has now been officially

retracted. The discovery team announced that

a critical calibration problem in the CHIME

telescope had led to a 20 degree error in

pinpointing the burst's true location. CHIME

is a unique instrument where sky position is

electronically derived, requiring precise

daily calibration. The error was attributed

to an extremely rare confluence of

circumstances, including heavy rain and

strong local radio interference. With the

correct sky position, it became clear the

signal was not from a far off galaxy, but

from a familiar pulsar within our Milky Way

PSR J0248

6021 in Cassiopeia.

This closer location means the observed

signal dispersion is fully attributed to

interstellar matter within our galaxy. While

a retraction might seem like a setback, the

scientific community lauded the team's

transparency. As one scientist noted,

correcting your errors helps the science go

forward. It's a powerful example of

science's self correcting nature, turning

challenges into learning opportunities.

From correcting our understanding of distant

bursts, let's now journey to the far side of

the Moon where scientists are proposing an

ambitious mission to unravel the universe's

earliest secrets. For decades,

astronomers have yearned to observe cosmic

dawn. The period roughly 50 million to

1 billion years after the Big Bang, marking

the formation of the very first galaxies.

Understanding these nascent galaxies is

fundamental to comprehending cosmic

evolution, including the roles of dark matter

and dark energy. The challenge lies in

observing the preceding cosmic dark ages,

when the universe was predominantly filled

with neutral hydrogen. The light from this

period is so so redshifted that it's only

visible in the radio spectrum, making it

incredibly difficult to detect with modern

instruments on Earth due to overwhelming

background noise and radio frequency

interference. This is precisely why the

Royal Astronomical Society is proposing

the Cosmo Cube mission to the far side of the

Moon. The Moon's far side offers a

uniquely quiet radio environment shielded

from Earth's interference. As Dr. Eloy Dilera

Acedo, who presented the proposal vividly put

it, it's like trying to hear that whisper

while a loud concert is playing next door.

To detect the faint radio signal from the

universe's primordial hydrogen, silence is

key. Cosmo Cube will be a small satellite

with a precision calibrated radiometer

operating at low frequencies. This will allow

it to pick up extremely faint radio signals

that have travelled over 13 billion years to

reach us. Such observations could unlock

answers to profound cosmological mysteries,

from the perplexing Hubble tension to

narrowing the search for the elusive dark

matter particle. The mission aims to help us

understand how our universe transformed from

a simple dark state into the complex

star filled cosmos we see today.

Developed by a UK led international

consortium, the Cosmo Cube project team is

already creating and testing functioning

prototypes. The ambitious vision is

for the mission to be ready to launch in four

to five years with the ultimate goal of

reaching lunar orbit before the end of the

decade, poised to listen to that ancient

whisper from the cosmos.

And that brings us to the end of another

journey through the cosmos. On Astronomy

Daily Today, we've explored Europe's

ambitious strides towards space independence.

With new Nordic launch sites poised to

reshape the global space landscape. We then

looked skyward to prepare for July's

spectacular meteor showers, offering a guide

to catching those dazzling Alpha

Capricornids, Southern Delta Aquariids and

the ever popular Perseids. We also

delved into the intriguing story of a

retracted fast radio burst discovery, a

testament to the rigorous self correcting

nature of science. And finally, we

soared to the far side of the Moon and

envisioning the Cosmo Cube mission and its

quest to listen to the universe's earliest

whispers, potentially unlocking secrets of

the cosmic dark ages and dark matter.
