Will Russia Attack the Starlink Constellation? Through a new registration process, SpaceX has found a way to block Russia’s military from using Starlink on Ukraine’s territory, a move that has resulted in major battlefield losses for the invading ...

Russia may be a waning space power when it comes to civilian technology, in the military space arena it is actually much better equipped than all the European countries combined. My latest story for @supercluster.com www.supercluster.com/editorial/wi...

Scientists measure air pollution from reentering SpaceX rocket in real-time: 'It's never been done before' "This study represents an important milestone in observing the influence of space sector activities on the atmosphere."

Researchers track air pollution arising from space debris re-entry for the first time in real time. #spacedebris

Stopping the European Space Startup Exodus Young space startups have been struggling in Europe for years. The problem has become so widespread that insiders refer to it as the 'European Space Start-up Exodus.'

Investigating the European space start-up exodus in this piece for @supercluster.com Why are space start-ups struggling in Europe so much that their only option may be relocating to the U.S.? Are there any signs that things might change? www.supercluster.com/editorial/st...

Seriously? Instead of addressing bad eating habits and lack of exercise take drugs. Instead of addressing trauma and your shit life, take anti-depressants. Like what?

Can Space-Grown Crystals Boost AI Efficiency? Space Forge's orbital furnace could redefine semiconductor production with space-grown crystals.

Can made-in-space semiconductors and optical fibers revolutionize computing? Do improvements in crystal structure possible in orbit justify the cost of developing orbital foundries, return capsule and launching stuff to space?

UK government proposes 30% budget cut to astronomy and physics research: 'It's pretty disastrous' "You can't have a cut of that scale and not expect to see a massive impact."

UK to slash astronomy budget by 30%. The move will prevent the UK from harvesting scientific return on its investment into international projects such as the Square Kilometer Array Telescope Observatory and the European Southern Observatory. @royalastrosoc.bsky.social www.space.com/astronomy/uk...

Astronomers relieved as industrial plant threatening Earth's darkest sky gets cancelled "When the cancellation is confirmed, we'll be relieved."

Some good news for astronomy at last. A light polluting hydrogen plant planned to be built in the vicinity of one of the world's top observatories will not go ahead. #lightpollution #Paranal #europeansouthernobservatory www.space.com/astronomy/as...

Stratospheric internet could finally start taking off this year High-altitude platforms could help connect over 2 billion people around the world who are still offline.

Satellites haven't succeeded. But could stratospheric airships and uncrewed planes finally bridge the digital divide? My latest story at @technologyreview.com

Cyberthieves hit European Space Agency, stealing hundreds of gigabytes of data "It may be due to a lack of cyber hygiene from ESA staff."

Email credentials of #europeanspaceagency and #NASA employees can frequently be found for sale on dark web forums, says cyber security researcher Clemence Poirier, adding that attacks on space agencies happen almost daily. www.space.com/space-explor...

American Politics is Creating a Rift Between NASA and the ESA NASA is supposed to provide an instrument to help the European Space Agency scan the surface of Venus in powerful detail. American politics and budgeting issues may delay the mission.

A European #Venus mission risks missing its launch window due to ongoing squabbles over the #NASA budget. It's not the first time NASA's changes of priorities put European space ambitions into jeopardy. What should Europe do?

An industrial project in Chile threatens Earth's darkest sky. 28 leading astronomers signed an open letter urging to move it "We might lose the ability to observe about 30% of the faintest galaxies. We are at the point of starting to be able to see details of exoplanet atmospheres, but if the sky gets brighter, we may not b...

The battle over the Atacama pristine night sky continues. Nobel Prize winner Reihnard Genzel has penned a letter urging the Chilean government to stop the construction of a light-polluting plant that threatens to ruin astronomy research. #lightpollution

NASA spacecraft were vulnerable to hacking for 3 years and nobody knew. AI found and fixed the flaw in 4 days "A vulnerability in this software poses a threat to billions of dollars in space infrastructure and the scientific missions they enable."

Plenty #CyberSecurity vulnerabilities reported lately in #space systems. How serious is the situation really?

Struck by a cosmic ray: Galactic particles may have forced a passenger jet to make an emergency landing "Cosmic rays can interact with modern microelectronics and change the state of a circuit."

A cosmic ray could have caused a dangerous altitude loss in an Airbus full of people in October, researcher say. If it sounds surreal, read my story. The accident injured 15 people and forced Airbus to roll out software updates across the fleet.

Europe passes record-breaking space budget while NASA hit with deep cuts Europe has shown its intention to step up amid NASA's funding chaos.

1st European to fly to the moon will be German "No European has ever seen that before."

A German astronaut will be the first European to fly to the #moon with a future NASA-led #Artemis mission. Alexander Gerst, with 362 space days, is the most likely candidate. #europeanspaceagency www.space.com/space-explor...

NASA renews commitment to Europe's life-hunting Mars rover despite Trump budget cuts "These confirmations have been given to us in writing, so this is a very important step."

At the @esa ministerial conference, it has been announced that NASA has recommitted to the European #ExoMars rover project despite Donald Trump's proposal to ax funding for the mission.

Could satellite-beaming planes and airships make SpaceX's Starlink obsolete? "When the Stratomast is flying, all these old satellites are going to be in museums."

Will Europe's flagship space science missions survive NASA's budget cuts? "By the middle of next year, we expect to be in a position to decide on the way forward, with clarity on NASA funding and member state ambition and funding."

Multiple flagship European space missions in peril because of NASA budget cuts pressed by Trump's Administration. Gravitational wave detector #LISA , Venus explore #Envision and the delayed #ExoMars Rover will face shortfalls if NASA withdraws support. www.space.com/space-explor...

What is the chance your plane will be hit by space debris? It's low but, um, never zero.

What are your chances of dying from a #spacedebris strike? Low. But growing. And what about the risk of your plane being delayed because of a satellite falling from the sky? my new story for @techreviewjp.bsky.social www.technologyreview.com/2025/11/17/1...

NVIDIA's H100 GPU Takes Data Centers to Space Could space-based data centers be the answer to Earth's energy and cooling challenges? NVIDIA's H100 GPU is leading the charge in orbit.

NVIDIA and Starcloud have just taken a big step toward moving power-hungry, polluting data centers from Earth to space. Starcloud think they can have a commercial scale data center in orbit in the early 2030s. It does seem to make sense. What do you think? spectrum.ieee.org/nvidia-h100-...

SpaceX Starlink internet isn't fast enough for Ukraine's combat robots The amount of bandwidth provided by SpaceX's Starlink satellites is limiting Ukraine's ability to operate ground robots on the frontline of the nation's war against Russia.

SpaceX #Starlink is indispensible for Ukraine, yet, the internet connectivity it provides isn't fast enough for Ukraine's combat robots, forcing the nation's innovators to look for out-of-the-box solutions.

What Germany’s $41B investment in space could mean for Europe What Germany’s $41B investment in space could mean for Europe

Germany's £35 billion investment into space defence infrastructure over the next five years will be a game-changer for Europe's space sector. Great news for start-ups and SMEs but question marks around Germany's attitude to joint European space projects.
