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...
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."

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

I am having a very awful experience with the #KLM airline. I was supposed to go to South Africa for a SKAO visit on the day of the cyber attacks. I got nowhere.

so, the @KLM duty manager claims there is some
