Safety First 🌙 Good news! NASA’s Webb Telescope has officially ruled out a potential 2032 lunar impact for asteroid 2024 YR4. Thanks to Webb’s extreme sensitivity, we now know it will safely pass the Moon, giving future astronauts and satellite operators peace of mind. 🛡️ #NASA #JWST #SpaceSafety 1/2

📣It's tiiiiiime!

The European #SpaceWeather Week #ESWW2025 in Umeå 🇸🇪 has kicked off today!

☀️✨🍭🌍📡🛰️⚡️✈️🚀👨‍🚀

There's lots going on for ESA and the ESA SWE Service Network at ESWW with contributions across many sessions.
We'll be sharing some highlights over the coming week👀

🌍🇪🇺#EUSST closely monitors the re-entry of 🇷🇺 #Cosmos482 onto Earth strengthening the case for more responsible behaviour in space & the upcoming EU #SpaceAct — for better space safety and resilience.

🇪🇺 leads by example and capability.

Safety first! As a precaution during a recent inspection of the Zvezda service module, NASA directed Crew-12 and astronaut Chris Williams to enter "safe haven" mode inside the SpaceX Dragon spacecraft. They have since returned to normal operations. #SpaceSafety #ISS

2.04 km: the razor-thin miss distance as OBJECT AE and TOM-2 barrel past each other in orbit, both unable to steer. Their speeds? Several km/s. This is why we monitor 29,422 orbiting objects; debris can't adjust course. See more at https://orbitalradar.com/conjunctions. #OrbitalRadar #SpaceSafety

From high frequencies near the Sun to low frequencies at Earth, NASA missions tracked a record solar radio burst across the solar system. 🌌 This breakthrough helps us map the journey of solar storms before they hit our planet. 🌍 #NASA #SolarSystem #SpaceSafety

Why does Smile matter? By studying the interaction between the Sun and our magnetic shield, scientists will create better models of our space environment. This could ultimately help keep our astronauts and vital space technologies safe for decades to come. 🛡️✨ #SpaceSafety #STEM

New analysis of NASA’s DART mission shows boulders ejected from Dimorphos formed clustered streams and carried more momentum than expected. The results raise concerns for asteroid deflection planning.

Giant space 'boulders' unleashed by NASA's DART mission aren't behaving as expected, revealing hidden risks of deflecting asteroids
Debris released from the asteroid Dimorphos during NASA's DART mission has a higher momentum and less random distribution than expected, which "changes the physics we need to consider when planning th...
