Metre-sized meteoroid 2026 RW1 (previously known as CERNQ52) hit the ocean off NW Australia on Sunday afternoon - but the impact was forecast roughly six hours in advance, using ESA’s Meerkat automated system for predicting imminent impactors! neo.ssa.esa.int/imminent-imp...

A historic night for European spaceflight. Huge congratulations to Daniel Metzler and the entire Isar aerospace team on reaching orbit with Spectrum 🚀 from continental Europe. www.esa.int/Enabling_Sup...

What do you know about Copernicus Sentinel-3? Since 2016, Sentinel-3 has been monitoring oceans, land, ice & the atmosphere, helping us understand climate change. Ahead of Sentinel-3C’s launch, discover how the mission contributes to understanding our changing planet: www.esa.int/Applications...

How Sentinel-3 tracks climate change

Copernicus Sentinel-3 is one of the most diverse missions for measuring and monitoring Earth’s climate systems. It captures a breadth of data about the environment and has contributed substantially to...

Our warning system Meerkat has detected a new small meteoroid impacting the Earth in the next hour. Don't be afraid! It is just around 1 metre in size and it will just make a great show in the sky.

🫶 And there were none... Tango danced its final dance and reentered the atmosphere at 23:30:31 CEST. The signal from the spacecraft via Kourou was lost forever 13 minutes earlier. But once more: the airborne observation campaign has reported success - stay tuned! blogs.esa.int/rocketscienc...

💃 Samba has danced its final dance and reentered the atmosphere at 23:39:38 CEST. The final signal from the spacecraft via Kourou was lost for the last time 13 minutes earlier. But, good news: the airborne observation campaign has reported success - stay tuned! blogs.esa.int/rocketscienc...

☀️💶 Just one big solar storm can cost Europe tens to hundreds of billions of euros according to the new socio-economic impact report published by the European Commission. Operational space weather services will make a critical difference. defence-industry-space.ec.europa.eu/study-impact...

LIFTOFF! 🚀 Ariane 6 #VA270, launching MTG-I2, completing Europe's Meteosat constellation.

Success! ✅ MTG-I2 is on its way to geostationary orbit. After acquiring signal, the satellite has been confirmed healthy. 🔗 esa.int/Newsroom/Press_Releases/MTG-I2_completes_Europe_s_latest_weather_trio
