Good morning / goedemorgen ESA ESTEC! It’s the last #ESAOpenDay of 2025, are you ready?

The first day of the ESTEC Open Days is done and we had so much fun speaking to all of our visitors today! 🚀 If you're visiting us tomorrow, don't forget to pass by, have a chat and grab some goodies! We're the ones with the rockets 😉

What an honour to attend Countdown to COP30: Mobilising Action for Climate and Nature. For decades, I have deeply admired His Majesty King Charles for his unwavering commitment to environmental advocacy – consistently championing sustainability and the protection of our planet

Let's take a look back at when Cyclone Errol was heading towards the coast of Western Australia on 16 April. In this @CopernicusEU Sentinel-3 image, the typical pinhole eye – a small, well-defined eye often associated with powerful and rapidly intensifying tropical cyclones –

Everyone deserves to safely share the road. Learn how Waymo is working to make our roads safer.

🛰️ The biggest spacecraft to cruise to Mars will need a powerful push to enter orbit. @esa’s Earth Return Orbiter will rely on the thrust of its Orbit Insertion Module to perform this critical manoeuvre. 🎊 A year of quiet triumphs: https://t.co/mjpgCzc3IO

🚀It’s almost time to shape the next chapter of Europe’s journey in space. The European Space Agency’s Council Meeting at Ministerial Level, known as #CM25, will take place in Bremen, Germany, on 26 and 27 November 2025. This high-level event brings together ministers from

🆕Researchers combed through images from ESA's #MarsExpress & #ExoMars spacecraft to find 1039 swirling dust devils 🌪️ Using these dust devils to track raging winds on Mars, their findings include that the strongest winds blow much faster than we thought! Read more 👉

Satellites have captured the largest ocean swells ever measured from space, averaging nearly 20 metres high🌊 In a new study, scientists used data from @esaclimate’s Sea State project and the SWOT mission to improve wave models and better understand how these long waves travel

🛰️ Rehearsing for Sentinel-6B’s early days in space Mission control at ESOC is getting ready for the launch of Europe’s latest sea-level monitoring satellite. The campaign is designed to test their ability to deal with issues, adapt the timeline, and operate under stress.

☄️ #3I/ATLAS comet update! On 3 October, our ExoMars Trace Gas Orbiter (TGO) turned its eyes towards interstellar comet 3I/ATLAS as it passed close to Mars. Together with Mars Express, ExoMars TGO had the closest view of the comet of all of our spacecraft. It looked towards the

Check out the first data from the METimage instrument on board @eumetsat's MetOp-SG-A1 satellite! This advanced instrument observes clouds, land, sea and ice, providing key insights into weather forecasting, nowcasting, and climate monitoring. https://t.co/OKP86LYUO0 📸 EUMETSAT

🛰️ Europe’s largest vacuum chamber, the Large Space Simulator located at our test centre in the Netherlands, routinely reproduces space conditions on Earth to test spacecraft before they fly into orbit. 🖥️ The facility is complex, and the current process of training a new

✨ NGC 6951: a starbusting spiral galaxy. Nestled away at its core, NGC 6951 has another remarkable feature: a white-blue ring that encloses the very heart of the galaxy. The dense gas in this starburst ring is the perfect environment to churn out an impressive number of

It's official: @CopernicusEU's Sentinel-1D ride to space is scheduled for 4 November at 22:03 CET (21:03 UTC).

Asteroid 2025 TF flew over Antarctica at 00:47:26 UTC ± 18 s on 1 October, coming as close as 428 ± 7 km to Earth’s surface. This is a similar altitude to the orbit of the International Space Station, and one of the closest approaches ever recorded. https://t.co/WZZHWLqyit
