I was pleased to welcome Director General @AschbacherJosef and our @esa partners to NASA Headquarters today. As we move forward with our return to the Moon, the European Space Agency remains a key partner across much of NASA’s portfolio. Their contributions will be important as we build a sustained lunar presence and prepare for missions beyond.



The first official images from @eumetsat's MTG-S1 satellite are in👀 These images from 15 December 2025 show Earth’s atmosphere in terms of temperature and humidity — data that will support more accurate weather forecasting, especially for nowcasting rapidly evolving storms. How to read them: In the temperature image (left), warmer land surfaces appear red and colder appear blue. In the humidity image (right), blue indicates higher humidity, while red marks drier regions. esa.int/Applications/O… 📸 @Thales_Alenia_S, @OHB_SE, @esa and @eumetsat.







We have a mission! Both HydroGNSS satellites have sent their first signals 📡 HydroGNSS is an @esa Scout mission under FutureEO: compact in size, but built to deliver big science insights into Earth’s water cycle💧: esa.int/Applications/O…



🚀 It's launch day (again😉) for @ESA_EO's HydroGNSS satellite along with @IrideSpazio and @iceye_global satellites. Tune in today, 28 November, from 18:01 GMT/19:01 CET, to watch the liftoff live on #ESAwebTV. 📷 watch.esa.int/two 🔗 esa.int/Applications/O…


What happens in the Arctic does not stay in the Arctic. What happens in the Arctic shapes our climate, influences our economies, and has an impact on our security. Today, the Arctic faces renewed global interest. It must adapt – and space can play a decisive role in that adaptation. From orbit above the Arctic, one can monitor two oceans, three continents, and the entire Northern Hemisphere simultaneously. This is precisely why today I signed a Letter of Intent between @esa and the Kingdom of Norway to establish an ESA Arctic Space Centre in Tromsø. #msdynmkt_trackingcontext=2d6be264-8661-48c7-a469-deb883e80000" target="_blank" rel="nofollow noopener">esa.int/About_Us/Corpo…
