A newly devised procedure to de-ice Euclid's optics has performed significantly better than hoped. Light coming in to the visible ‘VIS’ instrument from distant stars was gradually decreasing due small amounts of water ice building up on its optics. Mission teams spent months devising a procedure to heat up individual mirrors in the instrument’s complex optical system, without interfering with the finely tuned mission’s calibration or potentially causing further contamination. After the very first mirror was warmed by just 34 degrees, Euclid's sight was restored.

A fresh, icy crust hides a deep, enigmatic ocean. Plumes of water burst through cracks in the ice, shooting into space. An intrepid lander collects samples and analyses them for hints of life.

Imagine being able to ask a chatbot, “Can you make me an extremely accurate classification map of crop cultivation in Kenya?” or “Are buildings subsiding in my street?” And imagine that the information that comes back is scientifically sound and based on verified Earth observation data.

Air pollution is the largest environmental health risk in Europe and significantly impacts the health of the European population, particularly in urban areas.

ESA’s Gaia space telescope has further disentangled the history of our galaxy, discovering two surprising streams of stars that formed and wove together over 12 billion years ago.

ESA has signed contracts with several European companies for an overall amount of € 233 million to develop Genesis and a LEO-PNT demonstrator, two new missions within the FutureNAV programme that will keep Europe at the forefront of satellite navigation worldwide.

A few layers of water ice – the width of a strand of DNA – are starting to impact Euclid’s vision; a common issue for spacecraft in the freezing cold of space, but a potential problem for this highly sensitive mission that requires remarkable precision to investigate the nature of the dark Universe. After months of research, Euclid teams across Europe are now testing a newly designed procedure to de-ice the mission's optics. If successful, the operations will validate the mission teams’ plan to keep Euclid’s optical system as ice-free as possible for the rest of its life in orbit.

Astronomers have created the largest yet cosmic 3D map of quasars: bright and active centres of galaxies powered by supermassive black holes. This map shows the location of about 1.3 million quasars in space and time, with the furthest shining bright when the Universe was only 1.5 billion years old.

The shoebox-sized Milani CubeSat, which will perform close-up mineral prospecting of the Dimorphos asteroid, is ready for delivery to ESA’s Hera asteroid mission for planetary defence. The spacecraft will carry Milani and a second CubeSat, the Juventas radar imaging spacecraft for probing into the target asteroid, which together will be ESA’s first CubeSats to operate in deep space.

Climate change exacerbates droughts by making them more frequent, longer, and more severe. This can have a wide range of impacts on the environment, agriculture, ecosystems and communities including water scarcity, crop failure and food shortages.

The European mission control centre near Munich, Germany, is set to undergo a transformation into a Moon mission control centre, tasked with supporting operations for missions to a lunar space station, the lunar surface and beyond.

ESA’s Arctic Weather Satellite has passed its environmental test campaign with flying colours – meaning that the satellite has been declared fit for liftoff and its life in the harsh environment of space.

After more than 6 months on the International Space Station, ESA astronaut Andreas Mogensen returned to Earth, marking the end of his Huginn mission. It was his second mission to the Space Station and his first long-duration, where he was the pilot of Crew-7, which consisted of Jasmin Moghbeli (NASA), Satoshi Furukawa (JAXA), and Konstantin Borisov (Roscosmos).

ESA, on behalf of the European Commission, has signed a €12 million contract with Leonardo S.p.A (Italy) and Istituto Nazionale di Ricerca Metrologica to design and develop a new ultra-precise atomic clock technology for Galileo.
