This radar image from the Copernicus Sentinel-1 mission captures Buenos Aires, the capital of Argentina, the surrounding countryside and the Rio de la Plata estuary.

Zoom in to explore this image at its full resolution.

This is a composite of three Sentinel-1 acquisitions taken in January, March and May this year, with each image assigned to a different colour channel (blue in January, green in March and red in May). As the environmental changes on the ground created a significant ‘backscatter’ reflection of the radar signal, they show up as bright shades that correspond to changes across the seasons.

The second generation of Galileo, Europe’s satellite navigation constellation, is being built. These satellites will feature reconfigurable payloads, provide more robust and reliable positioning, navigation and timing, enable new services and add new capabilities to the constellation.

One of these capabilities, intersatellite links, will allow the satellites to communicate with one another in orbit. After going through extensive testing, the intersatellite link antennas are ready to be integrated into the satellites.

ESA astronaut Sophie Adenot joined ILA Berlin 2026 live from the International Space Station for a special in-flight conversation on life and work in orbit, Europe's ambitions in human spaceflight. The call featured ESA Director General Josef Aschbacher and ESA Director of Human and Robotic Exploration Daniel Neuenschwander, as well as ESA astronauts Alexander Gerst and Matthias Maurer, as well as Thomas Reiter, Head of the Space and Security Department in the Federal Ministry of Research, Technology and Space (BMFTR) and former ESA Astronaut.

From strategic discussions on autonomy and resilience to an in-flight call with ESA astronaut Sophie Adenot, ESA's second day at ILA Berlin International Airshow 2026 highlighted the wide-reaching value of space for Europe now and in the future.

On 10–11 June, representatives from European Space Agency (ESA) Member States met in Tenerife to make far-reaching decisions about the future of ESA’s Science Programme. Their decisions to extend current missions and adopt the next ‘fast-class’ mission, Arrakihs, underscores European leadership in, and long-term commitment to, space science.

The eighth flight of Europe’s rocket Ariane 6 will have a bigger boost: the P120C solid-propellant rocket motor, used as Ariane 6 booster so far, has been upgraded. The new P160C flying on Ariane 6 flight VA269 offers 10% more performance to orbit.

P160C was developed by Europropulsion under contract from ArianeGroup and Avio. Just like P120C, P160C comes in three main parts, its structure is made in Italy, the rocket engine nozzle in France and the igniter in Norway.

After being shipped to Europe’s Spaceport in French Guiana, the P160C boosters are loaded with 14 tonnes more fuel
