Meet the voices astronauts hear in space. At ESA’s European Astronaut Centre in Cologne, Germany, the EUROCOM team is the link between crew and ground, guiding astronauts like ESA astronaut Sophie Adenot through their daily work on the International Space Station. Join us as EUROCOM expert Andreas Orth explains how complex operations are translated into clear, real-time communication and what it means to be the one voice connecting Earth and orbit.

In April, Galileo marked a step forward with the deployment of a new signal component, known as E5a Quasi Pilot, on 12 satellites of Europe’s satellite navigation constellation. This upgrade makes Galileo signals easier to access, particularly on emerging mass-market, low-power devices used for Internet of Things and smart city applications.

Sophie is halfway through the εpsilon mission onboard the ISS, and she has already accomplished so much. Between hundreds of hours of scientific research and thousands of photographs taken from space, she has taken the time to share many unforgettable moments with us — inspiring millions along the way on social media.

On the 17th of June Ariane 6 flight VA269 soared to orbit from Europe's Spaceport in French Guiana. The latest generation of Europe's largest and most powerful rocket launched 36 satellites for Amazon's Leo constellation. 

The debut of the four new boosters based on the P160C solid-propellant rocket motor allowed 36 satellites to be launched, four more than the two Leo launches Ariane 6 had delivered before. 

 Ariane 6 is Europe’s heavy-lift launcher and a key element of ESA’s efforts to ensure autonomous access to space for Europe’s citizens. The new P160C boosters increase considerably performance, payload capacity and competitiveness, allowing for more satellites to be launched, further elevating the future of Europe.

The European Space Agency Council has approved the appointment of two new directors: Christine Klein as Director of Controlling, Finance and Operational Procurement, and Jean-Luc Trullemans as Director of Strategy, Legal and External Affairs.

ESA Impact: a look at ESA’s spring milestones

The European Space Agency’s Mars Express has captured part of Mars’s Mamers Valles: a fascinating valley system speckled with brief, tornado-like whirlwinds known as dust devils.

Researchers have confirmed a new class of objects within our Milky Way galaxy: survivors called 'bulge fossil fragments.' Terzan 5 is the prototype of these remnants of our galaxy's early formation. Using the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescopes researchers have shown that Terzan 5 is not a globular star cluster as it was once classified. Instead, it is something much odder and rarer.

Image:

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.

On the right-hand side of the image, the metropolitan area of Buenos Aires is visible in light grey. The area has a population of more than 16 million people and lies at 25 m above sea level. The urban areas were largely unchanged between January and May, hence the lack of colour in this part of the image. Other towns, such as Luján and Junin, are also visible as smaller patches of grey west of the capital.

The blue areas correspond to surface changes such as choppy water, captured in January, which is mid-summer in Argentina. The rivers, deltas and open water are mainly coloured in either dark blue, purple or black. Winds and rough sea conditions during both January and May mean that the Rio de la Plata estuary, east of Buenos Aires, appears purple (a mix of blue in January and red in May). The Paraná river meanders through wetlands on the left of the image before flowing into the Rio de la Plata. The Uruguay river is also seen flowing from the north into the estuary.

To the west of Buenos Aires, agricultural fields and the Argentinean Pampas dominate the landscape. The green tint is due to significant ‘backscatter’ reflection of the radar signal in this area during the capture in March. Since this period is late summer in Argentina, it likely denotes growth of major crops such as soy and corn.

At the top of the image, a large area north of the Paraná river, in Entre Ríos province, appears in vivid red – the channel assigned to ground change in May, which is late Autumn in Argentina. It is likely that this is due to natural vegetation growth caused by seasonal rains during that period. This is when the areas of exposed grassland come back to life following the long, dry summers.

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.

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.

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.
