The European Space Agency (ESA) and the International Committee of the Red Cross (ICRC) have signed a Memorandum of Intent (MoI) to harness space technology for humanitarian assistance worldwide. The partnership will combine ESA's space expertise with ICRC's humanitarian reach to develop space-enabled solutions that can help protect and assist communities affected by disasters and conflicts across Europe and beyond.

The second of the Meteosat Third Generation (MTG) satellites and the first instrument for the Copernicus Sentinel-4 mission are fully integrated and, having completed their functional and environmental tests, they are now ready to embark on their journey to the US for launch this summer.

Ice melting from glaciers around the world is depleting regional freshwater resources and driving global sea levels to rise at ever-faster rates.

According to new findings, through an international effort involving 35 research teams, glaciers have been losing an average of 273 billion tonnes of ice per year since the year 2000 – but hidden within this average there has been an alarming increase over the last 10 years.

Lobster-eye satellite Einstein Probe captured the X-ray flash from a very elusive celestial pair. The discovery opens a new way to explore how massive stars interact and evolve, confirming the unique power of the mission to uncover fleeting X-ray sources in the sky.

The European Space Agency (ESA) and AAC Clyde Space, a New Space company specialising in small satellite technologies, have jointly signed a contract for the first phase of satellite constellation project INFLECION. The initiative will transform Maritime Domain Awareness – the understanding of activities at sea – by enhancing safety, efficiency, compliance, and environmental sustainability in maritime operations.

The European Space Agency (ESA) is ready to guide the ESA/NASA Solar Orbiter spacecraft through its closest encounter with Venus so far.

Today’s flyby will be the first to significantly ‘tilt’ the spacecraft’s orbit and allow it to see the Sun’s polar regions, which cannot be seen from Earth.

Studying the Sun’s poles will improve our understanding of solar activity, space weather, and the Sun-Earth connection.

On 13 and 14 February 2025, the European Space Agency (ESA) celebrated 20 years of supporting space innovation through its ESA Business Incubation Centres (BIC) network. The event in Munich, Germany, brought together entrepreneurs, successful space companies, experts and policymakers.

Watch the latest updates on ESA’s Fly! Feasibility Study with Daniel Neuenschwander, ESA Director of Human and Robotic Exploration, John McFall, Member of the ESA Astronaut Reserve & Fly! Subject Matter Expert, Jerome Reineix, Fly! Study Manager, and Alessandro Alcibiade, Fly! Flight Surgeon.

Announced in November 2022 during the Ministerial Council held in Paris, France, this unique and groundbreaking study is aimed at understanding and challenging the limitations posed by physical disabilities to human spaceflight. Concluded in late 2024, the Fly! Feasibility Study successfully demonstrated it is technically feasible to fly someone with a physical disability, like John’s, on a six-month mission to the International Space Station as a fully integrated crew member. It underpinned the desire to ensure that space exploration is not limited by physical constraints and that every individual can contribute to our collective understanding of the cosmos and of the benefits of spaceflight for life on Earth.

The end of the feasibility study marks the start of the next phase: Fly! Mission Ready . This is an essential step to carry out the first long-term mission for an astronaut with a physical disability.

In a first for space cuisine, ESA project astronaut Sławosz Uznański-Wiśniewski will bring pierogi, the traditional Polish dumplings, to the International Space Station during the upcoming Axiom Mission 4.

Launched just two months ago and still in the process of being commissioned for service, the Copernicus Sentinel-1C satellite is, remarkably, already showing how its radar data can be used to map the shape of Earth’s land surface with extreme precision.

These first cross-satellite ‘interferometry’ results assure its ability to monitor subsidence, uplift, glacier flow, and disasters such as landslides and earthquakes.

The European Space Agency (ESA) has jointly signed a contract with Thales Alenia Space to develop Element #2 of its High-throughput Digital and Optical Network (HydRON), an advanced laser-based satellite system that will transform the way we communicate in space. This phase will establish a satellite collector in low Earth orbit (LEO), capable of connecting different orbital layers using cutting-edge optical technology.

After years of meticulous development, ESA’s next Earth Explorer satellite, Biomass, is ready to be packed up for transport to Europe’s Spaceport in French Guiana, where it will launch aboard a Vega-C rocket this spring.

Before final preparations and shipment, media representatives had the exclusive opportunity today to see the satellite up close in the cleanroom at Airbus’ facilities in Toulouse, France.

Today we mark the International Day of Women and Girls in Science. Join us in a journey around Europe with EIROforum organisations to discover the brilliant talents who are shaping the future of science and technology, and dive deeper into the story of a European Space Agency young professional making her way in space. 

Euclid, the European Space Agency’s dark Universe detective, has made an astonishing discovery – right in our cosmic backyard.

Optical technology has the potential to revolutionise the field of positioning, navigation and timing. To drive the development of this technology, ESA has signed a contract with a consortium of European companies that will conduct a definition study (Phase A/B1) and associated critical technology predevelopment.

This is the first step toward a potential in-orbit demonstrator for optical time synchronisation and ranging (OpSTAR) that will be proposed at the ESA Council at Ministerial Level in November 2025, to validate intersatellite optical links before future use in operational satellite navigation systems.
