Shrinking ice is arguably one of the most visible indicators of climate change – particularly in the Arctic. However, a European Space Agency-funded study used information from satellites to show that Antarctica is now experiencing similar dramatic changes, with profound consequences for key plankton species that underpin the region’s marine food web.

Each year the European Space Agency (ESA) invites small- and medium-sized enterprises (SMEs) and midcaps to share their views and give feedback about topics which affect their work in the space sector.

An SME Forum occurs as part of the SME and Midcap Days on 8–9 June 2026 at ESA Headquarters in Paris, France. This is preceded by an online preparatory SME Forum in April and May.

Actionable data from space could be delivered in seconds in the future, thanks to progress towards the European Space Agency’s (ESA) faster and more secure laser communications network, HydRON. At the 41st Space Symposium in Colorado Springs, Canadian satellite communications company Kepler was awarded a contract to lead the next phase in the project’s evolution. 

Noticeable change on Mars often takes millions of years – but the European Space Agency’s Mars Express has captured a blanket of dark ash creeping across the planet in just decades.

The first‑of‑its‑kind ship‑to‑ship call between astronauts on deep‑space and low Earth orbit missions.On 7 April, the Artemis II crew of NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, together with CSA (Canadian Space Agency) astronaut Jeremy Hansen, spoke with Expedition 74 astronauts Chris Williams, Jack Hathaway and Jessica Meir of NASA, and ESA (European Space Agency) astronaut Sophie Adenot aboard the International Space Station.

Since July 2025, the European Space Agency’s pair of Proba-3 satellites has already created 57 artificial solar eclipses. So far, the mission has collected more than 250 hours of high-resolution videos of the Sun’s atmosphere, called the corona. That’s the same amount of observing time as about 5000 total solar eclipse campaigns carried out on Earth.  

But the science is even more exciting. For the first time we can carefully track how material from the Sun moves through the inner corona, where space weather is born. The first results, recently published in The Astrophysical Journal Letters, show that solar wind structures in the inner corona can travel three to four times faster than scientists thought. 

Artemis II completed a 10-day journey around the Moon, carrying humanity farther into space than it has gone in over 50 years.

ESA played a critical role in the mission’s success. The European Service Module powered and sustained Orion throughout the journey, providing propulsion, power, water and breathable air for the crew.

Mostly built with contributions from 13 ESA Member States—Germany, Italy, France, Switzerland, the Netherlands, Belgium, Spain, Norway, Denmark, Sweden, Austria, the United Kingdom and Luxembourg—the module represents Europe’s strength in international cooperation.

Looking ahead, ESA will continue to deliver on its commitments to the Artemis programme while advancing
