Happy Earth Day, 22 April – a global call to act and protect our planet. At the European Space Agency, that action begins in orbit, where satellites deliver a continuous, global view of Earth and track environmental change. Working with partners, ESA turns this stream of data into actionable information through its FutureEO programme, helping governments and communities respond faster and more effectively to climate-driven risks.
The European Space Agency Plato mission has successfully completed a series of tough tests under space‑like conditions. With this accomplishment, the spacecraft is on track to lift off in early 2027 and begin its search for terrestrial planets.
The NASA/ESA Hubble Space Telescope looked at a scene it first captured in 1997 in honour of 36th anniversary: a small portion of a star-forming region about 5000 light-years away in the constellation Sagittarius, known as the Trifid Nebula. The image shows changes over incredibly short timescales and instills a sense of awe and wonder about our ever-changing Universe.

Three Earth observation satellites, developed by the European Space Agency (ESA) with European partners, and due to launch later this year, have completed their functional and environmental tests and are ready to travel to the European spaceport in French Guiana. But first, journalists were invited to have one last look.
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.
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.
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.
Today, at 17:07 local time on 10 April (01:07 BST/02:07 CEST 11 April), NASA’s Orion spacecraft and its crew splashed down safely in the Pacific Ocean, marking the end of the Artemis II mission. ESA’s European Service Module powered this historic mission that took four astronauts around the Moon and back for the first time since Apollo 17 in 1972.
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.

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

The European Space Agency has achieved a European first with Celeste, successfully transmitting a navigation signal from low Earth orbit, following the launch of the mission’s first satellites on March 28.

Lasers could one day steer solar sails and adjust a satellite’s position in outer space, thanks to graphene. An experiment on a gravity rollercoaster ride showed how this innovative material has the potential to revolutionise propulsion beyond Earth.
On 6 April 2026, NASA’s Artemis II Mission, powered by ESA’s European Service Module (ESM), brought humans further than ever before.
