Earth’s atmosphere: new results from the International Space Station

With ESA’s help, the latest atmosphere monitor on the International Space Station is delivering results on our planet’s ozone, aerosol and nitrogen trioxide levels. Installed last year on the orbital outpost, NASA’s sensor tracks the Sun and Moon to probe the constituents of our atmosphere.

ESA's next science mission to focus on nature of exoplanets

The nature of planets orbiting stars in other systems will be the focus for ESA’s fourth medium-class science mission, to be launched in mid 2028.

Reach for the stars

Human spaceflight and exploration image of the week: ESA astronaut Alexander Gerst begins preflight science measurements.

Sentinels helping to map minerals

The traditional way of mapping Earth’s geology and mineral resources is a costly and time-consuming undertaking. While satellites cannot entirely replace the expert in the field, they can certainly help – as a recent effort in Africa shows.

ESA testing detection of floating plastic litter from orbit

The millions of tonnes of plastic ending up in the oceans every year are a global challenge. ESA is responding by looking at the detection of marine plastic litter from space, potentially charting its highest concentrations and understanding the gigantic scale of the problem.

BepiColombo gets green light for launch site

Europe’s first mission to Mercury will soon be ready for shipping to the spaceport to begin final preparations for launch.

Full house for EDRS

The EDRS–SpaceDataHighway has now begun regularly relaying Earth images from Sentinel-2A, which marks the last of four Copernicus satellites in orbit being brought under the EDRS service.

Voyaging for the Sentinels

Two recent expeditions that took scientists 26 000 km across the Atlantic Ocean have returned critical information to make sure that the Copernicus Sentinel satellites are delivering accurate data about the state of our oceans.

Getting to know Steve

Steve – a strange shimmering ribbon of purple light in the night sky – was discovered in 2016, but now, thanks to ESA’s Swarm mission, more is known about this weird feature of the aurora.

World-first firing of air-breathing electric thruster

In a world-first, an ESA-led team has built and fired an electric thruster to ingest scarce air molecules from the top of the atmosphere for propellant, opening the way to satellites flying in very low orbits for years on end.

Donor star breathes life into zombie companion

ESA’s Integral space observatory has witnessed a rare event: the moment that winds emitted by a swollen red giant star revived its slow-spinning companion, the core of a dead star, bringing it back to life in a flash of X-rays.

Mars Express views moons set against Saturn's rings

New images and video from ESA’s Mars Express show Phobos and Deimos drifting in front of Saturn and background stars, revealing more about the positioning and surfaces of the Red Planet’s mysterious moons.
