Monitoring ocean carbon via satellite

Satellites now play a key role in monitoring carbon levels in the oceans, but we are only just beginning to understand their full potential. Our ability to predict future climate relies upon being able to monitor where our carbon emissions go. So we need to know how much stays in the atmosphere, or becomes stored

How lunar soil could provide heat and energy for habitation

Building a lunar base would be one of the next logical steps in our exploration of the Solar System, but the survival of a future crew depends on access to a reliable source of energy. An ESA Discovery & Preparation study explored how lunar regolith – the dust, soil and rock on the Moon’s surface

3D-printing skin and bone so astronauts might heal themselves on missions

3D printing human tissue could help keep astronauts healthy all the way to Mars. An ESA project has produced its first bioprinted skin and bone samples. These state-of-the-art samples were prepared by scientists from the University Hospital of Dresden Technical University (TUD), part of the project consortium together with OHB System AG as the prime contractor, and life

An electric thruster that ingests scarce air molecules from the top of the atmosphere as propellant for low-orbit satellites

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. ESA’s GOCE gravity-mapper flew as low as 250 km for more than four years thanks to an

“Polar-Sitting” Orbit via Solar Sailing

Tomorrow’s orbit today? This image shows how a large solar sail-equipped satellite could partly offset Earth’s and the Sun’s gravity with the slight but steady pressure of sunlight to hover above the Arctic or Antarctic, enabling continuous coverage of high-latitude regions for climate observation or regional communication services. “Standard space missions employ conventional elliptical ‘Keplerian’
