The Guinness Book of World Records has awarded JAXA the record for the lowest altitude by an Earth observation satellite. During its mission from 2017 to 2019, the Super Low Altitude Test Satellite reached a suitably super-low altitude of 167.4 km.

ESA has successfully launched its Cheops telescope on a mission to make detailed follow-up studies of distant exoplanets discovered by earlier space-faring telescopes, such as Kepler and TESS.

A comprehensive new study has tracked long-term ice loss in Greenland, and found that the Ice Sheet has lost 3.8 trillion tonnes of ice since 1992 – and the annual rate is rising faster than previously expected.

ESA has commissioned the world's first mission to recover a piece of space debris in orbit. At the end of November, the Ministerial Council consortium awarded a service contract to a consortium for the ClearSpace-1 mission to launch in 2025.

Astronomers go to great lengths to find the quietest, darkest corners of the night sky, but a new breed of satellites like those of SpaceX's Starlink project threaten to ruin the views in very damaging ways. And the problems don't end there.

Central to SpaceX's mission of making rocket launches as cheap as possible is recovering and recycling as many components as possible, and it today took another significant step toward this aim, flying a recovered payload fairing for the first time.

Virgin Orbit has revealed plans for the first commercial satellite mission to Mars, where a new breed of tiny probes could help study the Red Planet.

The Hero rescue beacon is about the size of a pepper grinder, and it costs nothing to use.

ESA plans to launch the first Earth observation satellite incorporating artificial intelligence (AI) in a few months.

ESA has been forced to reposition its Aeolus satellite to avoid a collision with a member of SpaceX’s Starlink mega constellation.

NASA has released images and footage of Hurricane Dorian, as it continues its menacing advance across the Atlantic Ocean.

ESA has released a tool that lets space enthusiasts track probes in real time as they communicate with ground stations on Earth.
