Video: 01:08:00 Watch the replay of our Hera mission Mars flyby event. On 12 March 2025, ESA’s Hera mission came to within 5000 km of the surface of the red planet and 300 km of Mars’s more distant and enigmatic moon Deimos. During this flyby, Hera performed observations of both Mars and the city-sized Deimos. […]
While performing yesterday’s flyby of Mars, ESA’s Hera mission for planetary defence made the first use of its payload for scientific purposes beyond Earth and the Moon. Activating a trio of instruments, Hera imaged the surface of the red planet as well as the face of Deimos, the smaller and more mysterious of Mars’s two […]
High above the Arctic Circle, on the rugged terrain of Andøya, three ESA radionavigation engineers take a rare moment to unwind with a game of shuffleboard. Outside, sheep graze under the shimmering northern lights, a serene backdrop to their demanding mission: test how navigation technologies withstand interference signals. With 100TB of data collected over 5 […]
European scientists are asking volunteers to lie down on a waterbed for 10 days as part of a pioneering dry immersion study to recreate some of the effects of spaceflight on the body. To source
Video: 00:03:21 Meet Hera , our very own asteroid detective. Together with two CubeSats – Milani the rock decoder and Juventas the radar visionary – Hera is off on an adventure to explore Didymos, a double asteroid system that is typical of the thousands that pose an impact risk to planet Earth. In September 2022 NASA’s […]
The European Space Agency has unveiled the ESA Space HPC, a new resource for space in Europe. ESA Director General Josef Aschbacher was joined by ESA Council Chair Renato Krpoun and ASI president Teodoro Valente to cut the ribbon at ESA’s establishment in Italy, ESRIN. To source
Help us uncover the secrets of the Sun! Our Solar Orbiter spacecraft has been watching the Sun since February 2020. With five years’ worth of data waiting to be explored, it’s time to dig in. The new ‘Solar Radio Burst Tracker ’ Zooniverse project is ready for you. To source
Video: 00:02:43 On 12 March 2025 ESA’s Hera spacecraft for planetary defence performs a flyby of Mars. The gravity of the red planet shifts the spacecraft’s trajectory towards the Didymos binary asteroid system, shortening its trip by months and saving substantial fuel. This is a simulation of that flyby, with closest approach to Martian moon […]
Video: 00:01:36 On Wednesday 12 March 2025 ESA’s Hera spacecraft for planetary defence performs a flyby of Mars. The gravity of the red planet shifts the spacecraft’s trajectory towards its final destination of the Didymos binary asteroid system, shortening its trip by months and saving substantial fuel. Watch the livestream release of images from Hera’s […]
Join us live for a star-studded event this Thursday , as scientists working on ESA’s Hera mission for planetary defence release the mission’s first scientific observations beyond the Earth-Moon system, following its imminent flyby of Mars. To source
