Flight over Korolev Crater on Mars

Flight over Korolev Crater on Mars

Video: 00:02:40 This movie was created using an image mosaic  made from single orbit observations from the High Resolution Stereo Camera (HRSC) on Mars Express, which was first published in December 2018. The mosaic combines data from the HRSC nadir and colour channels; the nadir channel is aligned perpendicular to the surface of Mars, as […]

Podcast: Exploring risky asteroids with Astronomer Marco Micheli

We speak to an astronomer who spends his day studying the motions of ancient asteroids as they roam around the Solar System. If one of them poses a threat, he’ll be one of the first to know, and would provide us with the information we would need to act. Podcast: Exploring risky asteroids with Astronomer […]

Gaia revolutionises asteroid tracking

ESA’s Gaia space observatory is an ambitious mission to construct a three-dimensional map of our galaxy by making high-precision measurements of over one billion stars. However, on its journey to map distant suns, Gaia is revolutionising a field much closer to home. By accurately mapping the stars, it is helping researchers track down lost asteroids. […]
