Mars Express — spacecraft, shown live in Cosmoscope, a real-time 3D map of the universe.
ESA’s first Mars mission has circled the Red Planet for over two decades, radar-sounding for buried water and imaging the surface in 3D.
Cosmoscope draws Mars Express on its real trajectory, from mission ephemeris rather than an artist's impression. Open the live 3D view to see where Mars Express is right now, how far it has travelled from the Sun, and how long its radio signal takes to reach Earth. Scrub the timeline to replay the route that took it there.
