Rosetta — spacecraft, shown live in Cosmoscope, a real-time 3D map of the universe.
Rosetta chased down and orbited a comet, dropped the Philae lander onto its surface, then gently crash-landed itself to end a twelve-year odyssey.
Cosmoscope draws Rosetta on its real trajectory, from mission ephemeris rather than an artist's impression. Open the live 3D view to see where Rosetta 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.
