Lucy — spacecraft, shown live in Cosmoscope, a real-time 3D map of the universe.
Lucy is on a twelve-year tour to visit a record number of Trojan asteroids — fossils of the planet-building era, frozen along Jupiter’s orbit.
Cosmoscope draws Lucy on its real trajectory, from mission ephemeris rather than an artist's impression. Open the live 3D view to see where Lucy 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.
