Lunar Reconnaissance Orbiter — spacecraft, shown live in Cosmoscope, a real-time 3D map of the universe.
LRO has mapped the Moon in dazzling detail, scouting future landing sites and even spotting the old Apollo gear still sitting on the surface.
Cosmoscope draws Lunar Reconnaissance Orbiter on its real trajectory, from mission ephemeris rather than an artist's impression. Open the live 3D view to see where Lunar Reconnaissance Orbiter 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.
