ExoMars Trace Gas Orbiter — spacecraft, shown live in Cosmoscope, a real-time 3D map of the universe.
TGO hunts for trace methane and other gases that might hint at life or active geology hidden beneath the Martian surface.
Cosmoscope draws ExoMars Trace Gas Orbiter on its real trajectory, from mission ephemeris rather than an artist's impression. Open the live 3D view to see where ExoMars Trace Gas 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.
