Mars in 4k

This 4k video pans over the surface of Mars. About halfway through, Valles Marineris can be seen, one of the largest canyons in the Solar System, stretching almost 4000 km across the Martian surface. Towards the end of the video, Olympus Mons appears, a shield volcano almost three times the height of Mount Everest, with an edifice roughly the size of Arizona.
