Mars, Mapped 

The USGS has just released a gorgeous new geologic map of Mars, combining data from four separate spacecraft to paint a rainbow-like spectrum of terrain and texture upon the red planet.

See those four bulges on the left side of the spherical projection? Each of those four mountains, Olympus Mons, Ascraeus Mons, Arsia Mons, and Pavonis Mons, are taller than any mountain on Earth, including Mauna Kea (which rises more than six miles from the ocean floor).
