Come on the Journey To Discover What The Inside of an Impact Crater on Mars Looks Like

NASA's Mars Reconnaissance Orbiter captured the stunning shot of the "enigmatic" mounds on the floor of a crater in Bosphorous Planum.

00:00Strange mounds on Martian craters floor have scientists scratching their heads.

00:08NASA's Mars Reconnaissance Orbiter captured the stunning shot with its

00:12high-rise camera. The odd mounds are in an unnamed impact crater located in an

00:16area south of the Red Planet's Canyon region, Valles Marineris. NASA isn't sure

00:21how they formed, asking are they products of sublimation and crater

00:25inversion. Sublimation is the process where a solid goes directly to a gas,

00:29kind of like watching dry ice disappear on Earth. When cracks occur on Mars,

00:33underground ice sublimates along the surface, altering the terrain. NASA says

00:37crater inversion is seen on both Earth and Mars and is caused when erosion

00:41strips away the surrounding terrain. Inverted craters stick up above the

00:45ground instead of being a depression like most other craters.
