Snowboarding on Mars

blocks of dry ice slide down crater walls on Mars

If you wanted to go snowboarding on Mars, your board would need to be made of dry ice. A photograph captured by NASA's Mars Reconnaissance Orbiter indicates frozen carbon dioxide (dry ice) may slide down Martian sand dunes on cushions of gas plowing furrows as they go.

The grooves on Martian gullies show relatively constant width with raised banks along the sides. Unlike gullies caused by water flows, on Earth and possibly on Mars, they do not have aprons of debris at the downhill end of the gully. Instead, many have pits at the downhill end where the dry ice blocks may have sublimated in place.

Serina Diniega, a JPL researcher commented: "I have always dreamed of going to Mars but now I dream of snowboarding down a Martian sand dune on a block of dry ice."


Sounds like fun!
