Here’s what snow looks like on Mars and it’s nothing like on Earth


The Bay Area is in the middle of a frigid
cold snap, driven by a blast of icy Arctic air.

But winter temperatures on Mars can drop over 200 degrees lower. Amid these bitterly cold conditions, the Red Planet develops ice, frost and — at its coldest extremes — several feet of snow.

This isn’t water-based snow, like what’s piled up in California’s
Sierra Nevada. Because the Red Planet is so dry and so cold, scientists don’t think that such snowflakes would make it down to the surface.

But another kind of snow, made up of carbon dioxide, does.

“Enough falls that you could snowshoe across it,” said Sylvain Piqueux, a Mars scientist at NASA’s Jet Propulsion Laboratory.
