Scientists have confirmed that if you can find a flight, you could ski on Mars.
Well, sort of.
Researchers at the Massachusetts Institute of Technology have confirmed the existence of snow on Mars.
The snow is made of microscopic pieces of frozen CO2, instead of water, and are about the size of a red blood cell. In the south of the planet they are thought to be even smaller.
As a result the snow appears more like a fine fog over the surface of the planet.
It's been thought for some time that snow may exist on the planet, but its size and form hadn't been known until now.
The mission was funded by the Radio Science Gravity investigation of the NASA Mars Reconnaissance Orbiter mission.
