Four papers were recently published in Science on the history of water on Mars using data collected by NASA’s Phoenix Lander.  Some of the discoveries discussed include:  during Mar’s winter it snows frequently at night, the clouds there are similar to Earth’s cirrus clouds, a layer of ice lies 2-7 inches under the soil,  liquid water helped shape the surface of Mars, and the snow falling on Mars is similar to the low-moisture ice crystals that fall in the Arctic called diamond dust.

What do these findings mean?  They provide us with a very different picture of Mars than the view that scientists previously held.  They give us a glimpse of Mar’s past where life potentially could have thrived.  For more on these papers, see Science Daily.
