Overview Mars is a cold desert planet with no liquid water on its surface. But in the Martian arctic, water ice lurks just below ground level. Discoveries made by the Mars Odyssey Orbiter in 2002 show large amounts of subsurface water ice in the northern arctic plain. The Phoenix lander targets this circumpolar region using a robotic arm to dig through the protective top soil layer to the water ice below and ultimately, to bring both soil and water ice to the lander platform for...

Even in the clearest, bluest sky on Earth, there is still water vapor in our atmosphere. If you could condense all the water vapor out of the atmosphere above you, it would form a layer of water two centimeters deep. On Mars today, there is also water vapor in the atmosphere but it would create a layer just 10 micrometers thick.

When NASA's Phoenix Mars Lander descends to the surface of the Red Planet on May 25, few will be watching as closely as the men and women who have spent years planning, analyzing and conducting tests to prepare for the dramatic and nerve-wracking event known as EDL -- Entry, Descent and Landing.

A patch of Martian soil analyzed by NASA's rover Spirit is so rich in silica that it may provide some of the strongest evidence yet that ancient Mars was much wetter than it is now.
