Evidence of water ice on mars.

It’s official: the Phoenix Lander has discovered ice on Mars.
A few days ago, the lander exposed some bright white chunks of material
while retrieving a soil sample. These spots have since disappeared over
the following days, suggesting they’ve melted. An additional trench
found a hard layer at the same depth as the original ice.

The spacecraft team has been dealing with some data storage issues as well and will be pushing a software patch soon.
