Photo: Liquid Water Recently Seen on Mars?

[loki]

Liquid droplets seem to form and move on the leg of the Phoenix Mars lander, as seen in images taken on days 8, 31, and 44 (seen above from left to right) of the craft's mission.

Scientists think the water could stay liquid even in the frigid Martian arctic because of its high concentration of perchlorates, salts that acts like antifreeze.
