Ice lake in crater on Mars surface

by maverickis on July 31, 2005

The European Space Agency’s (ESA) Mars Express has taken an image of a modest ice lake on the Red Planet.

The frozen patch of water ice is in an unnamed impact crater. The feature is located on Vastitas Borealis, a broad plain that covers much of the far northern latitudes.

The crater is 22 miles (35 kilometers) wide and has a maximum depth of roughly 1.2 miles (2 kilometers) beneath the crater rim.

The ice patch seems to be present all year round, as the temperature and pressure are not high enough to allow the frozen water to escape into the atmosphere.
