The European Space Agency's Mars Express orbiter has found huge deposits of ice on the south pole of Mars. Scientists have calculated that if melted, water would cover the whole planet up to 36 feet of water. The deposits are up to 2.3 miles thick, about as large as Texas and lie under a layer of solid carbon dioxide mixed with more water and dust. The goal of scientists now is to determine if life thrived before or still does in the ice.
