Thursday’s Classroom: Divining Water on Mars (Part 3 of 3) NASA Science

In June 2000 NASA scientists revealed new pictures of the planet Mars that seem to show gullies carved by flooding water. Some of the gullies may have formed thousands of years ago, but others appeared to be just a few days or weeks old. Scientists at the press conference expressed amazement at the possibility of liquid water on present-day Mars. Mars is extraordinarily cold and dry, and keeping water in its liquid form near the surface of the Red Planet is nearly impossible.
