New details have emerged about the history of water on Mars, gleaned from the 2008 NASA Phoenix Mars Mission. Scientists found patterns in the ground near the lander, multi-sided shapes about three to ten meters in size. The shapes are created when the surface contracts and the ice cracks. Sand fills in the cracks before the ice expands and buckles the surface to make the distinctive patterns.
