This picture released on May 26, 2008 by NASA shows a polygonal pattern in the ground near NASAs Phoenix Mars Lander, similar in appearance to icy ground in the arctic regions of Earth. Phoenix touched down on the Red Planet at 4:53 p.m. Pacific Time (7:53 p.m. Eastern Time) on May 25, 2008, in an arctic region called Vastitas Borealis, at 68 degrees north latitude, 234 degrees east longitude. This is an approximate-color image taken shortly after landing by the spacecrafts Surface Stereo Imager, inferred from two color filters, a violet, 450-nanometer filter and an infrared, 750-nanometer filter.
