Polar Views of Mars: Pictures by the Red Rover Goes To Mars International Student Scientist Team

October 21, 2009
(C) Nilosyrtis Mensae Valleys and Boulders in the Fretted Terrain.

Red Rover Science Team Caption: "This image was taken in the fretted terrain area located in the middle latitudes of Mars. Interesting features in this area are dunes, valleys, and mysterious black boulders that are as big as 15 to 25 meters (49 to 82 feet). The puzzling position of these mysterious rocks and the lack of our ability to understand how they got there reminds us how much there is still left to discover about our mystery planet."
