NASA Adds To Mars Global Surveyor Photo Album
The picture from a crater at 39.0°S, 166.1°W, is one of the highest-resolution images obtained from Mars. Its resolution is 1.5 meters (5 feet) per pixel--objects the size of school buses can be resolved in the full size image. The gullies in these craters originate at a specific layer and may have formed by release of groundwater to the martian surface in geologically recent times.
