The winds of Mars leave their marks on many of the 11,664 new pictures being posted on the Internet today by the camera team for NASA’s Mars Global Surveyor mission. In one image, the pattern of sand dunes on a patch of southern-hemisphere desert resembles scales on a fish. On a larger scale, full-globe Mars images show wispy water ice clouds shaped by winds as the seasons change. Other new images reveal details of features such as gullies, landslides and seasonal frost.
