Three wide angle views taken by the Mars Orbiter Camera on NASA's Mars Global Surveyor at intervals approximately one Mars year apart show similar spiral dust clouds over a volcano named Arsia Mons. The upper-left image was taken on June 19, 2001, the first day of southern winter on Mars. The upper-right image was taken on April 24, 2003, in late southern autumn on Mars. The lower image was taken on Feb. 25, 2005, slightly earlier in late southern autumn on Mars.

When a boulder rolls down a dusty slope, it can leave behind a trail of depressions. Usually known as boulder tracks, these features have been documented and studied on Earth, the Moon, and Mars. Geologists studying the Moon and Mars can use these tracks to learn about the physical properties of the fine-grained debris encountered by the boulder as it rolled down the slope.

| This pair of images shows a dune as it appeared on July 17, 2002, (left) and as it appeared on April 27, 2005, (right). During this period, a couple of gullies formed on the dune slip face. It is critical to recognize that the 2002 image was obtained at a time of year when the incident sunlight was coming in from a lower angle, relative to the horizon, than in the 2005 image. If the gullies had been present in 2002, their appearance would be sharper and more pronounced than they are in the 2005 image. The gullies simply did not exist on July 17, 2002.

The discovery of bright deposits on Mars, announced on 7 December 2006 by NASA, could indicate that liquid water has recently flowed on a few locations on the planet.
The newly discovered deposits were identified by comparing different images of the same area taken by NASA´ Mars Global Surveyor (MOC camera), over a period of few years. The images suggest that water may have flowed there sometime within the past seven years.
