This video uses three-dimensional modelling of a gullied crater in the Centauri Montes region of Mars and simulates a flight over that landscape. One gully inside the crater has a deposit of light-toned material that was not present in 1999 but appeared by 2004, as determined from before-and-after images taken by the Mars Orbiter Camera on NASA's Mars Global Surveyor. The deposit is several hundred meters or yards long.



The imagery and stereo information for this video come from images taken on Dec. 12, 2006, by the High Resolution Imaging Science Experiment (HiRISE) camera and the Context Camera (CTX) on NASA's Mars Reconnaissance Orbiter.
