NASA Mars Picture of the Day: Ripples and Dunes
Mars Global Surveyor Mars Orbiter Camera
MGS MOC Release No. MOC2-1475, 27 May 2006
 NASA/JPL/Malin Space Science Systems |
| This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dark sand dunes on the floor of an impact crater west of Hellas Planitia. Portions of the crater floor are exposed near the center and lower right corner of the image but, in general, the floor is covered by large, windblown ripples. The dark dune sand typically covers ripples, indicating that the dunes are younger and made of a more mobile material. |
