NASA Mars Picture of the Day: Tyrrhena Dunes
Mars Global Surveyor Mars Orbiter Camera
MGS MOC Release No. MOC2-1426, 8 April 2006
 NASA/JPL/Malin Space Science Systems |
| This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a portion of a field of dark sand dunes superposed on the light-toned floor of a crater in eastern Tyrrhena Terra. The orientation of the dunes—with the steep faces toward the south (bottom)—suggests that winds generally blew from north to south at the time the dunes were formed. |
