Happy St. Valentine's Day from the Red Planet! The Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) captured this unique view of a bright, heart-shaped mesa in the south polar region on November 26, 1999. This feature is located in the Promethei Rupes region near 79.6°S, 298.3°W. Sunlight illuminates the scene from the lower left. The heart is about 255 meters (279 yards) across. The presence of this mesa indicates that the darker, rough terrain that surrounds it was once covered by a layer of the bright material.
Earlier in 1999, MGS MOC saw another valentine heart, but instead of a mesa, the feature was expressed as a pit. You can view that image by CLICKING HERE.
