Gale crater

Caption

These images show Gale crater in High Resolution Stereo Camera (HRSC) images, with elevation colorised in blue. The image on the left shows the standard model where Gale crater is generally assumed to have been a large lake (flooded to at least an elevation of ~4,000m). The image at the right is the model proposed by Liu et al., in which only very small, shallow lakes existed on the floor of Gale crater (with the crater flooded only to an elevation of approximately ~4,500m). Most the sediments were deposited from the atmosphere as air-fall deposits and later weathered from precipitation or ice-melt. A star marks the rover’s landing site.
