Curiosity Rover Confirms Ancient Lake(s) in Gale Crater on Mars

Sedimentary strata at the base of Mount Sharp as seen at the Kimberly location. The strata in the foreground dip toward Mount Sharp, providing evidence of the former lake-filled depression that used to exist before most of the mountain formed. Image Credit: NASA/JPL-Caltech/MSSS

Last week there was the exciting news that Mars still […]

The Saline Slopes of Mars: NASA Confirms Evidence for Flowing Liquid Water

False-color image of RSL on slopes in Hale crater. The blue color is thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same […]
