NASA Confirms Evidence That Liquid Water Flows on Today’s
Mars
*These
dark, narrow, 100 meter-long streaks called recurring slope lineae flowing
downhill on Mars are inferred to have been formed by contemporary flowing
water. Recently, planetary scientists detected hydrated salts on these slopes
at Hale crater, corroborating their original hypothesis that the streaks are
indeed formed by liquid water. The blue color seen upslope of the dark streaks
are 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 site produced by
High Resolution Imaging Science Experiment (University of Arizona). Vertical
exaggeration is 1.5. Sept.
