More Evidence of Water on Mars
Posted on February 21, 2007Images from the Mars Reconnaissance Orbiter reveal more evidence of water on Mars. The ridges shown in the photo are evidence of erosion from water and give scientists valuable clues about Mars' past.
This month the Mars Reconnaissance Orbiter spacecraft will break the record for the most science data returned by any Mars spacecraft. Although NASA scientists are thrilled with the amount of data coming in, the engineers are still trying to figure out why two of instruments are not performing as they are supposed to. Let's hope they get that fixed somehow.Ridges as Evidence of Fluid Alteration
Tectonic fractures within the Candor Chasma region of Valles Marineris, Mars, retain ridge-like shapes as the surrounding bedrock erodes away. This points to past episodes of fluid alteration along the fractures and reveals clues into past fluid flow and geochemical conditions below the surface.
