Mars Curiosity Finds Mud Cracks, Showing Signs of Wet Past

By Editor 19 January 2017

On Tuesday, NASA's Curiosity rover released images that resemble dried mud that we see here on Earth after long rains, prompting an investigation to finding more hints of water on Mars. NASA describes the scene found at the lower region of Mount Sharp, as "slabs of rock cross-hatched with shallow ridges that likely originated as cracks in drying mud." NASA says that the rock slab being called "Old Soaker." dates back 3 billion years and could be " the first mud cracks," technically called "desiccation cracks." Previous Mars missions have shown evidence about the Red Planet being a much wetter place and being home to large lakes in the past.
