Images taken of the same areas over time showed investigators that liquid water likely flowed through gullies in Martian craters during the past seven years. Telltale deposits of debris suggest that sediments were washed downhill by occasional liquid flows.  “The shapes of these deposits are what you would expect to see if the material were carried by flowing water,” said Michael Malin, president and chief scientist at Malin Space Science Systems.
