(contracted; show full)and JPL held a press conference to announce that evidence found by the rover ''Opportunity'' shows that the bedrock investigated by her formed most likely under flowing saltwater. Mission scientists described two reasons for this conclusion: "Crossbedding" features in the layered rock "Last Chance" seen on a mosaic generated from MI pictures, and the chemistry of the rock as it relates to the elements chlorine and bromine.

Dr. John Grotzinger, science member from [[
Massachusetts Institute of Technology|MIT]] said that bedding patterns in some finely layered rocks indicate the sand-sized grains of sediment that eventually bonded together were shaped into ripples by water at least 50 mm (2 inch) deep, possibly much deeper, and flowing at a speed of 100 to 500 mm/s (4 to 20 in/s).
