Rover Finds Ancient Streambed On Martian Surface

sighted writes "NASA reports that its Curiosity rover mission has found evidence that a stream once ran vigorously — and for a sustained amount of time — across the area on Mars where the rover is driving. There is, of course, earlier evidence for the presence of water on Mars, but NASA says this evidence, images of rocks containing ancient streambed gravels, is the first of its kind."

Both mercury and bromine could be liquid at reasonable temperatures. Both are also just as unlikely to be in amounts to have streams.
