    Drywashing Mars

    NASA's Curiosity has found an ancient stream bed on Mars! Better hurry to beat the crowds!

    NASA - NASA Rover Finds Old Streambed on Martian Surface

    PASADENA, Calif. -- NASA's Curiosity rover mission has found evidence a stream once ran vigorously across the area on Mars where the rover is driving. There is earlier evidence for the presence of water on Mars, but this evidence -- images of rocks containing ancient streambed gravels -- is the first of its kind.

    Scientists are studying the images of stones cemented into a layer of conglomerate rock. The sizes and shapes of stones offer clues to the speed and distance of a long-ago stream's flow.

    "From the size of gravels it carried, we can interpret the water was moving about 3 feet per second, with a depth somewhere between ankle and hip deep," said Curiosity science co-investigator William Dietrich of the University of California, Berkeley. "Plenty of papers have been written about channels on Mars with many different hypotheses about the flows in them. This is the first time we're actually seeing water-transported gravel on Mars. This is a transition from speculation about the size of streambed material to direct observation of it."

    Thanks for the post, interesting stuff.

    I have always thought that life on mars billions of years ago was much like earth is today.

    Well lets see.
    How far to bedrock on Mars, from Earth?
    Roughly 65 million miles if Earth and Mars are in near orbit position.
