Keith’s note: According to “Slope Streaks on Mars – Not A Sign Of Water After All?” from Brown University: “A new study led by the University of Bern and Brown University in the U.S. casts doubt on one of the most tantalizing clues that water might be flowing on present-day Mars. Researchers analyzed a global database of 500,000 enigmatic streaks that occur on steep Martian slopes, concluding that they’re most likely caused by dry processes rather than liquid flow.” This could have important impacts on Mars exploration – by droids as well as humans. Remember that whole ‘water may be flowing on the surface of Mars’ thing back in 2000? (NASAWatch broke the story). People went totally crazy. Now there’s a suggestion that things are possibly different than we thought. Will NASA’s Astrobiology program mention it? Most likely not.
