Slope streaks once believed to be signs of water on Mars might really be signs of rockfall and high winds, a new study says.

Satellite images of the Red Planet suggest scientists were wrong about these strange Martian features.

Researchers analyzed a global database of 500,000 strange streaks that occur on steep Martian slopes, concluding that they're most likely caused by dry processes rather than liquid flow.

The results will be worth the effort and the cost, not just in understanding the world around us in general but also in determining if there has ever been life on Mars. Dr. Bruce Jakosky has been ...
