Mars Needs Bathing Suits

“If it moves like water, it may very well be water.”
Oregon State planetary science professor Joe Levy discusses the “recurring slope linneae” visible on the surface of Mars in recent high-resolution photographs. Some people think the lines, which run downhill into ravines, offer proof that water exists in frozen form on the red planet’s crust, and melts into flowing liquid during warmer months. Of course, with James Cameron fresh back from his trip seven miles deep into the Mariana Trench, other possibilities come to mind.
