NASA has photographic evidence that mud might have flowed very recently on Mars. And when I say very recently, I’m not talking about a geological timescale. It might have happened just a few years ago. If this is true, it is almost certainly also true that there is mud on Mars today.
NASA scientists compared pictures of the Centauri Montes region of Mars taken by NASA’s Mars Global Surveyor in September, 2005 to a picture taken of the same region in August, 1999. The 2005 picture showed a distinct difference from the 1999 picture that could be explained by a mud flow.
The existence of mud would add a new complication to a possible manned mission to Mars. If the mud’s existence proves to be true, scientists will have to develop a doormat that astronauts can use to wipe their feet before reentering their space capsule after taking a walk on the Martian surface. Their mothers would insist on it.
