Submission + - More Martian Water Evidence

tubapro12 writes: NASA's Mars Reconnaissance Orbiter has detected light-toned bedrock on Mars occurring in an alternating pattern with darker bedrock within a rift valley. Researchers at the University of Arizona point to this as a product of a liquid, probably water, passing through the rocks.

"On Earth, bleaching of rock surrounding a fracture is a clear indication of chemical interactions between fluids circulating within the fracture and the host rock," Okubo and co-author Alfred S. McEwen reported in the paper. The researchers also said that layered outcrops can indicate cycles with materials deposited by regular episodes of water, wind or volcanic activity.

When all else fails, read the instructions.
