Sand Flow On Mars:
Previously scientists reported that the sign of flow may be the presence of water in the past, but it is confirmed that the flow is just sand. The sand flows from top of the hill towards down. New Image from Mars Reconnaissance Orbiter reveals the flow of sand. The finding is published in the Journal of Nature Geo-Science Argue against the presence of enough liquid water for microbial life to thrive at these sites. Reporters propose the possibilities like the presence of small amount of water, indicated by the detection of hydrated salts at some of the flows.
