Tibetan Microbe Mats

Searching for clues to the potential for life on Mars, NASA scientists recently explored microbial communities in some of the world's oldest, driest and most remote deserts in China's northwest region, and found evidence suggesting that conditions there may be similar to those in certain regions of Mars.

NASA photographs recently revealed bright new deposits seen in two martian gullies, like this one in a crater in the Centauri Montes Region. The images suggest that water carried sediment through them sometime during the past seven years.
