Curiosity findings show 2 percent of Mars soil contains water

•, by Nick Statt
 After examining fine-grained soil particles extracted by the Curiosity rover from beneath the surface of Mars, scientists have concluded that roughly 2 percent of the Martian surface soil is made up of water. While showing no indication of organic material besides Earth-transported microbes, the results bode well for future manned missions to Mars, wherein astronauts could mine the soil for water, and advance scientists' understanding of Mars' history.

The findings, published Thursday in the journal Science, are part of one article in a five-paper special section on the Curiosity mission that began in August 2012. "One of the most exciting results from this very first solid sample ingested by Curiosity is the high percentage of water in the soil," lead author Laurie Leshin, dean of the School Science at Rensselaer Polytechnic Institute, said in a NASA press release.
