few weeks after its first anniversary on the red planet, the NASA's rover Curiosity is still working. The first scoop of soil analysed by the analytic suite in the belly of martian rover reveals that fine materials on the surface of the planet contain several percent water by weight. The scientists used the ChemCam, CheMin instruments, the Alpha Particle X-ray Spectrometer (APXS) and the Sample Analysis at Mars (SAM) suite aboard NASA’s Curiosity Rover to perform the analysis.
About 2 percent of the soil on the surface of Mars is made up of water, which is great resource, and interesting scientifically. The sample also released significant carbon dioxide,oxygen and sulfur compounds when heated.
The result were published in Science as one article in a five-paper special section on the curiosity mission.
