WASHINGTON, Dec. 3 (Xinhua) -- Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the soil, U.S. space agency NASA said Monday.
Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiosity's arm delivered to an analytical laboratory inside the rover, NASA said in a statement.
Curiosity is the first Mars rover able to scoop soil into analytical instruments. The specific soil sample came from a drift of windblown dust and sand called "Rocknest". The site lies in a relatively flat part of Gale Crater still miles away from the rover's main destination on the slope of a mountain called Mount Sharp. The rover's laboratory includes the Sample Analysis at Mars (SAM) suite and the Chemistry and Mineralogy (CheMin) instrument. SAM used three methods to analyze gases given off from the dusty sand when it was heated in a tiny oven. One class of substances SAM checks for is organic compounds -- carbon-containing chemicals that can be ingredients for life.
