CAPE CANAVERAL, Fla. – David Blake, NASA principal investigator for the Chemistry and Mineralogy (CheMin) investigation by the Curiosity rover, explains the experiment to the media in NASA Kennedy Space Center's Press Site auditorium in Florida during prelaunch activities for the agency’s Mars Science Laboratory (MSL) launch. CheMin is designed to analyze powdered rock and soil samples by identifying and quantifying their mineral content using X-ray diffraction, a first for a mission to Mars. The car-sized Martian rover, Curiosity, has 10 science instruments designed to search for signs of life, including methane, and help determine if the gas is from a biological or geological source. Liftoff of MSL aboard a United Launch Alliance Atlas V rocket from Space Launch Complex-41 on Cape Canaveral Air Force Station is planned during a launch window which extends from 10:02 a.m. to 11:45 a.m. EST on Nov. 26.
