The exciting results are coming from an instrument in the rover called SAM. "We're getting data from SAM as we sit here and speak, and the data looks really interesting," says John Grotzinger. He's the principal investigator for the rover mission. SAM (Sample Analysis at Mars) is a suite of instruments onboard NASA's Mars Science Laboratory rover, Curiosity.
Grotzinger says they recently put a soil sample in SAM, and the analysis shows something Earth-shaking. "This data is gonna be one for the history books. It's looking really good," he says."
