Scientists working on NASA's six-wheeled rover on Mars have a problem. But it's a good problem. They have some exciting new results from one of the rover's instruments. On the one hand, they'd like to tell everybody what they found, but on the other, they have to wait because they want to make sure their results are not just some fluke or error in their instrument. 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," John Grotzinger, the principal investigator for the rover mission, [said]. SAM is a kind of miniature chemistry lab. Put a sample of Martian soil or rock or even air inside SAM, and it will tell you what the sample is made of. Grotzinger says they recently put a soil sample in SAM, and the analysis shows something earthshaking. "This data is gonna be one for the history books. It's looking really good," he says. Grotzinger says it will take several weeks before he and his team are ready to talk about their latest finding.
