“This data is gonna be one for the history books. It’s looking really good,” Grotzinger told NPR in an segment published Nov. 20. Curiosity’s SAM instrument contains a vast array of tools that can vaporize soil and rocks to analyze them and measure the abundances of certain light elements such as carbon, oxygen, and nitrogen – chemicals typically associated with life.
The mystery will be revealed shortly, though. Grotzinger told Wired through e-mail that NASA would hold a press conference about the results during the 2012 American Geophysical Union meeting in San Francisco from Dec. 3 to 7. Because it’s so potentially earth-shaking, Grotzinger said the team remains cautious and is checking and double-checking their results. But while NASA is refusing to discuss the findings with anyone outside the team, especially reporters, other scientists are free to speculate.
