Curiosity Rover’s Secret Historic Breakthrough? Speculation Centers On Organic Molecules
Much of the internet is buzzing over upcoming “big news” from NASA’s Curiosity rover, but the space agency’s scientists are keeping quiet about the details.
The report comes by way of the rover’s principal investigator, geologist John Grotzinger of Caltech, who said that Curiosity has uncovered exciting new results from a sample of Martian soil recently scooped up and placed in the Sample Analysis at Mars (SAM) instrument.
“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.
“If it’s going in the history books, organic material is what I expect,” says planetary scientist Peter Smith from the University of Arizona’s Lunar and Planetary Laboratory. Smith is formerly the principal investigator on a previous Mars mission, the Phoenix lander, which touched down at the Martian North Pole in 2008. “It may be just a hint, but even a hint would be exciting.”
