Curiosity Rover's Secret Historic Breakthrough?

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. A report from the Rover's principal investigator, geologist John Grotzinger of Caltech, says that Curiosity has uncovered exciting new results from a sample of Martian soil recently scooped up.

The mystery will be revealed shortly, though. NASA will hold a press conference about the results during the 2012 American Geophysical Union meeting in San Francisco from December 3 to 7. Because it's so potentially earth-shaking, the Rover team remains cautious and is checking and double-checking their results.
