Will NASA soon announce discovery of Martian fossils by Curiosity Rover?

NASA is about to make a big announcement from its Curiosity Rover Mars mission according to John Grotzinger, its principal investigator. Will it be a giant leap forward in the search for life on Mars? Speculation began soon after Grotzinger gave an interview on NPR public radio on November 20 where he said: "This data is gonna be one for the history books. It's looking really good." In the NPR interview, Grotzinger said it would be several weeks before his team would announce their finding. A clue as to what was discovered is that the data comes from Curiosity's Sample Analysis at Mars instrument – basically an onboard chemistry lab that is capable of identifying organic compounds – the carbon-containing building blocks of life as we know it. While organic compounds do not necessarily mean that life exists/existed on Mars, they are a vital ingredient in the formation of life. NASA’s big upcoming announcement is most likely to be that it has discovered organic compounds on Mars – possibly, the fossilized remains of ancient Martian microbes.
