Have you ever had to keep a secret that you really, really wanted to share, but you couldn't because the timing wasn't right? That seems like the position NASA is in right now. After a whirlwind first couple of months on the surface of the Red Planet, the rover Curiosity has been silent, idling for sometime. Analysts Earth-side are poring over data from a series of five sand samples recently analyzed in the rover's mobile chemistry lab, the Sample Analysis at Mars (SAM) unit. There's no word on what they've found quite yet, but researchers are willing to say that it's something big. Like, historical event big.
Considering Curiosity's mission is to find life on Mars, there's pretty much just one thing that could be considered historically big news from the rover -- signs of life on Mars. Not that anyone is saying that right now
-- but sometimes, the way in which you don't say something could speak more than what you do say, and this certainly feels like one of those times.
