that will make me go
SAM is the rover's onboard chemistry lab, and it's capable of identifying organic compounds — the carbon-containing building blocks of life as we know it.
NASA's Mars rover Curiosity has apparently made a discovery "for the history books
So why doesn't Grotzinger want to share his exciting news? The main reason is caution. Grotzinger and his team were almost stung once before. When SAM analyzed an air sample, it looked like there was methane in it, and at least here on Earth, some methane comes from living organisms. But Grotzinger says they held up announcing the finding because they wanted to be sure they were measuring Martian air, and not air brought along from the rover's launchpad at Cape Canaveral. "We knew from the very beginning that we had this risk of having brought air from Florida. And we needed to diminish it and then make the measurement again," he says. And when they made the measurement again, the signs of methane disappeared.
