Big News From Mars? Rover Scientists Mum For Now
November 20th, 2012Via: NPR:
Scientists working on NASA’s six-wheeled rover on Mars have a problem. But it’s a good problem.
They have some exciting new results from one of the rover’s instruments. On the one hand, they’d like to tell everybody what they found, but on the other, they have to wait because they want to make sure their results are not just some fluke or error in their instrument.
It’s a bind scientists frequently find themselves in, because by their nature, scientists like to share their results. At the same time, they’re cautious because no one likes to make a big announcement and then have to say “never mind.”
The exciting results are coming from an instrument in the rover called SAM. “We’re getting data from SAM as we sit here and speak, and the data looks really interesting,” John Grotzinger, the principal investigator for the rover mission, says during my visit last week to his office at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. That’s where data from SAM first arrive on Earth. “The science team is busily chewing away on it as it comes down,” says Grotzinger.
SAM is a kind of miniature chemistry lab. Put a sample of Martian soil or rock or even air inside SAM, and it will tell you what the sample is made of.
Grotzinger says they recently put a soil sample in SAM, and the analysis shows something earthshaking. “This data is gonna be one for the history books. It’s looking really good,” he says.
Grotzinger can see the pained look on my face as I wait, hoping he’ll tell me what the heck he’s found, but he’s not providing any more information.
While I was out walking, I got the impression that I would meet someone named Sam today.
