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.
Today scientists working on the Mars Curiosity Rover mission made an important announcement: The rover used its lasers to "sniff" for methane. As NASA explains, methane is a "precursor chemical" for life, because creatures like us produce methane.
The Rover came up empty, or rather the most sensitive measurements ever taken in the planet's atmosphere reveal "little to no methane."
