Mysterious Mars Methane: Curiosity Sees No Sign

story imageIn the past decade, probes orbiting Mars and telescopes on Earth have detected what appeared to be plumes of methane gas from the Red Planet. The presence of colorless, odorless, flammable methane on Mars, the simplest organic molecule, helped revive the possibility of life once existing, or even currently living, just below the planet's surface. Scientists have suspected that methane stays stable in the Martian atmosphere for only about 300 years, so whatever is generating this gas did so recently.

A large-scale non-biological source of methane production on Mars might have been an even more exciting result. A renewable process humans might be able to adapt for use on Earth to meet our energy needs. But Curiosity has revealed no trace of methane on the Martian surface.

"Based on earlier observations, we were expecting to land on Mars and measure background levels of methane of at least several parts per billion, but saw nothing," Webster told Space.com.

"It's a mystery surrounded by an enigma here," said imaging physicist Jan-Peter Muller.

It would be really exciting to find some form of life there, but maybe they just aren't in the right spot.

As far as harvesting methane...We currently keep much livestock, and I hear rant about how cows are killing the ozone. Can't we collect that bovine flatulence somehow? It might be easier and less expensive than getting it from a neighboring planet, and it doesn't seem like most in our society will be excluding beef from our diet anytime soon. Why not get the most out of the cows as possible? I guess PETA would would be like, "THAT'S THEIR GAS, YOU GIVE IT BACK TO THE COWS!!!"
