Methane pulses on Mars possibly driven by atmospheric pressure changes

Posted by in category: alien life

New research shows that atmospheric pressure fluctuations that pull gases up from underground could be responsible for releasing subsurface methane into Mars’s atmosphere; knowing when and where to look for methane can help the Curiosity rover search for signs of life.

“Understanding Mars’s variations has been highlighted by NASA’s Curiosity team as the next key step towards figuring out where it comes from,” said John Ortiz, a graduate student at Los Alamos National Laboratory who led the research team. “There are several challenges associated with meeting that goal, and a big one is knowing what time of a given sol (Martian day) is best for Curiosity to perform an atmospheric sampling experiment.”

The paper was published Jan. 22 in the Journal of Geophysical Research: Planets.
