Ancient Martian Atmosphere May Be Sequestered In Clay

New research suggests that Mars' missing atmosphere may have been absorbed by minerals in the planet's clays, in a process similar to geological reactions on Earth. It may explain Mars' loss of its atmosphere and potential to support life, with methane possibly still present and usable as an energy source. Longtime Slashdot reader Baron_Yam writes: Conditions on early Mars were highly likely to have had CO2 carried down into the ground by water, where reactions with rock resulted in iron oxide (and Mars' rust-red surface) and released hydrogen, which in turn reacted with the water to form methane that was bound in smectite clays.
