Martian Rocks May Contain Methane
Monday, June 6th, 2005/. “When methane was found in the Martian atmosphere last year, some scientists thought this was indirect evidence of methane-producing bacteria. But minerals such as olivine can create methane in a process known as serpentinization. Geologists calculated that a global, 50-centimetre-thick layer of olivine could account for the methane. One geologist said, ‘I’d love to see bugs, but you can’t just go on hope. You have to consider the geological options.’ Other scientists are unsure whether methane on Mars even exists.”
