methane not released by wind on mars experts find
Wind erosion has been ruled out as the primary cause of methane gas release on Mars, Newcastle University academics have shown. Methane can be produced over time through both geological and biological routes and since its first detection in the Martian atmosphere in 2003, there has been intense speculation about the source of the gas and the possibility that it could signal life on the planet.Previous studies have suggested the methane may not be evenly distributed in the atmosphere around Mars,...
