It's been reported today that a release of methane on Mars, three times larger than ever detected before, was discovered on Wednesday. On Friday the Curiosity rover had its plans altered, in order to concentrate on this phenomenon, it's said. Preliminary results of this investigation are expected on Monday. Further information is available in the article, linked below:

Regarding the brainstorming about the origin of the CH4, I've two almost entirely different lines of thoughts or questions:
1. Have exogenic causes been ruled out? I'm thinking of CH4 bearing cometary remnants. Impacts would be seasonal, when Mars would cross the orbit of the debris. They may cause local peaks of trapped gasses. and 2. May the local clay be able to trap CH4 of an ancient CH4 atmosphere, and release traces of it during summer? Methane is a well-known strong greenhouse gas, and assuming an ancient CH4 atmosphere reminiscent of Titan may help to resolve the faint young Sun paradox for Mars. |
