Before the specific mention of methane as a 'possibility' there was a comment about having found substance(s) that would evaporate at temperatures just 20-30 degrees warmer than ambient ground temperatures of -220C or -230C, possibly sublimed off a wider area around the crater by falling warm debris. Methane has a boiling point in this range - but are there other candidates?

Makes me wonder whether we could get brief, regular bursts of cometary style activity by putting a huge reflective surface in lunar polar orbit. It would make boring old Luna look a bit like Enceladus! (entirely different mechanism, of course) |
