At http://phys.org/print296907712.html … we've had Mars chocolate bars and claims it is made of cheese, canals on Mars and little green men, and 'Journey into Space' (not forgetting Dr Quatermass) and even Mars running riot in the solar system – but now we have accumulating evidence that life might have began on Mars.
Meanwhile, Titan is causing problems – go to www.sciencenews.org/view/generic/id/352823/description/Titan-becomes-eve… … it seems Titan may have a thick and rigid crust of ice – which means some assumptions are past their sell by date. Cassini has peered through Titan's orange haze to discover methane and other hydrocarbons. Titan's atmosphere contains so much methane that if it was all rounded up it would form a layer ten metres thick. Where odes the methane come from, that is the question now being asked. It was supposed to come from beneath the surface of Titan but this cannot possibly be the case if the thick ice crust is taken into account. Perhaps the next step is to find out what the ice crust is made from?
