From Nick Canning, Coleraine, County Londonderry, UK
I fear Mars would be a dreadful destination for colonising for all the reasons stated, plus the planet-wide dust storms that would kill any hope of photosynthesis for periods and interrupt solar power. And what about surviving the maddening isolation? At least on the ISS one can look out of the window at the beauty of Earth below and imagine all the other life with which we share the planet. Mars isn’t just hostile, but lethal, a place for which we have no evolutionary adaptation.
