If there is anyone who should be able to shed some deeper light of the prospects of living in space, it is the man who is arguably the UK's greatest living science fiction author – Stephen Baxter. Having written dozens of highly successful Sci-Fi books and co-authored with the likes of Arthur C Clark and Terry Pratchett, Stephen gives us his expert views on the problems – and the benefits – of living in space, and the "colony ships" that could expand the horizon of the human race, take us to nearby star systems, and explore where no one has gone before.
