Earlier this year, Professor Stephen Hawking warned the human race that, unless we found a way to colonise another planet in the next hundred years, we would face a very real threat of extinction. He said: \u201cWith climate change, overdue asteroid strikes, epidemics and population growth, our own planet is increasingly precarious.\u201d<\/p>\n
The idea of a brave band of people leaving Earth to start a new life elsewhere in the galaxy isn\u2019t new. Rocket pioneer Robert H Goddard described an \u201cinterstellar ark\u201d in 1918, and ten years later his Russian counterpart Konstantin Tsiolkovsky, known as the father of astronautic theory, wrote about a Noah\u2019s Ark that would fly in space for thousands of years.<\/p>\n
