What would it really be like to live on other planets, and what are the implications of humans colonising space?

Living in space is becoming a real prospect, as plans develop for mass space travel and discoveries are made of environments that can support life on other worlds.

Presenters Timandra Harkness and Leo Johnson travel to NASA's main space habitation research facility in Virginia, USA, to find out how humans might actually colonise deep space. They also learn about the search for alien intelligence, how private industry plans to harvest the resources of other planets, and why settling in space could offer us all a very different model of society in future.
