Dr Adam Rutherford and Dr Hannah Fry investigate everyday mysteries. Could we live on another planet? The doctors consider the challenges of living in space.
Listener Paul Don asks: "I'm wondering what's the feasibility of terraforming another planet i.e. Mars and if it's possible to do the same thing with something like the moon? Or, why isn't there already a moon-base? Surely that's easier."
Adam & Hannah consider moving to another planet, and discover what challenges they would need to overcome to live in space.
They consult engineer Prof Danielle George from the University of Manchester and Dr Louisa Preston, UK Space Agency Aurora Research Fellow in Astrobiology.
Adam also hears about attempts to recreate a Martian base on a volcano in Hawaii. He calls HI-SEAS crew member Tristan Bassingthwaighte, who has just emerged from a year of isolation.
