Season 59 Episode
Royal Institution Christmas Lectures - Season 50 Episode 2 Life in Orbit
5.10 60 minutes In the second lecture, Kevin explores life in orbit on board the International Space Station. As Tim settles in to his new home he sends special reports about what it takes to live and work in space.
Four hundred kilometres above the Earth, hurtling at a speed of 17,500mph, astronauts' bones and muscles waste away, the oxygen they breathe is artificially made, and they face constant threats from micrometeorites, radiation and extreme temperatures. If a medical emergency strikes, Tim is a very long way from home.
In its 15-year lifetime, the International Space Station has never had a major accident. With a British astronaut in orbit, gravity-defying experiments and guest astronauts in the lecture theatre, Dr Fong shows us how to survive life in orbit.
