Brian Cox and Robin Ince journey through the asteroid belt to discuss space rocks with Dr Who companion John Bishop, professor of planetary science Sara Russell and astrophysicist Alan Fitzsimmons. They learn that these seemingly innocuous rubble like rocks can hold secrets to the formation of the solar system but just don’t jump on one – you may shoot straight through it! They find out about the latest space missions that are trying to bump into or grab bits of asteroids and how these technological feats are helping to avoid the end of life on earth as we know it.
