Sampling An Asteroid

Asteroid expert Professor Simon Green joins the Space Boffins to discuss missions to collect samples from space rocks and return them to Earth, and the perils of re-directing asteroids heading our way. Richard and Sue also chat to Romanian astronaut Dumitru-Dorin Prunariu about life on the first international space station, Salyut 6, and Europe’s ambitious Mercury mission gets packed-up ready for launch.
