Could life on Earth be wiped out by a killer asteroid? The short answer is yes. This month the Space Boffins hear about a new European telescope to spot the threat before it's too late. Richard Hollingham and Sue Nelson are joined at the Royal Astronomical Society in London by Robert Massey and Helen Klus to discuss how astronomy could save the world. Richard also chats to NASA astronaut Steve Bowen who reveals what it will be like to live in the 'cramped' new Orion spacecraft and the perils of returning to Earth after a mission to the Moon or Mars.
