Not one but four astronauts feature in this month's Space Boffins. Sue Nelson and Richard Hollingham chat to astronaut Nicole Stott about her book Back to Earth; we hear about the drama of launch, what to do when things go wrong and the challenges of interviewing other astronauts. Sue also attends a glamorous space event in London to catch up with two Apollo legends, British ESA astronaut Tim Peake, and Space Shuttle pilot Susan Kilrain. Like this podcast?
