Space Boffins Richard Hollingham and Sue Nelson's star (and space) studded podcast includes the first woman in space, cosmonaut Valentina Tereshkova, and astronaut Tim Peake. Britain's first European Space Agency astronaut discusses the final training before his December launch and why it's important to learn how to fix a toilet. Former space shuttle engineer and Spaceflight editor David Baker is in the studio to discuss the Soyuz rocket that will take Tim to the Space Station, as is Yen Yau from Into Space - a new UK Space Agency backed film project for young space fans. Naturally, they all discuss the Martian.
