Robin Ince and Brian Cox are joined by comedian Helen Keen ("It is Rocket Science") and space medicine expert Dr Kevin Fong, to discuss the future of human space travel. As NASA's space shuttle program comes to a close, what does the future hold in terms of humans bid to leave the confines of earth, and what has human space travel provided in terms of scientific understanding back at home? Brian Cox acknowledges the importance of the Apollo moon landings in inspiring him, and many like him, to take up careers in science - so what will the next big scientific inspiration be?
