Are We Alone - "Humans in Space... ace... ace"
When the economy's down, will humans still be going up - into space, that is? We investigate the future of human spaceflight at the International Astronautical Congress in Glasgow, Scotland and find out whether sending Homo sapiens to the Moon and Mars is still a good idea. Also, the chief of Virgin Galactic is happy to send you into space on a private flight - but it may max out your credit card.
Plus, an Apollo astronaut's view from orbit... dining with South Korea's first astronaut... and one of Britain's great science fiction authors on how space science fuels the imagination.
