This edition looks at Britain's attempt to become a major player in the modern space race. From Scotland's wild northern shore, where Britain's first spaceport is planned, to the team planning Britain's new rocket system, the programme explores the technology behind a quiet revolution in Britain's space industry. Driving the resurgence of 'space Britannia' is a new breed of spacecraft - micro-satellites. As many as 12,000 of them will be built and launched worldwide over the next decade, and Britain is aiming for a slice of the action. Also, guest presenter Tim Peake celebrates Britain's past achievements in space and finds out where it all went wrong.
