The Satellite Story (2007 BBC documentary)

The Satellite Story is a 2007 BBC documentary celebrating the 50th anniversary of the first satellite, Sputnik, which launched the space age in 1957. Spy satellites and GPS (global positioning system) have transformed the military. Communications have been revolutionised, with Telstar, the first commercially-launch satellite, even becoming an international celebrity. Satellites have revolutionised our understanding of our climate, saving countless lives. The film explores the technological milestones that have made all this possible but ends with a warning. Our civilisation is now dependent on satellites, making us vulnerable were something to go wrong. Recent events in China have revealed just how vulnerable we might be, for they suggest we might be on the verge of another new age - of satellite terrorism.

How to Build a Satellite

Some of the best and most up-to-date communication satellites in the world are designed and built in Stevenage in Britain. With exclusive access to specialist manufacturer Astrium, this film shows step-by-step how to assemble one of the most complicated machines in the world.

The team is followed as they construct a massive communication satellite; from the inner carbon-fibre skeleton to the fuel tanks and engines. At the Portsmouth site, the electronic 'payload' is built and then tested. It has to operate for a minimum of fifteen years - guaranteed, and so precision is everything; these machines are built inside rooms cleaner than the cleanest operating theatre. Once the satellite is built and tested, it is sent to France where solar arrays and antenna dishes are added before it is boxed up and sent for launch in French Guiana in South America.
