Fifty years ago Sputnik was launched by the Russians, and the space age dawned. Starting with the jubilation, fear and panic that accompanied the launch of "The Red Moon", this documentary explores how satellites have now affected almost every aspect of our lives.
Spy satellites and GPS (global positioning system) have transformed the military. Communications have been revolutionized, with Telstar, the first commercially-launch satellite, even becoming an international celebrity. Satellites have revolutionized our understanding of our climate, saving countless lives. Hubble, so nearly a disaster, went on to change the way we understand our universe. Thanks to satellites, the world is now a smaller, safer, and better understood place.
The programme explores the technological milestones that have made all this possible but ends with a warning. Our civilization 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.
