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 revolutionised, with Telstar, the first commercially-launch satellite, even becoming an international celebrity. Satellites have revolutionised 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.
