NASA: Humanity's envoys: After Voyager 2, its faster twin Voyager 1 completes 45 years in space

Voyager 1 was launched in 1977 on a Titan IIIE-Centaur rocket. The probes are powered by radioisotope thermoelectric generators (RTGs) they generate electricity using the heat produced by the decay of plutonium. It is expected to cross the Oort cloud in the next few hundred years.
