Bon Voyager

Voyager 1 left Earth 40 years ago, on September 5th, 1977. Voyager 2 left first, on August 20th. Amazingly, both are still functioning. They are getting ever closer to the edge of the solar system.
51 years ago Star Trek premiered in Sept 1966, 3 seasons, 79 episodes. Low Nielsen ratings killed it, but it became a hit in syndication, then a cult classic from which every other space tv program and movie grew.
