Space Patrol

The first, and most well known, is the American version from the 1950s.

The second is a puppet series from the UK, made in 1962, featuring the vocal talents of Dick Vosburgh, Ronnie Stevens, Libby Morris, Murray Kash and Ysanne Churchman. It concerns an interplanetary police force of the year 2100, focussing on the crew of Galasphere 347 under the command of Captain Larry Dart. This series is also known by its US title 'Planet Patrol' to avoid confusion with the first series.

The third is a translation from the German, 'Raumpatrouille' (aka 'Raumschiff Orion' or 'Spaceship Orion'), and was a 7 part space opera made in 1966. At the time it was the most expensive show ever made in the country, a major factor in the series not continuing! It did, however, spawn over a hundred follow-up novels and is as fondly remembered in Germany as 'Star Trek' is in the US and UK.
