Hard to imagine why this show (the first ever German ScFi series) lasted less than three months. In English, the title was Space Patrol Orion. Here's Wikipedia:
Raumpatrouille – Die phantastischen Abenteuer des Raumschiffes Orion (literal translation: Space Patrol – The Fantastic Adventures of the Spaceship Orion), also known as Raumpatrouille Orion, and Space Patrol Orion in English, was the first German science fiction television series.
First episode date: September 17, 1966
Final episode date: December 10, 1966
