"Space Patrol" (a.k.a. "Planet Patrol" for U.S. release) was a children's cartoon show with puppet marionettes. The concept was an interplanetary organization of men and women from Earth, Mars and Venus, patrolling the Solar System to maintain the peace in the year 2100.
What distinguished this series from others of its ilk was the thought that went into it. The characters had real personalities. The futuristic Headquarters City was well done despite the cheap budget, with individual personal vehicles traveling thru transparent tubes to be automatically guided to their final destination. The spaceship wasn't the usual rocket ship, but something innovative: a "Galasphere" that looked vaguely like a kid's gyroscope toy, that made weird humming sounds as it sailed thru space. (Those humming sounds became the theme song for the TV series.)
The plots and sets were surprisingly dark for a children's show, in the style of "Outer Limits." One plot concerned aliens from Neptune (I think) conspiring to take over the minds of Earthlings and eventually "conquer the Earth leaders". Another dealt with a plot to subvert Earth's currency by counterfeiting huge quantities of Earth money. Even the backdrops were dark--the sky over the Headquarters City was usually dark, dreary overcast rather than bright and sunny.
Could have been a great show with a bigger budget.
