The Solarnauts Unsold Pilot: Cloud of Death (made 1967) sample frame from video
This unaired pilot is an outer space adventure about a police-like organization that patrols our Solar System, made in the UK by Roberta Leigh, whose previous work had been with puppets in series such as "Space Patrol" (shown in the US as "Planet Patrol").
In this episode, after a strange cloud destroys a research station on Mars, an alien named Logik threatens to obliterate the Martian capital city unless the authorities hand over the mining rights to the entire planet. Solarnaut Chief Tri-S assigns the nearest patrol vessel, crewed by Power and Tempo, to investigate the region in the Asteroid Belt from which the ultimatum was transmitted. They meet Kandia, a meteorite researcher who was marooned on a barren asteroid after Logik destroyed her research station.
