War of the Space Giants - S1.E5

From Republic's press release: ""The Ruler has found an element on the planet Saturn that enables him to drop germ capsules through the Cosmic Dust Blanket onto the Earth."" The Ruler uses his M-7 rockets loaded with bombs which carry germ warfare agents. The Ruler issues and ultimatum: complete surrender or complete annihilation. Cody captures an unexploded M-7 and analysis indicates that the substance is ""saturium,"" available only one of Saturn's moons. Cody, Joan and Dick travel to the moon and encounter a ""magnetic drag ray."" They manage to counteract the ray and destroy the mining facility on the surface.
