Ep 24. The Junkyard of Space

The Jupiter must land, to repair a fuel tank that is causing fires. But first, someone must explore a cosmic cloud with the space pod to verify the Jupiter can pass through it. Smith draws the short screwdriver, but talks the Robot into taking his place. Then a magnetic force captures the Robot and hauls him to a space "junk yard" run by a bizarre robot junk man. Then a strange form of rust plague infects the Robinsons' food supply, forcing Smith to trade parts from the robot to the junk man in exchange for meals. But when the junk man has what he wants, he plans to cut off the food and steal the Jupiter, stranding the Robinsons on his own wretched world!
