Voyager’s Return. Season 1, Episode 6. First broadcast Thursday 9 October 1975.

This month, John and Victor decide that the pursuit of a shoebox full of polaroids is a good reason to risk the crew’s lives — entrusting their safety to this week’s guest star, a Nazi rocket scientist or something with a secret past that inevitably involved killing a whole bunch of people in an easily foreseeable accident. However, things hot up with the arrival of three steatopygous spaceships captained by a heavily-made up alien with no facial expression, who is understandably resolved to kill everyone on the base and all the loved ones they left behind them.
