Menace From Outer Space (1956)

To summarize the Rocky Jones show - Jones (Richard Crane) is a space-ship captain who flies around the solar system with an improbably named sidekick "Winky" (played by ill-fated child prodigy Scotty Beckett) representing the United Worlds - an interplanetary political entity which has a very strong resemblance to Star Trek's federation. Also like Star Trek - the Rocky Jones series also consistently cast women in positions of considerable power and responsibility - a bold move for 1950s TV. Like later series from the Star Trek franchise, the show also employs pseudo-scientific black-box technologies and technobabble quite liberally in order to avoid plot holes and speed bumps on the highway of logic.
