The episode The Lost Children featured a space ship. This episode was released on December 3, 1983.

The party helps a group from another world to recover the space ship which has been captured by Venger. The crew of the ship are a child-like race with some strange stripes on their skin. They also have a wookie-like mechanic. I think they say they are from the Planet Axon, but its hard to make out the name.

The vessel looks more like it could be related to Expedition on Barrier Peaks, or Dave Arneson's City of the Gods, but I don't recognize the races.
