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.
