Ghost Station

An artificial planetoid is heading straight for Earth on a collision course, so the Rangers and the ambassadors got try to stop it. A highly sophisticated computer is running the show, and its a horror picture. Using holography, SPECK (the computer) is trying to drive them off with one ghost story after another. Everybody splits into teams (horror movie mentality) to see who can get to the control room first. It seems SPECK was programmed by some long dead alien race, and can't get out of him programming. He doesn't want to hit Earth, but has no choice. Doc "helps" him to self destruct before he can do any damage, and they sadly say good-bye. This episode highly resembles Scooby Doo in a warped way....
