unprofitable, especially since the show was syndicated, rather than being broadcast by a major network.) Today, all 39 episodes of the TV series are available for viewing on YouTube. Episodes Thirty-nine 30-minute episodes were filmed and shown during the period starting in February, 1954, and running into January, 1955, depending on the local market schedule. Thirty-six of these were grouped into 12 three-chapter, 30-minute story arcs, and three were completed in a single, 30-minute episode each. Most of the three-chapter story arcs were edited into feature-length movies for television, and of those some were renamed (see guide below): Two of the edited movies, Manhunt in Space and Crash of the Moons, were lampooned on the cult hit comedy show Mystery Science Theater 3000. All of the episodes are available on DVD (and the obsolete VHS format). See also Space Cadet, the 1948 science fiction novel by Robert A.
