The initial concept for the series followed the scripts by
Joseph Greene originally proposed as a comic strip in 1945, and then as a proposed radio serial in 1946, titled "Space Cadets" (with a young hero named Tom Ranger), and 1947, titled "Space Academy". When Greene began work with Rockhill Studios on developing his idea into a television show in 1949, the title
Tom Ranger, Space Cadet was floated for a time. In 1950, Rockhill Studios licensed the "Space Cadet" name from
Robert A. Heinlein's 1948 young-adult novel
Space Cadet for the series then in development. == Cast ==
