Space Cadet is a 1948 science fiction novel by Robert Heinlein about youngsters who join the patrol that keeps the peace in the solar system. From the space academy with a blind (but not unseeing) commandant to lessons in using a powered space suit, from discussions on ethics and responsibility to lessons in math and foreign cultures, this is a very believable schoolboy tale. Tex and his friends avert possible war with the Venusians with some deft cultural maneuvering when a former schoolmate provokes the otherwise peace-loving matriarchical society of Venus.
