Space Cadet (Ace Books, May 1971). Cover by Davis Meltzer
A book with the title Space Cadet is a little hard to take seriously; not many people can help thinking of the slang meaning. But it wasn’t used that way when Heinlein wrote it in 1948. If some people didn’t take it seriously, it was because science fiction as such wasn’t taken seriously — but Heinlein himself was quite serious about it.
In fact his novel was the first public use of the phrase, though it became better known after the television show Tom Corbett, Space Cadet bought the right to use it from him in 1950 — enough so that in 1953, Porky Pig appeared in Duck Dodgers in the 24th 1/2 Century as an “eager young space cadet.” The expression might have suggested youth and naiveté, but not being out of touch with reality.
