Reception
Boucher and McComas praised the 1950 edition as Heinlein "at his superlative best".[1] In his "Books" column for F&SF, Damon Knight selected The Man Who Sold the Moon as one of the 10 best science fiction books of the 1950s.[2]P. Schuyler Miller said that "Heinlein is a master of concealed technology ... no other writer [has] worked out the scientific minutiae of his settings so fully or so unobtrusively", praising as well Heinlein's skill at crafting "the human engineering details of each situation".[3]
