Farmer in The Sky

Farmer In The Sky is a 1953 science fiction novel by Robert A. Heinlein about a teenaged boy who emigrates with his family to Jupiter's moon Ganymede, which is in the process of being terraformed. A condensed version of the novel was published in serial form in 1950 in Boys' Life magazine (August, September, October, November 1950), under the title "Satellite Scout". The copyright page of the first edition hardcover published by Charles Scribner's Sons states "Copyright 1950 by Robert A. Heinlein", noting the publication of the earlier condensed Boy's Life version, but the title page of the first edition hardcover states "1953, New York, Charles Scribners Sons". The novel was awarded with the Retro Hugo in 2001.

Passing references by the lead character to the song "The Green Hills of Earth" three times and to its author, Rhysling, once, have caused some to consider it part of Heinlein's "Future History" series.
