Farmer In The Sky is a 1950 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 Boys' Life magazine, under the title "Satellite Scout". The novel was awarded a Retro Hugo in 2001.
Passing references by the lead character to the song "The Green Hills of Earth" and to its author, Rhysling, have caused some to consider it part of Heinlein's Future History series.
