Satellite Science Fiction was an American science fiction magazine, published from October 1956 to April 1959 by Leo Margulies' Renown Publications. It was edited initially by Sam Merwin, then Margulies, and finally Frank Belknap Long. In addition to a handful of short stories, initially each issue ran a full-length novel, including the original version of Philip K. Dick's first novel The Cosmic Puppets, and well-received work by Algis Budrys and Jack Vance, though the quality was not always high. Isaac Asimov, Arthur C. Clarke, and L. Sprague de Camp were among the short story contributors. Sam Moskowitz wrote a series of articles on the early history of science fiction for Satellite; these were later to be revised as part of his book Explorers of the Infinite. In 1958 Margulies tracked down the first magazine publication of H.G. Wells' The Time Machine from 1894–1895, and reprinted a short excerpt from it that had been omitted by every subsequent printing.
