Satellite Science Fiction was an American science-fiction magazine published from October 1956 to April 1959 by Leo Margulies' Renown Publications. Initially, Satellite was digest sized and ran a full-length novel in each issue with a handful of short stories accompanying it. The policy was intended to help it compete against paperbacks, which were taking a growing share of the market. Sam Merwin edited the first two issues; Margulies took over when Merwin left and then hired Frank Belknap Long for the February 1959 issue. That issue saw the format change to letter size, in the hope that the magazine would be more prominent on newsstands. The experiment was a failure and Margulies closed the magazine when the sales figures came in.
