Space ranger

David Starr, Space Ranger is the first novel in the Lucky Starr series, six juvenile science fiction novels by Isaac Asimov that originally appeared under the pseudonym Paul French. The novel was written between 10 June and 29 July 1951 and first published by Doubleday & Company in January 1952. Since 1971, reprints have included an introduction by Asimov explaining that advancing knowledge of conditions on Mars have rendered some of the novel's descriptions of that world inaccurate. The novel was originally intended to serve as the basis for a television series, a science-fictionalized version of The Lone Ranger, but the series was never made, in part because another series called Rocky Jones, Space Ranger was already in the planning stages.
