Spacers were the fictional first humans to emigrate to space in Isaac Asimov's ''Foundation'' and related ''Robot'' and ''Empire'' series. In these stories, about a millennium thereafter, they severed political ties with Earth, and embraced low population-growth and extreme longevity (with lifespans reaching 400 years) as a means for a high standard of living, in combination with using large numbers of robots as servants. At the same time, they also became militarily dominant over Earth. Asimov's novels chronicle the gradual deterioration of the Spacer worlds, and the disappearance of robots from human society. The exact details vary from book to book, and in at least one case—the radioactive contamination of Earth—later scientific discoveries forced Asimov to retcon his own future history. The general pattern, however, is as follows: In the vague period between Asimov's near-future ''Robot'' short stories (of the type collected in ''I, Robot'') and his novels, immigrants from Earth establish colonies on fifty worlds, the first being Aurora, the last Solaria, and the Hall of the Worlds located on Melpomenia, the nineteenth. Sociological forces possibly related to their sparse populations and dependence on robot labor lead to the collapse of most of these worlds; their dominance is replaced by new, upstart colonies known as "Settler" worlds. Unlike their Spacer predecessors, the Settlers detested robots, and so by the time of the ''Empire'' novels, robotics is almost an unknown science. Roger MacBride Allen's ''Caliban'' trilogy portrays several years in the history of Inferno, a planet where Spacers recruit Settlers to rebuild the collapsing ecology. In ''Foundation and Earth'', Golan Trevize visits several of these worlds. We learn the eventual fate of Aurora (''The Robots of Dawn'') and also Solaria, the setting of the earlier novel ''The Naked Sun''. ==Known Spacer worlds== Although Asimov never issued a full list of the fifty Spacer worlds, some of them can be inferred from the author's novels and short stories. Some of them are: * Acrisia (from Mark W. Tiedemann's ''Mirage'') * Aurora * Capella (from Mark W. Tiedemann's ''Chimera'') * Euterpe * Faunus * Hesperos * Inferno (from Roger MacBride Allen's ''Caliban'' trilogy) * Keresia (from Mark W. Tiedemann's ''Chimera'') * Melpomenia * Nexon * Osiris (from Mark W. Tiedemann's ''Chimera'') * Pallas * Pallena (from Mark W. Tiedemann's ''Mirage'') * Proclas * Rhea * Saon (from Mark W. Tiedemann's ''Mirage'') * Smitheus * Solaria * Tethys * Theia (from Mark W. Tiedemann's ''Chimera'') 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Spacer (Asimov)」の詳細全文を読む スポンサード リンク
