The idea of sex in space appears frequently in science fiction. Arthur C. Clarke claimed to first address it in his novel "Rendezvous with Rama" (1973). Among films that include space-sex themes are "Moonraker", "Moving Violations", "Supernova" and "". In the novelization of "Alien", Parker tells Brett about an episode of zero-G sex that went wrong. A more recent and perhaps more realistic description of the mechanics of low-gravity intercourse is presented in "Sex in Space: The Video", a short story contained in Susie Bright's "The Best American Erotica 2004". The story uses cheating astronauts to describe techniques humans might use to copulate in space without special apparatus. The difficulties microgravity poses for human intimacy were also discussed in an anonymous fictional "NASA Document 12-571-3570" in 1989, where the use of an elastic belt and an inflatable tunnel were proposed as solutions to these problems. A mission patch and other documents were determined to be hoaxes.
