Do astronauts carry on, um, "personal relationships" in outer space? "We don't have them and we won't," STS-131 shuttle commander Alan Poindexter is quoted as saying in today's Telegraph. Poindexter's statement, made during a Tokyo visit, simply reiterates the no-talking-about-sex-in-space stance often heard from NASA. On Earth, it's a different story, of course: Astronauts get married to each other (such as current space station resident Shannon Walker and Mir veteran Andrew Thomas). They even have affairs (as astronauts Lisa Nowak and Bill Oefelein famously did). Oefelein, by the way, is still slated to marry Colleen Shipman, the third member of that astronaut love triangle, in August.
