If astronauts have had space sex, it would have been very difficult. First off, there isn’t much privacy up there. A regular shuttle is about as big as a 737, and the two main areas are each the size of a small office. The bathroom is little more than a seat with a curtain, and there aren’t any closed rooms where two people could retreat. The space station, on the other hand, has a little more room to operate. The three-person crew generally splits up for sleeping time: Two of them bed down in a pair of tiny crew cabins at one end of the station, and the third might jump in a sleeping bag at the other end, almost 200 feet away. (The panel-and-strap design of a space bed might not be that conducive to lovemaking.) Astronauts also have a demanding work schedule, leaving them with little time or energy for messing around. Space-station crews do get time off on weekends, though, when they can watch movies, read books, play games, “and generally have a good time.”

Astronaut Lisa Nowak is facing attempted murder charges after she drove nearly 1,000 miles to confront a rival for the affections of another astronaut, Bill Oefelein. Nowak said that she and Oefelein had “more than a working relationship, but less than a romantic relationship.” Wait, did they ever get it on in space?
No. Nowak and Oefelein were never on the same mission, so they couldn’t possibly have joined the 62-mile-high club. But some of their colleagues may well have engaged in some extraterrestrial hanky-panky. Former and current astronauts don’t like to talk about space-shuttle sex, and NASA says that if it’s ever happened, the agency doesn’t know anything about it. (NASA has never conducted official experiments on animal reproduction in space, says a spokesman.)
