In January 1991, a couple of crazy kids got married. That these particular “kids” were in their late 30s, were astronauts, and were keeping their marriage a secret from their bosses at NASA only added to the romance. Mark Lee and Jan Davis met during training for a space shuttle mission and kept their relationship quiet long enough to ensure that it would be difficult to replace them on the mission, as NASA normally would have done under its then-unwritten rule that banned married astronauts from flying together. And so, in September 1992, Lee and Davis became the first (and, after the unwritten rule became a written one, possibly last) married couple in space.
America had just one question for them. You know. Eh? Eh? Wink-wink.
NASA says no humans have had sex in space. There’s nothing other than speculation to suggest otherwise. (Well, speculation and a vague sense that we would want to try it, given half a chance.) But you aren’t a total junior-high pervert for wondering. Sex — or, rather, reproduction — has piqued the curiosity of scientists, too. When they went to space together, Lee and Davis even spent some time artificially inseminating frog eggs for the greater good. (So, somebody got lucky on that trip. Sort of.)
