Today in 1992, NASA launched the Space Shuttle Endeavor (its second trip). It was also the 50th mission of the Space Shuttle program. While the mission itself was mostly for experimentation, it is notable for three of its crew members: Mae Jemison, who became the first African-American woman in space (and the subject of a previous Today Years Ago), and Mark Lee and Jan Davis, the first married couple in space. As married couples were previously banned from being crew members of the same flight, Lee and Davis secretly married a few months before the launch. NASA didn’t have enough time to cancel or alter the mission, so it was ultimately allowed. This led to much speculation among the press and general public about their potential sexual relations in space. Not amused, NASA quickly explained that it would be nearly impossible to have sex in zero gravity anyway. To this day, Lee and Davis (now divorced) have not commented on whether or not they “did the deed” in space.
