Sally Ride’s tampons might be the most-discussed tampons in the world. Before Ride became the first American woman in space, scientists pondered her tampons, weighed them, and NASA’s professional sniffer smelled them—better to take deodorized or non-deodorized?—to make sure they wouldn’t smell too strongly in a confined space capsule. Engineers considered exactly how many she might need for a week in space. (Is 100 the right number?, they famously asked her. No, Ride said. That is not the right number.)
The engineers were trying to be thoughtful, though; reportedly they packed the tampons with their strings connected so that they wouldn’t float away. […]
Before women went into space, there were not only the sadly typical concerns that women would become weepy or unable to function during their periods, but also that the menstrual cycle might somehow break in space. Would the blood come out without gravity to pull it from the womb? Maybe it would all pool up in there, or even flow backward through the fallopian tubes into the abdomen—a frightening condition called retrograde menstruation.
In the end, someone just had to try it and see what happened. And what happened was … nothing much. The uterus is pretty good at expelling its lining sans gravity, it turns out.
