Vagina MuseumSally Ride was the first American woman and first lesbian in space, first flying in 1983. Before she flew, NASA weren't really sure what a woman in space might need, so suggested providing her with 100 tampons. For a six day mission.
Ride's first space flight took place more than 20 years after cosmonaut Valentina Tereshkova became the first woman in space. Part of NASA's delay in sending a woman to space was that they were worried menstrual blood would flow backwards in microgravity, wreaking all sorts of havoc.
(incidentally, sometimes period blood *does* flow backwards into the pelvic cavity. It turns out that this is usually perfectly harmless, more on retrograde menstruation here:) https://masto.ai/@vagina_museum/111381001900415323
