"“There is the problem of designing and fitting a spacesuit to accommodate their particular biological needs and functions,” explained one NASA official during the fall of 1960. The Apollo spacesuit, added another spokesperson more than a decade later, “would be damaging to the soft structures of the feminine body.” There was also the issue of bodily waste. By the mid-1960s the space agency had already spent millions of dollars developing a urinary collection device that slid over each crewman’s penis, but the female anatomy, NASA administrators claimed, presented additional engineering difficulties in the weightlessness of space. “There was no way to manage women’s waste,” argued NASA’s Director of Life Sciences, David Winter. “If you can’t handle a basic physiological need like that, you can’t go anywhere.” The national media became obsessed with this particular issue, publicizing NASA administrators’ concerns to the broader American public."
