“For All Mankind” showrunner Ronald D. Moore gave some insight into the inspiration behind the female astronauts in the upcoming Apple TV series during the Variety and Apple TV Plus Collaborations panel, explaining that the women in the series are based on a real group of women who were part of the Mercury 13 NASA Program. The original group of women went through the same training as the male Mercury 7 group, but never made it to the moon.

“That program got canceled before they ever actually took flight training,” he said. “So part of our premise was to go back and revisit who were the Mercury 13 and where would they be. When NASA decides they want to put women into the program, there’s a specific story point where NASA says ‘Where are our female astronauts?’ ‘Why does Nixon want to put women on the moon?’ ‘Where do we find them?'”
