NASA Cancels First All-Female Spacewalk Over Spacesuit Sizes - The New York Times
It hadn’t been planned as a historic mission, yet it would have represented a moment of sorts: the first all-female spacewalk.
But that moment will have to wait, NASA said Monday, because of a somewhat basic issue — spacesuit sizes.
The two astronauts who were scheduled to walk together in space on Friday, Anne C. McClain and Christina H. Koch, would both need to wear a medium-size torso component. But only one is readily available at the International Space Station.
