PPE fit isn't rocket science... NASA has canceled their first all-women spacewalk because there aren't enough properly sized space suits to make it happen. "According to NASA, the astronauts learned that they wear the same size spacesuit, but only one of those sizes will be available by March 29." "And of the two medium-size torsos available, one has yet to be properly configured for a spacewalk. It would take hours of crew labor — not to mention some additional risk — to fix that in time for Friday. Instead of doing that, NASA decided to simply switch out the astronauts." https://lnkd.in/eTZpJPj
