NASA’s first all-female spacewalk cancelled
Astronauts Anne C. McClain and Christina H. Koch were meant to conduct a spacewalk on March 29, supported by an all-female crew on Earth.
NASA does not have enough space suits that fit the women to safely complete the space walk, so they have replaced McClain with astronaut Nick Hague.
Spacesuits are made up of many pieces, and both female astronauts required a medium-sized torso component, of which only one was available at the space station.
According to the NASA website, assembling a spacesuit is not a simple task, and two different suits with many pieces in proper sizes are needed.
Astronauts usually wear an orange spacesuit in the shuttle during launch and landing, and for time spent outside, astronauts wear an EMU (extravehicular mobility unit) spacesuit, designed to function as a personal spacecraft for the user.
