"We are doing our best to predict the size of the suit that any astronaut will need, based on the size of the suits he wore on the ground training, and in some cases, the astronauts." , individual size changes may change when they are in orbit, in response to the changes that live in microgravity can lead to the body, "she added.
So far only male or mixed male and female teams are conducted space transitions
