NASA pulls off women's spacewalk for lack of tight clothing


Christina Koch will now perform assignments in space on Friday with fellow American Nick Hague – instead of Anne McClain as originally planned.

If Koch and McClain had made the space walk together, it would have been the first of all the two female astronauts.

So far, male or mixed teams of men and women had driven the space walk since the space station was set up in 1998 – 214 spacewalks so far.

McClain worked out of the station last week – with the Hague – when he realized that a top half of his "average" space suit fit her best.

"As only a medium-sized trunk can be prepared on Friday, March 29, Koch will use it," NASA explained.

Space suits aboard the ISS are actually assemblies of various parts that best fit the body of each astronaut, said Brandi Dean, a spokesman for the Johnson Space Center in Houston, Texas, where American astronauts are based.

She said that two tops in each of the three available sizes of space suits are currently on the ISS: medium, large and extra large.

"We do our best to anticipate the spacecraft sizes each astronaut will need, based on the size of the spacecraft used in the training and in some cases, the astronauts train in various sizes," she said in explaining the space walk problem .

"However, the sizing needs of individuals may change when they are in orbit, in response to the changes that live in microgravity can cause in a body.

"Furthermore, no training environment can fully simulate performing a microgravity space walk, and an individual may find that their size preferences change in space."
