Washington, D.C: National Aeronautical Space Administration (NASA) is facing the accusation of propagating sexism after it cancelled first women space walk.
The two female McClaine and Christina Kosh were supposed to make their space walk as first women space walk on March 29.
"Because only one medium-size torso can be made ready by Friday, March 29, Koch will wear it", NASA confirmed in a statement.
Aboard the ISS the spacesuits are several parts assembled in order for each astronaut to have they suit adapted to their body, according to the explanations provided by a spokeswoman of the Johnson Space Center in Houston, Texas, Brandi Dean, where American astronauts are based.
The spacewalk will go ahead on Friday, but Ms Koch will now be accompanied by her male colleague Nick Hague, rather than Ms McClain. Andre specializes in environmental health, but writes on a variety of issues.

Boeing's newest aircraft - were grounded worldwide after two fatal accidents in five months raised questions over its safety . He said if this was the case, then the team would issue a recommendation to the Boeing Company the aircraft's manufacturer.
Earlier this month, Facciol, the lead flight controller, tweeted her support for an all-female spacewalk. Both Hague and Saint-Jacques take large. This is partly due to the effects of microgravity, or weightlessness. The other suits, which are considered backups, can't be pulled out and used immediately, and they must be prepped for use in space. That extra space inside the suit can be less noticeable when working in Earth's 1-gravity environment. "For example, temperature is controlled through a rotary dial on the front of the EMU, which means smaller astronauts face visual and mechanical disadvantages that limit their ability to properly control suit temperature".
Further complicating the matter, astronauts often grow taller while in space. Koch, who has a background in electrical engineering and physics, will launch into space on March 14 and join McClain at the ISS.
It is easy for women to change dresses even at the last minute before going out if something doesn't fit right.
McClain certainly isn't the first woman to face problems with spacesuit sizes. However, to reduce spending, the agency ended up developing only three sizes (medium, large and extra large), which would fit most astronauts.
