The first-ever all-female spacewalk in history has been cancelled due to a lack of suitable spacesuits.
Astronauts Christina Koch and Anne McClain who have been in training for six years,... were scheduled to walk outside the International Space Station on March 29th, on a mission to replace batteries.
However, their mission was called off as NASA says only one medium-sized spacesuit was available,... the size that best fits both astronauts.
While the spacewalk will go ahead as scheduled,... a male astronaut will carry out the mission instead of McClain.
