The first-ever all-female spacewalk in history has been cancelled due to a lack of suitable spacesuits. <br />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. <br />However, their mission was called off as NASA says only one medium-sized spacesuit was available,... the size that best fits both astronauts. <br />While the spacewalk will go ahead as scheduled,... a male astronaut will carry out the mission instead of McClain. <br />
