A planned first all-female spacewalk has been cancelled because of spacesuit issues, US space agency Nasa says. Anne McClain and Christina Koch had been scheduled to install lithium-ion batteries at the International Space Station (ISS) on Friday. But Nasa says there is only one ready medium-size hard upper torso spacesuit that fits best each of the two women. Ms Koch will now conduct Friday's spacewalk with her male colleague Nick Hague, the space agency says.
"However, individuals' sizing needs may change when they are on orbit, in response to the changes living in microgravity can bring about in a body," she added.
Space is a harsh environment that affects the body in many ways. In microgravity, bone loss occurs at a rate of 1 to 1.5 percent a month, leading to an acceleration of age-related changes similar to osteoporosis. Decreases in bone density and strength are more pronounced in some skeletal regions, such as the pelvis, although much of the loss is reversible upon return to Earth. Prolonged exposure to weightlessness also increases the risks of kidney stones and bone fractures, which are both associated with bone demineralization.
There is space for two full Extravehicular Mobility Units (EMUs), one short EMU, and two Orlan space suits (Russian equivalent to the EMU) aboard the ISS. They are stored in the Joint Airlock. Since the spacesuits are not part of the emergency plan, they do not store one for every astronaut (let alone a backup for each).

NASA once again is covering up the truth.
The suits fit perfectly but when they came out of their rooms and realised they had the same outfit on all hell broke loose.
