NASA cancels all women spacewalk due to lack of spacesuits
New Delhi : Sadly, NASA has scrapped the pre-planned spacewalk mission by two women astronauts, due to lack of spacesuits that would fit them at the International Space Station. The space agency has re-scheduled the task which is likely to be performed in coming Friday.
Astronaut Christina Koch will now perform tasks in space Friday with her colleague American Nick Hague. Earlier, Anne McClain was considered to walk along side Christina, but not the plan has changed. If Koch and McClain would have done their spacewalk together, it would have been the first ever by two women astronauts.
Till date, male-only or mixed male-female teams had conducted spacewalk since the space station was assembled in 1998.
McClain worked outside the station last week with Hague, when she realized that a "medium"-sized upper half of her spacesuit fit her better.
"Because only one medium-size torso can be made ready by Friday, March 29, Koch will wear it," NASA explained.
The spacesuits aboard the ISS are in fact assemblies of several parts put together as best adapted to each astronaut's body, explained Brandi Dean, spokeswoman of the Johnson Space Center in Houston, Texas where American astronauts are based.
She said two upper parts in each of the three available spacesuit sizes are currently held at the ISS: medium, large and extra large.
"We do our best to anticipate the spacesuit sizes that each astronaut will need, based on the spacesuit size they wore in training on the ground, and in some cases astronauts train in multiple sizes," she said in explaining the problem that hampered Friday's spacewalk plan.
"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.
"In addition, no one training environment can fully simulate performing a spacewalk in microgravity, and an individual may find that their sizing preferences change in space."
