The 2 astronauts who had been scheduled to stroll collectively in area on Friday, Anne C. McClain and Christina H. Koch, would each must put on a medium-size torso part. However just one is available on the Worldwide Area Station.

The mission itself is unchanged. On Friday, two astronauts will enterprise exterior of the area station on a six-hour mission to put in large lithium-ion batteries that may assist to energy the analysis laboratory. Ms. Koch remains to be scheduled to take part, alongside together with her fellow astronaut Nick Hague; Ms. McClain did her first spacewalk final week.

However the first women-only enterprise exterior of the confines of the area station should occur on one other day. “After consulting with McClain and Hague following the primary spacewalk, mission managers determined to regulate the assignments, due partially to spacesuit availability on the station,” NASA stated in a assertion.

Stephanie Schierholz, a spokeswoman for NASA, stated in an interview on Monday that there have been already two medium-size arduous higher torsos — “primarily the shirt of the spacesuit,” in accordance with NASA — on the area station.

However there have been a few points. One was that Ms. McClain had thought she would be capable to work in a large-size torso, however after her spacewalk final Friday, she wore a medium-size torso and realized that it match her higher. Ms. Koch additionally makes use of the identical dimension.

And of the 2 medium-size torsos accessible, one has but to be correctly configured for a spacewalk. It will take hours of crew labor — to not point out some extra threat — to repair that in time for Friday. As an alternative of doing that, NASA determined to easily swap out the astronauts.

In the long run, each ladies can have achieved a spacewalk — simply not collectively.

“When you’ve got the choice of simply switching the folks, the mission turns into extra essential than a cool milestone,” Ms. Schierholz stated.

In a briefing at NASA’s Johnson Area Heart in Houston this month, Ms. Lawrence, Ms. Kagey and Kenneth Todd, the station’s operations integration supervisor, stated officers had not instantly acknowledged the importance of the unique lineup for Friday’s “extravehicular exercise,” or EVA.

It was solely as they mentioned the schedule throughout a gathering that they realized it was the primary time they’d scheduled an all-female spacewalk.

After the rescheduling on Monday, Ms. Schierholz stated that whereas there have been no concrete plans for an all-female spacewalk, one is more and more doubtless as a result of NASA astronauts have been diversifying when it comes to gender.

“We’re kind of attending to the purpose of inevitability,” Ms. Schierholz stated of an all-female EVA.

Ms. McClain and Ms. Koch had been a part of the 2013 astronaut class, and of the eight folks in that class — chosen from greater than 6,000 candidates — half had been ladies, a primary for NASA. The company lists 38 energetic astronauts on its web site, and 12 are ladies.

The batteries being put in on this mission retailer solar energy that the station wants when it’s not in direct daylight. Work on the battery methods will proceed for the following few years as worldwide groups carry extra lithium-ion batteries to the station, which is greater than 200 miles from Earth.

The missions require meticulous planning, and robots do as a lot of the work as attainable earlier than astronauts take the danger of venturing into area. Within the busy days forward of a spacewalk, the crew assist to organize and match their colleagues’ spacesuits, which operate as mini-spacecraft as soon as they step exterior.

Ms. Koch shared pictures on Twitter of her colleagues as they suited up for final Friday’s spacewalk.

“No abnormal battery swap & work day routine,” she wrote.
