NASA's first women-only spacewalk, to replace ISS equipment, is finally happening

15 that the third in a series of battery replacement spacewalks that had been scheduled for October 16, featuring NASA astronauts Jessica Meir and Andrew Morgan, had been postponed after a device called a battery charge/discharge unit, or BCDU, failed on the station over the weekend.

NASA is still ironing out the details of Koch and Meir's spacewalk but the two are expected to venture out of the ISS on either October 17 or October 18 at 7:50 am EDT.

After an infamous spacesuit flub earlier this year that resulted in accusations of sexism, Nasa now plans to carry out the first all-female spacewalk this week, it said yesterday.

Astronauts Christina Koch and Jessica Meir will take part in the giant leap for womankind on October 21 when they venture out of the International Space Station (ISS) to install new batteries.

The International Space Station generates power using solar panels but batteries are required when the space lab is in the dark and not receiving any sunlight. During the first five spacewalks, crew members will upgrade existing nickel-hydrogen batteries on a port truss with more powerful lithium-ion batteries. The balky charger is 19 years old; the one that failed in the spring was nearly as old. "We don't believe that's the case, but we want to go take some time and look at all the data".

The current situation is "manageable, but again not something that we would want to live with in the long term", Todd told reporters. Koch helped assemble an extra medium suit over the summer. Very good that we now have four expert spacewalkers on board to shoulder this robust task. "They are the A-team!" tweeted astronaut Anne McClain, who would have gone spacewalking with Koch in March if not for the suit-sizing issue.

Just 15 women have ever conducted a spacewalk, and all of them did so with a male companion. Meir and Christina Koch's October 21 spacewalk will be the first all-female spacewalk.

While all four - two men and two women - are equally trained for the fix job, Koch and Meir are the right choices given the future spacewalking workload, officials noted.
