NASA brings forward all-female spacewalk

An all-female spacewalk outside the International Space Station (ISS) will take place this week rather than next, NASA said on Tuesday.
Astronauts Christina Koch and Jessica Meir will venture outside the orbiting laboratory to replace a power controller that failed during the weekend, the US space agency said.
The spacewalk, the first by two women, is planned for Thursday or Friday.
Managers of the ISS decided to bring forward the all-female spacewalk so the women can replace the faulty power unit. The decision means other spacewalks slated to take place this week and next to replace batteries have been postponed.
The failed unit has no impact on the crew’s safety or ongoing experiments, but does prevent a new lithium-ion battery installed earlier this month from providing additional power, NASA said in a blog post.
Though the lithium-ion batteries are not yet fully functional, the station’s overall power supply, fed by four sets of batteries and solar arrays, remains sufficient for all operations, NASA said in the blog post.
NASA originally scheduled the first all-female spacewalk for late March but had to cancel it because of a lack of spacesuits in the right size.
