NASA's first all-female spacewalk has an official date, and you can watch it unfold live. 

Astronauts Christina Koch and Jessica Meir will head out on a spacewalk to replace a power controller that failed over the weekend.

Koch and Meir are scheduled to exit the International Space Station on Friday, Oct. 18 at 7:50 AM ET. NASA will livestream the event on NASA Live starting at 6:50 a.m. ET that day.

Earlier this week, NASA announced the spacewalk would take place on Thursday or Friday. It was initially scheduled for Monday. 

Originally, the first all-female spacewalk was to take place in March. It had to be postponed after properly fitting spacesuits weren’t ready in time for Koch and astronaut Anne McClain.
