The first all-female spacewalk is scheduled for this morning at the International Space Station.
American astronauts Christina Koch and Jessica Meir will put on their spacesuits to replace malfunctioning battery components connected to the station's solar power system.
It's a big milestone for NASA. Of the 38 active astronauts, only 12 are women.
It’s set to begin at 6:50am CST – you can watch NASA’s live coverage ↓
