The First All-Female Spacewalk Is Happening Today
The first all-female spacewalk is happening today outside the International Space Station. At 7:38 AM ET, astronauts Jessica Meir and Christina Koch exited the airlock, and the walk is scheduled to last for five or six hours. The first spacewalk for Meir and the fourth for Koch, the two astronauts will be replacing the station’s faulty power regulator, which has been in operation since 2000. While it isn’t the first time a woman has participated in a spacewalk, it is the first time a group composed of all women has done so.
