NASA's 2 astronauts conduct the all-female spacewalk, a first in space history
NASA astronauts Christina Koch and Jessica Meir conduct an all-female spacewalk, for the first time in space history. They step outside the International Space Station to replace a failed power controller. The faulty power regulator was in operation since 2000 and failed to activate after new lithium-ion batteries were installed. The first all-female space walk was originally scheduled to take place in March.
