Washington: In a historic first, National Aeronautics and Space Administration astronauts Christina Koch and Jessica Meir embarked on the first all-women spacewalk on Friday.
Koch and Meir walked outside the International Space Station to replace a faulty battery unit.
As NASA astronauts Christina Koch and Jessica Meir emerged one by one, it marked the first time in a half-century of spacewalking that a woman floated out without a male crew-mate.
Although it is the 221st spacewalk performed yet it's the first to be conducted entirely by women astronauts.
"The first all-woman spacewalk is a milestone worth noting and celebrating as the agency looks forward to putting the first woman and next man on the Moon by 2024 with NASA's Artemis lunar exploration program," the NASA website read.
Previously, the spacewalk also known as the astronauts Koch and Meir were set to do the first-ever all-women spacewalk on October 21.
