Astronauts Christina Koch and Jessica Meir carried out history’s first all-female spacewalk Friday, floating outside the International Space Station and successfully installing a 230-pound replacement battery charger in the lab’s solar power system.
The spacewalk began at 7:38 a.m. EDT when Koch, making her fourth excursion, and Meir, making her first, switched their spacesuits to battery power inside the Quest airlock, kicking off 221st station spacewalk since assembly began in 1998. It was the first by two women in the 54 years since the first “extra-vehicular activity,” or EVA, by a Russian cosmonaut in 1965, sparking widespread public interest.
Despite the unusual level of scrutiny, Friday’s spacewalk was a strictly-business affair to replace a faulty 232-pound battery charger in the lab’s solar power system. Any two of the space station’s four NASA sponsored astronauts could have done the work — they all received similar training — but Koch and Meir got the nod.
