We don't change a winning team: astronauts Jessica Meir and Christina Koch made a new spacewalk this Wednesday from the International Space Station (ISS). It is the second 100% female spacewalk in history.
The two astronauts again braved the space vacuum to change parts of the ISS. The station's old nickel-hydrogen batteries were replaced by new lithium-ion batteries in an operation that lasted six and a half hours.
An increasingly feminine NASA
Jessica Meir and Christina Koch will do another outing next Monday to start the operation again. At the moment, the current crew of the ISS is made up of the two women as well as the American Andrew Morgan, the European astronaut Luca Parmitano, and the Russian cosmonauts Alexander Skvortsov and Oleg Skripochka.
The first outing of the two women, on October 18, was a real event: the more than 200 previous outings always included at least one man. NASA has greatly feminized its body of astronauts. The latest promotion consists of five women and six men, joined by a Canadian and a Canadian, who are carrying out their initial training with the American space agency.
