NASA Astronauts Conduct the First "All Woman Spacewalk"
NASA astronauts Christina Koch and Jessica Meir made "HERstory," as NASA is calling it, with the first all-female spacewalk. All four men aboard the International Space Station remained inside, as Koch and Meir went out to replace a broken battery charger.
The battery charger failed after Koch and a male crewmate installed new batteries outside the space station last week. NASA put the remaining battery replacements on hold to fix the problem and moved up the women's planned spacewalk by three days.
Meir, a marine biologist who arrived at the orbiting lab last month, is the 15th female spacewalker. Koch, an electrical engineer, already had done three spacewalks; she's seven months into an 11-month spaceflight that will be the longest by a woman.
NASA planned the first all-female spacewalk in March, but had to call it off because of a shortage of medium-size suits. Koch put together a second medium over the summer.
