The 1st All-Woman Spacewalk: Photos, Videos and Celebratory Tweets

NASA astronauts Christina Koch and Jessica Meir ventured outside the International Space Station early this morning (Oct. 18) to embark on the first spacewalk in history to be conducted entirely by women. 

The spacewalking duo, who trained together in the same astronaut class, aren't just colleagues — they're best friends, too. And today they're making history together as they work outside the orbiting laboratory on an unplanned spacewalk to repair a battery charge/discharge unit on one of the solar arrays that failed after Koch and NASA astronaut Nick Hague replaced a battery during a spacewalk on Oct. 11

We will post updates here throughout the day, with the latest photos, videos and celebratory tweets, so be sure to check back later for the latest news from the first all-women spacewalk!
