NASA's first all-woman spacewalk is making history


Today marks NASA’s 221st spacewalk performed as part of the process of space station assembly, but it is totally groundbreaking for one reason: it is the first spacewalk conducted entirely by women. NASA astronauts Jessica Meir and Christina Koch are making history today! For Meir, it’s her first spacewalk ever, and according to NASA, she has become the 15th woman ever and the 14th U.S. woman to spacewalk. 

That is a big deal! Their spacewalk is being broadcast live and you can watch it right on Twitter.
