They?ve Got Spacesuits that Fit Now. Christina Koch and Jessica Meir Will Spacewalk on October 21st

   10 Oct 00:00:09  |  Universe Today

The all-female astronaut walk is back on. Back on March 26th, 2019, NASA was forced to cancel the first all-female spacewalk because they didn’t have the right spacesuits available on the ISS.
