First All-Female Spacewalk Scheduled For Later This Week

NASA astronauts Christina Cook and Jessica Mirror are set to make history with the first all-female spacewalk. Scheduled for later this week, it will be Mirror's first and Cook's fourth spacewalk. The mission involves replacing a faulty battery charge-discharge unit on the International Space Station. A previous all-female spacewalk was planned but canceled due to a lack of suitable space suits. This event is significant as only 14 women have participated in spacewalks, always accompanied by men. If successful, Mirror will become the 15th woman to perform a spacewalk.
