NASA astronauts Christina Koch and Jessica Meir completed the first all-female spacewalk last week. The historic moment came 35 years after Kathryn Sullivan became the first American woman to spacewalk. We hear from Koch, Meir, and Sullivan. And former NASA chief scientist Ellen Stofan tells us why she says this moment is long overdue. Follow host Maddie Sofia on Twitter @maddie_sofia.
