CAPE CANAVERAL, Fla. (CLARKSVILLENOW) – Move over men, space walk No. 421 belongs to the women. On Friday, Oct. 18 NASA astronauts Christina Koch and Jessica Meir venture outside the International Space Station for a spacewalk. The team will exit the station’s Quest airlock in their U.S. spacesuits to replace a power controller that failed over the weekend.

NASA began the live stream of the mission earlier Friday morning, around 6:30 a.m. with the spacewalk starting at about 7:50 a.m. EDT.

Dubbed by NASA as “HERstory in the making” they’re asking schoolteachers to share photos of students celebrating the historic moment. The pictures might end up on the spacewalk broadcast.
