NASA astronauts Jessica Meir and Christina Koch participated in their third spacewalk together, three years after they made history by completing the first all-female spacewalk. Christina Koch can be seen shooting a short picture in Jessica Meir's helmet mirror as her crewmate completes upgrading the electrical systems on the ISS's Port-6 truss.
