French astronaut Sophie Adenot leads third spacewalk in all-female ISS excursion

French astronaut Sophie Adenot is conducting her third spacewalk in two weeks, leading a rare all-female excursion outside the International Space Station. The main task is to replace a retroreflector, a device that helps modules align when docking with the station. The excursion is expected to last six to six and a half hours and is only the sixth all-female spacewalk in space history.
