Two NASA astronauts replaced a broken antenna on the ISS during a spacewalk Thursday. Astronauts Thomas Marshburn and Kayla Barron spend six hours and 32 minutes outside the station, successfully replacing a malfunctioning S-band antenna on the station's truss with a backup. The two completed that work ahead of schedule, allowing them to perform a few additional "get-ahead" tasks before heading back inside the station. The spacewalk was the first for Barron and the fifth for Marshburn who, at age 61, is now the oldest person to have walked in space.
