U.S. astronauts Patrick G. Forrester and Steven R. Swanson conducted a fourth unscheduled spacewalk outside the ISS, to wrap up incomplete tasks. During the spacewalk, which lasted 6 hours and 29 minutes, Forrester and Swanson completed their primary task of activating the SARJ, a rotating joint on the ISS’s new power module; installed a new camera stanchion on the S3 Truss; and linked a computer-network cable between the U.S. and Russian sides of the stations. The two astronauts were unable to bolt down the debris shields that Commander Fyodor N. Yurchikhi and Flight Engineer Oleg V. Kotov had installed on the Zvezda module during the spacewalk on 6 June. Instead, they opted to tether the two panels in place.
