between ISS and Atlantis. Later on the day they reviewed the timeline for next day's spacewalk. Mission Specialists James Reilly, John Olivas, Steven Swanson and Patrick Forrester spent time working on the U.S. spacesuits. Olivas and Reilly finished their post-spacewalk spacesuit reconfiguration tasks, while Forrester and Swanson configured their suits and tools for EVA 4. The shuttle and space station crew also spoke with reporters during a space-to-ground news conference. Earlier in the day, flight controllers in Moscow issued commands to restart some systems in the Russian segment of the space station. During the day computer problems on the ISS were further resolved, with all six processors available (four online and two standby). Following the successful attempt to revive four channels on flight day 8 after bypassing what appeared to be a faulty power switch with external cabling, cosmonauts Fyodor Yurchikhin and Oleg Kotov repeated that same modification on the last two channels. June 17 (Flight day 10 – EVA 4) The crew's wakeup call went up at 6:38 am CDT. Flight day 10 saw the successful completion of the mission's final spacewalk by Patrick Forrester and Steven Swanson. The fourth spacewalk of STS-117 began at 16:25 UTC. Astronaut James Reilly choreographed the activity from Atlantis' flight deck shadowed by station Flight Engineer Oleg Kotov serving as the intravehicular crew member. EVA 4 was the 87th in support of station assembly and maintenance, 11th spacewalk completed in 2007, the 59th staged out of the ISS and the 36th out of the Quest airlock. Swanson and Forrester retrieved a TV camera and its support structure from a stowage platform attached to the Quest Airlock and installed it on the S3 truss. They then verified the Drive Lock Assembly (DLA) 2 configuration and removed the last six SARJ launch restraints. The two astronauts cleared the path on the S3 truss for the Mobile Base System by removing temporary rail stops and hardware that had secured the S3/S4 truss segments in the shuttle's payload bay. The work completed the major tasks assigned for the STS-117 mission. The pair then began some of the get-ahead tasks mission managers had hoped to complete. The two spacewalkers installed a computer network cable on the Unity node that was to permit astronauts in the U.S. segment of the station to command systems in the Russian segment and opened the Hydrogen vent valve on the Destiny laboratory installed
