Two Russian cosmonauts in Orlan spacesuits wrapped up a 8-hour, 7-minute spacewalk to attempt the installation of photographic equipment on the exterior of the International Space Station at 4:07 p.m. EST Friday.
Commander Oleg Kotov and Flight Engineer Sergey Ryazanskiy promptly completed the main objective of Friday's spacewalk - the installation of a pair of high-fidelity cameras as part of a Canadian commercial endeavor designed to downlink Earth observation imagery -- but had to remove them later due to an unspecified problem that prevented telemetry from being received on the ground by Russian flight controllers.
Because of the issue in activating the cameras, Kotov and Ryazanskiy did not have time to complete the all of their planned tasks, which included the jettisoning of a frame that once held three Micro-Particles Capturer and Space Environment Exposure Device (MPAC & SEED) units for a Japanese space exposure study and the installation of a payload boom.
Friday's spacewalk eclipsed the record for the longest Russian spacewalk set by Expedition 36 Flight Engineers Fyodor Yurchikhin and Alexander Misurkin, who conducted a 7-hour, 29 minute excursion on Aug. 16.
