context_page_description: Oleg Valeriyevich Kotov was born on October 27, 1965, in Simferopol, Crimean oblast in the Ukrainian SSR. After a career as a physician assigned to the Soviet space program, he joined the Russian cosmonaut corps. He has flown two long duration spaceflights on the International Space Station logging just short of a year in space. Most recently, Kotov flew on the Soyuz TMA-10M/Expedition 37/Expedition 38 long duration spaceflight, from September 2013 until March 2014.
context_section_description: On 30 May 2007 at 19:05 GMT, accompanied by Fyodor Yurchikhin, Kotov began his first spacewalk, lasting 5 hours and 25 minutes, during which they installed protective panels to shield the ISS from space debris.
  On June 6, 2007, Kotov performed his second spacewalk from the Pirs docking compartment airlock. Along with Yurchikhin, Kotov installed a section of Ethernet cable on the Zarya module, installed additional Service Module Debris Protection (SMDP) panels on Zvezda, and deployed a Russian scientific experiment. The two cosmonauts returned to the ISS at 4:00 p.m. EDT to wound up the 5 hours, 37 minutes spacewalk.
  On January 14, 2010, Kotov again ventured outside the ISS with fellow Russian cosmonaut Maksim Surayev to begin his third spacewalk. The spacewalking duo connected cables between the Poisk and Zvezda modules, installed docking targets and Kurs aerials and attached additional handrails to exit hatches. The spacewalk lasted 5 hours and 44 minutes.
  On 9 November 2013, Kotov performed his fourth spacewalk outside the ISS with Sergey Ryazansky.
  They took the Olympic torch for the 2014 Winter Olympic Games outside ISS. They also continued work on an extravehicular activity workstation and biaxial pointing platform by removing launch brackets and bolts, as well as retrieving an experimental package. The planned installation of a foot restraint on the mounting seat of the workstation was deferred to a future spacewalk after the spacewalkers noticed some issues with its alignment. The spacewalk lasted 5 hours 50 minutes.
  On 27 December 2013, Kotov and Ryazansky were outside of the ISS to perform a spacewalk. The cosmonauts attached two (high and medium resolution) cameras as part of a commercial agreement between a Canadian firm and the Russian Federal Space Agency to provide Earth views to internet-based subscribers. Kotov routed the data and telemetry cables for the medium resolution camera, however, flight control team at the Russian Mission Control Center did not see the expected telemetry and electrical connectivity from the cameras. Eventually, the cosmonauts were instructed to remove the cameras and return them back inside the ISS for further analysis.  In addition to the camera installation work,  Kotov and Ryazansky also removed and jettisoned the Vsplesk experiment package designed to monitor seismic effects using high-energy particle streams in the near-Earth environment. The spacewalkers next attached the more sophisticated earthquake-monitoring Seismoprognoz experiment to a Zvezda handrail. The spacewalk lasted 8 hours and 7 minutes and extended the record for the longest Russian spacewalk set by Expedition 36 cosmonauts Fyodor Yurchikhin and Alexander Misurkin, who conducted a 7-hour, 29 minute spacewalk on 16 August 2013.
  On 27 January 2014, Kotov did perform his sixth spacewalk outside the ISS with cosmonaut Ryazansky. The cosmonauts completed work that could not be finished up during their last spacewalk on December 27. After exiting the Pirs docking compartment, the two cosmonauts arrived at the outside of the Zvezda service module. They then installed a high resolution camera and a medium resolution camera to capture Earth imagery, however the medium resolution camera again experienced telemetry issues. Kotov and Ryazansky also removed a cassette container attached to the Pirs docking compartment, installed earlier as part of a materials exposure experiment. They also removed a worksite interface adapter attached to a portable data grapple fixture on the Zarya module to ensure that future operations with the Canadarm2 robotic arm will not be disrupted. The spacewalk marked the fourth EVA conducted during the Expedition 38 and lasted six hours and eight minutes.
