Korzun performed two spacewalks during his six-month stay aboard the ISS. On 16 August 2002 Korzun performed his third career spacewalk together with NASA astronaut [[Peggy Whitson]].<ref>{{cite web |url=http://65.165.5.234/centers/johnson/news/station/2002/iss02-36.html |title=International Space Station Status Report #02-36 |author=NASA |date=August 16, 2002 |accessdate=June 10, 2010}}</ref> The two spacewalkers got off to a late start because they evidently forgot to open an oxygen valve in their Russian [[Orlan space suit|Orlan]] spacesuits while getting prepared and the [[Pirs (ISS module)|''Pirs'']] docking compartment airlock had to be re-pressurized. Once the valves were set correctly, Korzun reported a pressure leak but the Russian officials declared it as a no issue. By the time the hatch was finally opened almost two hours had been wasted and the spacewalk was cut short to a duration of 4.5 hours. The objective of the spacewalk was to fortify the ISS against damaging space debris. Korzun and Whitson installed six debris panels onto the [[Zvezda (ISS module)|''Zvezda'']] Service Module. They removed the panels from their temporary location on the station's [[Pressurized Mating Adapter|PMA-1]] prior to attachment to ''Zvezda''. The panels are designed to shield ''Zvezda'' from potential space debris impacts. The spacewalk lasted 4 hours and 25 minutes.
Korzun performed his fourth career spacewalk on 26 August 2002.<ref>{{cite web |url=http://www.space.com/missionlaunches/exp5_eva2_020826.html |title=Russian Cosmonauts Complete Spacewalk at International Space Station |author=Jim Banke |publisher=SPACE.com |date=August 26, 2002 |accessdate=June 10, 2010 |deadurl=yes |archiveurl=https://web.archive.org/web/20090523132327/https://www.space.com/missionlaunches/exp5_eva2_020826.html |archivedate=May 23, 2009 |df= }}</ref> The start of the spacewalk was delayed because of an air leak in the sealed hatches between the Pirs airlock and the ''Zvezda'' module. The problem was easily corrected but took Korzun and [[Sergei Treshchov]] almost a half-hour to step through the procedures and get ready to go outside. Despite the late start at 05:27 UTC, the two spacewalkers finished everything assigned to them on this spacewalk.<ref>{{cite web |url=http://65.165.5.234/centers/johnson/news/station/2002/iss02-36.html |title=International Space Station Status Report #02-38 |author=NASA |date=August 26, 2002 |accessdate=June 10, 2010}}</ref> Wearing Russian Orlan spacesuits Korzun and Treshchov installed a frame on the outside of the [[Zarya (ISS module)|''Zarya'']] module to house components for future spacewalk assembly tasks. They installed new material samples on a pair of Japanese Space Agency materials exposure experiments housed on the outside of ''Zvezda''. They installed devices on ''Zvezda'' that will simplify the routing of tethers during future assembly spacewalks. The two spacewalkers also improved future station amateur radio operations by adding two ham radio antennas on ''Zvezda''. The spacewalk was staged from the ''Pirs'' docking compartment airlock and lasted 5 hours and 21 minutes.
