 (ISS) on June 7, 2002 at 16:25 UTC. Korzun joined the Expedition 5 crew as the commander. Expedition 5 crew carried out approximately 25 new investigations onboard the ISS, as well as continued with various science investigations begun before their stay. The scientific investigations aimed at studying cold plasma, crystal growth, radiation effects in the space and the human body. Some medical experiments involved blood, muscles, bones while the crew also conducted psychological experiments. Korzun also participated in ecological experiments and monitored the Earth's surface from space. Earth observation from outer space has many useful applications including informing the ground of disaster situations such as fires and floods as quickly as they occur.

 mission. The shuttle touched down at KSC Runway 33 at 19:38:25 UTC. Completing his second long duration spaceflight, Korzun logged 184 days and 22 hours in space.


Korzun has performed four career spacewalks. During the Mir EO-22 mission he performed 2 spacewalks totaling 12 hours and 33 minutes. During ISS Expedition 5, he again performed two spacewalks totalling 9 hours and 46 minutes.

On December 2, 1996, Korzun performed his first career spacewalk with cosmonaut Aleksandr Kaleri. The main purpose was to complete connections of the cooperative solar array to provide more electrical power to the Mir station. The spacewalk started at 15:54 UTC and ended at 21:52 UTC lasting 5 hours and 57 minutes. During the spacewalk, the two cosmonauts installed MCSA cables.

Korzun performed his second career spacewalk on December 9, 1996. The main purpose was to complete connections of the cooperative solar array to provide more electrical power to the Mir station. He and Kaleri completed the MCSA cable installation and attached a Kurs docking antenna. The spacewalk started at 13:50 and ended at 20:28 lasting 6 hours and 38 minutes.

Korzun performed two spacewalks during his six-month stay aboard the ISS. On August 16, 2002, Korzun performed his third career spacewalk together with NASA astronaut Peggy Whitson

. The two spacewalkers got off to a late start because they evidently forgot to open an oxygen valve in their Russian Orlan spacesuits while getting prepared and the 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 Service Module. They removed the panels from their temporary location on the station's 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 August 26, 2002. 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. Wearing Russian Orlan spacesuits Korzun and Treshchov installed a frame on the outside of the 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.
