Vladimir Dezhurov - Cosmonaut Career - Spacewalks

Spacewalks

During his cosmonaut career, Dezhurov has performed nine spacewalks. During Mir EO-18 long duration mission Dezhurov together with cosmonaut Gennady Strekalov conducted five spacewalks. As of June 2010, his nine spacewalks totalling 37 hours and 2 minutes has placed him in the 25th position in the list of astronauts who have the most extra-vehicular activity (EVA) time.

On 12 May 1995, Dezhurov conducted his first career spacewalk. The spacewalk started 04:20:44 UTC and ended at 10:35:16 UTC. He and Strekalov prepared for the arrival of the Spektr module and prepared to move Kristall's solar panel. They also practiced work at the Kristall module. The spacewalk lasted 6 hours and 14 minutes.

Dezhurov performed his second career spacewalk on May 17. They moved the solar array to the Kvant-1 module. The spacewalk lasted six hours and 52 minutes.

On May 22, Dezhurov and Strekalov installed the solar array on Kvant-1 and stowed Kristall's other solar array. The excursion out of the Mir Space Station marked Dezhurov's third career spacewalk. The spacewalk started at 00:10:20 UTC and was completed at 05:25:11 UTC. The spacewalk lasted 5 hours and 14 minutes.

On 28 May and June 1, 1995, Dezhurov and Strekolov conducted two spacewalks to prepare Mir to move Kristall and Spektr modules. Dezhurov's fourth and fifth career spacewalks lasted 21 and 23 minutes respectively.

Dezhurov conducted another four spacewalks during the Expedition 3 mission to the ISS. On October 8, 2001, Dezhurov and Tyurin ventured outside of the ISS to mark the 100th spacewalk to be carried out by Russian cosmonauts. The main objective of the spacewalk was to outfit the Pirs Docking Compartment and make connections between that newly arrived compartment and the Zvezda module. The spacewalkers installed a cable that allows space walk radio communications between the two station sections. They also installed handrails on the new compartment and an exterior ladder that will be used to help spacewalkers leave Pirs' hatch. Dezhurov and Tyurin also installed a Strela cargo crane onto the station. The spacewalk lasted 4 hours and 58 minutes ending at 19:21 UTC.

On October 15, 2001, Dezhurov performed his seventh career spacewalk. The two spacewalkers returned to space outside the ISS from the Pirs airlock. Dezhurov and Tyurin installed Russian commercial experiments on the exterior of Pirs. Among the experiments is a set of investigations of how various materials react to the space environment over a long time. Called MPAC-SEEDS, the investigation is housed in three briefcase-sized containers. The spacewalk lasted 5 hours and 52 minutes.

On November 12, 2001, Dezhurov conducted his eighth career spacewalk. Dezhurov and NASA astronaut Culbertson connected cables on the exterior of the Pirs Docking Compartment for the Kurs automated docking system. They completed checks of the Strela cargo crane, using one space walker at the end of the crane's boom to simulate a cargo. They also inspected and photographed a small panel of one solar array on the Zvezda Service Module that has one portion of a panel not fully unfolded. The spacewalk was conducted in Russian Orlan spacesuits. It lasted 5 hours and 4 minutes.

On December 3, 2001, Dezhurov conducted his ninth career spacewalk. Dressed in Orlan spacesuits, Tyurin and Dezhurov floated out of the Pirs airlock at 13:20 UTC. Dezhurov and Tyurin used a cutting tool to remove an errant rubber seal that had prevented a Progress resupply ship from firmly docking with the ISS. The two spacewalkers also took pictures of the debris, which was a rubberized seal from the previous cargo ship, and of the docking interface. The spacewalk lasted 2 hours and 46 minutes.
