He was a member of two missions to the International Space Station, spending more than a year in total in space. During his missions he did three spacewalks lasting more than 18 hours in total.

Personal
Volkov is the first second-generation cosmonaut (and space walker), the son of cosmonaut Aleksandr Volkov. He was born on April 1, 1973 in Chuguyev, Kharkov Region, Ukraine. Volkov and his wife Natalia have a son who was born in 2001. His recreational activities include tennis, windsurfing, reading, and visiting museums.

Education
Volkov graduated from Star City high school in 1990 and entered the Tambov Air Force Academy for Pilots. He graduated in 1995 with a degree of pilot/engineer.

Awards
Volkov was awarded the Hero of the Russian Federation medal and Russian Federation Armed Forces medals.

Experience
After graduating from Tambov Air Force Academy, Volkov served in the air force as an assistant aircraft commander. He has mastered the Aero L-29 and L-39, the Ilyushin Il-22, and the Tupolev Tu-134, and has also accumulated 450 flight hours. He is a Class 3 military pilot.

Cosmonaut career
From December 1997 to November 1999, Volkov underwent general cosmonaut training, and in November 1999, was qualified as a test cosmonaut. Since January 2000, he has been part of a group of test cosmonauts training for missions to the International Space Station (ISS).

From August 2001 to February 2003, Volkov trained as part of the Expedition 7 backup crew as a Soyuz-TMA Commander and ISS Flight Engineer. From March 2003 to December 2004, he trained as part of the Expedition 11 primary crew for launch on the Space Shuttle. From January 2005 to February 2006, he trained as part of a group of test cosmonauts for missions to the ISS. In February 2006, he was appointed as a member of the Expedition 13 backup crew and Visiting Crew 10 as a Soyuz TMA Flight Engineer 2 and an ISS Visiting Crew Flight Engineer.

Expedition 17
In June 2006, he was appointed a member of the Expedition 17 prime crew as Soyuz TMA Commander and ISS Commander. The Soyuz TMA-12 spacecraft carrying Volkov along with fellow cosmonaut Oleg Kononenko and South Korean spaceflight participant Yi So-Yeon blasted into space on April 8, 2008. Volkov served as the commander of the ISS expedition 17. He is the youngest ISS commander to date. His mission lasted from April to October 2008.

Volkov, Kononeko and space tourist Richard Garriott, the son of astronaut Owen K. Garriott returned to Earth aboard Soyuz TMA-12 on October 24, 2008. Garriott is the first second-generation American space explorer. The spacecraft landed at 03:36 GMT 55 miles north of Arkalyk, Kazakhstan. Later they were lifted to the Kazakhstan Baikonur Cosmodrome by helicopter and then flown to Zvezdny Gorodok (Star City) in Moscow.

Expedition 28/29
On June 7, 2011 (UTC), Volkov returned to space aboard Soyuz TMA-02M to join the crew of Expedition 28.

Spacewalks
Volkov conducted his first spacewalk on July 10, 2008 when he ventured into space from the Pirs docking compartment airlock of the ISS. He and cosmonaut Kononenko inspected their Soyuz TMA-12 spacecraft and retrieved a pyro bolt from it. The spacewalk lasted 6 hours and 18 minutes and Volkov served as the lead spacewalker.

On July 15, 2008 Volkov together with Kononenko again went outside from Pirs to conduct a spacewalk. The two spacewalking cosmonauts installed one experiment and retrieved another. They also continued to outfit the station's exterior, including the installation of a docking target on the Zvezda service module. The spacewalk was in Russian Orlan suits and Volkov, as the lead spacewalker wore the suit with red stripes. This spacewalk lasted 5 hours and 54 minutes.

Russian EVA #28
On August 3, 2011 Volkov participated in his third spacewalk. He and cosmonaut Aleksandr Samokutyayev worked for six hours and 23 minutes performing a variety of tasks for both science and maintenance outside the Russian segment of the ISS. Outside the Zvezda service module, Volkov and Samokutyayev installed laser communications equipment. They also, photographed an antenna with signs of degraded performance. After ground controllers took time to work on an antenna problem, the two cosmonauts also deployed a small satellite named Radioskaf-V which was originally planned for deployment at the beginning of the spacewalk. The satellite contained an amateur radio transmitter and a student experiment. The primary task of the spacewalk the relocation of the Strela 1 boom from the Pirs module to the Poisk module, had to be called off due to time constraints. The cosmonauts removed an antenna that helped guide the Poisk module to a docking in November 2009 and was returned to the ISS at the end of the spacewalk. They also successfully installed the materials science experiment - BIORISK on a handrail outside the Pirs module. BIORISK experiment studies the effect of microbes on spacecraft structures and whether solar activity affects microbial growth. Finally, Volkov and Samokutyayev took more photographs holding photos of the first cosmonaut Yury Gagarin, spacecraft designer Sergei Korolyov and Soviet astronautic theory pioneer Konstantin Tsiolkovsky with Earth in the background before entering the Pirs module, closing the hatch and completing the Russian EVA #28.

Lawsuit with Yuri Gagarin Cosmonaut Training Center
In February Russian Government excluded Yuri Gagarin Cosmonaut Training Center from the list of organizations served by military officers. All military personnel serving as cosmonauts were forced to retire from military service and become civilian specialists at significantly lower rates of pay (the premium for military officers working as cosmonauts was between 55% and 120% of their nominal salaries). Sergey Volkov successfully sued Yuri Gagarin Cosmonaut Training Center, winning back 1,382 Russian roubles (approximately $40,000) in lost pay.
