This is a list of crew to the International Space Station , in alphabetical order. Current ISS crew names are in bold. The suffix (twice, thrice, ...) refers to the individual's number of spaceflights to the ISS, not the total number of spaceflights. Entries are noted with for women and
for men.
This list only includes crew members of the ISS. For a list including non-crew, see List of visitors to the International Space Station.
Yuri Ivanovich Malenchenko is a retired Russian cosmonaut. Malenchenko became the first person to marry in space, on 10 August 2003, when he married Ekaterina Dmitrieva, who was in Texas, while he was 240 miles (390 km) over New Zealand, on the International Space Station. As of December 2023, Malenchenko ranks third for career time in space due to his time on both Mir and the International Space Station (ISS). He is a former commander of the International Space Station.
Yury Valentinovich Lonchakov is a Russian former cosmonaut and a veteran of three space missions. He has spent 200 days in space and has conducted two spacewalks. From 2014 to 2017, Lonchakov served as head of the Yuri Gagarin Cosmonaut Training Center.
Scott Joseph Kelly is an American engineer, retired astronaut, and naval aviator. A veteran of four space flights, Kelly commanded the International Space Station (ISS) on Expeditions 26, 45, and 46.
Fyodor Nikolayevich Yurchikhin is a Russian cosmonaut of Pontic Greek descent, engineer and RSC Energia test-pilot who has flown on five spaceflights. His first spaceflight was a 10-day Space Shuttle mission STS-112. His second was a long-duration stay aboard the International Space Station (ISS) as a flight engineer for Expedition 15; for this mission he was launched in the Soyuz TMA-10 spacecraft. He has undertaken two further long-duration stays aboard the ISS, as a crew member of Expedition 24 / 25. For this mission he was launched with the spacecraft Soyuz TMA-19, and he landed in November 2010, also with the Soyuz TMA-19 spacecraft. He served as Soyuz commander for his fourth mission aboard Soyuz TMA-09M, as flight engineer for Expedition 36 and ISS commander for Expedition 37. In April 2017, Yurchikhin launched on Soyuz MS-04 for the fifth spaceflight of his career, a six-month mission to the ISS as part of Expedition 51 and 52, for which he was the commander.
Expedition 15 was the 15th expedition to the International Space Station (ISS). Four crew members participated in the expedition, although for most of the expedition's duration only three were on the station at any one time. During Expedition 15, the ISS Integrated Truss Structure was expanded twice: STS-117 brought the S3/S4 truss, and STS-118 brought the S5 truss.
Shannon Walker is an American physicist and a NASA astronaut selected in 2004. She launched on her first mission into space on June 25, 2010, onboard Soyuz TMA-19 and spent over 163 days in space.
Soyuz TMA-13 was a Soyuz mission to the International Space Station (ISS). The spacecraft was launched by a Soyuz-FG rocket at 07:01 GMT on 12 October 2008. It undocked at 02:55 GMT on 8 April 2009, performed a deorbit burn at 06:24, and landed at 07:16. By some counts, Soyuz TMA-13 is the 100th Soyuz spacecraft to be crewed.
Expedition 18 was the 18th permanent crew of the International Space Station (ISS). The first two crew members, Michael Fincke, and Yuri Lonchakov were launched on 12 October 2008, aboard Soyuz TMA-13. With them was astronaut Sandra Magnus, who joined the Expedition 18 crew after launching on STS-126 and remained until departing on STS-119 on 25 March 2009. She was replaced by JAXA astronaut Koichi Wakata, who arrived at the ISS on STS-119 on 17 March 2009. Gregory Chamitoff, who joined Expedition 18 after Expedition 17 left the station, ended his stay aboard ISS and returned to Earth with the STS-126 crew.
Soyuz TMA-15 was a crewed spaceflight to the International Space Station. Part of the Soyuz programme, it transported three members of the Expedition 20 crew to the space station. TMA-15 was the 102nd crewed flight of a Soyuz spacecraft, since Soyuz 1 in 1967. The Soyuz spacecraft remained docked to the space station during Expedition 20 and Expedition 21 as an emergency escape vehicle. The mission marked the start of six-person crew operations on the ISS.
Soyuz TMA-17 was a human spaceflight mission to the International Space Station (ISS). TMA-17 crew members participated in ISS Expedition 22 and Expedition 23. The mission ended when the Soyuz TMA-17 capsule landed on 2 June 2010.
NASA Astronaut Group 16 was a group of 44 astronauts announced by NASA on May 1, 1996. The class was nicknamed "The Sardines" for being such a large class, humorously implying that their training sessions would be as tightly packed as sardines in a can. These 44 candidates compose the largest astronaut class to date. NASA selected so many candidates in preparation for the anticipated need for ISS crew members, along with regular shuttle needs. Nine of the 44 astronauts selected were from other countries including 5 from Europe and 2 from Canada and Japan.
Soyuz TMA-20 was a human spaceflight to the International Space Station (ISS) and was part of the Soyuz programme. It lifted off from the Baikonur Cosmodrome in Kazakhstan on December 15, 2010, and docked with the ISS two days later. The three-person crew of Soyuz TMA-20 – Dmitri Kondratyev, Catherine Coleman and Paolo Nespoli – represented the ISS partner organizations of Roscosmos, NASA and the European Space Agency (ESA). Soyuz TMA-20's crew represented half of the members of Expedition 27; the other three members of the expedition arrived at the station on board Soyuz TMA-21 on April 6, 2011. The COSPAR ID of Soyuz TMA-20 was 2010-067A. It is ISS flight 25S.
Expedition 26 was the 26th long-duration mission to the International Space Station. The expedition's first three crew members – one US astronaut and two Russian cosmonauts – arrived at the station on board Soyuz TMA-01M on 10 October 2010. Expedition 26 officially began the following month on 26 November, when half of the crew of the previous mission, Expedition 25, returned to Earth on board Soyuz TMA-19. The rest of the Expedition 26 crew – one US astronaut, one Russian cosmonaut and one ESA astronaut – joined the trio already on board when their spacecraft, Soyuz TMA-20, docked with the station on 17 December 2010.
Expedition 24 was the 24th long-duration mission to the International Space Station (ISS). Expedition 24 initially had two planned spacewalks, one Russian and one American Extra-vehicular Activity (EVA). The U.S. EVA was re-planned and a second U.S. EVA was added.
Expedition 27 was the 27th long-duration expedition to the International Space Station (ISS), starting on 16 March 2011. Expedition 27 saw numerous notable events, including the undocking of the Progress M-09M and Kounotori 2 spacecraft, the arrival of the Soyuz TMA-21 and Progress M-10M spacecraft, and the final rendezvous with the ISS of NASA's Space Shuttle Endeavour, on its last mission, STS-134. The expedition ended on 23 May 2011 with the departure of the Soyuz TMA-20 spacecraft, although command of the station was ceremonially handed over to the crew of Expedition 28 on 22 May.
Expedition 28 was the 28th long-duration expedition to the International Space Station, and began on 23 May 2011 with the departure of the members of Expedition 27. The first three members of Expedition 28 arrived on the ISS aboard the Soyuz TMA-21 spacecraft on 4 April 2011, and were joined on 9 June 2011 by the three other crew members, who arrived aboard Soyuz TMA-02M. The expedition saw a number of significant events, including the final Space Shuttle mission, STS-135, which took place in July 2011. Expedition 28 was superseded by Expedition 29 on 16 September 2011.
Soyuz TMA-22 was a crewed spaceflight to the International Space Station (ISS). TMA-22 was the 111th flight of a Soyuz spacecraft, and transported three members of the Expedition 29 crew to the ISS. The spacecraft docked to the ISS on 16 November 2011, and remained docked to serve as an emergency escape vehicle until its undocking on 27 April 2012. Soyuz TMA-22 successfully landed in Kazakhstan on 27 April 2012 11:45 GMT.
Expedition 30 was the 30th long-duration mission to the International Space Station (ISS). The expedition's first three crew members – Dan Burbank, Anton Shkaplerov and Anatoli Ivanishin – arrived on the ISS aboard Soyuz TMA-22 on 16 November 2011, during the last phase of Expedition 29. Expedition 30 formally began on 21 November 2011, with the departure from the ISS of the Soyuz TMA-02M spacecraft. The expedition ended on 27 April 2012, as Burbank, Shkaplerov and Ivanishin departed from the ISS aboard Soyuz TMA-22, marking the beginning of Expedition 31.
Expedition 50 was the 50th expedition to the International Space Station.
