This is a list of all of the visitors to the International Space Station (ISS), including long-term crew, short-term visitors, and space tourists, in alphabetical order. ISS crew names are in bold. The suffix (twice, three times, ...) refers to the individual's number of spaceflights to the ISS, not the total number of spaceflights. Entries without a flag symbol indicate that the individual was an American citizen at launch. Entries without a female symbol ( 
) are men.
As of September 12,2021 [update] , 244 individuals [1] have made 403 spaceflights to the ISS, including the seven people currently at the ISS (Expedition 65). Two people have made five spaceflights to the ISS, while five people have made four, 36 people made three and 84 people made two. Note that this list assigns individuals with dual citizenship to their country of primary residence at time of launch (for example, the Iranian-American space tourist Anousheh Ansari is only listed under the United States).
Initially all private space travel was aboard the Russian Soyuz spacecraft. When only two crew members are required in the three-seat Soyuz, and additional cargo is not sent, the additional seat is sold to the general public through Space Adventures. Private travelers would remain on the ISS during handover from one expedition crew to the next, generally a week or two. The NASA Space Shuttle carried seven crew members, and the longest docking with the ISS was 11 days. Many visitors to the ISS were accommodated for short periods during NASA shuttle dockings.
NASA stated it was "not interested" in private spaceflight during construction of the ISS, but eventually began allowing up to two flights per year in 2019, with the first private visitors arriving at the US Orbital Segment in 2022 on a SpaceX Crew Dragon. [2] [3] [4]

His first spaceflight was as a mission specialist aboard STS-114 on 26 July 2005 for NASA's first "return to flight" Space Shuttle mission after the Columbia disaster. He was also in space as part of the Soyuz TMA-17 crew and Expedition 22 to the International Space Station (ISS), returning to Earth on 2 June 2010. He is the sixth Japanese astronaut to fly in space, the fifth to fly on the Space Shuttle, and the first to fly on Crew Dragon.
Soyuz TMA-7 was a transport mission for portions of the International Space Station (ISS) Expedition 12 crew launched October 1, 2005. The flight delivered ISS Commander William McArthur and ISS Flight Engineer Valery Tokarev to the station to replace Expedition 11 crew members. Spaceflight Participant Gregory Olsen joined the TMA-7 crew for the ascent and docking with the ISS, spent approximately eight days aboard conducting experiments, then returned to Earth with the outgoing members of Expedition 11 aboard Soyuz TMA-6. McArthur and Tokarev were joined on their return trip to Earth by Flight Engineer Marcos Pontes who launched aboard Soyuz TMA-8 and spent approximately seven days aboard the ISS conducting experiments for the Brazilian Space Agency.
Expedition 14 was the 14th expedition to the International Space Station (ISS). Commander Michael López-Alegría, and flight engineer Mikhail Tyurin launched from Baikonur Cosmodrome on 18 September 2006, 04:09 UTC, aboard Soyuz TMA-9. They joined Thomas Reiter, who had arrived at the ISS on 6 July 2006 aboard Space Shuttle Discovery during mission STS-121. In December 2006, Discovery mission STS-116 brought Sunita Williams to replace Reiter as the third member of Expedition 14. On 21 April 2007, López-Alegría and Tyurin returned to Earth aboard TMA-9. Landing occurred at 12:31:30 UTC.
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.

Specializing in aerospace medicine, he served as a flight surgeon for NASA before his selection as an astronaut and has played a role in developing NASA's space medicine programs for both the Shuttle-Mir Program and International Space Station. His first spaceflight was a long-duration mission to the International Space Station, as a flight engineer in the Expedition 19 and 20 crew. In March 2011, Barratt completed his second spaceflight as a crew member of STS-133. Barratt pilots the SpaceX Crew-8 mission that launched on 4 March 2024.
Expedition 16 was the 16th expedition to the International Space Station (ISS). The first two crew members, Yuri Malenchenko and Peggy Whitson, launched on 10 October 2007, aboard Soyuz TMA-11, and were joined by spaceflight participant Sheikh Muszaphar Shukor, the first Malaysian in space.
The Soyuz TMA-14 was a Soyuz flight to the International Space Station, which launched on 26 March 2009. It transported two members of the Expedition 19 crew as well as spaceflight participant Charles Simonyi on his second self-funded flight to the space station. TMA-14 was the 101st crewed flight of a Soyuz spacecraft, including launch failures; however, it was the 100th to launch and land crewed, as Soyuz 34 was launched uncrewed to replace Soyuz 32, which landed empty.
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.
Andrey Ivanovich Borisenko is a Russian cosmonaut. He was selected as a cosmonaut in May 2003, and is a veteran of two long duration missions to the International Space Station.
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.
While Russia allowed private astronaut endeavours to visit the 23-year-old station as far back as 2001, NASA resisted the practice - until announcing a change in policy in 2019 designed to boost commercial opportunities.
