Title: International Space Station
Content:   The assembly of the International Space Station, a major endeavour in space architecture, began in November 1998. Russian modules launched and docked robotically, with the exception of Rassvet. All other modules were delivered by the Space Shuttle, which required installation by ISS and Shuttle crewmembers using the Canadarm2 (SSRMS) and extra-vehicular activities (EVAs); by 5 June 2011, they had added 159 components during more than 1,000 hours of EVA. 127 of these spacewalks originated from the station, and the remaining 32 were launched from the airlocks of docked Space Shuttles. The beta angle of the station had to be considered at all times during construction. The first 
Title: Space exploration
Content:  Salyut 1 was the first space station of any kind, launched into low Earth orbit by the Soviet Union on 19 April 1971. The International Space Station is currently the only fully functional space station, inhabited continuously since the year 2000.
Title: Human spaceflight
Content:   The dissolution of the Soviet Union in 1991 brought an end to the Cold War and opened the door to true cooperation between the US and Russia. The Soviet Soyuz and Mir programs were taken over by the Russian Federal Space Agency, now known as the Roscosmos State Corporation. The Shuttle-Mir Program included American Space Shuttles visiting the Mir space station, Russian cosmonauts flying on the Shuttle, and an American astronaut flying aboard a Soyuz spacecraft for long-duration expeditions aboard Mir. In 1993, President Bill Clinton secured Russia's cooperation in converting the planned Space Station Freedom into the International Space Station (ISS). Construction of the station began in 1998. The station orbits at an altitude of 409 km and an orbital inclination of 51.65°. Several of the Space Shuttle's 135 orbital flights were to help assemble, supply, and crew the ISS. Russia has built half of the International Space Station and has continued its cooperation with the US.
Title: Expedition 1
Content:  Expedition 1 was the first long-duration stay on the International Space Station (ISS). The three-person crew stayed aboard the station for 136 days, from November 2000 to March 2001. It was the beginning of an uninterrupted human presence on the station which continues as of June 2022. Expedition 2, which also had three crew members, immediately followed Expedition 1. The official start of the expedition occurred when the crew docked to the station on 2 November 2000, aboard the Russian spacecraft Soyuz TM-31, which had launched on 31 October 2000 at the Baikonur Cosmodrome in Kazakhstan. During their mission, the Expedition 1 crew activated various systems on 
Title: List of International Space Station spacewalks
Content:  December 1998, following the launch of the first section of the station, Zarya, from Baikonur Cosmodrome, Kazakhstan, on 20 November 1998. The spacewalk attached the U.S.-built Unity node to Zarya. The longest spacewalk was performed on 11 March 2001, when STS-102 crew members Susan J. Helms and James S. Voss conducted a full spacewalk, and then returned to the airlock, but remained in their suits ready to exit the airlock again in case the robotics operations ran into problems. The total time for that spacewalk was eight hours and fifty-six minutes. As of 2 December 2021, there have been 245 spacewalks devoted to assembly and maintenance of the International Space Station totaling 1548 hours 
Title: Space Station Freedom
Content:   In 1993, the Clinton administration announced the transformation of Space Station Freedom into the International Space Station (ISS). NASA Administrator Daniel Goldin supervised the addition of Russia to the project. To accommodate reduced budgets, the station design was scaled back from 508 to 353 square feet (47 to 33 m²), the crew capacity of the NASA-provided part was reduced from 7 to 3 (while the complete station is crewed by 6 but may be increased to 7 ), and the station's functions were reduced. Its first component was launched into orbit in 1998, with the first long-term residents arriving in November 2000.
Title: International Space Station
Content:  from the Baikonur Cosmodrome on 31 October 2000. The station has since been continuously occupied for, the longest continuous human presence in low Earth orbit, having surpassed the previous record of 20 years, 357 days held by the Mir space station. The latest major pressurised module, Nauka, was fitted in 2021, a little over ten years after the previous major addition, Leonardo in 2011. Development and assembly of the station continues, with an experimental inflatable space habitat added in 2016, and several major new Russian elements scheduled for launch starting in 2021. In December 2018, the station's operation authorization was extended to 2030, 
Title: International Space Station
Content:  Pirs (Russian: Пирс, lit. 'Pier') was launched on 14 September 2001, as ISS Assembly Mission 4R, on a Russian Soyuz-U rocket, using a modified Progress spacecraft, Progress M-SO1, as an upper stage. Pirs was undocked by Progress MS-16 on 26 July 2021, 10:56 UTC, and deorbited on the same day at 14:51 UTC to make room for Nauka module to be attached to the space station. Prior to its departure, Pirs served as the primary Russian airlock on the station, being used to store and refurbish the Russian Orlan spacesuits.
Title: Space research
Content:   The International Space Station received its first crew as part of STS-88, in December 1998, an internationally co-operative mission of almost 20 participants. The station has been continuously occupied for, exceeding the previous record, almost ten years by Russian station Mir. The ISS provides research in microgravity, and exposure to the local space environment. Crew members conduct tests relevant to biology, physics, astronomy, and others. Even studying the experience and health of the crew advances space research.
Title: Origins of the International Space Station
Content:  Origins of the International Space Station covers the origins of ISS. The International Space Station programme represents a combination of three national space station projects: the Russian/Soviet Mir-2, NASA's Space Station Freedom including the Japanese Kibō laboratory, and the European Columbus space stations. Canadian robotics supplement these projects. In the early 1980s, NASA planned to launch a modular space station called Freedom as a counterpart to the Soviet Salyut and Mir space stations. In 1984 the ESA was invited to participate in Space Station Freedom, and the ESA approved the Columbus laboratory by 1987. The Japanese Experiment Module (JEM), or Kibō, was announced in 1985, as part of the Freedom space station in response to a NASA request in 1982. In early 1985, science ministers from the European Space Agency (ESA) countries approved the
