How does International space station work

 HOW DOES INTERNATIONAL SPACE STATION WORK.

The International Space Station (ISS) is a modular space station (habitable artificial satellite) in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars.

The ISS maintains an orbit with an altitude of between 330 and 435 km (205 and 270 mi) by means of reboost maneuvers using the engines of the Zvezda module or visiting spacecraft. It circles the Earth in roughly 93 minutes, completing 15.5 orbits per day. The ISS is the ninth space station to be inhabited by crews, following the Soviet and later Russian Salyut, Almaz, and Mir stations as well as Skylab from the US. The station has been continuously occupied for more than 22 years, having surpassed the previous record of almost 10 years (3,643 days) held by Mir.

The ISS is the largest human-made body in low Earth orbit and can often be seen with the naked eye from Earth. The ISS consists of pressurized modules, external trusses, solar arrays, and other components. ISS components have been launched by Russian Proton and Soyuz rockets, and American Space Shuttles.

The ISS is operated by the partnership of NASA, Roscosmos, JAXA, ESA, and CSA. The ownership and use of the space station is established by intergovernmental treaties and agreements. The station is divided into two sections, the Russian Orbital Segment (ROS) and the United States Orbital Segment (USOS), which is shared by many nations. As of January 2021, the American portion of ISS is being funded until 2024. Roscosmos has endorsed the continued operation of ISS through 2028, but has proposed using elements of the Russian Orbital Segment to construct a new Russian space station called OPSEK.

The ISS provides a platform to conduct scientific research, the results of which contribute to an understanding of the Earth and the universe as well as solving problems related to space flight. ISS research has focused on astrobiology, astronomy, human biology, meteorology, physics, and many other fields. The ISS is equipped with a wide variety of scientific instruments and experiments that enable researchers to study the effects of long-term space flight on the human body as well as the Earth and its atmosphere.

The ISS has a crew of six, with space for eight crew members in total. The space station is serviced by a variety of visiting spacecraft: the Russian Soyuz and Progress, the American Dragon and Cygnus, and the Japanese H-II Transfer Vehicle. It has also been visited by space tourists, the first being Dennis Tito of the United States in 2001.

The ISS has been continuously occupied since November 2000. The current crew, Expedition 65, arrived on April 23, 2021 and consists of three American astronauts, two Russian cosmonauts, and one Japanese astronaut. The station is serviced by a variety of spacecraft, including the Soyuz and Progress vehicles, as well as commercial spacecraft such as the Dragon and Cygnus.

The ISS is a modular structure, consisting of pressurized habitation modules, structural trusses, solar arrays, and other components. The station is powered by photovoltaic panels and batteries. The ISS has a mass of approximately 420,000 kg
