The  International Space Station  (ISS) is a multi-nation construction project. It the largest single structure humans ever put into space. ISS has a pressurized volume of approximately 900 m3 (31,000 ft3) and a mass over 400,000 kg (900,000 lbs). Actual numbers vary as logistics resupply vehicles come and go on a frequent and regular basis. Its main construction completed between 1998 and 2011, although the station continually evolves to include new missions and experiments. It has been continuously occupied since Nov. 2, 2000.

The ISS includes contributions from 15 nations. NASA (United States), Roscosmos (Russia) and the European Space Agency are the major partners of the space station and contribute most of the funding. The other partners are the Japanese Aerospace Exploration Agency and the Canadian Space Agency.

The ISS solar arrays cover an area of 2,247 m2 (24,187 ft2). It can generate 735,000 kW-hours of electrical power per year.

The ISS structure measures 109 m (358 ft) (across arrays) by 51 m (168 ft).

ISS orbits at an altitude of between 370–460 km (200–250 nmi). Its falls towards Earth continually due to atmospheric friction and requires periodic rocket firings to boost the orbit. Its orbital inclination is 51.6°, permitting it to fly over 90% of the inhabited Earth.

ISS carries a crew of between 3 and 13 depending on then number of people and passenger vehicles during handover periods, It continually hosts a crew of seven.

the only Indian citizen to have traveled to space is Rakesh Sharma, who flew aboard Soyuz T-11 in 1984. Other astronauts of Indian origin who have flown in space include Kalpana Chawla, Sunita Williams, and Raja Char

Group captain Shubhanshu Shukla is the latest Indian in space. ISRO announced in 2024 that he chosen to go on an Indo-US collaborative mission to the International Space Station.
