The International Space Station is a habitable artificial satellite in low Earth orbit. It follows the Salyut, Almaz, Skylab and Mir stations as the ninth space station to be inhabited. The station has been continuously occupied for 12 years and 163 days, having exceeded the previous record of almost 10 years (or 3,634 days) held by Mir, in 2010. The station is serviced by Soyuzspacecraft, Progress spacecraft, the Automated Transfer Vehicle, the H-II Transfer Vehicle,and the Dragon spacecraft. It has been visited by astronauts and cosmonauts from 15 different nations.
The ISS serves as a micro gravity and space envirnonment 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. (Wikipedia)
