The International Space Station serves as a floating science laboratory, deep space observatory and high tech Earth observation station. With 15 partner nations and five space agencies, the ISS is the largest international peacetime project in history. The first module, Zarya (Dawn), was launched by the Russians in November of 1998. The last construction flight was the delivery of the alpha magnetic spectrometer onboard the Space Shuttle Endeavour, mission STS-134. The station consists of 16 pressurized modules, the integrated truss structure and the solar arrays. The ISS expected lifetime ends in 2031.
