The International Space Station (ISS) is a manned, artificial satellite being constructed in low Earth orbit. The ISS is an international effort with 5 partners, whose current objectives vary, (space agencies in alphabetical order)*CSA. Canada concentrates on Robotics and Science.*ESA. Europe conducts Scientific Research and develops Spaceship Navigation, Propulsion and Docking.*JAXA. Japan concentrates on Research in Material and Life sciences, also Liberal Arts and Education with the largest Laboratory in 6 elements spanning 3 segments.*NASA. the United States provides the Space Shuttle for logistic support, conducts Scientific research, and develops life support systems in accordace with current policy.*RKA. Russia continues it's development of Spacecraft, space stations and all associated systems, as well as Science and exploration.
The International Space Station (ISS) is an internationally developed research facility that is being assembled in low Earth orbit. On-orbit construction of the station began in 1998 and is scheduled for completion by late 2011. The station is expected to remain in operation until at least 2015, and likely 2020.With a greater cross-sectional area than that of any previous space station, the ISS can be seen from Earth with the naked eye, and is by far the largest artificial satellite that has ever orbited Earth. The ISS serves as a research laboratory that has a microgravity environment in which crews conduct experiments in biology, chemistry, medicine, physiology and physics, as well as astronomical and meteorological observations. The station provides a unique environment for the testing of the spacecraft systems that will be required for missions to the Moon and Mars. The ISS is operated by Expedition crews of six astronauts and cosmonauts, with the station programme maintaining an uninterrupted human presence in space since the launch of Expedition 1 on 31 October 2000, a total of , the crew of Expedition 26 is aboard.
