International Space Station assembly, animation. The International Space Station (ISS) was built in stages since 1998. It is a collaborative project between the national space agencies of the USA, Canada, Japan, Russia and Europe. It consists of a number of modules, trusses and arrays of solar panels. The first three modules shown in the animation are the Zarya, Unity and Zvezda modules. This was followed by parts of the Integrated Truss Structure (ITS) and solar panels, the Canadarm robotic arm, and then by the Destiny laboratory (cylindrical) in 2001. By about halfway through the animation, the ITS is mostly completed. Further major additions were the Harmony node, the Columbus module, the Kibo module, the Poisk module, the Tranquility node, the Cupola, the Rassvet module, and the Leonardo module (2011). The ISS operates as a microgravity and space environment research laboratory, with experiments conducted by crew members. Orbiting at an altitude of around 360 kilometres, it has been crewed since 2000, and will remain operational until at least 2020. |
