History of International Space Station

The International Space Station was originally conceived as our base camp to the stars and the first step in a long journey of human civilization exploring new planets, asteroids, and galaxies, and perhaps even helping us to meet other forms of life in the universe along the way.

What Is the International Space Station?

The International Space Station (ISS) is a massive space station (like habitable artificial satellite) in the low Earth orbit. The ISS programme is a joint project between five space agencies around the world: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and utilization of the space station are established through intergovernmental treaties and agreements.

The International Space Station is a huge spacecraft and It orbits around our globe. It is not only the home to astronauts. But, the space station is also a science lab. Many countries have worked together to build it.so, they work together to use it.

Many pieces and segments make up the ISS. Astronauts had put these pieces together. The space station’s orbit is approx 250 miles above the Earth. The ISS also serves as a microgravity and space environment research laboratory in which crew members conduct various types of experiments.Image result for what is iss

How Old Is the Space Station?

In 1998 a Russian rocket launched the first piece into space.Within two years the space station was ready for people. The first crew arrived on November 2, 2000. Since then, the station has been continuously occupied by humans for 18 years and 271 days. This is the longest  period of human presence in low Earth orbit . NASA and its partners around the world finished the space station works in 2011.

Manufacturing and Assembly

Various countries around the world manufactured the different components for in-orbit assembly. Because the International Space Station is a multi-national collaborative project.

The Marshall Space Flight Center and the Michoud Assembly Facility fabricated the U.S. components Destiny and Unity.

The Khrunichev State Research and Production Space Center in Moscow manufactured the Russian modules, including Zarya and Zvezda.

The European Space Research and Technology Centre (ESTEC) in the Netherlands manufactured the European Space Agency Columbus module.

The NASDA (now JAXA) Tanegashima Space Center and the Institute of Space and Astronautical Science fabricated the Japanese Experiment Module Kibo.

Various factories in Canada and the United States under contract by the Canadian Space Agency manufactured The Mobile Servicing System, consisting of the Canadaarm-2 and the Dextre.

The assembly of the International Space Station, a major endeavour in space architecture. It began in November 1998. The Russian modules were launched and docked by robots, with the exception of the Rassvet. Then, Space shuttles delivered other modules, which required the installation by ISS and shuttle crew members using the Canadarm2 (SSRMS) and extra-vehicular activities (EVAs). As of 5 June 2011, they had added 159 components during more than 1,000 hours of EVA.

The gross mass of the station changes over time. The total launch mass of all modules on the orbit is about 417,289 kg (919,965 lb) (as of 3 September 2011).
