The International Space Station is a modular space station in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA, Roscosmos, JAXA, ESA, and CSA. The ownership and use of the space station is established by intergovernmental treaties and agreements. The gravitational field on the ISS is approximately 89% of that on the Earth's surface. Of course, irrespective of these facts, the astronauts on board the ISS (and even the ISS itself) feel 'weightless' .The International Space Station is a large spacecraft in orbit around Earth. It serves as a home where crews of astronauts and cosmonauts live. The space station is also a unique science laboratory. Over its 20+ years in orbit, the international space station costs over $150 billion to develop, making it the most expensive thing ever built. The ISS is not owned by one single nation and is a “co-operative programme” between Europe, the United States, Russia, Canada and Japan, according to the European Space Agency (ESA). As of April 2021, 244 individuals from 19 countries have visited the International Space Station. When fully complete, the ISS will weigh about 420,000 kilograms (925,000 pounds). This is equivalent to more than 330 automobiles. It will measure 74 meters (243 feet) long by 110 meters (361 feet) wide. This is equivalent to a football field, including the end zones. the dimensions of the International Space Station (ISS) will be approximately 108.5 meters by 72.8 meters. This is slightly larger then a full sized soccer field. The completed ISS will weigh around 450 tons. The ISS travels at about 17,500 miles/28,000 kilometers per hour. At this speed, the ISS orbits the Earth every 90 minutes, which gives the crew 16 sunrises and sunsets every day. Nasa has announced plans for the International Space Station (ISS) to be officially decommissioned in 2031. After dozens of launches since 1998 got the station up and into orbit, bringing it down will be a feat of its own.
