About 70 years ago the world fell into one of the greatest wars known to man. Not so many years after that we were thrown into the cold war. Who would have believed that before the end of the 20th century, countries which were mortal enemies for most of this century would join together to create a space station? The countries currently participating are the United States, Russia, Japan, Canada, and many European countries. The Space Station has enabled us to learn that we can work together peacefully, especially in pursuit of scientific knowledge.
In the early 1980s, NASA planned the Freedom Space Station as part of the Salyut and Mir Soviet space stations. It never left the drawing board and, with the end of the Soviet Union and the Cold War, it was canceled. The end of the space race encouraged US administration officials to start negotiations with European international partners, Russia, Japan and Canada in the early 1990s to build truly international space stations. The project was first announced in 1993. The first part, the Zarya Functional Cargo Block, was placed in orbit in November 1998 with Russian Proton rockets.
ISS serves as a microgravity research laboratory and space environment where crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields. This station is suitable for testing spacecraft systems and equipment needed for missions to the Moon and Mars. Since 2000, 220 people from 17 countries have visited the ISS. The first crew consisted of three astronauts from America, Russia and Ukraine. At present six people live on the boat, and despite taking a strange break to play with floating. To date, the International Space Station has cost up to $ 160 billion, with the United States providing the bulk of that money – almost $ 100 billion (although that depends on how you include the price of the space shuttle program).
