The modular orbiting research station known as the International Space Station cost approximately $150 billion to complete. That figure may seem staggering, but keep in mind that many countries split the tab. The nations responsible for putting together the ISS were the US, Russia, Canada, Japan, Belgium, Denmark, France, Germany, Italy, the Netherlands, Norway, Spain, Sweden, and Switzerland.Ever wonder what is going to eventually happen to the ISS? The plan right now is that it will be crashed into the ocean, in the year 2020. That will be after 26 years of service.
