The International Space Station was launched in 1998 and is the joint venture of countries such as the United States and Russia. The station is about the size of a five bedroom house and in Earth's gravity, would weigh around 1 million pounds. Inside the space station lies laboratories, living areas for the crew and modules designed to hold the different parts of the space station together.
Today, the International Space Station is used to explore space. When the organization can figure out how space travel affects people, it can begin to explore its reach into space.Learn more about Space Travel
