The International Space Station (ISS)

The International Space Station (ISS) is a result of the collaboration between six countries (United States, Russia, Japan, Canada, Italy, and Brazil) and the European Space Agency.

Not only has it been inhabited by astronauts continuously since the first crew entered the station on November 2nd 2000 but amazingly it only needs three astronauts on board at any point in time, thats pretty efficient for a high tech space station don’t you think ?
Overall it has four modules, the Zvezda Module which is where the crew sleep, exercise, and eat. The Zarya Module which houses the controls for navigation, communication, propulsion, and electric power.

The Unity Module which is called the “Node,” as it forms a connecting passageway allowing astronauts to depressurize when they leave the station. Finally the Destiny Module which is the laboratory where sophisticated instruments are found and used for experiments.
