The International Space Station is an Earth orbiting laboratory. The station has been in orbit since 1998 and is expected to remain in operation until at least 2020. The International Space Station is visited by ISS crew expeditions.
What is the International Space Station?
The International Space Station (ISS) is the largest space project to date and the most complex international scientific project in history. It is a joint a collaboration of 16 countries: United States (NASA), Russia (Russian Federal Space Agency – formerly Rosaviakosmos), Brazil, Canada (Canadian Space Agency), Japan Aerospace Exploration Agency (JAXA) and the European Space Agency. ESA members involved are Belgium, Denmark, France, Germany, Italy, Netherlands, Norway, Spain, Sweden, Switzerland and United Kingdom. NASA uses the station to learn about living and working in space.

Space Station Information
The ISS is visited by a variety of spacecraft use docking ports to connect to the space station. The Quest Airlock enables access for spacewalks essential to the facility’s continuing construction.
Canadarm2 is a Canadian-built apparatus is a large, remote-controlled space arm that functions as a crane and is being utilized for a wide variety of tasks.
The International Space Station travels around the Earth at an average speed of 27,700 km/hr and completes 16 orbits per day
When fully constructed, the Space Station will be visible to more than 90 percent of the world’s population. Also when finished the space station will be one of the brightest objects in the sky.
How Big Is the Space Station?
The ISS is as big inside as a house with five bedrooms and can cover a football field. It has science labs from the United States, Russia, Japan and Europe. Six live on the ISS. It weighs almost a million pounds. The ISS will be 5 times larger than Mir when complete.
How Old Is the Space Station?
The first module of the International Space Station was launched in 1998. The first crew arrived in October 2000. People have lived on the space station ever since.
ISS Expedition Crews are delivered to the ISS Russia’s Soyuz Spacecraft. Space Shuttle is no longer used because it has been retired. At present, the Soyuz functions as the only crewed space vehicle and is the ISS Emergency Crew Vehicle. Cargo is delivered by Russia’s Progress Spacecraft, Europe’s ATV, Japan’s H-II Transfer Vehicle, Orbital ATK’s Cygnus and SpaceX Dragon spacecraft. In the future Boeing CST-100 and SpaceX Dragon will deliver crew to ISS. Also Dream Chaser spaceplane in 2020 will be used carry cargo to the ISS. The US Space Shuttle is no longer used for crew and cargo delivery to the ISS. It was retired in 2011.
Manned Missions: The current mission is Expedition 49.
Space Shuttle and the ISS
Space Shuttle Endeavour STS-88 was the first Space Shuttle mission to the International Space Station (ISS). It also carried the first American module (the Unity node) to the station.
The last space shuttle to the International Space Station was Space Shuttle Atlantis STS-135. The final mission was launched on 8 July 2011.
What are the Parts of the Space Station?
The International Space Station consists of many parts called modules. These modules provide living areas. Modules called ‘nodes’ connect other parts. Labs on the space station let astronauts do research.
Solar Arrays are used to collect energy from the sun. They turn it into electricity. They are located on the sides of the space station. Robot arms are attached outside. Some helped to build the space station. They can also move astronauts around outside. Other arms control science experiments.
Airlocks on the space station are like doors. Astronauts use them to go outside on spacewalks. Astronauts work in spacesuits to help build and maintain the space station.
