International Space Station
In the early 1980's, the International Space Station (ISS) was only an idea on paper. Today, the ISS is a result of sixteen international partners working together to create a world-class, state-of-the-art orbiting research facility.
The ISS provides scientists, engineers and entrepreneurs an opportunity to perform complex experiments over long periods of time in a space environment. But, it is much more; it is an international "city in space" - a place where we will learn how to live and work "off planet."
Some facts about the International Space Station
- The Space Station is the largest manned object ever sent into space - larger than the new Airbus 380 recently put into service to carry over 500 passengers. It consists of 70 separate major components and hundreds of minor ones. All the parts will be put together in space for the first time.
- This is a BIG construction job - 45 launches in total to assemble the parts and over 1700 hours of space walks for the astronauts and cosmonauts. Future plans for missions to the ISS can be found at http://www.nasa.gov/mission_pages/station/structure/iss_manifest.html
- We can see it - and the people on board can see us! When completed, the ISS will be visible to more than 90 percent of the world's population and circles the Earth every 90 minutes.
- Canadian astronaut, Dr. Robert Thirsk, spent 187 days on board the ISS in 2009.
- In November 2012, Canadian Astronaut Chris Hadfield joined the crew on the International Space Station (Expedition 34/35); his journey up to and returning from the ISS was on a Russian Soyuz vehicle.
- During the second half of his mission Hadfield became the first Canadian Commander of the ISS–a milestone for Canadian space exploration. In addition to overseeing operations as Commander, he carried out scientific experiments, operated Canadarm2 and performed various robotics tasks.
- Having trouble sleeping? Humans need less sleep in space because the body does little work in a microgravity environment. It takes little effort to raise an arm, hold your head up, or move a bulky object.
- It's a team effort - many countries are involved - the United States, Russia, Canada, Japan, Belgium, Brazil, Denmark, France, Germany, Italy, the Netherlands, Norway, Spain, Sweden, Switzerland and the United Kingdom. The construction involves more than 100,000 people, and hundreds of companies. Astronauts also work in teams on the various experiments aboard the ISS.
- Keep working in Physical Education classes - Every astronaut must do at least two hours of strenuous exercise, every day. This is to counteract the tendency of the human body to lose muscle and bone mass rapidly in space.
- It's not cheap! It is the most expensive object every built. The Chunnel between England and France cost about $22 billion. The United States' contribution ALONE is estimated at nearly $200 billion!
