The International Space station
Just A Little Introduction...
The ISS was launched on November 20th, 1998. It is located in the earth's orbit, about 240 miles away from the earth's surface. The ISS is the biggest space station built by humans, it is about the size of a football field and continues to be assembled in orbit. The station has been visited by many astronauts from 14 different countries such as; Canada, Japan, the Russian Federation, the United States, and eleven Member States of the European Space Agency (Belgium, Denmark, France, Germany, Italy, The Netherlands, Norway, Spain, Sweden, Switzerland and the United Kingdom).
Life In Space
Living in Space
If you were to live on the ISS, you would experience 15 dawns every 24 hours. Just imagine how hard it would be to find a regular sleeping pattern! Luckily, astronauts have an alarm to tell them when to go to bed and when to wake up, so they will be able to work regularly.
Since there is no gravity in space, astronauts have to be hooked onto a bed when they sleep and strapped onto a toilet when they go to the washroom. In the space station there are no showers and so you would have to clean yourself with wet towels.
In the space station, food must be somewhat confined, because if food just starts floating around the space station, not only will be unhygienic, but it will also be very dangerous, because if food gets inside the station equipment, the equipment could jam and the space station could come plummeting down to earth or, something could go seriously wrong with a science experiment.
An extremely important part of an astronaut’s daily routine is to exercise. Aside from keeping fit and on top of their game, the main reason astronauts work out during a trip in outer space, is because they suffer from a condition similar to osteoporosis. A disease that results in a significant amount of bone loss. Researchers have found that after spending weeks or months in a weightless environment, astronauts lose a significant amount of bone mineral density (BMD). The loss of BMD in the spine, neck and pelvis is about 1.0 to 1.6 percent per month, which is extremely dangerous, because by the time they go back to earth, they won’t be able to do most things, because their bones in those particular spots (and potentially more areas) would be too weak for any physical activity.
Some Cool Canadian Inventions
Canada has been very helpful to space because of our expertise in mechanics/robotics. We have made many inventions such as: The Canadarm, Dexter, the Hubble telescope, and RADARSAT. These inventions have been extremely invaluable to space because of the fact that they helped build, find and discover amazing things in space!
The Canadarm was a remote-controlled mechanical arm, also known as the Shuttle Remote Manipulator System (SRMS). During its 30-year career with NASA’s Space Shuttle Program, the robotic arm deployed, captured and repaired satellite, positioned astronauts to fix satellite and space stations, maintained equipment, and moved cargo. The Canadarm retired in July 2011 (following the Space Shuttle Program’s final mission).
Dextre (the robotic handyman)
Dextre is a robot with a job: keep the International Space Station safe and in good order. Dextre's role is to perform maintenance work and repairs such as changing batteries and replacing cameras outside the ISS. Having Dextre on call will reduce the amount of risky spacewalks to do, thus, giving astronauts more time for science, the main goal of the ISS. Dextre's special skills and awesome location also offer a unique and convenient testing ground for new robotics concepts like servicing satellites in space.
The Hubble Telescope
Hubble, the observatory, is the first major optical telescope to be placed in space. Above the distortion of the atmosphere, far far above rain clouds and light pollution, Hubble has an free view of the universe. Scientists have used Hubble to observe the most distant stars and galaxies as well as the planets in our solar system. Hubble's launch and deployment in April 1990, marked the most significant advance in astronomy since Galileo's telescope. Our view of the universe and our place within it has never been the same.
Launched in November 1995, RADARSAT-1 provided Canada and the world with an operational radar satellite system capable of timely delivery of large amounts of data. Equipped with a powerful synthetic aperture radar (SAR) instrument, it acquired images of the Earth day or night, in all weather and through cloud cover, smoke and haze.
