The space shuttle orbits at 200km, that would be the distance from Fredericton to Grand Falls.BLM 16.1 Vehicles in and Above Earths Surface
Satellites (16.3)What are they?They are objects that revolve around the Earth. There are natural and man-made satellites.Natural: MoonMan-Made: TV, weather, cell-phone, communication, scientific, Radar, Infrared, military, space stationsMost are low Earth orbit satellites (200km high)
Satellites generally travel with the Earth at 28 000 km/h and take about 1.5 hours to circle Earth.
Some are geosynchronous, travel at the same speed as the Earth so they stay in one spot. (telecommunications)
Some are slower, usually specialty satellites like the International Space Station and Hubble Space Telescope.
RADARSAT (16.4)Read p. 496It is a low orbit Radar Satellite hence the name.A radar is a device that emits bursts of radio waves and picks up the reflections to find out how far they are. (RAdio Detecting And Ranging)
How long and it bounces determines what it is detecting.Radio waves travel at the speed of light and can penetrate clouds.It is good for monitoring mining and disasters.Canadians built and operate it!
Other Canadian ContributionsAlovethe 1: a scientific research satellite that made Canada the 3rd country into space. (1962)Anik 1: a communication satellite in geosynchronous orbit for communications. (1972)Canada is the world leader in communications.the history blips on TV with the towers.First trans-Atlantic message.First communication satellite.First cell phone service.
Canada is also a world leader in Robotics.
Marc Garneau was the first Canadian in space. He is now the head of the Canadian Space Agency (CSA).
What is Canadas most famous space equipment?Canada Arm
International Space Station (ISS)(16.6)The first living quarters in space were Salyut then Skylab.
Mir was the first continuously docked lab.
Now International Space Station includes:Brazil Canada EuropeJapanRussiaUSA
Four Research Modules (ISS)Service ModuleHabitation ModuleRemote Robotic controlsCargo BlockDocking stationHuge solar panels
These parts are all connected to a central beam 100m long.It took 45 launches of satellites, revolves at 450 km, and weighs 450 000 kg.
