11.3 The Exploration of Space and Technologies used for Space Exploration Human understanding of Earth and its place in the universe has evolved as technology has enabled us to see farther into space.

What is the Canadian Space Agency The Canadian agency that heads up space research for Canada. Canada’s involvement is relatively new compared to the USA and Russia

ISS - Launched in 1998 and involves: USA Russia Canada Japan Countries of the European Space Agency ISS

What is Canada’s contribution to space research?? Canadarm 1  Canadian designed and built robotic arm  Used to retrieve and launch satellites  Provide a platform for astronauts to complete their tasks in space

Canadian contributions …. Building and Designing  Helped build the International Space Station which is a space based laboratory the orbits the Earth  Its lifetime expected to be about 30 years

Canadian contributions…. Canadarm 2  A mobile remote manipulator system designed for the International Space Station  Larger than Canadarm 1 and able to move by itself Compare Canadarm and Canadarm2

Canadian contributions…… Special Purpose Dexterous Manipulator  Launched in 2008  Dual-armed robot  A device that allows astronauts to perform tasks without leaving their spacecraft Dextre

Who are the Canadian Astronauts? 1.Roberta Bondar  Had childhood dream to be an astronaut  Launched from Earth aboard NASA space shuttle Discovery  Canada’s first female astronaut

Canadian astronauts…. 2.Marc Garneau  First Canadian in space  Taken 3 flights aboard NASA space shuttle  President of Canadian Space Agency from 2001 to 2006

Canadian Astronauts… 3.Chris Hadfield  First Canadian to walk in space  NASA's Chief voice of mission control to astronauts in orbit, for 25 space shuttle missions  Onboard a NASA space shuttle which docked with a Russian shuttle in 1995

Technologies Used to Explore Space There are various scientific disciplines involved in developing technologies designed for space exploration For example: Physics – Telescope Chemistry – Food preservation, Rocket propulsion

Technologies continued…. Rocket Propulsion Burning fuel creates thrust that pushes the rocket forward

Technologies continued…. Space Suits Space Suit Acts as a spaceship, providing oxygen to breath, a communication system, a cooling system, and maintains air pressure similar to that on Earth

Technologies continued…. Orbiting Satellites

Technologies continued…. Probes Sputnik 1 was first to go in space launched in 1957 Carry scientific instruments such as telescopes Analyze distant objects in space Land on the surface of the object and send information back to Earth More sophisticated probes are called rovers

Technologies continued…. Rovers Mars Rover Mars Exploration Rovers Movable probes designed to land on a planet Explore the surface and send information back to earth SEV (surface exploration vehicle) with wheels that can pivot 360

Technologies continued…. Optical telescope - Uses a series of mirrors to collect and project the image to an eyepiece for the view. Canada-France-Hawaii “Reflecting Telescope”

Technologies continued…. Optical telescope Reflecting telescope that was built by NASA. Carried into orbit in Hubble Space Telescope

Technologies continued…. Radio Telescopes Collects wavelengths that are longer than those of light. Radio signals are collected and focused on a large receiver. Reveal characteristics of celestial bodies that could not be studied using optical telescopes.

Technologies continued…. Radio TelescopeTelescopes Very Large Array Facility
