Since 1998, orbits 400 km above Earth Largest spacecraft ever built
Canadarm2 Robotic device One of three designed and built in Canada by
a Canadian company Moves astronauts around as they work outside
the space station Can bend around corners and grasp objects
with computer-controlled fingers

Canada was the 3rd country in the world to launch a satellite Called Alouette 1 Collected data about extreme upper regions of
atmostphere Launched a bunch of satellites called Anik
Started in 1972 Anik 1 gave Canada 12 television channels first
country with a satellite in geostationary orbit!! :o Extremely important for connecting northern parts
with rest of country Anik F3 (2007) is 5900kg, provides broadcast and
broadband internet services across North America

1918 – at 1.83m, largest telescope in the world at Dominion Astrophysical Observatory in Victoria, BC Beginning of serious gvt funding in research in astronomy
1935 at U of T another big telescope Showed beginning of universities helping research
1951 – Canadian Impact Crater Program Impacts have a profound impact to life on Earth
1960 – discovery by Canadians of complex molecules in space
1985 – Canadian Institute for Theoretical Astrophysics opened world leader in understanding planetary systems, stars and life cycles, origin and evolution of universe

Sudbury Neutrino Observatory World’s more powerful detector of neutrinos
(particles emitted by nuclear reactions in stars and supernovas)
Solved the solar neutrino problem 2000 Canadian scientists recovered a
meteorite in BC from a lake Most primitive meteorite EVER!! About 4.5 billion years old – how old we expect
our solar system to be! :o
