Book Statistics
Protection of materials and structures from space environment
Description
It has only been 44 years since a small Russian aluminum sphere called Sputnik orbited the Earth for three months and, in doing so, launched the Space Age. Canada's own Space Program dates back to the launch of Alouette-1, which made us the third nation in space in 1962. Incredibly, for all the accomplishments along the way, our journey as a species into space has not yet spanned a human lifetime. Canada first went into space for practical reasons. The rationale behind the launch of our debut satellite, Alouette-1, was simple: Canadian scientists wanted to understand why ionospheric activity, prevalent in the far North, adversely affected radio communications. The best way to find out was to place a spacecraft in orbit for in situ measurements. Ten years later, mission accomplished: Alouette was switched off and Canada emerged as a world expert on ionospheric phenomena.
