What it is

A Canadian satellite carrying a topside ionospheric sounder that mapped the layer from above. It made Canada the third country to design and build a satellite, although the United States launched it.

Launched from Vandenberg (California) on a Thor-Agena rocket. The builder's laboratory was at Shirleys Bay, Ottawa.

What it led to

  • the ISIS programme and Canadian science satellites
  • systematic study of the ionosphere and shortwave communications
  • Canada's space industry (later the Canadarm)
