Alouette/Aurora satellites

Alouette and Aurora are Canadian satellites launched in the 1960s and 1970s to study Earth's ionosphere—a layer of charged particles crucial for radio communication. Alouette was the first satellite built in Canada, primarily measuring the ionosphere's properties. Aurora satellites focused on monitoring space weather phenomena like solar storms that affect communication and navigation systems. They provided valuable data helping scientists understand the Earth's space environment, aiding the development of better communication systems and satellite technology. These missions advanced Canada's role in space science and laid the groundwork for future space-based atmospheric research.
