Canada's stratospheric balloon program was scaled back about a decade ago for budgetary reasons. Recently, France had to seek out new mid-latitude site for balloon launches and recovery because of Europe's heavy population density. Thus, in 2011, through a Franco-Canadian collaboration, the Canadian Space Agency's (CSA) Balloon Program known as Stratos was created.
Preparation of a balloon launch
