Stratospheric balloons

Did you know? Fact number 1

The volume of the largest open stratospheric balloons used by Centre National d'Etudes Spatiales (CNES) can be up to 1,200,000 m3.

Did you know? Fact number 2

The height of a deployed balloon, including the flight chain, is about 300 m, about half as tall as the CN Tower.

Did you know? Fact number 3

The envelope alone can be as high as a 35-floor building, or the height of the tower of Montreal's Olympic Stadium; and its diameter is equivalent to the size of 2 hockey rinks or 2 Airbus A-340s.

Did you know? Fact number 4

The area of the envelope, if deployed flat, is equivalent to approximately 8 soccer fields.

Stratos, the Canadian Space Agency's (CSA) stratospheric balloon program, was created in 2011 through the CSA's collaboration with the Centre National d'Études Spatiales (CNES). This program gives Canadian academia and industry the opportunity to test and validate new technologies and to perform scientific experiments at an altitude where only balloons can be operated. Stratos therefore contributes to the training and development of a highly qualified workforce: the next generation of Canadian engineers and scientists.

Campaigns Coming Up

The Canadian space industry and academia will be part of two stratospheric balloon launch campaigns taking place in 2016 and 2017.

The KASA 2016 campaign (August 20 - September 10, 2016) will be held from the Esrange Space Center based in Kiruna, Sweden, while the 2017 campaign will take place in Alice Springs, Australia.
