In this instance, the BESS (Balloon-borne Experiment with a Superconducting Spectrometer) lifted off from Lynn Lake in Manitoba, Canada, August 7 2002

A scientific balloon being launched near Lynn Lake in Manitoba, Canada. The small amount of gas in the envelope expands to fill its 40-million-cubic-foot capacity as it climbs to reach the rarefied atmosphere at the balloon's cruise altitude of 23 miles. The 5,300-pound experiment is suspended from the launch crane whilst the balloon is being filled.
