Definitions

  • High-altitude balloons are generally unmanned balloons, usually filled with helium or hydrogen, that are released into the stratosphere, generally attaining an altitude of about 60,000 feet (18 km) to 120,000 feet (37 km). Conditions in the stratosphere can subject the materials in the balloon to severe physical stresses at low temperatures. However, to maximize carrying capacity, lightweight high altitude balloon materials are desirable.
