The Air Force Cambridge Research Laboratories Superpressure Balloon assumes this spherical shape at floating altitudes. This 34-foot diameter Mylar film balloon whose materials is 1 and 1/2 mils (thousandths of an inch) thick does not require ballast to maintain altitude. A recent record 10-day flight saw the superpressure balloon remain at altitudes of 68,500 feet. Flight information was obtained using a lightweight balloon borne high frequency transmitter in combination with specially designed balloon borne sensing elements. Parameters measured included balloon gas and free air temperature together with the air and balloon gas pressures. These data, and knowledge of balloon volume constancy and spectral absorption characteristics of the film, permit a complete analysis of balloon performance.Photo measures 9.75 x 8inches.
