Abstract : Three 4,500,000 cu ft MER J II balloons were fabricated and flown during this program. The balloons were produced from very light weight, composite and plain balloon films, the tops of the balloons were made from MERFAB reinforced composite film, while the bottom skirt employed .00032 inch thick plain MER Film. LOADWEB seam construction was used to provide adequate strength in supporting a 500 lb payload. The balloons were capable of a theoretical performance of lofting a 150 lb payload to an altitude of 150,000 ft or a 500 lb payload to 137,000 ft. The first balloon reached an altitude of 72,000 ft, the second unit was lost in a launch accident; and the third balloon was ascending at 150 fpm at 86,000 ft when it was intentionally terminated. An analysis of problems and suggested solutions are made. (Author)
