The HEAO (High Energy Astronomy Observatory) Program consists of three large automated scientific observatories launched between 1977 and 1979 to observe from near-earth orbit stellar X-ray and gamma-ray sources and to measure incoming cosmic ray particles. The HEAO-2 and HEAO-3 spacecraft are expected to exceed their design lifetimes by a factor of three, as did HEAO-1, which operated for 18 months. All three missions are considered successful in that target dates have essentially been met, launch and flight operations have been relatively smooth, instrumentation has performed well, and there have been no cost overruns. The paper lists ten factors contributing to the missions' success, among them a thorough definition before program start, commonality of spacecraft design, redundancy of mission critical equipment, ample design margins, and tight control of system changes. Specific mission parameters are included in the paper as well as the technological advances engendered by the HEAO Program in such areas as high-resolution X-ray optics and solid-state spectrometry.
