High-Energy Astronomy Observatory 1 (HEAO 1) was the first in a series of three satellite observatories designed to continue the X-ray and gamma-ray studies initiated by ANS, OAO 3, UK 5, the OSO series, the SAS series, and the gamma-ray burst discoveries of the Vela satellites. This mission was specifically designed to map and survey the celestial sphere for X-ray and gamma-ray sources in the energy range of 150 eV to 10 MeV, to establish the size and precise location of X-ray sources to determine the contribution of discrete sources to the X-ray background, and to measure time variations of X-ray sources.
