The Science and Goal
oso The objectives of the OSO satellite series were to perform solar physics experiments above the atmosphere during a complete solar cycle and to map the entire celestial sphere for direction and intensity of UV, X-ray and gamma radiation. The OSO 5 platform consisted of a sail section that pointed two experiments continually toward the sun and a wheel section that spun about an axis perpendicular to the pointing direction of the sail and carried six experiments. Attitude adjustments were performed by gas jets and a magnetic torquing coil. Pointing control permitted the pointed experiments to scan the region of the solar disk in a 40- by 40-arc-min raster pattern. In addition, the pointed section could be commanded to select and scan a 7.5- by 7-arc-min region near the solar disk. Data were simultaneously recorded on tape and transmitted by PCM/PM telemetry. A command system provided for 155 ground-based commands. For more information, see A. W. L. Ball, Spaceflight, v. 12, p. 244, 1970.
