Description of the OSO spin-stabilized spacecraft capable of conducting eleven experiments in studying the sun, the earth, and other space objects. The OSO provides controlled electric power, thermal control, a telemetry and command interface, tape-recorded data storage, and precisely timed orbital and orientation information. A chart indicating experiments carried out on nine OSO missions is included.
A wide variety of problems in solar physics will be attacked with coordinated observations made by the following instruments on Skylab: a white light coronagraph, a spectrograph for the 950-3900 A range, a spectrometer-spectroheliometer for the 300-1300 A range, a spectroheliograph for 150-650 A, X-ray telescopes, and supporting instrumentation. There will be complementary measurements from the ground and from space with 1-sec angular resolution on the sun. A coordinated program of correlative ground-based observations, sounding rocket launches, and observations from other spacecraft is being developed to provide calibration in orbit and simultaneous observations of solar phenomena over a broad range of the electromagnetic spectrum.
