  skos:definition """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
celestial sphere for direction and intensity of UV light, X-rays, and gamma
radiation. The OSO 1 was the first satellite to have pointed instruments and
onboard tape recorders for data storage.  The OSO 1 platform consisted of a
sail section, which pointed two experiments continuously toward the sun,
supplying power to the experiments from the solar batteries and rechargeable
chemical batteries; and a wheel section, which spun about an axis perpendicular
to the pointing direction of the sail and carried seven experiments. Attitude
adjustment was performed by gas jets. Data were simultaneously recorded on tape
and transmitted by FM telemetry. A command system provided for 10 ground-based
commands. The spacecraft performed normally until the second onboard tape
recorder failed May 15, 1962. The spacecraft provided real-time data until May
1964, when the power cells failed.
