OV1-17

NSSDCA/COSPAR ID: 1969-025A

Description

OV1-17 was one of four research satellites injected into orbit simultaneously from a single launch vehicle. The spacecraft was an 81-cm-long cylinder measuring 69 cm in diameter and was fitted with hemispheric multifaced solar panel domes on either end. Proper satellite orientation was maintained by a gravity-gradient stabilization system consisting of three 15.5-m-long horizontal booms forming a 'y' and two 19-m-long vertical booms. OV1-17 carried a variety of experiments to measure incoming solar electromagnetic radiation and the reaction of such radiation with the earth's outer atmosphere. Included were instrumentation for making (1) solar x-ray, particle, and electric field measurements, (2) horizontal dayglow and nightglow measurements, and (3) extremely low-frequency radio propagation studies. The spacecraft was also fitted with a meteor trail calibration beacon and a panel of 14 cadmium-sulfide solar cells to evaluate the performance and radiation resistance of such cells in a space environment. The spacecraft failed to achieve proper stabilization, thereby reducing the applicability of data from many of the experiments. OV1-17 reentered the earth's atmosphere on March 5, 1970.
