Orbiting Vehicle 1-9 (also known as OV1-9), launched 11 December 1966 along with OV1-10, was the ninth (sixth successful) satellite in the OV1 series of the United States Air Force's Orbiting Vehicle program. OV1-9 recorded low frequency radio emissions and particle radiation in Earth's exosphere; the satellite also collected data on the impact of long-term radiation on biological samples and tissue equivalents. OV1-9 returned the first proof that Earth has an electric field.
