OV3-3

ResourceID

Description

The OV3-3 spacecraft was placed into a polar orbit to measure trapped and precipitating particles and
correlated electromagnetic wave fields. The spacecraft was spin stabilized at 8 rpm, and its systems performed
well for 14 months, until September 1967 when the onboard tape recorder failed. After that time, low-latitude,
real-time tracking continued into 1969 when the spacecraft was deactivated.
