OSO I began transmitting real-time data on solar observation after five weeks of intermittent transmittal. NASA scientists speculated that the cause of the reduction in the satellite's rate of spin from 50 rpm to 42 rpm, which caused the transmitter to restart, was either a result of bearing friction within the turning wheel or the slowing clown of the satellite's rotation because of its position with respect to the Earth's magnetic field.
