Upon completion of the flight, the spacecraft impacted in the Atlantic ocean near Bermuda. The spacecraft was provided with continuous tracking and telemetry from Wallops Island and Bermuda. It studied the gravitational effect on time measurements (relativistic or Einstein redshift) by use of a hydrogen maser oscillator system (clock). This was to verify one of the results expected from Einstein`s general theory of relativity.
