The Frog Otolith Experiment Package (FOEP) contained all apparatus necessary to assure survival of two frogs. Specimens were housed in a water-filled, self-contained centrifuge which supplied the test acceleration during orbit. The FOEP was designed for flight as part of the Apollo Applications Program; however, the package was equipped for flight on an unmanned spacecraft.

Orbiting Frog Otolith. The satellite carrying the OFO-A experiment remained in orbit for almost seven days. Recovery of the spacecraft was not planned. The payload was the Frog Otolith Experiment Package (FOEP). The objective of the experiment was to investigate the effect of microgravity on the otolith, a sensory organ that responds to changes in an animal's orientation within the Earth's gravitational field. Two bullfrogs (Rana catesbeiana) were used as experimental subjects in the flight experiment. Additional Details: OFO 1.
