Frog Otolith Experiment Package (FOEP)
The Frog Otolith Experiment Package (FOEP) contains all apparatus necessary to assure survival of two frogs. Specimens are housed in a water-filled, self-contained centrifuge which supplies the test acceleration during orbit. Frogs are demotorized to prevent dislodging of implanted electrodes and to reduce their metabolic rate. The FOEP was designed for flight as part of the Apollo Applications Program; however, the package is equipped for flight on an unmanned spacecraft.
Life Support System (LSS): The LSS maintains a regulated environment within the FOEP to assure the survival and normal functioning of two demotorized frogs. The lower bulkhead of the inner assembly structure provides mounting space for all life support equipment.
The package's dimensions were 18 in (457 mm) diameter × 18 in length, weighed 91 lb (41 kg) when loaded. Data acquisition consisted of ECG, body temperature, and vestibular activity. There was also a ground-based FOEP test unit which the FOEP could be connected preflight for ventilation and verification of environmental conditions prior to loading in the spacecraft.

Famous quotes containing the words frog and/or experiment:
“A frog he would a-wooing go,
Heigh ho! says Rowley,
Whether his mother would let him or no.
With a rowley, powley, gammon and spinach,
Heigh ho! says Anthony Rowley.”
