OFO - Orbiting Frog Otolith
American biology satellite. One launch, 1970.11.09. 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.

AKA: Orbiting Frog Otolith.
Gross mass: 133 kg (293 lb).
First Launch: 1970.11.09.
Number: 1 .

Associated Launch Sites
  • Wallops Island Small NASA launch site for sounding rocket launches and occasional Scout launches to orbit. Air launches are conducted from the Drop Zone Wallops Island, 37.00 N 72.0 W. With the last orbital launch in 1985 and the decline in sounding rocket launches, Wallops fell into near-disuse as a launch center. Its fortunes revised with the establishment of Mid-Atlantic Regional Spaceport in 2005 and orbital launches resumed in 2010. More...

  • OFO 1 - . Payload: OFO 1 / RM 1. Mass: 133 kg (293 lb). Nation: USA. Agency: NASA Ames. Class: Biology. Type: Biology satellite. Spacecraft: OFO. Decay Date: 1971-05-09 . USAF Sat Cat: 4690 . COSPAR: 1970-094A. Apogee: 518 km (321 mi). Perigee: 304 km (188 mi). Inclination: 37.4000 deg. Period: 92.60 min. 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: here....
