Fe, Fi, Fo, Fum, and Phooey

Fe, Fi, Fo, Fum, and Phooey were five mice who traveled to the Moon and circled it 75 times on the 1972 Apollo 17 mission.

NASA gave them identification numbers A3305, A3326, A3352, A3356, and A3400, and their nicknames were given by the Apollo 17 crew (Eugene Cernan, Harrison Schmitt, and Ronald Evans).

The mice travelled in individual compartments of tubes inside an aluminium container with "a sufficient food supply, temperature control, and a reserve of potassium superoxide that absorbed the CO2 from their respiration and provided them with fresh oxygen.

Some advantages of the species included their small size, ease of maintenance in an isolated state (requiring no drinking water for the expected duration of the mission and producing highly concentrated waste), and their proven capability of withstanding environmental stress.

Fe, Fi, Fo, Fum, and Phooey had been implanted with radiation monitors under their scalps to see whether they would suffer damage from cosmic rays.

Five mice and three astronauts traveled to the Moon and returned to Earth in Apollo 17 's Command Module America , now on display at Space Center Houston .
NASA astronaut Ronald Evans and the mice orbited the Moon together for over six days in 1972.
