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 from their respiration and provided them with fresh oxygen." One of the male mice died (A-3352
[) during the trip, and the four survivors were euthanized and dissected for their expected biological information upon their return from the Moon.
The three astronauts and the five mice were the last Earthlings to travel to and orbit the Moon. Evans and the five mice share two living-being spaceflight records, the longest amount of time spent in lunar orbit (147 hours 43 minutes), and the most lunar orbits completed (75).]
Mission
Apollo 17 launched December 7, 1972, and returned to Earth on December 19. A biological cosmic ray experiment (BIOCORE) carried the five pocket mice (''Perognathus longimembris''), a species chosen for the experiment because they had well documented biological responses. 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. Four of the five mice survived the flight; the cause of death of the fifth was not determined.
After their return to Earth, the four remaining live mice were euthanized and dissected. Although lesions in the scalp and liver were detected, they appeared to be unrelated to one another and were not thought to be the result of cosmic rays. No damage was found in the mice's retinas
