was the experiment successful?
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 killed and dissected, and 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.

Fe, Fi, Fo, Fum, and Phooey [SEP] Mission
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 killed and dissected, and 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 or viscera. At the time of the publication of the Apollo 17 Preliminary Science Report their brains had not yet been examined, and subsequent studies however showed no significant effect on the mice's brains.
