The effects of cosmic particle radiation on pocket mice aboard Apollo XVII: VI. launch, flight, and recovery.

The final phase to fly five pocket mice in the Apollo XVII command module was carried out at the NASA Kennedy Space Center. Upon completion of the 13-d space flight, the package was removed from the spacecraft and, after having been purged with an oxygen-helium gas mixture, was flown to American Samo. Four of the five mice were recovered alive from the package. Analysis of the mouse that died during the flight revealed several factors that could have contributed to its death, the chief of which was massive hemorrhage in its middle ear cavities.

The effects of cosmic particle radiation on pocket mice aboard Apollo XVII: IV. engineering aspects of the experiment and results of animal tests.

A closed passive system independent of support from the spacecraft or its crew was developed to house five pocket mice for their flight on Apollo XVII. The reaction of potassium superoxide with carbon dioxide and water vapor to produce oxygen provided a habitable atmosphere within the experiment package. The performance of the system and the ability of the mice to survive the key preflight tests gave reasonable assurance that to mice would also withstand the Apollo flight.

Weightlessness and the developing frog egg.

This paper describes the results of the flight of fertilized frog eggs in the manned orbital flights Gemini 8 and Gemini 12. The experiment was designed to determine the effect of weightlessness or near weightlessness on the ability of the cell to divide normally and on subsequent differentiation and embryogenesis. Eggs were fixed periodically in flight so that recovered material could be carefully compared to simultaneous ground controls with respect to gross morphology and histology. Some embryos were recovered alive after 4 days in orbit. In general, no abnormalities were detected which were inconsistent with the controls. Death, shortly after recovery, of the embryos recovered alive in Gemini 12, remains unexplained. The protocol of the experiment and the experimental hardware is described. Rationale for future experiments is discussed.
