Basic requirements for survival of mice in a sealed atmosphere.

This report presents the results of P series of experiments conducted to determine the basic requirements of mice in a * sealed atmosphere. The studies were undertaken as a preliminary to the design of a small container suitable for placement in an orbital rocket. Oxygen consumption of a mouse was determined in the resting state and during vwrious states of activity for time periods ranging from 1 hour to 2 weeks. The basic requirements of food, water, oxygen, and soda lime were also established. Evidence suggests that a mouse can live under fairly comfortable conditions in a sealed compartment for a thirty-day period.
