    The Douglas space simulator is a 39-foot-diameter sphere with a pumping speed adequate for manned operation while maintaining a simulated space vacuum. Man-rating of the simulator will permit personnel safely to occupy the chamber and to enter or leave it quickly. The simulator will be modified to provide a two-stage repressurization system, additional penetrations for life-support systems, and a two-compartment air lock. The primary and secondary air locks will be used to enter the chamber without breaking vacuum and as a backup chamber for observer and rescue personnel. The primary lock may also be used as an independent test chamber. A life-support system will be provided to support personnel inside the chamber and locks. Suitable biomedical monitoring of chamber occupants will be provided.
