EXPERIMENT TITLE/NUMBER : 



PROGRAM/MISSION : Little Joe 4 



CLASSIFICATION : Animal - Rhesus monkey ( Macaca mulatta ) 



DISCIPLINE(S) : Behavioral science, Environmental health 



OBJECTIVES : To observe the physiological effects of acceleration on a small 

 primate, particularly in the areas applying to the effects of the rapid onset 

 of reverse acceleration during abort at maximum dynamic pressure. 



PROTOCOL : A performance test that involved tapping a telegraph key-like 

 switch each time a red light flashed in the capsule was included. 



EQUIPMENT : Rhesus monkey container (biopack). 



RESULTS : The monkey was sent to an altitude of 14,700 m. The performance 

 test was a success. There were no other findings of note. 



CONCLUSIONS : This experiment verified the adequacy of flight equipment to be 

 used in Project Mercury and showed the biomedical effects of acceleration 

 experienced during the abort of Mercury flight after liftoff not to be 

 adverse.
