EXPERIMENT TITLE/NUMBER : 



PROGRAM/MISSION : Aerobee 3 



CLASSIFICATION : Animal - Capuchin monkey ( Cebus albifrons ) , mice 



DISCIPLINE(S) : Behavioral science, Environmental health 



OBJECTIVES : To study the effects of weightlessness on both orientation and 

 the physiology of the subject. 



PROTOCOL : The two monkeys were seated, anesthetized, and one placed to 



receive +G and the other placed to receive +G . ECG was taken from both 



z x 



animals. Attempts were made to measure arterial and venous pressures. Two 



mice, one normal and one labryrinthectomized, were placed in a rotating drum 



(4 rpm) and photographed. 



EQUIPMENT : Rotating mouse drum (with special shelf on one side), camera. 



RESULTS : Both monkeys and mice survived the flight without demonstrable ill 

 effects. The measurements of arterial and venous pressures failed. The 

 labrynthine-defective mouse did well, if given a foothold in the rotating drum 

 while the normal mouse clawed the air trying to get his balance. 



CONCLUSIONS : These were the first living creatures to survive spaceflight 

 conditions. Minimum uncoordination and disorientation is experienced as long 

 as the subject retains tactile and has visual references.
