PRINCIPAL TNVESTIGATOR(S ): James P. Henry 



EXPERIMENT TITLE/NUMBER : 



PROGRAM/MISSION : Blossom 7 



CLASSIFICATION : Animal - Mouse 



DISCIPLINE(S) : Behavioral science, Environmental health 



OBJECTIVES : To study the effects of zero gravity on animal behavior. 



PROTOCOL : The mouse was placed in the clear container unanesthetized, and 

 photographed at short intervals of 1 second duration at 4 second intervals. 



EQUIPMENT : Photographic equipment, pie-wedge-shaped mouse chamber of 

 Plexiglass, an accelerometer . 



RESULTS : The parachute deployed, but failed to open and the mouse was killed 

 on impact, but the film was recovered. The pictures showed the mouse floating 

 around, with tactile and visual senses allowing orientation during a brief 

 period of weightlessness. 



CONCLUSIONS : This experiment contradicted the popular theory that zero-g 

 would cause disorientation.
