PROGRAM/MISSION : Mercury 7, MA-7 



CLASSIFICATION : Human 



DISCIPLINE(S) : Environmental health 



OBJECTIVES : To evaluate the performance of the man-spacecraft system in a 

 three-pass orbital mission, to evaluate the effects of space flight on the 

 astronaut, and to obtain the astronaut's opinions on the operational 

 suitability of the spacecraft systems. 



PROTOCOL : Pre- and postflight physical examinations were performed which 

 included routine and special laboratory tests, X-rays, retinal photography, 

 electrocardiography, electroencephalography, and special tests of the body's 

 balancing mechanism. A xylose tolerance test was performed inflight. 



EQUIPMENT : Two sets of EKG leads, rectal temperature thermistor, respiration 

 rate thermistor, blood pressure measuring system, inflight urine collection 

 device. 



RESULTS : No pulmonary atelectasis, no cosmic ray damage, nor any psychiatric 

 abnormalities were found. There were no abnormal vestibular or related gas- 

 trointestinal symptoms. Biochemical analysis confirmed the occurrence of a 

 moderate diuresis. 



CONCLUSIONS : All flight responses were considered to be within acceptable 

 physiological ranges. No disturbing body sensations were reported as a result 

 of weightlessness.
