PROGRAM/MISSION : Mercury 4, MR-4 



CLASSIFICATION : Human 



DISCIPLINE(S) : Environmental health 



OBJECTIVES : To familiarize man with a brief but complete space flight 

 experience, to evaluate man's ability to perform as a functional unit during 

 space flight, and to study man's physiological reactions. 



PROTOCOL : Astronaut was given a complete physical examination on F-10 and 

 F-3, and a brief examination on the day of the flight. An examination was 

 also given on recovery. Several parameters were monitored inflight, including 

 heart rate, body temperature, and respiration. Urine was collected for post- 

 flight analysis. One week pref light, the astronaut was placed on a controlled 

 diet and on F-3 was placed on a low residue diet. A continuous record was 

 made of what the astronaut was doing during the flight. 



EQUIPMENT : Linear potentiometer with carbon impregnated rubber (indirect 

 respiration measurement), rectal thermistor (body temperature), EKG with low 

 impedence electrodes (for heart rate). No measurement was made of blood 

 pressure or of radiation exposure since the spacecraft was going below the Van 

 Allen belts. 



RESULTS : All physiological readings were normal. Peak responses were 

 maintained at critical inflight events. There was no evidence of motion 

 sickness, and no indication of body system dysfunction. 



CONCLUSIONS : There were no adverse physiological effects associated with 

 space flight, but futher investigations are needed.
