Crew Efficiency on First Exposure to Zero-Gravity (SKYCREW)
Research Area:
Behavior and performance
Neurophysiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Soon after reaching orbit several crewmembers of Apollo flights, as well as Russian cosmonauts, have reported symptoms of malaise or stomach discomfort, occasionally reaching the point of vomiting. While these symptoms have always disappeared after a few days, they have generated some concern about the ability of crewmen to work efficiently in the first few days of a space mission. This was a particularly important consideration for the future Shuttle operations, since many flights were to be limited to about seven days in orbit. The objective of this experiment was to make a reasonably objective analysis of crew efficiency during the first few days in-flight. This was accomplished using an 'activation' schedule which was prepared preflight for each crew.
