Space motion sickness monitoring experiment - Spacelab 1

A detailed firsthand report on symptoms and signs of space motion sickness and fluid shift observed by four specially trained crewmembers during Shuttle/Spacelab 1, launched on November 28, 1983 is presented. Results show that three crewmen experienced persistent overall discomfort and vomited repeatedly. Symptom pattern was generally similar to that seen in the individuals preflight, except that prodromalnausea was brief or absent in some cases. Symptoms were clearly modulated by head movement, were exacerbated by unfamiliar visual cues, and could be reduced by physical restraint providing contact cues around the body. The results support the view that space sickness is a form of motion sickness.
