The Environmental Perception Characteristicsof Astronauts in Microgravity (ENPERCHAR) experiment studies how microgravity affects human perception and connection with the environment. Crew performance on scientific activities will be analyzed with reference to environmental psychology to investigate how microgravity may distort spatial awareness and perception. Analyses of verbal commentary while conducting experiments may reveal insights into the psychological effect of working in extreme environments. Understanding these effects are important for ensuring crewmembers can accurately perform tasks and ensure mission safety. Insights from this research could enhance general understanding of human perception.
