(2) To determine whether any difficulties experienced were severe enough to impair the astronauts’ ability to leave the spacecraft in the event of an emergency.Study DesignProspective cohort study.SettingNational Aeronautics and Space Administration’s Kennedy Space Center and Johnson Space Center.Subjects and MethodsFourteen crewmembers of 3 Space Shuttle missions that lasted about 1 week and 18 crewmembers of 8 International Space Station missions that lasted about 6 months were given brief vestibular examinations 1 to 5 hours after landing.
