Head and Eye Motion During Ascent and Entry (DSO 403)
Principal Investigator
Research Area:
Species Studied
Scientific Name: Homo sapiens Species: Human

The objective of this investigation was to monitor and record horizontal and vertical extraocular eye motion (EOM) during prelaunch, launch, immediately postlaunch and pre-entry, entry-landing and immediately post landing. Recording of periods of horizontal head oscillation in each phase were also made. The investigator sought any acute changes in ocular motion, appearance of abnormal nystagmus or oscillopsia, or any change in horizontal vestibulo-ocular reflex.

An additional objective of this experiment was to demonstrate alternative hardware for measurement of horizontal head motion on ascent/entry and horizontal and vertical head motion on orbit.
