STS-41 crewmembers conduct DSO 0474 Retinal Photography on OV-103’s middeck

STS041-02-015 (6-10 Oct. 1990) --- A 35mm scene showing astronauts Robert D. Cabana (right), STS-41 pilot, and Bruce E. Melnick, mission specialist, participating in a detailed supplemental objective for STS-41 involving retinal photography. The hypothesis of this experiment is that retinal photographs taken on orbit will show evidence of increased intracranial pressure (ICP) and the evidence of increased ICP and the development of Space Adaptation Syndrome (SAS) will be correlated. SAS has been a subject of on-orbit analysis since the early days of space shuttle.
