Spacelab laboratory module in the cargo bay of the Space Shuttle Orbiter Columbia

(June 5, 1991) The laboratory module in the cargo bay of the Space Shuttle Orbiter Columbia was photographed during the Spacelab Life Science-1 (SLS-1) mission. SLS-1 was the first Spacelab mission dedicated solely to life sciences. The main purposes of the SLS-1 mission were (1) to study the mechanisms, magnitudes, and time courses of certain physiological changes that occur during space flight and (2) to investigate the consequences of the body's adaptation to microgravity and readjustment to Earth's gravity. The mission was designed to study the neurovestibular system (ie, involving the interactions of the vestibular system, eyes, and brain) and, particularly, to examine the causes of space motion sickness. The SLS-1 was launched aboard the Space Shuttle Orbiter Columbia
(STS-40) on June 5, 1991. (Source: NASA/Marshall Space Flight Center [Redstone Arsenal, Alabama]. NASA ID: 9135505. Public domain.)
