Rotator, Spacelab MVI Experiments, STS-42


Display Status:

This object is on display in the Moving Beyond Earth exhibition at the National Air and Space Museum in Washington, DC.

Collection Item Summary:

This rotator unit was the motorized base for the chair used in the Microgravity Vestibular Investigations during the first International Microgravity Laboratory mission, STS-42, on the Space Shuttle in 1992. The chair could be attached to the base in upright, sideways, or prone positions and then rotated back and forth or spun around. Different patterns of rotation stimulated different sensory responses that were recorded and analyzed to study the astronauts' adaptation to weightlessness.

NASA transferred this to the Museum in 2004.
