This is a Gemini ringsail (main) parachute test article. Manufactured by Northrop Ventura, it is made largely of nylon and is over 84 feet in diameter when fully deployed. Carried in the Rendezvous and Recovery Section at the front of the capsule, the ringsail parachute deployed shortly after this section was jettisoned at an altitude of about 10,500 feet during reentry. The National Aeronautics and Space Administration's Lewis Research Center transferred this artifact to NASM in 1968.
This object is not on display at the National Air and Space Museum. It is either on loan or in storage.
