Collection Item Summary:
The Gemini spacecraft had two windows, one in each hatch in front of each astronaut. This artifact is the outer frame and gasket for the left-hand window. The left seat on Gemini XII was occupied by James Lovell, mission command pilot. He flew with Edwin E. "Buzz" Aldrin Jr. on a four day mission in November 1966, the last in the Gemini series. That mission proved the feasibility of doing work on a zero-G EVA ("spacewalk") and rendezvoused and docked with an Agena target vehicle.
This window frame was shipped separately from the spacecraft when NASA transferred the latter to the Smithsonian in 1968.
