Collection Item Summary:

This hatch closing lanyard, flown on Gemini XII, November 11-15, 1966, was used with the hatch closing device, and allowed the astronaut at the conclusion of an EVA, extravehicular activity or "spacewalk," to pull down the hatch. Commanded by Jim Lovell and piloted by Edwin "Buzz" Aldrin, Gemini XII was launched on a 4-day, 59-orbit mission. Highlights included 3 extra-vehicular activities (EVAs) by Aldrin, 5 hours 30 minutes total. Aldrin made extensive use of handholds and footholds to prevent unwanted movement during his tasks, and his techniques were an important milestone toward effective astronaut use of EVA.

NASA transferred this device to the Smithsonian with the Gemini XII spacecraft in 1968.
