This harness was flown on the Gemini X mission, July 18-21, 1966. Piloted by John Young and Michael Collins, Gemini X rendezvoused and docked with an Agena vehicle, used the Agena engine to fly to an altitude of 763 km (474 mi) and rendezvoused with a second Agena left by Gemini VIII. During the mission, Michael Collins exited the spacecraft twice, once standing up in the seat to perform experiments, and once to float over to the Gemini VIII Agena to retrieve an experiment. The harness was used to fasten the long umbilical cord that provided oxygen and communications to Collins during his second “spacewalk.”
NASA transferred this harness to the Smithsonian in 1968.
