Gemini X was launched on July 18, 1966, for a 3-day mission. Commander John Young and pilot Michael Collins orbited the Earth 43 times. On the third orbit, Gemini X made a successful rendezvous and docking with the Agena X target. After undocking with Agena X, the Gemini crew rendezvoused with Agena VIII without the use of radar. During the second of two EVA's, Collins used a hand-held maneuvering unit to fly to Agena VIII, where he recovered a scientific package. Gemini X marked the first flight to rendezvous with two different target vehicles.
This pouch was removed from the spacecraft after flight and was stored at the spacecraft manufacturer, McDonnell Aircraft Corporation. In 1968 it was sent to the Smithsonian with a large number of Gemini parts.
