Gemini 10 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 10 made a successful rendezvous and docking with the Agena 10 target. After undocking with Agena 10, the Gemini crew rendezvoused with Agena 8 without the use of radar. During the second of two EVA's, Collins used a hand-held maneuvering unit to fly to Agena 8, where he recovered a scientific package. Gemini 10 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.
