Larger Size NASA Gemini 12 Space Mission Embroidered Patch

This new format Gemini mission patch is larger and more detailed than those ordinarily available. Each comes in its own sealed packet. Each patch has a full colour header card with details of the mission on the reverse.

Gemini 12 (officially Gemini XII) was a 1966 manned spaceflight in NASA's Project Gemini. It was the 10th and final manned Gemini flight, the 18th manned American flight and, including X-15 flights over 100 kilometres (62 mi), the 26th spaceflight of all time.

At the completion of the previous Gemini flight, the program still had not demonstrated that an astronaut could work easily and efficiently outside the spacecraft. In preparation for Gemini XII new, improved restraints were added to the outside of the capsule, and a new technique—underwater training—was introduced, which would become a staple of future space-walk simulation. Aldrin's two-hour, 20-minute tethered space-walk, during which he photographed star fields, retrieved a micrometeorite collector and did other chores, at last demonstrated the feasibility of extravehicular activity. Two more stand-up EVAs also went smoothly, as did the by-now routine rendezvous and docking with an Agena which was done "manually" using the onboard computer and charts when a rendezvous radar failed. The climb to a higher orbit, however, was canceled because of a problem with the Agena booster.

Many documentaries afterward largely credit the spacewalk innovations, including the underwater training, to Aldrin himself.

Gemini 12 was designed to perform rendezvous and docking with the Agena target vehicle, to conduct three Extravehicular Activity (EVA) operations, to conduct a tethered stationkeeping exercise, to perform docked maneuvers using the Agena propulsion system to change orbit, and demonstrate an automatic reentry.
