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

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