Gemini 12 Crew

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

Objectives

By the time of the last 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 by­now 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.

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.

Experiments

The 14 scientific experiments were (1) frog egg growth under zero-g, (2) synoptic terrain photography, (3) synoptic weather photography, (4) nuclear emulsions, (5) airglow horizon photography, (6) UV astronomical photography, and (7) dim sky photography. Two micrometeorite collection experiments, as well as three space phenomena photography experiments, were not fully completed.

Reentry

The capsule was controlled on reentry by computer and splashed down 4.8 kilometers from its target.

The Gemini 12 mission was supported by the following U.S. Department of Defense resources; 9,775 personnel, 65 aircraft and 12 ships.
