1966: Gemini 12 (NASA)

Uploaded by iafastro on Apr 25, 2008
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 manoeuvers using the Agena propulsion system to change orbit, and demonstrate an automatic reentry.
By the completion of the previous Gemini flight, the programme still had not demonstrated that an astronaut could work easily and efficiently outside the spacecraft. In preparation for Gemini 12, 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 charts when a rendezvous radar failed. The climb to a higher orbit, however, was cancelled because of a problem with the Agena booster.

This mission made possible all those space walks to repair Hubble etc once the tools were invented

Aldrin has taken a lot of undeserved shit from commentators, but his PhD thesis from 1963, "Line-of-Sight Guidance Techniques for Manned Orbital Rendezvous" on rendezvous contains this dedication - ""In the hopes that this work may in some way contribute to their exploration of space, this work is dedicated to the crew members of this country's present and future manned space programs. If only I could join them in their exciting adventures!" - and he did! A super human being, a real SPACEMAN.

@nobadges i'm not sure, but i think the gemini is a latin word, and the pronouciation in latin is geminee
