Mission
Gemini 12 closed the program by solving its hardest unsolved problem: the spacewalk. Jim Lovell and Buzz Aldrin launched on 11 November 1966, rendezvoused with and docked their Agena, and then Aldrin — who had studied the problem so closely he was nicknamed 'Dr. Rendezvous' — stepped outside. Where earlier spacewalkers had exhausted themselves fighting to stay in place, Aldrin had handrails, tethers and foot restraints, and had rehearsed every task underwater in a tank that simulated weightlessness. Across three EVAs totalling five and a half hours he worked calmly and methodically, proving that an astronaut could do real work outside a spacecraft. It was the last piece Apollo needed. When Gemini 12 splashed down on 15 November, the program had, in twenty months, demonstrated every technique the Moon landings would require — and Aldrin would go on to be the second man to walk on the Moon.

With handrails, foot restraints and underwater training, Aldrin works calmly outside for 5.5 hours across three EVAs — proving useful work in the void is possible.
