What did Buzz Aldrin do in Gemini 12?

In Gemini 12, Buzz Aldrin served as the pilot alongside commander Jim Lovell. The mission, launched in November 1966, focused on demonstrating extravehicular activity (EVA) techniques and improving spacewalk efficiency. Aldrin successfully conducted a series of spacewalks, including the first-ever use of a maneuverable handrail, which allowed him to perform tasks outside the spacecraft more effectively. This mission helped pave the way for future lunar missions by enhancing astronaut abilities during EVAs.
