Gemini 12 Crew Preparation

Buzz Aldrin practices stowing equipment ahead of Gemini 12, the final flight of Project Gemini. Aldrin's three spacewalks on the mission finally solved the exhaustion problems that had plagued earlier astronauts, thanks to new handholds, foot restraints, and underwater training that simulated weightlessness — techniques that became standard practice for every spacewalk that followed, including those of the Apollo program.
