NASA has just published a whole lot of beutifully respored photographs from the 1960’s project Gemini. Here’s a better explanation from Universe Today:
Project Gemini followed the initial Project Mercury program and was the predecessor for the ambitious Apollo missions to the Moon, with ten crewed flights from 1965-1966. It used a two-man spacecraft and tested new technologies and procedures for the later Apollo missions such as precision atmospheric reentry, Extra Vehicular Activity (spacewalking), fuel cells to generate electricity and water, perfect the rendezvous and docking process between two spacecraft, new techniques for propelling and maneuvering two docked spacecraft and long-term human spaceflight. It featured the first spacewalk, the first rendezvous between two Gemini spacecraft, the first docking between a manned and unmanned vehicle, the first maneuver to change orbit and the first onboard computer.
