  Gemini 4
Gemini IV's problem was compounded by its limited fuel supply; the Spacecraft 4 tanks were only half the size of later models, and the fuel had to be conserved for the fail-safe maneuvers.
Gemini IV was the first of the program's longer missions, and it imposed a set of new demands on ground control, which moved for the first time into a three-shift operation.
Gemini IV was also the first mission to employ systematic methods to gather, evaluate, and publish information quickly, another demand imposed by longer flights and shorter intervals between missions.

 Project Gemini - Wikipedia, the free encyclopedia
The original intention was for Gemini to use a paraglider instead of a parachute, and the crew to be seated upright controlling the forward motion of the craft before its landing.
Gemini is also the name of the third constellation of the Zodiac and its twin stars, Castor and Pollux.
Gemini was the first American manned spacecraft to include an onboard computer, the Gemini Guidance Computer, to facilitate management and control of mission maneuvers.

Project Gemini, which used a two-man spacecraft, bridged the gap between the Mercury program, the first tentative steps into space, and the Apollo program, which landed men on the moon.
Gemini's primary objectives were to investigate the problems of long-duration spaceflight, to develop techniques for rendezvous and docking with target vehicles, and to conduct extravehicular operations.
Two of these, Gemini 6 and 7, were simultaneous so that the capsules could rendezvous in space and orbit in close formation.

The Gemini program was a whole series of manned spaceflights as an intermediate step between the Mercury and Apollo programs to test that astronauts could spend sufficient time in space to undertake a return trip to the Moon and to practice the rendezvous and docking techniques needed for such a mission.
Gemini VII was now to be their rendezvous vehicle and they successfully brought the two craft to within one foot of each other - Gemini VI then returned to Earth the next day after 16 orbits and a 25hrs:51mins:54 sec total elapsed time mission.
Gemini VII, was launched before Gemini VI as outlined above and after the redezvous exercise stayed on in space on an endurance mission to prove man could live and function effectively in the weightless environment for sufficient time to undertake a lunar mission.

Project Gemini was a transitional step between the pioneering Mercury Program and the actual landing a man on the moon.
The main objectives of the ten Gemini missions spanning a period of 20 months from 1965 to 1966, were to learn how to "fly" a spacecraft by 1) maneuvering it in orbit and by 2) rendezvousing and docking with other vehicles, which were essential skills for the later Apollo missions.
One of these missions, Gemini VIII, nearly killed the man who would go on to be the first person to walk on the moon, Neil Armstrong.

 Manned Space Chronology: Gemini 4
Early in the mission, a decision was made to cancel an attempted rendezvous with the spent Titan II second stage because too much OAMS fuel had been used up during initial stationkeeping operations.
It was also discovered that when the Gemini 4 spacecraft's thrusters were fired when on the same orbital path as the spent Titan II second stage, the spacecraft moved farther away from, and not closer to, the target.
For the duration of the spacewalk, White remained tethered to the Gemini 4 spacecraft by a 25-foot life support umbilical line.

GEMINI was not pure pioneering like MERCURY, nor did it have the excitement of APOLLO.
GEMINI's primary purpose was to demonstrate space rendezvous and docking - techniques that would be used during APOLLO, when the lunar lander would separate from the command module in orbit around the Moon, then meet up with it again after the astronauts left the lunar surface.
GEMINI astronauts also made the first forays outside their spacecraft, which required a new spacesuit design.
