Armstrong's actions drew praise in the agency and may have been a factor for tapping him as the first man on the moon. Gemini 9A, launched June 3, , was supposed to dock with an Agena target, but astronauts Eugene Cernan and Tom Stafford discovered a part of the spacecraft had not deployed as planned.
Cernan's planned spacewalk had to be cut short when the astronaut struggled to don a maneuvering backpack outside. The astronauts successfully rendezvoused with an Agena target, but used more fuel than anticipated — canceling further maneuvers.
Collins also performed two spacewalks, again encountering difficulties with the lack of handholds. Gemini 11 docked with an Agena after its launch on Sept.
Dick Gordon performed two spacewalks while commander Pete Conrad remained inside the spacecraft. Among other achievements, the astronauts boosted their spacecraft to a higher orbit and did an artificial gravity test using a tether.
Finishing up the program was Gemini 12, which launched Nov. Aldrin performed three spacewalks while the astronauts did docking maneuvers with their Agena.
With this and the rest of the Gemini program accomplished, NASA felt ready to begin its reach for the moon during the Apollo program.

NASA's public affairs office issued a statement in declaring "Jeh-mih-nee" the "official" pronunciation.
The Apollo program was conceived in early as a three-man spacecraft to follow Project Mercury. Kennedy on May 25, , it became evident to NASA officials that a follow-on to the Mercury program was required to develop certain spaceflight capabilities in support of Apollo.
Chamberlin designed the Gemini capsule, which carried a crew of two. He was previously the chief aerodynamicist on Avro Canada 's Avro Arrow fighter interceptor program.
Space Task Group's engineering division in charge of Gemini. Astronaut Gus Grissom was heavily involved in the development and design of the Gemini spacecraft.
What other Mercury astronauts dubbed "Gusmobile" was so designed around Grissom's 5'6" body that, when NASA discovered in that 14 of 16 astronauts would not fit in the spacecraft, the interior had to be redesigned.
George E. William C. Guenter Wendt was a McDonnell engineer who supervised launch preparations for both the Mercury and Gemini programs and would go on to do the same when the Apollo program launched crews.
His team was responsible for completion of the complex pad close-out procedures just prior to spacecraft launch, and he was the last person the astronauts would see prior to closing the hatch.
The astronauts appreciated his taking absolute authority over, and responsibility for, the condition of the spacecraft and developed a good-humored rapport with him.
NASA selected McDonnell Aircraft , which had been the prime contractor for the Project Mercury capsule, in to build the Gemini capsule, the first of which was delivered in The Gemini crew capsule referred to as the Reentry Module was essentially an enlarged version of the Mercury capsule.
Unlike Mercury, the retrorockets , electrical power, propulsion systems, oxygen, and water were located in a detachable Adapter Module behind the Reentry Module.
A major design improvement in Gemini was to locate all internal spacecraft systems in modular components, which could be independently tested and replaced when necessary, without removing or disturbing other already tested components.
Many components in the capsule itself were reachable through their own small access doors. Unlike Mercury, Gemini used completely solid-state electronics, and its modular design made it easy to repair.
Gemini's emergency launch escape system did not use an escape tower powered by a solid-fuel rocket , but instead used aircraft-style ejection seats.
The tower was heavy and complicated, and NASA engineers reasoned that they could do away with it as the Titan II's hypergolic propellants would burn immediately on contact.
A Titan II booster explosion had a smaller blast effect and flame than on the cryogenically fueled Atlas and Saturn. Ejection seats were sufficient to separate the astronauts from a malfunctioning launch vehicle.
At higher altitudes, where the ejection seats could not be used, the astronauts would return to Earth inside the spacecraft, which would separate from the launch vehicle.
The main proponent of using ejection seats was Chamberlin, who had never liked the Mercury escape tower and wished to use a simpler alternative that would also reduce weight.
He reviewed several films of Atlas and Titan II ICBM failures, which he used to estimate the approximate size of a fireball produced by an exploding launch vehicle and from this he gauged that the Titan II would produce a much smaller explosion, thus the spacecraft could get away with ejection seats.
Maxime Faget , the designer of the Mercury LES, was on the other hand less-than-enthusiastic about this setup.
Aside from the possibility of the ejection seats seriously injuring the astronauts, they would also only be usable for about 40 seconds after liftoff, by which point the booster would be attaining Mach 1 speed and ejection would no longer be possible.
He was also concerned about the astronauts being launched through the Titan's exhaust plume if they ejected in-flight and later added, "The best thing about Gemini was that they never had to make an escape.
The Gemini ejection system was never tested with the Gemini cabin pressurized with pure oxygen, as it was prior to launch. In January , the fatal Apollo 1 fire demonstrated that pressurizing a spacecraft with pure oxygen created an extremely dangerous fire hazard.
Stafford commented on the Gemini 6 launch abort in December , when he and command pilot Wally Schirra nearly ejected from the spacecraft:.
So it turns out what we would have seen, had we had to do that, would have been two Roman candles going out, because we were 15 or 16 psi, pure oxygen, soaking in that for an hour and a half.
You remember the tragic fire we had at the Cape. Jesus, with that fire going off and that, it would have burned the suits.
Everything was soaked in oxygen. So thank God. That was another thing: NASA never tested it under the conditions that they would have had if they would have had to eject.
They did have some tests at China Lake where they had a simulated mock-up of Gemini capsule, but what they did is fill it full of nitrogen.
They didn't have it filled full of oxygen in the sled test they had. Gemini was the first astronaut-carrying spacecraft to include an onboard computer, the Gemini Guidance Computer , to facilitate management and control of mission maneuvers.
The Gemini Guidance Computer weighed Its core memory had addresses , each containing a bit word composed of three bit "syllables".
All numeric data was bit two's-complement integers sometimes used as fixed-point numbers , either stored in the first two syllables of a word or in the accumulator.
Instructions always with a 4-bit opcode and 9 bits of operand could go in any syllable. Unlike Mercury, Gemini used in-flight radar and an artificial horizon , similar to those used in the aviation industry.
Gemini added control of the spacecraft's translation forward, backward, up, down, and sideways with a pair of T-shaped handles one for each crew member.
Translation control enabled rendezvous and docking , and crew control of the flight path. The same controller types were also used in the Apollo spacecraft.
The original intention for Gemini was to land on solid ground instead of at sea, using a Rogallo wing rather than a parachute, with the crew seated upright controlling the forward motion of the craft.
To facilitate this, the airfoil did not attach just to the nose of the craft, but to an additional attachment point for balance near the heat shield.
This cord was covered by a strip of metal which ran between the twin hatches. The capsule was suspended at an angle closer to horizontal, so that a side of the heat shield contacted the water first.
This eliminated the need for the landing bag cushion used in the Mercury capsule. The Retro module contained four solid-fuel TE-M StarE retrorockets, each spherical in shape except for its rocket nozzle, which were structurally attached to two beams that reached across the diameter of the retro module, crossing at right angles in the center.
Abort procedures at certain periods during lift-off would cause them to fire at the same time, thrusting the Descent module away from the Titan rocket.
Translation control allowed changing orbital inclination and altitude, necessary to perform space rendezvous with other craft, and docking with the Agena Target Vehicle ATV , with its own rocket engine which could be used to perform greater orbit changes.
Early short-duration missions had their electrical power supplied by batteries; later endurance missions used the first fuel cells in crewed spacecraft.
Gemini was in some regards more advanced than Apollo because the latter program began almost a year earlier.
It became known as a "pilot's spacecraft" due to its assortment of jet fighter-like features, in no small part due to Gus Grissom's influence over the design, and it was at this point where the US crewed space program clearly began showing its superiority over that of the Soviet Union with long duration flight, rendezvous, and extravehicular capability.
However, the Titan had considerable difficulty being man-rated due to early problems with pogo oscillation.
The launch vehicle used a radio guidance system that was unique to launches from Cape Kennedy. Deke Slayton , as director of flight crew operations, had primary responsibility for assigning crews for the Gemini program.
Each flight had a primary crew and backup crew, and the backup crew would rotate to primary crew status three flights later.
Slayton intended for first choice of mission commands to be given to the four remaining active astronauts of the Mercury Seven : Alan Shepard , Grissom, Cooper, and Schirra.
Slayton himself continued to be grounded due to a heart problem. Titles used for the left-hand command and right-hand seat crew positions were taken from the U.
Air Force pilot ratings , Command Pilot and Pilot. Sixteen astronauts flew on 10 crewed Gemini missions:. The backup crew for Gemini 3 was Grissom and Borman, who were also slated for Gemini 6 , to be the first long-duration mission.
Finally Conrad and Lovell were assigned as the backup crew for Gemini 4. Delays in the production of the Agena Target Vehicle caused the first rearrangement of the crew rotation.
The Schirra and Young mission was bumped to Gemini 6 and they became the backup crew for Shepard and Stafford.
Grissom and Borman then had their long-duration mission assigned to Gemini 5.Kühlmittel für die beiden Learn more here mit jeweils einer Pumpe waren Silikonester.
