Question: When was the project 'Gemini' first introduced?
About the article "Space Race", section "Project Gemini".

Candidate passages:
The compact flash was first introduced by Bowens in the 1960s.
The new range called 'Gemini' include the Standard Gemini, The Gemini R and finally the Gemini Pro.
The powers range from 200w in the standard Gemini to 1500w in the Gemini Pro.
The Gemini flashes can be used with a wide range of reflectors and softboxes. 
Deke Slayton, as director of flight crew operations, had the main role in the choice of crews for the Gemini program.
With Gemini it became a procedure that each flight had a primary crew and backup crew, and that the backup crew would rotate to primary crew status three flights later.
Slayton also 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.
(John Glenn had retired from NASA in January 1964 and Scott Carpenter, who was blamed by some in NASA management for the problematic reentry of "Aurora 7", was on leave to participate in the Navy's SEALAB project and was grounded from flight in July 1964 due to an arm injury sustained in a motorbike accident.
Slayton himself continued to be grounded due to a heart problem.
)In late 1963, Slayton selected Shepard and Stafford for Gemini 3, McDivitt and White for Gemini 4, and Schirra and Young for Gemini 5 (which was to be the first Agena rendezvous mission).
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 now were the backup crew for Shepard and Stafford.
Grissom and Borman now had their long-duration mission assigned to Gemini 5.
The second rearrangement occurred when Shepard developed Ménière's disease, an inner ear problem.
Grissom was then moved to command Gemini 3.
Slayton felt that Young was a better personality match with Grissom and switched Stafford and Young.
Finally, Slayton tapped Cooper to command the long-duration Gemini 5.
Again for reasons of compatibility, he moved Conrad from backup commander of Gemini 4 to pilot of Gemini 5, and Borman to backup command of Gemini 4.
Finally he assigned Armstrong and Elliot See to be the backup crew for Gemini 5.
The third rearrangement of crew assignment occurred when Slayton felt that See wasn't up to the physical demands of EVA on Gemini 8.
He reassigned See to be the prime commander of Gemini 9 and put Scott as pilot of Gemini 8 and Charles Bassett as the pilot of Gemini 9.
The fourth and final rearrangement of the Gemini crew assignment occurred after the deaths of See and Bassett when their trainer jet crashed, ironically into a McDonnell building which held their Gemini 9 capsule in St. Louis.
The backup crew of Stafford and Cernan was then moved up to the new prime crew of the re-designated Gemini 9A.
Lovell and Aldrin were moved from being the backup crew of Gemini 10 to be the backup crew of Gemini 9.
This cleared the way through the crew rotation for Lovell and Aldrin to become the prime crew of Gemini 12.
Along with the deaths of Grissom, White, and Roger Chaffee in the fire of Apollo 1, this final arrangement helped determine the makeup of the first seven Apollo crews, and who would be in position for a chance to be the first to walk on the Moon. 
Gemini 2 was the second spaceflight of the American human spaceflight program Project Gemini.
"Gemini 2", like "Gemini 1", was an unmanned mission intended as a test flight of the Gemini spacecraft.
Unlike Gemini 1, which was placed into orbit, Gemini 2 made a suborbital flight, primarily intended to test the spacecraft's heat shield.
It was launched on a Titan II GLV rocket.
The spacecraft used for the Gemini 2 mission was later refurbished, and was subsequently launched on another suborbital flight, along with OPS 0855, as a test for the US Air Force Manned Orbital Laboratory.
Gemini 2 was the first craft to make more than one spaceflight since the X-15, and the only one until Space Shuttle "Columbia" flew its second mission in 1981. 
Gemini was an award winner in the 2009, 2010 and 2011 Code Project Members Choice Awards. 
Gemini 12 (officially Gemini XII) was a 1966 manned spaceflight in NASA's Project Gemini.
It was the 10th and final manned Gemini flight, the 18th manned American flight and, including X-15 flights over , the 26th spaceflight of all time.
