Gemini control systems

Big Gemini was proposed to NASA by McDonnell Douglas in August 1969 as an advanced version of the Gemini spacecraft system.
It was intended to provide large-capacity, all-purpose access to space, including missions that ultimately used Apollo or the Space Shuttle.

Gemini 1 was the first mission in NASA's Gemini program.
An uncrewed test flight of the Gemini spacecraft, its main objectives were to test the structural integrity of the new spacecraft and modified Titan II launch vehicle.
It was also the first test of the new tracking and communication systems for the Gemini program and provided training for the ground support crews for the first crewed missions.

Gemini 11 was the ninth crewed spaceflight mission of NASA's Project Gemini, which flew from September 12 to 15, 1966.
It was the 17th crewed American flight and the 25th spaceflight to that time.
Astronauts Charles Pete Conrad Jr. and Richard F.
Gordon Jr. performed the first direct-ascent rendezvous with an Agena Target Vehicle, docking with it 1 hour 34 minutes after launch; used the Agena rocket engine to achieve a record high-apogee Earth orbit; and created a small amount of artificial gravity by spinning the two spacecraft connected by a tether.
Gordon also performed two extra-vehicular activities for a total of 2 hours 41 minutes.

Gemini 12 was a 1966 crewed spaceflight in NASA's Project Gemini.
It was the 10th and final crewed Gemini flight, the 18th crewed American spaceflight, and the 26th spaceflight of all time, including X-15 flights over 100 kilometers (54 nmi).
Commanded by Gemini VII veteran James A.
Lovell, the flight featured three periods of extravehicular activity (EVA) by rookie Edwin Buzz Aldrin, lasting a total of 5 hours and 30 minutes.
It also achieved the fifth rendezvous and fourth docking with an Agena target vehicle.

Gemini 2 was the second spaceflight of the American human spaceflight program Project Gemini, and was launched and recovered on January 19, 1965.
Gemini 2, like Gemini 1, was an uncrewed 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 into the Gemini B configuration, and was subsequently launched on another suborbital flight, along with OPS 0855, as a test for the US Air Force Manned Orbital Laboratory.
Gemini spacecraft no. 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; it would also be the only space capsule to be reused until Crew Dragon Endeavour was launched a second time in 2021.

Gemini 3 was the first crewed mission in NASA's Project Gemini and was the first time two American astronauts flew together into space.
On March 23, 1965, astronauts Gus Grissom and John Young flew three low Earth orbits in their spacecraft, which they nicknamed Molly Brown.
It was the first U.S. mission in which the crew fired thrusters to change the size and shape of their orbit, a key test of spacecraft maneuverability vital for planned flights to the Moon.
It was also the final crewed flight controlled from Cape Kennedy Air Force Station in Florida, before mission control functions were moved to a new control center at the newly opened Manned Spacecraft Center in Houston, Texas.

Gemini 4 was the second crewed spaceflight in NASA's Project Gemini, occurring in June 1965.
It was the tenth crewed American spaceflight.
Astronauts James McDivitt and Ed White circled the Earth 66 times in four days, making it the first US flight to approach the five-day flight of the Soviet Vostok 5.
The highlight of the mission was the first space walk by an American, during which White floated free outside the spacecraft, tethered to it, for approximately 23 minutes.

Gemini 7 was a 1965 crewed spaceflight in NASA's Gemini program.
It was the fourth crewed Gemini flight, the twelfth crewed American spaceflight, and the twenty-first crewed spaceflight including Soviet flights and X-15 flights above the Kármán line.
The crew of Frank Borman and Jim Lovell spent nearly 14 days in space, making a total of 206 orbits.
Their spacecraft was the passive target for the first crewed space rendezvous performed by the crew of Gemini 6A.

Gemini 8 was the sixth crewed spaceflight in NASA's Gemini program.
It was launched on March 16, 1966, and was the 14th crewed American flight and the 22nd crewed spaceflight overall.
The mission conducted the first docking of two spacecraft in orbit, but also suffered the first critical in-space system failure of a U.S. spacecraft which threatened the lives of the astronauts and required an immediate abort of the mission.
The crew returned to Earth safely.

Gemini 9A was a 1966 crewed spaceflight in NASA's Gemini program.
It was the seventh crewed Gemini flight, the 13th crewed American flight and the 23rd spaceflight of all time.
The original crew for Gemini 9, command pilot Elliot See and pilot Charles Bassett, were killed in a crash on February 28, 1966, while flying a T-38 jet trainer to the McDonnell Aircraft plant in St.
Louis, Missouri to inspect their spacecraft.
Their deaths promoted the backup crew, Thomas P.
Stafford and Eugene Cernan, to the prime crew.
The mission was renamed Gemini 9A after the original May 17 launch was scrubbed when the mission's Agena Target Vehicle was destroyed after a launch failure.
The mission was flown June 3–6, 1966, after launch of the backup Augmented Target Docking Adaptor (ATDA).
Stafford and Cernan rendezvoused with the ATDA, but were unable to dock with it because the nose fairing had failed to eject from the docking target due to a launch preparation error.
Cernan performed a two-hour extravehicular activity, during which it was planned for him to demonstrate free flight in a self-contained rocket pack, the USAF Astronaut Maneuvering Unit.
He was unable to accomplish this due to stress, fatigue, and overheating.

The Gemini Guidance Computer was a digital, serial computer designed for Project Gemini, America's second human spaceflight project.
The computer, which facilitated the control of mission maneuvers, was designed by the IBM Federal Systems Division.

The Gemini spacesuit is a spacesuit worn by American astronauts for launch, in-flight activities and landing.
It was designed by NASA based on the X-15 high-altitude pressure suit.
All Gemini spacesuits were developed and manufactured by the David Clark Company in Worcester, Massachusetts.
