Question: How long did Buzz Aldrin work outside the spacecraft in November 1966?
About the article "Space Race", section "Project Gemini".

Candidate passages:
NASA planners invented the term "extra-vehicular activity" in the early 1960s for the Apollo program to land men on the Moon, because the astronauts would leave the spacecraft to collect lunar material samples and deploy scientific experiments.
To support this, and other Apollo objectives, the Gemini program was spun off to develop the capability for astronauts to work outside a two-man Earth orbiting spacecraft.
However, the Soviet Union was fiercely competitive in holding the early lead it had gained in manned spaceflight, so the Soviet Communist Party, led by Nikita Khrushchev, ordered the conversion of its single-pilot Vostok capsule into a two- or three-person craft named Voskhod, in order to compete with Gemini and Apollo.
The Soviets were able to launch two Voskhod capsules before U.S. was able to launch its first manned Gemini.
The Voskhod's avionics required cooling by cabin air to prevent overheating, therefore an airlock was required for the spacewalking cosmonaut to exit and re-enter the cabin while it remained pressurized.
By contrast, the Gemini avionics did not require air cooling, allowing the spacewalking astronaut to exit and re-enter the depressurized cabin through an open hatch.
Because of this, the American and Soviet space programs developed different definitions for the duration of an EVA.
The Soviet (now Russian) definition begins when the outer airlock hatch is open and the cosmonaut is in vacuum.
An American EVA began when the astronaut had at least his head outside the spacecraft.
The USA has changed its EVA definition since.
As they had with the first satellite and first man in space, the Soviets again stunned the world on March 18, 1965 with the first spacewalk (and the first EVA) performed by Alexey Leonov from the Voskhod 2 spacecraft, for 12 minutes outside the spacecraft.
Leonov had no means to control his motion other than pulling on his tether.
After the flight, he claimed this was easy, but his space suit ballooned from its internal pressure against the vacuum of space, stiffening so much that he could not activate the shutter on his chest-mounted camera.
At the end of his space walk, the suit stiffening caused a more serious problem: Leonov had to re-enter the capsule through the inflatable cloth airlock, in diameter and long.
After his spacewalk, he improperly entered the airlock head-first and got stuck sideways.
He could not get back in without reducing the pressure in his suit, risking "the bends".
This added another 12 minutes to his time in vacuum, and he was overheated by from the exertion.
It would be almost four years before the Soviets tried another EVA.
They misrepresented to the press how difficult Leonov found it to work in weightlessness and concealed the problems encountered until after the end of the Cold War.
The first American spacewalk was performed on June 3, 1965, by Edward H. White, II from the second manned Gemini flight, Gemini 4, for 21 minutes, on a tether.
White was the first to control his motion in space with a Hand-Held Maneuvering Unit, which worked well but only carried enough propellant for 20 seconds.
White found his tether useful for limiting his distance from the spacecraft but difficult to use for moving around, contrary to Leonov's claim.
However, a defect in the capsule's hatch latching mechanism caused difficulties opening and closing the hatch, which delayed the start of the EVA and put White and his crewmate at risk of not getting back to Earth alive.
No EVAs were planned on the next three Gemini flights.
The next EVA was planned to be made by David Scott on Gemini 8, but that mission had to be aborted due to a critical spacecraft malfunction before the EVA could be conducted.
Astronauts on the next three Gemini flights (Eugene Cernan, Michael Collins, and Richard Gordon), performed several EVAs, but none was able to successfully work for long periods outside the spacecraft without tiring and overheating.
Finally, on November 13, 1966, Edwin "Buzz" Aldrin became the first to successfully work in space without tiring, on the Gemini 12 last flight.
Aldrin worked outside the spacecraft for 2 hours and 6 minutes, in addition to two stand-up EVAs in the spacecraft hatch for an additional 3 hours and 24 minutes.
Aldrin's interest in scuba diving inspired the use of underwater EVA training to simulate weightlessness, which has been used ever since to allow astronauts to practice techniques of avoiding wasted muscle energy.
On January 16, 1969, the Soviet Union achieved the first EVA crew transfer from one spacecraft to another when Aleksei Yeliseyev and Yevgeny Khrunov transferred from Soyuz 5 to Soyuz 4, which were docked together.
This was the second Soviet EVA, and it would be almost another nine years before the Soviets performed their third.
The first EVA on the lunar surface was performed by Americans Neil Armstrong and Buzz Aldrin on July 21, 1969 (UTC), after the Apollo 11 Moon landing.
This first Moon walk lasted 2 hours, 36 minutes.
A total of fifteen Moon walks were performed by members of six Apollo crews, including Charles "Pete" Conrad, Alan Bean, Alan Shepard, Edgar Mitchell, David Scott, James Irwin, John Young, Charles Duke, Eugene "Gene" Cernan, and Dr. Harrison "Jack" Schmitt.
Cernan was the last Apollo astronaut to step off the surface of the Moon.
The first EVA in deep space was made on August 5, 1971, by American Al Worden, to retrieve a film and data recording canister from the Apollo 15 Service Module on the return trip from the Moon.
Worden was assisted by James Irwin, doing a standup EVA in the Command Module hatch.
This was repeated by Ken Mattingly and Charles Duke on Apollo 16 and by Ronald Evans and Harrison Schmitt on Apollo 17.
The first EVA repairs of a spacecraft were made by Charles "Pete" Conrad, Joseph Kerwin, and Paul J. Weitz on May 26, June 7, and June 19, 1973, on the Skylab 2 mission.
They rescued the functionality of the launch-damaged Skylab space station by freeing a stuck solar panel, deploying a solar heating shield, and freeing a stuck circuit breaker relay.
The Skylab 2 crew made three EVAs, and a total of ten EVAs were made by the three Skylab crews.
They found that activities in weightlessness required about 2 1/2 times the duration as on Earth because many astronauts suffered spacesickness early in their flights.
After Skylab, no more EVAs were made by the United States until the advent of the Space Shuttle program in the early 1980s.
In this period, the Soviets resumed EVAs, making four from the Salyut 6 and Salyut 7 space stations between December 20, 1977, and July 30, 1982.
When the United States resumed EVAs on April 7, 1983, astronauts started using an Extravehicular Mobility Unit (EMU) for self-contained life support independent of the spacecraft.
Also, for the first time, American astronauts used an airlock to enter and exit the spacecraft like the Soviets.
Accordingly, the American definition of EVA start time was redefined to when the astronaut switches the EMU to battery power. 
In 1985, Aldrin proposed the existence of a special spacecraft trajectory now known as the Aldrin cycler.
A spacecraft traveling on an Aldrin cycler trajectory would pass near the planets Earth and Mars on a regular (cyclic) basis.
The Aldrin cycler is an example of a Mars cycler.
He was also instrumental in the idea of training of astronauts underwater in order to better prepare them for the intricate space walks and duties of maintenance while in space. 
In the 1960s, the company was involved in a notable space age rivalry with Omega Watches to be selected as the 'first watch on the moon'.
Ultimately, Bulova either did not or could not certify the Accutron as dustproof.
The Omega Speedmaster Professional chronograph wristwatch (known as the "Moon watch") was designated by NASA for use by the astronauts in all manned space missions, becoming the first watch on the moon on the wrist of Buzz Aldrin.
All instrument panel clocks and time-keeping mechanisms in the spacecraft on those missions were Bulova Accutrons with tuning fork movements, because at the time, NASA did not know how well a mechanical movement would work in low gravity conditions.
An Accutron 214 movement was placed on the moon in a communications relay device by the first moon landing mission.
The U.S. government had used the 214 in military satellites, and had even prevailed on Bulova to delay the commercial release of the Accutron to prevent the Soviet Union from obtaining the technology during the Cold War.
The Bulova company briefly manufactured a limited edition "Astronaut" model under its Accutron line of watches.
The back of the watch case is autographed by Buzz Aldrin.
The tuning fork movement has been discontinued by Bulova, and the current Astronaut model features automatic ETA SA movement. 
In 2005, while being interviewed for a documentary titled "First on the Moon: The Untold Story", Aldrin told an interviewer that they saw an unidentified flying object.
Aldrin told David Morrison, a NASA Astrobiology Institute Senior Scientist, that the documentary cut the crew's conclusion that they were probably seeing one of four detached spacecraft adapter panels.
Their S-IVB upper stage was away, but the four panels were jettisoned before the S-IVB made its separation maneuver so they would closely follow the Apollo 11 spacecraft until its first midcourse correction.
When Aldrin appeared on "The Howard Stern Show" on August 15, 2007, Stern asked him about the supposed UFO sighting.
Aldrin confirmed that there was no such sighting of anything deemed extraterrestrial, and said they were and are "99.9 percent" sure that the object was the detached panel.
Interviewed by the Science Channel, Aldrin mentioned seeing unidentified objects, and according to Aldrin his words were taken out of context; he asked the Science Channel to clarify to viewers he did not see alien spacecraft, but they refused. 
Focused by the commitment to a moon landing, in January 1962 the US introduced Project Gemini, a two-crew-member spacecraft that would support Apollo by developing the key spaceflight technologies of space rendezvous and docking of two craft, flight durations of sufficient length to simulate going to the Moon and back, Extra-vehicular Activity for extended periods, and accomplishing useful work rather than just "walking in space."
Although Gemini took a year longer than planned to accomplish its first flight, Gemini took advantage of the USSR's two-year hiatus after Voskhod, which enabled the US to catch up and surpass the previous Soviet lead in piloted spaceflight.
Gemini achieved several significant firsts during the course of ten piloted missions:
 On Gemini 3 (March 1965), astronauts Virgil "Gus" Grissom and John W. Young became the first to demonstrate their ability to change their craft's orbit.
 On Gemini 5 (August 1965), astronauts L. Gordon Cooper and Charles "Pete" Conrad set a record of almost eight days in space, long enough for a piloted lunar mission.
 On Gemini 6A (December 1965), Command Pilot Wally Schirra achieved the first space rendezvous with Gemini 7, accurately matching his orbit to that of the other craft, station-keeping for three consecutive orbits at distances as close as .
 Gemini 7 also set a human spaceflight endurance record of fourteen days for Frank Borman and James A. Lovell, which stood until both nations started launching space laboratories in the early 1970s.
 On Gemini 8 (March 1966), Command Pilot Neil Armstrong achieved the first docking between two spacecraft, his Gemini craft and an Agena target vehicle.
 Gemini 11 (September 1966), commanded by Conrad, achieved the first direct-ascent rendezvous with its Agena target on the first orbit, and used the Agena's rocket to achieve an apogee of .
 On Gemini 12 (November 1966), Edwin E. "Buzz" Aldrin spent over five hours working comfortably during three (EVA) sessions, finally proving that humans could perform productive tasks outside their spacecraft.
(This proved to be the most difficult goal to achieve.
)
Most of the novice pilots on the early missions would command the later missions.
In this way, Project Gemini built up spaceflight experience for the pool of astronauts who would be chosen to fly the Apollo lunar missions.
