→Gemini 8 (officially Gemini VIII) was the sixth crewed spaceflight in 's program, launched March 16, 1966. It was the twelfth crewed American flight and the twenty-second crewed spaceflight of all time including two flights higher than the at 100 kilometers (54 nautical miles; 62 miles; 328,084 feet). The mission conducted the first docking of two spacecraft in orbit, but 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 was returned to Earth safely.Command pilot 's flight marked the second time a U.S. Civilian flew into space ( became the first on ), and the first time a U.S.

Undocked: 22:45 UTCObjectives Gemini VIII was planned to be a three-day mission. After being launched into an 87-by-146-nautical-mile (161 by 270 km) orbit, on the fourth revolution it was to and with an, which had been earlier launched into a 161-nautical-mile (298 km) circular orbit.
This was to be the first space docking in history. Four separate dockings were planned.During the first docking, Pilot David Scott planned to perform an ambitious, two-hour-and-10-minute (EVA), which would have been the first since 's June 1965 spacewalk on. On a 25-foot (7.6 m) tether for one and a half revolutions around the Earth, Scott would have retrieved a nuclear emulsion radiation experiment from the front of the Gemini's spacecraft adapter, then activate a experiment on the Agena.
Then he was to move back to the Gemini and test a minimum-reaction power tool by loosening and tightening bolts on a work panel.During the EVA, after Armstrong undocked from the Agena, Scott was to don and test an Extravehicular Support Pack (ESP) stored at the back of the spacecraft adapter. This was a backpack with a self-contained oxygen supply, extra propellant for his Hand Held Maneuvering Unit, and a 75-foot (23 m) extension to his tether. He would practice several maneuvers in formation with the Gemini and Agena vehicles (separated at distances up to 60 feet (18 m), in concert with Armstrong in the Gemini. Scott never got to perform this EVA, due to the abort of the flight because of an emergency which occurred shortly after docking.The flight also carried an additional three scientific, four technological, and one medical experiment.
Flight Agena Target Vehicle Five months earlier, NASA had launched an for, but the launch failed when the Agena's engine exploded during orbital injection and the mission had to be rescheduled. The next attempt succeeded.
Everything worked perfectly; the Agena put itself into a 298 kilometer circular and oriented itself to the correct attitude for the docking. The Gemini spacecraft itself was launched into a 160 by 272 kilometer orbit by a modified on March 16, 1966 (coincidentally the 40th anniversary of the launch of the world's first liquid-fueled rocket by Dr. ), at 10:41:02 a.m. Gemini 8's launch was nominal and no significant anomalies occurred with either the Titan II or the spacecraft. The Agena Target Vehicle as seen from Gemini 8 during rendezvous.Their first course adjustment was made at one hour and 34 minutes into the mission, when the astronauts lowered their apogee slightly with a five-second (OAMS) thruster burn. The second adjustment was made near apogee of the second orbit, and raised both the apogee and perigee by adding 49 feet per second (15 m/s) to their speed.
The third adjustment was made over the Pacific Ocean, a southward orbital plane change, made with a 59 feet per second (18 m/s) sideways thruster burn. When they were over Mexico, the Houston, told them they needed one last correction, a 2.6 feet per second (0.79 m/s) speed addition.The rendezvous radar acquired the Agena Target Vehicle at a distance of 179 nautical miles (332 km).
At 3 hours, 48 minutes and 10 seconds into the mission they performed another burn that put them in a circular orbit 15 nautical miles (28 km) below the Agena. They first sighted it when they were 76 nautical miles (141 km) away, and at 55 nautical miles (102 km) they gave the computer automatic control.After several small burns they were 151 feet (46 m) away and with no relative velocity.
After 30 minutes of visually inspecting the Agena to make sure that it had not been damaged by the launch, they were given the go for docking. Armstrong started to move towards the Agena at 3.15 inches (8 centimeters) per second. In a matter of minutes, the Agena's docking latches clicked and a green light indicated that the docking had been successfully completed. 'Flight, we are docked! Yes, it's really a smoothie,' Scott radioed to the ground.Emergency There was some suspicion on the ground that the Agena's system was malfunctioning and might not have the correct program stored in it. This suspicion was found to be incorrect. Shortly before radio blackout, cautioned the astronauts to immediately abort the docking if any abnormalities occurred with the Agena.After the Agena began execution of its stored command program, which instructed the Agena to turn the combined spacecraft 90° to the right, Scott noticed that they were rolling.
Armstrong used the Gemini's OAMS thrusters to stop the roll, but after it stopped, it immediately started again. Gemini 8 was out of range of ground communications at this time. Location of Gemini OAMS and Reentry (mislabeled 'Reaction') Control System thrustersArmstrong reported that the OAMS fuel had dropped to 30%, indicating that the problem could be on their own spacecraft. With concern that the high rate of rotation might damage one or both spacecraft or even cause the propellant-heavy Agena to rupture or explode, the crew decided to undock from the Agena so they could analyze the situation. Scott switched the Agena control back to ground command, while Armstrong struggled to stabilize the combined vehicle enough to permit undocking.
Scott then hit the undock button, and Armstrong fired a long burst of translation thrusters to back away from the Agena. Without the added mass of the Agena, Gemini started rotating more rapidly.The astronauts realized that the problem was on the Gemini.
By now the tumble rate had reached 296 degrees per second and Armstrong decided to shut down the OAMS and use the Reentry Control System (RCS) thrusters, located on the Gemini's nose, to stop the tumble. Scott later praised Armstrong's actions as their spacecraft spun: 'The guy was brilliant. He knew the system so well. He found the solution, he activated the solution, under extreme circumstances.
It was my lucky day to be flying with him.' The spacecraft came in range of the ground communications ship. After steadying the spacecraft, the crew tested each OAMS thruster in turn and found that Number 8 had stuck on. Almost 75% of the reentry maneuvering fuel had been used to stop the tumble, and mission rules dictated that the flight be aborted once the Reentry Control System was fired for any reason. Gemini 8 immediately prepared for an emergency landing.Landing and recovery.
Scott (L) and Armstrong (R) await USS Leonard F. MasonIt was decided to let the spacecraft reenter one orbit later so that it could land in a place that could be reached by the secondary recovery forces. The original plan was for Gemini 8 to land in the Atlantic, but that was supposed to be three days later. Started to steam towards the new landing site 800 kilometers (430 nmi; 500 mi) east of and 1,000 kilometers (540 nmi; 620 mi) south of,.Reentry took place over China, out of range of NASA tracking stations.Planes were also dispatched, and pilot spotted the spacecraft as it descended precisely on time and on target. Three pararescuers jumped from their and attached a flotation collar to the capsule.
The three pararescuers were A/2C Glenn M. Moore; A/1C Eldridge M. Neal; and S/Sgt Larry D. Huyett.All of the pararescuers and astronauts suffered from seasickness.
Three hours after, Leonard F. Mason, which had been outfitted with quarantine equipment, had both the men and the spacecraft on board.
The astronauts were exhausted, but had otherwise survived the flight and their time on the water in good condition. They were briefly checked and slept for nine hours.The next morning, the ship docked at the port of. Fellow Astronaut and other NASA officials flew in to greet them before the astronauts were summoned back to the ship for medical tests and debriefing. After release, they were brought by limousine to waiting helicopters where they flew to and then on to Florida on a.Upon the return, the spacecraft was covered with a tarp.
As part of the investigation into the mishap, ground controllers tested the Agena stage for the next several days by ordering it to perform various in-orbit maneuvers until exhausting its propellant and electrical power.Four months later, the crew of rendezvoused with the inert Agena and astronaut retrieved its micrometeorite collector.Cause and outcome No conclusive reason for the thruster malfunction was found. The most probable cause was determined to be an electrical short, most likely due to a discharge. Power still flowed to the thruster, even when it was switched off. To prevent recurrence of this problem, spacecraft designs were changed so each thruster would have an isolated circuit. The Gemini 8 crews answer questions at an MSC press conference.The Deputy Administrator of NASA, was attending a celebratory dinner sponsored by the, at which Vice President was the guest speaker, when the problem arose. The incident inspired Seamans to review NASA's problem investigation procedures, modeled after military crash investigations, and on April 14, 1966, to formalize a new procedure in Management Instruction 8621.1, Mission Failure Investigation Policy And Procedures.
This gave the Deputy Administrator the option of performing independent investigations of major failures, beyond those failure investigations for which the various Program Office officials were normally responsible. It declared: 'It is NASA policy to investigate and document the causes of all major mission failures which occur in the conduct of its space and aeronautical activities and to take appropriate corrective actions as a result of the findings and recommendations.' Seamans first invoked this new procedure immediately following the fatal spacecraft fire on January 27, 1967. It was also invoked after the next critical in-flight failure, which occurred on the lunar mission in April 1970., the Gemini spacecraft prime contractor, also changed its procedures.
Prior to the accident, McDonnell's top engineers would be at for the launch, then fly to in for the rest of the mission. The problem occurred while they were en route, so it was decided to keep McDonnell engineers in Houston for the entire mission. Insignia.

When they were over Mexico, the Houston, told them they needed one last correction, a 2.6 feet per second (0.79 m/s) speed addition.The rendezvous radar acquired the Agena Target Vehicle at a distance of 179 nautical miles (332 km).
At 3 hours, 48 minutes and 10 seconds into the mission they performed another burn that put them in a circular orbit 15 nautical miles (28 km) below the Agena. They first sighted it when they were 76 nautical miles (141 km) away, and at 55 nautical miles (102 km) they gave the computer automatic control.After several small burns they were 151 feet (46 m) away and with no relative velocity.
After 30 minutes of visually inspecting the Agena to make sure that it had not been damaged by the launch, they were given the go for docking. Armstrong started to move towards the Agena at 3.15 inches (8 centimeters) per second. In a matter of minutes, the Agena\'s docking latches clicked and a green light indicated that the docking had been successfully completed. \'Flight, we are docked! Yes, it\'s really a smoothie,\' Scott radioed to the ground.Emergency There was some suspicion on the ground that the Agena\'s system was malfunctioning and might not have the correct program stored in it. This suspicion was found to be incorrect. Shortly before radio blackout, cautioned the astronauts to immediately abort the docking if any abnormalities occurred with the Agena.After the Agena began execution of its stored command program, which instructed the Agena to turn the combined spacecraft 90° to the right, Scott noticed that they were rolling.
Armstrong used the Gemini\'s OAMS thrusters to stop the roll, but after it stopped, it immediately started again. Gemini 8 was out of range of ground communications at this time. Location of Gemini OAMS and Reentry (mislabeled \'Reaction\') Control System thrustersArmstrong reported that the OAMS fuel had dropped to 30%, indicating that the problem could be on their own spacecraft. With concern that the high rate of rotation might damage one or both spacecraft or even cause the propellant-heavy Agena to rupture or explode, the crew decided to undock from the Agena so they could analyze the situation. Scott switched the Agena control back to ground command, while Armstrong struggled to stabilize the combined vehicle enough to permit undocking.
Scott then hit the undock button, and Armstrong fired a long burst of translation thrusters to back away from the Agena. Without the added mass of the Agena, Gemini started rotating more rapidly.The astronauts realized that the problem was on the Gemini.
By now the tumble rate had reached 296 degrees per second and Armstrong decided to shut down the OAMS and use the Reentry Control System (RCS) thrusters, located on the Gemini\'s nose, to stop the tumble. Scott later praised Armstrong\'s actions as their spacecraft spun: \'The guy was brilliant. He knew the system so well. He found the solution, he activated the solution, under extreme circumstances.
It was my lucky day to be flying with him.\' The spacecraft came in range of the ground communications ship. After steadying the spacecraft, the crew tested each OAMS thruster in turn and found that Number 8 had stuck on. Almost 75% of the reentry maneuvering fuel had been used to stop the tumble, and mission rules dictated that the flight be aborted once the Reentry Control System was fired for any reason. Gemini 8 immediately prepared for an emergency landing.Landing and recovery.
Scott (L) and Armstrong (R) await USS Leonard F. MasonIt was decided to let the spacecraft reenter one orbit later so that it could land in a place that could be reached by the secondary recovery forces. The original plan was for Gemini 8 to land in the Atlantic, but that was supposed to be three days later. Started to steam towards the new landing site 800 kilometers (430 nmi; 500 mi) east of and 1,000 kilometers (540 nmi; 620 mi) south of,.Reentry took place over China, out of range of NASA tracking stations.Planes were also dispatched, and pilot spotted the spacecraft as it descended precisely on time and on target. Three pararescuers jumped from their and attached a flotation collar to the capsule.
The three pararescuers were A/2C Glenn M. Moore; A/1C Eldridge M. Neal; and S/Sgt Larry D. Huyett.All of the pararescuers and astronauts suffered from seasickness.
Three hours after, Leonard F. Mason, which had been outfitted with quarantine equipment, had both the men and the spacecraft on board.
The astronauts were exhausted, but had otherwise survived the flight and their time on the water in good condition. They were briefly checked and slept for nine hours.The next morning, the ship docked at the port of. Fellow Astronaut and other NASA officials flew in to greet them before the astronauts were summoned back to the ship for medical tests and debriefing. After release, they were brought by limousine to waiting helicopters where they flew to and then on to Florida on a.Upon the return, the spacecraft was covered with a tarp.
As part of the investigation into the mishap, ground controllers tested the Agena stage for the next several days by ordering it to perform various in-orbit maneuvers until exhausting its propellant and electrical power.Four months later, the crew of rendezvoused with the inert Agena and astronaut retrieved its micrometeorite collector.Cause and outcome No conclusive reason for the thruster malfunction was found. The most probable cause was determined to be an electrical short, most likely due to a discharge. Power still flowed to the thruster, even when it was switched off. To prevent recurrence of this problem, spacecraft designs were changed so each thruster would have an isolated circuit. The Gemini 8 crews answer questions at an MSC press conference.The Deputy Administrator of NASA, was attending a celebratory dinner sponsored by the, at which Vice President was the guest speaker, when the problem arose. The incident inspired Seamans to review NASA\'s problem investigation procedures, modeled after military crash investigations, and on April 14, 1966, to formalize a new procedure in Management Instruction 8621.1, Mission Failure Investigation Policy And Procedures.
This gave the Deputy Administrator the option of performing independent investigations of major failures, beyond those failure investigations for which the various Program Office officials were normally responsible. It declared: \'It is NASA policy to investigate and document the causes of all major mission failures which occur in the conduct of its space and aeronautical activities and to take appropriate corrective actions as a result of the findings and recommendations.\' Seamans first invoked this new procedure immediately following the fatal spacecraft fire on January 27, 1967. It was also invoked after the next critical in-flight failure, which occurred on the lunar mission in April 1970., the Gemini spacecraft prime contractor, also changed its procedures.
Prior to the accident, McDonnell\'s top engineers would be at for the launch, then fly to in for the rest of the mission. The problem occurred while they were en route, so it was decided to keep McDonnell engineers in Houston for the entire mission. Insignia.
