The flight plan called for Gemini XI to launch about 90 minutes after their Agena XI docking target vehicle and confirmation that the target had achieved its correct orbit. Conrad and Gordon would perform a direct ascent rendezvous profile, meaning approaching and docking their Gemini spacecraft with the Agena target on their very first orbit around the Earth. This maneuver simulated an Apollo Lunar Module lifting off from the surface and performing a rendezvous with the Command Module in lunar orbit. To successfully complete this so-called M=1 rendezvous, Gemini XI needed to liftoff within a two-second launch window. Conrad and Gordon would each practice two docking maneuvers to gain proficiency. On the second day, Gordon would perform his first spacewalk, a planned two-hour excursion during which he would attach a 100-foot tether between the Gemini and the Agena, and evaluate the Hand-Held Maneuvering Unit (HHMU) for translating between the two spacecraft. During the mission\u2019s third day, the astronauts would fire the Agena\u2019s main engine to raise the high-point of their orbit to a then-record 850 miles, and after two orbits, fire the engine again to return them to their original altitude. Gordon would then perform a two-hour standup spacewalk to conduct photography experiments. After undocking from the Agena, they planned to conduct experiments with the two spacecraft connected by the 100-foot tether. After a three-day mission, they would return to Earth, flying a completely automatic deorbit and reentry for a recovery in the Atlantic Ocean.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/09\/gemini_xi_5_gt11-211-noid-9.12.66.jpg\" alt=\"gemini xi\" width=\"219\" height=\"280\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/09\/gemini_xi_6_gt11-199-s66-50784-9.12.66.jpg\" alt=\"gemini xi\" width=\"144\" height=\"280\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/09\/gemini_xi_7_gt11-236a-s66-50730-9.12.66.jpg\" alt=\"gemini xi\" width=\"218\" height=\"280\"><br> <em>Left: Gemini XI astronauts Charles \u201cPete\u201d Conrad, left, and Richard F.

Conrad and Gordon boarded their Gemini spacecraft shortly before the Agena lifted off and achieved its proper orbit. Gemini XI successfully launched within its two-second launch window and began the chase to catch up with the Agena. As a team of controllers at the Mission Control Center at MSC led by Flight Director Glynn S. Lunney monitored the mission, Conrad and Gordon activated their spacecraft\u2019s radar and under computer direction, they completed a series of maneuvers to quickly reach the Agena. Just 85 minutes after launch, Conrad radioed to capsule communicator John W. Young, \u201cWould you believe M=1?\u201d indicating he had completed the world\u2019s first direct ascent rendezvous. Nine minutes later, he docked the two spacecraft. Conrad and Gordon then undocked and redocked three more times, giving both astronauts practice conducting the critical maneuver. After a busy first day, they began their first sleep period in space.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/09\/gemini_xi_8_carpenter_on_console_s66-51794.jpg\" alt=\"gemini xi carpenter on console\" width=\"293\" height=\"190\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/09\/gemini_xi_9_gt11-240-s66-52157-mission_control.jpg\" alt=\"gemini xi mission control\" width=\"294\" height=\"190\"><br> <em>Left: Astronaut M.

Struggling to fit his sun visor to his helmet while still inside the spacecraft, Gordon began the spacewalk already tired and overheated. After opening the hatch, he easily installed a handrail and retrieved a scientific experiment package from the outside of the spacecraft, but had some difficulty installing a camera. Once he accomplished that, Gordon attempted to jump from the Gemini to the Agena to retrieve the 100-foot tether, but he missed and ended up swinging back around on his own tether to the back of the Gemini. Conrad reeled him back toward the hatch, and on his second attempt Gordon reached the Agena and retrieved the tether and began connecting it to the front of the Gemini. In doing so, he straddled the Agena\u2019s docking collar, eliciting a \u201cRide \u2018em, cowboy!\u201d comment from Conrad. But the work proved more difficult than expected, and Gordon\u2019s suit couldn\u2019t keep up with his exertions. His right eye blinded by sweat, Gordon was exhausted. Concerned for his safety, Conrad told him to return to the spacecraft, ending the first spacewalk after just 38 minutes instead of the planned two hours. The HHMU evaluation and tests of a power drill could not be accomplished. Later in the day, the astronauts briefly opened the spacecraft\u2019s hatch to discard some unneeded equipment, freeing up space inside the cramped spacecraft. They spent the remainder of the day conducting experiments and taking photographs before going to sleep.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/09\/gemini_xi_12_eva1_gordon_returning_to_hatch_s66-54454-gordon_eva-9.13.66.jpg\" alt=\"gemini xi eva1 gordon returning to hatch\" width=\"341\" height=\"260\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/09\/gemini_xi_13_gordon_prior_to_hatch_open_to_jettison_equipment_s66-54590.jpg\" alt=\"gemini xi gordon prior to hatch open to jettison equipment\" width=\"260\" height=\"260\"><br> <em>Left: Gemini XI astronaut Richard F.

Conrad exuberantly called to the ground, \u201cWhoop-de-doo! [That\u2019s] the biggest thrill of my life!\u201d The 26-second burn raised the apogee, or orbital high point, of the docked spacecraft to 853 miles, breaking <a href=\"https:\/\/www.nasa.gov\/history\/55-years-ago-gemini-x-soars-to-new-heights\/\">Gemini X<\/a>\u2019s record and to this day the highest altitude attained during any non-lunar crewed mission. The astronauts took some spectacular photos when they reached that altitude flying over western Australia, the Earth\u2019s curvature more evident than from lower altitudes. Conrad and Gordon described the view as \u201cspectacular\u201d and \u201cfantastic.\u201d Two revolutions later, they fired the Agena\u2019s engine a second time to return to their previous lower altitude. Gordon then opened the hatch to conduct a 2-hour and 8-minute standup spacewalk, during which he stood in the spacecraft\u2019s open hatch conducting several science experiments and taking photographs. Following the spacewalk, Conrad and Gordon undocked from the Agena, with the 100-foot tether still connecting the two spacecraft. After a brief but unsuccessful attempt at achieving a gravity-gradient attitude, with the heavier Agena pointing toward the Earth, Conrad fired the Gemini\u2019s thrusters to initiate a slow 38-degree-per-minute spin of the two spacecraft around their common center of gravity. After increasing the rotation rate to 55 degrees per minute, they generated an artificial gravity field of about 0.00015 g, too weak for the astronauts to feel but enough that a camera released in the spacecraft drifted toward the rear of the cabin along the tether\u2019s axis. After three hours of tether operations, the astronauts jettisoned it from the Gemini spacecraft and backed away from the Agena. They began their last sleep period in space.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/09\/gemini_xi_14_western_australia_from_850_miles_up_s66-54706-b.jpg\" alt=\"western australia from 850 miles up\" width=\"265\" height=\"200\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/09\/gemini_xi_15_during_eva2_sep_14_1966_s66-54555.jpg\" alt=\"gemini xi during eva2 sep 14 1966\" width=\"200\" height=\"200\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/09\/gemini_xi_16_agena_on_tether_s66-54806.jpg\" alt=\"agena on tether\" width=\"209\" height=\"200\"><br> <em>Left: Western Australia as seen from Gemini XI at an altitude of 853 miles.

Conrad then fired the Gemini\u2019s thrusters to separate from the Agena for the last time. Three hours later, the spacecraft\u2019s autopilot directed the reentry burn. From then on, other than the crew jettisoning the spacecraft\u2019s equipment module, the guidance computer flew the remainder of the reentry through splashdown, automatically guiding Gemini XI to within two miles of the splashdown target in the Atlantic Ocean and less than three miles from the prime recovery ship U.S.S.
