Kennedy\u2019s goal of landing a man on the Moon and returning him safely to Earth before the end of the 1960s. Paramount among those techniques was rendezvous and docking, required to implement the Lunar Orbit Rendezvous method NASA chose for the Moon landing missions. Additional goals of Gemini included proving that astronauts could work outside their spacecraft during spacewalks and ensuring that spacecraft and astronauts could function for at least eight days, considered the minimum time for a roundtrip mission to the Moon. The first five Gemini missions in 1965 demonstrated the new spacecraft\u2019s space worthiness, the feasibility of <a href=\"https:\/\/www.nasa.gov\/history\/space-station-20th-spacewalking-history\/\">spacewalking<\/a>, extended flight durations to <a href=\"https:\/\/www.nasa.gov\/history\/55-years-ago-gemini-5-sets-a-new-record\/\">eight<\/a> and <a href=\"https:\/\/www.nasa.gov\/history\/55-years-ago-the-spirit-of-76-the-first-rendezvous-in-space\/\">14 days<\/a>, and demonstrated <a href=\"https:\/\/www.nasa.gov\/history\/55-years-ago-the-spirit-of-76-the-first-rendezvous-in-space\/\">space rendezvous<\/a> techniques. The goals of Gemini VIII, the first mission of 1966, included docking with a target vehicle and conducting a lengthy spacewalk during a three-day flight. The actual flight did demonstrate the first docking, but a stuck thruster resulted in an early emergency return.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" loading=\"lazy\" alt=\"gemini_viii_1_crew_photo\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/03\/gemini_viii_1_crew_photo_s65-58499.jpg\" width=\"297\" height=\"234\"> <img decoding=\"async\" loading=\"lazy\" alt=\"gemini_viii_2_crew_patch\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/03\/gemini_viii_2_crew_patch_s66-23978.jpg\" width=\"238\" height=\"238\"><br>\n<em>Left: Gemini VIII astronauts David R.

The flight plan called for Gemini VIII to launch about 90 minutes after their Agena target vehicle and confirmation that the target had achieved the correct orbit. Armstrong and Scott would begin the chase to catch up with the Agena, and less than seven hours after liftoff, Armstrong would guide Gemini VIII in for the world\u2019s first docking. The astronauts rehearsed the docking in a simulator at MSC.<\/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\/03\/gemini_viii_5_eva_backpack_s66-17475.jpg\" alt=\"gemini_viii_5_eva_backpack\" width=\"186\" height=\"262\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/03\/gemini_viii_6_scott_practicing_jet_pack_on_air_bearing_surface_s66-19284.jpg\" alt=\"gemini_viii_6_scott_practicing_jet_pack_on_air_bearing_surface\" width=\"181\" height=\"262\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/03\/gemini_viii_7_scott_eva_training_feb_18_1966_s66-21411.jpg\" alt=\"gemini_viii_7_scott_eva_training_feb_18_1966\" width=\"302\" height=\"262\"><br><\/p>\n\n\n\n<p class=\"has-text-align-center\"><em>Left: Engineer Fred R.

White\u2019s first brief excursion during Gemini IV the previous June.  Wearing a chest-mounted life support system as a backup to his 25-foot tether that provided primary life support and communications, Scott planned to perform a few simple tasks near the open hatch.  Next, Scott would translate to the rear of the spacecraft and back into a backpack support pack that included a 75-foot tether and a hand-held maneuvering unit. Meanwhile, Armstrong would undock the Gemini from the Agena and fly in formation 60 feet away. Using the maneuvering unit, Scott would translate to the end of his 75-foot tether. Armstrong flew the Gemini to retrieve him. Scott would reenter the spacecraft, ending the spacewalk, and Armstrong would redock with the Agena.  During their third day in space, the crew would perform two more undocking and redocking exercises and conduct a series of experiments before firing their retrorockets for the trip back to Earth. Splashdown was planned for the western Atlantic Ocean, with retrieval by the prime recovery ship, the helicopter landing ship U.S.S. Boxer (LPH-4), and the crew would fly back to KSC for debriefings. As for all crewed missions, recovery forces stood by at several backup splashdown locations in case the crew needed to make an emergency landing. <\/p>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" loading=\"lazy\" alt=\"gemini_viii_8_scott_armstrong_at_pad_mar_16_1966\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/03\/gemini_viii_8_scott_armstrong_at_pad_mar_16_1966_s66-24478.jpg\" width=\"190\" height=\"285\"> <img decoding=\"async\" loading=\"lazy\" alt=\"gemini_viii_9_agena_launch\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/03\/gemini_viii_9_agena_launch_s66-24482.jpg\" width=\"204\" height=\"285\"> <img decoding=\"async\" loading=\"lazy\" alt=\"gemini_viii_10_launch\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/03\/gemini_viii_10_launch_s66-18616.jpg\" width=\"131\" height=\"285\"><br>\n<em>Left: At the Cape Kennedy Air Force Station, now the Cape Canaveral<br>\nSpace Force Station in Florida, NASA astronauts David R.

At nearby Launch Pad 14, the Atlas rocket carrying the Agena target blasted off precisely on time and placed the target into its correct orbit. Gemini VIII took off on schedule and reached orbit six minutes later.  A team of controllers at the Mission Control Center (MCC) at MSC, led by Flight Director John D. Hodge, monitored the launch and the rendezvous. <a href=\"https:\/\/www.nasa.gov\/history\/55-years-ago-the-spirit-of-76-the-first-rendezvous-in-space\/\">Gemini VII<\/a> astronaut James A.

At a range of 206 miles, they established radar contact with their target and spotted it visually from 87 miles away, gleaming in the sunlight. Armstrong brought Gemini VIII within 150 feet of the Agena and maneuvered around the target as Scott visually inspected it. Then Armstrong brought the two spacecraft to within two feet of each other. Final checks complete, Armstrong received the call from the ground, \u201cGo ahead and dock.\u201d At a relative velocity of one foot per second, Armstrong brought Gemini VIII in for the final docking with the Agena, reporting to the ground, \u201cFlight, we are docked.\u201d After completing electrical connections between the two spacecraft, Scott commanded the Agena\u2019s thrusters to roll the combined vehicle 90 degrees, Armstrong telling Lovell that it had \u201cgone quite well.\u201d Passing out of communications range over the Indian Ocean, Armstrong and Scott noticed their spacecraft began an unexpected roll. Assuming a problem had occurred with the Agena, Scott turned off its thrusters while Armstrong reactivated the Gemini\u2019s to regain control over the spacecraft. The action worked temporarily, but the vehicle soon began unwanted motions in all three axes and at higher rates. Glancing at the instrument panel, Armstrong noticed the Gemini\u2019s fuel supply had dropped to 30%, and realized the problem was with their craft and not the Agena. Armstrong quickly undocked but, rid of the heavier Agena, the Gemini spacecraft began tumbling at much higher rates, reaching a roll rate of one rotation per second. Coming back into communications range, Scott reported to a stunned MCC, \u201cWe have serious problems here. We\u2019re tumbling end over end.\u201d To regain control of the spacecraft, the astronauts shut down the main thruster system and activated the re-entry system thrusters. With this action, they stabilized the spacecraft, but mission rules dictated that once they activated the re-entry system, they must land at the next available opportunity. Scott\u2019s ambitious spacewalk and the additional docking tests were cancelled. The post-mission analysis revealed that an electrical short circuit had caused thruster number 8 to stick in an open position, creating the wild gyrations and depleting the onboard fuel supply.<\/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\/03\/gemini_viii_13_agena_target_during_rendezvous_s66-25782.jpg\" alt=\"gemini_viii_13_agena_target_during_rendezvous\" width=\"222\" height=\"222\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/03\/gemini_viii_14_agena_target_approach_for_docking_s66-25784.jpg\" alt=\"gemini_viii_14_agena_target_approach_for_docking\" width=\"222\" height=\"222\"> <img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/03\/gemini_viii_15_agena_target_docked_s66-25785.jpg\" alt=\"gemini_viii_15_agena_target_docked\" width=\"222\" height=\"222\"><br><\/p>\n\n\n\n<p class=\"has-text-align-center\"><em>Left: The Gemini VIII astronauts inspect the Agena target vehicle from about 50 feet away.

Boxer, Gemini VIII now targeted a preplanned contingency area in the western Pacific Ocean 500 miles east of the Japanese island of Okinawa. A backup recovery ship, the destroyer U.S.S. Leonard P. Mason (DD-852), already assigned to the general area, immediately steamed toward the splashdown point. Aboard Gemini VIII, the disappointed astronauts fired their spacecraft\u2019s retrorockets in the darkness over south-central Africa. Following the fiery re-entry through the Earth\u2019s atmosphere, the Gemini capsule deployed its parachute and splashed down only 1.6 miles from its aim point after an abbreviated flight of 10 hours 41 minutes.

Accompanied by their wives Janet and Barbara, respectively, and MSC Deputy Director George M. Low, Armstrong, and Gordon visited 9 Latin American countries (Colombia, Brazil, Ecuador, Peru, Bolivia, Uruguay, Argentina, Chile, and Panama) between Oct. 7-31, 1966. <\/p>\n\n\n\n<p>The Gemini X crew of John W. Young and Michael Collins revisited Gemini VIII\u2019s Agena target in July 1966 but did not dock with it, making a passive rendezvous with the inactive spacecraft. They found it stable and in good condition. Using a hand-held maneuvering unit during a spacewalk, Collins flew from the Gemini X spacecraft to the inert Agena and retrieved a micrometeorite collector panel from its exterior, completing a task unfinished by the Gemini VIII crew. The Agena VIII target spacecraft <a href=\"https:\/\/www.nasa.gov\/history\/50th-anniversary-of-final-gemini-hardware-reentry\/\">reentered the Earth\u2019s atmosphere<\/a> on Sep. 15, 1967, the last piece of Gemini Program hardware to leave orbit. The Gemini VIII spacecraft is on display at the Neil Armstrong Air and Space Museum in Wapakoneta, Ohio.<\/p>\n\n\n\n<p>Although Armstrong and Scott distinguished themselves during the in-flight emergency, NASA didn\u2019t assign an all-rookie crew to a spaceflight again until the <a href=\"https:\/\/www.nasa.gov\/history\/45-years-ago-splashdown-of-third-and-final-skylab-crew\/\">Skylab-4<\/a> mission in 1973.

They were the only Gemini crew whose both members walked on the Moon.<\/p>\n\n\n<div id=\"\" class=\"nasa-gb-align-full width-full maxw-full padding-x-3 padding-y-0 article_a hds-module hds-module-full wp-block-nasa-blocks-credits-and-details\">\n<section class=\"padding-x-0 padding-top-5 padding-bottom-2 desktop:padding-top-7 desktop:padding-bottom-9\">\n\t<div class=\"grid-row grid-container maxw-widescreen padding-0\">\n\t\t<div class=\"grid-col-12 desktop:grid-col-2 padding-right-4 margin-bottom-5 desktop:margin-bottom-0\">\n\t\t\t<div class=\"padding-top-3 border-top-1px border-color-carbon-black\">\n\t\t\t\t<div class=\"margin-bottom-2\">\n\t\t\t\t\t<h2 class=\"heading-14\">Share<\/h2>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"padding-bottom-2\">\n\t\t\t\t\t<ul class=\"social-icons social-icons-round\">\n\t\t\t\t\t\t<li class=\"social-icon social-icon-x\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/x.com\/intent\/tweet?via=NASA&text=55%20Years%20Ago%3A%20Gemini%20VIII%2C%20the%20First%20Docking%20in%20Space&url=https%3A%2F%2Fwww.nasa.gov%2Fhistory%2F55-years-ago-gemini-viii-the-first-docking-in-space%2F\" aria-label=\"Share on X.\">\n\t\t\t\t\t\t\t\t<svg width=\"1200\" height=\"1227\" viewBox=\"0 0 1200 1227\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M714.163 519.284L1160.89 0H1055.03L667.137 450.887L357.328 0H0L468.492 681.821L0 1226.37H105.866L515.491 750.218L842.672 1226.37H1200L714.137 519.284H714.163ZM569.165 687.828L521.697 619.934L144.011 79.6944H306.615L611.412 515.685L658.88 583.579L1055.08 1150.3H892.476L569.165 687.854V687.828Z\" fill=\"white\"\/><\/svg>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t<li class=\"social-icon social-icon-facebook\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.facebook.com\/sharer.php?u=https%3A%2F%2Fwww.nasa.gov%2Fhistory%2F55-years-ago-gemini-viii-the-first-docking-in-space%2F\" aria-label=\"Share on Facebook.\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 24 24\" aria-hidden=\"true\"><path d=\"M9 8h-3v4h3v12h5v-12h3.642l.358-4h-4v-1.667c0-.955.192-1.333 1.115-1.333h2.885v-5h-3.808c-3.596 0-5.192 1.583-5.192 4.615v3.385z\"\/><\/svg>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t<li class=\"social-icon social-icon-linkedin\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.linkedin.com\/shareArticle?mini=true&url=https%3A%2F%2Fwww.nasa.gov%2Fhistory%2F55-years-ago-gemini-viii-the-first-docking-in-space%2F\" aria-label=\"Share on LinkedIn.\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 24 24\" aria-hidden=\"true\"><path d=\"M4.98 3.5c0 1.381-1.11 2.5-2.48 2.5s-2.48-1.119-2.48-2.5c0-1.38 1.11-2.5 2.48-2.5s2.48 1.12 2.48 2.5zm.02 4.5h-5v16h5v-16zm7.982 0h-4.968v16h4.969v-8.399c0-4.67 6.029-5.052 6.029 0v8.399h4.988v-10.131c0-7.88-8.922-7.593-11.018-3.714v-2.155z\"\/><\/svg>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t<li class=\"social-icon social-icon-rss\">\n\t\t\t\t\t\t\t<a href=\"\/feed\/\" aria-label=\"Subscribe to RSS feed.\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 800 800\" aria-hidden=\"true\"><path d=\"M493 652H392c0-134-111-244-244-244V307c189 0 345 156 345 345zm71 0c0-228-188-416-416-416V132c285 0 520 235 520 520z\"\/><circle cx=\"219\" cy=\"581\" r=\"71\"\/><\/svg>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n\t\t\t\t\t<\/ul>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t<div class=\"grid-col-12 desktop:grid-col-5 padding-right-4 margin-bottom-5 desktop:margin-bottom-0\">\n\t\t\t<div class=\"padding-top-3 border-top-1px border-color-carbon-black\">\n\t\t\t\t<div class=\"margin-bottom-2\">\n\t\t\t\t\t<h2 class=\"heading-14\">Details<\/h2>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"grid-row margin-bottom-3\">\n\t\t\t\t\t<div class=\"grid-col-4\">\n\t\t\t\t\t\t<div class=\"subheading\">Last Updated<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div class=\"grid-col-8\">Sep 22, 2023<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t<div class=\"grid-col-12 desktop:grid-col-5 padding-right-4 margin-bottom-5 desktop:margin-bottom-0\"><div class=\"padding-top-3 border-top-1px border-color-carbon-black \"><div class=\"margin-bottom-2\"><h2 class=\"heading-14\">Related Terms<\/h2><\/div><ul class=\"article-tags\"><li class=\"article-tag\"><a href=\"https:\/\/www.nasa.gov\/history\/\">NASA History<\/a><\/li><li class=\"article-tag\"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2016\/01\/scott_david.pdf?emrc=54adfb\">David R.
