The eight-day Gemini V endurance mission doubled America\u2019s spaceflight record set two months earlier. It also tested technology that would help make longer missions possible in the future.<\/p>\n\n\n\n<p>One of the lasting benefits of NASA\u2019s Gemini Program was its sustained technological investments accumulated over a two-year period. These new capabilities allowed astronauts not only to meet the challenges for landing on the moon, but laid the groundwork for long-duration missions aboard the International Space Station and future flights to destinations that still await, such as a near-Earth asteroid and Mars.<\/p>\n\n\n\n<p>Now, 50 years after Gemini V, NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko are in the midst of a one-year stay in orbit aboard the space station. With the doubling of the length of the usual ISS stay, researchers hope to better understand how the human body reacts and adapts to longer-duration spaceflight. This knowledge is crucial as NASA looks toward human journeys to and from Mars, which could last 500 days or longer.<\/p>\n\n\n\n<p>In addition to efforts to determine microgravity\u2019s effects after more than a week in orbit, the crew of Gordon Cooper and first-time astronaut Charles \u201cPete\u201d Conrad planned to attempt to catch up with an instrument package called the rendezvous evaluation pod (REP).<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-cover \"><a href=\"https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=1904&h=1920&fit=clip&crop=faces%2Cfocalpoint\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1904\" height=\"1920\" src=\"https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=1904&h=1920&fit=clip&crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Astronauts Pete Conrad and Gordon Cooper, the prime crew for Gemini-Titan 5, pose for a photo in white spacesuits\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=1904&h=1920&fit=crop&crop=faces%2Cfocalpoint 1904w, https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=150&h=151&fit=crop&crop=faces%2Cfocalpoint 150w, https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=298&h=301&fit=crop&crop=faces%2Cfocalpoint 298w, https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=768&h=774&fit=crop&crop=faces%2Cfocalpoint 768w, https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=1016&h=1025&fit=crop&crop=faces%2Cfocalpoint 1016w, https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=1524&h=1537&fit=crop&crop=faces%2Cfocalpoint 1524w, https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=50&h=50&fit=crop&crop=faces%2Cfocalpoint 50w, https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=100&h=101&fit=crop&crop=faces%2Cfocalpoint 100w, https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=397&h=400&fit=crop&crop=faces%2Cfocalpoint 397w, https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=595&h=600&fit=crop&crop=faces%2Cfocalpoint 595w, https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=893&h=901&fit=crop&crop=faces%2Cfocalpoint 893w, https:\/\/images-assets.nasa.gov\/image\/S65-46990\/S65-46990~large.jpg?w=1190&h=1200&fit=crop&crop=faces%2Cfocalpoint 1190w\" sizes=\"(max-width: 1904px) 100vw, 1904px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">S65-46990 (16 Aug. 1965) — Astronauts Charles Conrad Jr. (left), pilot, and L.

Conrad was a member of the agency\u2019s second group of astronauts. He would go on to command Gemini 11 in 1966, walk on the moon during Apollo 12 in 1969 and lead the first Skylab crew in May and June 1973.<\/p>\n\n\n\n<p>As flights became longer and more complex, the NASA team at the Kennedy Space Center and Cape Kennedy (now Cape Canaveral) Air Force Station intensified its efforts to ensure mission success. The Florida spaceport\u2019s NASA test conductor for Gemini V was Chuck Gay. He and a team of specialists conducted nine weeks of capsule factory tests and inspections at the McDonnell Aircraft Corp. in St. Louis where the spacecraft was built. The capsule then was flown to Kennedy for another eight weeks of prelaunch checkouts.<\/p>\n\n\n\n<p>\u201cA great deal of knowledge was gained during the four previous Gemini missions, particularly the two manned flights,\u201d Gay said in a 1965 interview<em>.<\/em> \u201cExtremely rigid specifications were tightened even further for Gemini 5, and inspection procedures were more stringent than those previously used.\u201d<\/p>\n\n\n\n<p>He noted that the scrutiny was due to the new, untested procedures planned for the upcoming flight.<\/p>\n\n\n\n<p>\u201cGemini V will demonstrate an eight-day long-duration capability for both the spacecraft and crew,\u201d he said. \u201cIn addition, this will be the first use of fuel cells for supplying spacecraft power during a manned flight.\u201d<\/p>\n\n\n\n<p>A fuel cell converts energy from a fuel, such as liquid hydrogen, into electricity through a chemical reaction with liquid oxygen or another oxidizing agent. By comparison, a battery stores the chemical reactants. Once used up, a battery must be recharged or discarded. A fuel cell will continue to produce electricity as long as it has a fuel supply, a crucial technology for long-duration spaceflights.<\/p>\n\n\n\n<p>Gemini V astronauts Cooper and Conrad also were the first to design an insignia patch for their flight. The original version featured a Conestoga covered wagon, noting the pioneering effort of Gemini. On the side was the slogan \u201c8 Days or Bust.\u201d<\/p>\n\n\n\n<p>After the design was submitted for review to NASA Administrator James Webb, he wrote Director of Flight Crew Operations Deke Slayton, approving the concept but expressing reservations about the slogan.<\/p>\n\n\n\n<p>\u201cI have a very strong concern about the \u20188 days or bust\u2019 motto,\u201d he said in the Aug. 14, 1965, memo. \u201cI wish it could be omitted. If the flight does not go eight days, there are many who are going to say it was \u2018busted.’\u201d<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2015\/08\/gemini_5_patches-1.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1267\" height=\"634\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2015\/08\/gemini_5_patches-1.jpg?w=1267\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Gemini V Mission Patch\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2015\/08\/gemini_5_patches-1.jpg 1267w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2015\/08\/gemini_5_patches-1.jpg?resize=300,150 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2015\/08\/gemini_5_patches-1.jpg?resize=768,384 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2015\/08\/gemini_5_patches-1.jpg?resize=1024,512 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2015\/08\/gemini_5_patches-1.jpg?resize=400,200 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2015\/08\/gemini_5_patches-1.jpg?resize=600,300 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2015\/08\/gemini_5_patches-1.jpg?resize=900,450 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2015\/08\/gemini_5_patches-1.jpg?resize=1200,600 1200w\" sizes=\"(max-width: 1267px) 100vw, 1267px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">Gemini V was the first mission to have a crew insignia.

They were relieved when the fuel cells were restarted and tested by using equipment that required more and more power. This showed that the fuel cell pressure remained stable and the crew could continue its mission.<\/p>\n\n\n\n<p>In the meantime, fellow astronaut Buzz Aldrin developed an alternative rendezvous test since the REP was no longer available. His astronautics doctoral thesis from the Massachusetts Institute of Technology was \u201cGuidance for Manned Orbital Rendezvous.\u201d Aldrin worked out a plan in which the crew could rendezvous with a \u201cpoint in space.\u201d It went perfectly, and marked the first-ever precision maneuvers on a spaceflight.<\/p>\n\n\n\n<p>The Gemini V crew went to work on other experiments planned for the mission, including high-resolution photography, medical experiments similar to those performed on Gemini IV, as well as an experiment into the performance of the human heart in microgravity.<\/p>\n\n\n\n<p>Cooper and Conrad returned to Earth on Aug. 29, 1965. They controlled their re-entry, creating drag and lift by rotating the capsule. Even so, the crew splashed down in the Atlantic Ocean about 80 miles short of the planned landing point due to a computing error. A helicopter from the recovery ship, USS Lake Champlain, soon picked up the Gemini V crew and took them to the aircraft carrier.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=1919&h=1919&fit=clip&crop=faces%2Cfocalpoint\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1919\" height=\"1919\" src=\"https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=1919&h=1919&fit=clip&crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Pete Conrad and Gordon Cooper celebrate their successful Gemini 5 spaceflight on their recovery ship\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=1919&h=1919&fit=crop&crop=faces%2Cfocalpoint 1919w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=150&h=150&fit=crop&crop=faces%2Cfocalpoint 150w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=300&h=300&fit=crop&crop=faces%2Cfocalpoint 300w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=768&h=768&fit=crop&crop=faces%2Cfocalpoint 768w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=1024&h=1024&fit=crop&crop=faces%2Cfocalpoint 1024w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=1536&h=1536&fit=crop&crop=faces%2Cfocalpoint 1536w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=50&h=50&fit=crop&crop=faces%2Cfocalpoint 50w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=100&h=100&fit=crop&crop=faces%2Cfocalpoint 100w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=200&h=200&fit=crop&crop=faces%2Cfocalpoint 200w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=400&h=400&fit=crop&crop=faces%2Cfocalpoint 400w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=600&h=600&fit=crop&crop=faces%2Cfocalpoint 600w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=900&h=900&fit=crop&crop=faces%2Cfocalpoint 900w, https:\/\/images-assets.nasa.gov\/image\/s65-46638\/s65-46638~large.jpg?w=1200&h=1200&fit=crop&crop=faces%2Cfocalpoint 1200w\" sizes=\"(max-width: 1919px) 100vw, 1919px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">S65-46638 (29 Aug. 1965) — Astronaut Charles Conrad Jr. tweaks astronaut L.
