During June 1965, two astronauts would not only stay in orbit four days, one would attempt America’s first spacewalk. It was another example of advancing technology enabling new avenues of exploration.<\/p>\n\n\n\n<p>Since the Soviet Union launched the world’s first satellite, Sputnik 1, in Oct. 4, 1957, the United States had been attempting to catch up in the space race. The Russians passed the Americans again on March 18, 1965, when cosmonaut Alexei Leonov performed the first spacewalk during the one-day Voskhod 2 mission. However, with Gemini IV, NASA was quickly catching up.<\/p>\n\n\n\n<p>Air Force pilots <a href=\"https:\/\/www.nasa.gov\/news-release\/correction-apollo-astronaut-james-mcdivitt-dies-at-age-93\/\" data-type=\"press-release\" data-id=\"142623\">Jim McDivitt<\/a> and <a href=\"https:\/\/www.nasa.gov\/former-astronaut-edward-h-white-ii\/\" data-type=\"topic\" data-id=\"258532\">Ed White<\/a> were selected as the crew for the upcoming flight. Like John Young on Gemini III, they were members of the agency’s second group of astronauts. McDivitt went on to command Apollo 9, the first piloted test of the lunar module, and he later became manager of Lunar Landing Operations and Apollo Spacecraft Program manager.<\/p>\n\n\n\n<p>During Gemini IV, White would become the first American to venture outside his spacecraft for what is officially known as an extravehicular activity, or EVA. The world has come to know it as a spacewalk. In the following years, it was a skill that allowed Apollo explorers to walk on the moon and American astronauts and their partners from around the world to build the International Space Station.<\/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\/S65-19528\/S65-19528~large.jpg?w=1539&h=1920&fit=clip&crop=faces%2Cfocalpoint\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1539\" height=\"1920\" src=\"https:\/\/images-assets.nasa.gov\/image\/S65-19528\/S65-19528~large.jpg?w=1539&h=1920&fit=clip&crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Portrait of Ed White and Jim McDivitt suited up in their space suits.\" style=\"transform: scale(1); transform-origin: 47% 76%; object-position: 47% 76%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/images-assets.nasa.gov\/image\/S65-19528\/S65-19528~large.jpg?w=1539&h=1920&fit=crop&crop=faces%2Cfocalpoint 1539w, https:\/\/images-assets.nasa.gov\/image\/S65-19528\/S65-19528~large.jpg?w=240&h=299&fit=crop&crop=faces%2Cfocalpoint 240w, https:\/\/images-assets.nasa.gov\/image\/S65-19528\/S65-19528~large.jpg?w=768&h=958&fit=crop&crop=faces%2Cfocalpoint 768w, https:\/\/images-assets.nasa.gov\/image\/S65-19528\/S65-19528~large.jpg?w=821&h=1024&fit=crop&crop=faces%2Cfocalpoint 821w, https:\/\/images-assets.nasa.gov\/image\/S65-19528\/S65-19528~large.jpg?w=1231&h=1536&fit=crop&crop=faces%2Cfocalpoint 1231w, https:\/\/images-assets.nasa.gov\/image\/S65-19528\/S65-19528~large.jpg?w=321&h=400&fit=crop&crop=faces%2Cfocalpoint 321w, https:\/\/images-assets.nasa.gov\/image\/S65-19528\/S65-19528~large.jpg?w=481&h=600&fit=crop&crop=faces%2Cfocalpoint 481w, https:\/\/images-assets.nasa.gov\/image\/S65-19528\/S65-19528~large.jpg?w=721&h=899&fit=crop&crop=faces%2Cfocalpoint 721w, https:\/\/images-assets.nasa.gov\/image\/S65-19528\/S65-19528~large.jpg?w=962&h=1200&fit=crop&crop=faces%2Cfocalpoint 962w\" sizes=\"(max-width: 1539px) 100vw, 1539px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">Gemini IV astronauts Ed White, left, and Jim McDivitt, pose at Cape Kennedy’s Launch Pad 19 on June 1, 1965.<\/div><div class=\"hds-credits\">NASA<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>EVA is an example of NASA’s sustained investments to mature capabilities required to reach challenging destinations such as an asteroid, Mars and other planets. Agency administrator Charlie Bolden spoke of the 50<sup>th<\/sup> anniversary of Gemini IV and how its legacy remains a crucial part of spaceflight today.<\/p>\n\n\n\n<p>“This year we celebrate 50 years since Edward White left his Gemini capsule to become America\u2019s first spacewalker,” said Bolden speaking in his “State of NASA” address at the Kennedy Space Center on Feb. 2. “It was only a few years later that we landed humans on the moon.”<\/p>\n\n\n\n<p>Four days of Gemini IV would not only come close to the Russian record, but almost double NASA astronauts’ previous time in space.<\/p>\n\n\n\n<p>Before June 1965, the longest American spaceflight was Gordon Cooper’s 34 hours in space during May 1963 aboard Mercury 9. Soviet cosmonaut Valery Bykovsky spent five days in orbit a month later aboard Vostok 5.<\/p>\n\n\n\n<p>Lifting off from Launch Pad 19 at Cape Kennedy (now Cape Canaveral) Air Force Station on June 3, 1965, Gemini 4 was the first flight to be followed by the mission control at the new Manned Spacecraft Center (MSC) in Houston. MSC grew out of the Space Task Group formed soon after the creation of NASA and originally located at the Langley Research Center in Virginia. Beginning with Project Mercury, that complex was the center of U.S. human spaceflight training and management through Gemini III.<\/p>\n\n\n\n<p>The 1,620-acre MSC complex became the primary flight control center for all subsequent U.S. manned space missions from Project Gemini forward. On Feb. 19, 1973, the center was renamed in honor of the late U.S. president and Texas native, Lyndon B. Johnson.<\/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\/s65-30410\/s65-30410~large.jpg?w=1920&h=1337&fit=clip&crop=faces%2Cfocalpoint\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1920\" height=\"1337\" src=\"https:\/\/images-assets.nasa.gov\/image\/s65-30410\/s65-30410~large.jpg?w=1920&h=1337&fit=clip&crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Flight controllers work at their consoles in Mission Control Center during the Gemini-Titan 4 mission\" 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\/s65-30410\/s65-30410~large.jpg?w=1920&h=1337&fit=crop&crop=faces%2Cfocalpoint 1920w, https:\/\/images-assets.nasa.gov\/image\/s65-30410\/s65-30410~large.jpg?w=300&h=209&fit=crop&crop=faces%2Cfocalpoint 300w, https:\/\/images-assets.nasa.gov\/image\/s65-30410\/s65-30410~large.jpg?w=768&h=535&fit=crop&crop=faces%2Cfocalpoint 768w, https:\/\/images-assets.nasa.gov\/image\/s65-30410\/s65-30410~large.jpg?w=1024&h=713&fit=crop&crop=faces%2Cfocalpoint 1024w, https:\/\/images-assets.nasa.gov\/image\/s65-30410\/s65-30410~large.jpg?w=1536&h=1070&fit=crop&crop=faces%2Cfocalpoint 1536w, https:\/\/images-assets.nasa.gov\/image\/s65-30410\/s65-30410~large.jpg?w=400&h=279&fit=crop&crop=faces%2Cfocalpoint 400w, https:\/\/images-assets.nasa.gov\/image\/s65-30410\/s65-30410~large.jpg?w=600&h=418&fit=crop&crop=faces%2Cfocalpoint 600w, https:\/\/images-assets.nasa.gov\/image\/s65-30410\/s65-30410~large.jpg?w=900&h=627&fit=crop&crop=faces%2Cfocalpoint 900w, https:\/\/images-assets.nasa.gov\/image\/s65-30410\/s65-30410~large.jpg?w=1200&h=836&fit=crop&crop=faces%2Cfocalpoint 1200w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">An overall view of Mission Control at the Manned Spacecraft Center in Houston during the early hours of the Gemini IV flight.

The original plan was to have MSC Public Affairs Director Paul Haney do both the launch and mission commentary from Houston, just like he did for Gemini III. For all previous Mercury and Gemini missions the control center was at the Cape Kennedy launch site.<\/p>\n\n\n\n<p>Scheer directed that Jack King, NASA’s first chief of Public Information at the Florida spaceport, would do the countdown commentary from the Pad 19 blockhouse at the Cape with Haney taking over from Houston at liftoff. This set the precedent for all future human spaceflights with the exception that, beginning with Apollo, the commentary hand-off would be at the point when the rocket cleared the launch tower.<\/p>\n\n\n\n<p>Once in orbit, the first order of business was an attempt to rendezvous with the Titan II booster rocket’s second stage. It proved more difficult than originally thought. There were only two running lights on the stage, and there was no radar on board to give a precise range to the target. McDivitt then decided to concentrate on the more important EVA objective.<\/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\/s65-30427\/s65-30427~large.jpg?w=1920&h=1819&fit=clip&crop=faces%2Cfocalpoint\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1920\" height=\"1819\" src=\"https:\/\/images-assets.nasa.gov\/image\/s65-30427\/s65-30427~large.jpg?w=1920&h=1819&fit=clip&crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Astronaut Edward H.

White II, pilot of the Gemini IV four-day Earth-orbital mission, floats in the zero gravity of space outside the Gemini IV spacecraft.  Behind him is the brilliant blue Earth and its white cloud cover. White wears a specially designed spacesuit; and the visor of the helmet is gold plated to protect him against the unfiltered rays of the sun. He wears an emergency oxygen pack, also. He is secured to the spacecraft by a 25-feet umbilical line and a 23-feet tether line, both wrapped in gold tape to form one cord. In his left hand is a Hand-Held Self-Maneuvering Unit (HHSMU) with which he controls his movements in space.  Astronaut James A. McDivitt, command pilot of the mission, remained inside the spacecraft.
