Naming his spacecraft Sigma 7, Schirra completed six orbits of the Earth, conducting engineering tests of his spacecraft and several experiments including photography of the planet. After he made the first splashdown in the Pacific Ocean, recovery teams brought Sigma 7 with Schirra inside aboard the prime recovery ship the aircraft carrier U.S.S. Kearsarge. From there, Schirra returned to Houston by way of Hawaii. He described his mission as a \u201ctextbook flight\u201d during a press conference at Houston\u2019s Rice University.

Gordon Cooper serving as his backup. Following the tradition of earlier Mercury astronauts, Schirra named his capsule Sigma 7, after the Greek letter \u03a3 often used in engineering and mathematics to symbolize summation, and the \u201c7\u201d representing the seven Mercury astronauts. Schirra chose Sigma to represent the summation of work by thousands of scientists and engineers across the country to make Project Mercury a reality. After his Mercury spacecraft\u2019s arrival in January 1962, some of those very engineers in Cape Caneveral\u2019s Hangar S prepared it for flight. Others readied the Atlas rocket after its arrival at Launch Pad 14 on Aug. 13.<\/p>\n\n\n\n<p><img decoding=\"async\" loading=\"lazy\" alt=\"sigma_7_atlas_static_fire_sep_9_1962\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_4_atlas_static_fire_sep_9_1962.jpg\" width=\"205\" height=\"270\"> <img decoding=\"async\" loading=\"lazy\" alt=\"sigma_7_capsule_lifting_sep_10_1962\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_5_capsule_lifting_sep_10_1962.jpg\" width=\"186\" height=\"270\"> <img decoding=\"async\" loading=\"lazy\" alt=\"schirra_w_jfk_sep_11_1962\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_6_schirra_w_jfk_sep_11_1962_color.jpg\" width=\"238\" height=\"270\"><br>\n<em>Left: Static fire at Launch Pad 14 of the Atlas rocket prior to installation of the Mercury capsule.<br>\nMiddle: Pad workers lift the Mercury capsule for mounting atop the Atlas rocket.

On Sept. 11, during his visit to Cape Canaveral as part of his two-day whirlwind tour of space facilities that also included his famous speech at Rice University in Houston, President John F. Kennedy viewed the assembled rocket, with Schirra serving as his tour guide. Meanwhile, halfway around the world, recovery forces of the U.S. Navy, led by the prime recovery ship the aircraft carrier U.S.S. Kearsarge (CVS-33), assembled northeast of Midway Island, Schirra\u2019s expected splashdown point after a full six-orbit mission.

Eight of the nine new astronauts <a href=\"https:\/\/www.nasa.gov\/history\/60-years-ago-nasa-selects-a-second-group-of-astronauts\/\">selected by NASA<\/a> just two weeks earlier watched as the countdown ticked down to zero and the Atlas rocket carrying Schirra lifted off. Schirra reported to capcom Slayton in the MCC, \u201cI have the liftoff. Clock had started, and she feels real nice.\u201d While the ascent appeared normal to Schirra inside the capsule, ground controllers noticed that the Atlas rocket began to roll at a rate greater than planned. They grew concerned that if the roll persisted, it might cause the rocket to veer off course, triggering an abort and bring Schirra\u2019s flight to a swift and premature end. Soon, the roll stopped, and the flight proceeded as planned, with the two Atlas booster engines shutting down a little more than two minutes after liftoff. The single sustainer engine continued to fire for three more minutes, placing Sigma 7 with Schirra inside into an elliptical 100-by-175-mile orbit, traveling at 17,557 miles per hour. Schirra\u2019s spacecraft separated from the spent rocket, and he turned his capsule around so its blunt heatshield and attached retrorocket pack faced in the direction of flight. Schirra placed the spacecraft into autopilot mode to save fuel and watched the slowly tumbling rocket fade into the distance. He successfully dealt with his first in-orbit problem when his suit began to overheat, causing concern that mission controllers might cut the flight short. But Schirra had a procedure for dealing with the problem, and with the suit temperature returning toward normal, Flight Director Kraft gave a go for the second orbit, allowing the mission to proceed.<\/p>\n\n\n\n<p><img decoding=\"async\" loading=\"lazy\" alt=\"sigma_7_schirra_inflight\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_19_schirra_inflight.jpg\" width=\"274\" height=\"185\"> <img decoding=\"async\" loading=\"lazy\" alt=\"earth_view_s_america_rev_6\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_20_earth_view_s_america_rev_6_s62-06604.jpg\" width=\"185\" height=\"185\"> <img decoding=\"async\" loading=\"lazy\" alt=\"earth_view_cumulus_clouds\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_21_earth_view_cumulus_clouds_s62-06613.jpg\" width=\"185\" height=\"185\"><br>\n<em>Left: Still from a film of astronaut Walter M.

He took a few photographs of the Earth, as the spacecraft\u2019s attitude allowed. The next three orbits transpired without incident, and Schirra began preparing for the all-important retro-fire. He manually oriented Sigma 7, and then returned the spacecraft to automatic control. The retrorockets fired precisely on time to bring Schirra and his spacecraft out of orbit. As the capsule entered the atmosphere, the plasma cloud formed around it prevented communications with the ground for nine minutes. Schirra later described the reentry as \u201cthrilling,\u201d and the spacecraft \u201cas stable as an airplane.\u201d<\/p>\n\n\n\n<p><img decoding=\"async\" loading=\"lazy\" alt=\"sigma_7_descending_on_main\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_22_descending_on_main_img_3121.jpg\" width=\"178\" height=\"225\"> <img decoding=\"async\" loading=\"lazy\" alt=\"sigma_7_splashdown\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_23_splashdown_img_3121.jpg\" width=\"177\" height=\"225\"> <img decoding=\"async\" loading=\"lazy\" alt=\"sigma_7_recovery_ops_kearsarge_w_helo\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_24_recovery_ops_kearsarge_w_helo.jpg\" width=\"283\" height=\"225\"><br>\n<em>Left: Sigma 7 descending under its parachute just before splashdown, photographed from<br>\nthe prime recovery ship the U.S.S.

The orthostatic hypotension had cleared by the following morning. Schirra spent the next three days aboard the Kearsarge as it steamed toward Pearl Harbor in Honolulu, with a brief stop at Midway Island to offload the Sigma 7 spacecraft for its journey back to Cape Canaveral. During that time, he held debriefs with NASA managers and five of his fellow astronauts who had arrived aboard the carrier by aircraft. On Oct. 6, a crowd of 2,000 dignitaries and well-wishers welcomed Schirra at Hickam Air Force Base in Honolulu, where eight-year old Kalani Flood presented him with a traditional lei of red carnations.<\/p>\n\n\n\n<p><img decoding=\"async\" loading=\"lazy\" alt=\"schirra_shaking_hands_with_jay_north\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_34_schirra_shaking_hands_with_jay_north.jpg\" width=\"228\" height=\"160\"> <img decoding=\"async\" loading=\"lazy\" alt=\"_motorcade_through_houston\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_35_motorcade_through_houston.jpg\" width=\"196\" height=\"159\"> <img decoding=\"async\" loading=\"lazy\" alt=\"motorcade_arriving_at_rice\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_36_motorcade_arriving_at_rice.jpg\" width=\"190\" height=\"160\"><br>\n<em>Left: Astronaut Walter M.

Two days later, Schirra flew back to Cape Canaveral to review the data recorded during the mission with engineers and scientists.<\/p>\n\n\n\n<p><img decoding=\"async\" loading=\"lazy\" alt=\"schirra_parade_oradell\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_39_schirra_parade_oradell.jpg\" width=\"329\" height=\"200\"> <img decoding=\"async\" loading=\"lazy\" alt=\"jfk_meeting_with_astronaut_schirra_and_family\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_40_jfk_meeting_with_astronaut_schirra_and_family_194216.jpg\" width=\"240\" height=\"200\"><br>\n<em>Left: Astronaut Walter M.

The next day, a motorcade took them through the streets of the towns, with an estimated 40,000 well-wishers lining the route. At the Oradell football stadium, where 8,000 people had gathered, NASA Administrator Webb presented Schirra with the NASA Distinguished Service Medal for successfully accomplishing the Mercury-Atlas 8 mission and read a message of congratulations from President Kennedy. That evening, the Schirras flew to Washington, D.C., where the next morning, President Kennedy hosted them at the White House. The informal ceremony took place just hours after aides had first shown the President photographic evidence of the buildup of Soviet missiles in Cuba. After leaving the White House, Schirra gave a short speech to employees outside the NASA Headquarters building and signed autographs. Later in the day, Schirra now dressed in his full-dress uniform, received his Navy astronaut wings from Secretary of the Navy Frederick H. Korth. At the end of a long day, the Schirras flew home to Houston. The next morning, Schirra left for Cape Canaveral to finish his debriefings and write his post mission report.<\/p>\n\n\n\n<p><img decoding=\"async\" loading=\"lazy\" alt=\"spacecraft_offloaded_at_midway\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_43_spacecraft_offloaded_at_midway.jpg\" width=\"244\" height=\"190\"> <img decoding=\"async\" loading=\"lazy\" alt=\"pacecraft_arr_hangar\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_44_spacecraft_arr_hangar_s0.jpg\" width=\"144\" height=\"190\"> <img decoding=\"async\" loading=\"lazy\" alt=\"sigma_7_at_kscvc\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2022\/10\/sigma_7_45_at_kscvc.jpg\" width=\"223\" height=\"190\"><br>\n<em>Left: Ground crews unload Sigma 7 from the U.S.S.

Workers offloaded the Mercury capsule from the Kearsarge at Midway Island and placed it aboard a C-130 Hercules cargo aircraft for the flight back to Cape Canaveral. Workers in Hangar S inspected the spacecraft to assess any effects from its nine-hour orbital flight. From there, ground crews trucked Sigma 7 to its manufacturing site, the McDonnell Aircraft Corp. plant in St. Louis, where engineers gave it a more thorough inspection. After spending some time on display at the McDonnell plant, Sigma 7 went on a limited world tour until Sept. 20, 1967, when NASA transferred ownership to the Smithsonian Institution. For the next 27 years, Sigma 7 remained on exhibit at the U.S. Space and Rocket Center in Huntsville, Alabama, before transferring to the U.S. Astronaut Hall of Fame in Titusville, Florida, in March 1990. When that facility closed in November 2015, Sigma 7 relocated to NASA\u2019s Kennedy Space Center Visitor Complex in Florida, where it remains on display in the <a rel=\"noopener\" href=\"https:\/\/www.kennedyspacecenter.com\/blog\/attraction-spotlight-heroes-and-legends\">Heroes and Legends Hall<\/a>, oddly mated to a Redstone rocket.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"THE FLIGHT OF SIGMA 7 - Mercury-Atlas 8 (1962) - NASA documentary\" width=\"500\" height=\"375\" src=\"https:\/\/www.youtube.com\/embed\/Ra4yAtPA4gU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer;
