175-562: Mercury-Atlas was a subprogram of Project Mercury that included most of the flights and tests using the Atlas LV-3B launch vehicle. The Atlas was also used for one Mercury flight under the Big Joe subprogram. The Mercury mission numbering system was: a two-letter designation marking the launch vehicle type, followed by a dash, then a number designating the flight/test number. The Atlas launch vehicles used for Project Mercury were given

350-665: A Scout rocket attempted to launch a specialized satellite equipped with Mercury communications components for testing the ground tracking network, but the booster failed soon after liftoff. The Little Joe program used seven airframes for eight flights, of which three were successful. The second Little Joe flight was named Little Joe 6, because it was inserted into the program after the first 5 airframes had been allocated. Production spacecraft and boilerplates were used for these test flights. Dwight Eisenhower Dwight David Eisenhower (born David Dwight Eisenhower ; October 14, 1890 – March 28, 1969), also known by his nickname Ike ,

525-531: A containment policy to stop Soviet expansion. In June 1943, a visiting politician had suggested to Eisenhower that he might become president after the war. Believing that a general should not participate in politics, Merlo J. Pusey wrote that "figuratively speaking, [Eisenhower] kicked his political-minded visitor out of his office". As others asked him about his political future, Eisenhower told one that he could not imagine wanting to be considered for any political job "from dogcatcher to Grand High Supreme King of

700-487: A launch escape system to separate the spacecraft and its occupant from the launch vehicle in case of impending failure; attitude control for orientation of the spacecraft in orbit; a retrorocket system to bring the spacecraft out of orbit; drag braking blunt body for atmospheric reentry ; and landing on water. To communicate with the spacecraft during an orbital mission, an extensive communications network had to be built. In keeping with his desire to keep from giving

875-608: A very bloody large-scale battle , and the Germans finally surrendered on May 7, 1945. Throughout 1945, the allied armies liberated numerous Nazi concentration camps throughout Europe. As the allies learned the full extend of the Holocaust , Eisenhower anticipated that, in the future, attempts to recharacterize Nazi crimes as propaganda ( Holocaust denial ) would be made, and took steps against it by demanding extensive photo and film documentation of Nazi death camps . Following

1050-489: A 15-hour hold, during which pyrotechnics were installed. Then came the main countdown which for orbital flights started 6½ hours before launch (T – 390 min), counted backwards to launch (T = 0) and then forward until orbital insertion (T + 5 min). On an orbital mission, the Atlas' rocket engines were ignited four seconds before lift-off. The launch vehicle was held to the ground by clamps and then released when sufficient thrust

1225-657: A basic golf facility installed at Camp David, and he became close friends with the Augusta National Chairman Clifford Roberts , inviting Roberts to stay at the White House on numerous occasions. Roberts, an investment broker, also handled the Eisenhower family's investments. He began oil painting while at Columbia University, after watching Thomas E. Stephens paint Mamie's portrait. Eisenhower painted about 260 oils during

1400-498: A blunt, forward-facing heat shield could solve the problem of heating. T. Keith Glennan had been appointed the first Administrator of NASA, with Hugh L. Dryden (last Director of NACA) as his Deputy, at the creation of the agency on October 1, 1958. Glennan would report to the president through the National Aeronautics and Space Council . The group responsible for Project Mercury was NASA's Space Task Group , and

1575-854: A broken-down Tin Lizzie , loaded with paint, has been driven over it". Angels in the Outfield was Eisenhower's favorite movie. His favorite reading material for relaxation was the Western novels of Zane Grey . With his excellent memory and ability to focus, Eisenhower was skilled at cards. He learned poker, which he called his "favorite indoor sport", in Abilene. Eisenhower recorded West Point classmates' poker losses for payment after graduation and later stopped playing because his opponents resented having to pay him. A friend reported that after learning to play contract bridge at West Point, Eisenhower played

1750-464: A camp for thousands of troops and developing a full combat training schedule. After the war, Eisenhower reverted to his regular rank of captain and a few days later was promoted to major , a rank he held for 16 years. The major was assigned in 1919 to a transcontinental Army convoy to test vehicles and dramatize the need for improved roads. Indeed, the convoy averaged only 5 miles per hour (8.0 km/h) from Washington, D.C. to San Francisco; later

1925-584: A centrifuge at the Naval Air Development Center , and were taught special breathing techniques necessary when subjected to more than 6 g. Weightlessness training took place in aircraft, first on the rear seat of a two-seater fighter and later inside converted and padded cargo aircraft . They practiced gaining control of a spinning spacecraft in a machine at the Lewis Flight Propulsion Laboratory called

2100-455: A college degree in a STEM subject. The college degree requirement excluded the USAF's X-1 pilot, then-Lt Col (later Brig Gen) Chuck Yeager , the first person to exceed the speed of sound . He later became a critic of the project, ridiculing the civilian space program, labeling astronauts as "spam in a can." John Glenn did not have a college degree either, but used influential friends to make

2275-432: A convex base, which carried a heat shield (Item 2 in the diagram below) consisting of an aluminum honeycomb covered with multiple layers of fiberglass . Strapped to it was a retropack ( 1 ) consisting of three rockets deployed to brake the spacecraft during reentry. Between these were three posigrade rockets: minor rockets for separating the spacecraft from the launch vehicle at orbital insertion. The straps that held

2450-451: A cuff that could take his blood pressure, and a rectal thermometer to record his temperature (this was replaced by an oral thermometer on the last flight). Data from these was sent to the ground during the flight. The astronaut normally drank water and ate food pellets. Despite the lessons learnt from the U2 program, which also utilized a pressure suit, initially no urine collection device

2625-582: A day-long, 22 orbit flight. However, the Soviet Union ended its Vostok program the next month, with the human spaceflight endurance record set by the 82-orbit, almost 5-day Vostok 5 flight. All of the six crewed Mercury flights were successful, though some planned flights were canceled during the project (see below). The main medical problems encountered were simple personal hygiene , and post-flight symptoms of low blood pressure . The launch vehicles had been tested through uncrewed flights, therefore

2800-574: A dog into orbit. Though the animal was not recovered alive, it was obvious their goal was human spaceflight. Unable to disclose details of military space projects, President Eisenhower ordered the creation of a civilian space agency in charge of civilian and scientific space exploration. Based on the federal research agency National Advisory Committee for Aeronautics (NACA), it was named the National Aeronautics and Space Administration (NASA). The agency achieved its first goal of launching

2975-436: A fuel. For orientation, the pilot could look through the window in front of him or he could look at a screen connected to a periscope with a camera which could be turned 360°. The Mercury astronauts had taken part in the development of their spacecraft, and insisted that manual control, and a window, be elements of its design. As a result, spacecraft movement and other functions could be controlled three ways: remotely from

3150-719: A full staff of technical personnel around solely to fly a few Mercury capsules would result in excessively high costs. Orbital missions required use of the Atlas LV-3B , a man-rated version of the Atlas D which was originally developed as the United States ' first operational intercontinental ballistic missile (ICBM) by Convair for the Air Force during the mid-1950s. The Atlas was a "one-and-one-half-stage" rocket fueled by kerosene and liquid oxygen (LOX). The rocket by itself stood 67 feet (20 m) high; total height of

3325-670: A life-threatening stomach ailment but recovered fully. Eisenhower was promoted to the rank of permanent lieutenant colonel in 1936. He also learned to fly with the Philippine Army Air Corps at the Zablan Airfield in Camp Murphy under Capt. Jesus Villamor , making a solo flight over the Philippines in 1937, and obtained his private pilot's license in 1939 at Fort Lewis . Also around this time, he

3500-513: A liquid-fueled engine that burned alcohol and liquid oxygen producing about 75,000 pounds-force (330 kN) of thrust, which was not enough for orbital missions. It was a descendant of the German V-2 , and developed for the U.S. Army during the early 1950s. It was modified for Project Mercury by removing the warhead and adding a collar for supporting the spacecraft together with material for damping vibrations during launch. Its rocket motor

3675-436: A low pressure of 5.5 psi or 38 kPa (equivalent to an altitude of 24,800 feet or 7,600 metres) was chosen, rather than one with the same composition as air ( nitrogen /oxygen) at sea level. This was easier to control, avoided the risk of decompression sickness ("the bends"), and also saved on spacecraft weight. Fires (which never occurred during the course of Project Mercury) would have to be extinguished by emptying

3850-484: A man's character by the way he plays cards. Eisenhower is a calm and collected player and never whines at his losses. He is brilliant in victory but never commits the bridge player's worst crime of gloating when he wins." Bridge expert Oswald Jacoby frequently participated in the White House games and said, "The President plays better bridge than golf. He tries to break 90 at golf. At bridge, you would say he plays in

4025-473: A military mistake for him to attack Berlin and said orders to that effect would have to be explicit. The British backed down but then wanted Eisenhower to move into Czechoslovakia for political reasons. Washington refused to support Churchill's plan to use Eisenhower's army for political maneuvers against Moscow . The actual division of Germany followed the lines that Roosevelt, Churchill and Stalin had previously agreed upon. The Soviet Red Army captured Berlin in

4200-562: A missile race. The rocket technology in turn enabled both sides to develop Earth-orbiting satellites for communications, and gathering weather data and intelligence . Americans were shocked when the Soviet Union placed the first satellite into orbit in October 1957, leading to a growing fear that the US was falling into a " missile gap ". A month later, the Soviets launched Sputnik 2 , carrying

4375-563: A pessimistic assessment, stating he had an "uneasy feeling" about Chaney and his staff. On June 23, 1942, he returned to London as Commanding General, European Theater of Operations (ETOUSA), based in London and with a house in Coombe, Kingston upon Thames , and took over command of ETOUSA from Chaney. He was promoted to lieutenant general on July 7. In November 1942, Eisenhower was also appointed Supreme Commander Allied Expeditionary Force of

4550-474: A railroad mechanic and then at a creamery. By 1898, the parents made a decent living and provided a suitable home for their large family. Eisenhower was born David Dwight Eisenhower in Denison, Texas, on October 14, 1890, the third of seven sons born to Ida and David. His mother soon reversed his two forenames after his birth to avoid the confusion of having two Davids in the family. He was named Dwight after

4725-400: A rocket sled track at Holloman Air Force Base at Alamogordo, New Mexico were used for aerodynamic studies. Both Navy and Air Force aircraft were made available for the development of the spacecraft's landing system, and Navy ships and Navy and Marine Corps helicopters were made available for recovery. South of Cape Canaveral the town of Cocoa Beach boomed. From here, 75,000 people watched

4900-935: A satellite into space, the Pioneer 1 , in 1958. The next goal was to put a man there. The limit of space (also known as the Kármán line ) was defined at the time as a minimum altitude of 62 mi (100 km), and the only way to reach it was by using rocket-powered boosters. This created risks for the pilot, including explosion, high g-forces and vibrations during lift off through a dense atmosphere, and temperatures of more than 10,000 °F (5,500 °C) from air compression during reentry. In space, pilots would require pressurized chambers or space suits to supply fresh air. While there, they would experience weightlessness , which could potentially cause disorientation. Further potential risks included radiation and micrometeoroid strikes, both of which would normally be absorbed in

5075-576: A spaceflight, and was consequently dropped. The heat shield and the stability of the spacecraft were tested in wind tunnels , and later in flight. The launch escape system was developed through uncrewed flights. During a period of problems with development of the landing parachutes, alternative landing systems such as the Rogallo glider wing were considered, but ultimately scrapped. The spacecraft were produced at McDonnell Aircraft , St. Louis , Missouri, in clean rooms and tested in vacuum chambers at

5250-597: A two- or three-digit number followed by a "-D", indicating that they were the "D" version of the Atlas. The missions flown in Mercury-Atlas were: Project Mercury Project Mercury was the first human spaceflight program of the United States, running from 1958 through 1963. An early highlight of the Space Race , its goal was to put a man into Earth orbit and return him safely, ideally before

5425-539: A unit that trained tank crews. Between the wars he served in staff positions in the US and the Philippines, reaching the rank of brigadier general shortly before the entry of the US into World War II in 1941. After further promotion Eisenhower oversaw the Allied invasions of North Africa and Sicily before supervising the invasions of France and Germany . After the war ended in Europe, he served as military governor of

5600-408: A voracious reader on the subject. Other favorite subjects early in his education were arithmetic and spelling. Eisenhower's parents set aside specific times at breakfast and at dinner for daily family Bible reading. Chores were regularly assigned and rotated among all the children, and misbehavior was met with unequivocal discipline, usually from David. His mother, previously a member (with David) of

5775-482: Is named, married Richard Nixon 's daughter Julie in 1968. Eisenhower was a golf enthusiast later in life, and he joined the Augusta National Golf Club in 1948. He played golf frequently during and after his presidency and was unreserved in his passion for the game, to the point of golfing during winter; he ordered his golf balls painted black so he could see them better against snow. He had

5950-679: The Allied forces 2 to 1. In December 1943, President Roosevelt decided that Eisenhower – not Marshall – would be Supreme Allied Commander in Europe. The following month, he resumed command of ETOUSA and the following month was officially designated as the Supreme Allied Commander of the Allied Expeditionary Force (SHAEF), serving in a dual role until the end of hostilities in Europe in May 1945. He

6125-590: The American-occupied zone of Germany (1945), Army Chief of Staff (1945–1948), president of Columbia University (1948–1953), and as the first supreme commander of NATO (1951–1952). In 1952, Eisenhower entered the presidential race as a Republican to block the isolationist foreign policies of Senator Robert A. Taft , who opposed NATO . Eisenhower won that year's election and the 1956 election in landslides , both times defeating Adlai Stevenson II . Eisenhower's main goals in office were to contain

6300-814: The Army Industrial College in 1933 and later served on the faculty (it was later expanded to become the Industrial College of the Armed Services and is now known as the Dwight D. Eisenhower School for National Security and Resource Strategy). His primary duty was planning for the next war, which proved most difficult in the midst of the Great Depression . He then was posted as chief military aide to General Douglas MacArthur, Army Chief of Staff. In 1932, he participated in

6475-722: The Civil Rights Act of 1957 and sent Army troops to enforce federal court orders which integrated schools in Little Rock, Arkansas . His administration undertook the development and construction of the Interstate Highway System , which remains the largest construction of roadways in American history. In 1957, following the Soviet launch of Sputnik , Eisenhower led the American response which included

6650-546: The Command and General Staff College at Fort Leavenworth , Kansas, where he graduated first in a class of 245 officers. During the late 1920s and early 1930s, Eisenhower's career stalled somewhat, as military priorities diminished; many of his friends resigned for high-paying business jobs. He was assigned to the American Battle Monuments Commission directed by General Pershing, and with

6825-574: The Freedom 7 capsule demonstrated the ability to withstand the high g-forces of launch and atmospheric re-entry . Shepard later went on to fly in the Apollo program and became the only Mercury astronaut to walk on the Moon on Apollo 14 . Gus Grissom became the second American in space on Mercury-Redstone 4 on July 21, 1961. After the splashdown of Liberty Bell 7 , the side hatch opened and caused

7000-504: The French armed forces . The Allied leaders were "thunderstruck" by this from a political standpoint, though none had offered Eisenhower guidance with the problem in planning the operation. Eisenhower was severely criticized for the move. Darlan was assassinated on December 24 by Fernand Bonnier de La Chapelle , a French antifascist monarchist. Eisenhower later appointed as High Commissioner General Henri Giraud , who had been installed by

7175-598: The Geneva Convention . Eisenhower followed the orders laid down by the Joint Chiefs of Staff (JCS) in directive JCS 1067 but softened them by bringing in 400,000 tons of food for civilians and allowing more fraternization . In response to the devastation in Germany, including food shortages and an influx of refugees, he arranged distribution of American food and medical equipment. His actions reflected

7350-688: The Italian leader , had fallen in Italy, the Allies switched their attention to the mainland with Operation Avalanche . But while Eisenhower argued with President Roosevelt and British Prime Minister Churchill, who both insisted on unconditional surrender in exchange for helping the Italians, the Germans pursued an aggressive buildup of forces in the country. The Germans made the already tough battle more difficult by adding 19 divisions and initially outnumbering

7525-714: The Japanese attack on Pearl Harbor , Eisenhower was assigned to the General Staff in Washington , where he served until June 1942 with responsibility for creating the major war plans to defeat Japan and Germany. He was appointed Deputy Chief in charge of Pacific Defenses under the Chief of War Plans Division (WPD), General Leonard T. Gerow , and then succeeded Gerow as Chief of the War Plans Division. Next, he

7700-474: The Mission Control Center . Recovery was practiced in pools at Langley , and later at sea with frogmen and helicopter crews. A Redstone rocket was used to boost the capsule for 2 minutes and 30 seconds to an altitude of 32 nautical miles (59 km); the capsule continued ascending on a ballistic curve after booster separation. The launch escape system was jettisoned at the same time. At

The word "expeditionary" was dropped soon after his appointment for security reasons. The campaign in North Africa was designated Operation Torch and was planned in the underground headquarters within the Rock of Gibraltar . Eisenhower was the first non-British person to command Gibraltar in 200 years. French cooperation

8050-555: The Panama Canal Zone , where, joined by Mamie, he served until 1924. Under Conner's tutelage, he studied military history and theory (including Carl von Clausewitz 's On War ), and later cited Conner's enormous influence on his military thinking, saying in 1962 that "Fox Conner was the ablest man I ever knew." Conner's comment on Eisenhower was, "[He] is one of the most capable, efficient and loyal officers I have ever met." On Conner's recommendation, in 1925–1926 he attended

8225-613: The Redstone and Atlas D missiles. The capsule was fitted with a launch escape rocket to carry it safely away from the launch vehicle in case of a failure. The flight was designed to be controlled from the ground via the Manned Space Flight Network , a system of tracking and communications stations; back-up controls were outfitted on board. Small retrorockets were used to bring the spacecraft out of its orbit, after which an ablative heat shield protected it from

8400-745: The River Brethren ( Brethren in Christ Church ) sect of the Mennonites , joined the International Bible Students Association , later known as Jehovah's Witnesses . The Eisenhower home served as the local meeting hall from 1896 to 1915, though Dwight never joined. His later decision to attend West Point saddened his mother, who felt that warfare was "rather wicked", but she did not overrule his decision. Speaking of himself in 1948, Eisenhower said he

8575-534: The Soviet Union . Taken over from the US Air Force by the newly created civilian space agency NASA , it conducted 20 uncrewed developmental flights (some using animals), and six successful flights by astronauts . The program, which took its name from Roman mythology , cost $ 2.68 billion (adjusted for inflation ). The astronauts were collectively known as the " Mercury Seven ", and each spacecraft

8750-591: The Suez Crisis of 1956, he condemned the Israeli, British, and French invasion of Egypt, and he forced them to withdraw. He also condemned the Soviet invasion during the Hungarian Revolution of 1956 but took no action. He deployed 15,000 soldiers during the 1958 Lebanon crisis . Near the end of his term, a summit meeting with the Soviet leader Nikita Khrushchev was cancelled when a US spy plane

8925-702: The creation of NASA and the establishment of a stronger, science-based education via the National Defense Education Act . The Soviet Union began to reinforce their own space program , escalating the Space Race . His two terms saw unprecedented economic prosperity except for a minor recession in 1958 . In his farewell address , he expressed his concerns about the dangers of massive military spending , particularly deficit spending and government contracts to private military manufacturers, which he dubbed "the military–industrial complex ". Historical evaluations of his presidency place him among

9100-509: The upper tier of American presidents . The Eisenhauer (German for "iron hewer" or "iron miner") family migrated from the German village of Karlsbrunn to the Province of Pennsylvania in 1741. Accounts vary as to how and when the German name Eisenhauer was anglicized . David Jacob Eisenhower, Eisenhower's father, was a college-educated engineer, despite his own father's urging to stay on

9275-554: The 70s." Eisenhower served initially in logistics and then the infantry at various camps in Texas and Georgia until 1918. When the US entered World War I , he immediately requested an overseas assignment but was denied and assigned to Ft. Leavenworth, Kansas . In February 1918, he was transferred to Camp Meade in Maryland with the 65th Engineers . His unit was later ordered to France, but, to his chagrin, he received orders for

9450-619: The AFHQ to the SHAEF. Many thought that victory in Europe would come by summer's end, but the Germans did not capitulate for almost a year. From then until the end of the war in Europe on May 8, 1945, Eisenhower, through SHAEF, commanded all Allied forces, and through his command of ETOUSA had administrative command of all US forces on the Western Front north of the Alps . He was ever mindful of

9625-735: The Allied command, on December 20, 1944, he was promoted to General of the Army , equivalent to the rank of Field Marshal in most European armies. In this and the previous high commands he held, Eisenhower showed his great talents for leadership and diplomacy. Although he had never seen action himself, he won the respect of front-line commanders. He interacted adeptly with allies such as Winston Churchill , Field Marshal Bernard Montgomery and General Charles de Gaulle . He had serious disagreements with Churchill and Montgomery over questions of strategy, but these rarely upset his relationships with them. He dealt with Soviet Marshal Zhukov , his Russian counterpart, and they became good friends. In December 1944,

9800-549: The Allies as Darlan's commander-in-chief. Operation Torch also served as a valuable training ground for Eisenhower's combat command skills; during the initial phase of Generalfeldmarschall Erwin Rommel 's move into the Kasserine Pass , Eisenhower created some confusion in the ranks by interference with the execution of battle plans by his subordinates. He also was initially indecisive in his removal of Lloyd Fredendall , commanding II Corps . He became more adroit in such matters in later campaigns. In February 1943, his authority

9975-431: The Atlas-Mercury space vehicle at launch was 95 feet (29 m). The Atlas first stage was a booster skirt with two engines burning liquid fuel. This, together with the larger sustainer second stage, gave it sufficient power to launch a Mercury spacecraft into orbit. Both stages fired from lift-off with the thrust from the second stage sustainer engine passing through an opening in the first stage. After separation from

My decision to attack at this time and place was based on the best information available. The troops, the air and the Navy did all that bravery and devotion to duty could do. If any blame or fault attaches to the attempt, it is mine alone. Every ground commander seeks the battle of annihilation; so far as conditions permit, he tries to duplicate in modern war

10325-438: The Earth. Here the spacecraft fired the three posigrade rockets for a second to separate it from the launch vehicle. Just before orbital insertion and sustainer engine cutoff, g-loads peaked at 8 g (6 g for a suborbital flight). In orbit, the spacecraft automatically turned 180°, pointed the retropackage forward and its nose 14.5° downward and kept this attitude for the rest of the orbital phase to facilitate communication with

10500-420: The Earth. When Mercury ended in May 1963, both nations had sent six people into space, but the Soviets led the US in total time spent in space. The Mercury space capsule was produced by McDonnell Aircraft , and carried supplies of water, food and oxygen for about one day in a pressurized cabin . Mercury flights were launched from Cape Canaveral Air Force Station in Florida, on launch vehicles modified from

10675-463: The German unconditional surrender, Eisenhower was appointed military governor of the American-occupied zone of Germany, located primarily in Southern Germany , and headquartered in Frankfurt am Main . Upon discovery of the Nazi concentration camps , he ordered camera crews to document evidence for use in the Nuremberg Trials . He reclassified German prisoners of war (POWs) in US custody as Disarmed Enemy Forces (DEFs), who were no longer subject to

Since the USSR did not have bases in the western hemisphere from which to deploy bomber planes , Joseph Stalin decided to develop intercontinental ballistic missiles , which drove

11200-484: The McDonnell plant. The spacecraft had close to 600 subcontractors, such as Garrett AiResearch which built the spacecraft's environmental control system. Final quality control and preparations of the spacecraft were made at Hangar S at Cape Canaveral. NASA ordered 20 production spacecraft, numbered 1 through 20. Five of the 20, Nos. 10, 12, 15, 17, and 19, were not flown. Spacecraft No. 3 and No. 4 were destroyed during uncrewed test flights. Spacecraft No. 11 sank and

A further measure for finding the right attitude in orbit was star and Earth recognition training in planetaria and simulators. Communication and flight procedures were practiced in flight simulators, first together with a single person assisting them and later with

11725-497: The Pacific. Eisenhower also insisted that the British give him exclusive command over all strategic air forces to facilitate Overlord, to the point of threatening to resign unless Churchill relented, which he did. Eisenhower then designed a bombing plan in France in advance of Overlord and argued with Churchill over the latter's concern with civilian casualties; de Gaulle interjected that the casualties were justified, and Eisenhower prevailed. He also had to skillfully manage to retain

11900-416: The Philippines, which was denied; because of the ongoing Mexican Revolution , he was posted to Fort Sam Houston in San Antonio , Texas, under the command of General Funston. In 1916, while stationed at Fort Sam Houston, Funston convinced him to become the football coach for Peacock Military Academy ; he later became the coach at St. Louis College, now St. Mary's University , and was an honorary member of

12075-428: The Redstone Arsenal in Huntsville, was considered as well for intermediate Mercury suborbital flights at a higher speed and altitude than Redstone, but this plan was dropped when it turned out that man-rating Jupiter for the Mercury program would actually cost more than flying an Atlas due to economics of scale. Jupiter's only use other than as a missile system was for the short-lived Juno II launch vehicle, and keeping

12250-508: The Sigma Beta Chi fraternity there. While Eisenhower was stationed in Texas, he met Mamie Doud of Boone, Iowa . They were immediately taken with each other. He proposed to her on Valentine's Day in 1916. A November wedding date in Denver was moved up to July 1 due to the impending American entry into World War I ; Funston approved 10 days of leave for their wedding. The Eisenhowers moved many times during their first 35 years of marriage. The Eisenhowers had two sons. In late 1917 while he

Twelve companies bid to build

12600-909: The Universe", and another that he could not serve as Army Chief of Staff if others believed he had political ambitions. In 1945, Truman told Eisenhower during the Potsdam Conference that if desired, the president would help the general win the 1948 election , and in 1947 he offered to run as Eisenhower's running mate on the Democratic ticket if MacArthur won the Republican nomination. As the election approached, other prominent citizens and politicians from both parties urged Eisenhower to run. In January 1948, after learning of plans in New Hampshire to elect delegates supporting him for

12775-496: The World Wide Tracking Network, a chain of 18 stations placed around the equator, which was based on a network used for satellites and made ready in 1960. It collected data from the spacecraft and provided two-way communication between the astronaut and the ground. Each station had a range of 700 nautical miles (1,300 km) and a pass typically lasted 7 minutes. Mercury astronauts on the ground would take

12950-411: The air around the spacecraft. After reentry, a small, drogue parachute ( H ) was deployed at 21,000 ft (6,400 m) for stabilizing the spacecraft's descent. The main parachute ( I ) was deployed at 10,000 ft (3,000 m) starting with a narrow opening that opened fully in a few seconds to lessen the strain on the lines. Just before hitting the water, the landing bag inflated from behind

13125-433: The angle of retrofire was 34° downward from the flight path angle. Retrorockets fired for 10 seconds each ( F ) in a sequence where one started 5 seconds after the other. During reentry ( G ), the astronaut would experience about 8 g (11–12 g on a suborbital mission). The temperature around the heat shield rose to 3,000 °F (1,600 °C) and at the same time, there was a two-minute radio blackout due to ionization of

13300-422: The astronauts' tasks was publicity; they gave interviews to the press and visited project manufacturing facilities to speak with those who worked on Project Mercury. The press was especially fond of John Glenn, who was considered the best speaker of the seven. They sold their personal stories to Life magazine which portrayed them as 'patriotic, God-fearing family men.' Life was also allowed to be at home with

13475-431: The atmosphere. All seemed possible to overcome: experience from satellites suggested micrometeoroid risk was negligible, and experiments in the early 1950s with simulated weightlessness, high g-forces on humans, and sending animals to the limit of space, all suggested potential problems could be overcome by known technologies. Finally, reentry was studied using the nuclear warheads of ballistic missiles, which demonstrated

13650-470: The baseball team at West Point was one of the greatest disappointments of my life, maybe my greatest". He made the varsity football team and was a starter at halfback in 1912, when he tried to tackle the legendary Jim Thorpe of the Carlisle Indians . Eisenhower suffered a torn knee while being tackled in the next game, which was the last he played; he reinjured his knee on horseback and in

13825-647: The beginning of Project Gemini . On March 13, 1972, after doctors confirmed he no longer had a coronary condition, Slayton returned to flight status and the next year was assigned to the Apollo–Soyuz Test Project , which successfully flew in 1975 with Slayton as the docking module pilot. After the ASTP, he managed the Space Shuttle Program's Approach and Landing Tests (ALT) and Orbital Flight Tests (OFT) before retiring from NASA in 1982. One of

14000-456: The boxing ring, so he turned to fencing and gymnastics. Eisenhower later served as junior varsity football coach and cheerleader, which caught the attention of General Frederick Funston . He graduated from West Point in the middle of the class of 1915, which became known as " the class the stars fell on ", because 59 members eventually became general officers . After graduation in 1915, Second Lieutenant Eisenhower requested an assignment in

14175-502: The cabin of oxygen. In such case, or failure of the cabin pressure for any reason, the astronaut could make an emergency return to Earth, relying on his suit for survival. The astronauts normally flew with their visor up, which meant that the suit was not inflated. With the visor down and the suit inflated, the astronaut could only reach the side and bottom panels, where vital buttons and handles were placed. The astronaut also wore electrodes on his chest to record his heart rhythm ,

14350-645: The capsule to sink although Grissom was able to be safely recovered. His flight also gave NASA the confidence to move on to orbital flights. Grissom went on to participate in the Gemini and Apollo programs, but died in January 1967 during a pre-launch test for Apollo 1 . John Glenn became the first American to orbit the Earth on Mercury-Atlas 6 February 20, 1962. During the flight, the spacecraft Friendship 7 experienced issues with its automatic control system but Glenn

14525-406: The capsule was just large enough for a single crew member. Inside were 120 controls: 55 electrical switches, 30 fuses and 35 mechanical levers. The heaviest spacecraft, Mercury-Atlas 9, weighed 3,000 pounds (1,400 kg) fully loaded. Its outer skin was made of René 41 , a nickel alloy able to withstand high temperatures. The spacecraft was cone shaped, with a neck at the narrow end. It had

14700-442: The center and south of the front (respectively). Eisenhower worked tirelessly to address the demands of the rival commanders to optimize Allied forces, often by giving them tactical latitude; many historians conclude this delayed the Allied victory in Europe. However, due to Eisenhower's persistence, the pivotal supply port at Antwerp was successfully, albeit belatedly, opened in late 1944 . In recognition of his senior position in

14875-475: The classic example of Cannae . Once the coastal assault had succeeded, Eisenhower insisted on retaining personal control over the land battle strategy and was immersed in the command and supply of multiple assaults through France on Germany. Field Marshal Montgomery insisted priority be given to his 21st Army Group 's attack being made in the north, while Generals Bradley ( 12th US Army Group ) and Devers ( Sixth US Army Group ) insisted they be given priority in

15050-753: The clearing of the Bonus March encampment in Washington, D.C. Although he was against the actions taken against the veterans and strongly advised MacArthur against taking a public role in it, he later wrote the Army's official incident report, endorsing MacArthur's conduct. In 1935, he accompanied MacArthur to the Philippines, where he served as assistant military adviser to the Philippine government in developing their army. MacArthur allowed Eisenhower to handpick an officer whom he thought would contribute to

15225-555: The design submitted as "C" in November 1958. After it failed a test flight in July 1959, a final configuration, "D", emerged. The heat shield shape had been developed earlier in the 1950s through experiments with ballistic missiles, which had shown a blunt profile would create a shock wave that would lead most of the heat around the spacecraft. To further protect against heat, either a heat sink , or an ablative material, could be added to

15400-475: The escape tower. McDonnell also built the spacecraft simulators used by the astronauts during training, and adopted the motto "First Free Man in Space". A 55-foot-long (17 m) launch vehicle called Little Joe was used for uncrewed tests of the launch escape system, using a Mercury capsule with an escape tower mounted on it. Its main purpose was to test the system at max q , when aerodynamic forces against

15575-439: The evangelist Dwight L. Moody . All of the boys were nicknamed "Ike", such as "Big Ike" ( Edgar ) and "Little Ike" (Dwight); the nickname was intended as an abbreviation of their last name. By World War II, only Dwight was still called "Ike". In 1892, the family moved to Abilene, Kansas, which Eisenhower considered his hometown. As a child, he was involved in an accident that cost his younger brother Earl an eye, for which he

15750-620: The families while the astronauts were in space. During the project, Grissom, Carpenter, Cooper, Schirra and Slayton stayed with their families at or near Langley Air Force Base; Glenn lived at the base and visited his family in Washington DC on weekends. Shepard lived with his family at Naval Air Station Oceana in Virginia. Other than Grissom, who was killed in the 1967 Apollo 1 fire, the other six survived past retirement and died between 1993 and 2016. Prior to Project Mercury, there

15925-667: The family farm. Eisenhower's mother, Ida Elizabeth (Stover) Eisenhower , of predominantly German Protestant ancestry, moved to Kansas from Virginia. She married David on September 23, 1885, in Lecompton, Kansas , on the campus of their alma mater, Lane University . David owned a general store in Hope, Kansas , but the business failed due to economic conditions and the family became impoverished. The Eisenhowers lived in Texas from 1889 until 1892, and later returned to Kansas, with $ 24 (equivalent to $ 814 in 2023) to their name. David worked as

16100-455: The first American orbital flight being launched in 1962. The Mercury spacecraft's principal designer was Maxime Faget , who started research for human spaceflight during the time of the NACA. It was 10.8 feet (3.3 m) long and 6.0 feet (1.8 m) wide; with the launch escape system added, the overall length was 25.9 feet (7.9 m). With 100 cubic feet (2.8 m ) of habitable volume,

16275-468: The first crewed Apollo mission, Apollo 7 , becoming the first astronaut to fly three times and the only person to fly in the Mercury, Gemini, and Apollo programs. Gordon Cooper made the last flight of Project Mercury with Mercury-Atlas 9 on May 15, 1963. His flight onboard Faith 7 set another U.S. endurance record with a 34-hour and 19 minute flight duration, and 22 completed orbits. This mission marks

16450-511: The first person in space on an orbital flight. Alan Shepard became the first American in space on a suborbital flight three weeks later, on May 5, 1961. John Glenn, the third Mercury astronaut to fly, became the first American to reach orbit on February 20, 1962, but only after the Soviets had launched a second cosmonaut, Gherman Titov , into a day-long flight in August 1961. Three more Mercury orbital flights were made, ending on May 16, 1963, with

16625-536: The first stage, the sustainer stage continued alone. The sustainer also steered the rocket by thrusters guided by gyroscopes. Smaller vernier rockets were added on its sides for precise control of maneuvers. NASA announced the following seven astronauts – known as the Mercury Seven – on April 9, 1959: Alan Shepard became the first American in space by making a suborbital flight on May 5, 1961. Mercury-Redstone 3 , Shepard's 15 minute and 28 second flight of

16800-472: The first to use such a weapon." Initially, Eisenhower hoped for cooperation with the Soviets. He even visited Warsaw in 1945. Invited by Bolesław Bierut and decorated with the highest military decoration , he was shocked by the scale of destruction in the city. However, by mid-1947, as east–west tensions over economic recovery in Germany and the Greek Civil War escalated, Eisenhower agreed with

16975-405: The flight. On the morning of the trip he typically ate a steak breakfast. After having sensors applied to his body and being dressed in the pressure suit, he started breathing pure oxygen to prepare him for the atmosphere of the spacecraft. He arrived at the launch pad, took the elevator up the launch tower and entered the spacecraft two hours before launch. Once the astronaut was secured inside,

17150-417: The forthcoming Republican National Convention , Eisenhower stated through the Army that he was "not available for and could not accept nomination to high political office"; "life-long professional soldiers", he wrote, "in the absence of some obvious and overriding reason, [should] abstain from seeking high political office". Eisenhower maintained no political party affiliation during this time. Many believed he

17325-544: The funds. They made a pact to take alternate years at college while the other worked to earn the tuitions. Edgar took the first turn at school, and Dwight was employed as a night supervisor at the Belle Springs Creamery. When Edgar asked for a second year, Dwight consented. At that time, a friend Edward "Swede" Hazlett was applying to the Naval Academy and urged Dwight to apply, since no tuition

17500-409: The game six nights a week for five months. Eisenhower continued to play bridge throughout his military career. While stationed in the Philippines, he played regularly with President Manuel Quezon , earning him the nickname the "Bridge Wizard of Manila". An unwritten qualification for an officer's appointment to Eisenhower's staff during World War II was the ability to play bridge. He played even during

17675-461: The goals of the program were to orbit a crewed spacecraft around Earth, investigate the pilot's ability to function in space, and to recover both pilot and spacecraft safely. Existing technology and off-the-shelf equipment would be used wherever practical, the simplest and most reliable approach to system design would be followed, and an existing launch vehicle would be employed, together with a progressive test program. Spacecraft requirements included:

17850-791: The ground and spacecraft during a flight was awarded to the Western Electric Company . Redstone rockets for suborbital launches were manufactured in Huntsville , Alabama, by the Chrysler Corporation and Atlas rockets by Convair in San Diego, California. For crewed launches, the Atlantic Missile Range at Cape Canaveral Air Force Station in Florida was made available by the USAF. This

18025-505: The ground when passing over a ground station, automatically guided by onboard instruments, or manually by the astronaut, who could replace or override the two other methods. Experience validated the astronauts' insistence on manual controls. Without them, Gordon Cooper 's manual reentry during the last flight would not have been possible. The Mercury spacecraft design was modified three times by NASA between 1958 and 1959. After bidding by potential contractors had been completed, NASA selected

18200-468: The ground, with their results (retrofire times and firing attitude) then transmitted to the spacecraft by radio while in flight. All computer systems used in the Mercury space program were housed in NASA facilities on Earth . (See Ground control for details.) The astronaut lay in a sitting position with his back to the heat shield, which was found to be the position that best enabled a human to withstand

18375-409: The ground. Once in orbit, it was not possible for the spacecraft to change its trajectory except by initiating reentry. Each orbit would typically take 88 minutes to complete. The lowest point of the orbit, called perigee , was at about 87 nautical miles (161 km) altitude, and the highest point, called apogee , was about 150 nautical miles (280 km) altitude. When leaving orbit ( E ),

18550-401: The hatch was bolted, the launch area evacuated and the mobile tower rolled back. After this, the launch vehicle was filled with liquid oxygen. The entire procedure of preparing for launch and launching the spacecraft followed a time table called the countdown. It started a day in advance with a pre-count, in which all systems of the launch vehicle and spacecraft were checked. After that followed

18725-432: The hazing, though he willingly accepted it as a plebe. He was also a regular violator of the more detailed regulations and finished school with a less than stellar discipline rating. Academically, Eisenhower's best subject by far was English. Otherwise, his performance was average, though he thoroughly enjoyed the typical emphasis of engineering on science and mathematics. In athletics, Eisenhower later said that "not making

18900-480: The heat of atmospheric reentry . Finally, a parachute slowed the craft for a water landing . Both astronaut and capsule were recovered by helicopters deployed from a US Navy ship. The Mercury project gained popularity, and its missions were followed by millions on radio and TV around the world. Its success laid the groundwork for Project Gemini , which carried two astronauts in each capsule and perfected space docking maneuvers essential for crewed lunar landings in

19075-400: The heat shield to reduce the force of impact ( J ). Upon landing the parachutes were released. An antenna ( K ) was raised and sent out signals that could be traced by ships and helicopters . Further, a green marker dye was spread around the spacecraft to make its location more visible from the air. Frogmen brought in by helicopters inflated a collar around the craft to keep it upright in

19250-616: The help of his brother Milton Eisenhower , then a journalist at the Agriculture Department , he produced a guide to American battlefields in Europe. He then was assigned to the Army War College and graduated in 1928. After a one-year assignment in France, Eisenhower served as executive officer to General George V. Moseley , Assistant Secretary of War , from 1929 to February 1933. Major Eisenhower graduated from

19425-480: The high g-forces of launch and reentry. A fiberglass seat was custom-molded from each astronaut's space-suited body for maximum support. Near his left hand was a manual abort handle to activate the launch escape system if necessary prior to or during liftoff, in case the automatic trigger failed. To supplement the onboard environmental control system, he wore a pressure suit with its own oxygen supply, which would also cool him. A cabin atmosphere of pure oxygen at

19600-561: The improvement of highways became a signature issue for Eisenhower as president. He assumed duties again at Camp Meade , Maryland, commanding a battalion of tanks, where he remained until 1922. His schooling continued, focused on the nature of the next war and the role of the tank. His new expertise in tank warfare was strengthened by a close collaboration with George S. Patton , Sereno E. Brett , and other senior tank leaders. Their leading-edge ideas of speed-oriented offensive tank warfare were strongly discouraged by superiors, who considered

19775-400: The inevitable loss of life and suffering that would be experienced by the troops under his command and their families. This prompted him to make a point of visiting every division involved in the invasion. Eisenhower's sense of responsibility was underscored by his draft of a statement to be issued if the invasion failed. It has been called one of the great speeches of history: Our landings in

19950-484: The interviews, 32 were selected for further physical and mental testing. Their health, vision, and hearing were examined, together with their tolerance to noise, vibrations, g-forces, personal isolation, and heat. In a special chamber, they were tested to see if they could perform their tasks under confusing conditions. The candidates had to answer more than 500 questions about themselves and describe what they saw in different images. Navy Lt (later Capt) Jim Lovell , who

20125-470: The last 20 years of his life. The images were mostly landscapes but also portraits of subjects such as Mamie, their grandchildren, General Montgomery, George Washington , and Abraham Lincoln . Wendy Beckett stated that Eisenhower's paintings, "simple and earnest", caused her to "wonder at the hidden depths of this reticent president". A conservative in both art and politics, Eisenhower in a 1962 speech denounced modern art as "a piece of canvas that looks like

20300-555: The last time an American was launched alone to conduct an entirely solo orbital mission. Cooper later went on to participate in Project Gemini where he once again beat the endurance record during Gemini 5 . Deke Slayton was grounded in 1962 due to a heart condition, but remained with NASA and was appointed senior manager of the Astronaut Office and later additionally assistant director of Flight Crew Operations at

20475-673: The legitimate government of China, and he won congressional approval of the Formosa Resolution . His administration provided major aid to help the French fight off Vietnamese Communists in the First Indochina War . After the French left, he gave strong financial support to the new state of South Vietnam . He supported regime-changing military coups in Iran and Guatemala orchestrated by his own administration. During

20650-412: The mission order, with some capsules being reserved as backup or used in tests. Times given are Coordinated Universal Time , local time + 5 hours. MA = Mercury-Atlas, MR = Mercury-Redstone, LC = Launch Complex. The 20 uncrewed flights used Little Joe, Redstone, and Atlas launch vehicles. They were used to develop the launch vehicles, launch escape system, spacecraft and tracking network. One flight of

20825-689: The mission. Hence he chose James Ord , a classmate of his at West Point. Having been brought up in Mexico, which inculcated into him the Spanish culture which influenced both Mexico and the Philippines, Ord was deemed the right pick for the job. Eisenhower had strong philosophical disagreements with MacArthur regarding the role of the Philippine Army and the leadership qualities that an American army officer should exhibit and develop in his subordinates. The antipathy between Eisenhower and MacArthur lasted

21000-449: The narrow end of the spacecraft contained three parachutes: a drogue to stabilize free fall and two main chutes, a primary and reserve. Between the heat shield and inner wall of the crew compartment was a landing skirt, deployed by letting down the heat shield before landing. On top of the recovery compartment was the antenna section ( 5 ) containing both antennas for communication and scanners for guiding spacecraft orientation. Attached

21175-492: The new tank corps , where he was promoted to brevet lieutenant colonel in the National Army . He commanded a unit that trained tank crews at Camp Colt  – his first command. Though Eisenhower and his tank crews never saw combat, he displayed excellent organizational skills as well as an ability to accurately assess junior officers' strengths and make optimal placements of personnel. His spirits were raised when

21350-477: The new American attitudes of the German people as Nazi victims not villains, while aggressively purging the ex-Nazis. In November 1945, Eisenhower returned to Washington to replace Marshall as Chief of Staff of the Army . His main role was the rapid demobilization of millions of soldiers, which was delayed by lack of shipping. Eisenhower was convinced in 1946 that the Soviet Union did not want war and that friendly relations could be maintained; he strongly supported

21525-669: The new United Nations and favored its involvement in the control of atomic bombs. However, in formulating policies regarding the atomic bomb and relations with the Soviets, Truman was guided by the State Department and ignored Eisenhower and the Pentagon . Indeed, Eisenhower had opposed the use of the atomic bomb against the Japanese, writing, "First, the Japanese were ready to surrender and it wasn't necessary to hit them with that awful thing. Second, I hated to see our country be

21700-467: The new approach too radical and preferred to continue using tanks in a strictly supportive role for the infantry. Eisenhower was even threatened with court-martial for continued publication of these proposed methods of tank deployment, and he relented. From 1920, Eisenhower served under a succession of talented generals – Fox Conner , John J. Pershing , Douglas MacArthur and George Marshall . He first became executive officer to General Conner in

21875-532: The new position of astronaut. During this time, women were banned from flying in the military and so could not successfully qualify as test pilots. This meant that no female candidates could earn consideration for the title of astronaut. Civilian NASA X-15 pilot Neil Armstrong was also disqualified, though he had been selected by the US Air Force in 1958 for its Man in Space Soonest program, which

22050-422: The next goal. The Soviet Union put the first human, cosmonaut Yuri Gagarin , into a single orbit aboard Vostok 1 on April 12, 1961. Shortly after this, on May 5, the US launched its first astronaut, Alan Shepard , on a suborbital flight. Soviet Gherman Titov followed with a day-long orbital flight in August 1961. The US reached its orbital goal on February 20, 1962, when John Glenn made three orbits around

22225-600: The next most difficult campaign against the Germans—a beach landing assault. His first struggles, however, were with Allied leaders and officers on matters vital to the success of the Normandy invasion; he argued with Roosevelt over an essential agreement with De Gaulle to use French resistance forces in covert operations against the Germans in advance of Operation Overlord. Admiral Ernest J. King fought with Eisenhower over King's refusal to provide additional landing craft from

22400-414: The number of candidates at 508. These candidates were USN or USMC naval aviation pilots (NAPs), or USAF pilots of Senior or Command rating . These aviators had long military records, which would give NASA officials more background information on which to base their decisions. Furthermore, these aviators were skilled in flying the most advanced aircraft to date, giving them the best qualifications for

22575-440: The numbering of crewed missions did not start with 1. Also, there were two separately numbered series: MR for "Mercury-Redstone" (suborbital flights), and MA for "Mercury-Atlas" (orbital flights). These names were not popularly used, since the astronauts followed a pilot tradition, each giving their spacecraft a name. They selected names ending with a "7" to commemorate the seven astronauts. Spacecraft production numbers don't match

22750-473: The package could be severed when it was no longer needed. Next to the heat shield was the pressurized crew compartment ( 3 ). Inside, an astronaut would be strapped to a form-fitting seat with instruments in front of him and with his back to the heat shield. Underneath the seat was the environmental control system supplying oxygen and heat, scrubbing the air of CO 2 , vapor and odors, and (on orbital flights) collecting urine. The recovery compartment ( 4 ) at

22925-523: The position of the spacecraft, its ground track and the place it could land in an emergency within the next 30 minutes. Other computers associated with ground control for Mercury included a vacuum-tube-based IBM 709 system in Cape Canaveral which determined whether a mid-launch abort might be needed and where an aborting capsule would land, another IBM 709 in Bermuda which served as backup for

23100-642: The regimental executive officer. In March 1941 he was promoted to colonel and assigned as chief of staff of the newly activated IX Corps under Major General Kenyon Joyce . In June 1941, he was appointed chief of staff to General Walter Krueger , Commander of the Third Army , at Fort Sam Houston in San Antonio, Texas. After successfully participating in the Louisiana Maneuvers , he was promoted to brigadier general on October 3, 1941. After

23275-470: The rest of their lives. Historians have concluded that this assignment provided valuable preparation for handling the challenging personalities of Winston Churchill , George S. Patton, George Marshall, and Bernard Montgomery during World War II. Eisenhower later emphasized that too much had been made of the disagreements with MacArthur and that a positive relationship endured. While in Manila, Mamie suffered

23450-614: The role of Capsule Communicator, or CAPCOM, who communicated with the astronaut in orbit. Data from the spacecraft were sent to the ground, processed at the Goddard Space Center by a redundant pair of transistorized IBM 7090 computers and relayed to the Mercury Control Center at Cape Canaveral. In the Control Center, the data were displayed on boards on each side of a world map, which showed

23625-497: The second Mercury flight as a crude workaround. It would take until the third flight in February 1962 before a dedicated urine collection device was installed. Once in orbit, the spacecraft could be rotated in yaw, pitch, and roll : along its longitudinal axis (roll), left to right from the astronaut's point of view (yaw), and up or down (pitch). Movement was created by rocket-propelled thrusters which used hydrogen peroxide as

23800-413: The selection committee accept him. USAF Capt. (later Col.) Joseph Kittinger , a USAF fighter pilot and stratosphere balloonist, met all the requirements but preferred to stay in his contemporary project. Other potential candidates declined because they did not believe that human spaceflight had a future beyond Project Mercury. From the original 508, 110 candidates were selected for an interview, and from

23975-431: The services of the often unruly George S. Patton, by severely reprimanding him when Patton earlier had slapped a subordinate , and then when Patton gave a speech in which he made improper comments about postwar policy. The D-Day Normandy landings on June 6, 1944, were costly but successful. Two months later (August 15), the invasion of Southern France took place, and control of forces in the southern invasion passed from

24150-413: The shield. The heat sink would remove heat by the flow of the air inside the shock wave, whereas the ablative heat shield would remove heat by a controlled evaporation of the ablative material. After uncrewed tests, the latter was chosen for crewed flights. Apart from the capsule design, a rocket plane similar to the existing X-15 was considered. This approach was still too far from being able to make

24325-429: The spacecraft peaked, making separation of the launch vehicle and spacecraft most difficult. It was also the point at which the astronaut was subjected to the heaviest vibrations. The Little Joe rocket used solid-fuel propellant and was originally designed in 1958 by NACA for suborbital crewed flights, but was redesigned for Project Mercury to simulate an Atlas-D launch. It was produced by North American Aviation . It

24500-428: The spacecraft, the pilot would experience weightlessness as shown on the image. The recovery procedure would be the same as an orbital mission.[AS] Preparations for a mission started a month in advance with the selection of the primary and back-up astronaut; they would practice together for the mission. For three days prior to launch, the astronaut went through a special diet to minimize his need for defecating during

24675-553: The spread of communism and reduce federal deficits . In 1953, he considered using nuclear weapons to end the Korean War and may have threatened China with nuclear attack if an armistice was not reached quickly. China did agree and an armistice resulted, which remains in effect. His New Look policy of nuclear deterrence prioritized "inexpensive" nuclear weapons while reducing funding for expensive Army divisions. He continued Harry S. Truman 's policy of recognizing Taiwan as

24850-657: The stressful weeks leading up to the D-Day landings. His favorite partner was General Alfred Gruenther , considered the best player in the US Army; he appointed Gruenther his second-in-command at NATO partly because of his skill at bridge. Saturday night bridge games at the White House were a feature of his presidency. He was a strong player, though not an expert by modern standards. The great bridge player and popularizer Ely Culbertson described his game as classic and sound with "flashes of brilliance" and said that "you can always judge

25025-425: The subsequent Apollo program announced a few weeks after the first crewed Mercury flight. Project Mercury was officially approved on October 7, 1958, and publicly announced on December 17. Originally called Project Astronaut, President Dwight Eisenhower felt that gave too much attention to the pilot. Instead, the name Mercury was chosen from classical mythology , which had already lent names to rockets like

25200-545: The top of the curve, the spacecraft's retrorockets were fired for testing purposes; they were not necessary for reentry because orbital speed had not been attained. The spacecraft landed in the Atlantic Ocean. The suborbital mission took about 15 minutes, had an apogee altitude of 102–103 nautical miles (189–191 km), and a downrange distance of 262 nautical miles (485 km). From the time of booster-spacecraft separation until reentry where air started to slow down

25375-425: The two IBM 7090 transistor-based machines at Goddard, and a Burroughs-GE system which provided radio guidance for the Atlas during launch. The World Wide Tracking Network went on to serve subsequent space programs, until it was replaced by a satellite relay system in the 1980s. Mission Control Center was moved from Cape Canaveral to Houston in 1965. On April 12, 1961, the Soviet cosmonaut Yuri Gagarin became

25550-671: The unit under his command received orders overseas to France. This time his wishes were thwarted when the armistice was signed a week before his departure date. Completely missing out on the warfront left him depressed and bitter for a time, despite receiving the Distinguished Service Medal for his work at home. In World War II, rivals who had combat service in the Great War (led by Gen. Bernard Montgomery ) sought to denigrate Eisenhower for his previous lack of combat duty, despite his stateside experience establishing

25725-416: The water. The recovery helicopter hooked onto the spacecraft and the astronaut blew the escape hatch to exit the capsule. He was then hoisted aboard the helicopter that finally brought both him and the spacecraft to the ship. The number of personnel supporting a Mercury mission was typically around 18,000, with about 15,000 people associated with recovery. Most of the others followed the spacecraft from

25900-657: Was "one of the most deeply religious men I know" though unattached to any "sect or organization". He was baptized in the Presbyterian Church in 1953. Eisenhower attended Abilene High School and graduated in 1909. As a freshman, he injured his knee and developed a leg infection that extended into his groin, which his doctor diagnosed as life-threatening. The doctor insisted that the leg be amputated but Dwight refused to allow it, and surprisingly recovered, though he had to repeat his freshman year. He and brother Edgar both wanted to attend college, though they lacked

26075-557: Was a flap used to ensure the spacecraft was faced heat shield first during reentry. A launch escape system ( 6 ) was mounted to the narrow end of the spacecraft containing three small solid-fueled rockets which could be fired briefly in a launch failure to separate the capsule safely from its booster. It would deploy the capsule's parachute for a landing nearby at sea. (See also Mission profile for details.) The Mercury spacecraft did not have an on-board computer, instead relying on all computation for reentry to be calculated by computers on

26250-500: Was able to manually control the spacecraft's attitude. He quit NASA in 1964, when he came to the conclusion that he likely would not be selected for any Apollo missions, and was later elected to the US Senate, serving from 1974 to 1999. During his tenure, he returned to space in 1998 as a Payload Specialist aboard STS-95 . Scott Carpenter was the second astronaut in orbit and flew on Mercury-Atlas 7 on May 24, 1962. The spaceflight

26425-705: Was also the site of the Mercury Control Center while the computing center of the communication network was in Goddard Space Center , Maryland. Little Joe rockets were launched from Wallops Island , Virginia. Astronaut training took place at Langley Research Center in Virginia, Lewis Flight Propulsion Laboratory in Cleveland, Ohio, and Naval Air Development Center Johnsville in Warminster, PA. Langley wind tunnels together with

26600-582: Was appointed Assistant Chief of Staff in charge of the new Operations Division (which replaced WPD) under Chief of Staff General George C. Marshall, who spotted talent and promoted accordingly. At the end of May 1942, Eisenhower accompanied Lt. Gen. Henry H. Arnold , commanding general of the Army Air Forces , to London to assess the effectiveness of the theater commander in England, Maj. Gen. James E. Chaney . He returned to Washington on June 3 with

26775-511: Was born in Denison, Texas , and raised in Abilene, Kansas . His family had a strong religious background, and his mother became a Jehovah's Witness . Eisenhower, however, belonged to no organized church until 1952. He graduated from West Point in 1915 and later married Mamie Doud , with whom he had two sons. During World War I , he was denied a request to serve in Europe and instead commanded

26950-411: Was built up at lift-off ( A ). After 30 seconds of flight, the point of maximum dynamic pressure against the vehicle was reached, at which the astronaut felt heavy vibrations. After 2 minutes and 10 seconds, the two outboard booster engines shut down and were released with the aft skirt, leaving the center sustainer engine running ( B ). At this point, the launch escape system was no longer needed, and

27125-450: Was charged in these positions with planning and carrying out the Allied assault on the coast of Normandy in June 1944 under the code name Operation Overlord, the liberation of Western Europe and the invasion of Germany. Eisenhower, as well as the officers and troops under him, had learned valuable lessons in their previous operations, and their skills had all strengthened in preparation for

27300-492: Was deemed necessary to the campaign and Eisenhower encountered a "preposterous situation" with the multiple rival factions in France. His primary objective was to move forces successfully into Tunisia and intending to facilitate that objective, he gave his support to François Darlan as High Commissioner in North Africa, despite Darlan's previous high offices in Vichy France and his continued role as commander-in-chief of

27475-543: Was essentially a repeat of Mercury-Atlas 6, but a targeting error during re-entry took Aurora 7 250 miles (400 km) off-course, delaying recovery. Afterwards, he joined the Navy's "Man in the Sea" program and is the only American to be both an astronaut and an aquanaut . Carpenter's Mercury flight was his only trip into space. Wally Schirra flew aboard Sigma 7 on Mercury-Atlas 8 on October 3, 1962. The mission's main goal

27650-663: Was extended as commander of AFHQ across the Mediterranean basin to include the British Eighth Army , commanded by General Sir Bernard Montgomery. The Eighth Army had advanced across the Western Desert from the east and was ready for the start of the Tunisia Campaign . After the capitulation of Axis forces in North Africa, Eisenhower oversaw the invasion of Sicily . Once Mussolini ,

27825-454: Was given a name ending with a "7" by its pilot. The Space Race began with the 1957 launch of the Soviet satellite Sputnik 1 . This came as a shock to the American public, and led to the creation of NASA to expedite existing US space exploration efforts, and place most of them under civilian control. After the successful launch of the Explorer 1 satellite in 1958, crewed spaceflight became

28000-765: Was in charge of training at Fort Oglethorpe in Georgia , his wife Mamie had their first son, Doud Dwight "Icky" Eisenhower , who died of scarlet fever at the age of three. Eisenhower was mostly reluctant to discuss his death. Their second son, John Eisenhower , was born in Denver , Colorado. John served in the United States Army , retired as a brigadier general, became an author and served as Ambassador to Belgium from 1969 to 1971. He married Barbara Jean Thompson and had four children: David , Barbara Ann, Susan Elaine and Mary Jean . David, after whom Camp David

28175-465: Was included for the Mercury astronauts. An inquiry on the subject was made in February 1961 by a student, but NASA responded by stating that "the first space man is not expected to have 'to go". The expected short flight times meant that this was overlooked, although after Alan Shepard had a launch delay of four hours, he was forced to urinate in his suit, short-circuiting some of the electrodes monitoring his vital signs. Gus Grissom wore two rubber pants on

28350-453: Was later an astronaut in the Gemini and Apollo programs , did not pass the physical tests. After these tests it was intended to narrow the group down to six astronauts, but in the end it was decided to keep seven. The astronauts went through a training program covering some of the same exercises that were used in their selection. They simulated the g-force profiles of launch and reentry in

28525-512: Was no protocol for selecting astronauts, so NASA would set a far-reaching precedent with both their selection process and initial choices for astronauts. At the end of 1958, various ideas for the selection pool were discussed privately within the national government and the civilian space program, and also among the public at large. Initially, there was the idea to issue a widespread public call to volunteers. Thrill-seekers such as rock climbers and acrobats would have been allowed to apply, but this idea

28700-528: Was not able to change direction; instead its flight depended on the angle from which it was launched. Its maximum altitude was 100 mi (160 km) fully loaded. A Scout launch vehicle was used for a single flight intended to evaluate the tracking network; however, it failed and was destroyed from the ground shortly after launch. The Mercury-Redstone Launch Vehicle was an 83-foot-tall (25 m) (with capsule and escape system) single-stage launch vehicle used for suborbital ( ballistic ) flights. It had

28875-604: Was offered a post by the Philippine Commonwealth Government, namely by then Philippine President Manuel L. Quezon on recommendations by MacArthur, to become the chief of police of a new capital being planned, now named Quezon City , but he declined the offer. Eisenhower returned to the United States in December 1939 and was assigned as commanding officer of the 1st Battalion, 15th Infantry Regiment at Fort Lewis , Washington, later becoming

29050-552: Was produced by North American Aviation and its direction could be altered during flight by its fins. They worked in two ways: by directing the air around them, or by directing the thrust by their inner parts (or both at the same time). Both the Atlas-D and Redstone launch vehicles contained an automatic abort sensing system which allowed them to abort a launch by firing the launch escape system if something went wrong. The Jupiter rocket, also developed by Wernher von Braun 's team at

29225-415: Was quickly shot down by NASA officials who understood that an undertaking such as space flight required individuals with professional training and education in flight engineering. By late 1958, NASA officials decided to move forward with test pilots being the heart of their selection pool. On President Eisenhower's insistence, the group was further narrowed down to active duty military test pilots , which set

29400-421: Was recovered from the bottom of the Atlantic Ocean after 38 years. Some spacecraft were modified after initial production (refurbished after launch abort, modified for longer missions, etc.). A number of Mercury boilerplate spacecraft (made from non-flight materials or lacking production spacecraft systems) were also made by NASA and McDonnell. They were designed and used to test spacecraft recovery systems and

29575-400: Was remorseful for the remainder of his life. Eisenhower developed a keen and enduring interest in exploring the outdoors. He learned about hunting and fishing, cooking, and card playing from a man named Bob Davis who camped on the Smoky Hill River . While his mother was against war, it was her collection of history books that first sparked Eisenhower's interest in military history; he became

29750-428: Was replaced by Mercury. Although Armstrong had been a combat-experienced NAP during the Korean War, he left active duty in 1952. Armstrong became NASA's first civilian astronaut in 1962 when he was selected for NASA's second group, and became the first man on the Moon in 1969. It was further stipulated that candidates should be between 25 and 40 years old, no taller than 5 ft 11 in (1.80 m), and hold

29925-410: Was required. Eisenhower requested consideration for either Annapolis or West Point with his Senator, Joseph L. Bristow . Though Eisenhower was among the winners of the entrance-exam competition, he was beyond the age limit for the Naval Academy. He accepted an appointment to West Point in 1911. At West Point, Eisenhower relished the emphasis on traditions and on sports, but was less enthusiastic about

30100-400: Was separated from the spacecraft by its jettison rocket ( C ). The space vehicle moved gradually to a horizontal attitude until, at an altitude of 87 nautical miles (161 km), the sustainer engine shut down and the spacecraft was inserted into orbit ( D ). This happened after 5 minutes and 10 seconds in a direction pointing east, whereby the spacecraft would gain speed from the rotation of

30275-407: Was shot down over the Soviet Union. Eisenhower approved the Bay of Pigs Invasion , which was left to John F. Kennedy to carry out. On the domestic front, Eisenhower governed as a moderate conservative who continued New Deal agencies and expanded Social Security . He covertly opposed Joseph McCarthy and contributed to the end of McCarthyism by openly invoking executive privilege . He signed

30450-444: Was the 34th president of the United States , serving from 1953 to 1961. During World War II , he was Supreme Commander of the Allied Expeditionary Force in Europe and achieved the five-star rank as General of the Army . Eisenhower planned and supervised two of the most consequential military campaigns of World War II : Operation Torch in the North Africa campaign in 1942–1943 and the invasion of Normandy in 1944. Eisenhower

30625-456: Was to show development of environmental controls or life-support systems that would allow for safety in space, thus being a flight mainly focused on technical evaluation, rather than scientific experimentation. The mission lasted 9 hours and 13 minutes, setting a new U.S. flight duration record. In December 1965, Schirra flew on Gemini 6A , achieving the first ever space rendezvous with sister spacecraft Gemini 7 . Three years later, he commanded
