Soviet Union launched
Sputnik 1, the first artificial
satellite. This shattered Americans' confidence in their technological superiority, creating a wave of anxiety known as the
Sputnik crisis. Among his responses,
President Dwight D. Eisenhower launched the
Space Race. The
National Aeronautics and Space Administration (NASA) was established on October 1, 1958, as a civilian agency to develop space technology. One of its first initiatives was
Project Mercury, which aimed to launch a man into
Earth orbit, evaluate his capabilities in space, and return him safely to the Earth. The first
astronaut intake was drawn from the ranks of military test pilots. The service records of 508 graduates of test pilot schools were obtained from the
Department of Defense. Of these, 110 met the minimum standards: the candidates had to be younger than 40, possess a bachelor's degree or equivalent and to be or less. While these were not all strictly enforced, the height requirement was firm, owing to the size of the Project Mercury spacecraft. DPP was restricted to those with
bachelor's degrees, so it was assumed that Carpenter had one. On February 2, 1959, the first 35 candidates went to
The Pentagon, where they met with the
Chief of Naval Operations,
Admiral Arleigh Burke, and the
Chief of Staff of the United States Air Force,
General (United States) Thomas D. White, who assured them that the services would support them if they volunteered to become astronauts, and that their professional progress and promotions would not be affected. The number of candidates was reduced to 32, which the NASA selection panel considered to be an adequate number from which to select 12 astronauts. The degree of interest also indicated that far fewer would drop out during training than anticipated, which would result in training astronauts who would not be required to fly Project Mercury missions. It was therefore decided to halve the number of astronauts. . Left to right:

Lovelace Clinic and the
Wright Aerospace Medical Laboratory. Carpenter had the lowest body fat, scored highest on the treadmill and cycling tests, and was able to hold his breath the longest. This was despite the fact that he had smoked a pack of cigarettes a day since joining the Navy in 1943, and did not quit smoking until 1985. NASA's
Charles J. Donlan called Carpenter's home on April 3, 1959, to inform him that he had been one of the seven men selected. Rene answered; Carpenter was on
Hornet, but she could reach him. Carpenter called Donlan from a wharfside pay phone to accept the offer, but
Hornet skipper,
Captain Marshall W. White, refused to release him. Donlan called Burke, who contacted White and promised to send him another intelligence officer, but told him that the country needed Carpenter for the NASA assignment. The identities of the seven were announced at a press conference at
Dolley Madison House in Washington, D.C., on April 9, 1959: Carpenter,
Gordon Cooper,
John Glenn,
Gus Grissom,
Wally Schirra,
Alan Shepard, and
Deke Slayton. The magnitude of the challenge ahead of them was made clear a few weeks later, on the night of May 18, 1959, when the seven astronauts gathered at
Cape Canaveral to watch their first rocket launch, of an
SM-65D Atlas, which was similar to the one that would carry them into orbit. A few minutes after liftoff, it spectacularly exploded, lighting up the night sky. The astronauts were stunned. Shepard turned to Glenn and said: "Well, I'm glad they got that out of the way."
Mercury-Atlas 7 on the morning of the flight of
Mercury Atlas 7.
Mission Carpenter, along with the other six Mercury astronauts, participated in the development of the Mercury spacecraft. Each had a specialty; Carpenter's was the onboard navigational equipment. He served as backup pilot on
Mercury-Atlas 6 for Glenn, who flew the first U.S. orbital mission aboard
Friendship 7 in February 1962. Carpenter, serving as
capsule communicator on this flight, can be heard saying "Godspeed, John Glenn" on the recording of Glenn's liftoff. The next mission, a second crewed orbital flight, was to be flown by Slayton in a spacecraft he would have named
Delta 7, but Slayton was suddenly grounded for an
atrial fibrillation. Carpenter was assigned to replace him instead of Slayton's backup, Schirra, as Carpenter had more training time in the simulators. In contrast to Glenn's flight,
Mercury-Atlas 7 was planned as a scientific mission rather than an engineering one. After the most trouble-free countdown of Project Mercury to date, Carpenter flew into space on May 24, 1962, watched by 40 million television viewers. He performed five onboard experiments per the flight plan, and became the first American astronaut to eat solid food in space. He also identified the mysterious "fireflies" observed by Glenn during
Friendship 7 as particles of frozen liquid loosened from the outside of the spacecraft, which he could produce by rapping on the wall near the window. He renamed them "frostflies". '' spacecraft on May 24, 1962. Unnoticed by ground control or the pilot, an overexpenditure of fuel was caused by an intermittently malfunctioning pitch horizon scanner (PHS). Still, NASA later reported that Carpenter had: At the retrofire event, the PHS malfunctioned once more, forcing Carpenter to manually control his
reentry. This caused him to overshoot the planned
splashdown point in the Atlantic Ocean by . The PHS malfunction yawed the spacecraft 25 degrees to the right, accounting for of overshoot; the delay caused by the automatic sequencer required Carpenter to fire the retrorockets manually. This effort took two pushes of the override button and accounted for another 15 to of overshoot. The thrusters had a set ignition sequence, and this sequence was delayed by Carpenter manually firing them. This added another , producing a overshoot. Had Carpenter not assumed manual control, the overshoot would have been greater still. The spacecraft splashed down at 19°27'N, 63°59'W, about north of
Anegada in the
British Virgin Islands. The flight lasted 4 hours and 56 minutes, during which
Aurora 7 had attained a maximum altitude of and an orbital velocity of and traveled .
Recovery There was a great deal of public concern over whether Carpenter had survived. Broadcasting from a
CBS news van in Florida,
Walter Cronkite painted a grim picture. Although
Aurora 7s Search And Rescue And Homing (SARAH) beacon broadcast its precise location, and the recovery vessels, the
aircraft carrier and the
destroyer , were on their way, NASA did not pass this information along to the news media. Cronkite reported that "while thousands watch and pray, certainly here at Cape Canaveral, the silence is almost intolerable." Knowing that the recovery vessels might take some time to get to him, and aware of the danger of
Aurora 7 foundering, as had happened to Grissom's
Liberty Bell 7, Carpenter made his way out through the neck of the spacecraft, something the less agile Glenn had been unable to do. He inflated his life raft, climbed into it, and awaited rescue. The sea around him was stained with green dye released to attract the rescue helicopter. The life raft had no radio. About 36 minutes after splashdown, Carpenter spotted two aircraft. A P2V Neptune from
Patrol Squadron 18 flying out of
Naval Air Station Jacksonville was the first to sight and mark Carpenter's position. It was followed by a
Piper Apache, which circled and photographed. Carpenter then knew he had been located. They were followed by
SC-54 Skymaster aircraft, one of which parachuted two frogmen,
Airman First Class John F. Heitsch and
Sergeant Ray McClure, while another dropped a flotation collar that the frogmen attached to
Aurora 7. A radio battery was dropped, but not the radio. An Air Force
SA-16 Albatross arrived to collect them, but NASA Mission Control forbade it for fear that the seaplane might break up, although the crew did not consider the swell dangerous. After three hours, Carpenter was picked up by a
HSS-2 Sea King helicopter, which took him to
Intrepid, while
Aurora 7 was recovered by
John R. Pierce.
Postflight Postflight analysis described the PHS malfunction as "mission critical" but noted that the pilot "adequately compensated" for "this anomaly ... in subsequent inflight procedures," confirming that backup systems—human pilots—could succeed when automatic systems fail. Organizational tensions between the astronaut office and the flight controller office and simmering resentment among the latter of the astronauts' hero status—account for much of the criticism of Carpenter's performance during his flight. NASA's 1989 official history of Project Mercury says that until the third pass over Hawaii,
Christopher C. Kraft Jr. (who directed the flight from Cape Canaveral) "considered this mission the most successful to date; everything had gone perfectly except for some overexpenditure of hydrogen peroxide fuel". However, then problems occurred. Kraft wrote in his 2001 memoir: "He was completely ignoring our request to check his instruments... I swore an oath that Scott Carpenter would never again fly in space." Kraft went so far as to name the chapter of his memoirs dealing with Carpenter's flight "The Man Malfunctioned". Yet fuel consumption and other aspects of the vehicle operation were, during Project Mercury, as much if not more the responsibility of the ground controllers.
Gene Kranz, assistant flight director at the time, acknowledged that and placed some of the blame on the shoulders of ground control: "A crewman distracted and behind in the flight plan is a danger to the mission and himself. ... The ground had waited too long in addressing the fuel status and should have been more forceful in getting on with the checklists." In a 2001 letter to
The New York Times written in response to a review of Kraft's memoir, Carpenter wrote: "One might argue," wrote
Tom Wolfe, "that Carpenter had mishandled the reentry, but to accuse him of
panic made no sense in light of the telemetered data concerning his heart rate and his respiratory rate." Schirra would later experience problems with the override button on the subsequent
Mercury-Atlas 8 flight. Some memoirs, such as that of
Gene Cernan, revived the controversy over who or what, exactly, was to blame for the overshoot, suggesting, for example, that Carpenter was distracted by the science and engineering experiments dictated by the flight plan and by the well-reported fireflies phenomenon: ==Ocean research==
