60 Years Ago: Alan Shepard Becomes the First American in Space

In 1961, the United States and the Soviet Union found themselves in a race to put the first human being into space. The United States initiated Project Mercury in 1958 to put the first American into space and selected its first group of astronauts in 1959 to begin training for that mission. The Soviets kept their plans secret but began their own human spaceflight program and selected their own team of 20 cosmonauts in 1960. The Soviets won the race in April 1961 when cosmonaut Yuri A. Gagarin completed a single orbit around the Earth aboard his Vostok capsule. On May 5, 1961, Alan B. Shepard became the first American in space during a suborbital flight aboard his Mercury capsule named Freedom 7. Three weeks later, based on the success of Shepard’s brief flight, President John F. Kennedy committed the United States to achieving a lunar landing before the end of the decade.

The Space Task Group (STG) at NASA’s Langley Research Center in Hampton, Virginia, initiated Project Mercury in 1958 with three goals: orbiting a crewed spacecraft, investigating man’s ability to function in space, and safely recovering both spacecraft and crew member. NASA contracted the McDonnell Aircraft Corporation of St Louis to build the Mercury spacecraft. Initial plans called for up to seven early suborbital flights launched on Redstone rockets to test the single-seat spacecraft, followed by Earth orbital missions using the more powerful Atlas booster. After some early launch failures, the first successful test flight of the Mercury spacecraft without an astronaut on board took place in December 1960, launched on a suborbital flight atop a Redstone rocket.

In parallel with Mercury spacecraft development, NASA selected its first group of astronauts on April 9, 1959. The group consisting of M. Scott Carpenter, L. Gordon Cooper, John H. Glenn, Virgil I. “Gus” Grissom, Walter M. Schirra, Alan B. Shepard, and Donald K. “Deke” Slayton called themselves the Mercury 7 astronauts. They began intensive training in the hope of becoming the first human in space. On Jan. 19, 1961, STG leader Robert R. Gilruth informed the group that Shepard would fly the first suborbital mission, Grissom the second, with Glenn serving as a back up to both of them. To the public, NASA revealed only that one of the three men would make the first flight, with the actual individual made known only close to the launch. Before the first astronaut flight, NASA tested the Redstone rocket and the Mercury capsule by flying chimpanzee Ham on an identical suborbital mission on Jan. 31. Although the flight was mostly successful and the U.S. Navy recovered Ham in excellent shape, a problem with an electrical relay in the Redstone rocket caused NASA to schedule another uncrewed test flight on March 24. That successful flight cleared the way for the flight of the first American astronaut. But on April 12, the Soviets stole the prize by launching cosmonaut Yuri A. Gagarin aboard his Vostok capsule, in which he completed a single orbit around the Earth.

After hundreds of hours of training in simulators, and three simulations inside the capsule itself, Shepard and his backups Grissom and Glenn prepared for the actual flight. Inclement weather scrubbed the first launch attempt on May 2, 1961, and NASA decided it was time to announce that Shepard would indeed be making the first flight. On May 5, the weather proved more cooperative and Shepard climbed aboard Freedom 7 atop the Redstone rocket poised on Launch Pad 5 at the Cape Canaveral Air Force Station, now the Cape Canaveral Space Force Station, in Florida. Half a million people had gathered on nearby beaches to watch the launch in person. An estimated 45 million Americans anxiously watched the liftoff on live television, including President Kennedy at the White House. After more than two hours of delays due to technical issues, the rocket engine ignited at 9:34 a.m. Eastern time, propelling Shepard skyward and into the history books.

During the mission, Shepard communicated with the Mercury Control Center (MCC) at Cape Canaveral. Flight Director Christopher C. Kraft designed the control center to monitor every aspect of the mission. Fellow astronaut Slayton served as the capsule communicator, or capcom, speaking directly with Shepard in Freedom 7. The Redstone rocket’s engine shutoff as planned 2 minutes, 22 seconds after liftoff, with the launch escape tower jettisoning immediately thereafter. After another 10 seconds, the spacecraft separated from the booster, and Shepard began to experience weightlessness. At 3 minutes 10 seconds into the flight, Shepard took over manual control of the spacecraft’s attitude and found that he could control Freedom 7’s orientation with remarkable ease and precision. He conducted visual observations of the Earth below and took some photographs of the cloud-covered Atlantic Ocean. At 5 minutes, 11 seconds, Freedom 7 reached the highest point of its ballistic flight at 116 miles and began descending toward the Earth. Fifteen seconds later the retro-fire maneuver took place. At an altitude of 230,000 feet, Freedom 7 encountered the top layers of the Earth’s atmosphere, ending Shepard’s time in weightlessness after five minutes. During the deceleration, he experienced g-loads of up to 11 times the force of Earth’s gravity, but only for a few seconds. A drogue parachute deployed at 22,000 feet to slow and stabilize the spacecraft, followed by the main parachute at 10,000 feet. A landing bag deployed at the bottom of the spacecraft to further cushion the impact, and after a flight of 15 minutes 22 seconds, Freedom 7 splashed down in the Atlantic Ocean north of the Bahama Islands and 300 miles southeast of Cape Canaveral, completing Shepard’s flight as the first American in space.

Freedom 7 splashed down just four miles from the prime recovery ship – an aircraft carrier called the U.S.S. Lake Champlain (CVS-39). Recovery forces deployed from the Lake Champlain and retrieved Shepard and his capsule within 20 minutes of splashdown and delivered them onto the flight deck. Shepard went below decks for a brief medical exam and a congratulatory phone call from President Kennedy. At a press conference afterward, the President hinted that he would soon be seeking more funding for a greatly expanded space program. Less than two and a half hours after arriving aboard the Lake Champlain, Shepard boarded a plane that took him the Grand Bahama Island for more in-depth medical examinations. Meanwhile, a helicopter retrieved Freedom 7 from the Lake Champlain and delivered it to Cape Canaveral. After initial inspections, the capsule traveled to Paris to go on exhibit May 25 at the International Aeronautical Show.

On May 8, 1961, Shepard arrived at the White House where in a ceremony in the Rose Garden President Kennedy presented him with NASA’s highest award, the Distinguished Service Medal. From there, Shepard with his wife Louise riding in Vice President Lyndon B. Johnson’s limousine took part in a motorcade that took them to the Capitol for a reception with lawmakers. On May 25, President Kennedy returned to the Capitol to address a joint session of Congress. During the speech, he stated that the United States should “commit itself to achieve the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth.” That risky commitment, based on a single 15-minute suborbital spaceflight, culminated with the landing on the Moon of Apollo 11 on July 20, 1969.
