Alan B. Shepard, Jr. (born November 18, 1923, East Derry, New Hampshire, U.S.—died July 21, 1998, Monterey, California) was the first U.S. astronaut to travel in space.

Shepard graduated from the U.S. Naval Academy, Annapolis, Maryland, in 1944 and served in the Pacific during World War II onboard the destroyer Cogswell. He earned his naval aviator wings in 1947, qualified as a test pilot in 1951, and experimented with high-altitude aircraft, in-flight fueling systems, and landings on angled carrier decks. In 1957 he graduated from the Naval War College, Newport, Rhode Island. In 1959 he became one of the original seven astronauts chosen for the U.S. Mercury program by the National Aeronautics and Space Administration (NASA).

On May 5, 1961, Shepard made a 15-minute suborbital flight in the Freedom 7 spacecraft, which reached an altitude of 115 miles (185 km). The flight came 23 days after Soviet cosmonaut Yuri Gagarin became the first human to travel in space, but Shepard’s flight energized U.S. space efforts and made him a national hero.

Shepard was selected as command pilot for the first manned Gemini mission, Gemini 3, but he was grounded in 1964 because of Ménière disease, an ailment that affects the inner ear. In 1969 he underwent corrective surgery that allowed him to return to full flight status.

Shepard commanded the Apollo 14 flight (January 31–February 9, 1971; with Stuart A. Roosa and Edgar D. Mitchell), which involved the first landing in the lunar Fra Mauro highlands. Near the end of his Moon walk, Shepard—an avid golfer—swung at two golf balls with a makeshift six-iron club as a playful demonstration for live television cameras of the weak lunar gravity.

Shepard headed NASA’s astronaut office from 1963 to 1969 and then from 1971 to 1974, when he retired from the navy as a rear admiral and from the space program to undertake a career in private business in Texas. He received numerous awards, including the NASA Distinguished Service Medal and the Congressional Space Medal of Honor. He also coauthored, with fellow Mercury astronaut Deke Slayton, Moon Shot: The Inside Story of America’s Race to the Moon (1994).

Malcolm Scott Carpenter
Born:
May 1, 1925, Boulder, Colorado, U.S.
Died:
October 10, 2013, Denver, Colorado (aged 88)

Scott Carpenter (born May 1, 1925, Boulder, Colorado, U.S.—died October 10, 2013, Denver, Colorado) was an American test pilot and astronaut who was one of the original seven astronauts in NASA’s Project Mercury and the fourth to be launched into space. As the second U.S. astronaut to make an orbital spaceflight, he circled Earth three times on May 24, 1962, in Aurora 7.

Carpenter studied aeronautical engineering at the University of Colorado but left just short of graduation. He entered the U.S. Navy in 1949 and served as a surveillance pilot in the Korean War. He later became a navy test pilot, and he attended the Navy Air Intelligence School in the late 1950s.

NASA selected him as a Mercury astronaut in April 1959. He directed part of the 1962 flight by manual control. It was initially feared that he had not survived the capsule’s atmospheric reentry, but after a 40-minute search it was discovered that he had splashed down in the Atlantic Ocean more than 400 km (about 250 miles) from his projected location. In 1964 he broke his left arm in a motorcycle accident. The resultant inability to rotate his arm properly forced his removal from spaceflight status.

In 1965 Carpenter was detached from the space program to lead two teams in the Sealab II experiment, living and working 205 feet (62.5 metres) under the Pacific Ocean as part of the U.S. Navy’s effort to find better rescue methods for submarines. In 1967 he helped set up Sealab III but retired from naval duty in 1969 to enter private oceanography and energy research.
