Shepard, Alan Shepard, Alan Bartlett Shepard Jr.(noun)
astronaut who made the first United States' suborbital rocket-powered flight in 1961 (1923-1998)
Alan Bartlett Shepard, Jr. was an American naval aviator, test pilot, flag officer, NASA astronaut, and businessman, who in 1961 became the second person, and the first American, to travel into space. This Mercury flight was designed to enter space, but not to achieve orbit. Ten years later, at age 47 the oldest astronaut in the program, Shepard commanded the Apollo 14 mission, piloting the lander to the most accurate landing of the Apollo missions. He became the fifth person to walk on the Moon, and the only astronaut of the Mercury Seven to walk on the Moon. During the mission he hit two golf balls on the lunar surface. These were his only two space flights, as his flight status was interrupted for five years during the Mercury and Gemini programs by Ménière's disease, an inner-ear disease that was surgically corrected before his Moon flight. Shepard served as Chief of the Astronaut Office from November 1963 – July 1969, and from June 1971 – August 1, 1974. He was promoted from Captain to Rear Admiral on August 25, 1971. He retired from the U.S. Navy and NASA in 1974.
