Researching Alan Shepard

A graduate of the United States Naval Academy at Annapolis, Shepard saw action with the surface navy during World War II. He became a naval aviator in 1946, and a test pilot in 1950. He was selected as one of the original NASA Mercury Seven astronauts in 1959, and in May 1961 he made the first crewed Project Mercury flight, Mercury-Redstone 3, in a spacecraft he named Freedom 7. His craft entered space, but was not capable of achieving orbit. He became the second person, and the first American, to travel into space, and the first space traveler to manually control the orientation of his craft. In the final stages of Project Mercury, Shepard was scheduled to pilot the Mercury-Atlas 10 (MA-10), which was planned as a three-day mission. He named Mercury Spacecraft 15B Freedom 7 II in honor of his first spacecraft, but the mission was canceled.

Shepard was designated as the commander of the first crewed Project Gemini mission, but was grounded in 1963 due to Ménière's disease, an inner-ear ailment that caused episodes of extreme dizziness and nausea. This was surgically corrected in 1969, and in 1971, Shepard commanded the Apollo 14 mission, piloting the Apollo Lunar Module Antares. At age 47, he became the fifth, the oldest, and the earliest-born person to walk on the Moon, and the only one of the Mercury Seven astronauts to do so. During the mission, he hit two golf balls on the lunar surface.

Shepard was Chief of the Astronaut Office from November 1963 to July 1969 (the approximate period of his grounding), and from June 1971 until his retirement from the United States Navy and NASA on August 1, 1974. He was promoted to rear admiral on August 25, 1971, the first astronaut to reach that rank.
