There were several unmanned rocket and missile tests that were "suborbital" as early as 1957, pushing payloads into high altitudes. Later tests lofted monkeys and chimps briefly into space. The first MANNED suborbital flight for the US was the Freedom 7 capsule piloted by US Navy CDR Alan B. Shepard (1923-1998) on May 5, 1961. The Mercury-Redstone 3 rocket did not provide the necessary thrust for Shepard to achieve a complete orbit of the Earth, as the USSR's Yuri Gagarin had done three weeks earlier. CDR Shepard (later RADM) had one other space "first". Commanding the Apollo 14 lunar mission ten years later in 1971, he was the first person to ever hit a Golf ball on the moon.

US Navy pilot and astronaut Alan Shepard (1923-1998) became the first US man in space when he flew a suborbital rocket flight in his Freedom 7 spacecraft on May 5, 1961. He flew approximately 303 miles in the 15-minute flight, reaching a maximum altitude of 116.5 miles.
The second American in space was Virgil Grissom, on the 21st of July, 1961. This was the second American 'suborbital' flight, where true space was entered, but the pilot did not make a full orbit of the planet.
John Glenn made America's first orbital flight on February 20,1962. The Russians beat us to it, but John Glenn was the first astronaut.
US astronaut Alan Shepard (1923-1998) was 47 when he walked on the Moon as part of the Apollo 14 mission (February 1971). He was the "first astronaut in space" for the US during his suborbital flight in February 1962, as well as the first man to play golf on the Moon.
The first US satellite was Explorer I, launched on January 31, 1958.The first US manned flights were part of Project Mercury, which included a flight by a chimpanzee named Ham. In 1961, there were suborbital (up and back down) flights by Alan Shepard on May 5, 1961, and by Gus Grissom on July 21, 1961. Flight delays meant that these came after Yuri Gagarin's orbital flight for the USSR (April 12, 1961).The first orbital flight for the US was by John Glenn on February 20, 1962. He made three orbits during a five-hour flight.
Russians Went to Space FirstThe US space program (under NASA and the military branches) were competing with the space program in the Soviet Union (Russia). The Russians launched the first manned spacecraft (with cosmonaut Yuri Gagarin) into orbit on April 12, 1961. The US Mercury program launched two suborbital flights into space (Alan Shepard and then Gus Grissom) on May 5 and July 21, 1961, but did not achieve an orbital flight (with John Glenn) until February 20, 1962.
Design and building of the US space shuttle began in the 1970's, and after many delays the first flight was in 1981.
The first US man in space was John Glen in Friendship 7. He orbitted the earth in space but never went out into space. But the first man technically considered to be put in space by the US was Alan Shepard aboard the Freedom 7 on a sub-orbital flight. Hope this helps.
The first American in space was Alan Shepard, who spent 15 minutes in a sub-orbital flight on May 5, 1961.
The united states launched the space race after Sputnik was launched by the Soviets. President Dwight Eisenhower was the one to take the initiative to have kids get a good education to start the program of NASA created in the late 50s.
