The story of how the first American went to space

As NASA fought to catch up to the Soviet Union in the space race, they selected a Navy veteran as the first astronaut. But what happened once Alan Shepard stepped into the space capsule?

When a Redstone rocket lifted the spacecraft Freedom 7 into the sky on May 5, 1961, there was more resting on pilot Alan Shepard’s shoulders than just 6 g’s of acceleration. The outcome of his mission could decide the future of the American space program. The United States and its rival, the Soviet Union, were in a race to conquer outer space and the U.S. was losing. In 1957, the U.S.S.R. had shocked the world by launching the satellite Sputnik 1 into orbit. From that moment, the U.S. was scrambling to catch up. The next year, President Dwight D. Eisenhower and his administration created the National Aeronautics and Space Administration (NASA), which in turn launched Project Mercury, with the goal of sending an American into space by 1960. The seven test pilots picked to train for the mission became known as the Mercury 7; among them were John Glenn and Alan Shepard, who became friends and rivals as they competed for the first assignment. However, they were both denied the coveted title of first man in space. On April 12, 1961, Soviet cosmonaut Yuri Gagarin blasted off in Vostok 1, orbited the Earth, and landed safely.

Gagarin’s triumph propelled the space race into overdrive. On May 2, NASA announced its inaugural astronaut: the lanky, 37-year-old Navy veteran, Shepard. After weather delays, on May 5 Shepard donned his pressure suit and squeezed himself into the tiny Mercury capsule, a craft that could fit easily into a modern garage. But as it turned out, NASA hadn’t foreseen everything. Lying on his back, strapped into his seat and facing an array of switches and dials, Shepard realized that his bladder was full. He was told he couldn’t get out of the capsule. So, as Shepard recalled later, he had no choice but to pee into his long cotton underwear and focus on the next steps.

At 9:34 a.m., the rocket ignited and Freedom 7 lifted into the air. As some 45 million people watched the event on television, the capsule detached from its booster and soared to 116 miles above the planet. In his brief time aloft, Shepard became weightless, practiced controlling the spacecraft manually, and photographed the Atlantic Ocean before splashdown.

Shepard’s suborbital flight took only 15 minutes and 22 seconds, but the die was cast. On May 25, President Kennedy announced a major expansion of the U.S. space program. “I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the Earth,” he said. Just over eight years later, Apollo 11 touched down on the lunar surface.
