On February 20, 1962, John Glenn became the first American astronaut to orbit Earth. This remarkable achievement was significant during the early Space Race when the United States and the Soviet Union competed to explore space.

The Significance of the Mission

John Glenn’s mission was not just a milestone in the Cold War rivalry between the United States and the Soviet Union but a global event. In 1961, the Soviet Union launched cosmonaut Yuri Gagarin into orbit, marking the first human spaceflight. The United States, eager to match this achievement, sent John Glenn into orbit the following year. His successful space flight proved NASA’s space exploration skills and demonstrated the United States’ ability to compete in the global space exploration race.

The Flight of Friendship 7

At 9:47 a.m. EST, Glenn launched aboard the Atlas LV-3B rocket from Cape Canaveral, Florida. His spacecraft, Friendship 7, soared through space at velocities exceeding 17,500 miles per hour, completing three orbits in under five hours. During the mission, Glenn provided valuable observations about spaceflight, such as how weightlessness affected the human body, which was crucial for future astronaut training, and how the Earth’s surface appeared from orbit, which provided a unique perspective on our planet.

The spacecraft encountered multiple difficulties during its operation, adding a layer of drama to Glenn’s mission. A faulty sensor incorrectly indicated that the spacecraft’s heat shield was loose, which could have resulted in disaster upon reentry to Earth. Despite the uncertainty, Glenn’s heroism shone through as he successfully navigated the return to Earth’s atmosphere safely before landing in the Atlantic Ocean, where the USS Noa rescued him.

A Hero’s Welcome

When John Glenn returned from space, America held massive nationwide celebrations in his honor. In New York City, there was a grand ticker-tape parade where President John F. Kennedy awarded him the NASA Distinguished Service Medal. Glenn’s mission made him an American hero and paved the way for future space missions, including the Apollo moon landing, which ultimately became a reality.
