The First American in Orbit: The 10 Seconds That Shook John Glenn -- 64th Anniversary of His Orbital Flight

Countdown, Then Silence

"5, 4, 3, 2, 1... ignition."

At 9:47 AM on February 20, 1962, an Atlas rocket tore through the sky above Cape Canaveral, Florida. Sitting alone inside the capsule, 40-year-old Marine pilot John Glenn radioed in a tense voice: "Roger, clock." That brief moment was etched into American history forever.

Today, on the 64th anniversary of that flight, we look back at one man's courageous challenge, born under the blade of the Cold War.

America's Wounded Pride, Trailing the Soviet Union

When the Soviet Union launched Sputnik in 1957, America was shocked. In 1961, Yuri Gagarin completed the first human orbital flight, once again proving Soviet superiority. Alan Shepard became the first American in space, but his was a simple suborbital flight, not an orbit. American pride hit rock bottom, and NASA was desperate.

The Mercury program's last card was John Glenn. He was a Korean War veteran and an exceptional test pilot. Above all, he was a perfectionist. Legend has it that before launch, Glenn personally inspected every bolt on the capsule.

"Friendship 7" Circles the Earth Three Times

The capsule Glenn rode that day was named Friendship 7 -- a name Glenn chose himself. Over 4 hours and 55 minutes, it circled the Earth three times at a top speed of 28,000 km/h. Yet from start to finish, the flight was a series of harrowing moments.

Mid-flight, the automatic attitude control system malfunctioned. Glenn calmly switched to manual control of the capsule. The bigger crisis came just before re-entry. Instruments at ground control picked up a signal indicating that the heat shield may have come loose. If true, the capsule would become a fireball during atmospheric re-entry, and Glenn would be incinerated.

Ground control chose not to tell Glenn the truth, instead instructing him not to jettison the retro-rocket package during re-entry. Glenn was puzzled but followed orders. Fortunately, the heat shield was fine, and the capsule splashed down safely in the Atlantic. Glenn later recalled: "Those 10 seconds felt like the longest of my life."

The Legacy of a Cold War Hero

Glenn's return sent America into a frenzy. In Manhattan alone, 4 million people turned out for the ticker-tape parade, and President Kennedy personally welcomed him. Beyond a simple space flight, this success signaled to the world that America had gained a foothold to strike back in the space race against the Soviet Union.

Even more remarkable is what came after. In 1998, at the age of 77, Glenn returned to space aboard the Space Shuttle Discovery, setting the record as the oldest astronaut. He passed away in December 2016, at the age of 95.

This History on Screen

John Glenn's story has been brought to life on screen multiple times.

The Right Stuff (1983) is a classic film about the Mercury astronauts. Ed Harris portrayed John Glenn, vividly capturing the tension on the eve of launch and the competitive spirit among the men. However, the film has been noted for somewhat exaggerating conflicts between the astronauts for dramatic effect. In 2020, Disney+ remade it as a drama series of the same name, taking a longer, deeper look at the era.

Hidden Figures (2016) tells the story of the Black women mathematicians who supported Glenn's flight from behind the scenes. In reality, Glenn trusted Katherine Johnson's hand calculations more than the computer. Glenn's famous line in the film is based on a true story.

Space Still Calls Us

Sixty-four years later, humanity looks once again toward the Moon and dreams of Mars. But at every starting point, there was that moment when one man quietly steadied his breathing inside a tiny capsule. There was that voice that swallowed fear and answered, "Roger."

History has always been made by people like that.
