John Glenn, whose 1962 flight as the first U.S. astronaut to orbit the Earth made him an all-American hero and propelled him to a long career in the U.S. Senate, died Thursday. The last survivor of the original Mercury 7 astronauts was 95.

Glenn died at the James Cancer Hospital in Columbus, where he was hospitalized for more than a week, said Hank Wilson, communications director for the John Glenn School of Public Affairs.

John Herschel Glenn Jr. had two major career paths that often intersected: flying and politics, and he soared in both of them.

Before he gained fame orbiting the world, he was a fighter pilot in two wars, and as a test pilot, he set a transcontinental speed record. He later served 24 years in the Senate from Ohio. A rare setback was a failed 1984 run for the Democratic presidential nomination.

His long political career enabled him to return to space in the shuttle Discovery at age 77 in 1998, a cosmic victory lap that he relished and turned into a teachable moment about growing old. He holds the record for the oldest person in space.

More than anything, John Glenn was the ultimate and uniquely American space hero: a combat veteran with an easy smile, a strong marriage of 70 years and nerves of steel. Schools, a space center and the Columbus, Ohio, airport were named after him. So were children.

The Soviet Union leaped ahead in space exploration by putting the Sputnik 1 satellite in orbit in 1957, and then launched the first man in space, cosmonaut Yuri Gagarin, in a 108-minute orbital flight on April 12, 1961. After a two suborbital flights by Alan Shepard Jr. and Gus Grissom, it was up to Glenn to be the first American to orbit the Earth.

“Godspeed, John Glenn,” fellow astronaut Scott Carpenter radioed just before Glenn thundered off a Cape Canaveral launch pad, now a National Historic Landmark, to a place America had never been. At the time of that Feb. 20, 1962, flight, Glenn was 40 years old.

With the all-business phrase, “Roger, the clock is operating, we’re underway,” Glenn radioed to Earth as he started his 4 hours, 55 minutes and 23 seconds in space. Years later, he explained he said that because he didn’t feel like he had lifted off and it was the only way he knew he had launched.

During the flight, Glenn uttered a phrase that he would repeat frequently throughout life: “Zero G, and I feel fine.”

“It still seems so vivid to me,” Glenn said in a 2012 interview with The Associated Press on the 50th anniversary of the flight. “I still can sort of pseudo feel some of those same sensations I had back in those days during launch and all.”

Glenn said he was often asked if he was afraid, and he replied, “If you are talking about fear that overcomes what you are supposed to do, no. You’ve trained very hard for those flights.”

Glenn’s ride in the cramped Friendship 7 capsule had its scary moments, however. Sensors showed his heat shield was loose after three orbits, and Mission Control worried he might burn up during re-entry when temperatures reached 3,000 degrees. But the heat shield held.

Even before then, Glenn flew in dangerous skies. He was a fighter pilot in World War II and Korea who flew low, got his plane riddled with bullets, flew with baseball great Ted Williams and earned macho nicknames during 149 combat missions. And as a test pilot he broke aviation records.

The green-eyed, telegenic Marine even won $25,000 on the game show “Name That Tune” with a 10-year-old partner. And that was before April 6, 1959, when his life changed by being selected as one of the Mercury 7 astronauts and instantly started attracting more than his share of the spotlight.

Glenn in later years regaled crowds with stories of NASA’s testing of would-be astronauts, from psychological tests — come with 20 answers to the open ended question “I am” — to surviving spinning that pushed 16 times normal gravity against his body, popping blood vessels.

But it wasn’t nearly as bad as coming to Cape Canaveral to see the first unmanned rocket test.

“We’re watching this thing go up and up and up … and all at once it blew up right over us, and that was our introduction to the Atlas,” Glenn said in 2011. “We looked at each other and wanted to have a meeting with the engineers in the morning.”

In 1959, Glenn wrote in Life magazine: “Space travel is at the frontier of my profession. It is going to be accomplished, and I want to be in on it. There is also an element of simple duty involved. I am convinced that I have something to give this project.”

That sense of duty was instilled at an early age. Glenn was born July 18, 1921, in Cambridge, Ohio, and grew up in New Concord, Ohio, with the nickname “Bud.” He joined the town band as a trumpeter at age 10 and accompanied his father one Memorial Day in an echoing version of “Taps.” In his 1999 memoir, Glenn wrote “that feeling sums up my childhood. It formed my beliefs and my sense of responsibility. Everything that came after that just came naturally.”

His love of flight was lifelong; John Glenn Sr. spoke of the many summer evenings he arrived home to find his son running around the yard with outstretched arms, pretending he was piloting a plane. Last June, at a ceremony renaming the Columbus airport for him, Glenn recalled imploring his parents to take him to that airport to look at planes whenever they passed through the city: “It was something I was fascinated with.” He piloted his own private plane until age 90.

Glenn’s goal of becoming a commercial pilot was changed by World War II. He left Muskingum College to join the Naval Air Corps and soon after, the Marines.

He became a successful fighter pilot who ran 59 hazardous missions, often as a volunteer or as the requested backup of assigned pilots. A war later, in Korea, he earned the nickname “MiG-Mad Marine” (or “Old Magnet A — ,” which he sometimes paraphrased as “Old Magnet Tail.”)

“I was the one who went in low and got them,” Glenn said, explaining that he often landed with huge holes in the side of his aircraft because he didn’t like to shoot from high altitudes.

Glenn’s public life began when he broke the transcontinental airspeed record, bursting from Los Angeles to New York City in 3 hours, 23 minutes and 8 seconds. With his Crusader averaging 725 mph, the 1957 flight proved the jet could endure stress when pushed to maximum speeds over long distances.

In New York, he got a hero’s welcome — his first tickertape parade. He got another after his flight on Friendship 7.

That mission also introduced Glenn to politics. He addressed a joint session of Congress, and dined at the White House. He became friends with President Kennedy and ally and friend of his brother, Robert. The Kennedys urged him to enter politics, and after a difficult few starts he did.

Glenn spent 24 years in the U.S. Senate, representing Ohio longer than any other senator in the state’s history. He announced his impending retirement in 1997, 35 years to the day after he became the first American in orbit, saying “there is still no cure for the common birthday.”

Glenn’s returned to space in a long-awaited second flight in 1998 aboard the space shuttle Discovery. He got to move around aboard the shuttle for far longer — nine days compared with just under five hours in 1962 — as well as sleep and experiment with bubbles in weightlessness.

In a news conference from space, Glenn said “to look out at this kind of creation out here and not believe in God is to me impossible.”

NASA tailored a series of geriatric-reaction experiments to create a scientific purpose for Glenn’s mission, but there was more to it than that: a revival of the excitement of the earliest days of the space race, a public relations bonanza and the gift of a lifetime.
