Sixty-three years ago today, on February 20, 1962 (January 16, 1962 in the lunar calendar), John Green became the first American astronaut to orbit the earth. Green and his wife Anne in Houston John Green was once the realizer of the glory and dream of an entire generation of Americans. At 9:47 a.m. on February 20, 1962, Green took off on the American manned spacecraft "Friendship" 7, orbiting the earth three times. He was the first American astronaut to orbit the earth. At 2 pm on October 29th, 1998, the American space shuttle Discovery took off from Kennedy Space Center in Florida and traveled in space for nine days. In his twilight years, he went out to war and won honor not only for the United States, but also for the whole mankind in the struggle to conquer nature. Green was born on July 18th, 1921 in Cambridge, Ohio, USA. After graduating from high school, he was admitted to Muskingham University. After the attack on Pearl Harbor broke out, he joined the newly formed Naval Air Training Team. In 1943, he joined the U.S. Marine Corps and participated in the South Pacific Campaign. Green served as a test pilot in the Marine Corps for several years, primarily flying jet fighters. In 1957, he flew from Los Angeles to New York at an average speed, setting the speed record for a cross-land flight. Since 1959, Green has participated in three years of training as one of the first astronauts in the American space program. This was an event that made him very excited. He once wrote, "When I was a child, I used to look up at the stars and look at the shining stars and think: What's up there? How do we get there? Now I can finally realize my dream." On February 20, 1962, he became the first American to orbit the earth. Although this flight had a certain cold war color (the United States and the Soviet Union were in a space contest at that time), it was still a major victory for mankind to conquer space. Green retired in 1965, ending his successful military career. Since then, he has gone into business and politics. Won the Senate seat in 1974. Since then, he has been recorded in American history as a four-term Ohio Senator in *. Green is stubborn and persistent in doing things. He insists on the annual routine physical examination, firmly believing that he will return to space one day. I finally got my wish in 1998; At the same time, his behavior is of great benefit to studying the effects of space flight and gravity-free state on human aging. In 1998, he underwent a physical exam before liftoff. In 1998, he was trained in escape methods. In 1998, he helped Chiaki Mukai, a Japanese doctor of physiology who took off with him, wear a spacesuit. In 1962, Green landed by helicopter in the first astronauts of the U.S. space program (third from left) in the laboratory with his son and two grandchildren
