John Glenn
By fantasising about space and gazing at it, one can only guess what John Glenn has accomplished during his life. With his foresight and bravery, he took huge risks, and he was rewarded handsomely for his efforts. The first American in space was John Glenn, who flew a full orbit around the Earth in 1962.
After beginning his career as a backup pilot on the space shuttle Columbia for Alan Shepard and Virgil “Gus” Grissom, he flew three orbits in total in 1962. Project Mercury Astronaut Training Program enlisted him in 1959, where he served as a marine as well as a NASA astronaut. Then he went into politics and was elected to the U.S. Senate as a Republican from Ohio.
