The achievement came 10 months after Soviet Cosmonaut Yuri Gagarin became the first human in space and made one full orbit around Earth (April 12, 1961) and nine months after Alan Shepard became the first American in space (May 5, 1961), followed by Gus Grissom (July 21, 1961). Thus, his mission was a critical step in the American mission to win the Cold War in space by fulfilling President John F. Kennedy, Jr.’s commitment to “achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth.”
TIME launched its profile of Glenn by pointing out that the grandeur of the undertaking was quite matched by the affect of the man: “In his flight across the heavens, John Glenn was a latter-day Apollo, flashing through the unknown, sending his cool observations and random comments to the earth in radio thunderbolts, acting as though orbiting the earth were his everyday occupation. Back on earth, Glenn seemed to be quite a different fellow—an enormously appealing man, to be sure, but as normal as blueberry pie.”
The Ohio native’s life had indeed started out in complete normalcy: he spent his time playing football and basketball, and reading Buck Rogers. He later joined the Marine Corps, becoming a decorated test pilot and a combat flyer, earning the rank of colonel. (Ted Williams, the legendary Red Sox left fielder who was also a Marine pilot, told TIME, “The man is crazy,” referring to the way he apparently liked to show off his flying skill in dangerous stunts.) But, though his achievements as a pilot were notable, as a career it was still within the range of ordinary.
So how did he get to be an astronaut? TIME explained:
In terms of what it felt like to be in space, he reported “no ill effects at all” from zero gravity and described weightlessness as “something you could get addicted to.” It was also “hot” inside the Friendship 7 capsule at times; at one point, the temperature hit 108º in the cabin. He saw four “beautiful” sunsets and said nightfall in space is akin to nightfall in the desert “on a very clear, brilliant night when there’s no moon and the stars just seem to jump out at you.”

While TIME declared, “Not since Lindy had the U.S. had such a hero”—referring to Charles Lindbergh, who accomplished the first solo nonstop flight across the Atlantic Ocean—Glenn tried to emphasize at a press conference following his splashdown in the Atlantic Ocean that spaceflight still had a long way to go: “If you think of the enormity of space, it makes our efforts seem puny. But these are all step-by-step functions we go through. The manned flights we’ve had to date have added information. This flight, I hope, added a bit more. And there are more to come.”
