Verified · NASA

On April 12, 1961, Soviet cosmonaut Yuri Gagarin lifted off from the Baikonur Cosmodrome aboard Vostok 1, becoming the first human to leave Earth. In a single orbit lasting just 108 minutes, his capsule looped the planet at roughly 27,400 km/h, reaching an altitude of more than 300 kilometers before plunging back through the atmosphere.

The flight was almost entirely automated; planners feared weightlessness might incapacitate a pilot. Gagarin did not land inside his spacecraft—he ejected at about 7 kilometers and parachuted down separately, a detail the Soviets kept quiet for years.

“I see Earth. It is so beautiful,” he reportedly radioed from orbit.

Gagarin’s flight stunned the United States and intensified the Space Race, helping push President Kennedy to commit to a crewed Moon landing. The 27-year-old returned an instant icon, celebrated across the Soviet bloc and honored as a Hero of the Soviet Union.
