The Mercury and Vostok programs were significant milestones in the Space Race between the United States and the Soviet Union. During this period, both nations aimed to send humans into space for the first time.

Mercury Program The United States' Mercury program, launched in 1958, was the nation's first human spaceflight program. It aimed to put American astronauts into Earth orbit and gather valuable data about human space travel.

One of the most iconic moments of the Mercury program was the flight of Alan Shepard aboard the Freedom 7 spacecraft on May 5, 1961. Shepard became the first American to travel to space, although his flight only lasted about 15 minutes. Nevertheless, this successful mission boosted morale in the United States and demonstrated their capabilities in space exploration.

Vostok Program Meanwhile, the Soviet Union's Vostok program was successfully launched in 1961 with the goal of sending the first human, Yuri Gagarin, into space. On April 12, 1961, Gagarin became the first person to orbit the Earth in the Vostok 1 spacecraft. His mission lasted for about 108 minutes, during which he completed one orbit around the planet. Gagarin's achievement not only made him a national hero in the Soviet Union but also marked a significant milestone in human space exploration.
