Former Soviet cosmonaut Yuri Gagarin was the first person to enter space. On April 12, 1961, he took the Vostok 1 spacecraft and flew around the earth for 108 minutes before returning safely to the ground.

Just three weeks after Gagarin successfully entered space, American astronaut Alan Shepard flew in the Earth's suborbital orbit on the Mercury 3 spacecraft for 15 minutes.

In February 1962, American astronaut John Glenn entered Earth orbit for the first time and took the first photos of the Earth from space through the porthole of the Mercury 6 spacecraft.

In June 1963, former Soviet astronaut Valentina Tereshkova flew into space in the Vostok 6 spacecraft, becoming the first woman in space;

In March 1965, former Soviet astronaut Alexey Leonov conducted the first human spacewalk for 12 minutes aboard the Voskhod spacecraft. Due to the expansion of his spacesuit, he almost failed to climb back into the cabin.

On July 20, 1969, the Apollo 11 spacecraft successfully landed on the Earth’s satellite, the moon. American astronaut Neil Armstrong was the first to set foot on the desolate and silent land of the moon, and said a famous saying that has been often quoted on countless occasions since then: "This is a small step for a man, but a step for mankind." A big step.
