Since 1957, when the Soviet Space Agency launched a satellite, human beings began to explore the universe.
This action is still going on now: humans landed on the moon, unmanned aerial vehicles entered deep space, explored Mars, recorded signals outside the solar system, and reached different corners of the universe again and again.
The following are three milestones in the history of human space exploration:
1. Apollo 1 1, man landed on the moon for the first time. 1969 On July 20th, NASA became the first space agency to send a man to the moon. On that day, neil armstrong became the first man to land on the moon, followed by another astronaut, buzz aldrin. Apollo 1 1 is a manned moon landing spacecraft, piloted by Michael collins.
Just after landing on the surface of the moon, astronaut Armstrong said the first sentence of the article, which indicates that human beings have mastered the ability to land on other planets.
They collected samples from the surface of the moon and took photos. They hung an American flag on the surface of the moon before returning to the spaceship. 1On July 24th, 969, they returned to Earth safely and successfully completed the feat of landing on the moon.
2. yuri gagarin, the first man to go into space 196 12 On April 2 12, yuri gagarin created the first record of human going into space.
He was sent into space by the Dongfang-1 spacecraft built by the Soviet Space Agency. It also became the first manned spacecraft in the history of space exploration. The mission duration of Dongfang No.1 is 1 hour and 48 minutes.
Apollo 8, the first spaceship to fly around the moon, and apollo 8, the first manned spaceship to fly around the moon. The manned spacecraft was launched in 1968. Frank Baumann, James Lovel and William Anders were the crew members of the apollo 8 mission.
It successfully flew in the orbit of the moon and returned to earth safely. Apollo 8's crew became the first person to observe the whole earth in extraterrestrial orbit.
Their photo of "The Earth Rising from the Moon Orbit" has also become one of the most unforgettable photos in human history.
The earth rises from the orbit of the moon.
It is with these wave after wave pioneers that human beings can continue to explore and develop, and we can stand higher and see farther.
Finally, I want to end with Kennedy's speech before the start of the moon landing program:
We decided to go to the moon.
We decided to go to the moon and realize more dreams in this decade, not because they are easy, but because they are full of difficulties. Because this goal will make us achieve the best organization and test our top technology and strength, because we are willing to accept this challenge, because we are unwilling to postpone this challenge, because we are determined to win this challenge, and so are other challenges.
Pay tribute to all astronauts.
