1On July 20th, 969, the Apollo module landed on the surface of the moon and started the activities of landing on the moon in human history. By 1972, man had landed on the moon six times and made a series of scientific investigations on the moon, which made his understanding of the moon more comprehensive and in-depth.

The result of the race to the moon
In the late 1950s and early 1960s, the former Soviet Union won several space races in succession: 1957, 65438+/kloc-0 launched its first artificial earth satellite on October 4th, 196 1 April 2nd, the first astronaut Gagarin went into space ...
But it pales in comparison with the great achievements of the Soviet Union. Less than four weeks after Gagarin's flight, American astronaut Lieutenant Colonel alan shepard made a suborbital flight (186 km) in the Mercury spacecraft, which showed that the United States had the ability to get rid of the space dilemma.
Man's achievements in landing on the moon
Soviet Luna 2 landed on the moon in September 1959, which was the first probe to land on the moon, while American Apollo 1 1 successfully landed on the moon in July 1969, and astronauts neil armstrong and buzz aldrin became the first human beings to land on the moon in history.
1865 From the Earth to the Moon, a novel by French novelist jules verne, is one of the earliest concepts about landing on the moon. China's lunar exploration project refers to the lunar exploration program officially launched by China National Space Administration in March 2003.
Overview of Apollo program
Apollo program, or Apollo program, is a series of manned space missions from 196 1 to 1972. In the decade of 1960s, we mainly devoted ourselves to the goal of manned landing on the moon and safe return. 1969, Apollo 1 1 spacecraft achieved this goal, and neil armstrong became the first man to set foot on the surface of the moon.
For further scientific exploration on the moon, the Apollo program lasted until the early 1970s, with a total cost of about $24 billion, so some people think that money is the biggest factor for the United States to walk in front of the moon.
Apollo program is NASA's largest lunar exploration program to date. The mission of Apollo spacecraft, including preparing for manned landing on the moon and realizing manned landing on the moon, ended at 1972. So far (20 12), no other manned spacecraft has left Earth orbit.
The Apollo program revealed the surface characteristics, chemical composition and optical characteristics of the moon in detail, and detected the gravity, magnetic field and earthquake of the moon. Later, the Skylab program and the Apollo-Alliance test program jointly organized by the United States and the Soviet Union also used the equipment originally built for Apollo, which is usually considered as part of the Apollo program.
The Apollo program was a great success, but there were several serious crises in the program, including the fire that killed Virgil Grissom, edward white and roger chaffee during the Apollo/KLOC-0 test. The explosion of the oxygen tank of Apollo 13 and the toxic gas released when the Apollo-Soyuz test plan returned to the atmosphere almost killed the astronauts on the mission.
