What are the installations of the Apollo spacecraft?

The total weight of the spacecraft is 45 tons, and the height is about 16 meters, which is about 25 meters including the life-saving tower, in which the command cabin is conical, high, with a diameter at the bottom, weighing about 6t; The service compartment is a cylindrical body with a high diameter and weighs about 25 t; And the lunar module is high, wide and has a mass of 14t.

It is composed of three parts: the command module, the service module and the lunar module. The command module is conical in shape and is the main body of the spacecraft, where the astronauts live and work. The cabin is equipped with various control and control instruments, astronauts' equipment, food, water and waste disposal equipment, etc.

The service module is cylindrical, and immediately below the command module is the engine room and warehouse of the spacecraft, where the main rocket, fuel, power supply, oxygen, water and other high-quality products are all here. The spacecraft's entry into lunar orbit, its orbit change when it orbits the moon, and its exit from the lunar orbit when returning to Earth are all achieved by the thrust of the main rocket.

The success of the Apollo moon landing is undoubtedly of great scientific and technological significance, because it is the first time that human beings have left the earth to reach other celestial bodies, and it is a new milestone in human penetration into space, and it is a leap. As human beings continue to penetrate into space and explore the mysteries of the universe, the moon will also become a bridgehead.

The success of the moon landing has also created conditions for mankind to open up new powerful domains and develop and utilize the moon. Scientists say much of what they know about the moon and the entire solar system was confirmed and revealed by the Apollo 11 astronauts, and that the study of the moon rocks and dust brought back also played a big role.

The moon has become more and more important for the development of human space science and technology, and the Apollo moon landing, in addition to expeditions, will also establish a nuclear power science station on the moon; driving a lunar rover for activities; A total of 400 kilograms of lunar rock and soil samples were collected, which were brought back to Earth for further scientific analysis.

The Apollo spacecraft consists of three parts: the command module, the service module and the lunar module, and there is an escape tower above the command module during launch. The total weight of the spacecraft is about 50 tons, and the height is about 16 meters, and the lifeguard tower is about 25 meters. , in which the command cabin is conical, high, with a diameter at the bottom, weighing about 6t; The service compartment is a cylindrical body with a high diameter and weighs about 25 t; And the lunar module is high, wide and has a mass of 14t.

The Apollo spacecraft was next to the United States.

The Apollo spacecraft was used by the United States in the process of carrying out a manned landing on the moon. On July 20, 1969, the Apollo 11 spacecraft made its first attempt to land on the moon. Since then, the United States has launched the "Apollo" spacecraft six times one after another, five of which have been successful, and a total of 12 astronauts have landed on the moon to dismantle and sell the ball.

The Apollo spacecraft is the third generation of American manned spacecraft in the family. Between 1966 and 1972, a total of 17 ships were launched: 1 3 was a simulated spacecraft, 4 6 was an unmanned spacecraft, 7 10 was a manned spacecraft orbiting the Earth or the Moon, and 11 17 was a manned lunar spacecraft.

After the argumentation of rocket experts such as NASA and von Braun, it was proposed that the goal that the United States was able to achieve through efforts in the 60s of the 20 th century, but which just surpassed the former Soviet Union, was a manned landing on the moon. As a result, the United States ** Kennedy announced the "Apollo" manned moon landing program on May 25, 1961.

The Apollo spacecraft consisted of a command module, a service module, and a lunar module. On July 16, 1969, the United States used the "Saturn" 5 carrier rocket to send the "Apollo" 11 spacecraft with three astronauts on board, and the spacecraft arrived on the moon on July 21, and the American astronaut Armstrong realized the dream of human landing on the moon.

In order to carry out the "Apollo" program, the United States also developed the "Prowler," "Surveyor," and "Lunar Orbiter" unmanned lunar probes, the Saturn Heavy carrier rocket, and the Apollo spacecraft, which consisted of an escape system, a command module, a service module, and a lunar module, and laid a solid technical foundation for sending people to the moon in 1969.

The Apollo moon landing program began on May 23, 1961, and ended in December 1972. During this period, a total of 17 flight tests were carried out, of which "Apollo" 1 to "Apollo" 6 were unmanned suborbital and Earth orbital flights; "Apollo" 7 is a manned Earth vertical draft orbital flight; Apollo 8 and 9 were manned lunar orbital flights, and Apollo 11 to Apollo 17 were manned lunar flights (only Apollo 13 failed). The Apollo program spent a total of $24 billion to complete six lunar flights, sending 12 people to the moon and returning them safely to the ground.

It not only achieved the political goal of the United States to catch up with and surpass the former Soviet Union, but also promoted the development of American science and technology, especially propulsion, guidance, structural materials, electronics, and management science. However, the "Apollo" program was too expensive, accounting for almost 3 5 of the entire funding of the space agency in the 60s of the 20th century, seriously affecting the development of space science and space applications in the United States, and forcing the United States to reconsider the next space goal.

The spacecraft used by the United States in the process of carrying out a manned landing on the moon. The Apollo 11 spacecraft first realized the ideal of landing on the moon on July 20-21, 1969. The spacecraft consists of three parts: a command module, a service module and a lunar module.

Among them, the command module is the control center of the whole spacecraft, and it is also the cockpit of the astronauts who live and work in flight. The service module adopts a light metal honeycomb structure, and is divided into 6 compartments around it, which houses the main engine, propellant tank, pressurization, attitude control, electrical and other systems. The front end of the service cabin is docked with the command module, and the rear end has a nozzle for the main engine of the propulsion system.

The lunar module consists of a descent stage and an up-upgrade stage. Spaceship.
