From ancient times to the present, many people have looked up at the distant sky with admiration and watched the stars in the starry sky.
We are full of awe and curiosity about the universe, and we look forward to the day when human beings can conquer the universe and open up a new home for mankind.
Although this dream is still a distant dream for us now, with the advancement of science and technology, many scientists are constantly working towards this goal.
Not to be outdone, the Chinese have been promoting the mainland's space exploration.
Not long ago, a medical device company called "Wanhu" in Yingkou, Liaoning Province, on the mainland, actually developed a rocket that could be lifted into space.
This has undoubtedly brought infinite hope to the mainland's space exploration cause, aroused heated discussions among many people, and even attracted international attention.
And before that, who has the mainland's space exploration cause related to, and what are the major events?
1. Wanhu created the first lift-off rocket.
In 2019, a medical device company called "Wanhu" in Yingkou, Liaoning Province, developed a rocket that could be lifted into space.
The rocket has a unique shape, and the exterior is made by CNC cutting technology, and the surface is very smooth, and the experiment was very successful, and then the "Wanhu" company also launched a rocket model that can carry human rides.
This liftoff rocket not only has a beautiful appearance, but also has the power to carry humans into space.
At the head of the rocket, there is also a camera, which can capture the footage of the rocket in real time, and the captured footage can be transmitted to the computer on the ground in real time.
This rocket can be used not only as a recreational item, but also as an educational item to popularize space knowledge.
Let's take a look at the history of space exploration on the continent.
On February 19, 1958, the first artificial earth satellite independently designed and manufactured by the mainland was successfully launched, and Zhou Enlai, the central leader, personally announced the successful launch of the artificial satellite.
This news shocked the whole world and marked that the mainland has become the third country with satellite launch capabilities after the Soviet Union and the United States.
Prior to this, on October 4, 1957, the Soviet Union successfully launched the world's first artificial earth satellite, "Vostok 1", which was named "Sputnik 1".
Through this move, the Soviet Union completely got rid of the title of "backward power" and became the only aviation power at that time.
The Soviet Union not only wanted to show its "arrogance," but also wanted to prove its strength in science and technology and win international reputation by launching satellites, so as to strive for more benefits for its economic development and national security.
Therefore, the Soviet Union became the hegemon of the world with its strong strength at that time, and it led the trend of international scientific and technological development.
The United States was greatly shaken by the Soviet Union's successful launch of an artificial satellite, and the United States was still in fierce competition with the Soviet Union in space exploration, so the United States did not want its reputation to be overshadowed by the Soviet Union.
In 1958, with the efforts of the United States, the United States finally successfully launched its own artificial satellite "Explorer 1", which also won a response in the international community.
II. The Soviet Union and the American Space Race.
The rivalry between the Soviet Union and the United States over space exploration, also known as the "space race," was part of a burgeoning ideological conflict between the Soviet Union and the United States, as well as a Cold War-era rivalry between the two.
In the three years since the Soviet Union successfully launched artificial satellites, the Soviet Union has successfully launched many artificial satellites, including "World One", "Luna One", and "Mars One".
The United States did not want to see the Soviet Union's international reputation growing, so the United States, under the pressure of the Soviet Union, was also rapidly promoting the development of the space exploration program in the United States at that time.
It has also successfully launched a number of artificial satellites, but when it comes to space exploration, the United States is still in a relatively weak position compared to the Soviet Union.
The Soviet Union not only launched artificial satellites, but also took pictures of the moon through the "Luyue-1" probe, and also detected information such as the terrain and environment on the far side of the moon.
Through these initiatives, the Soviet Union put itself in a powerful position in the international arena and won international response and applause.
The United States, on the other hand, adopted a more cautious attitude, and only after the successful launch of the "Shenzhou" space capsule built by the mainland did the United States begin to invest more vigorously in space exploration.
In 1969, the Apollo program of the United States was a success, and the United States successfully brought two astronauts "Armstrong" and "Aldrin" and "Armstrong" to the surface of the moon in the "Apollo 11" mission, becoming the first astronaut to land on the moon in human history.
Since then, the United States has completely surpassed the Soviet Union and become the first country in human history to "leave footprints" on the moon.
The success of the Apollo program made the United States happy for a while, and it also won the United States an international "reputation." The United States also took advantage of the victory to pursue, not only successfully carrying out many manned lunar landing programs, but also building a permanent lunar base on the moon for studying the moon's crustal structure and resources.
3. Apollo 13 mission.
On April 11, 1970, the United States successfully launched the Apollo 13 spacecraft, this time the Apollo 13 mission was to continue the traces of "Apollo 12", "Apollo 12" and "Apollo 12" left by Apollo 12 on the lunar surface, and bring Americans to the lunar surface.
Let them be able to conduct some scientific experiments on the moon, study the environment and topography of the moon, and bring the collected samples of lunar soil and stones back to the earth for analysis, so as to promote more human understanding of the moon and make more improvements for human life.
The Apollo 13 mission was aborted and the astronauts were forced to return to Earth after a liquid oxygen tank exploded, depriving the entire spacecraft of the energy needed to continue the lunar landing.
During this mission, astronauts "Jade", "Lovell" and "Fred" were about to begin inspecting the spacecraft for several hours the day before returning to Earth from the moon to ensure that the spacecraft could return safely to Earth, but some problems arose with this inspection.
Since the spacecraft needs to maintain electricity and maintain temperature in space, it is necessary to burn liquid oxygen for adjustment when performing these operations, but the battery inside the spacecraft is insufficient to burn liquid oxygen.
Since liquid oxygen cannot be burned, the temperature inside the spacecraft cannot be maintained, so the temperature inside the spacecraft will continue to drop, which will eventually lead to the freezing and cracking of the parts and instruments inside the spacecraft, and it will not be able to continue to operate normally.
In order to solve this problem, engineers on the ground decided to wake up the astronauts to burn liquid oxygen and adjust the temperature, but before these operations can be carried out, the spacecraft's circuit must be cut off to prevent the circuit from short-circuiting and causing the spacecraft to explode.
With the joint efforts of astronauts and ground engineers, they finally succeeded in solving the problem of the spacecraft, preventing the explosion of the spacecraft, and finally, the three astronauts successfully returned to Earth and completed the mission.
IV. Conclusion
Human exploration of the universe is still in its infancy, and there are still many things we do not know about space exploration.
In this context, the process of space exploration is full of many uncertainties, therefore, the risks in space exploration are also very large, and every space mission needs to undergo rigorous testing and inspection to ensure the integrity of the equipment and the safety of astronauts.
The successful return of the Apollo 13 mission not only fully demonstrated the professionalism of the astronauts and the importance of teamwork, but also demonstrated the great spirit of the mainland's aerospace personnel, which is worthy of all of us to learn from and promote.
