Today, chang'e-5 has successfully obtained 2 kg of lunar soil and is on the way back. However, with the prosperous development of China's space instry, Japan's space instry has also ushered in heavy news. Japan's falcon-2 probe launched in 2014 will also return from space

as two powerful countries in Asia, this is the embodiment of advanced aerospace technology. What is the difference in the difficulty of extraterrestrial sampling between China and Japan? Who is more powerful than chang'e-5 and Japanese falcon-2

these two lunar sampling projects took place in the early 1970s, and no other country has carried out lunar sampling in the next 50 years. The significance of the lunar sampling of chang'e-5 is different, becoming the third country to carry out lunar sampling after the United States and the Soviet Union

the success of this mission will not only improve China's aerospace technology level, but also be of great significance for China's future lunar exploration project

In general, the technology of chang'e-5 is more difficult and the operation is more complicated. This mission will be the most complicated one in China so far

After the Long March 5 completed its mission of more than ten days, our chang'e-5 finally landed on the land and completed its own exploration mission of more than ten days. For this matter, netizens can be said to have a lot of discussion, and on the landing on the moon, I also have my own views, to share with you{ RRRRR}

what is the significance of lunar landing

for most ordinary people, they can't understand what value we can create by landing on the moon. In fact, for most people, landing on the moon is not a successful turning point, but in the whole process of landing on the moon, our space technology continues to develop, and we collect important experimental data through some missions, It will lay the necessary foundation for the future exploration of the universe

The Apollo program, which successfully landed on the moon six times, brought back 382kg of lunar rocks and made a lot of scientific achievements in understanding the nature and origin of the moon! Now the Chinese lunar sampling probe is about to start. The melon eaters are very concerned about where it will land, how to sample, how many rocks it will bring back, and how to return to the earth

New Moon Alliance: what's the use of NASA's international agreements in the United States, Australia, Canada, Italy, Japan, Luxembourg, the United Arab Emirates and the United Kingdom? The future is China's manned landing on the moon and so on. Don't blame us Chinese for not reserving a seat for you

International influence and shock are very high, especially touched the sensitive nerves of the United States and other western countries! The specific impact will be a long-term and wonderful competition process among the big powers in the future, which depends on their comprehensive strength in economy, science and technology. China's space program is steadily advancing... Our grand goal is to put the stars in the sea, instead of learning to fly first and then go to heaven, as Japan and India do

Some people say that we are still behind, which is good. We're the third person to go back and forth between the moon and the earth. We never deny that there is a gap. We haven't developed a giant rocket like Saturn V, but we should see that we have a good foundation and created many firsts, such as landing on the moon. We should also see hope. For example, Zhou Chengyu, known as the elder sister, is a young group of new astronauts who have been handed down from generation to generation and are full of vigor and vitality. With the development and progress of China's national strength, China's space instry should have a bright future. Obviously, many countries have taken the initiative to seek cooperation with us

some people worry about chips and engines. Facts have proved that everything is made in China and reliable. Take the 107 engine as an example, without mistakes and problems, it can be achieved by taking down the earth from the moon

On December 17, the chang'e-5 spacecraft returned to earth with lunar samples. The third step of the third phase of the lunar exploration project was a complete success, which is not only of great significance, but also of far-reaching influence

In the 21st century, Russia has also started the research of manned lunar landing, and plans to develop super heavy carrier rocket, new generation spacecraft and lander, so as to realize manned lunar landing and establish a lunar base

at present, Russia has suspended the research and development of super heavy launch vehicles, which cost a lot of money, and the focus of rocket research and development has shifted to the & quot; Angara & quot- A5V The specific process is four rockets; Angara & quot- A5v launches manned spacecraft, upper stage of hydrogen and oxygen, lunar landing riser and upper stage of hydrogen and oxygen respectively. The manned spacecraft and lunar landing riser are connected in the earth orbit and upper stage of hydrogen and oxygen, and then they are sent to the moon orbit. Then the spacecraft and lunar mole are connected in the lunar orbit, and the lunar mole is the last step of manned lunar landing

Lunar exploration project is one of the 16 major national science and technology projects determined by the national medium and long term science and technology development plan (2006-2020). Since the establishment of the project, the National Space Administration has organized more than 2000 units and hundreds of thousands of scientific and technological workers across the country to unite and cooperate, gather intelligence to tackle key problems, complete six exploration missions with high quality and high efficiency, and achieve the goal of & lt; Six battles and six victories< the chang'e-5 mission was a complete success, successfully bringing the lunar ore and soil back to earth

return to the moon and walk in a dream. As a space system engineering with the highest complexity and the largest technological span in China, chang'e-5 mission has achieved many major breakthroughs in China's first lunar surface sampling and packaging, lunar surface take-off, lunar orbit rendezvous and docking, and re-entry and return with samples; Around, down, back & quot; The three-step plan was completed on schele
