1. The United States is self-inflicted
The once mighty US space agency has now had to ask China for cooperation in obtaining samples taken by China on the moon. All this stems from the "Wolff" clause formulated by the United States itself 12 years ago, which prohibits any form of cooperation with the China National Space Administration. However, today's U.S. space community has seen the unique value of the lunar soil samples brought back by Chang'e-5, but it is difficult to bypass this clause. They can only reap the consequences of their own efforts and bow to China for results.
2. The arrogant mentality of the United States
The Americans, apparently forget, gave China only 1 gram of lunar soil sample when the United States landed on the moon for the last time in 1972. Now they want to work with China, but they are only willing to make "exceptions" to the Chang'e-5 sample and ignore other space programs. This arrogant attitude can only be ridiculed and ignored in the values and morals of the Chinese. If the United States really wants to cooperate, they should first reflect on their own behavior, instead of blindly demanding.
3. The United States has lost its chances
The U.S. astronomical and aerospace communities are very unhappy with the "Wolff" clause, but it has become extremely difficult to repeal it, especially in the context of the current tensions between China and the United States. While some have proposed repealing the provision, it has faced strong opposition from Republican lawmakers. Since the provision was enacted in 2011, China's space industry has grown rapidly, from manned spaceflight to resident astronauts on the space station to lunar soil samples brought back by Chang'e-5, every achievement has made the American scientific community envious. However, it is ironic that the United States has not only lost the opportunity to cooperate with China, but has also had to ask for China's help.
1. It is different from the lunar soil area collected in the United States
The lunar soil samples brought back by Chang'e-5 were collected from a completely different region than the lunar soil collected in the United States, which means that these samples are of unique scientific value. By studying these samples, scientists can further understand the geological structure and chemical composition of the Moon, thus providing an important reference for future space exploration.
2. Progress dating back to 1972
1972 was the last time the United States landed on the moon, and Chang'e-5 brought back lunar soil samples for the first time in nearly 50 years before a human lunar exploration spacecraft returned from the moon. This time interval makes these samples of special historical significance, and gives scientists the opportunity to trace and compare changes between the Earth and the Moon since 1972 to better understand the evolution of the Moon.
3. It is of great significance to the study of the origin and evolution of the solar system
Lunar soil samples are one of the oldest materials in the solar system, and the study of them can reveal the origin and evolution of the solar system. These samples may contain tiny mineral particles or organic material from other celestial bodies, and studying their composition and structure can help scientists better understand the formation and evolution of the solar system.
4. The guiding role of the protection of the earth and future space exploration
By analyzing tiny mineral particles and organic material in lunar soil samples, scientists can learn about the moon's special environment and surface characteristics. This will play an important guiding role in future space exploration and human lunar landing programs. In addition, the study of lunar soil samples can also help to protect the earth's environment, for example, by studying the harmful elements and environmental factors in lunar soil samples, which can provide reference for environmental protection and sustainable development on the earth.
1. Theft of technological achievements
U.S. politicians have long believed that China's space development and achievements stem from the theft of U.S. technological achievements. However, this perception is one-sided and biased. The rise of China's aerospace industry is inseparable from its own efforts and continuous investment, and it has made innovations and breakthroughs in many aspects. The pride and prejudice of the United States only made them miss the opportunity to cooperate with China.
2. Control of China's aerospace
The United States** may also try to control China by cooperating with China in space. They want to limit China's space development through the "Wolff" clause in order to maintain their leading position in the space field. However, China has demonstrated its strong aerospace strength and potential, and will never give up on space development because of such restrictions.
3. Take advantage of the international recognition of China's aerospace
The United States may also hope to gain international recognition and acclaim through its cooperation with China's space industry. China's space achievements have attracted widespread attention and appreciation from the international community, and cooperation with China can increase the international reputation and status of the United States. However, this kind of "exploitation" will not be recognized and supported by China.
In short, the United States has expressed a strong interest in and desire for lunar soil samples brought back by China's Chang'e-5 spacecraft, but the motive behind it may not be pure. The rise of China's space industry has made the United States feel uneasy and threatening, and they are trying to limit China's development by various means. However, China's aerospace achievements are based on its own efforts and innovations, and will not stop developing because of US restrictions. In the future, China's aerospace industry will continue to work hard to make more contributions to mankind's aerospace industry.
