The reason is that the technology is immature. With the emerging space power represented by China, no matter in lunar exploration, Mars exploration, space station construction, etc. They have continuously achieved feats that shocked the world and greatly threatened the right to speak in the space field. Under great pressure, the United States approved the implementation of the "Al themis Plan" to land on the moon in 20 17, and has been making various preparations and experiments in recent years.
However, the news shows that the Al themis/KLOC-0 rocket originally scheduled to be launched this year was forced to be postponed again after many delays, and the reason given by NASA was that the technology was not mature. As a result, many speculations about the fraud of Apollo manned landing on the moon in the United States in the last century were once again hotly debated by netizens. Among them, the most important issue is that manned rockets can be launched more than 50 years ago. How can technology achieve "no progress or retreat" now?
According to the data of Wisdom Bud, NASA and its affiliated companies have 9,730 patent applications in 126 countries/regions, almost all of which are invention patents. Generally speaking, the more invention patents a company has, the stronger its R&D strength in this field. According to the company's patent target market countries, the company's main technical target market countries are the United States, accounting for about 50%, and the rest are Germany, Britain, Japan, France and other countries.
In addition, according to the technical composition of the company, 22. 18% of its patents are related to reactor fuel elements and their components, 1 1.46% of its patents are related to reactor types, and1.14% of its patents are related to reactor types.
According to the current proportion of scientific research investment, the United States needs to spend at least $654.38+02 billion on the moon landing program, and the latest statistics show that in 2020, the United States will only invest $565.438+08 billion in space activities, and even less funds will be allocated to the moon landing activities. Considering the inflation problem, the investment of the United States in the field of landing on the moon is far from that of the Apollo program, and it is reasonable that it will not be able to return to the moon in the short term.
