1: Landing on the moon may be unpredictable.
2. The United States, Russia and other countries announced that they would stop the moon landing plan.
At present, we don't know enough about all aspects of the moon.
After Apollo landed on the moon, many questions were left.
One: China landed on the moon;
Chang 'e-3 probe was launched in xichang satellite launch center on February 2nd 1: 30. This time, "Chang 'e III" will take the "Yutu" lunar rover for the first time to realize the lunar soft landing and lunar patrol survey in China, and carry out scientific exploration such as lunar surface morphology and geological structure survey for three months.
After the name of Jade Rabbit was announced, China News Service sent back a message from Houston, USA, saying that on July 20th, 1969, the American Apollo1spacecraft carrying out the first human moon landing mission had an interesting conversation with the ground command center in Houston-"Please pay attention to a lovely big rabbit girl, and the legendary China beauty Chang 'e has already. "Ok, we will pay close attention to this rabbit."
When the island ice wheel started, I saw the Jade Rabbit rising again.
At this time, Xinmin Weekly learned from the relevant insiders of Shanghai Aerospace Technology Research Institute that China has made major adjustments to the lunar exploration project and even the entire space planning, and the original preparations for manned landing on the moon have been suspended. The current lunar exploration plan will be-"Chang 'e III" will reach the moon; As Chang 'e IV has been put into production, it will be launched as scheduled. In the future, it will complete the simulated manned landing on the moon, collect samples and then return to Earth. The expected "Chang 'e V" will stop research and development. The lunar exploration program will come to an end.
China cancels manned moon landing plan As far as China's space master plan is concerned, the lunar exploration project is divided into three steps, that is, the third phase of the plan of "returning around the moon" will be completed, and by 2020, the lunar exploration, landing on the moon and unmanned sampling will be completed in turn.
From June 5438 to October 2007 10, China's first lunar exploration satellite "Chang 'e-1" was launched on the Long March 3A carrier rocket, which made China's first lunar exploration trip and achieved its lunar exploration goal.
On 20 10, 10, Chang' e II took off on the Long March III C carrier rocket, completing some key technologies to verify the soft landing of the moon for the Chang' e III mission, carrying out high-resolution imaging of the Hongwan landing area of the pre-selected moon on Chang' e III, and continuing to carry out lunar scientific exploration and research. The launch of Chang 'e III was completed on the basis of previous launch results.
The white paper "China Aerospace in 20 1 1 year" indicates that China will select limited targets and carry out deep space exploration activities step by step. Then, as the first step of deep space exploration, how will China's lunar exploration project go after completing the "going back" mission?
20 10, on the occasion of the success of the "Chang 'e II" lunar exploration, Ouyang Ziyuan, chief expert of China's lunar exploration project and academician of Chinese Academy of Sciences, said: "The south pole of the moon is expected to be the landing point for manned landing on the moon. According to three possible timetables for manned landing on the moon, China's manned landing on the moon may be realized as early as 2020. "In fact, as early as 2006, Ouyang Ziyuan said that China would complete manned moon landing around 202 1 2025.
20111kloc-0/On October 25th, Ye Peijian, the commander-in-chief and chief designer of the lunar exploration project and Chang 'e-1 system and academician of China Academy of Sciences, delivered a speech in Nanjing. At the same time, he said that China's manned moon landing program may be realized around 2025.
Strangely, however, Ouyang Ziyuan, who was invited to attend the Lanzhou Yellow River Mother Cultural Park project conference in Lanzhou on October 9, 20 13, changed his mind when interviewed by reporters. He said: "The implementation of unmanned lunar exploration will accumulate technology and experience for China's manned moon landing and lunar base construction, but there is no exact timetable for China's manned moon landing program."
In fact, as early as May 2008, when Ouyang Ziyuan, known as the "father of Chang 'e", visited the lecture hall of social sciences organized by Jiangxi Social Science Federation, he asked the audience, "When will China achieve manned landing on the moon? He once said: "At present, there are many legends. Some say that China people can put a man on the moon in 2020, while others say that in 2025 and 2030. The time was also published online, but in fact, the specific time was not announced. "
From 20 10 clearly stated that "it may be realized in 2020 at the earliest" to now "there is no clear timetable", why didn't the preface follow?
Insiders of Shanghai Institute of Aerospace Technology revealed to Xinmin Weekly that the planned manned landing on the moon had been cancelled after the completion of the "detour". Insider analysis: "This is a major adjustment made by China's space industry."
In fact, as early as 2007, Luan Enjie, an academician of the China Academy of Sciences, the chief commander of the Chang 'e project in China, the deputy chief commander of China's manned spaceflight project and the former director of the National Space Administration, said that China would not send a man to the moon for 20 years. Not surprisingly, Chinese astronauts should have landed on the moon after the 1930s.
Facing the launch of Chang 'e-3, Spanish newspaper El Pais said: "Although many space powers put the moon landing plan aside, China, an emerging power, regards it as a main goal. Chang 'e III is an unmanned lunar probe, but China plans to prepare by sending back lunar samples to Earth in the next few years, so as to launch manned lunar probes in the next 65,438+00 years. "
No matter whether or not the manned moon landing plan is implemented, no matter when the manned moon landing plan is implemented, the difficulties faced by manned moon landing are enormous.
Zhuang Fengyuan, a professor at Beijing University of Aeronautics and Astronautics and an academician of the Department of Space Life Sciences of the International Academy of Astronautics, said in 2007: "The moon belongs to the category of deep space exploration, and astronauts have to be in a vacuum state and under the gravity of 1/6 state for many days. These problems need to be solved, and special drugs should be developed to ensure their physical condition. We have not studied this step yet. "
Zhuang Fengyuan once said: "With the advancement of lunar exploration, some research related to the lunar base will be gradually carried out. For example, when we build a lunar base, we need to raise plants and animals on it, and we can use a closed ecological circle to simulate the environment. The United States conducted a completely closed Biosphere 2 experiment (a closed ecological environment completely isolated from nature, like a big cover, in which plants and animals form their own ecological balance), which lasted for more than a year, while China did not. I want to suggest to the country.
From the Twelfth Five-Year Plan to the end of 20 15, more than half of the time has passed, and China has not released the research similar to Biosphere 2, which proves on the other hand that it is too early for China to send a man to the moon.
Let's see the significance of exploring the moon. The "Apollo Program" of the United States was completed during the Cold War between the United States and the Soviet Union. At that time, the competition between the United States and the Soviet Union in the space field had reached a white-hot stage. The success of manned landing on the moon, as astronaut Armstrong said, "this is a small step for individuals, but a big step for mankind." However, after "Apollo 17" returned to Earth on 1972, NASA never carried out the mission of landing an overloaded man on the moon. On that occasion, "Apollo 17" brought back 1 10 kg of moon rocks and soil samples.
Although Spain's El Pais shouted: "In recent years, NASA's space program has been erratic due to lack of funds. China, on the other hand, made an effective moon landing plan with huge investment. This situation is reminiscent of the space war between the Soviet Union and the United States half a century ago. "
However, China has never admitted to competing with the United States in the space field. For example, Wang Zhaoyao, director of the China Manned Space Engineering Office, has repeatedly stated that the development of China's space industry is progressing steadily in accordance with the established plans and predetermined goals of the China government. "We don't want to surpass any country or compete with anyone. We just want to meet our domestic needs. We go our own way and there is no competition with anyone. "
The photo shows that1On July 20th, 969, American astronauts Armstrong and Aldrin landed on the moon in Apollo 1 1 spacecraft. This photo was taken by their companion Collins over the moon through the window of the command module.
At present, the most practical significance of the lunar exploration project is the human energy dream. After all, the moon can provide many materials for energy "relay", such as solar energy, because the air of the moon itself is very thin, so it can directly use solar energy; For example, Helium 3, a clean and safe controlled nuclear fusion fuel that can be used for a long time, is said to have a reserve of 6,543,800+tons to 5 million tons on the moon, and dozens of tons of Helium 3 can maintain the energy demand of the earth for one year.
This abundant energy is of course very important to the earth where energy is gradually exhausted.
Apollo 17 only brought back 1 10 kg from the moon while completing the last manned landing on the moon. Yu Zeng, deputy director of the Science and Technology Committee of China Aerospace Science and Technology Corporation and deputy chief designer of China's lunar exploration project, said: "The third phase of China's lunar exploration project will collect lunar soil and return to Earth." In the future, "Chang 'e IV" can realize the automatic inspection of robots on the moon.
