Why must the United States send astronauts to the moon within five years?

China’s Chang’e lunar exploration program has been progressing steadily. Chang’e 4 has successfully landed on the back of the moon and obtained a lot of key data. It is the first country to soft-land on the back of the moon and has completed many U.S. missions. Things that were not done. Chang'e-5 will be launched around the end of 2019. The mission of Chang'e-5 will be to land on the moon and bring lunar samples back to Earth. China plans to achieve a manned moon landing around 2030. 2030 is an interesting node, because around this time, many countries will express plans to land on the moon. Russia and Japan are also planning to carry out manned landings on the moon in 2030. India is expected to launch a manned mission to the moon in September. A lunar probe is launched near the south pole of the moon. If the probe lands successfully, it will be the first time a human probe has landed on the south pole of the moon. Last year, US President Trump said he would launch a plan to return to the moon. Some time ago, US Vice President Pence announced that the United States would land on the moon again within five years. All countries are confident in their moon landing plans, and it feels like a new round of space race has begun.

The United States has announced that it will return to the moon within five years, but can it be achieved? 50 years ago, the United States successfully completed the feat of landing on the moon and has never been able to land on the moon again. The moon landing that year has always been suspected of fraud. There are many doubts about the entire moon landing. For example, the film temperature of the Hasselblad camera used for shooting could not be used normally on the moon, but many precious photos were taken at that time. There is also the return process of the lunar landing module. Many netizens believe that the return process was impossible with the capabilities at that time. After the source code of the moon landing was released on Github, it attracted the worship of many friends. When the Apollo program began in 1961, integrated circuits had just been invented for two or three years, and computers were still huge objects that filled a room. Installing computers into the spacecraft was one of the ultimate challenges at the time. In the end, the navigation module shrank to about 32 kilograms. This navigation computer It uses tens of thousands of parts and is assembled manually by thousands of people. Now any mobile phone has tens of thousands of times the computing power of that time. It is indeed incredible that the Apollo moon landing process relied on these patchwork computing hardware to achieve the landing and return process.

The United States has announced that it will land on the moon again within five years. I feel a bit skeptical. When this scale is expanded to about 10 years, I feel that it is about the same. The most important thing is that the United States currently does not have enough thrust rockets to achieve the entire manned moon landing and Return to plan. The Saturn 5 launch vehicle supported the entire Apollo moon landing program 50 years ago, and its production line was closed in 1970. The last launch of the Saturn 5 was in 1973. The Saturn V has a low-Earth orbit carrying capacity of 118 tons and a lunar orbit carrying capacity of 45 tons. However, the current high-thrust rockets in the United States do not have that much thrust for the time being. SLS-8 will not be able to achieve manned missions until August 2027. Therefore, it is still very uncertain whether the United States will return to the moon again within five years. Although integrated circuits, computers, materials and other technologies have made great progress in the past 50 years, the high-thrust rocket technology that plays a key role has not advanced enough. So after five years, we still only talked about it. I feel that our Chang'e project is still relatively reliable. Everything is going smoothly and the launch success rate is 100%. I really hope that the Chang’e manned moon landing will be successfully implemented in 2030.
