The US moon landing rocket is delayed again. Why did NASA, which landed on the moon half a century ago, lose its ability to land on the moon?
The launch of the U.S. lunar rocket has been delayed again. This result should not be surprising to everyone. The only thing that is more curious is why the United States lost its ability to land on the moon? The new US return to the moon plan is named Artemis, which is similar to the Apollo manned lunar landing plan half a century ago. It mainly includes six major parts, and the ultimate goal is to establish a base camp on the moon. In addition, there are also the establishment of a lunar orbital space station and so on. But the premise of all this is to have an easy-to-use "vehicle". Half a century ago, the Apollo manned moon landing used the Saturn V high-thrust launch vehicle, and the predecessor or technology of this rocket was based on V2 Missiles, after World War II, the United States received many technical personnel who defeated Germany, and laid a certain technical foundation. Looking at the space race of the last century in turn, the Soviet Union tried every means and failed to achieve a manned moon landing. The fundamental reason was the lack of a carrier rocket with high safety. In the last century, the United States carried out six manned moon landings from 1969 to 1972, sending 12 astronauts to the lunar surface, mainly relying on the Saturn V high-thrust launch vehicle. In 1972, Apollo 17 completed the last manned mission to the moon, ending the lunar landing program, and the expensive Saturn V carrier rocket was also retired. Now if you want to use it, you can't make it. First of all, the technical files have been lost. , many of the corresponding production lines have long been gone, and to put it bluntly, the Saturn V can no longer be produced. Successful manned landing on the moon requires a new manned spacecraft, and the first link of the plan to return to the moon is the development of super rockets, that is, the "Space Launch System" (SLS) that we have seen more than once delayed launch. ). This super rocket evolved from the retired space shuttle and has a very strong carrying capacity. But now its first step is "can't take it". Just recently, it has delayed the launch three times, mainly due to the suspected failure of the launch engine. Of course, this third delay, according to NASA's announcement, is mainly to avoid Tropical Storm "Ian", and the staff is ready to push the 'Space Launch System' (SLS) rocket and 'Orion' spacecraft back to the assembly building. . If this super rocket is removed from the launch pad and the assembly building of the Games, its launch time may be delayed even more, the first flight of the launch vehicle will be difficult, and the real manned moon landing will be delayed even more. I wonder if everyone feels another problem: the United States easily landed on the moon half a century ago, but why has it lost its ability to land on the moon now? In the people-oriented era, the launch of probes needs to pursue absolute safety, as is the case with launch vehicles and manned spacecraft! In the last century, the US manned moon landing was carried out in the context of space hegemony. In fact, the scientific purpose at that time was not so clear. Even the collected lunar samples were not completely preserved as good things, except that some were used as gifts. to other countries. In fact, the manned moon landing at that time was to completely suppress the former Soviet Union in the field of space exploration. I have to say that the effect was very good. But now it is different and must be people-oriented. To put it bluntly, it is for the safety of astronauts' lives and property, and the safety factor must be high. If it was placed more than half a century ago, this super rocket might have been launched long ago. A super rocket has been delayed nearly 20 times in the past few years. We are currently unable to determine when it will be launched. If this first step cannot be completed, then the real return to the moon and manned landing on the moon is far away. Many netizens said: The United States has lost the ability to manned the moon! In fact, judging from the current performance, it is true that there are frequent problems, but according to the overall mission plan, the United States will most likely be the country with the first manned moon landing in this century, and the first manned moon landing may be completed around 2025. Although the launch has been delayed repeatedly, NASA's capital can really be eaten for a few years. After all, the accumulation of technology is still sufficient and stable. But in the future this position may not be able to keep it! In terms of collecting samples from Mars in the next few years, China Aerospace is likely to be ahead of the United States. All this is due to the spirit of exploration that is steady and steady. Whether the lost moon landing capability of the United States will be quickly picked up again depends on the follow-up development. At present, the first step of returning to the moon is very bumpy, and there will be many difficulties in the future that need to be overcome one by one. , in the end is a flat horse or a bloodbath, let's wait and see?
