Uncle Sam has carried out many manned lunar landings in the 70s of the last world, starting from Armstrong's landing on the moon on July 20, 1969, Uncle Sam has carried out 6 manned lunar landings, and a total of 12 astronauts have landed on the moon.

You must know that this was in the 70s of the last world, and half a century has passed since now, so it can be seen that Uncle Sam's scientific and technological level is definitely not covered, and this scientific and technological strength is very strong.

Of course, the manned moon landing in the last century, which cost a huge amount of money, was actually for the needs of the Cold War hegemon, and for the promotion of Uncle Sam's own powerful scientific, technological, economic, and military strength.

The Apollo manned moon landing program spent a total of tens of billions of dollars in huge funds, and some people may think that tens of billions of dollars are not a lot now, but this time has to be pushed forward by 50 years, the time was in the 70s of the last century, when the American knife was called the American knife, and the foreign exchange reserves of the entire China at that time could not take out hundreds of millions of dollars, and it was very poor.

At that time, it can be said that it was a swollen face and a fat man, and the investment cost was huge, but it did not have much substantive significance, except for bringing back some rocks and soil on the moon for the study of lunar resources, there was not much real effect.

This is also why in the next half century, Uncle Sam did not carry out manned lunar landing activities, not because Uncle Sam's technology has regressed, but because manned lunar landing activities are a loss-making business, and it is also a loss-making business, and the country controlled by businessmen is naturally reluctant to do this kind of loss-making business.

However, this time is different from the past, with the beginning of the space race in China, coupled with the fact that the current science and technology have achieved tremendous development compared with half a century ago, and with the establishment of a permanent lunar base on the moon and the exploitation of lunar resources.

Uncle Sam is naturally not to be outdone, not to mention that he now has the technology to mine lunar resources on the moon, whether it is out of the need for competition or out of greed for lunar resources, Uncle Sam has repeatedly increased investment in space technology.

The return to the moon plan is the most critical and core point, and Uncle Sam has been frightened by Huaxia's powerful space technology and rapid development speed, and he is afraid that this gap is getting bigger and bigger, even if it is difficult, he will have to keep up.

On October 5, 2020, here at the Uncle Sam Kennedy Space Center, the world's major media who heard the news surrounded the water, and the long guns and short guns were aimed at the tall "Saturn 5" carrier rocket on the launch site, which is 110 meters high, with a take-off weight of more than 3,000 tons, a total thrust of 3,400 tons, a lunar orbit carrying capacity of 45 tons, and a low-earth orbit carrying capacity of 118 tons.

The Saturn 5 launch vehicle is a multi-stage disposable liquid (solid) fuel rocket, and a total of 13 Saturn 5 launch vehicles were launched between 1967 and 1973, and they held a perfect launch record. A total of nine Saturn 5 launch vehicles launched the manned Apollo spacecraft into lunar orbit.

The production line for the Saturn 5 launch vehicle was closed in 1970. The last launch of the Saturn 5 launch vehicle was in 1973, and now Uncle Sam has rebuilt the Saturn 5 launch vehicle with many advanced technologies based on the original design scheme.

Its thrust and carrying capacity are more powerful than before, and its performance is superior, but the name is still "Saturn 5", because its history is so perfect, and Uncle Sam, like us, is also more superstitious about this aspect, so there is no need to use other names.

The tall "Saturn 5" carrier rocket stood quietly, and in the space command center, a huge world map had been unfolded at this time, all kinds of data were flashing, and at the same time, scientists in white coats below were busy one by one.

There was still half an hour before the launch time, and the president of Uncle Sam had already arrived, and was outside to preside over the departure ceremony for the astronauts this time.

"I'm very happy to be here, especially at this time, half a century ago, the president who has the same name as this space center, President Kennedy, he proposed a manned moon landing program, and in the end we succeeded in achieving this great goal, and we became the first great nation in the history of mankind to go to the moon."

"Half a century has passed, we have come to the first 20 years of the 21st century, and now we are also facing a more serious situation, someone has landed on the moon one step ahead of us, and has established a permanent manned lunar base on the moon, and even carried out mining and moon tourism on the moon."

"Countless people who love this country have written to me and sent me e-mails, asking me why we haven't worked hard until now, why we have been able to land people on the moon in the last century, but why we haven't returned to the moon again, and asked me if we are lagging behind."

"Today, I want to tell you, to those who love this land so much, that we are not only going to return to the moon now, but we are also going to have a permanent manned base on the moon, and in the near future, we are also going to develop the space industry......"

Uncle Sam's president delivered a stirring speech, and the audience continued to burst into applause, and countless Uncle Sam who came to watch recalled the glorious history of the past and applauded.

"Let us welcome our space heroes Alan Glenn, John Sheppard, and Gayn Collins ......with the warmest applause."

"We are here to pray that God will bless them and wish them all the best on their journey, and that when they return in triumph, our whole great nation will be cheered and proud of!"

The departure ceremony was very simple, a total of 7 astronauts under the watchful eye, boarded the tall "Saturn 5" launch vehicle, and soon arrived at the launch point, accompanied by blazing white flames, the huge carrier rocket took off and went straight to space.

Different from the Chinese manned moon landing, Uncle Sam's method is no different from the way of the manned moon landing in the last century, launching the spacecraft into space through a large carrier rocket, and the spacecraft orbiting the earth dozens of times to obtain greater initial velocity and then heading straight to the moon.

Then on the lunar side, a jet lunar spacecraft was used to land on the moon, and the lunar base was built on the moon, and the whole plan was very large, spanning a long time gradient.

In the plan, Uncle Sam will go to the moon every half a month or so to land on the moon in a manned spacecraft every half a month or so, and the purpose is naturally to build his own lunar base that can be manned for a long time.

And after the manned moon base is completed, Uncle Sam's side will also form a custom like Huaxia, with spaceships regularly going back and forth between the earth and the moon to transport supplies and astronauts, etc.

The total investment in the entire re-entry program is as high as 5 trillion US dollars, and it is not just as simple as sending a few astronauts to the moon to shovel a few catties of lunar soil and move a few moon rocks back.

Everything went very smoothly, the spacecraft was successfully launched into space, began to fly around the Earth's orbit, and the speed became faster and faster, and after a few hours, it directly left the Earth's orbit and headed straight for the moon.

In order to successfully complete the plan to return to the moon, Uncle Sam has already launched many unmanned probes, unmanned spacecraft, communication satellites, etc. to the moon in advance, and has also put a large amount of materials on the moon in advance, just like Huaxia, to lay the foundation for the manned lunar landing program.

"Uncle Sam's strength is still very strong, whether it is scientific and technological strength, economic strength, or military strength, everyone look at the Saturn 5 launch vehicle they used to launch spacecraft, as early as half a century ago, they were able to have such advanced technology."

"If it weren't for the fact that we had the space planes in our hands, it would not have been easy for us to surpass them in space."

At the Longling Town Aerospace Center, Li Fu looked at the picture monitored by the "clairvoyance" system, combined with the broadcast on the TV station, and the whole person couldn't help but give a thumbs up to Uncle Sam's scientific and technological strength.

"Well, the more I know about this field, the more I have to admire, in the traditional field of science and technology, Uncle Sam has indeed reached the pinnacle."

"This year, they are launching spacecraft every week to transport a huge amount of supplies into space, and through unmanned spacecraft and so on, they will transport a large amount of supplies to the Moon's Wells region, which is very close to the lunar equator, the terrain is gentle, and the resources are abundant, which is the most suitable area for them when they still rely on traditional rockets for transportation."

Chen Bin also nodded, as an expert in the field of aerospace, he naturally knew the entire detailed process of Uncle Sam's return to the moon, although Uncle Sam without an aerospace plane had very powerful rocket technology, it was definitely not as easy as Huaxia's side.

"Uncle Sam uses this traditional rocket to launch spacecraft, and the cost share is high, so it can be said that it is burned with money, and if you want to establish a permanent manned lunar base on the moon, Uncle Sam's cost will be tens of thousands of times that of us."

"The same single transportation of materials, they are not only costly, risky, the most important thing is that the transportation volume is too small, if the time comes to form a customization, there will be people to go back and forth between the earth and the moon on a regular basis, I estimate that Uncle Sam will not last long if it continues like this."
