Chapter 256 Mars Immigration Plan
However, in Liu Xiu's view, this was originally a good campaign to promote integrity that did not forget its original intention. However, it was exploited by some people with sinister intentions, and the result changed from good to bad, and Liu Xiu was naturally This is absolutely not allowed to happen.

With this skill, Liu Xiu naturally no longer has to worry about some people sabotaging his crops and stagnating his crops.

And after Liu Xiu successfully landed in space in 1963 and orbited it once, this space race with only two crops turned into the Romance of the Three Kingdoms.

Because Su Tuo was the first to land in space, this greatly stimulated Mi Tuo, so on May 25, 1961, Mi Tuo announced their Apollo manned moon landing plan.

So after Liu Xiu's space travel was successful, Liu Xiu began to suggest to the superiors that since Mi Tuo proposed a moon landing plan, then we must also propose a star landing plan. We cannot weaken Mi Tuo and Su Tuo. Since we have decided to join When this competition for hegemony comes, you have to show your own momentum.

Then after a period of discussion, after understanding that communication between Zao and Gao should not show weakness, under Liu Xiu's suggestion, the superiors announced a Mars immigration plan to the outside world, to occupy Mars and make Mars become Gao. The intention of harvesting the second planet.

Regarding this Mars immigration plan, when Mi Tuo and Su Tuo heard about it, they were first surprised and then laughed at it, saying that Liu Xiu was simply wishful thinking.

Liu Xiu naturally responded to this by launching another manned rocket the next year, but this time he directly carried three people into space at once and returned safely.

Because this proposal was proposed by Liu Xiu, Liu Xiu's Air Force at this time became the Aerospace Force. In addition to being responsible for fighter flight and training, it was also responsible for rocket launch training.

After all, it would be perfect for the astronauts to be selected from fighter pilots. There is no way anyone can let fighter pilots have experience in weightlessness!

Matching this, the manufacturing cost of the Falcon 9 rocket itself is as high as 50 million meters, so if the rocket itself can be recycled, this means that the cost of space transportation will be reduced to 10,000 meters per ton in the future. Knife, instead of tens of thousands of meters of knife per kilogram.

After all, the launch cost of a rocket that can be used multiple times is much cheaper than that of a rocket that cannot be used. Although a Falcon launch consumes hundreds of tons of fuel for one launch, the value of these fuels is only 200,000 meters. Just a knife.

The reason why Liu Xiu decided to build the Falcon recyclable rocket was naturally because Liu Xiu had already made a breakthrough from transistors to integrated circuits in computers.

And Liu Xiu did not just pursue the number of rocket launches, but began to learn from the Mosaic before time travel and started to make recyclable rockets!

Therefore, before Liu Xiu traveled through time, many people agreed that recyclable rockets were the basis for human exploration of the sky.

Therefore, I naturally have a lot of control over the thrust and attitude of the rocket engine. Of course, some fuel is needed to slow down the rocket when it is recovered, but this is not worth mentioning when it comes to recovering the rocket. .

However, it is different for Liu Xiu who directly set his goal on Mars, although Liu Xiu has already issued a plan to immigrate to Mars.

But Su Tuo and Mi Tuo thought this was wishful thinking, so they still set their goal on how to land on the moon. Liu Xiu, on the other hand, is actively thinking about how to land on Mars.

Of course, when Liu Xiu was thinking about the plan to wait for terrestrial Mars, he also referred to the four methods of landing on the moon proposed in the Apollo project.

The first method of landing on the moon was very simple and crude. It was to take off directly. A huge new rocket carried a spacecraft directly to the moon. The rocket landed on the moon. After the mission was completed, it took off again and flew back to the earth. However, this The planned super rocket was also more difficult to build, so the plan was eventually abandoned.

The second lunar landing method is the Earth orbit rendezvous method. This plan requires two small rockets only half the size of the Saturn V to send different parts of the lunar landing spacecraft into Earth orbit, assemble and dock. The entire spacecraft landed on the lunar surface. Since there was little experience in assembling multiple spacecraft in orbit at that time, and it was unknown whether it was feasible to assemble spacecraft in Earth orbit, this plan was not adopted.

Then there is the third one called the lunar surface rendezvous plan, which requires two spacecraft to be launched: an autonomous spacecraft carrying a propulsion system to land on the moon first; a manned spacecraft to be launched later. The propulsion system was moved to the manned spacecraft on the lunar surface, and then returned to the earth. However, this automatic moon landing is also more difficult to achieve, because it will be difficult to achieve if the two spacecraft land too far apart, so this plan is was abandoned.

The fourth plan is the lunar orbit rendezvous method adopted. This method uses a larger spacecraft, called the service module, to carry a lunar landing spacecraft carrying astronauts, called the lunar module.

The service module carries fuel and necessities from the Earth to the moon and back, as well as the heat shields needed to enter the Earth's atmosphere. After entering lunar orbit, the lunar module separated from the service module and landed on the lunar surface.

The service module remains in lunar orbit. One of the astronauts it carried remained in the service module in lunar orbit. After the moon landing, the lunar module took off again, the service module assembled in lunar orbit, and returned to Earth.

This lunar orbit intersection method is different from several other plans. This plan only requires a very small spacecraft to land on the lunar surface, which greatly reduces the mass of the spacecraft that takes off on the moon when it returns. By leaving part of the lunar module on the moon, the take-off mass of the lunar module was again reduced. The lunar module itself is divided into two parts, including the landing part and the take-off part. The former is used to land on the moon, and the latter takes off to rendezvous with the service module and return to the earth after the mission is completed. Due to the reduced mass of the spacecraft, only a single rocket launch is required for a mission.

The difficulty of this lunar rendezvous method is the problem of rendezvous in the lunar orbit. After all, the space station has not yet been developed at this period, and everyone still does not have much technical experience in the rendezvous of two spacecrafts in orbit. However, facts have proved that this fourth plan is successful. .

However, after Liu Xiu consulted the four plans in the Apollo project, he did not choose any of them. Instead, he planned to use the second and fourth plans together.

In Liu Xiu's vision, the first is the earth orbit intersection method. In fact, to put it bluntly, it is to establish a large-scale mobile space station, or a spacecraft, in the earth orbit.

Through multiple batches of rocket launches, a large space station is built in the earth's orbit, and then the items and materials needed for Mars landing, as well as the Mars landing module and return module are put into this space station.

When the preparations are complete, the thrusters in the space station can be started to accelerate the space station out of the earth's orbit and fly towards Mars.

Since the space station itself has speed, it naturally does not need to consume too much fuel and thrust to accelerate it to the point of leaving the earth's orbit.
