Chapter 616

The moon is very close to the earth. In just over a day, zeus-2 spacecraft took tourists to the moon.

When people set foot on the surface of the moon, their hearts beat faster, and they were so excited that it was hard to describe!

"You can carry out free activities within 300 meters of the base. If you go beyond this range, you will receive a warning from SpaceX company in your headset. Please obey the rules when doing housework!" A guide said.

As soon as the words fell, people left in twos and threes and began to continue their journey of exploring the moon. After a while, they saw a tourist jump up and fly in the air. Seeing this, everyone jumped up one by one.

"Wow, my God, I can jump so high that I feel like I'm flying up!"

"Ha ha, that's the feeling of flying. It's amazing!"

"Oh, I'm Superman!"

“……”

From time to time, everyone's voice came from the headset.

At this moment, the national live app software is also playing their videos on the moon, and at the same time, their speeches can be heard. The number of viewers around the world is as high as 652 million!

Countless netizens are really envious.

"I wipe it. It's so cool!"

"Damn, I really want to go to the moon!"

"The most expensive travel in the world is really worth the money!"

"To see them flying around, we have to say that the earth people are actually very powerful, and they have become Superman on the other planet!"

“……”

On the other hand, the zeus-2 spacecraft is unloading food, genetically modified plant seeds, a large number of graphene materials and some advanced equipment.

With advanced equipment, local materials can be obtained, thus saving a lot of materials transported from the earth.

The first is to build a large area of closed base, and then in this closed base to create a more perfect ecosystem, which has water and oxygen circulation system, and then grow some crops, to achieve food self-sufficiency!

The moon's gravity is too small to have the ability to bind the atmosphere. Therefore, if there is no closed space, no amount of oxygen will leave the moon. Therefore, the base on the moon is destined to be built as a closed base.

Previously, SpaceX's base used graphene inflatable houses as temporary residences for astronauts, but this is not convenient and not conducive to the establishment of an ecosystem. What's more, Henry hopes to build a magnificent city on the moon, but the graphene inflatable house obviously can't satisfy his wish!

It's really difficult to build a huge barrier in the sky of the city.

How to build it?

Henry came up with one thing - a drone 3D printer.

Let the UAV fly into the air for 3D printing, and directly print out the graphene glass wall.

The main difficulties involved are the development of UAV 3D printer and positioning system. At present, on the one hand, it is the development of technology, on the other hand, it is the storage of materials. If we want to build a city as big as Shanghai, the materials transported by zeus-2 spacecraft can only be regarded as a drop in the bucket!

There is no graphite ore on the moon, and graphene glass is the best material to build urban barriers. First of all, graphene is almost completely transparent, absorbing only 2.3% of the light, so the remaining light can be used to make solar panels for power generation in the lunar city base; Secondly, graphene is so dense that even the smallest gas molecules can't penetrate it. Naturally, the oxygen in the closed space won't run out; In addition, graphene is the strongest and toughest material. Its fracture strength is 200 times higher than that of the best steel. It is not easy to break, and even if it is broken accidentally, it is only partially broken and easy to repair!

Henry is now talking with Dr. Dick Bart, CEO of SpaceX company, to discuss how to speed up the transportation of graphene glass materials.

"We all know that the biggest cost of interstellar navigation is to increase the speed. After zeus-2 goes to the moon, zeus-1 will return soon. When zeus-1 leaves the lunar orbit, it can still maintain a very high speed. If it is allowed to return to the earth's surface, it will undoubtedly reduce the speed to zero. When it is sent to the moon again, it will consume a lot of energy. Therefore, we can consider building a cargo transfer station in earth orbit, that is, a space port! First, the spaceport can be a base for the storage, replenishment, repair, supply, maintenance and launch of transfer spacecraft and on orbit mobile aircraft; Second, it will also be a transportation hub for passengers and equipment.

When zeus-1 arrives at the spaceport, we will send the money from the earth to the spaceship. When it leaves the spaceport, it can still maintain a high speed! In this way, the time for zeus-1 and cosmos-2 spacecraft to travel between the earth and the moon will be greatly shortened, perhaps only a few hours! " Said Henry as he thought.

Dr. Dick Bart praised Henry's idea!

"Your Majesty, your idea is very good. With the spaceport, the spaceship can not only save energy, but also not be damaged by the earth's atmosphere. The service life of the spaceship will be longer! Although SpaceX has mastered the rocket recovery technology, the rocket recovery must pass through the atmosphere again. We can let the rocket complete the mission, return to the spaceport, and then serve other spaceships! "

"Not only the Rockets of SpaceX company, but also the Rockets of other countries or companies can stay in SpaceX space port, which will inevitably reduce the launch cost of rockets, and the spacecraft will also have enough rocket propellers. It can be predicted that the completion of the space port will certainly speed up the development of space operations! "

Dr. Dick Bart's eyes brightened and said in a loud voice: "rockets from other countries or companies can't return to earth, but it's much easier to fly to SpaceX spaceport. It's a lot of money just to collect commission! Your majesty, I am sure that after the development of the spaceport project, it will produce unimaginable gains! "

"Yes, that's right!" Henry nodded, "and the spaceport will be the busiest platform for space trade in the future! The spaceships coming from other planets will not enter the earth, but directly complete the cargo transaction in the space port! "

Dr. Dick Bart nodded with approval and said to Henry, "Your Majesty, in my opinion, we can expand the SpaceX space station and build it into a space port!"

"Well!"

Henry pondered for a moment and said, "the main task of SpaceX company is to build a space port. As for the moon base, we can slow down the speed. After the completion of SpaceX port, we can go to the moon to build a huge city!"

"All right!"

(I've caught a cold. I'll get better tomorrow. I'll make it up in three chapters.)
