After nearly 10 hours of flight, Yinglong began to slow down and prepared to enter orbit around the moon.

The two of them, who took turns to rest, both lifted their spirits at this time.

Let's be honest, if one is not done properly, or if the orbital data is calculated incorrectly, then the fun is great.

It's hard to imagine flying past the moon and coming back.

At this time, the two of them felt that their professional level was low. What if this happens?

The two only know how to follow the flight manual and operate accurately. As far as the roles of the commander and pilot of the spaceship are concerned, in addition to courage, discipline, and execution, the basic skills of the two are really a little different. 、

Fortunately, this task between the earth and the moon is indeed extremely safe for the abilities that Gu Song has mastered.

After decelerating for a certain distance, Yinglong adjusted its attitude and successfully entered the orbit around the moon.

Looking at the moon below, Zhao Ya said, "The two of us ...... I think the first two Chinese people came here. ”

Zhao Hongtao smiled: "Li Wei and Yang Haisheng, if they know, I don't know what it would be like." ”

"Head, you said come and pick up the express, how do you get it?"

Zhao Hongtao looked at the current orbit data, and then said: "The payload compartment is ready to open, and the countdown is 163 seconds." ”

Zhao Ya stopped gossiping, and prepared for the opening of the load compartment according to what she learned in the training.

In the space environment, if you want to ensure that there will be no problems, before the payload compartment is opened, you must ensure that the air pressure and temperature inside will not deviate from the space environment.

More than two minutes passed quickly, and the load compartment was opened. Now, there's more than one thing in the load chamber.

Under the automatic guidance of the mission's flight data, the robotic arm sends one of the spacecraft in the payload bin out of the payload bin.

The materials used in this robotic arm are specially crafted to move a wide range of loads weighing up to 50 tons quickly and flexibly in the weightless environment of space.

Now this spacecraft is not so heavy.

The robotic arm protruded a full 20 meters from the payload compartment, placing the spacecraft just 20 meters below Yinglong.

After a slight shock, the robotic arm released the spacecraft, and it flew there relatively stationary at the speed of the Yinglong.

Zhao Hongtao entered a series of commands, and the electromagnetic vector nozzle of the Ying Long began to work gently, adjusting the attitude of the Ying Long, and slowly pushing away from the spacecraft.

It seems that after the distance between Yinglong and it reached a certain limit, the spacecraft also began to work.

Thanks to the fact that it was still in visual range of the Ying Long, it could be seen that there were signs of thrusters working on it.

Zhao Ya asked, "Let it pick up the express?"

Zhao Hongtao nodded.

Zhao Ya couldn't help asking, "Here on the moon...... Why is there our ...... ...... 'express'?"

"The boss said that the satellites we launched to the moon in the past have borne fruit. ”

“…… Didn't they all fail?"

Zhao Hongtao glanced at Zhao Ya, and Zhao Ya understood.

It seems that like a secret mission, it cannot be known to outsiders. It turned out that at that time, the satellite launched by Flint Space to the moon did not fail.

Zhao Ya looked at the spacecraft that went to pick up the "express...... Forget it, let's call it the courier, it seems to be slowing down, and it quickly falls out of sight.

She looked back at the little bright spot on the gauge screen.

"So what do we need to do next?"

And so on. ”

Zhao Ya looked out again, and more than 100 kilometers below was the surface of the moon.

But now there is no courier in sight, no other exploration satellites, and no what's on the surface of the moon.

It was here that the Yinglong flew alone, circling the moon, round and round.

Compare to the earth...... Space is indeed very lonely.

……

After the "courier" left the Yinglong, he received the command, and the equipment on it began to activate.

At the same time, Gu Song, who was located in the underground laboratory of the Xiangshan Annex, also received synchronous status information.

Strictly speaking, the "courier" is indeed like a drone that picks up and delivers goods.

It's just that the technical content is completely different.

Now, the "courier" first slows down and begins to adjust his track.

It did come to pick it up.

What you take is important.

Flint Space City has been built to that scale, with an area unprecedented in solar panels. However, that amount of power generation is actually difficult to support the energy demand for the construction of the interior of the Flint Space City.

The outside world thinks that the interior of the flintstone space city is now as simple as the International Space Station.

However, the future of Flint Space City is to accelerate out of the Earth's orbit and rush to the frontier of the solar system. Although such a thing is the so-called interplanetary improvised spaceship mentioned in the "Encyclopedia of Astronautics Basics", structural strength is a must.

Therefore, after the outside pie is spread, the construction and renovation of the interior must begin.

In the core module that has been completed in the construction of the flintstone space city, there is naturally a key micro-fusion generator.

There is a power generation device, but there is no fusion fuel.

Fuel is on the moon.

The "courier" is the miniature factory that goes to the back of the moon to get the fuel that has been accumulated for so long.

Of course, it's too wasteful to just take fuel.

The "courier", of course, has its own cargo compartment.

The capacity of this cargo compartment is still very large.

The payload of Yinglong reached more than 70 tons, and the moon has a small gravitational pull, and it does not have a dense atmosphere like the Earth to form resistance, so it is much easier to take off from the surface of the moon.

So this time, the "courier" actually sent a lot of things.

One of them is a very special relay satellite.

Towards the perilunar point, the cargo compartment of the "courier" opened, and a satellite robotic arm sent out a cube.

Then, the "courier" quickly adjusted his posture and staggered away from the cube.

The cube accelerates, unfolds, and quickly disappears from view.

After several adjustments, it determined the final shape of the track.

It was the Earth-Moon Lagrange L2 point, and in order to implement the Flint Plan, after the Flint Space City, Space Mining, Yinglong, and the Moon Back Factory were completed, it was necessary to further ensure the stability of deep space communications.

The Queqiao relay communication satellite is in place ahead of schedule!

……

After the "courier" adjusted his track, he went straight to the back of the moon.

To retrieve the fuel sent to Flint Space City, the total mass is not much.

How much fuel can a spacecraft of the level of Flint Space City consume with the blessing of the most advanced form of fusion generator?

It's really a slap in the face, and a box of helium-3 is enough to bring it over.

Therefore, after getting the "express", it is not to add how many additional tons of mass to take off, but to unload the more than a dozen tons of goods that it now brings, and set off again with a light car.

Reaching the surface safely on the back of the moon is the only way to go.

After a long time, the miniature factory on the back of the moon has not changed dramatically.

It's just that under the hard work of the mini excavators, the places where their wheels press are getting bigger and farther away.

As a result, a large piece of flat land was cleared, like a landing pad.

No, if anything, it's the landing pad.

At each of the four corners, there is a small man-made object, which stops there and outlines a square.

The "courier" landed firmly in the center of the square.

The cargo compartment opened, and the side that was opened fell to the ground, creating a slope.

After making sure it was firmly parked, a small car-shaped thing came out of the cargo hold, and a cube was placed on it.

The cart transported it to the edge of the micro-factory.

The current micro-factory has received supplies for giant satellites and nine heart-shaped satellites, and has expanded some scale.

The main performance is that there are two more robotic arms.

Now, the two robotic arms first grabbed the cube sent by the small car and placed it in a position next to it. Then, the top of the cube opens first, and the robotic arm grabs a small box from it and places it on one of the tracks of the micro-factory.

The box went inside the micro-factory, and after a short time, it was sent out again.

The big mechanical arm, twisting a very small box, is placed on the platform of the small car, the scene is a little funny, like a giant, carefully holding a small steamed bun and placing it in his bowl like a big iron pot.

That's less than two kilograms of helium-3 in total.

The cart began to move back, and when it went uphill to the cargo hold, the box did not slide off the platform of the cart.

The cargo door was closed again, and at this point, the goods were delivered and the courier was picked up.

The courier kept going, and the thrusters began to spew light flames, blowing away a lot of moon dust and taking off into the air.

Strangely, the moon dust did not spread out of this landing pad.

It turns out that the four man-made objects that outline the square actually cut off a three-dimensional space.

The "courier" began to look for his own flight, the Yinglong.
