In the early morning of the 8th, the space shuttle, which has been operating in space for three days, after it cleaned up space junk near the Earth's orbit. Will be returned to Earth in accordance with established procedures.

Li Hao and Ma Yiming stood on the airport in the cold wind, waiting for the landing of the space shuttle.

Soon, a bright light was seen in the dark sky.

At the same time, Niu Zhengfeng, who was in the ground command center, informed everyone.

"The departments are ready that the space shuttle has descended to an altitude of 20,000 meters above the ground. About to land on the ground. ”

Cosmos Exploration units welcomed the landing of the space shuttle. They've trained many times and now it's time to put their skills to the test.

Li Hao saw a figure the size of a swallow peeking out of the clouds. After that, it slowly grew larger, and its shape became more and more defined.

The shuttle got closer and closer to the ground, only to see a sudden flash of fire under the wings on either side of it.

The ionic electric propulsion engine, which originally had a rearward nozzle, rotated 180 degrees. Its spout rushed in the direction of the ground.

The ion-electric propulsion engine began to power the shuttle's deceleration, and the shuttle's speed decayed rapidly.

As the shuttle approached the ground, the ionic electric propulsion engine began to spin again. Its spout is perpendicular to the ground.

The shuttle landed lightly on the ground like a feather from the sky.

After Ma Yiming saw that the space shuttle was stationary, he immediately arranged for the company's employees to carry out all the equipment and items on the space shuttle.

Li Hao saw that these devices were all classified and carried out of the space shuttle in an orderly manner.

The equipment used to record the operation of the shuttle was carefully transported to the factory by engineers.

Engineers want to inspect the data of these devices. It provides data reference for future space shuttle operations.

Qingci Science and Technology Research Building, entrusted their company to send equipment and items to space.

The staff carefully loaded them onto the large drone and quickly began to airlift them back to the research building.

After unloading the equipment, they took the shuttle to the factory and thoroughly inspected the various components of the shuttle.

Li Hao saw that they were all busy, and the space shuttle also landed smoothly on the ground. He simply encouraged them a few words, and then drove to the scientific research building in a smart electric car.

He folded down the chair of the smart electric car to resemble a small bed. Li Hao lay on the bed and watched the time at one o'clock in the morning. Staying up late to this time, coupled with the technology of translating alien civilizations in the past few days, has not had a good rest. He's sleepy now.

He took the opportunity to sleep again. Put smart electric vehicles into self-driving mode and drive slowly on the road.

This space test flight will certainly yield a lot of results. At the very least, it has also verified the feasibility and maturity of the space shuttle's various technologies.

But if you want to get greater benefits, you still have to look at the laboratories in the scientific research building, and the technology that is placed on the space shuttle for verification. The value they bring will give higher added value to space activities.

Li Hao felt that his face was wet, and there was an itchy feeling. He wakes up to find his pet dog, Babe, licking his face.

He gently patted Beibei's dog's head, and Beibei snorted twice before stepping aside.

He opened his eyes and looked around. found Zhou Yunsheng standing at the door of the car looking at him.

Li Hao asked suspiciously, "Yunsheng, why are you here?" ”

Zhou Yunsheng looked at Li Hao's tired face, and she said with some heartache: "How good is it to wait for the result at home, you have to go to the airport to watch the space shuttle land in person."

Smart electric cars have long been parked at the door of the scientific research building, and you sleep to death because you are too tired.

The parrot has locked the vehicle, and others can't turn on the smart electric car. They had to call me to come over. ”

When Li Hao heard Zhou Yunsheng finish speaking, he looked at the time and said in surprise: "It's 8 o'clock in the morning now, have I slept for so long?" ”

He looked at Zhou Yunsheng's worried expression again, and promised: "In the future, I will definitely rest on time, this time it is not a special situation, I am afraid that there will be an accident on the space shuttle." I can also coordinate with various departments to deal with it. ”

"Let's go, I know you won't go back if you don't understand clearly." Zhou Yunsheng said helplessly.

Li Hao and Zhou Yunsheng walked towards the scientific research building, they first went to the bathroom to wash up, and then went to the canteen to have a simple meal.

He summoned the heads of the various projects in the research building to the conference room.

He waited for a while, and saw Du Xianyu, Bi Ye, and Guo Jianhao coming in in turn.

Li Hao asked them carefully: "What about the items or equipment you put on the space shuttle." They did not produce the intended results. ”

Guo Jianmiao's fingers moved, and a small box appeared in front of them. The box is melting the metal powder that has been proportioned.

In the vacuum weightlessness environment of space. The melted powder floats up and forms small balls.

After Guo Jianhao finished the shot, he explained briefly: "This is the project of our materials and chemistry laboratory experiments in space.

The practical verification of the space factory, judging by the results, it was a perfect success, proving that we can build factories in space.

This is the ultra-smooth material we studied, which is an alloy of common and polymetal.

The coefficient of friction between the material itself is very low, making it ideal for balls. Its coefficient of friction is equivalent to the friction between air. The coefficient of friction used in equipment is equivalent to magnetic levitation technology.

However, one of the characteristics of this material is that the alloy must be very evenly distributed. This material cannot be processed on Earth.

Due to the action of gravity, the metal powder is in the process of melting. Because of the difference in density, they produce a certain amount of upheaving and sinking.

In addition, the molten metal cannot form an absolute spherical shape, and must be polished. It destroys the properties of this alloy.

But processing in space completely solves this problem, and it is in a vacuum weightless environment. This ball is perfectly machined. ”

Li Hao heard Guo Jianhao's introduction, and he was very satisfied. From what he learned from the Alien Science Library, most of the special materials need to be processed in space.

Du Xianyu then reported: "We put plants and animals on the space shuttle just to verify the impact of the space shuttle on living organisms. No special experiments were conducted.

Through our observation of flora and fauna, we found that the materials of the space shuttle can effectively shield from cosmic radiation.

The organism lives in the shuttle for a short period of time and does not affect his physical condition. This time is best controlled within a year.

If a booster fluid is used, he can stay on the shuttle for a corresponding amount of time. ”

Bi Ye walked up and said helplessly: "We have placed a number of physical detectors, maybe the time is too short, and no valuable clues have been found.

Gravitational wave detectors, however, found a set of regular gravitational fluctuations. ”

After he finished speaking, he casually showed the gravitational wave data to everyone, and he thought that this kind of data was all too common everywhere in the universe.

Li Haoman glanced at the gravitational wave data absently.

His demeanor changed dramatically, his eyes bloodshot and his pupils constricted. The fists clenched involuntarily, and the body trembled involuntarily.
