Chapter 399: Hardworking cleaners

Li Hao saw that the employees of Universe Exploration Group were very happy. He could also feel their joy.
It's not easy to get the shuttle to space safely for the first time.
Zhou Yunsheng saw the employee's surprise performance. She looked at Li Hao and asked strangely, "Hao brother, why are they so happy. The space shuttle hasn't just flew out of space, and it hasn't returned yet. It's too early."
Li Hao said with emotion: "It wasn't too early. They had a reason to be happy that they could safely send the space shuttle out of the earth. This test flight was a perfect success.
I have very low requirements for the space shuttle's test flight, which is to safely send the space shuttle out of the earth. Verify that its engines and enclosures meet design requirements.
Now the major powers in the world, the success rate of their first launch of a new spacecraft is only 30%. The success rate of subsequent launches was only about 50%.
Industrial products have a process of gradual maturity. No product is no exception.
Due to different systems, China Xia ’s launch success rate is somewhat high. But it is not as high as people think.
The highlights of the launch scenes we saw on TV or on the Internet.
This cannot be said to be a space mission, but has risen to a political mission. It is absolutely over-invested, planning every detail through long-term arrangements. To ensure the successful completion of space missions.
Our space shuttle acts as a new type of spacecraft. It successfully ignited and successfully flew out of the earth during the first test flight. This is extremely difficult. "
After Zhou Yunsheng heard Li Hao's explanation, she nodded her head to show understanding.
See the space shuttle soaring in space. Li Hao They were sitting on chairs, chatting with Guazier and drinking juice.
Director Qiu Shi asked, "Chairman Li, your space shuttle has flew smoothly out of the earth. I would like to wish you success here first.
When a normal space mission arrives here, it enters the orbit scheduled by the spacecraft in advance. The orbit runs for a few days and a few hours.
I see when your space shuttle just flew out of space, its largest engine started to ignite. Seeing the target orbit shown on the light curtain, it should be a geosynchronous orbit.
What does your space shuttle do in geosynchronous orbit? "
After Qiu Shi finished speaking, he relaxed his mind and waited for Li Hao to answer like a story.
The secretary sitting next to Qiu Shi didn't seem to care. But his eyes flickered, staring at Li Hao with the light from the corner of his eyes. Waiting for his answer seriously.
"I don't know what the space shuttle will do? Maybe verify the technology." Li Hao replied with a smile and waved his hand.
At the same time, he turned to look at Ma Yiming who was staring at the big screen.
Ma Yiming felt that Li Hao was watching him and responded: "The space shuttle is indeed flying to more than 36,000 kilometers of geosynchronous orbit. His main task is to go up to clear space trash."
He mentioned the task of clearing space trash, and everyone was thinking about space trash. They are no strangers to the word.
Space junk is a useless man-made object that orbits the earth.
Space junk is as small as satellite debris, paint chips, dust, and the entire wreckage of the spacecraft.
Electronic synths sounded in everyone's ears. By special means, the sound is confined to their area.
"Since the former Soviet Union launched Sputnik-1, the world ’s first man-made satellite, countries around the world have performed more than 4,000 launch missions, generating a large amount of space trash.
Although most of them were burned by falling into the atmosphere, as of last year, more than 4,500 tons of space debris remained in orbit.
Space junk generally moves in low-Earth orbit at a height of 300-450 kilometers and moves at a high speed of 7-8 kilometers per second.
In geosynchronous orbit at an altitude of 36,000 kilometers, it moves at a high speed of 3 kilometers per second.
According to the relative speed of the orbital inclination collision, the space debris collided with other spacecraft, and the relative speed produced could even reach more than 10 kilometers per second.
Because of the tremendous kinetic energy of the collision, the collision of space trash with other objects produced a huge destructive force.
Therefore, if space debris collides with a spacecraft such as an artificial satellite, a manned spacecraft, or the International Space Station in operation, it may cause damage to the machine, and endanger the life of the astronaut.
It is calculated that a space junk with a diameter of 50 cm can destroy the space shuttle.
A few millimeters of space junk can cause damage to the internal structure of the space shuttle if it collides. "
Director Qiu Shi said with a smile: "President Li really has the international spirit and expends so much energy to clean up the space trash that is extremely troubled internationally. This is a very kind act."
"You might as well just say that I am the Virgin White Lotus. We capitalists rarely have free time to help others. This is also no way." Li Hao said with a bitter smile.
He couldn't admit it, not to mention that it wasn't for that purpose.
If he really fame, promise to come down. Director Qiu Shi will definitely take the opportunity to come up with a formula for sharing the strength-type strengthening fluid, so that this technology can serve more people.
He already knew the cheekyness of these people climbing up.
Li Hao explained briefly: "The mission of the Space Shuttle is to clean up space trash. It is not that we want so much, but that we have to do so and have no choice.
If there is a pile of on the road in front of our house that can damage the vehicle, everyone else rides a bicycle, occasionally once or twice a year. As long as he is skilled enough, he can avoid hitting garbage.
We are driving a luxury car and we drive out almost every month. You say who will clean up the garbage. "
Everyone immediately understood what Li Hao meant. Now mainstream countries are conducting space activities a long time apart. Mainly launch satellites.
The Space Exploration Group will definitely launch space shuttles frequently in the future. From a probabilistic point of view, it is also the probability that the Space Exploration Group will encounter a space garbage accident.
The secretary sitting next to Qiu Shi suddenly said, "This shuttle is too fast, and that large engine is also very powerful. It only took us a few hours to reach geosynchronous orbit from outer space."
I only saw the space shuttle's simulation animation in space.
Just a bunch of space junk was moving towards the space shuttle's position at high speed.
Only the space shuttle ejected a large two-dimensional black net from the cabin.
Ma Yiming said: "This net is made of a special two-dimensional thin film material. It is extremely tough and can withstand thousands of kilograms of pulling force.
Our purpose is to use this two-dimensional large net to wrap up space trash, so that many space trash can be brought together.
Due to the gravity of the earth, this garbage will gradually be pulled towards the earth. Finally burned in the atmosphere.
The two-dimensional large net has its own power, and its propellant is stored in a liquid form in a gap of 10 microns in width between the two films.
Can provide weak power, which can make extremely complex movements in the vacuum environment in space.
A two-dimensional large net with a size of 100 square meters weighs about 0.5kg. UU Kanshu www.uukanshu.com is very convenient to store and use.
It can be clearly seen in the animation that this large net was ejected, and the thruster immediately acted according to the pre-procedure.
A net was curled up, and the propellant was immediately activated. The entire net was stretched and flew forward. It's like a spider web ready to hunt.
Quickly came to the edge of space junk due to being hit. The two-dimensional large net is naturally closed to the rear. Space junk was quickly wrapped up.
Seeing this scene, Ma Yiming exhaled and said easily: "Our design is really successful, and we can use it to efficiently clean up space trash.
The clean space environment is especially conducive to our company's space shuttle moving between orbits or placing some satellites on certain orbits. "
They continued to visit this ground command center, and everyone was worth it.
The space shuttle acts as a hardworking cleaner. Cleaning up most of the space junk in Earth orbit.
