Chapter 399: Industrious Cleaner

Li Hao was very happy to see the employees of the Space Exploration Group. He could also feel their joy.

It was not easy to get the space shuttle into space safely for the first time.

Zhou Yunsheng saw the unexpected performance of the employees. She looked at Li Hao and asked strangely, "Brother Hao, why are they so happy." The space shuttle didn't just fly out of space and hasn't come back yet, so it's too early to be happy. ”

Li Hao said with emotion: "It's not early at all, they have a reason to be happy, they can send the space shuttle out of the earth safely, and this test flight is a perfect success."

My requirements for this test flight of the space shuttle are very low, that is, to send the space shuttle out of Earth safely. Verify that its engine and enclosure meet the design requirements.

Now the major powers of the world have only a 30% success rate in launching a new spacecraft for the first time. The success rate of the next few launches was only about 50%.

Industrial products have a gradual maturation process. No product is an exception.

Due to the different systems in Huaxia, the success rate of the launch is somewhat high. But it's not as high as people think.

We see highlights of the launch on TV or on the Internet.

This can no longer be said to be a space mission, but has risen to a political mission. It is an absolute overinvestment, and every detail is planned through a long arrangement. In order to ensure the smooth completion of the space mission.

Our shuttle as a new type of spacecraft. It can successfully ignite and fly outside the earth on the first test flight. This is extremely difficult. ”

After Zhou Yunsheng heard Li Hao's explanation, she nodded in understanding.

See the space shuttle soaring through space. Li Hao and the others sat on the chairs, sipping melon seeds and drinking juice and chatting.

Director Qiu Shi opened his mouth and asked, "Chairman Li, your space shuttle has flown off the earth smoothly. I'm here to wish you every success.

When a normal space mission arrives here, it enters the orbit predetermined by the spacecraft. It can run in orbit for a few days or as short as a few hours.

I see that when your shuttle was just out of space, its biggest engine started ignition. If you see the target orbit shown on the light curtain, it should be a geosynchronous orbit.

What does your space shuttle do when it goes into geosynchronous orbit? ”

After Qiu Shi finished speaking, he relaxed his mind and waited for Li Hao's answer like listening to a story.

And the secretary sitting next to Qiu Shi, he didn't seem to care. It's just that his eyes flickered, staring at Li Hao with the corner of his eye. Earnestly waiting for his answer.

"I don't know what the shuttle is going to do? Maybe the technology will be verified. Li Hao replied with a smile and waved his hand.

At the same time, he turned his head to look at Ma Yiming, who was staring at the big screen.

Ma Yiming sensed that Li Hao was looking at him, and responded: "The space shuttle is indeed flying to a geosynchronous orbit of more than 36,000 kilometers. His lord's mission is to go up and clean up space junk. ”

When he talks about the task of cleaning up space junk, everyone is thinking about space junk. None of them are new to the term.

Space junk is a useless man-made object that orbits the Earth.

Space junk can be made up of satellite debris, paint, dust, and entire spacecraft wreckage.

The electronic synthesized sound also rang in everyone's ears. By special means, the sound is confined to their area.

"Since the Soviet Union launched the first artificial satellite of mankind, Sputnik 1, countries around the world have carried out more than 4,000 launch missions, generating a large amount of space junk.

Although most of it burned up by falling into the atmosphere, more than 4,500 tons of space junk remained in orbit as of last year.

Space junk is generally in low-earth orbit at an altitude of 300-450 km, moving at a high speed of 7-8 km per second.

In geosynchronous orbit at an altitude of 36,000 km, it moves at a high speed of 3 kilometers per second.

Depending on the relative velocity at the time of the orbital inclination collision, space junk collides with other spacecraft and can produce relative velocities of more than 10 kilometers per second.

Because of the tremendous kinetic energy associated with the collision, the collision of space junk with other objects produces enormous destructive force.

As a result, a collision with a spacecraft such as a satellite, a manned spacecraft or the International Space Station can cause damage to machines and endanger the lives of astronauts.

It has been calculated that a piece of space junk with a diameter of 50 centimeters can destroy the shuttle.

If a space shuttle collides with a space shuttle, a few millimeters of space junk can cause damage to its internal structure and prevent it from continuing to work. ”

Director Qiu Shi said with a smile: "Chairman Li really has an international spirit, and he has spent so much energy to clean up the space junk that is extremely troublesome in the world. This is a very kind act. ”

"You might as well just say that I am the Holy Mother of the White Lotus. We, the capitalists, rarely have the time to help ourselves for free. It can't be helped. Li Hao said with a wry smile.

He couldn't admit it, and it wasn't for that purpose in the first place.

If he really sells his reputation, he agrees. Director Qiu Shi will definitely take the opportunity to propose a formula of shared strength-based enhancement liquid, so that this technology can serve more people.

He already knew a lot about the cheekiness of these people who climbed up the pole.

Li Hao briefly explained: "The mission of the space shuttle is to clean up space junk. It's not that we think so much, it's that we have to do it, we have no choice.

If there is a pile of garbage on the road in front of our house that can damage the vehicle, everyone else rides a bicycle once or twice a year. As long as he has enough skills, he can avoid hitting the garbage.

We drive in luxury cars, and we drive out almost every month. You say who will clean up the garbage in the end. ”

Everyone immediately understood what Li Hao meant, and now the mainstream countries are conducting space activities every long time. It is mainly the launch of satellites.

And the Space Exploration Group will definitely launch space shuttles frequently in the future. From the perspective of probability, it is also the probability that the Space Exploration Group will encounter space junk and have an accident.

The secretary sitting next to Qiu Shi suddenly said: "This space shuttle is too fast, and the propulsion of that large engine is also very powerful. It was only a few hours before it reached geosynchronous orbit from outer space. ”

I only saw a simulated animation of the space shuttle in space playing on the light screen.

There was a swarm of space junk moving at high speed towards the location of the shuttle.

I saw the space shuttle eject a pitch-black two-dimensional net from the cabin.

Ma Yiming explains: "This kind of net is made of a special two-dimensional film material, which is extremely tough and can withstand thousands of kilograms of pulling force.

Our goal is to wrap the space junk in this two-dimensional net, so that a lot of space junk can be gathered together.

Due to the gravitational pull of the earth, this garbage will gradually be pulled towards the earth. Finally burned up in the atmosphere.

The two-dimensional mesh has its own power, and its propellant is stored in liquid form in a gap of 10 microns wide between two membranes.

It can provide a weak power, which can make extremely complex movements in the vacuum environment of space.

A large two-dimensional net with a size of 100 square meters weighs about 0.5KG, which is very convenient for storage and use.

It can be clearly seen in the animation that the large net is ejected, and the thrusters immediately work according to the pre-programme.

Originally, a net was curled up, and the propellant was immediately activated, and the whole large net was stretched open and flew forward. It's like a spider's web ready to hunt.

Soon came to the edge of space junk, due to the impact. The two-dimensional net naturally closes to the rear around it. Soon wrapped up space junk.

When Ma Yiming saw this scene, he exhaled and said lightly: "Our design is really successful, and we can use it to efficiently clean up space junk."

A clean space environment is particularly conducive to the movement of our space shuttles between orbits or the placement of satellites in certain orbits. ”

They continued to visit the ground command center, and everyone was well worth the trip.

The shuttle, on the other hand, acted as a diligent cleaner. Cleaning up most of the space junk in Earth's orbit.
