Zhang Zhi heard someone saying that something was blocking the return of the space shuttle to Earth.

He looked up and saw a light curtain on the walls of the dining room, where the shuttle was on its way back to Earth.

The quantum radar on the space base ship and the space shuttle, both found something ahead, approaching the space shuttle at high speed.

Zhang Zhi's heart suddenly became nervous, his first thought was missiles, and then he thought that it was impossible, and now the space shuttle is in a low-earth orbit of 450 kilometers.

At present, the missiles of various countries cannot reach this height. Don't look at the range of strategic missiles that are tens of thousands of kilometers, their altitude is just out of the atmosphere.

At this altitude, Earth's weapons could not attack the shuttle.

Zhang Zhi called up the data map of the quantum radar and showed it in front of him with the light curtain of the quantum mobile phone.

He noticed CCTV reporters resting in the rear. Seeing them discuss, I picked up the quantum phone and scared all this.

He smiled, what he could show publicly. None of them need to be kept secret.

Zhang Zhi looked carefully at the data map of the radar, which showed that the blocked object had no energy reaction.

That said, it is not an active weapon such as a rocket.

Poplov looked at it carefully a few times, and his expression relaxed.

He glanced around a few times and said, "Mr. Zhang, Director Bai." I think I know what's in the way. ”

Bai Qing said in surprise: "What is this, it won't be a satellite of other countries in orbit." We will work with all countries. They will inform each other of the trajectories of their respective satellites.

As you know, under normal circumstances, satellites that suddenly change their orbits will not be encountered. Unless encountering military reconnaissance satellites.

Now that the world is generally peaceful, there are no hot spots in the skies over Asia. Such satellites rarely come. ”

Poplov shook his head and said: "This is not an artificial satellite controlled by people, and the path we returned to was carefully chosen, avoiding many problems.

The object in front of it should be space junk, information sent from quantum radar, which takes on irregular patterns.

Unlike satellites that can be controlled by humans, especially since its density varies too much. The ingredient distribution is very unreasonable.

It can be inferred in many ways that it is space junk. ”

Zhang Zhi looked at Poplov and nodded with satisfaction.

He has a specialization in the art industry, and he can't tell what it is from the complex quantum radar data map. Poplov could easily see it.

Bai Qing heard that it was space junk, and a solemn look appeared on his face.

He said solemnly: "If this is space junk, it will not be easy to handle." If it is a controlled spacecraft. In this case, both parties will try to avoid it.

This situation will not cause an accident, in fact, this situation is best handled.

Space junk is not under anyone's control, and it is the most dangerous in space.

When spacecraft and satellites happen, we avoid them.

This is the area of low earth orbit, officially the highest concentration of space junk, and their speeds reach up to 8 kilometers per second.

As long as it is 10 centimeters in size, a spacecraft or satellite can be scrapped.

It would be a shame that I suggest that your shuttle immediately change its orbit and collide with this garbage. ”

Zhang Zhi smiled when he heard that it was space junk.

He glanced at Bai Qing, and then at the people who were actively discussing in the restaurant.

He waved his hand and said, "Let's follow the same path." If the orbit of the shuttle were to be changed, we would again find the right time to return to Earth.

It can be as short as a few hours, or as long as a few days. Or somewhere else.

It's live now, and we've posted all the time of the landing.

The whole country is watching, and the temporary changes are not good. ”

Zhang Zhi saw Bai Qing's appearance of wanting to speak and stopped, and said very confidently:

"Director Bai, don't worry. Our space shuttle, as long as it is not a large space junk of more than five meters, will not be damaged.

When we designed the space shuttle, we took into account the impact of space junk, and the space shuttle has the means to deal with space junk. ”

Hearing Zhang Zhi say this, Bai Qing's expression relaxed, and Li Lingqiu also let go, and she lifted her heart.

They relaxed down, and in the virtual world, the discussion among netizens was very lively.

"I'm really worried about the space shuttle, and everything started well. On the way back, the radar detected a shadowy area moving at high speed.

I don't know what is standing in the way ahead, and whether the shuttle will be able to pass smoothly. ”

There are two moons in the sky: "This still needs to be guessed, it must be an advanced weapon of the United States, and the space shuttle may be shot down."

The United States is 100 years ahead of other countries in the world, and the United States is the only country in the world that has the strength to deploy space weapons.

Crafting the 'Scepter of God' weapon from tungsten alloy metal rods, a high-energy laser weapon deployed in space. ”

Muyang Dog Butcher: "Silly roe deer, licking and kneeling your beautiful father's posture is wrong, this is the content in the movie."

Let's just say that the bluffing staff of God, tungsten alloy is hard and can withstand the burning of the atmosphere, but unfortunately it is useless.

On land, the thickness of the earth's crust is more than 30 kilometers. The power of tungsten alloy is limited, and if it is too fine, it will make a deep pit in the ground at most. It's too rough to ship.

It can't cause too much harm, and it is nonsense to say that it can destroy a city. Where does the energy come from.

I think the antimatter rod is about the same, and tungsten is impossible.

As for space laser weapons, the current technology can be realized, but only a little. How to solve the problem of energy supply. ”

Kang Ping {Aerospace Science and Technology Group Engineer}: "Don't argue, what is in the way, I have already found out what is."

You look at the image released by the reporter and the leaders of Xingyu Technology discussing in the restaurant. Data graph in front of Zhang Zhi.

The data on this is clear, and after a simple analysis, it is a large mass of garbage made up of space junk. ”

Not a schoolboy: "What is space junk and can it endanger the safety of the space shuttle?"

Teaching and raising bear children: "When the time comes for popular science, I will tell you about space junk, and people are too lazy to search."

Space junk, as it is officially called, is orbital debris, and its composition is complex.

Mainly, man-made objects in space other than working spacecraft.

Including debris generated by launch vehicles and spacecraft during launch, scrapped satellites, peeling off of spacecraft surface materials, and paint plaques that fall off from the aging of surface coatings.

Solid and liquid materials leaked from spacecraft. Debris from explosions and collisions of rockets and spacecraft. ”

Kangping: "Some people are very accurate in popularizing science. Space junk is dangerous, and most of it is waste from our space activities.

I guess the shuttle will have to avoid them, I don't know why it hasn't switched orbits yet. ”

The image on the light curtain of the space base ship changed, and the space shuttle was already very close to the space junk.

It turns on the high-intensity spotlight on the nose, and the front is clearly illuminated in an instant. It was captured by a camera on its fuselage and sent back to the ground.

Mom sells batches

Zhang Zhi looked at the picture taken by the space shuttle and scolded in his heart.

On the image, after the space shuttle took the shot, the star blue has been automatically labeled.

This space junk is more than 10 meters long and moving at a high speed of more than 8 kilometers per second.

There is still a word "nasa" left on it, Zhang Zhi searched for it.

It is a replacement of the space station, discarding the old space station parts.
