Some people are worried that the spacecraft will be shattered by cosmic debris in the future, how to

This kind of thing is a very small probability, because the spaceship itself has a certain probe in front of it, and if there is debris, it can be advanced ** and will be dodged in time, so this situation is no problem at all.

Although the universe is a vacuum and cannot use sound waves, it is possible to detect cosmic debris in advance with electromagnetic waves, and to avoid debris by changing direction with thrusters.

Spaceflight should divide the flight trajectory, and when dividing the orbit, the orbit should be cleared, just like the road on which our car drives, and in addition, the space flight can also attach an energy field to avoid the impact of objects.

Wireless positioning technology can be used to locate cosmic debris in advance to prevent the spacecraft from being shattered by cosmic debris from outer space.

Cosmic debris is nothing more than some space junk and some small planetary spheres, whether it can crash into a spaceship, it is estimated that it is about the same, just like a bird hitting a flying plane, this should not be difficult immediately!

No. Because the spacecraft is controlled by astronauts, the spacecraft will avoid the impact of cosmic debris.

There are no cosmic fragments. For the earth, due to the abandonment of a large number of human aircraft, satellites and spacecraft, they remain in space and become space junk. Further beyond the Earth, there are mainly meteors and comets.

Space junk is flying in space at very high speeds. In the event of a collision with a spaceship, damage to the spacecraft is a certainty. It's just that it hasn't reached that serious yet.

Cosmic debris is the debris of abandoned satellites and spacecraft, because of the rotation of the earth, their speed will be faster than the speed of bullets, and they can crash into spaceships.

The spaceship flies fast and hits anything.

Cosmic debris refers to space junk, or fragmented celestial debris is some large rock. It's that it can crash into the spaceship, it's that it's too fast, it's powerful, and it's destructive.

The required mass multiplied by velocity is equal to kinetic energy: ek = (1 2) mv 2.

Yes, depending on his quality and speed.

Why remove space junk? It must be because of the space junk that there must be harassing the spaceship.

Cosmic debris mainly refers to the debris of some celestial bodies or cosmic dust. Of course, some tiny objects and many man-made objects (the wreckage of satellites and rocket boosters) can also be counted. Due to the influence of the gravitational pull of various large celestial bodies in space, these debris are often in high-speed motion, at least reaching the first cosmic velocity (kilometers per second), such a high speed, its kinetic energy is also huge, if it is equipped with the spacecraft, because the speed of the spacecraft is also very fast, their relative speed is as high as more than 15 kilometers per second, which is equivalent to two missiles colliding, which will be damaged.

If you don't clean it up, a lot of metal fragments will fly in space...

A lot of metal fragments fly in space, and in some special cases, these space junks may fall back to Earth.

Because it has the potential to cause harm to the planet!! In some special cases, there is a possibility that this space junk will fall back to Earth.

Because there are a lot of risks associated with space junk.

Because garbage is a more laborious and laborious thing.

Because space junk is costly.

Because there is no one to manage, the cost is also high.

Because it has the potential to cause harm to the planet!!

But even if one of the relay antennas is damaged, don't worry.

In some special cases, there is a possibility that this space junk will fall back to Earth.

Judging from the current scientific and technological means, if a spaceship is created, then even if the technology has reached the speed of the spaceship is very fast, it is indeed possible that there will be debris that hits the space and burns it, because our human technology has not yet reached the level of making a spaceship very strong, so when we humans really want to study spaceships, then a problem that must be overcome is to find a very hard materialThis material must be hard enough to resist the cosmic debris of space, only after breaking through this technical problem, we human beings can freely sail in space, of course, in addition to breaking through this technology, human beings may also be able to solve this problem with the following technologies:

1. Electromagnetic defense system

I believe you may have seen some science fiction films in the spacecraft will have some electromagnetic defense system, we figuratively call it a defensive cover, in fact, from a scientific point of view, this electromagnetic defense system is possible, and the defense capability will be quite strong, so if we humans can skillfully use this defense system, it is also possible to solve this problem.

2. Laser**

We all know that the speed of laser ** is quite fast, if the scientific and technological level of human beings on the laser ** has a breakthrough, then it is very likely to be applied to the defense of spaceships in the future, so it is very easy to smash some meteorites and other space debris, so this ** may also be the key to solving this problem.

3. Active dodge system

If it is a small and medium-sized spaceship, then when the level of human science and technology reaches a certain level, the detection of radar performance must be very powerful, so when the radar detects cosmic debris in front of it, it is likely to activate its own active evasion system, as long as conditions permit, the evasion speed of the spacecraft may also be quite fast.

Not necessarily, it should have some impact.
