Space junk is moving at high speed on the Earth's surface. If there is a collision, it may cause certain damage to the satellites of mankind.
-
It will produce ** and thus affect the earth's air layer, which will cause unnecessary losses to people.
-
There is mainly the possibility of impacts on artificial satellites, probes, spacecraft, and future space stations, in which these objects travel very fast, and a small impact can cause great damage.
-
Space junk collides and may cause some impact on the surrounding planets.
-
Space junk collides, and it is easy to cause some junk to crash into the earth.
-
Because the physical parameters in space are different from those on Earth. Even a simple collision can be hazardous.
-
If space junk collides, it will have an impact on our artificial satellites.
-
The collision of space junk may also cause dangerous phenomena such as **.

It is inevitable that there will be some garbage in life. Due to the large population, people can produce a lot of garbage in a day, which can cause very serious damage. People think it's feasible to throw garbage into space because it's big enough to hold all the garbage that humans produce, but it's very harmful, even if we have the means to launch it out of the Earth's atmosphere.
It also has the potential to darken our skies and pollute our air, which can reach speeds of up to 30,000 kilometers per hour if it turns out to be old space junk. Even a small piece of trash can cause a lot of damage, and it comes at a cost. If you want to take a lot of garbage from the earth, it will be very expensive.
This cost is very unbearable for people, and it is also necessary to take into account the mass of the earth and to know that waste is actually a product of the material cycle.
If they are thrown into space, the mass of the Earth decreases over time, which eventually leads to a change in the Earth's orbit, but it is also possible to send a small amount of garbage to the Sun. This method is less risky, as this garbage does not cause harm to our planet after being incinerated by the sun to produce toxins, but still pollutes space. Since the sun is so far away from the earth, we need to do a lot of calculations, and we need to take into account the fact that all this garbage will return to the earth.
As time moves, some of the junk that is sent into space, may fall, so it will return to the atmosphere, and when it burns in the atmosphere, it will pose a great threat to the environment. With these examples, we can see that throwing garbage into space is not feasible. This method can cause very serious harm and requires a lot of wasted costs.
Although this way is not feasible, we can still think of some other better ways to dispose of waste, for some of the more polluting materials. We can also find some alternative materials, and we can also ** some garbage. I believe that with the development of time, we can also find more suitable waste disposal methods.

This junk will float in space and then operate according to the gravitational pull of space, and at the same time will occupy the best orbit above the Earth, and eventually become the killer of satellites.
-
This will cause a lot of pollution, and it will also cause a lot of waste, and it will accumulate a lot of garbage in space.
-
If you throw garbage into space, there will be a lot of garbage in space, which will also pollute the environment and affect the ecological environment of the earth.

The reason why space junk poses a hidden danger is that space junk travels at orbital speed and has huge kinetic energy (more than 7km s), and if it collides with them, it may seriously damage the operating spacecraft and even threaten the life safety of astronauts when they are outside the capsule.
Space junk refers to various man-made waste bodies and their derivatives in space. These objects range from the burning residue of solid-state rockets to the presence of multi-section rockets that are abandoned after launch.
Space junk not only brings huge hidden dangers to the aerospace industry, but also pollutes the universe and brings disasters to mankind.
There are only three ways to generate space junk: first, spacecraft debris produced intentionally or unintentionally. The second is the careless negligence of astronauts. The third is the wreckage of satellites and rockets.

As humanity expands its horizons beyond Earth and begins to consider space missions of extended duration, sustainability requires launching more spacecraft that increase the risk of collisions with existing space debris and space junk. One way to remove these pieces of wreckage is to tow them to a safe area with a "trailer tow". In a new study** published in the European Journal of Physics, scientists from the State University of Ferra de Santana, Bahia, Brazil, simulated the complex rendezvous action of "trailer towing" to clean up space debris.
to reduce the risk of collisions, which can cause irreparable damage at the moment of coupling. As the study authors point out, the space mission takes place in an environment of about 3,600 artificial satellites, of which less than a third are in operation. Non-operational units are susceptible to leaks, ** and fragmentation, further scattered around the Earth – especially in low Earth orbit (LEO).
This makes towing operations to clean up these wreckage desirable, but also dangerous. The use of propulsion systems to control the relative velocity and position of objects during rendezvous maneuvers around the Earth was studied. This operation requires zero speed and relative position of towed and fragments at the moment of connection.
De Jesse and Santos examined these operating parameters by solving the multivariable tensor equation and found that the encounter maneuver of the space debris towing vehicle could be carried out in the shortest possible time, and that synchronization was created by simultaneously zeroing the velocity and relative final position of the two objects.
Of course, successful connections between space objects can be applied to more situations than just the movement of space debris. Connected vehicles could be an important part of the development of sustainable long-term space missions. Spacecraft are prone to collisions with space debris, and as launch rates continue to grow, so does the likelihood of catastrophic accidents.
Mitigation measures include sending trailers in an attempt to capture debris and bring it to the area of atmospheric towing activity. Rendezvous maneuvers need to be operated safely, taking into account the risk of collisions at the moment of coupling between vehicles, in the operation of SpaceClean, and in other operations.
The perfect rendezvous is done with zero relative velocity and position shield resistance, but this condition needs to be achieved with sufficient technical precision. In this study, by solving a multivariate equation, the conditions for simultaneous and minimum time intersection maneuvers and the propulsion technical parameters were found.

Space junk generally moves at a speed of 7-8 kilometers per second in low-earth orbit at an altitude of 300-450 km, and at a speed of 3 kilometers per second in geostationary orbit at an altitude of 36,000 km, and the relative velocity at the time of collision can even reach more than 10 kilometers per second according to the inclination angle of the orbit, so it has huge destructive power.
Therefore, if space junk collides with an operating satellite, manned spacecraft or the International Space Station, it can endanger equipment and even the lives of astronauts, and it is calculated that a single piece of space junk with a diameter of 10 centimeters can completely destroy a spacecraft, and a few millimeters of space junk can make it impossible for them to continue working. As a result, space junk has become an international problem.

In the history of astronautics, space junk has caused a number of accidents. Although the consequences are not serious, they have attracted great attention.
In 1983, the space shuttle Challenger collided with a millimeter-diameter piece of paint shards, causing a scratch on the porthole and forcing it to return to Earth early. In 1986, shortly after the European Space Agency's Ariane rocket entered orbit, 564 pieces of wreckage about 10 centimeters in size and 2,300 pieces of small fragments were formed. This garbage later directly caused the failure of two Japanese communication satellites.
On September 15, 1991, the distance between the U.S. space shuttle Discovery and the wreckage of a Soviet rocket was only a kilometer. To avoid a possible collision, the ground command system warned the shuttle to distance itself from the wreckage.
Space junk travels at a speed of 6 to 7 km/s in space, and spacecraft are also moving at high speeds, with relative velocities of up to 10 km/s. Therefore, a small piece of space junk is enough to cause huge damage to an artificial satellite or manned spacecraft. A 10-gram piece of space junk collides with an artificial satellite, and the satellite is punctured or destroyed in an instant.
If it hits a manned spacecraft, the consequences are even more unimaginable.
