Will artificial satellites change the way people live or become space junk?

Through science and technology, we have made the people of this world "neighborhoods". Now, through our moral character and ethical commitment, we must make the people of this world "brothers." We must learn to live together as brothers and sisters – or we will all die together like fools.

To commemorate this presentation, let's now talk about what makes this world a "neighborhood" – it's something we rely on when we drive to a new location, when news comes from around the world, and even when the weather. That's right, I mean satellites! How far away are these satellites from Earth?

What happens when they stop working? How much other space junk actually exists there? And what are they doing?

By definition, a satellite can be any object in orbit around a planet. The Moon is Earth's only natural satellite, and it is about 240,000 miles (or 380,000 kilometers) from Earth. In addition to this, the satellites in orbit around the earth are all artificial satellites, or have been placed there by humans.

Satellites remain in orbit around the Earth thanks to the perfect balance between their speed and the gravitational pull that pulls them in the direction of the Earth. If the satellite accelerates, its centrifugal force will eventually be greater than its gravitational pull, causing it to fly into distant space. Conversely, if it is too slow, gravity will cause them to return to Earth.

All artificial satellites will eventually return to Earth if they are unable to continue to accelerate due to planned or unexpected mechanical failures. However, we don't have to worry that as these objects fall back to Earth, they will burn up before they can rub against the Earth's atmosphere. A satellite in low orbit can live up to 100 years, and a satellite in high orbit can live up to 1 million years.

In 2009, a U.S. Iridium communications satellite used for satellites** collided with a Russian satellite, resulting in thousands of separate pieces of space debris added to orbit. We need to work to clean up space to prevent this space debris from endangering the working satellites we rely on and future manned space missions.

Both of these are possible, but there should be more of a bright side.

But there should be more of the bright side.

The main thing is to change the way of life of human beings, but it has become space junk if it is not.

Artificial satellites will also become space junk, which is very difficult.

Sputnik still has more advantages than disadvantages, and it has changed the way people live.

Changing the way of life of human beings has brought a lot of convenience to human beings.

At this stage, it has changed human life.

It has not only changed the way of life of human beings, but also become the garbage of space.

But if you don't, you become space junk.

After changing human life, it became space junk.

In addition to artificial satellites, there are many high-tech equipment and technologies in space, including:

Space Station:The space station is a large-scale space facility established by mankind in space for scientific research, technology development and astronauts' livelihood support. There are two that are still in space, the International Space Station and China's Tiangong-1 space station.

Orbiter:An orbiter is a space spacecraft capable of long-term flight in Earth orbit for scientific research, Earth observation, and communications.

Space Telescope:A space telescope is a telescope that can observe the universe in space, and its observation effect is more accurate because there is no interference from the atmosphere. For example, the famous Hubble Space Telescope has discovered exoplanets, observed black holes, and photographed beautiful nebulae**.

Space Probe:A space probe is a spacecraft that is capable of probing and research in space to detect celestial bodies such as planets, comets, stars, etc. For example, the United States' "Curiosity" Mars rover, China's "Tianwen-1" probe and the "Zhurong" Mars rover with a wide bridge on the empty load.

It's the jujube that exists, and it's all related, because human beings launch too many objects into space, such as probe stools and spacecraft, as well as artificial satellites, all of which are gathered in near-earth orbits, so the scrapped ones have become space junk.

Yes, there is garbage, which has something to do with the launch of satellites by humans, after all, most of the garbage is garbage formed after the satellite fails.

According to common sense, there should be something, but it is certainly not garbage in the sense of the conventional meaning book, that is, the useless substances produced by planets or stars are easily classified as garbage by the state, and artificial satellites that are not used by humans are also space junk.
