Can the ground destroy satellites in the sky?

Correct, China is using the same killer satellite as the Soviet Union back then, that is, hitting the satellite with a satellite, not hitting a satellite with a missile. The first thing that Americans thought of in the 60s was to hit satellites with missiles, but later they found out that it was not practical at all. The Soviets also abandoned this plan.

Later, the Americans successfully used F15 missiles to launch missiles at an altitude of 10,000 meters to destroy satellites in the 70s, and the Soviets later successfully carried out experiments on killer satellites, and after the American space shuttle went into space, the United States had an unprecedented advantage in this regard, although the later Star Wars program was canceled, but the Americans did not give up their efforts in this regard, including laser attacks on satellites. Since the missile defense system is progressing relatively well, the United States can also use this technology to attack satellites. So the conclusion is that with modern technology, launching a missile from the ground can completely destroy a satellite.

On January 11, 2007, China used an anti-satellite ASAT ballistic missile to successfully destroy an abandoned meteorological satellite, Fengyun-1C, located 859 kilometers above sea limits. The US Intelligence Agency announced that it was a KT-2 missile with a length of 6,500 meters and a range of 6,500 kilometers. The missile was launched from the Xichang Satellite Launch Center in Sichuan Province, and after going straight into the predetermined satellite orbit, it accurately hit a hexahedral meteorological satellite with a length of one meter.

Yes, that's for sure, you can control satellites from the ground, you can destroy satellites from the ground.

Yes, the Soviet Union developed anti-satellite satellites 30 years ago.

Yes. Our country is very strong in this regard.

The frog at the bottom of the well. The United States was able to fight in the 80s.

China is the second country in the world to hit a satellite with a missile. But more than 20 years later than in the United States.

Didn't we shoot down a scrapped satellite some time ago?

Satellites do not fall from the sky after launch.

According to the principle of physics, when an object moves in a circle, a centrifugal force is generated, and the magnitude of this centrifugal force is proportional to the square of the rotational speed. Therefore, the greater the speed, the stronger the centrifugal force, when the centrifugal force and gravity are balanced, the object can rotate around the earth non-stop, so the flight speed of the artificial satellite must be large enough to balance the gravitational force, so that it can fly without stopping. Among the commonly used satellite orbits, there is the so-called geosynchronous or sun-synchronous, which means that a certain parameter of the satellite orbit is the same as that of the earth or the sun.

If a satellite orbits the Earth as fast as the Earth's rotation, the satellite does not move from the ground, and this satellite orbit is called a geosynchronous orbit. If the orbital surface of a satellite changes as fast as the Earth's revolution, the angle between the orbital plane of the satellite and the Sun is approximately unchanged, and this kind of satellite orbit is called a sun-synchronous orbit. Therefore, the geosynchronous orbit is the satellite chasing the earth;The sun-synchronous orbit is not a satellite chasing the sun, but an orbital plane chasing the sun.

Communication satellites need satellites to chase the ground;Telemetry satellites require orbital planes to chase the sun, allowing the satellite to perform telemetry under the same sunlight. How do artificial satellites escape gravity and enter space orbit?In order for an artificial satellite to break away from gravity, it must use a rocket to fly into the sky at a speed of at least one kilometer per second, which is called the disengagement velocity.

After the rocket separates the satellite from the satellite at a considerable altitude, the satellite uses the fuel it carries to propel into its final orbit. The so-called precession refers to the phenomenon that the satellite departs from the earth's equator and follows a given orbit around the earth and returns to the equator without passing through the origin. Since the shape of the Earth is not an ideal spherical shape, satellites are affected by the oblate effect of the Earth, so the orbital plane is not fixed and precession occurs.

The satellite moves in a circle around the earth at a constant speed, generating centrifugal force, and when the centrifugal force is equal to the gravitational force of the earth, the satellite always moves in a circular motion in a certain orbit around the earth. If the inertial velocity of the satellite is greater than the gravitational binding force of the Earth, the satellite will overcome the gravitational pull of the Earth and fly into outer space.

China's development is very rapid, which is obvious to all at home and abroad, but there is still a certain gap with the world's first-class advanced level, which we must also recognize. However, foreign experts are also following the nonsensical hype, and some ** topics are really laughable.

According to this expert, a US research report entitled "Foreign Space Pre-War Good Capabilities" pointed out that China already has some kind of nuclear *** that has been detonated in outer space, so as to achieve the purpose of destroying or interfering with US satellites, and there are more than 500 US satellites at an altitude of more than 10,000 kilometers. China's increasingly powerful anti-satellite capabilities will facilitate China's so-called denial operations.

I don't know how powerful China is, but the ability of American experts to fool is ashamed of themselves, the slogan of the United States playing all over the world in an hour is still in my ears, dozens of naval bases around the world, countless large and small ** all over the world, but always fool him about the threat of the source country has a smart lead, which is really speechless.

Artificial Earth satellites orbit the Earth at a speed of kilometers and seconds. The motion of the satellite is equivalent to the motion of a flat-thrown object with an initial velocity of kilometers and seconds, that is, in one second, the satellite "horizontally" travels through kilometers parallel to the earth's surface, and at the same time "freely falls" meters according to the law of free fall motion. Due to the rotation of the Earth, the ground also "bends" meters in a second.

The satellite keeps falling down, the earth's surface keeps bending, and the satellite keeps a certain distance from the ground so that the satellite never falls to the ground. Such satellites are essentially "falling bodies", and the falling route is a circle. When the velocity of the satellite is greater than kilometers and seconds, the orbit is an ellipse, and the Earth is located on one of the focal points of the ellipse.

On the one hand, the satellite is affected by the gravitational pull of the earth, forcing it to fall to the earth; On the other hand, due to its certain velocity, there is a centrifugal effect that overcomes the gravitational pull of the earth. The effect of these two actions forces the satellite to fly elliptically around the Earth. The key here is speed.

The speed of the satellite is less than kilometers and seconds, and it falls; When the speed is equal to and greater than kilometers and seconds, it is free from the influence of the Earth and travels into space.

Satellite is a modern term that refers to a natural celestial body that orbits a planet and orbits periodically in a closed orbit, and an artificial satellite can also be called a satellite. An artificial satelliteAn unmanned spacecraft that orbits the Earth in orbit (at least once). Artificial satellites basically orbit the earth according to the laws of celestial mechanics, but the actual motion is very complicated due to the influence of the non-spherical earth's gravitational field, atmospheric drag, solar gravity, moon gravity and light pressure in different orbits.

Artificial satellites are the most numerous, most versatile, and fastest-growing spacecraft launched. The number of satellites launched accounts for more than 90 per cent of the total number of spacecraft launched.

The artificial satellite is mounted on the rocket, and the rocket is propelled to fly into the sky by the engine at the bottom of the rocket.

Because someone pressed the start button...

The premise of the normal operation of the satellite is naturally that it can be controlled and telemetric, that is, it must be controlled by the ground;

Satellites that are out-of-life or fail prematurely cannot be telemetrically controlled, but may be monitored by some terrestrial agencies, such as NASA, one of the purposes of which is to prevent obsolete satellites or debris from hitting other spacecraft.

If it's too small, there's probably no way. For example, India launched 103 satellites with one arrow some time ago. When these little things fail, they are space junk, which is equivalent to dangerous waste, and they can only wait for them to crash on their own under the resistance of the outer atmosphere.
