What is the strategy for the collision of US and Russian satellites, and how did they collide?

I don't understand strategy.

However, it is said that the collision was due to a miscalculation of the orbit of the American satellite, so the Russian satellite was knocked down.

At present, there are hundreds of satellites in the earth's orbit in various countries around the world, but compared with the vast space field, the probability of a satellite collision accident is still very low, unless there is a technical failure or other reasons to cause a collision accident. All in all, satellites provide services to human beings, and of course, human beings also need to respond to corresponding risks.

No, because each satellite has its own trajectory, and they will move according to their own trajectory, so they will not collide.

When launching a satellite, it is basically registered, and the orbit is calculated, and there is basically no collision.

I won't want to bump into it. Each satellite has its own specific orbit, plays a different role, and is planned and arranged.

With the rapid development of science and technology and the continuous exploration of space, we launch many satellites into space every year. With so many satellites converging on the Earth's periphery, will they collide?

At 11:55 a.m. EST on February 10, 2009, Iridium-33 collided with Russia's defunct Cosmos-2251 satellite over Siberia, the first satellite collision accident in history.

Space Satellites Play "Dodgeball" The floating debris left behind by the collision of two satellites of the United States and Russia will take several months to fix its position, which will affect the future space operations of the United States. Marine Corps General Cartwright attended a seminar on 13 July, in which he analyzed the collision incident between US and Russian satellites that occurred on 11 July. He stressed that the number of satellites is increasing, the orbit in space is crowded, and it is no longer possible to check the operation of satellites every few weeks as in the past, and countries should share complete information on the situation in space.

Satellite debris could be floating around the Earth's periphery for more than a year, "I'm afraid we're going to have to play dodgeball for a while." The two colliding satellites are in orbits higher up around the Earth, so the debris will stay longer, taking a month or two, and the U.S. military will not be able to track and locate these areas until all the debris and debris are secured. Countries will also be able to draw new orbital navigation routes.

Hazardous satellites collided and crashed into thousands of space debris.

Probably distributed in space at altitudes from 500 km to 1300 km.

According to Xinhua News Agency, US experts estimate that the collision of satellites will produce at least thousands of space debris.

According to the United States**12**, NASA has monitored dozens of large debris produced after the satellite collision. The debris has split into two clouds of debris.

Mattnet, a space junk research expert at NASA's Johnson Space Center, said that it is not yet possible to know how much debris will be produced by the satellite collision, because some of the debris may be only centimeters or even micrometers in size, which is difficult to detect for a while. He estimates that NASA will find at least a few thousand pieces of debris.

We know that this is going to happen sooner or later," Mattnay said, "and the problem of satellite collisions in space will become more and more prominent in the coming decades." ”

Yakushin, first deputy commander of the Russian Cosmonautics, said on the 12th that the Russian Cosmonautical Forces space control system is currently closely tracking the debris generated after the collision of Russian and American satellites, which may be distributed in space at altitudes ranging from 500 kilometers to 1,300 kilometers.

Because the relative velocity between space debris and the spacecraft is large, typically a few kilometres to tens of thousands of metres per second, even a slight collision between the two can cause significant damage to the spacecraft. A piece of wreckage the size of an aspirin pill can cripple a satellite.

At present, the United States Strategic Command has discovered and tracked 180,000 man-made space objects at this stage, including active and end-of-life satellites, rocket booster wreckage and space debris more than 10 centimeters in diameter.
