Where Did the Launched Space Rockets Go
With the progress of science and technology, human beings have achieved remarkable results in exploring the vast universe. The launch of various space rockets is an important link in the development of space exploration. However, after the rockets are launched into the sky, where do they go? This is a question that many people are curious about.
Firstly, it should be understood that the distance from Earth to outer space is very far. Even if the rockets are launched at high speeds, it takes a period of time to get out of the Earth's gravity and enter into space. The speed required to escape the Earth's gravitational pull is about 40,000 km/h, and only when this speed is achieved can the rocket break through the Earth's atmosphere and enter into space. Therefore, at the beginning, rockets need to use a lot of energy to rise up. In the process of rising, they need to overcome gravitational resistance and air resistance. As a result, most rockets consume a lot of fuel during takeoff and quickly fly out of the Earth's atmosphere.
After the rockets leave the Earth's atmosphere, they enter into the space. However, they will continue to travel due to the inertia in a straight line. If there is no intervention, they will continue indefinitely in the universe without stopping. Therefore, in order to reach the designated location, rockets need to change their direction and velocity through complicated orbits. After the task is completed, the rockets are usually discarded in space and become space debris.
At present, there are thousands of pieces of space debris orbiting the Earth. These include dead satellites, discarded upper stages, and pieces of debris generated by collisions between objects. Space debris is harmful to space missions because they move at high speeds and can cause serious damage to satellites or other spacecraft. Therefore, countries around the world have proposed various solutions to space debris problems, such as space debris removal missions, space debris tracking systems, and laws and regulations to prevent future space debris.
In summary, the launched space rockets usually head for the designated location under complicated orbits after leaving the Earth's atmosphere. After the task is completed, most rockets become space debris unless the space agency carries out corresponding space debris removal missions. Therefore, while we are amazed by the magnificent take-off scenes of rockets, we should pay more attention to the safe and sustainable development of space exploration.
