Why does a satellite burns if it falls from orbit to atmosphere? BUT not when it is launched ffrom surface to orbit, ALTHOGH they pass through the same atmosphere
Going up, it does not reach a very high velocity until well out of the atmosphere.Himal kharel said:Why does a satellite burns if it falls from orbit to atmosphere? BUT not when it is launched ffrom surface to orbit, ALTHOGH they pass through the same atmosphere
Satellite burning refers to the process of intentionally destroying a satellite by burning it up in the Earth's atmosphere. This is done to prevent the satellite from becoming space debris and potentially colliding with other objects in orbit. Satellite burning occurs when a satellite's orbit decays due to atmospheric drag, causing it to enter the Earth's atmosphere and burn up.
Satellite burning and satellite re-entry are similar processes, but with different intentions. Satellite re-entry is a controlled maneuver where a satellite is intentionally brought back to Earth to be reused or disposed of in a controlled manner. In contrast, satellite burning is an uncontrolled process where a satellite's orbit naturally decays and it enters the Earth's atmosphere to be destroyed.
Several factors can contribute to satellite burning, including the satellite's altitude, the Earth's atmosphere, and the satellite's design and materials. Satellites in low Earth orbit (LEO) are more likely to experience atmospheric drag, leading to satellite burning. Additionally, the composition and density of the atmosphere can also play a role in how quickly a satellite's orbit decays. Finally, the design and materials of a satellite can affect its resistance to atmospheric drag and how quickly it burns up in the atmosphere.
Scientists use a combination of ground-based and space-based tracking systems to monitor satellites and predict when they will enter the Earth's atmosphere. These systems track a satellite's position, altitude, and velocity to determine its orbit and any changes in its trajectory. Scientists also use computer models to simulate the effects of atmospheric drag on a satellite's orbit and predict when it will re-enter the atmosphere.
The main risk of satellite burning is the potential for debris to fall to Earth and potentially cause damage or harm. While most satellites are designed to burn up completely in the atmosphere, there is still a small risk that some debris may survive and fall to the ground. Additionally, satellite burning can also contribute to the buildup of space debris in Earth's orbit, which can pose a threat to other satellites and spacecraft.
