What is does Ablation mean?

Ablation refers to the removal or destruction of material from the surface of an object, often through processes like melting, vaporization, or erosion. It is commonly used in medical contexts, such as the removal of tissue or in procedures like cardiac ablation to treat irregular heartbeats. In engineering and space applications, ablation describes the loss of material from a spacecraft's surface due to extreme heat during atmospheric re-entry. Overall, it involves the gradual or instantaneous removal of substance from a solid body.
