Plural form; the processes or instances of removing or vaporizing material from a surface, especially through heat.
From 'ablation' (noun form of 'ablate'), derived from Latin 'ablatio.' The suffix '-ation' denotes the action or result.
Medical ablation is fascinating too—doctors use it to burn away abnormal heart tissue or tumors, so 'ablate' is just as important in hospitals as it is in spacecraft design.
