 (ă-blā′shən)
n.
1. Surgical excision or amputation of a body part or tissue.
2. The erosive processes by which a glacier is reduced.
3. Aerospace
a. The dissipation of heat generated by atmospheric friction, especially in the atmospheric reentry of a spacecraft or missile, by means of a melting heat shield.
b. The reduction or removal of heat-protective surface material by aerodynamic friction, as from a heat shield.

[Late Latin ablātiō, ablātiōn-, from Latin ablātus, past participle of auferre, to carry away : ab-, away; see ab-1 + lātus, carried; see telə- in Indo-European roots.]

ab·la·tion

(ă-blā′shən)
1. The wearing away or destruction of the outer or forward surface of an object, such as a meteorite or a spacecraft, as it moves very rapidly through the atmosphere. The friction of the air striking the object heats and often melts or burns its outer layers.
2. The process by which snow and ice are removed from a glacier or other mass of ice. Ablation typically occurs through melting, sublimation, or wind erosion.
