Ablator is a resource that is a vital component of most heat shields. During atmospheric entry, ablator will slowly be consumed, dissipating heat in the process. Ablator can not be replenished or transferred between parts. If a heat shield runs out of ablator it will stop preventing overheating for shielded parts. Ablation shields work by allowing the material to burn away to dissipate heat. The exception to this is the Heat Shield (10m), which relies on drag to slow it down before overheating. As of version 1.2.2, an overheating bar shows up on ablative heat shields. This bar never reaches the point of explosion reentering at "sane" speeds, but will do so when ablator runs out or the entry is too fast or long. Ablator is consumed when closer than 2,500 Megameters from kerbol.
