PICA (Phenolic Impregnated Carbon Ablator) is a ablative thermal protection system by Fiber Materials Inc. / NASA Ames. Rated to 2,900°C. Status: Active.

PICA is a lightweight carbon ablator developed at NASA Ames Research Center that provides high-performance thermal protection at very low density. It was the primary heat shield material for the Stardust sample return capsule, which holds the record for the fastest reentry speed of any human-made object at 12.4 km/s. PICA served as the basis for SpaceX’s PICA-X.
