Many lightweight thermal protection system (TPS) materials have a large degree of open porosity, which can make them highly permeable to gas flow. Recently, a permeability measurement apparatus was constructed to test rigid, porous TPS materials. This note presents further gas permeability, made with this apparatus, on two lightweight ceramic ablator materials; viz., phenolic impregnated carbon ablator and silicone impregnated reusable ceramic ablator
