Abstract

A thermal protection system including a plurality of layers. A first layer includes a passive insulation material. A second layer includes a phase change insulation material. A third layer is positioned between the first layer and the second layer to separate the passive insulation material from the phase change insulation material. A structural system extends through the first layer, the second layer, the third layer, or a combination thereof.
