• The heat shield is made of phenolic impregnated carbon ablator ( PICA ).
• After extensive study, NASA has selected the Avcoat ablator system for the Orion crew module.

• The ablator itself is a unique blend of g " ) of acceleration on the lander and rover.
• The report goes on to suggest that using a thicker ablator may improve performance, but this increases its inertia.
• The backshell and heat shield are made of the same materials, but the heat shield has a thicker,, layer of the ablator.
• The memo page 5 discusses the mix of ablator material and capsule fuel due likely to hydrodynamics instabilities in the outer surface of the ablator.

• NASA chief Sean O'Keefe confirmed Thursday that one theory being tested by NASA investigators is that air bubbles or ice formed under the silicone-based ablator, possibly causing insulation to break free.
• Given the ever-increasing demands for higher uniformity of the targets, this approach does not appear practical, as even the inner ablator and fuel itself currently costs several orders of magnitude more than this.
• The realization that the simple exploding pusher target designs and mere few kilojoule ( kJ ) laser irradiation intensities would never scale to high gain fusion yields led to the effort to increase laser energies to the 100 kJ level in the UV and to the production of advanced ablator and cryogenic DT ice target designs.
