• Ablation of Pica-Like Material: Surface or Volume Phenomenon? 

      Lachaud, Jean; Mansour, Nagi Nicolas (Georgia Institute of Technology, 2008-06-26)
      The ablation of the char layer in ablative material is usually described in term of recession velocity of the overall surface. This description is valid for dense materials. However, the recession of the average surface ...
    • Arc-Jet Simulations of Ablators for the Mars Science Laboratory Program 

      Tang, Chun; White, Todd Richard (Georgia Institute of Technology, 2008-06-25)
      The NASA Ames team working with the Mars Science Laboratory (MSL) project has recently been involved in arc-jet tests to characterize the material response of candidate ablators to the high heat flux and high shear stress ...
