  1. Previous Missions

  2. Material Properties

  3. Design Factors • Heating Duration  10-20 minutes • Heat Soak • Increases Thickness of Ablator • Large Area  4x8m • Large Volume of TPS • Weight Limits

  4. Design Algorithm • Caclulate heating history for several points of aeroshell • Choose materials for each point • Size depth of TPS for each point • Calculate TPS Volume  Mass • Hand Mass over to Structures
