Ablative vs Non-Ablative Heat Shield

Compare an ablative heat shield (Apollo/Orion-style, chars and erodes to carry heat away) against a non-ablative reusable ceramic tile shield (Shuttle-style, radiates heat back out) during hypersonic atmospheric re-entry.

Toggle between an ablative heat shield and a reusable ceramic tile shield, drive the re-entry heat rate up manually or with the auto profile, and watch how each material handles the same plasma shock layer — one sacrifices itself to keep the structure cool, the other radiates heat away until pushed past its rated envelope or breached by a crack.

⚙ Under the hood

Compare an ablative heat shield (Apollo/Orion-style, chars and erodes to carry heat away) against a reusable ceramic tile shield (Shuttle-style, radiates heat back out) as a spacecraft re-enters the atmosphere. Drive the heat rate manually or with an auto re-entry profile, switch shield type, and crack a tile to see why any breach is catastrophic without a sacrificial material.
