Re-creating NASA’s Heat Shield Problem
Following the discovery of significant damage to the Orion capsule's heat shield during the Artemis I mission, a creator attempted to replicate the failure in a DIY setting. The experiment involved constructing segmented heat shield samples using NASA-published materials and subjecting them to propane torch heat to simulate re-entry conditions. The results confirmed that gas buildup from sustained pyrolysis was the primary cause of the material fracturing, aligning with NASA's official findings.
- ▪Massive chunks of the Orion capsule's heat shield were found missing after the Artemis I lunar mission, posing risks to future flights.
- ▪A creator recreated the heat shield using segmented structures and NASA-specified filler materials to test its durability.
- ▪The samples were cured with thermocouples and exposed to propane torch heat to simulate various re-entry patterns.
- ▪The experiment demonstrated that gas buildup from sustained pyrolysis caused the material to fracture, matching NASA's conclusions.
- ▪Despite some experimental flaws involving residual heat from the copper structure, the setup proved effective for testing ablative heat shields in a lab environment.

Re-creating NASA’s Heat Shield Problem No comments by: Maya Posch September 13, 2026 Title: Copy Short Link: Copy After the Orion capsule of the Artemis I lunar mission returned to Earth, it was found that massive chunks of its heatshield had been ripped off, posing a serious risk to any future missions. In a recent video in which [polymatt] takes a break from repairing old laptop shells and the like, he tries to recreate the Orion’s heatshield using a variety of methods and materials. For this test a number of samples were created, each using the same kind of segmented structure as the larger Orion heatshield. The filler was created from the published materials for the heat shield by NASA, requiring just serious mixing.
