NASA Reveals Why Orion’s Heat Shield Cracked Under Pressure

NASA’s investigation into the Artemis I Orion spacecraft’s heat shield issue revealed that trapped gases within the Avcoat material led to pressure buildup and char loss during reentry. Extensive testing, both pre-flight and post-flight, and simulation at NASA facilities have helped refine the heat shield’s design to prevent future issues, ensuring crew safety for subsequent [...]
