NASA Confirms Orion Heat Shield Performs as Expected on Artemis II

NASA’s post‑mission analysis of the Orion spacecraft’s heat shield from Artemis II confirms the system met all performance expectations. Four astronauts rode the spacecraft around the Moon, reaching 39 Mach and enduring peak temperatures over 4,000 °F while the cabin stayed in the mid‑70 °F range. The heat shield, made of 186 Avcoat blocks, suffered only nine spots of char loss—ten times fewer than the 103 spots seen on Artemis I—thanks to a trajectory change that shortened the downrange distance during reentry. Divers captured underwater imagery of the shield after splashdown, and subsequent x‑ray scans at Marshall Space Flight Center are refining material models. The data will inform upgrades for Artemis III, ensuring uniform Avcoat performance and bolstering crew safety for future lunar landings.
