Photos: NASA's Orion Spacecraft Heat Shield on Display

Each Avcoat-filled cell in the heat shield’s honeycomb structure is inspected by a robotic X-ray scanner. Once the Avcoat application is complete, the heat shield will be machined, sealed, primed, and finally painted before it is shipped to NASA’s Kennedy Space Center in Florida for installation on the Orion crew module.

Textron engineer Anthony Cudia demonstrates the caulk-gun-like tool that is used to inject Avcoat into the honeycomb cells. Cudia originally helped develop the gun for NASA’s Apollo program.

The fiberglass honeycomb is bonded to the heat shield and provides structural reinforcement to the ablative Avcoat material so it doesn’t crack. Engineers have designed the heat shield to withstand extreme temperatures during re-entry as well as the impact of ocean splashdown.
