“While the Avcoat material is very similar to the one used in the Apollo missions, it has been reformulated slightly for #Artemis. This is partially due to having to re-engineer the technology, and partially to meet environmental legislation outlawing certain compounds. The other change is the way the Avcoat has been applied. In the #Apollo missions, one large piece of #Avcoat was used throughout the bottom of the spacecraft, but in the Artemis I and II missions, the heat shield is made up of more than 186 blocks or tiles.

It's got a major inherent problem … a structural problem, and they do not understand the #physics of that problem," — Dr Charlie Camarda, Astronaut (STS-114), NASA Thermal Structure Laboratory.

1960s Apollo era #Engineers & #Physicists are still peak rocket engineering.

For those of you who are wondering how the #Orion capsule was able to re-entry the #Earth atmosphere at a speed of almost 40000 km/h reaching 2700°C, here is the picture of the #Artemis #heat #shield. It is based of a material called #Avcoat, an improved version of what was used for the #Apollo missions.

During re-entry, avcoat ablates while transporting the heat away from the #Orion #spacecraft.
