NASA's Artemis II moon mission engulfed by debate over its controversial heat shield

Heat shields are crucial: when spacecraft reenter Earth's atmosphere, they heat up, burning through the sky like a shooting star. Without a protective layer, any living thing inside a returning spacecraft would be exposed to temperatures about half as hot as the surface of the sun, or 5,000 degrees Fahrenheit (2,760 degrees Celsius). In Orion's case, the heat shield is made of Avcoatthe same material that protected the Apollo capsules, with a key structural difference.
