Heat shield

A heat shield is a protective barrier designed to withstand and dissipate intense heat. In spacecraft and rockets, it prevents high temperatures from damaging the vehicle and its instruments during re-entry into Earth's atmosphere or when passing through hot environments. The shield absorbs, reflects, or radiates the heat away from the spacecraft, ensuring safe operation and protecting sensitive components. Materials used are often heat-resistant and durable, such as specialized tiles or ablative substances that can withstand extreme temperatures. Overall, the heat shield is essential for safely managing thermal risks during high-temperature conditions.
