Web11 jul. 2024 · This is also known as a HOT gas! Over several minutes (for a space capsule on a proper re-entry) the capsule gradually loses speed as its kinetic energy is transferred to the gas and it slows down. During this time the gas in front of the capsule forms a layer of highly compressed air forms known as a shock wave.
