Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. Atmospheric entry may be uncontrolled entry
Heat shield
…heat shield consists of a protective layer of special materials to dissipate the heat. Two basic types of aerodynamic heat shield have been used: An ablative heat shield consists of a layer of plastic resin, the outer surface of which is heated to a gas, which then carries the heat away by convection. Such shields were…
