nature : meteorite entered the atmosphere after erosion and fission phenomenon. In the field of space means that when flying objects (such as missiles, space vehicles, etc.) reenter the atmosphere under the heat from the thermo-chemical and mechanical process of solid surface caused the mass transfer phenomenon. Satellites and spacecraft have heat-resistant shell ablative material. When recovery satellite enters the atmosphere, air mechanical heating, the surface temperature of up to thousands of degrees of heat. The ablative material is heated or sudden high temperature combustion decomposition layer of carbonaceous remnants of heat insulation layer to take the role. Protection satellite structure without damage.
