WebReentry thermal protection is shielding that must be fitted to a spacecraft, such as a manned capsule or the Space Shuttle, if it is to survive the intense heat generated during … The concept of the ablative heat shield was described as early as 1920 by Robert Goddard: "In the case of meteors, which enter the atmosphere with speeds as high as 30 miles (48 km) per second, the interior of the meteors remains cold, and the erosion is due, to a large extent, to chipping or cracking of the suddenly heated surface. For this reason, if the outer surface of the apparatus were to c…
