AVCOAT was used for the heat shield on NASA's Apollo command module. [4] In its final Apollo form, this material was called AVCOAT 5026–39. Although AVCOAT was not used for the Space Shuttle orbiters, NASA again used the material for its Orion spacecraft [5] first for the initial Orion test and then for a different type of heat shield for the later Orions.
The first reentry test of a PICA-X heat shield was on the Dragon C1 mission on 8 December 2010. [35] The PICA-X heat shield was designed, developed and fully qualified by a small team of a dozen engineers and technicians in less than four years. [33] PICA-X is ten times less expensive to manufacture than the NASA PICA heat shield material. [36]
The key to a reusable shield against this type of heating is very low-density material, similar to how a thermos bottle inhibits convective heat transfer. [citation needed] Some high-temperature metal alloys can withstand reentry heat; they simply get hot and re-radiate the absorbed heat.
