The Space Shuttle design presented many Thermal insulationchallenges. The system not only had to perform well, it had to integratewith other subsystems. The Orbiter s surfaces were exposed toexceedingly high temperatures and needed reusable, lightweight,low-cost Thermal Protection . The vehicle also required low vulnerabilityto orbital debris and minimal Thermal conductivity. NASA decided tobond the Orbiter s Thermal Protection directly to its aluminum skin,which presented an additional challenge. The External Tank required insulation to maintain the cryogenic fuels,liquid hydrogen, and liquid oxygen as well as to provide additionalstructural integrity through launch and after release from the challenge and solutions that NASA discovered through tests andflight experience represent innovations that will carry into the nextgeneration of space InnovationsThermalProtectionSyst
concentrated strain isolation pad loads evenly into the weaker, unmodified reusable surface insulation tiles. NASA faced a greater structural design challenge in the creation of numerous unique tiles. It was necessary to design thousands of these tiles that had compound curves, interfaced with thermal barriers and hatches, and had penetrations for
