WebOne of the first and continuing applications of optical coatings is to maintain a safe and consistent internal temperature of electronics and optics in spacecraft instruments, through sunlit and dark cycles. Simple in construction, thermal control coatings involve the clever use of the optical and thermo-physical properties of materials. Web1. dec 2024 · The pigments for the “optical solar reflector”-class thermal control coatings (TCC) of spacecraft (SC) have a number of crucial properties: namely, high value of the reflectance coefficient in the solar spectrum and high stability under the space radiation. These conditions are expressed via a small α s value and its high stability when flying.
WebThermal control coatings are an essential part of spacecraft systems. Typically, these coatings are directly exposed to the space environment, which means they must be designed and applied in a manner that can withstand exposure to radiation, ultra-violet light, thermal cycles, etc. In the case of the Europa Clipper mission, the thermal control … WebSpacecraft Thermal Control Coatings References The successful thermal design of spacecraft depends in part on a knowledge of the solar absorption and hemispherical …
