First look at crew module! Silver color is from a coated kapton tape serving 2 purposes, thermal barrier/reflection and conduction of static charge across surface. Conduction is necessary as flying through space, crossing magnetic field lines, generates charge that if not managed could short out vehicle.u
Under the tape, CM backshell is covered in nonconductive ceramic thermal tile like Space Shuttle belly. 3rd pic is tile from #Orion EFT1 flight test, tape was unnecessary. #NASA #Artemis
