Steady-state megawatts with tenths-of-gigawatt bursts characterize space-nuclear-power requirements for critically essential future missions. These awesome numbers imply great power densities and ultrahigh operating temperatures - attainable with thermionic energy conversion (TEC). But such capabilities involve a gamut of materials ranging from high-vapor-pressure liquid metals through refractory ceramics to extremely low-vapor-pressure ultraalloys with near-maximum melting points, strenghts and stabilities. Aspects of the material spectrum related to ultrahigh-temperature TEC combine to project an important temporal perspective of the space-nuclear-power picture. Considerations of these extreme material implications comprise the background, subject and viewpoint of this presentation.
