An accelerated boundary correspondence (ABC) is solved for the de Sitter moving mirror cos mology. The beta Bogoliubov coefficients reveal the particle spectrum is a Planck distribution with
temperature inversely proportional to horizon radius. The quantum stress-tensor indicates a con stant emission of energy flux consistent with eternal equilibrium, while the total energy carried
by the particles remains finite. The curved spacetime transformation to flat spacetime with an
accelerated boundary is illustrated, and also shown for Anti-de Sitter (AdS) spacetime
