Abstract

Starting with a conceptual thermal model of LUVIOR-A, provided by NASA/Goddard Space Flight Center, alternate concepts of operations are explored. A candidate technology was identified to use solar power for rough first stage heating. That innovation reimagines what functions a solar array can have in a large telescope architecture. By combining electricity generation, stray-light control, and thermal control into one agile deployable structure, the heater power requirements could be improved by reducing the inefficiency of solar power conversion.
