Lunar night survival, while being a technical design challenge, also has an impact on mis-sion planning and execution during the flight system development phases (Phases A-D). Depending on mis-sion objectives, different locations on the lunar surface result in different challenges to technical formulation of a comprehensive mission design and implementa-tion. Equatorial regions have temperature extremes between day and night (<100K to >380K) but are somewhat cyclical and predictable. Polar regions can have milder thermal environments in terms of overall surface temperature swing and opportunities for ex-tended durations for solar power but pose unique chal-lenges in temporal and spatial availability of both sun-light and direct-to-Earth communications. Options for surviving the night will depend heavily on mission objectives, lunar location and program cost and schedule constraints.
