Define the thermal control architecture for Vast's lunar surface elements - trading passive, heat pipe, pumped fluid loop, and thermal storage approaches against mass, power, complexity, and dust exposure

Size and place radiators for the lunar surface environment, accounting for diurnal sink temperature swings, albedo and lunar IR loading, terrain and self-view blockage, and latitude-driven constraints

Own the survival thermal case through lunar night - heater power budget, thermal mass and phase-change storage strategy, and dormancy and wake-up thermal states

Own the habitat, airlock, and node thermal control - cabin temperature and humidity control, condensing heat exchanger, coolant loop architecture, and depress/repress thermal transients

Build and maintain the detailed system thermal models, contribute reduced-order models to Vast's design, simulation, and validate against Thermal Desktop, SINDA/FLUINT, or equivalent

Own the thermal budget: min/max predicted temperatures per component against qualification limits across launch, cruise, descent, landed day, landed night, and off-nominal conditions

Select thermal coatings, MLI, heat pipes, thermal straps, isolators, heaters, and RTDs for the lunar environment, with explicit accounting for regolith dust deposition, abrasion, and UV degradation of end-of-life optical properties

Plan and execute TVAC and thermal balance test campaigns (chamber and shroud requirements, solar and IR simulation, cold-case survival demonstration, test profiles and success criteria), then correlate models to test data

Establish the thermal design standards, margin policy, and lunar environment definitions Vast's lunar hardware will be built on, and support design reviews, drawing checks, and NASA technical deliverables
