A Spherical Pressure-Vessel Habitat Module for the Venus Surface: Shell and Buckling Sizing

This study sizes a Spherical Pressure-Vessel Habitat Module for the Venus Surface for operation in the Venus surface environment and reports the result as SIMULATED, NOT MEASURED. The design is developed from stated physical relations and a shared environmental basis, and every performance figure is computed by the deposited script rather than asserted. Among the computed results are vessel radius of 3.0 metres, net external pressure of 9098675 pascals, membrane thickness from stress alone of 0.0388 metres, buckling safety factor at membrane thickness of 4.44 as a ratio. Mass and power budgets are assembled from components so that they can be audited, off-design behaviour and materials uncertainty are discussed openly, and the limits of the sizing are stated in full. The system is a civilian science and construction design intended for a robotically serviced surface station.
