A Maintained Ice-Shaft Elevator Station for Europa: Creep Closure, Reaming Interval and Capsule Hoist Budget

The system named in the title is developed here as a worked design, derived from the physics of its operating environment and reported throughout as SIMULATED, NOT MEASURED. The station is civilian scientific infrastructure providing repeated, scheduled access to Europa's ocean for instruments and samples in support of peaceful research. The deposited computation script produces every number in the paper from stated inputs; among its results are basal closure rate of 39.6 millimetres per year, reaming interval of 7.6 months and round trip cycle time of 5.6 hours. The study assembles component budgets for mass and power, examines how the design behaves away from its design point, and closes with an explicit statement of what the sizing does not establish.
