Simulation Methodology

This simulation models the economic crossover point between Earth-based manufacturing with launch to space versus in-situ resource utilization (ISRU) manufacturing. It addresses research question RQ-1-12: At what scale does in-space manufacturing become more economical?

  • Earth costs include manufacturing with learning curve effects plus launch to deep space
  • ISRU costs include high initial capital investment plus operational costs per unit
  • Learning curves reduce per-unit costs as cumulative production increases
  • Monte Carlo sampling captures uncertainty in launch costs and ISRU capital requirements

Key trade-off: ISRU requires significant upfront investment but avoids ongoing launch costs; Earth manufacturing is proven but launch costs dominate at scale.

Key Assumptions

Earth Manufacturing

  • Fixed annual production capacity
  • Learning curve: 80-90% (cost per doubling)
  • Launch cost: $500-5000/kg to deep space

ISRU Manufacturing

  • Seed factory capital: $10B-200B
  • Ramp-up period: 1-15 years
  • Learning curve: typically slower than Earth
