claims_extracted:
  - "power is the binding constraint on all space operations because every capability from ISRU to manufacturing to life support is power-limited"
  - "in-situ resource utilization is the bridge technology between outpost and settlement because without it every habitat remains a supply chain exercise"
  - "MOXIE proved ISRU works on another planet by extracting oxygen from Mars CO2 at twice its design goal and 98 percent purity"
  - "nuclear fission is the only viable continuous power source for lunar surface operations because solar fails during 14-day lunar nights"
  - "space-based solar power economics depend almost entirely on launch cost reduction with the break-even threshold near 10 dollars per kg to orbit"

# In-Space Manufacturing, Power Systems, and Water/Resource Processing

Research synthesis on the infrastructure layer of space development. Power as the binding constraint, solar vs nuclear trade-offs, ISRU technology status (MOXIE demonstration), water extraction and processing requirements, space-based solar power economics, and the infrastructure dependencies that determine the sequence of space industrialization.
