EPISTEMIC DEMARCATION // Tier 5 (Terawatt Systems)

Constitutional Demarcation: A Research Fabric is a bounded epistemological architecture. Structural formulation, digital execution, and proof-assistant replay declare local invariants; they do not constitute unverified physical validation.

Research / Engineering Question ​

How can solar generation, high-density compute, thermal rejection, communications and orbital operations be designed as one coupled modular infrastructure rather than as loosely integrated spacecraft subsystems?

Architecture ​

A reference TerraFab node contains:

  • deployable high-efficiency solar arrays;
  • central compute and power-electronics module;
  • power management and distribution;
  • deployable radiator manifold;
  • attitude-control / orbital-control subsystem;
  • high-bandwidth RF or optical downlink;
  • scalable truss and modular attachment architecture.

The critical systems constraint is the coupling among power, compute and heat rejection: increased compute is useful only if generation, thermal rejection and communications scale with it.

Core Invariants ​

  1. energy generation and compute load must close under a complete power budget;
  2. heat generation must remain below validated rejection capability;
  3. attitude/orbital authority must remain sufficient under deployed-array geometry;
  4. communications throughput must be reported separately from compute throughput;
  5. launch mass and deployed structure remain explicit constraints;
  6. orbital node performance and lunar-extension concepts retain separate maturity states.

Reference Model ​

The current architecture illustration specifies a 100 MW electrical array reference node, radiator temperatures of 400–600 K, a $150/kg launch-cost target, and $1,850/kW node CapEx excluding launch.

These are reference-model assumptions / targets, not demonstrated or independently validated system performance.

The same model labels:

  • orbital node: TRL 4
  • lunar expansion: TRL 2

These are programme reference classifications.

Public Status Boundary ​

TerraFab is a systems architecture and feasibility programme. The page must not imply that a 100 MW orbital compute node has been built, launched or economically validated. Launch economics, thermal feasibility, radiation tolerance, assembly, servicing and communications remain major engineering gates.

Research / Implementation Path ​

  • close one reference orbit and mission profile;
  • perform end-to-end mass/power/thermal budgets;
  • qualify compute hardware under radiation and thermal constraints;
  • validate deployable arrays/radiators;
  • evaluate optical/RF communications;
  • model assembly and launch cadence;
  • progress through subsystem demonstrators before integrated orbital validation.
