Documentary relations
Each relation is listed separately. Citing, crediting and reporting the use of a method are different acts, and none of them shows agreement or influence by itself.

Propositions whose criterion a passage of this document meets. The record says what the text states, in its register; it is not evidence that the proposition is true.
- Falling launch prices as a condition of orbital computeThe Suncatcher paper (November 2025) argues that if launch to LEO reaches $200 per kilogram, launch cost amortised over spacecraft life could be roughly comparable to terrestrial data-centre energy costs per kW.2025-11-22 · publication · Stated in source · Supported Inspect claim & evidence ↗Falling launch prices as a condition of orbital compute: propositions page →
- No practical repair of hardware in orbitThe Suncatcher paper (November 2025) states that replacing failed TPUs by technicians, simple on Earth, is impracticable in space, and that redundant provisioning is the simplest solution.2025-11-22 · publication · Stated in source · Supported Inspect claim & evidence ↗No practical repair of hardware in orbit: propositions page →

- Radiation effects on computing hardware in orbitThe Suncatcher paper (November 2025) reports proton-beam tests in which Trillium TPU HBM showed irregularities after 2 krad(Si), about three times the authors' five-year requirement of 750 rad(Si).2025-11-22 · publication · Stated in source · Supported Inspect claim & evidence ↗Radiation effects on computing hardware in orbit: propositions page →
