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.
- Ground links as a limit on orbital computeTuryshev's preprint (April 2026) concludes that general compute for terrestrial users closes only for low Earth-coupled communication intensity, high utilisation, long lifetime and very low launch-plus-build cost.2026-04-29 · publication · Stated in source · Supported Inspect claim & evidence ↗Ground links as a limit on orbital compute: propositions page →
- Heat rejection as a constraint on orbital computeTuryshev's preprint (April 2026) treats radiator area as part of its base-case mass model, with about 2,500 m2 of radiator for 1 MW of IT power, and concludes that general compute for terrestrial users closes only when several conditions hold together.2026-04-29 · publication · Stated in source · Supported Inspect claim & evidence ↗Heat rejection as a constraint on orbital compute: propositions page →
- Orbital compute costs more than compute on EarthTuryshev's preprint (April 2026) finds that matching a terrestrial benchmark of 10-40 thousand dollars per kW allows only 250-1,000 $/kg for launch plus build, 3.4-13.5 times below the current public Falcon 9 dedicated launch price alone.2026-04-29 · publication · Stated in source · Supported Inspect claim & evidence ↗Orbital compute costs more than compute on Earth: propositions page →
