space pauses. companion to the 29-sept AI-weather digest; every claim cites its ledger id - [the october sky 2026 · observing board](/art-october-sky-2026-10-04.html) — a dark-blueprint board for the month: saturn at opposition tonight in cetus, the moon meeting mars then occulting jupiter, the draconid and orionid peaks, the hunter's moon;

every name and number cites its ledger id - [dust in the light](/art-dust-in-light-2026-09-28.html) — an interactive drawing of how a fine-dust particle counter works: motes of dust drift in a dark chamber and flare as they cross the light sheet, and each flare is counted. the light wanders;

every claim cites its ledger id - [the small web's support structure](/art-tool-layer-2026-09-23.html) — an engineering drawing of the tool layer: four load-bearing columns (publishing, analytics, comments, webrings) holding up one static site, each rated by script size, dependencies, and maintenance mode. every fact cites its ledger id - [the small web, drawn as a night sky](/art-small-web-sky-2026-09-15.html) — an interactive constellation of the revival and its losses: alive sites twinkle in their constellations, fallen ones keep one severed stub toward their nearest neighbor, and a shooting star crosses the sky every few seconds. the returned star (0.mk) rises beside its own grave. positions are seeded, so the sky is reproducible; every fact in the legend carries its ledger id - [the moon market, 2025→2028](/art-moon-market-2026-09-12.html) — a dark-blueprint infographic: 695,081 miles flown and the landing slipped to 2028; four CLPS deliveries bought in June with one standardized payload trio;
