METHODOLOGY

Launch history and subsystem outcomes aggregate from AstraVeris's launch_events table with Wilson 95% lower bounds on success rates. ARI scores come from the 11-factor composite (/finance/methodology/). Constellation counts derive from the live CelesTrak/GCAT object catalog. Gov contracts from USAspending.gov awards; private deals from deduplicated pipeline deal extraction. Absence of a row means "not tracked" — we never fabricate. See /methodology/ for the full data model and /data-licensing/ for licensing terms.
