LaunchLedger

LaunchLedger is a web app (with a lightweight mobile companion) that turns messy, scattered launch information into a clean, searchable “ledger” of global rocketry activity. It aggregates upcoming and historical launches, vehicle configurations, payload manifests, delays/scrubs, NOTAM/notice links, launch site constraints, and post-flight outcomes into a single timeline per provider and per rocket family. The core value is reliability and provenance: every data point is sourced, time-stamped, and change-tracked so users can see what changed and when (e.g., payload swaps, window shifts, engine variant updates). It’s built for people who need accurate launch ops context without doomscrolling social media. This is not a generic “launch calendar”; it’s a structured database with alerts, exportable datasets, and a simple API tier for power users. Expect some gaps early—data quality is the hard part—but the product is useful even at partial coverage.
