Promise Ledger
Launch vehicles (Alpha) and lunar landers (Blue Ghost). These are the dated public commitments by Firefly Aerospace and its people that we could source to a primary, with what happened.
5 entries: 2 met; 1 revised; 2 pending.
Plain counts, not a grade or a ranking. A short record is not a complete one. Updated Sep 28, 2026; each entry shows the date it was last checked against its source; scoring rules on the methodology page.
This first release is a selection, and a short record is not a complete record. Each programme milestone enters the ledger at its earliest dated public commitment we can find in a primary source, for governments and companies alike. Later dated commitments for the same milestone are shown on that one entry as a revision chain, oldest first, rather than as separate entries.
