Promise Ledger
Private astronaut missions and commercial station modules. These are the dated public commitments by Axiom Space and its people that we could source to a primary, with what happened.
3 entries: 1 met; 2 revised.
Plain counts, not a grade or a ranking. A short record is not a complete one. Checked against sources on Sep 26, 2026; 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.
