Promise Ledger
United States space agency. These are the dated public commitments by NASA and its people that we could source to a primary, with what happened.
15 entries: 4 met; 1 missed; 9 revised; 1 withdrawn.
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.
