Promise Ledger
Director General of Roscosmos from 2022 to February 2025. These are the dated public commitments by Yuri Borisov that we could source to a primary, with what happened. Roles are as of the date each was said.
2 entries: 1 revised; 1 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.

Context: Kremlin transcript of President Putin’s meeting with young scientists and space industry specialists (RSC Energia); Putin asked when the station segment shown could be launched. Putin then said: "Vladimir Putin: The first segment must be orbited in 2027."
Later dated commitments for the same milestone

Outcome: Not launched as of 2026-09-26; the deadline has not passed. TASS reported on 2026-06-30 that Roscosmos projects the first module for 2028; we did not find that projection in a Roscosmos primary source, so it is not recorded as a revision.
