Rubin's early-science plan gives the LSST start as 2026-06-29 and says processing one year of data "is estimated to require approximately one year", which "implies an expected DR1 delivery approximately two years after the effective start" - while warning the boundaries are set by "survey performance and scientific readiness rather than a fixed calendar date".

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
