Description
Gaia DR4 is planned for December 2026, covering the five years of nominal Gaia mission, and will include 'everything'. It will consist of more than 140 tables and of the order 500 TB of data. We give a brief overview of the various data products and how they are organized. With respect to Gaia DR3, the uncertainties will improve significantly and the release now includes the epoch data for astrometry, photometry and spectroscopy, allowing a much more flexible use of the data. Gaia DR5, for the full ten years of mission, will give another leap in precision but is not expected before the end of 2030.
