03/02/2017 Gaia DR2 Schedule
The schedule leading up to Gaia DR2 (Data Release 2) has recently been revisited by the DPAC project office, together with ESA. Some necessary changes in the data processing, together with an improved data processing flow, have led to a revised schedule which is believed to be firm as it is based on true performance testing and availability analysis of hardware and people. The new release date will be April 2018. Further details are available here.
