Keith’s Update: First NASA Goddard sends an internal email to staff saying “unlike previous large-scale Center reconfigurations, which occurred over a number of years, all planned moves will take place over the next several months and will be completed by March of 2026.” Then they put this thing out for the public minutes late that makes no mention of the accelerated timeframe as if they had planned this whole thing years ago. So I added a footnote 😉

The posting date for this article is from 2022. It doesn’t appear to be related to the budget cut building closures, only the previous Master Plan.
There was a Master Plan from 2008 (still have the video), and nearly mapped all of this out.
