Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 August 2027.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2027.

Abstract

Dark matter makes up most of the universe, but scientists still don’t know what it’s actually made of. A new award supports DarkSide-20k, a major U.S.-led global experiment designed to hunt for this mysterious particle. The project will strengthen American leadership in physics while advancing cutting-edge technology such as ultra-sensitive detectors, cryogenic (super-cooling) systems, and low-radiation materials.…
