NSF lists this award's end date as 31 August 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2029.

Abstract

Comets are remnants from the early solar system that retain the volatiles (ices) from the cold regions where they formed. Their nuclei were among the first objects to accrete in the early solar nebula, and they likely formed at diverse distances from the young Sun. The primary science objective of this project is to better disentangle the natal (cosmogonic) heritage in cometary volatiles from signatures of possible…
