I wrote way back when about the amount of funding that NASA and the NSF has provided for SETI since the program at NASA was canceled in 1993. It turns out that there have been a few grants scattered over the years, but they amount to not even enough to fund two people over that time.

Since then, there have been some successful grants! In addition to the NASA Technosignatures Workshop in 2018, there have now been a few grants to external PIs.

Below is a (continuously updated) list of the ones I know about:

NSF:

• AST-2003582: “Participant Support for the first Penn State SETI Symposium” $49,400. PI: Jason Wright, 1/1/2020–12/31/2021, extended until symposium meets
