Samples of rad-hard PLLs from Peregrine are $500 each so small rad-hard FPGAs must be several thousand dollars each.

Actel has just introduced "rad tolerant" flash-based FPGAs. These use the *identical* silicon die as the commercial ProASIC 3 devices. These are what we specified (and purchased) for the SDX for Eagle.

Good News! Any idea of the price for the price for flight-quality parts? I'm about to unveil my latest (for EAGLE@GEO) payload idea and it is heavily dependent on the use of FPGA's for polyphase filter bank (PFB) and digital cross-bar (DXB); details to follow.
No, but it'll be darned expensive with ceramic packaging and "bga" bumps made of stand-up pillars.
ITAR WARNING!!!!
If you are not a US citizen it may be a criminal offense to read the next sentence!
I'd fly the plastic part in a TQFP, personally.
END OF ITAR WARNING!!!!!
Note that the Actel Flash FPGAs aren't as full of DSP features as the SRAM-based parts from Xilinx et al.
