Here's a suggestion. Why not email NASA and ask them for details
about the how much extra it costs placing those ashes on the craft
for each each tax payer.

I would suggest that there is no additional cost. The launch vehicle is
capable of launching x number of pounds. If the launch weight of the
vehicle is under that weight, you could fill up the rest of the vehicle with
tire weights and launch it, and it would not cost any more to launch.
