ok, work this out.

There are 17.3 million millionaires living in the usa.NOW ,American people love the moon in fact they think they own it.Its my guess that every American would love to have their ashes scattered on the Moon when they depart this life.So lets say 10% of the 17.3 million millionaires signed up to have their ashes scattered ,and agreed to pay one million dollars each for the privilege,NASA could be the undertakers and and collect the billions to finance their space program ,and business would be brisk .
someone else can do the math but it would be some pile of money collected ,until it went out of fashion .they could charge 2 million for a mars funeral.and take the ashes to the moon when ever they decide to go to it.
17.3 million millionaires ,thats a big number
