re: Spinoffs are the weakest argument
Carl Sagan said in his 1994 book, Pale Blue Dot, that if you want to find
a cure for cancer, put the money in cancer research. Don't put it into
space and then try to make space spinoffs do the work.
Everybody wants to know what anything anywhere has to do and can
do for them. And it has to be NOW.
I say, you're lucky the Universe let you happen at all. Now be patient.
