"Geoff have you meet Spudis or Zubrin? Spudis has a following just not as transparently as Zubrin with the Mars Society. But, whether you believe it or not they have similar personalities."

I haven't met Zubrin or Spudis. I have read books by both of them.

"I'm pretty sure when Spudis has his data he will no longer care so strongly to promote the continued return to the Moon. This is what I meant by "abandoned". This is me projecting what his colleagues have said about him and his goals."

Are some of these colleagues you mentioned, members of this less transparent group? And is it possibly that they will be disappointed?

Can anyone join this less transparent group? Do they have buttons, member cards, or something?
