[FPSPACE] Dual Orion capsules studied for mannedasteroid missions

[David Portree]

Didn't Arthur C. Clarke put his first space elevator in Mars orbit?

We won't start with an Earth-GEO elevator, anyway.
 
It makes much more sense to build rotating skyhooks o[erating in lunar orbit, starting with
small payloads to and from the lunar surface -- 200-400 KG or so. Sample retrieval canister
size. Single suited astronaut size. Well within available material strength.

Jens:
 
We won't go after a space elevator anchor point until we need a space elevator. We won't grab an asteroid and park it on the off-chance that we'll decide someday to build one. Will we need a space elevator any time soon? I'm sorry, I just don't see it, as cool as it would be.
