Gas stations in space. I like that. Nice and easy to read in the first half and then technical, but still understandable in the second half. And works with SLS, not against, well sign me up!
Bah, we all agree on something? How long can this last?
Two part article. First part on NASA's internal notes on Prop Depot Interest via L2 and a presentation we have on there about a leading concept (the "Simple Depot")..http://www.nasaspaceflight.com/2011/08/nasa-interest-interplanetary-highway-supported-propellant-depots/
Now we need to see a ground up cost analysis to see how much money will be saved (or not saved). How much will a pound of fuel at the depot cost? How many development dollars will be spent? The list goes on.
LEO depots - by themselves - do not make an "interplanetary highway"Lagrange point depots and depots in orbit around other celestial bodies (Mars, for example) are necessary if we are to claim to have an "interplanetary highway"
