Footfall by Larry Niven is the best example of city-ships in line with Project Orion.  Basically the bigger they are the better.  Big metal plate with a city on top and nuclear bombs exploding underneath.  And the project started in the 50s.  [http://en.wikipedia.org/wiki/Project_Orion_(nuclear_propulsion)]--[[Special:Contributions/173.245.54.11|173.245.54.11]] 04:53, 11 May 2014 (UTC)

Before restarting Orion, why not start with a more modest goal: a facility to ''assemble'' spacecraft on the moon from parts made on Earth? Even without the mining, it'll mean we can launch a craft from Earth in several smaller rockets instead of one big one.
