The New Private Space Race

[backtrax]

Don't forget the Orion project. An early concept of nuclear-propulsion. Still a viable way to achieve great speeds needed to travel to and capture far-flung asteroidal resources.
Perhaps best suited the delivering supplys to missions that need years of reserves, such as planned permanate bases on mars. And Orion-based supply-ships may even be reuseable...returned Via lo-V trajectory and 'parked' in lunar orbit to await reconditioning and resupply.
