Since the gravity of small moons can easily be escaped by tether would it be cheaper to send fuel from far away from a moon like titan, or to rocket it from earth?
Here’s the plan.
Fuel is the biggest drag on space travel. Most of the expense is wasted on wind resistance of getting rockets into space. With a reactor and water at the end of a tether on the Moon, Mars or even Titan, we can make that fuel for decades, and put it just above the atmosphere for space plane to rendezvous with. With only two launches one for the tether and one for the reactor you could cost effectively replace the space shuttle with monthly flights into space. By taking the risk of launching one reactor in space, you could increase safety, and reduce the expense, of going into space enough to reach Mars in less than a decade. All the components exist today, are possible today, and could be done tomorrow.
