Space Transport and Engineering Methods/Interplanetary With a
network of systems developed around Earth and the Moon, the next
step is to extend the network out to Mars and the Main Asteroid
Belt. A similar process of setting up seed factories and adding
facilities is followed as before. System Concept  The system
concept has the following main parts: - Use free flying electric
thruster powered vehicles to reach new locations that have
useful resources. - Set up seed factories in each location to
build up industrial capacity, including more ships and seed
factories for the next location. - Produce fuel, life support
supplies, and habitats at each location so they can be occupied
permanently. - Build more Skyhooks to provide fast velocity
changes, but get the benefit of electric propulsion efficiency.
High Earth Orbit Skyhook  In a previous step we defined a Low
Earth Orbit (LEO) Skyhook with a tip velocity of 2400 m/s. Since
it's orbit velocity is 7474 m/s, at the top of it's rotation it
could release a cargo
