Interplanetary Launch
The launch loop is intended for launch velocities below escape, and vehicles of 5 tonnes or less. Interplanetary expeditions will require far more velocity and far larger vehicles. Large interplanetary vehicles will be assembled in orbit from many - perhaps thousands - of 5 tonne components, and fueled for escape (and eventual arrival) with hundreds of additional deliveries of propellant.
