A vast interplanetary transport network has been established within our solar system to facilitate efficient movement between celestial bodies. This network comprises two primary transit routes: the inner route connecting Mercury, Venus, Earth, and Mars, and the outer route connecting Jupiter, Saturn, Uranus, and Neptune. These routes intersect at several asteroid belts designated as transfer hubs, crucial for transferring cargo, passengers, and refueling spacecraft.
The infrastructure of the network includes terminal stations located on the outermost planets of each route, represented as squares on the map. Key asteroid belts where the inner and outer routes intersect serve as transfer hubs, depicted as diamonds. Additionally, there are smaller waystations positioned between terminal stations and transfer hubs, marked as dots on the map. Spacecraft within this network operate exclusively on either the inner or outer route and never switch between the two. Travel times between adjacent waystations vary significantly between the inner and outer routes: the average travel time on the inner route is approximately 30 Earth hours, while on the outer route, it averages around 72 Earth hours. At transfer hubs, spacecraft typically spend about 6 Earth hours for operations such as cargo and passenger transfers, as well as refueling.
