Two craft. One design.
Horizon F-01 and Horizon F-02 share a compact, tapered charcoal-and-orange form. The full name and ferry number identify the individual vehicle. They are separate craft assigned to the carrier Horizon / CT-01.
A ferry can land, be serviced and return to orbit using chemical propulsion. Horizon’s interplanetary propulsion belongs to the carrier; the carrier does not land beside the settlement.
The route continues indoors
After docking or landing, passengers move through a checked vestibule and an enclosed corridor. Flight crews attend to seals, garments and the route before the ordinary work of welcoming a family begins.
A ferry turnaround includes the condition of the vehicle and its capacity to make the next flight. The arrival hall, pressure connection and service bay are parts of that working sequence.
