Orbital handoff
At the edge of night, a cargo tug slips out of parking orbit carrying less propellant than old mission planners would have accepted. It leaves lighter because part of the mission is already waiting for it: relay nodes, precision timing, synchronized sensing, service platforms, and coordinated control spread across the route ahead. The craft is still bound by real constraints, but it is no longer hauling all of its fate onboard. It is entering a managed medium.
The same logic pushes further. Once orbital infrastructure is trusted enough to hand off guidance, stability, and correction, engineers begin probing a stranger question: whether the effective paths that signals take through an environment can be shaped as deliberately as the vehicles moving through it. That horizon stays later and harder, but it belongs here because space has stopped feeling like empty distance and started feeling like engineered coordination.
