A space fleet follows a route, with a travel time and an Aether cost. The Pillars project ground units without a conventional space journey or Aether consumption: most missions are instantaneous and cost RT; Exploration and Hacking each have their own duration. See Launching and tracking an exploration and how a hacking mission unfolds.
For fleet-specific calculations, see travel time, reference speed, speed setting, and Aether consumption. The projection cost calculation is detailed in cost components.
Example
A Transport via the Pillars does not work like a space convoy: the main concern is not travel time, but projection cost.
