DeltaVMap is an interactive, auto-generated delta-v subway map and transfer-window planner for Kitten Space Agency.
It reads the loaded solar system live, so it works with any system, stock or modded, with no per-system setup, and tells you both where you can go, for how much delta-v and when to leave.
Features
Delta-v subway map
A metro-style map rooted on the body you are currently in. Shift-click any body to re-root the whole map around it; it also re-roots automatically on the next open after an SOI change.
Transfer windows
The timing companion to the map. For the root body and every sibling sharing its parent, a live phase clock and list show the optimal phase angle, the current phase, a countdown to the next window, the synodic period, the ejection angle and the transfer time.
A separate, opt-in layer draws the same data in the game's 3D map mode: the optimal-departure marker on the destination's real orbit (where it will be when the window opens), the planet-star-planet phase angle, and an ejection-angle gizmo at the departure body.
Layout modes
Three layouts, switched from the on-canvas toggle on the top-left or the Options menu: a cumulative-down metro tree (default), a gravity-well row of vertical wells on a low-orbit spine, and a force-directed spring web.
Installation
Version: 1.0.0 (tested against KSA 2026.5.12.4510)

- Click any body to plan a route from your current state: total delta-v, a per-segment breakdown and transfer time.
- Toggles for launch-from-surface, landing, aerobraking, plane change and a return trip, plus a piloting-margin percentage to budget for non-optimal flying.
- A bar compares the selected route against your ship's actual staged delta-v.
- Node-symbol vocabulary with a legend, search / focus / isolate, and automatic minor-body aggregation so a dense system (thousands of asteroids) stays usable.
