User Interface DeltaVMap

[Maxi]

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.

• 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.

All numbers are closed-form patched-conic estimates (Hohmann transfers with Oberth-combined departure and capture, no iterative solver), so the whole map is fast and cached once per session.

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

1. Install StarMap (required).

3. Extract into Documents\My Games\Kitten Space Agency\mods\DeltaVMap\.
4. The game auto-discovers new mods on next launch.

Open the map from the View menu in flight, or the Delta-V Map tab in the editor.

DeltaVMap v1.1.0 - Cleaner labels at overview zoom

Changes

• Map labels now sit on a dark background plate, so transfer and ladder lines never make text unreadable
• Zoomed out, each body shows one short name label (Saturn) instead of one label per rung; zooming in restores the full labels
• Far-out overviews hide moon names entirely (the root's own moons stay visible), leaving planets, the route and the +N group counts
• Hovered, root, you-are-here and on-route labels always show in full

Compatibility
Tested against KSA build version 2026.6.3.4568.

Installation
Extract into Documents\My Games\Kitten Space Agency\mods\DeltaVMap\.
Requires StarMap.

DeltaVMap v1.3.0 - Support for Interstellar trips and every star system

Changes

• Shows every star system of the loaded universe. In the new interstellar systems, Alpha Centauri, Barnard's Star and Tau Ceti sit apart from your home map as graphs of their own, joined by a dashed interstellar line. Click a system to open it and see its stars and planets.
• Plans interstellar trips as ordinary routes. Click a star system, star, planet or moon in another system, then pick the cruise speed (0.001 c, 0.01 c, 0.1 c, a slider, or MAX for the fastest trip your vessel can pay for). The route panel shows the departure and capture burns and the plane change, the coast time, the cheapest trip at any speed and the total against your vessel's delta-v.
• Adds a fuel estimate for interstellar trips using the interstellar burn model for an antimatter drive, the rocket equation for any other vessel.
• Opens the stock Transfer Planner on its Interstellar plan with the destination system already selected.
• Follows your vessel when it crosses into another star system. A System menu shows any star system, and the search finds bodies in all of them.
• Moves the map into its own top-level "Delta-V Map" menu, in flight and in the editor.

Compatibility
Validated against KSA build version 2026.10.7.5541.
