Kerbal Atomics

This part pack is designed to provide some new nuclear thermal rockets for your spaceship-building pleasure. There are four new engines, two in the 2.5m size class and two in the 1.25m size class. They are fuelled with LiquidHydrogen, and in some cases can use Oxidizer to boost their thrust at the cost of specific impulse. Liquid Hydrogen is less dense than liquid fuel, so for the same Delta-V, you will need more tank volume. 

 

To store your liquid hydrogen fuels, I've provided ModuleManager/InterstellarFuelSwitch configs that allow you to change the contents of stock tanks between LF/O, LH2/O, LF, O and LH2. These should work with most mod tanks, but no promises. However, Liquid Hydrogen is very temperamental and without the proper storage it will slowly evaporate ("boil off"). Therefore, I provide special cryogenic tanks bundled with the mod, that use a small amount of Electric Charge to stop the evaporation.

 

This mod is designed to synergize well with Cryogenic Engine 0.2.0+, and with the various Near Future Technologies mods I make.

 

Known Issues:

Future Plans:

- More work on engine FX

- Tighter integration with Near Future Electrical

Recent Changes (0.1.0, historical changelogs are included in the download):

- Initial Release

Tech Tree:

This pack is compatible with the 2.1+ release of the Community Tech Tree. When this version is released, the mod parts will automatically be placed in the correct nodes (high-tier nuclear rocketry). These parts appear in the stock tree in a giant blob at Nuclear Propulsion

ABOUT THIS LISTING

This page describes Kerbal Atomics by Nertea_01. The description and screenshots are the author's own, imported from their listing on CurseForge on 25 October 2026: https://www.curseforge.com/kerbal/ksp-mods/kerbal-atomics

Mythiq.net hosts no files for it. The download button goes straight to the release file on edge.forgecdn.net, so you are downloading from the author's own host, not from a copy of ours.

The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

GAME VERSION

Built against KSP 1.12.5. Parts and plugins compiled for one major version routinely misbehave on another — a plugin for 1.8 can fail silently on 1.12.

DEPENDENCIES

Many part packs and plugins depend on ModuleManager, and some on each other. KSP's loading log (KSP.log in the game folder) names the missing dependency when a part does not appear; the author's page lists the usual set.

1. Download the archive with the button on this page and unzip it.

2. Move the mod's folder — the one containing the .version file or the part folders — into:

Kerbal Space Program\GameData

The path in game must read GameData\\…, not GameData\\\…

3. Start the game. Parts appear in their categories in the VAB; plugins show their own toolbars or settings screens.

4. If the mod ships a CraftNote or extras folder, leave it — some packs store example ships and textures there.

UPDATING

Delete the old folder in GameData first. Two versions of one plugin loaded together is the usual cause of duplicate parts and toolbar errors.
