SpaceY Expanded (SYX))

Forward by NecroBones

This parts pack is an expansion for the SpaceY Lifters (SYL) pack and requires that one as a dependency.

The name is a play on "SpaceX" in the real world, but also has the amusing double connotations of being "spacey", and also "Space, why?" -- Because it's there!

We hope you enjoy this pack. If you have any comments or feedbacplease feel free to send a private message to ~~NecroBones~~ zer0Kerbal on the forums. Thanks!

Part of the NecroBones suite of mods, that work nicely together!

Design Goals

  • Provide some new visual styles, to dress up the booster sections of your rockets.
  • Help mildly reduce part count and wobble, by providing larger tanks.
  • Be as memory efficient as possible.
  • Each diameter has a shared texture to keep memory usage low.
  • Follow the same colors and artistic style established in Color Coded Canisters.


  1. Note that the stats, appearances, and descriptions of the parts shown below are subject to change, or may be out of date.
  2. The "Delta IV Heavy" shown in some screenshots below includes parts from several other mods.
