Preamble by MatterBeam

After testing out Extraplanetary Launchpads and Roverdude's MK/OKS, MatterBeam had the idea of creating a simple, user friendly mod that would allow you to build rockets without taking a 200MB hit to RAM or having to juggle multitudes of resource pathways. If you know how to set up a drill, ISRU and a fuel tank for an Ore to Fuel conversion, then you should know how to build rockets.


  • No extra parts
  • No RAM usage
  • Added functionality for the Mobile Processing Lab in the late game
  • Simple, configurable and adds levels of depth to the gameplay without a learning curve
  • Ore --> Metal --> RocketParts --> rockets!

Cabin notes by zer0Kerbal

  • Will remain prerelease until taniwha releases Extraplanetary Launchpads as release instead of alpha/beta/prerelease and so new prereleases ONLY available on CurseForge
  • I have not personally tested the patches
  • Known issue(s)
  • If the offset/rotation gizmo's are used on the docking ports, the spawn location might be off. This is a known issue and a feature request has been sent to taniwha
  • Kerbalism compatibility is considered EXPERIMENTAL.
  • certain builds may require no RocketParts and time to complete. We are aware of this and any assistance with this issue would be appreciated.
  • most images/shields are also links.
