This is really a collection of several mods written by Nehemiah (N3h3miah) which all have a common theme - orbital experiments.

Originally called "Orbital Material Science", the collection is really much more than that nowadays. The Spacedock release is a complete bundle, for individual component downloads please see the GitHub releases page.

There are 4 major components:

KRP - Kemini Research Program - Gemini-inspired in-capsule science experiments

Inspired by the Gemini program science experiments, these are for the early career mode play suitable for the Mk1 command pod.

KEES - Kerbal Environmental Effects Study - MIR-inspired out-of-capsule experiments

This set of experiments uses an external carrier (which must be attached in-orbit using KIS) onto which exposure experiments can be loaded (again using KIS). It is intended to be attached to a small orbital station with different experiments launched and installed over time.

Components can be brought to orbit using either a special carrier included in the mod, or standard KIS containers.

OSS - Orbital Station Science (WAS: KLS & OMS)

This set of experiments is the most ambitious, requiring various stages to complete and is intended for large, long-duration orbital complexes.

First, an orbital Lab must be launched. There are three labs, an MPL-600, MSL-1000, and MEP-825. Each lab (except for the MEP-825) needs to have lab equipment installed in it (which must be launched separately) before experiments can be installed and run. Lab equipment is specific to a lab, and experiments are specific to lab equipment - so ensure you have the correct equipment before launching experiments!

The Life Science experiments require one or more Kerbals on which the experiments are performed, so ensure you have enough victims on your station!

Each component can be downloaded and installed separately, or the entire collection can be downloaded as one mod.


The Forum Thread contains an in-depth overview and explanation of the mod, with screenshots!

Micha's Builds forum thread covers my maintenance builds of this mod while Nehemia is MIA.


KRP requires the ModuleManager mod.

KEES requires the KIS mod.

The remaining components are standalone, although may be enhanced by ModuleManager.
