[1.12.x] Eris Launch and Orbital Services (ELOS) - Stockalike Gilmour Space Eris-1 | OFFICIAL KSP MOD

[Kion]

GILMOUR SPACE ERIS-1 [V1.0]

 

ELOS (Short for "Eris Launch and Orbital Services") is a KSP parts mod that provides all the parts you need to create Gilmour Space’s Eris-1 rocket in Kerbal Space Program.

Eris is a small 21-25m tall small sat launcher, which will be the first australian-made rocket, launching from Australian soil. It will deliver up to 305 kg to LEO, and its first flight is planned to take place ‘no earlier than’ the 15th of march 2025, from Gilmour’s own Bowen Orbital Spaceport near Queensland Australia.

This mod was created by Kion in collaboration with Gilmour Space in favor of celebrating their first orbital launch attempt, so we decided to make a little treat for the space community!

I wanted to try a different approach with this mod by making the textures look “stockalike”. I'm happy with how it turned out, and let me know if you like it down below.

And yes, not only is it a collaboration with Gilmour Space, but they also attributed this mod as the “official” Eris-1 KSP 1 mod.

Instructions:

How to Install ELOS:

• Download the mod from the respective official download links from both Github or SpaceDock
• Open the main .zip file, go inside the “GameData" folder, and locate the “ELOS - Gilmour Space Eris-1” folder and copy/drag and drop it onto your KSP directory GameData.
• For part variation, download the “B9 Part Switch” mod, along with its dependencies, and install it in the same way as previously.
• For more things like Custom Waterfall Plumes, download and install Waterfall along with its dependencies, and install it in the same way as previously. Then open the ELOS mod zip file and locate: “Extras > GameData > ELOS - Gilmour Space Eris-1” folder drag and drop the existing GameData folder to merge two together.

 

Craft File:

• Open the ELOS .zip file
• Locate: “Craft Files > Ships > VAB” folder
• Drag and drop the .craft into your custom save or existing generic Ships folder: For installation on to your KSP save: Locate your KSP save by going to: [Your KSP Directory]/saves/[Save Name]/Ships/VAB > And past the craft file. Or you can permanently install the craft file and be able to access it on all saves, by going to: [Your KSP Directory]/Ships/VAB > And past the craft file.

ELOS is licensed under the MIT license. In short, it's a short, permissive software license. Basically, you can do whatever you want as long as you include the original copyright and license notice in any copy of the software/source. There are many variations of this license in use.

 

Changelogs:

Spoiler

• Version 1.0 - First release, with all the parts to build Gilmour Space’s Eris-1 rocket.

 

Small Notes:

• The size of the vehicle, tank propellant quantities, and engine max thrust values are not accurate compared to real life since it's made to roughly match other stock-like part mods out there, but may not be fully accurate (This is something with feedback from users I hope to fix if it needs to).
• The models made for this mod are not fully accurate, but maybe after the first attempt of Eris, I will get together with Gilmour Space (once they have the time) and refine the models with better references.

I'm having trouble getting the mod to work. Any tips? I'm following all instructions but the parts don't show up in game. Are there any conflicting mods?

Have you also copied the folder "ELOS - Gilmour Space Eris-1" into GameData or what does it look like?
Did you download it from Spacedock or github? Because:

@Kion

Your download via github does not work as it only contains the license and the readme.

If you want to download the mod from GitHub, go to the releases tab and choose the latest one.

Not sure. Could you provide a bit more context or provide some screenshots?

Yeah, so looks like you did not un-zip the mod. Read and follow the instructions provided to install the mod correctly.
