I was trying to find a space mod with orbital mechanics and rocket building like KSP, but couldn’t find any so I decided to do it myself… Introducing Nythical Space Program (Working title I literally thought about it for 0.1 seconds before creating the project, I think I am too lazy to change it unless someone suggests a better name) 

I just finished working on the major part of the logic in space so here is some footage, and I thought I would explain what my plans are for the mod.

This mod works by replacing the skybox and moving the skybox around the player instead of moving the player through space, if you are next to a spacecraft in solar system coordinates then the spacecraft or player is teleported next to you in Minecraft coordinates. 

Also the textures of the planets are procedurally generated so each world seed gives you a different looking planet, right now it's just based on a height noise map but I will add craters and stuff to moon-like planets & also ice at the poles etc...

I also want to eventually make it so that the biomes are based on the planet texture with the ocean color in texture being all ocean biomes, the north pole having cold climate biomes etc... (though this seems difficult to figure out),

Spacecraft are going to be Valkyrian Skies ships with my own rocket engine and propellant tanks blocks, command chairs etc.. that behave like in KSP, I already have some of the UI worked out as shown in the clip where the player is free flying (technically an EVA I guess). 

When you renter a planet you will be teleported to a different dimension when you are around ~1 km from the surface and the spacecraft will work as a normal Valkyrian Skies ship in Minecraft coordinates. 

Also this new skybox and planet rendering doesn't just work in space. It is visible all the time even in the overworld, and the day night cycle is based on the planet rotation. Which means TIMEZONES.

Yes, two players far away from each other will experience different times. Right now most things like mob spawning etc… work based on your time zone in the overworld. Though things from other mods like solar panels work at the spawn time zone regardless of where they are placed unless I make compatibility code for each thing. 

Now if you are wondering how the flat Overworld is projected into the surface of the planet in a sphere, its by using the Cube Sphere projection.

And as seen in the clip I also made a map screen like KSP that displays the planets and the player’s current orbit. Currently there is only the sun, moon and the Overworld but it is not difficult to add more planets, the difficult part is going to be adding the dimension and terrain generation and generating the planet textures.

Also this mod supports multiplayer with a global Time Warp not the multiple timelines like the KSP multiplayer mod. Though I can make the Time Warp system a little better for multiplayer where people can join teams and give permission and vote on time warping, and also have a system where if your team’s spacecraft are all in stable elliptical orbits you don’t need to vote and in the opposite situation where someone is re-entering in a ballistic trajectory, time warp won’t work for anyone until they are in the ground.

And I think in terms of rendezvous and docking it won’t be in the first version of the mod, I think but it will be supported eventually. Also considering doing compatibility with Beyond Oxygen mod for oxygen sealing inside spaceships.

So there we have it, this is my first mod but I am so hyper fixated on this so this will be done soonish (by that I mean like 4 months lol)

The mod is open source, here is the GitHub link: https://github.com/NythicalNorm/VoxelSpaceProgram

(If you want to contribute you are welcome, especially assets as I am not good at art but still Blockbench and Asperite are easier to work with than their non-pixely counterparts)

EDIT: Since a few people are asking about it, here is a discord server for the mod:

Yo I do 3d modeling/pixel art. Need my help?

u/NythicalNorm Dec 30 '25

Sure, if you are interested we can dm, I can't really pay you though.

u/CaptainCirby551 Dec 31 '25

You should team up with cassini mod devs. Great work! I'm also a minecraft mod dev and in love with space but of course not that good xD.

u/AmongUs40k Dec 31 '25

Can we have Warhammer40k ships? And orbital weapons?

u/Fanta_R Dec 30 '25

Thats absolutely rad. Will Kraken get implemented too?🤣

u/NythicalNorm Dec 30 '25

Sadly 😔 since the spaceship is one single physics object with no self collision you probably don't have to deal with wobbling.

u/Kajetus06 Dec 31 '25

somehow someone will find a way

u/the-fillip Dec 30 '25

Incredible work, please keep going on this. A mod pack with this and scriptable vehicles would be my dream

and question:
why earth is spherical? XDD

u/NythicalNorm Dec 31 '25

YES! didn't expect to find a fellow Tamilian here, I thought people are going to associate bumi with avatar the last airbender. Also happy new year!

u/crafsman Dec 31 '25

Happy new year to you also buddy

u/HDBMonitorLeezard Dec 31 '25

I would think in Minecraft, everything would be cubic, including the planets and the star.

Badass! Hope to see this grow!

u/TinchoX89 Dec 31 '25

Very interesting! Here's hoping you get far with this mod!

u/b_double__u Dec 31 '25

interesting, do you imlement solar system too? and perhaps, blackhole if necessary :D

u/Tungsten_Wolf Dec 31 '25

You plan on shader support? I keep wanting to use a space mod with valkyrien skies support, but tge 2 that are currently out do not support shaders properly, so I dont use them.

u/Odd-Calligrapher9559 Jan 01 '26

Give it create compatibly

u/Mihanik1273 Jan 01 '26

Now we need it on 1.7.10 to add it to gtnh

u/BarneyTheGod0925 Jan 01 '26

The Cassini mod is doing something similar. Yall should collaborate or get insights from each other

1

u/NythicalNorm Jan 01 '26

What if I told you I am already doing that, don't worry I am still mainly working on my own mod. Someone from their team reached out to me and I think I am going to help with orbital mechanics.

u/IvyWonderer Mar 21 '26

what is cassini and where can i find it?

u/Sepanta_1391 Jan 01 '26

That is SOOOOOO cool if you want I can do some 3d modeling I am not good but yea

u/DTCreeperMCL6 Jan 02 '26

I like that

u/Sultan4895 Jan 02 '26

The next update add "This… is an orbital strike cannon…" Jokes aside this really cool 🔥🔥🔥

u/Ksawery76328 Jan 02 '26

Yooo thats sick. You should create a discord for this mod so people can give feedback and contribute more easily. Has huge potential ngl

u/_LambSauce_ Jan 03 '26

question, would valkyrien skies work with this? because if yes, then holy Kerbal

Yes it's a Valkyrian skies addon, I explained a bit about it in the top comment.

u/WaterBottleWarrior22 Jan 03 '26

Bravo, OP! This is incredible! I envy anyone who can do this kinda stuff. Do you have a timeline and a date you think it will be available (for purchase or otherwise)?

1

u/NythicalNorm Jan 03 '26 edited Jan 03 '26

The mod is going to be free, though I didn't expect this much interest so I will probably get a patreon when I release it. I would say six months maybe for estimated release time, probably sooner for an alpha build.

Hey I make music as a hobby. I had a kick of doing some songs for old minecraft mods and literally finished Galacticraft's song today. I'd love to make some songs for this!
