Description
Cosmonautics: Planetary Expansion (AI assisted proyect)
Warning: this proyect is beta do a copy of your world before put this mod.
Create: Cosmonautics lets you build rockets and fly to the Moon. **Planetary Expansion gives you somewhere to land.**
Five new worlds, each with its own dimension, terrain, weather, dangers and rewards — and a reason to come back.
## The planets
**Mars** — Red dunes, canyons, highlands and polar caps. Meteorite craters with rare cores, half-buried ruins of old
missions, and **dust storms** that push you around and hit you with debris.
**Venus** — A scorching world of basalt plains, shield volcanoes and lava rivers. The heat wears down your armor and
**acid rain** falls from an amber sky. Rich in Create: Nuclear ores.
**Thalassa** — An ocean moon under a cracked shell of ice. Dive hundreds of meters into the dark: hydrothermal vents,
crystal geodes, glowing creatures… and something enormous passing in the distance.
**Ignis** — An airless volcanic world orbiting a gas giant: lava seas, ash plains and sulfur fields, under a sky full
of planets.
**The Ice World** — Eternal night, glaciers and crystal spires, with blizzards that freeze you to the bone.
## Planet suits and progression
Start with the **Basic Space Suit** (it works like the Cosmonautics gear: breathing, jetpack, thrusters, anchor boots).
Each planet hides the materials for an **upgrade template**: upgrade your suit at a smithing table into the
**Impact** (Mars), **Glacial** (Ice World), **Hazard** (Venus), **Sea Diver** (Thalassa) or **Thermal** (Ignis) suit.
Not ready yet? Craft **survival kits** (cooling gel, chemical heater, dust filter) for your first expedition.
## Creatures
- **Thalassa:** lantern fish, vent crabs that guard their chimneys, giant blue king crabs, and the eyeless
**abyssal stalker**, which hunts by sound.
- **Ignis:** lava-dwelling **magma snails** — and the rare **magma titan**, which spits fire if you anger it.
## Machines for your ship
- **Warp Drive + Navigation Console:** an end-game machine that jumps your ship to the orbit of any planet,
with a full-screen map of the solar system.
- **Gravity Generator:** normal gravity on board, powered by Create rotation.
- **Inertial Dampener:** a multiblock that stops your ship (or circularizes your orbit in space).
- Hologram table labels, windmills that spin faster in storms, beds that work in space (and on moving ships).
## Requirements
- Minecraft 1.21.1 · NeoForge
- Create (6.0+), Create: Cosmonautics, Sable
- Create: Nuclear and Create: Deep Seas (oxygen diffusers, sea pressure)
## FAQ
**Does it work in multiplayer?** Yes, it must be installed on both server and client.
**Can I add it to an existing world?** Yes. New planets generate when you first visit them.
**Shaders?** not at all but works.
