Luna
Luna is the first world past the station: grey, silent and slow. It is airless (bring a suit and oxygen), gravity is low, and a full day lasts about 28 Overworld days, with a hard line between light and dark. Nothing lives here until you make it live.
| Dimension | nerospace:luna |
| Rocket | Tier 1 or any higher tier |
| Gravity | 0.17 × Overworld |
| Day | 672 000 ticks (about 28 Overworld days, a little over nine hours of play) |
| Weather | None |
| Hazard | None besides the vacuum; you never need Rad Lining here |
| Villagers | None |
| Native life | Moon Hopper, on terraformed ground only |
Regions
| Region | What you find |
|---|---|
| Lunar Highlands | Regolith over bright Anorthosite; the most common region |
| Lunar Maria | Low, dark basins: a thin Regolith skin over Lunar Basalt; Helium-3 Pockets |
| Crater Field | Broken ground with Crater Glass pockets |
Below the surface everything is Lunar Basalt. Luna has its own terrain shape: its hills and valleys do not line up with the Overworld's.
Blocks
| Block | Tool | What makes it special |
|---|---|---|
| Regolith | Shovel | Walking on it leaves footprints that stay until the block is disturbed (a block placed on top, a piston, or walking back over it the other way). Landing on it kicks up dust. |
| Lunar Basalt | Stone pickaxe | The most blast-resistant stone in Nerospace. A block you place in Luna sunlight slowly sinters into Polished Lunar Basalt — no furnace, no fuel. Natural basalt never changes. |
| Polished Lunar Basalt | Stone pickaxe | Building block; from sintering or the stonecutter. |
| Anorthosite | Stone pickaxe | Bright rock. A full 3×3 of it directly under a solar panel gives that panel +25 %. |
| Crater Glass | Pickaxe (Silk Touch to keep it) | Translucent and sparkly. A light source touching Crater Glass shines one level brighter through it. It does not pass on light from further away, and two panes do not stack. |
| Ilmenite Ore | Iron pickaxe | Drops Raw Ilmenite (Fortune works). |
| Helium-3 Pocket | Iron pickaxe | Found in the Lunar Maria. Gives 2 Helium-3 Canisters if mined with Silk Touch or with a Gas Tank against it; otherwise half the gas leaks and you get 1. |
Nerosium and Nerosteel ore also generate on Luna. Something else is said to be hidden in the craters.
Items
- Raw Ilmenite: refined in the Fuel Refinery into a Titanium Ingot (plus oxygen). Titanium is the hull material for station modules and the Rad Lining.
- Helium-3 Canister: a late fuel additive for long trips.
Hazards and protection
Luna is airless, so you need an Oxygen Suit or a breathable zone. There is no heat, cold or harmful radiation, so a plain suit is enough and Rad Lining is never needed.
Clock and weather
A lunar day is 672 000 ticks. Late in the long night the Earth rises over the horizon and adds a faint earthshine; the HUD clock dial marks that stretch of the night and names it Earthrise. The night is visual: the sky darkens with the planet's clock, but block light, sky light and mob spawning work as before. Luna has no weather. See Planet Clock and Weather.
Beds work once the lunar night has fallen: when enough players on Luna are asleep, the clock jumps to sunrise (Earthrise is skipped if you sleep before it). A bed always sets your respawn point. See Sleeping.
Open water freezes. Luna is cold, so water under the open sky turns to ice like in a snowy Overworld biome, unless the block light at the water is 10 or more. Sugar cane planted by that water breaks when it freezes. Keep a light source within a few blocks of the water, or farm under a roof.
Sky
A black sky full of hard, steady stars in their natural colours (no twinkle: there is no air), with a faint band of the galaxy and a pale nebula veil. The sun is hard and white with a soft glow. Earth hangs over the eastern horizon with a blue atmospheric rim, a real day and night side, and city lights on the dark side; it rises around clock phase 0.78 (Earthrise) and its light brightens the horizon haze. Meteoroid flashes streak across the sky a few times a minute, day and night.
The full sky is drawn on NeoForge for Minecraft 26.3. On every other version Luna shows its colours with the vanilla sky shapes, and the world fog still follows the time of day and the weather.
Villagers and structures
None. Luna has no villagers and no settlements.
Terraforming and fauna
A Terraformer on Luna turns regolith into grey soil with lichen (Rooted), lets frost pools gather in the hollows (Hydrated) and finally settles a pressurised Lunar Meadow (Living). The Moon has no air to hold the change, so the edge of the meadow shimmers with a faint ring of light; step past it and you are back in vacuum. Terraformed ground on Luna seeds Ilmenite and Nerosium.
Living ground grows Luna's only native creature, the Moon Hopper: a small, quick grazer that hops on big hind legs. The Terraformer stocks the meadow with a starter group, and more spawn on Living ground. It drops a little Regolith and is never harmed by its home planet. See Creatures.
Star Guide
The Worlds: Luna chapter asks you to land, mine Ilmenite, build with Polished Lunar Basalt, stay out under the open sky through two minutes of the lunar night, and root your first terraformed ground.
Tips
- Lay Anorthosite under your first solar panels on Luna; the long lunar day already makes them strong, but the night is long too, so add a battery.
- Carry a Gas Tank when you go He-3 hunting.
- Luna is the source of titanium: bring Raw Ilmenite home before you plan station modules.
