Micdoodlecore 1.8.9/1.7.10 (library for galacticraft mod)

Step Six: Building a Rocket

Reviewing steps completed so far: you’ve gathered ore and oil, created a power source (perhaps even solar power), crafted various machines for processing ore and filling both fuel and oxygen tanks, you’re wearing your spacesuit gear — or at least the oxygen-related components — since it’s always a good idea when leaving solid ground to carry a Parachute, add that too. The last slot on the spacesuit tab is for a Frequency Module — it’s optional, but will help you hear sounds properly while in space (it’s also used with the Telemetry Unit so that your buddies can keep track on you from your base, if you are playing with friends).

Every space program of course needs a rocket. It’s now time to get to work on that. First up, build the NASA Workbench — right click to view the Tier 1 Rocket layout. Insert the various components to make the rocket — nose cone, plating, fins and of course, the engine. Pro Tip: wooden chests are optional, but not expensive, so you should always add 3 wooden chests when crafting your rocket to give it the maximum cargo hold.

Build a launch pad and place your rocket on it and you’re almost ready for take-off!

Installing a Fuel Loader next to the launch pad enables the loading of fuel via canisters made in your Refinery. Other mods can also enable piping fuel directly, rather than using canisters. Click the Load Fuel button to start the fuelling process for your rocket. Enter your rocket and press «F» to not only view the fuel load percentage but also your inventory and — if you added chests during assembly — the inventory of the rocket itself.

Geological Features


Mars terrain (true color).

Mars topography (the brighter, the higher).

The surface of Mars is riddled with craters, tall hills and deep valleys and its height may vary sharply from y=50 to y=140. It is covered by Mars Surface Rock and, underneath it, Mars Sub-Surface Rock. The martian soil is completely sterile, unless you use a Terraformer to convert it into cultivable soil.

In Galacticraft 3 and Galacticraft 4 there are rare patches of Ice under the surface.


The planet’s underground features include caves like those of the Overworld’s and also huge sludge-flooded caverns which are large and tall circular rooms underground, where poisonous plants, the Cavernous Vines, grow from the ceiling and the floor is mostly flooded with Bacterial Sludge.

Tin, copper, iron and Desh ores can be found on Mars. Desh is an important ingredient for some of the more advanced blocks and items in Galacticraft! And Desh armor gives very solid tank-like protection, including reduced knockbacks.

Naturally generated lava and water pools do not exist on Mars.

Silicon compatibility with other mods

Galacticraft consumes a lot of silicon, it’s needed in the Circuit Fabricator. Silicon Ore is hard to find, but if you mine it with a Fortune III pick you can get plenty of silicon from a good mining expedition.

Galacticraft 3 offers compatibility with other mods’ versions of silicon — for example, EnderIO can extract small amounts of silicon out of sand or clay, using the SAG Mill. If silicon from other mods is in the Ore Dictionary, then Galacticraft’s Circuit Fabricator can use it. But you have to set in Galacticraft’s core config what the OreDict name of the silicon in the other mod is, because there are a few different names can be used. The default is which is used by EnderIO and several other mods. Other tech mods — for example MineChem or GregTech — may have different versions, with different OreDict names like «plateSilicon», which are harder to make but maybe more suitable for Galacticraft as more of an end-game mod.

To disable Galacticraft from being able to use other mods’ silicon, just change «itemSilicon» in Galacticraft’s config to a word which can’t be in the Ore Dictionary, like your cat’s name.

If you want to make for a very hard game, you can even disable Galacticraft Silicon Ore from generating in the world, so there will be no Galacticraft silicon. If you then set an advanced item from some other mod as the OreDict name of silicon which Galacticraft must use, that could make it so even something as simple as a Galacticraft solar panel is a very late game item.

Galacticraft 4: Compatibility notes

Galacticraft 4 is currently compatible with most other mods. For extra notes about Sponge compatibility on servers, see Sponge.

If you come across compatibility issues, please (1) check the latest Galacticraft version as we make compatibility improvements all the time; (2) if there’s still a problem in the latest, let us know on Github. Also try installing PlayerAPI mod, that can fix some compatibility issues. (The compatibility notes for Galacticraft 3, below, may also be relevant.)

Player inventory tabs

Custom NPCs In Minecraft 1.10.2 and 1.11.2, please make sure to use the latest (25 May 2017 or later) version of this mod with Galacticraft, older versions had inventory tab overlapping issues.

More Player Models In Minecraft 1.10.2 and 1.11.2, please make sure to use the latest (25 May 2017 or later) version of this mod with Galacticraft, older versions had inventory tab overlapping issues.

TechGuns uses its own inventory tabs which overlap with ours — if this is affecting you, please ask the TechGuns developer to update and use our API for compatibility.

Fixed compatibility issues

Avaritia Infinity Armor and other mods with custom hi-poly armor — please update to Galacticraft 4 build 152 or later, to have the armor drawn correctly on planets

Finder Compass To prevent client disconnects, please update your Galacticraft 4 to build or newer.

JourneyMap If you are using JourneyMap waypoint teleports to travel between different planets, please update your Galacticraft 4 to build or newer.

Forge — mods missing screen If you get a crash with this type of error when you start the game: (Minecraft 1.10.2 might show instead of there) it might be Forge trying to give you that brown screen naming the required mods «missing», but crashing instead of showing the screen. To solve this issue, try updating Galacticraft and MicdoodleCore to the latest version.

Known compatibility issues

All Shaders mods — please switch off shaders when you leave the Overworld and travel to other planets — shaders mods cannot understand the dark or differently colored sky on the Moon and other planets.

Advanced Rocketry is a space-themed mod which has made some overlapping content with Galacticraft. If Advanced Rocketry and Galacticraft are installed together, Advanced Rocketry may take over some of the space dimensions, for example you may have some features of Advanced Rocketry’s oxygen system or gravity on the Moon instead of Galacticraft’s features on the Moon. For example, players have complained they can’t breath on the Moon when they are wearing Oxygen Mask, Oxygen Gear and full Oxygen Tanks — if you’re wearing those then it’s Advanced Rocketry which is stopping you breathing, not us. We are hoping the Advanced Rocketry guys will provide a config or other solution to avoid this conflict (like they did in the 1.7.10 version of their mod)

WAILA: some versions of WAILA have a bug where the color of grass, leaves, sand and some other blocks changes to grey when the player is mounted in a vehicle, including a Galacticraft rocket. If using WAWLA with WAILA, please make sure to use the latest Galacticraft version.

Cubic Chunks mod causes multiple weird issues with Galacticraft if you build outside the 0-255 height range — for example it can interfere with rocket launch and landing.

ViveCraft is compatible with Galacticraft, but it needs you to set a config setting: «Disable Vehicle Third-Person and Zoom»=true

Minor issues reported with PlayerRevive and Valkyrie Warfare mods.

Custom NPCS has been known to cause issues when loading a modpack with Galactacraft 4

Step Three: Crafting Machines

Galacticraft has quite a number of machines — usually the size of a crafting table — that perform some amazing functions. This part of the tutorial covers the basic machines you need to start off with.

Although the orientation of a simple crafting table doesn’t matter much, the machines you create using Galacticraft have some unique sides to them. Some might require power input on a particular side, some might produce oxygen on another side, and so on. Many of the machines need electricity to power up, though a couple of them are powered using coal.

Like regular Furnaces and Crafting Tables, usually right-clicking on the machine will let you view its console. Moving your mouse over the slots in the machine’s console will give you some information about what each part does, and what materials go where.

Circuit Fabricator

The first machine that you will want to build is the Circuit Fabricator, since it creates the Basic Wafer and Advanced Wafer which are essential components used in many of the other machines. (It also creates Solar Panels which you will use later to make solar power.)

Side Note (Galacticraft 2 only): If you power a Circuit Fabricator via a Buildcraft kinesis pipe network, we recommend using an iron kinesis pipe to limit the power that it draws. It works fine on an iron pipe at the lowest 2 MJ setting, but connected directly to a high-power pipe network, it can draw all available power.


Now that you are able to create a Basic Wafer, the next machine to build is a Compressor, which compacts ingots into more durable, compressed versions of the material. The Compressor runs on coal, or other combustibles. Later you will be able to make an Electric Compressor that runs from a power source instead, but since it requires compressed materials to build, you need to make the coal-fired one first.


Standard Space Station with Sealing Station

To create a space station, fly your Tier 1 or Tier 2 Rocket to space. You will then be given the option to create a space station in the Planet Selection Screen so long as you have the required materials in your inventory (required materials listed below).

The components below will assemble a basic space station comprised of a small main room with the roof and corners built, a platform where you can place a Rocket Launch Pad, and a Parachest containing your rocket and a small amount of left-over fuel that can be collected using an Empty Liquid Canister. The station does not have any sort of oxygen or other life support so you should prepare accordingly.

Some recommended supplies include:

  • Oxygen Mask, Oxygen Gear, and Oxygen Tanks
  • Food and Building Materials
  • Oxygen Collectors, Oxygen Distributors, and Oxygen Compressors
  • Trees, wheat, or other source to collect oxygen from

It is recommended that you read the oxygen tutorial.

Once you have the materials, grab your rocket and launch into space! Once the Planet Selection GUI shows up, select the «Create Space Station» button at the top of the screen. There should be a new option in the Planet Selection GUI with «Space Station» in its name (you may also rename your space station on this screen after it has been created). Select it and hit the «Go to Dimension» button to go to your Space Station.

After you have made the Space Station you may want to add some Oxygen Sealers and Oxygen Distributors and some Air Locks.

Galacticraft 1

If you are still using the old Galacticraft, the materials required to create a space station depend on the prerequisite mod you installed, either IndustrialCraft 2, Thermal Expansion or Basic Components.



Slimelings are tameable mobs found on Mars. Slimeling Eggs have a chance to spawn on the surface of Mars. They can be red, blue or yellow. They can be renamed and fed to create mini-slime bodyguards.


Sludgelings are some kind of macro-bacteria that spawn in swarms in the Bacterial Sludge. They attack any mob, including the players. A Sludgeling swarm takes place when any mob touches or gets close enough to the bacterial sludge.


The Mars boss is the Evolved Creeper Boss, which can be found in the Mars dungeons. The boss is a three-headed giant Creeper that has an Oxygen Mask and shoots TNT at the player on sight.

What Next?

There are tons of great things you can try out in Galacticraft, and more are being added all the time!

Here’s a short list of things to try out:

  • Construct an Overworld Space Station and invite your friends.
  • Explore the Moon and make contact with a colony of Moon Villagers.
  • Make your mark, by placing a Flag on the Moon or try it on the Overworld.
  • Mine up some Cheese Ore.
  • Establish an oxygen supply system on your Space Station, or Moon Colony.
  • Make a Moon Buggy and drive around in it.
  • Mine some Meteoric Iron and build Spin Thrusters to have your Space Station spin
  • Build a more technological looking base, with Arc Lamps for illumination (this is the brightest light source available in Minecraft) and Display Screens on the walls
  • Continue on to Mars.
  • Mars unlocks a new material, Desh which will let you make better armour and tools and some other more powerful items
  • Mars also unlocks new machines, and access to the Asteroids …

This How To guide can give you some more ideas for what is truly possible in Galacticraft…

Commands available to all players


/gcenergyunits <unit> — changes the units used by Galacticraft to show how much energy something has or uses. The available units will depend on which other mods you have installed. Possible choices are:

  • gJ (Galacticraft Joules)
  • RF (Redstone Flux)
  • EU (EU — only if IC2 is installed)
  • MJ (Minecraft Joules — only if BuildCraft or EnderIO 2.0 is installed)
  • J (Mekanism Joules — only if Mekanism is installed)


/gchouston — available in Galacticraft 4 only — rescues a player who is stuck on the Moon, or another planet or space dimension. It teleports the player back home to his bed on the Overworld (or to Overworld spawn if the player currently has no bed). Of course this is a one-way transfer, the player would need to build another rocket on the Overworld to return to space. The command must be typed twice to confirm that the player really wants to do this. (12 second timer)

If the game detects that a player is in a dying loop on the Moon or another planet, it will prompt for this command in chat. The player does not have to use the command but he can choose — if he uses it, there can be a chat sequence like this.

Uh, Houston, we've had a problem.... (Type /gchouston to abandon mission and return home.)
This is Mission Control, say again please? (To abandon mission, type /gchouston again to confirm.)
OK, stand by, <name>, teleporting to Overworld home position.

Energy Units

In Galacticraft 3, the energy system has been re-balanced and a new energy unit, the Galacticraft Joule (gJ) is used. A typical basic machine uses 600 gJ every second — less for low power machines like the Oxygen Sealer, more for high power machines like the Electric Furnace. A machine’s energy usage is shown on a tooltip if you have the machine in your inventory. An Energy Storage Module stores 500,000 gJ, enough to operate one basic machine continuously for around 13 minutes.

In Galacticraft 3, the player can use the command to switch in-game displays for Galacticraft machines to any different energy units preferred. The available list includes:

  • MJ from Buildcraft
  • EU from IC2
  • Joules (J) from Mekanism
  • Redstone Flux (RF).

Galacticraft 3 is a 100% RF-compatible mod, and has been compatible with RF since the beta phase of Galacticraft 3 . What does this mean? Although the inner workings of Galacticraft do not use RF, Galacticraft will use RF when connecting its machines or wires to any of the CoFH mods or any other RF mod. Note: RF and CoFH mods can sometimes be pretty difficult to install and set up, due to coremod and API updates between their different versions and not much in the way of documentation. Whatever, Galacticraft works with all of them without any problem!!! But because of these setup issues, it’s worth bearing in mind that Galacticraft does not need RF mods and there are alternative power systems, for example Mekanism.

Because Galacticraft is compatible with everything, some players use Aluminum Wire to convert power between IC2 / Mekanism / RF. That’s OK with us.

Galacticraft 2 and previous versions

In original Galacticraft and Galacticraft 2, the energy units are kiloWatts (kW) and kiloJoules (kJ). A typical basic machine uses 4 kW to operate, that’s 4 kJ every second. An Energy Storage Module stores 2.5 MJ, that’s 2500 kJ, enough to operate one basic machine continuously for around 10 minutes. Those kW and kJ units were the equivalent of the Watts and Joules units used in Mekanism and in the Universal Electricity mods, so 1 kJ in Galacticraft was 1000 J in Mekanism.

Early versions of Galacticraft 1 were part of the Universal Electricity system. That was a neat idea to have a lot of different mods by different authors all use one energy system. Sadly good intentions do not always work out due to people having differences of opinion. By the time of Galacticraft 2, Galacticraft left the Universal Electricity stable and created its own internal energy system. That started out being fairly similar to Universal Electricity, but was developed and improved through Galacticraft 2 updates. Major performance improvements were made at that time.

Galacticraft 3 uses an updated system which is more compatible, more stable, higher performance, and also offers 2 tiers of electrical machinery and the ability to transmit electricity using beams.

Liquid Oxygen

Liquid Oxygen is a cryogenic (extremely cold) liquid form of . It is a useful way of transporting Oxygen in a compact form. It can be transported in special canisters, or in fluid pipes from other mods. It is not intended that it can be transported in buckets!

If Liquid Oxygen is placed in a normal oxygen-using machine like an Oxygen Sealer or Oxygen Storage Module, the liquefied oxygen turns back into a gas. 1 bucket (1000 mB) of Liquid Oxygen can make 5,555 units of .

Using the Liquid Oxygen Canister, Liquid Oxygen can also be used to refill player oxygen tanks in an emergency.


  • In real life, Liquid Oxygen is transported in special flasks used for handling super-cold liquids.
  • At -183 °C it will be a constantly boiling liquid, whenever exposed to normal room temperatures. It boils rapidly because, to the Liquid Oxygen, room temperature (25 °C) is a very hot temperature, well above its boiling point. When it boils it becomes oxygen gas.
  • Because it is pure oxygen, Liquid Oxygen is extremely dangerous used near to any sparks or naked flames: any flammable object will burn almost instantly in pure oxygen (especially if it is dunked in liquid oxygen!)
  • In the aeronautics and space industries, Liquid Oxygen is often known as LOX

Full Guide

Before we begin: Mod Compatibility Notes

Some quick points that you will be interested in if you are using Galacticraft in conjunction with other mods. For full notes on compatibility see Compatibility.

Power Sources

Some Galacticraft machines need power to function. This can be provided in the form of:

  • Galacticraft energy (from the Coal Generator, Basic Solar Panel, or Advanced Solar Panel)
  • RF (Redstone Flux) (requires Thermal Expansion in Galacticraft 2 — Galacticraft 3 and Galacticraft 4 work with all RF mods)
  • Mekanism J (Joules)
  • IC2 EU (Energy Units)
  • Buildcraft MJ (Minecraft Joules)
  • Universal Electricity’s UE units (Galacticraft 1 only)

Ore Dictionary

Galacticraft’s ores and fluids are registered with the ore dictionary, thus making them compatible with most other mods. For example, Galacticraft Copper Ingots and Tin Ingots are interchangeable with: Mekanism, IC2, Tinker’s Construct, Thermal Expansion or Forestry copper and tin. Galacticraft Oil and Rocket Fuel are interchangeable with Buildcraft oil and fuel. EnderIO Rocket Fuel Buckets can also be used in your Fuel Loader.

Aluminum Ore can be powdered in Thermal Expansion’s Pulverizer. From version 139 (February 2018), Galacticraft 4 also lets Aluminum Ore be ground in a Grindstone from Applied Energistics 2 or it can be macerated in an IC2 Macerator (and then processed further in IC2 by ore washing and thermal centrifuge).

Non-fixable issues

These will need to be fixed by the authors of the other mods.

More Player Models

We cannot offer compatibility with this mod, as it uses an approach which is not really compatible with other mods. You may have improved results if you install Player API and Render Player API, try it and see.

Too Much Time

This mod’s dimension handling will cause crashes whenever you travel to a Galacticraft dimension, so basically Galacticraft is unplayable if you have Too Much Time installed.

Shaders Mod

Karyonix GLSL Shaders Mod is currently unsupported; the sky will not look good on Galacticraft planets or space environments. Best would be if that mod can auto-disable itself in Galacticraft dimensions.

Moon Base

For a longer stay on the Moon, apart from the Fuel Loader and Empty Canister (needed to refuel your rocket to come home again), the items you should be taking to the Moon with you might include:

  • power source — solar panels, wires and Energy Storage Module
  • oxygen source — Oxygen Compressor, some dirt and seeds or saplings, or a couple of stacks of leaves
  • a source of light
  • food(!)
  • Oxygen Bubble Distributor or Oxygen Sealer and some Oxygen Pipes

You might also want a couple of water buckets to make a water supply, although water can sometimes be found in Alien Villages.

If you are wondering what the Sealer’s, Collector’s and Bubble Distributor’s function and purposes are, oxygen can be provided to your Moon-base through the use of the Oxygen Collector. Breathable oxygen is created by planting two or more trees on the moon with a source of water nearby with the Oxygen Collector very close to the leaves of the trees. Then, connect the Oxygen Bubble Distributor to the Oxygen Collector with Oxygen Pipes, so that the oxygen can travel from the collector to the Bubble Distributor. The Bubble Distributor is meant as a quick way to get you started, so you can take your mask off. For a more permanent base you will probably want to build an Oxygen Sealer which can fill any enclosed space with oxygen. To «enclose» your future Moon-base, it’s just a case of making sure that the walls are solid, and you will need a door made of solid blocks. If you are good with redstone, you can perhaps make a piston door, otherwise Galacticraft has Air Locks. To make one of these you will need at least seven Air Lock Frames, and one Air Lock Controller — note that has Meteoric Iron in its recipe so it can’t be made until you get to the Moon.

Like all Galacticraft machines, the oxygen providing machines require a source of power to work. A good source of power on the Moon is the solar panel, so long as you have a couple of Energy Storage Modules to keep everything running during the long Lunar night. A Coal Generator might be good to have as a backup.

Can you live permanently on the Moon?

The short answer is yes, as long as you took some supplies with you for farming food — so some wheat seeds, and maybe some pumpkin seeds, cane, and chicken eggs (to make a chicken farm, and eventually pumpkin pie). You will also need saplings to grow trees (needed to make enough oxygen for the Oxygen Collector) and as a supply of wood — or you can maybe steal saplings from an Alien Village.

There are some mineral resources on the Moon: so you can gather plenty of copper ore and tin ore, and Meteoric Iron which is an important resource to build some of the more advanced mid-game items, and to get to Mars.

However, some materials are lacking on the Moon and can only be found on the Overworld. These include: iron ore, silicon, gold ore, lapis lazuli, redstone, diamonds, lava and obsidian. Maybe also ores from other mods (depending on your ). Also cobblestone, gravel, sand, flint and dirt! All are suddenly precious commodities on the Moon, as you will only have what you brought with you. To replenish supplies of these materials, and perhaps also for food or other items, you will probably need to return to the Overworld sometimes — at least until you reach Mars, after that you can maybe set up an automatic system of Cargo Rockets and loaders and unloaders to bring you the items you need.

There are mobs on the Moon (Evolved Creeper, Evolved Zombie, Evolved Spider, Evolved Skeleton) and also (in Galacticraft 4 Evolved Endermen, so you can find Ender Pearls on the Moon.

It is impossible to reach The End from the Moon, and it is hard to reach the Nether as a Nether portal cannot be ignited in a no-oxygen environment. (Future versions of Galacticraft may disable Nether portals totally in space dimensions.)

There are no animals on the moon, and you cannot carry living animals with you in a rocket (unless you have another mod giving you a way to transport animals). This means normally in Galacticraft the only animals you can have on the Moon with you are chickens, because you can at least carry eggs.
