DO NOT DELETE
The primary focus for many players is to develop a colony which is suitable to their needs. Due to the randomness of planet types, finding suitable locations to build a colony can be challenging. This page will give you basic information to efficiently find useful locations for colonization.
These recommendations are based off my game experience, so if there are any concerns or clarifications needed in this wiki page, contact IdeoPraxist (in-game) or Prolapser (in-game or through Steam).
What is a colony?
A colony is a player-owned location outside of the inner 8 Apollo systems. Players can purchase a deed for the right to construct a colony on the surface of a planet or moon. Since there is no existing land mass (outside of the inner 8 systems) that has oxygen in the atmosphere, the only method for colonization is to build domes in a colony on the surface of a planet or moon. A deed can support thousands of domes.
The pictures below show a circular deed of the same colony. Each black dot on the surface of the planet is a dome. Domes can be placed anywhere in the deed in any formation.
Gathering resources is the primary reason for building colonies. Using the show mb.samplemapoverlay command of a probed planet, resource distribution is represented as colored rectangles. The picture below is the same colony as the pictures above.
For a colony to support domes, the surface of the planet or moon needs to be relatively flat. Mountainous and jagged surface will not support domes. Domes can be constructed in a liquid (under water or any large body of fluid), but currently it is not useful and not recommended. The best location for a colony is on a flat surface with no liquid.
These are examples of bad colony locations:
For first-time explorers, it is highly recommended that the location of their new colony is constructed on a planet or a moon with an an atmosphere, since colonies need gasses for domes to support human colonists. To determine if a planet or moon has an atmosphere, fly to View Range and look at the edges. If there is a "halo" effect around the edge, or if the planet has fluid, then it has an atmosphere. Not all atmospheric planets and moons have the halo effect, so some investigation may be needed.
Domes can gather gasses from the surrounding atmosphere and split components into useful gasses. The best distribution of gasses is an atmosphere that contains the elements Nitrogen (N), Oxygen (O), and Hydrogen (H) available in some form.
For example: CH4 can be split into Carbon and Hydrogen gas. NH3 can be split into Nitrogen and Hydrogen gas. H2O can be split into Hydrogen and Oxygen gas. CO2 can be split into Carbon and Oxygen gas.
Carbon (C) gas is currently useless and is vented from domes. Hydrogen, Nitrogen, and Oxygen can be contained as a gas in a dome or as a commodity resource which can be stored in a warehouse. Domes can combine Hydrogen and Oxygen to make H2O (water) and can also be stored in a warehouse.
Each dome needs at least 400,000 tons of gasses in its atmosphere. A class 12 ship can only carry 20,000 tons, so a colony with a planetary atmosphere is almost critical.
To see the gas contents of an atmosphere, fly down to the planet surface. You can take a gas reading by using the computer command: show rs.composition . If you receive the message "error, no medium", it means you are above the atmosphere or the planet does not have an atmosphere.
In the example below, this atmosphere reading demonstrates a good balance of needed gasses.
CH4 can be split for Hydrogen (for hyperdrive fuel), NH3 can be split for Nitrogen gas for domes and Hydrogen, and CO2 can be split for Oxygen for domes. There is even natural Nitrogen in the atmosphere. Any reading below 0.02 is non-existent on the planet or too little to be useful. Since domes need some water and there is none in the atmosphere, the dome can combine Oxygen and Hydrogen to form H2O.
To learn how to obtain soil samples, see Probing Tutorial.
Silicon and Geo
The two most important factors for evaluating a soil sample is the silicon percentage and the Geology rating (Geo). Your objective is to find a low silicon percentage and a high Geo score.
Silicon is not a useful resource and cannot be harvested from planets or moons. The higher the percentage of silicon, the lesser percentage of useful resources is available to your colony. The Geology (Geo) of the planet signifies the concentrations of the different resources. A Geo score of 1 (the lowest score) means the resources are distributed evenly throughout the planet, which is undesirable for a colony. A Geo score of 5 (the highest score) means that resources are concentrated in pockets and useful for colonies to harvest resources. You can see these pockets, represented as colored rectangles, when you use Core Sampling Probes to scan a planet and type into the computer: show mb.samplemapoverlay
Below are examples of soil analysis and sample maps of different planets with varying Geo scores and silicon percentages. The brighter/lighter the rectangle, the better resource concentrations.
Geo 5 planet with low silicon (no fertility)
Geo 5 planet with moderate silicon (all fertility)
Geo 3 planet with low silicon (one fertility)
Geo 5 planet with 92% silicon
Geo 1 planet with 72% iron (low silicon)
To make a star system more appealing, you may want to consider the following factors in picking your new colony.
Light Year Distance from a Repair Facility
If your colony is farther than 100 light years from a repair facility, your HyderDrive may become damaged and cannot be used again without a repair facility. In this case, if you want to move star systems, you would need to use 'Emergency Jump!' in the Map to return to Ceres in the inner-8 systems to repair.
A slow-moving, quick-respawning asteroid belt with a high concentration of Columbine, Argite, and Autunite asteroids would be highly desirable in a star system since these asteroids provide Niobium, Tin, Magnesium, Uranium, and Silicon. A well-balanced colony and this type of asteroid belt will give you access to all the mineral resources currently available in the game.
In future game updates, there may be the need to scoop unique gasses which can only be found in gas giants. A few multi-colored gas giants might be useful to have in a star system.
These recommendations are based on building a well-rounded colony. These values can be subjective depending on your colony objectives.
Any resources below these recommended numbers essentially does not exist on the planet in any useful capacity.
- "Smooth" land surface. Some hilly terrain can be colonized.
- Atmosphere: 5% of any gasses which contain Nitrogen (N) and Oxygen (O).
- Mineral Distribution: 7% for each useful mineral. Silicon should not exceed 55%.
- Mineral Concentration: Geo 2
- Smooth land surface.
- Atmosphere: At least 10% of any gasses which contain Nitrogen (N), Oxygen (O), and Hydrogen (H).
- Mineral Distribution: At least 12% for each mineral except Silicon.
- Mineral Concentration: Geo 4 or higher.
- At least one Fertile food type (Vegetable, Fruit, Animal, or Grain).
- Under 100 light years distance from a repair facility.
The Perfect Earth (rumoured to exist in this game universe)
- Earth-like planet with oceans of water (H2O). Smooth land surface covering >60% of the planet.
