Life in a Space Colony, ep1: Extraterrestrial Colonies
Isaac Arthur・29 minutes read
Life on colonies or colonial spaceships is explored in the first episode of a series, emphasizing day-to-day living, governance, and key questions like purpose and size. Motivations of colonists, colony goals, and categorization of objects for colonization based on size and distance from the Sun shape life and access to resources, with colonies in different solar system regions requiring varying power sources and designs for sustainability and expansion.
Insights
- The purpose of a colony, whether scientific, economic, national, religious, or ideological, significantly influences day-to-day life and governance, shaping the functioning and goals of the colony.
- Objects for colonization are categorized based on size, distance from the Sun, and gravity levels, impacting self-sufficiency, resource availability, and the feasibility of creating colonies, with larger objects being more suitable for human habitation due to comfortable gravity levels and atmospheric stability.

What factors influence life on colonies in space?
Life on colonies in space is influenced by a variety of factors, including the colonists' motivations for settling, the purpose of the colony (scientific, economic, national, religious, ideological), the size and characteristics of the object being settled, and the overall goals of the colony. These factors shape governance, day-to-day life, and the methods used on the colony, such as terraforming or resource extraction. Additionally, the categorization of objects for colonization based on size, distance from the Sun, and proximity to other objects impacts self-sufficiency and resource availability. Gravity also plays a crucial role, with larger objects being more suitable for human habitation due to comfortable gravity levels and atmospheric stability.
How are objects in space categorized for colonization?
Objects in space are categorized for colonization based on their size, distance from the Sun, and proximity to other objects. Gravity is a crucial factor in categorization, with larger objects being more suitable for human habitation due to comfortable gravity levels and atmospheric stability. Objects are divided into categories ranging from category 0 (less than a kilometer across) to category 4 (lacking atmospheres but potentially having space elevators). The categorization influences the type of colonies that can be established, the methods used for transportation, and the level of self-sufficiency and resource availability.
What are the key questions for understanding a colony?
Understanding a colony involves considering key questions such as its purpose (scientific, economic, national, religious, ideological), founders, location relative to Earth and the Sun, size, and characteristics. The purpose of a colony can vary widely, with multiple goals often present. The size and characteristics of the object being settled influence the colony's ultimate goals and methods, such as terraforming or resource extraction. Additionally, the motivations and goals of the colonists, as well as the overall purpose of the colony, shape life on the colony and its functioning.
How do larger colonies differ from smaller ones?
Larger colonies offer increased specialization and self-sufficiency, with populations of at least a thousand supporting various professions like lawyers, surgeons, and veterinarians. Recruitment for specialized professions becomes easier with larger colonies, with a hundred people being the minimum for a viable colony and thousands more suitable for extrasolar colonies. Larger colonies also have the potential for vast expansion and specialization, allowing for a diverse range of professions and services to be available within the colony.
What are the challenges of colonizing deep space regions?
Colonizing deep space regions, such as those beyond the Kuiper Belt, presents significant challenges due to harsh conditions and limited resources. These regions require beamed energy or fusion power for colonization, as sunlight is scarce. The harsh conditions in deep space necessitate advanced technologies and infrastructure to support human habitation, making colonization in these areas more complex and resource-intensive compared to regions closer to the Sun.

"Life on Colonies: Motivations and Governance"
- The episode is the first of a series exploring life on colonies or colonial spaceships, focusing on day-to-day life rather than just technology.
- Reasons for avoiding this topic include varying colony life based on available technology, potential cyborg or genetically modified humans, and unknown behaviors due to unclear motivations.
- Day-to-day life and governance on colonies depend on the colonists' reasons for becoming colonists.
- Historical examples are used for insights into colonization motives, but modern parallels are also considered.
- Key questions for understanding a colony include its purpose, founders, location relative to Earth and Sun, size, and characteristics.
- The purpose of a colony can vary from scientific to economic, national, religious, or ideological, often with multiple goals.
- The size and characteristics of the object being settled influence the colony's ultimate goals and methods, such as terraforming or resource extraction.
- Colonists' motivations and goals, as well as the colony's overall purpose, shape life on the colony and its functioning.
- Objects for colonization are categorized by size, distance from the Sun, and proximity to other objects, affecting self-sufficiency and resource availability.
- Gravity plays a crucial role in categorizing objects for colonization, with larger objects being more suitable for human habitation due to comfortable gravity levels and atmospheric stability.

"Categorizing and Colonizing Objects in Space"
- Objects in space can be categorized based on size, with category 1 objects being 1-10 km in size, suitable for colonies the size of a mountain or metropolis.
- Even smaller objects, like category 0 objects less than a kilometer across, can support decent-sized communities that are self-sufficient.
- Category 4 objects mostly lack atmospheres but can potentially have space elevators and require minimal fuel for transportation.
- In the asteroid belt, there could be passenger planes or buses traveling between nearby asteroids, enabling individual asteroid homes or small villages.
- Asteroids can be moved closer to each other for easier access, allowing for shopping trips between colonies.
- Asteroids can be latched together using rigid metal shafts or long tethers, making it feasible to create megastructures or combine habitats.
- The solar system can be divided into five categories based on distance from the Sun: Inner, Middle, Outer, Deep, and Extrasolar regions.
- Inner regions, like Earth and Mars, offer abundant sunlight for plant growth and solar power, with fast communication.
- Middle regions, including Jupiter and its moons, have less sunlight but still viable for plant growth and solar power.
- Outer regions, beyond Saturn, require massive solar arrays or fusion power for colonization due to limited sunlight.
- Deep space regions, past the Kuiper Belt, are challenging for colonization due to harsh conditions, requiring beamed energy or fusion power.
- Colonies can be designed using rotating habitats, zero gravity environments, and parabolic dish setups for solar power, with the potential for vast expansion and specialization.
- Larger colonies are preferable for increased specialization and self-sufficiency, with a population of at least a thousand to support various professions like lawyers, surgeons, and veterinarians.
- Recruitment for specialized professions becomes easier with larger colonies, with a hundred people being the minimum for a viable colony and thousands more suitable for extrasolar colonies.

Future Colonies: Governance, Life, and Exploration
- Transhumans, with enhanced intelligence, can learn faster and live longer, potentially utilizing automation and artificial intelligence for mental work.
- Colonies in the solar system are likely to be under existing nations, possibly with autonomy and diplomatic representation agreements.
- Some colony members may stay on Earth, supporting the colony financially, while consulting firms and law firms back on Earth can assist with various issues.
- The type of government in colonies is uncertain and likely to vary, with different opinions on governance approaches.
- Day-to-day life in colonies will differ based on purpose, technology, and location, with future episodes exploring interstellar and interplanetary colony ships, crew concepts, and recruitment processes.
