Knowra Space colonization Space colonization Space colonization is the establishment of permanent or long-term human settlements beyond Earth, including settlements on other worlds and in artificial habitats.
Life support system : A system that supplies breathable air, drinkable water, food, and other conditions needed to sustain human life. Settlements must maintain these essentials where Earth’s atmosphere and ecosystems are absent.
Lunar settlement : A permanent or long-term human settlement on the Moon. The Moon is a nearby destination for testing sustained settlement beyond Earth.
Outer Space Treaty : The 1967 international treaty that establishes principles governing states’ activities in outer space. Its rules constrain national claims and shape legal arrangements for settlements.
Space exploration : The investigation of space through observation, robotic missions, and human activity. Exploration can occur without the permanent presence that defines colonization.
Space colonization feasibility : The assessment of whether permanent human settlements beyond Earth can be built and sustained. It brings together unresolved engineering, economic, and biological constraints.
In-situ resource utilization : The use of materials found at a destination to support exploration or settlement there. Using local ice, soil, or minerals could reduce the supplies settlers must bring from Earth.
Mars colonization : The establishment of permanent human settlements on Mars. Mars is a leading planetary destination in plans for settlements beyond Earth.
Space law : The body of international and national law governing activities in outer space. Settlement depends on legal rules for jurisdiction, safety, and resource use.
Spaceflight : Travel beyond Earth’s atmosphere or through outer space. Transportation is necessary for settlement but does not itself establish one.
Artificial gravity : The creation of gravity-like effects in a spacecraft or habitat, usually through acceleration or rotation. Long-term health effects of low gravity make artificial gravity a consequential design question.
