Knowra Space settlement Space settlement A permanent human community established beyond Earth and designed to sustain its inhabitants. Unlike a temporary outpost, it must support ongoing life and social organization.
Life-support system : Technology that provides breathable air, potable water, suitable temperature, and waste management for people in enclosed environments. It supplies the basic conditions a settlement must maintain continuously.
Space colonization : The establishment of human presence beyond Earth, often framed as territorial expansion or large-scale migration. Settlement emphasizes durable communities, while colonization adds a contested political and historical framing.
Biosphere 2 : A research facility in Arizona that enclosed several ecological environments for experiments in biological and human systems. Its early experiments exposed difficulties in managing a complex, partly closed habitat.
Outer Space Treaty : The 1967 international treaty that establishes principles for state activity in outer space, including a ban on national appropriation of celestial bodies. Its rules constrain how states may claim territory or govern activities at settlements.
Closed ecological system : An ecosystem designed to recycle matter internally with minimal exchange across its boundaries. Recycling air, water, and nutrients could reduce a settlement’s dependence on Earth.
Lunar settlement : A permanent human community established on the Moon. The Moon offers nearby terrain and resources but no breathable atmosphere.
Mars Direct : A crewed Mars mission architecture proposed by Robert Zubrin and David Baker in 1990. It proposed producing return propellant from Martian resources before sending the crew.
Space law : The body of international and national law governing activities in outer space. It frames questions of jurisdiction, responsibility, and resource use beyond Earth.
Radiation protection : Methods for reducing exposure to ionizing radiation, including shielding, distance, and exposure-time limits. Beyond Earth’s protective atmosphere and magnetic field, radiation threatens long-term health.
Mars colonization : The proposed establishment of a lasting human presence on Mars. Mars is a prominent candidate for a settlement on a planetary surface.
