Space Habitats: Living in Orbit Long-Term

Space habitats are large, artificial structures designed for humans to live in orbit.
Concepts like the O’Neill Cylinder envision rotating habitats that simulate gravity.
Rotation creates artificial gravity through centrifugal force.
Habitats would recycle air, water, and waste in closed-loop life support systems.
Solar panels could provide abundant renewable energy in orbit.
Designs include giant greenhouses for food production and oxygen.
Space habitats could host thousands, even millions, of residents.
They may serve as stepping stones for colonizing the Moon, Mars, and beyond.
Radiation shielding, likely using lunar regolith or water, is essential for safety.
Living in orbit could make humanity independent from Earth’s limited resources.
