Space habitat engineering is understood through '''Circularity''' and '''Resilience'''.

'''1. The "Perfect" Circle (ECLSS)''':
Nothing is "Trash."
* On Earth, we have a "Massive Atmosphere" to "Absorb Waste."
* In a **Space Habitat**, every "Breath" and every "Drop of Urine" must be **"Reclaimed."**
* **CO2 Scubbers** "Pull" carbon from the air.
* **Water Processors** "Filter" "Sweat and Urine" into "Drinking Water."
* It is the "Ultimate" **"Sustainable Design"** (see Article 589).
* "Life" is a **"Closed-System Logic."**

'''2. The "Hard" Shell (Shielding)''':
The "Sun" is a "Monster."
* Outside Earth's "Magnetic Field," "Radiation" is "Lethal."
* To "Survive" on **Mars**, you might need to "Live Underground" or "Inside" **1 Meter of Water.**
* Habitats must be **"Built for the Environment"** (see Article 587), focusing on **"Mass as Protection."**
* It is "Living inside a Shield."

'''3. The "Biological" Anchor (Biophilia)''':
"Humans" are "Animals."
* (See Article 589). You can provide "Air" and "Water," but "Humans" will "Go Mad" without **"Greenery."**
* **Space Gardens** are not just for "Food"; they are for **"Sanity."**
* The "Smell of Earth" and the "Sight of a Leaf" are "Vitamins for the Mind."
* "Engineering" must "Include" "Biology" to be "Successful."

'''The 'International Space Station' (ISS)'''': The "First" "Global Habitat." It has been "Continuously Occupied" for **20+ years**. It proved that "Humanity" can "Build" a "Lifeboat in the Void," "Testing" all the "Systems" needed for the "Moon and Mars."
