1. What is the vessel classification?Hypothetical interstellar ark starship or world ship
2. What is the propulsion paradigm?Operates at sub-light velocities, necessitating multi-generational travel
3. Why do we need a generation ship for space travel?Because traveling to other stars takes many hundreds or thousands of years, so the original crew would not reach the destination; their children and grandchildren would.
4. How does a generation ship keep people alive for so long?It has a closed‑loop life support system that recycles air, water, and waste, and grows food with hydroponics or other indoor farming.

World Ship: A massive spacecraft designed to serve as a self-contained, mobile habitat for an entire population over extended periods.
Sub-light Velocity: Travel at speeds less than the speed of light, the universal speed limit.
Closed-Loop Ecosystem: An artificial environment where resources like air, water, and waste are continuously recycled and reused.
