5A Mars colony requires 4.2 liters of water per person per day. If the colony has 12 crew members and needs supplies for 150 days, how many cubic meters of water must be stored to account for a 10% contingency margin?

**5A Mars Colony Requires 4.2 Liters of Water Per Person Per Day. If the colony has 12 crew members and needs supplies for 150 days, how many cubic meters of water must be stored to account for a 10% contingency margin?** As humanity edges closer to permanent Martian habitation, one undeniable reality dominates conversations in space innovation circles: every breath, meal, and moment of survival on Mars hinges on managing the most vital resource—water. Current mission projections show a 5A Mars colony—designed for twelve crew members—requires 4.2 liters of water per person daily. Over 150 days, this totals a fundamental calculation: over 7,980 liters. Translating liters to cubic meters (where 1 cubic meter holds 1,000 liters), the base requirement comes to 7.98 cubic meters. But with operational risks, quality control, and long-term sustainability in mind, mission planners add a 10% buffer to safeguard against unforeseen losses—ensuring crew safety and mission integrity. --- **Why 5A Mars colony requires 4.2 liters of water per person per day.

This figure reflects real water usage intensity in deep-space habitats, where every drop is recycled, monitored, and carefully budgeted. The standard benchmark of 4.2 liters per person daily balances hydration, hygiene, and system efficiency. Multiplying 4.2
