📦 Astronaut Crew Consumables Planner

📦 Astronaut Crew Consumables Planner

Turn crew size and mission duration into a first-pass launch mass for water, food, oxygen and daily supplies. Every per-person assumption is editable, including water recovery and contingency.

Editable daily assumptions · kg per person-day

Planning arithmetic only, not a flight-certified life-support model. Rates vary with vehicle, menu, workload, recovery hardware, leakage and mission rules; use programme-controlled values for real operations.
