Quote by Joe William Gensler

“First consider the human systems and mission objectives when planning human space exploration. Understand what the mission is trying to accomplish and the duration. Design from the inside-out! Select the suits, cockpit/seats, EVA equipment and rovers, airlock, crew survival equipment, ECLSS, non-toxic fluids/gases/materials, crew quarters/hygiene systems, exercise equipment, water/air/waste recycling, quantity of food/water/oxygen, radiation protection, power source; then back out the spacecraft and launch vehicle that fit the items with +15% mass margin +10% volume margin. Dominant minds have prevailed in past space exploration architectures where a launch vehicle and spacecraft were proudly chosen prematurely, then when reality sets in; the same minds complain too much mass, too little volume, too high cost, and too long a schedule exist to fit their vehicles!”
