Methodology

Every mission, the 8 SMAD phases, auto-seeded

New aerospace missions are auto-seeded with the 8-phase SMAD lifecycle — Concept, Environment, Orbit Design, Spacecraft Design, Requirements & V&V, Launch, Operations, Closeout — plus 104 gate criteria drawn from NASA NPR 7120.5, NASA SE Handbook (SP-2016-6105), and ECSS-M-ST-10C. 100+ calculators: orbit mechanics, spacecraft sizing (ADCS, EPS, thermal, RF, propulsion), cislunar design, high-fidelity propagation, and AI trajectory optimization.
