Space mission analysts calculate trajectories, transfer orbits, station-keeping strategies, and mission phases using orbital mechanics, optimisation models, and high-fidelity simulations. They analyse mission constraints, launch windows, spacecraft dynamics, gravitational interactions, and mission risk. Their work supports deep-space missions, satellite constellations, planetary landers, and crewed spaceflight. They collaborate with spacecraft designers, navigation teams, and scientific mission groups. With increasing interplanetary missions and commercial launches, mission analysts are in very high global demand.
