Orbital Mechanics & Optimization Core

Implement the core orbital mechanics simulation and a multi-objective optimization algorithm to generate feasible OTV trajectories. Your optimizer should take an OTV's initial state and a list of target orbits for multiple payloads, and output a sequence of maneuvers (e.g., Hohmann transfers, plane changes) that minimizes fuel consumption while adhering to deployment windows and total mission duration. Explain your chosen optimization approach and how it handles constraints.
