Analyzed dynamics and control of orbits around asteroids modeled as uniformly rotating homogeneous rectangular parallelepipeds (HRP). Identified circular periodic orbits, studied stability of non-circular periodic orbits, and derived analytical lower limits for uncontrolled spacecraft orbital lifetimes.

• Developed spherical harmonics, polyhedron, and closed-form expression gravitational models to simulate the gravity field.
• Studied equilibrium points, stability against impact, and averaged SRP effects.
• Implemented fuel-efficient control techniques LQR and Sliding mode control techniques for station keeping.
