A MATLAB script for Earth-to-Mars Mission Design - SNOPT

Design and optimize end-to-end Earth-to-Mars ballistic trajectories from Earth park orbit to Mars B-plane encounter.

PDF document and a MATLAB script named e2m_matlab_snopt.m that can be used to design and optimize ballistic interplanetary missions from Earth park orbit to encounter at Mars. The software assumes that interplanetary injection occurs impulsively from a circular Earth park orbit. The B-plane coordinates are expressed in a Mars-centered (areocentric) mean equator and IAU node of epoch coordinate system. B-plane targets are enforced using either a combination of periapsis radius and orbital inclination, individual B-plane coordinates of the arrival hyperbola, or entry interface (EI) conditions at Mars. The type of targeting and the target values are defined by the user.
