Interplanetary Mission Planner & Verifier

Modeling and verification of interplanetary missions using Kepler & Newton.

These code sets enable the determination of interplanetary missions - along the lines of the Voyager missions. There are two primary functions - determining a feasible trajectory using Keplerian methods , then verifying the determined trajectory using Newtonian methods.
The Keplerian methods for trajectory are fast to determine, but comparatively 'coarse'. The Newtonian method is very accurate at verifying a trajectory, but VERY slow to calculate.
LIMITATIONS - to keep it simple, the solar system is 2D, and the planetary orbits are perfectly circular.

(update) - the target planets can be set by changing the planet on line 88 (part1_keplerian_trajectory.m), and the miss distances for the planets being passed (line 88). This would be more effective with a GUI - I will look at this when time permits.

There are better developers out there and I welcome your comments, both for the trajectory methods and the code efficiency.
Best wishes,
Stephen
