Trajectory Planner is a computer program that helps in determining the most optimal trajectory for a spacecraft to transfer from one planet to another. To determine a transfer orbit, the program calculates separate orbits for every possible launch and arrival date combination within a specified range, and outputs them as pixels on a graph (often called a "pork-chop plot").
