Topic: Study of Interplanetary Optimization between Earth and Mars Location: SENG -201 Abstract: Astrodynamics-based trajectory planning, and optimization are vital in deep space exploration mission design. Interplanetary Trajectories are the orbital paths that a spacecraft takes between a starting and destination celestial body at a certain point in time. Maximum final mass and minimal travel time are two primary parameters that are always targeted to be optimized in Interplanetary trajectory. We focused on the time aspect in our study as it is very crucial when planning any interplanetary space trip. The track between Earth and Mars from 2020 to 2050 is shown using a trajectory optimization tool. The trajectory optimization tool is based on a genetic algorithm and determines trajectories using a patched conics approximation. Time of Flight (TOF), Departure C3 energy, Arrival Velocity, and the orbital elements of the proposed orbit are the tool's output parameters. To select an orbit for Earth to Mars, we focused on getting TOF, C3 Energy, and arrival velocity in the acceptable range. Further, we utilized two open-source libraries, Pykep and PyGMO, to validate the findings achieved using the optimization tool. The outcomes were the journey time, Arrival Vinf, Departure Vinf and Insertion DV. The two approaches were evaluated in terms of trajectory view and travel time. Between the two methods, there is a significant difference in travel duration observed. The best ideal year between 2020 and 2050 will be chosen after comparing the results of the trajectory plotted and TOF obtained from the optimization tool and Pykep library used.
