The purpose of this report is to design and iterate all the subsystems of a drone for Mars exploration. Based on a design option analysis and tradeoff, the vehicle is designed to be a VTOL tilt rotor. The mission need statement is: Enable largescale targeted exploration of the atmosphere and surface of currently inaccessible areas of Mars. This mission statement resulted in two expedition types: collect and return expeditions in which soil samples are collected, and remote sensing expeditions where visual mapping, height mapping, gas analyzing and dust composition data is collected and. The project objective statement is: Design a semiautonomous unpiloted atmospheric vehicle that can assist human Martian exploration by observing remote areas and collecting atmosphere and soil samples from difficulttoreach places...
