Human missions to Mars are a significant subject owing to NASA's and SpaceX's vast efforts to accomplish them within the next few decades. The establishment of return missions is a crucial prerequisite for the recovery of human life after successful Mars missions. The most promising strategy is the utilization of a Mars ascent vehicle (MAV) for transfer between the surface and the orbit of Mars, while the transport between Mars orbit and earth is realized via an earth return vehicle (ERV) . The required fuel for the launch into the Mars orbit via MAV can either be carried from earth and stored at the Mars surface or it can be produced on Mars.
