Design and Optimization of Spacecraft Trajectories for Cislunar Transportation and Beyond

The establishment of space stations and logistics hubs in cislunar space could serve as waypoints for spacecraft, reducing the cost and complexity of missions to the Moon, asteroids, Mars, and beyond. The Lunar Gateway is a planned space station in the near-rectilinear halo orbit or distant retrograde orbit near the Moon, developed by NASA and international partners. It will support various missions, from crewed lunar landings to scientific research. Furthermore, the European Space Agency (ESA) is planning the deployment of a communication and navigation network within the lunar region.

Given these strategic initiatives, it is essential to investigate and develop technologies that enhance exploration, transportation, and resource retrieval in cislunar space. This PhD project will focus on developing techniques and software to rapidly identify low-cost spacecraft trajectories between Earth and the Moon, as well as between the Moon and outer space, considering mission budgets, specific requirements, and post-failure conditions.

The candidate is encouraged to apply analytical Astrodynamics techniques—providing insights into dynamics governed by the gravitational forces of the Sun, Earth, and Moon, facilitating dimension reduction and visualization of low-energy pathways—alongside numerical and empirical machine learning techniques that balance modelling accuracy and processing speed.

This project offers a unique opportunity to make significant contributions to the emerging cislunar economy and near-future planetary exploration efforts by enabling the transportation crucial for sustainable and cost-effective space missions.
