Characterizing Effective System Architectures for Cislunar Space Situational Awareness
Achieving Space Situational Awareness (SSA) in the Cislunar region—the area between the geosynchronous belt and the Moon's gravitational boundary—poses significant technological and organizational challenges. Instead of proposing new theoretical systems, this thesis employs the Architecting …

Optimal control techniques for multimode propulsion mission design in cislunar space
Multimode spacecraft propulsion is an emerging, enabling, and enhancing technology that combines two or more propulsive modes (e.g., chemical and electric) into one system using a single propellant. The primary benefit of this technology is that it can provide reduced propellant consumption for a …

From the Earth to the Moon: A Multi-Domain Approach to Cislunar Space Domain Awareness
Growing interest in the Cislunar domain has resulted in numerous successful Lunar missions in recent years. Many burgeoning space programs, including those by governments and private industry, have seized the opportunity of this renewed interest and utilized the region as a proving ground to bring …

Investigation Into Geometry and Behavior of Cislunar GEO-Grazer Orbits
This thesis investigates a class of cislunar trajectories referred to as GEO-grazers: orbits that traverse the Earth–Moon system while grazing or passing below geosynchronous Earth orbit (GEO). These trajectories are of interest for cislunar space domain awareness (SDA) because they provide natural …

Autonomous Space Surveillance for Arbitrary Domains
<p>Space is becoming increasingly congested every day and the task of accurately tracking satellites is paramount for the continued safe operation of both manned and unmanned space missions. In addition to new spacecraft launches, satellite break-up events and collisions generate large amounts of …

A transfer network linking Earth, Moon, and the triangular libration point regions in the Earth-Moon system
<p>In the near future, several space applications in the Earth-Moon system may require a spacecraft to hold a stable motion, but the transfer trajectory infrastructure to access such stable motions has not been fully investigated yet. The triangular libration points, <em>L</em> 4and <em>L</em>5, in …

Reusability analysis for Lunar Landers
… presented that explores the lunar lander design space to understand how reusability impacts the chosen objectives of IMLEO, life-cycle cost, and safety. The choice of reusability and the use of a cislunar space station are found to have the greatest impact on the chosen objectives. The effect of …

In Space Reverse Logistics
This study proposes In Space Reverse Logistics (ISRL), a fully reusable multi-mission network design for mitigating and remediating space debris in proliferated Low Earth Orbit (pLEO) constellations. The ISRL design aims to collect defunct satellites from their operating orbits and to bring them to …
