This advanced asynchronous course explores the principles, techniques, and strategic implications of Rendezvous and Proximity Operations (RPO) in space. With a focus on dual-use technologies, students will examine how RPO supports essential missions such as inspection, repair, refueling, and debris removal—while also considering its potential as a threat vector in contested environments. The course walks through the full RPO lifecycle, from launch to on-orbit maneuvers, giving students a comprehensive understanding of both operational utility and national security concerns in an increasingly congested and contested space domain.
