About

Roger Chiei is a leading figure in the field of in-space robotic servicing and autonomous space exploration, with a career focused on advancing the technologies that enable satellites and spacecraft to be repaired, refueled, and upgraded in orbit. As a key contributor to NASA’s Satellite Servicing Capabilities Office (SSCO) at the Goddard Space Flight Center, Chiei has been instrumental in maturing robotic and automation technologies that bridge the gap between terrestrial robotics and the harsh demands of space. His most-cited paper, "Advances in Robotic Servicing Technology Development" (2015), with 22 citations, synthesizes six years of progress in developing dexterous manipulators, sensor systems, and autonomous control algorithms—work that directly underpins missions like OSIRIS-REx and the upcoming Restore-L satellite servicing demonstration. Chiei’s contributions have not only extended the operational lifespan of costly space assets but also laid the groundwork for future robotic exploration of the Moon, Mars, and beyond. His research is a cornerstone for students and engineers seeking to understand how robotic systems can perform complex tasks in zero gravity, making him a pivotal voice in the next era of sustainable spaceflight.
