About

Bob Ritter is a leading figure in space systems engineering, with a primary focus on spacecraft modularity and on-orbit satellite servicing. His most influential work, "Spacecraft Modularity for Serviceable Satellites" (2015), has garnered 15 citations and stands as a foundational reference in the field. Ritter’s research demonstrates how modular satellite architectures can enable cost-effective repair, refueling, and upgrade missions—capabilities proven by NASA since the 1980s, from the Space Shuttle era to the International Space Station and the Hubble Space Telescope servicing missions. By translating these historic successes into design principles for future spacecraft, Ritter has helped shape the technical roadmap for next-generation, serviceable satellite systems. His contributions are critical for advancing sustainable space infrastructure, reducing orbital debris, and lowering mission lifecycle costs. For students and researchers, Ritter’s work offers a clear bridge between past engineering triumphs and the future of resilient, maintainable space assets.
