The Proceedings of the 3rd International Symposium on Reducing the Cost of Spacecraft Ground Systems and Operations bring together papers contributed by the authors representing the research organizations academic institutions and commercial sectors of 10 countries around the world. The papers encompass the subject areas in mission planning and operation TTampC systems mission control centers and mini and small satellite support highlighting the issues concerned by the researchers and engineers involved in a wide range of space programs and space industries.
