![]() Modern space debris regulations demand that such incidents should not happen. The numbers are gradually improving, but it is not fast enough." The uncontrolled tumbling created a panic among nations, putting people and property in danger.ĮSA, in its report, said, "More than half of space actors operating the non-compliant missions make no attempt to sustainably dispose of their missions. While the rocket landed in the Indian Ocean last week, the bulk of its components was destroyed upon re-entry into the Earth's atmosphere. China was recently in the news when its biggest rocket, Long March 5, started tumbling back towards Earth after the delivery of a critical component of its under-construction space station.Īlso Read: China to send 3 astronauts to its under-construction space station for three months in June With several countries funnelling billions of dollars into space missions, responsible exploration and management are key. (Graph: ESA) Space operators not doing enough This thesis represents a contribution to the advancement of constellation systems by assessing the viability of the existing paradigm and identifying critical areas of future research.Commercial satellite sky-rocket in low-Earth orbit. The new generation of constellations is challenging the assumptions that have traditionally guided such analyses, and opportunities for further framework development are discussed. Through a series of cost and risk focused case studies, limitations within the existing development and maintenance paradigms are illustrated. Contemporary issues in constellation technology policy are also examined. This work continues by underscoring technologies that have enabled this growth through a survey of relevant literature and patent filings. The second generation of LEO constellations coincides with an approximately 189% increase in the annual NGSO satellite launch rate and a 92% increase in the number of constellation systems initialized each year over the first generation. ![]() Growth rates surge again as the second generation begins in 2010, and the data reflect current trends toward commercial, remote-sensing applications of DSM systems. It begins with the installation of the first commercial, telecommunications constellations and demonstrates logistic growth for commercial DSM member spacecraft. The first generation spans from 1997 to 2009. The initial time period, 1959 to 1996, captures the early DSMs that framed the development of modern systems. The investigation begins with a discussion of the historical development of DSMs, and three distinct eras of constellation use are identified. Through a multidisciplinary, systems engineering evaluation, this thesis synthesizes current knowledge gaps and questions related to second-generation LEO constellations. ![]() ![]() LEO constellations are becoming essential tools for a wide range of applications, and this work seeks to examine the diverse set of topics facing modern constellation stakeholders. The most significant value of this research effort comes from its breadth. A new generation of LEO constellations is emerging, and understanding the related technical, economic, and policy landscapes will be critical to fostering their success. Modern proposals for Low Earth Orbit (LEO) satellite constellations underscore the tremendous potential and versatility of distributed spacecraft missions (DSMs), but they have also begun to stress the limits of the existing development paradigm. ![]()
