Plan Generation for Autonomous Small Spacecraft Swarms

Spacecraft operators are increasingly exploring distributed mission concepts and moving to more remote regimes, presenting new technical challenges that can be addressed by onboard autonomy capabilities. Onboard planning enables new tasks to be assimilated independently of ground commands, enhancing near-Earthnbsp;operationsnbsp;and enabling remote operations. Modern sensor algorithms can run locally on spacecraft to detect potential tasks, such as data collection opportunities for civil science missions, or launch events for defense missions. Planning capabilities are needed to prioritize and schedule tasks with overlapping windows of opportunity without the need for human intervention.nbsp;nbsp;Our proposed innovation, which we callnbsp;Adjutant, is flight software (FSW) for planning that leverages state of the art optimization methods for scalability and relevance to current operations, an open systems approach to plan management from multiple sources, and code generation to simplify mission integration and reduce development time for operators. Adjutant is directly relevant to applications identified in our subtopic, such as missions operating ldquo;autonomously and cooperatively at cislunar or more remote destinationsrdquo; by reducing and eventually eliminating the need for ldquo;ground-based semiautonomous schedulingrdquo;. Reducing the need for ground-based operations enables more efficient operation of near-Earthnbsp;constellations, andnbsp;can be extended to enable persistent remote operations in Cislunar or more remote environments.nbsp;Our proposed Phase II extension will develop FSW prototypes of planning, goal monitoring, and plan management applications. In conjunction with our existing FSW applications, Adjutant will enable onboard planning and execution of complex missions, including activities such as station keeping, navigation, and fault recovery. Onboard planning will support missions including Earth science such as Landsat Next,nbsp;heliophysicsnbsp;such as GDC, and exploration such asnbsp;LunaNet.nbsp;
