Summary

Description

<p>Mission design within unstable/stable regions needs unification of individual trajectories from different dynamical regimes. NASA needs an automated process to blend multiple dynamical systems to flow topologically different orbital arcs together easily.</p><ul><li>Develop an automated process which blends single and multi-body trajectory arcs</li><li>Combine  various trajectory design concepts into a unified and continuous path quickly and efficiently</li><li>End goal is a process and developmental software to blend different types of mission design trajectories</li></ul><p>We will perform the following:</p><p>Incorporate additional capabilities for generation of dynamical (Poincaré) maps to assess options and choose the best blend for orbit selection and initial conditions, and capabilities for any sun/planet or planet/moon combination (current algorithms can be reused).</p><p>Interface ATD with the Goddard Mission Analysis Tool (GMAT) for routine use by the GSFC Navigation and Mission Design Branch. Complete the structure of the algorithm such that future theoretical and technical developments can be easily incorporated.</p><p>End goal and product is a process and developmental software to blend different types of mission design trajectories into one optimal design. The process will have a theoretical basis but offers an automated structure and, ultimately, with an optimization step incorporated as well.</p><ol style="list-style-type: lower-alpha;"><li>Demonstrate the capability to incorporate trajectory arcs from the following regimes:  Earth and Lunar conic; Earth-Moon libration; and Earth-Sun to meet the mission requirements for upcoming missions such as JWST, Earth-Moon libration habitat orbits, and offer a design space for trade-offs.</li><li>Begin application to other Sun-planet systems, EML2-Mars transfers, Earth-Moon resonant orbit design, and asteroids encounters for OSIRIS applications.</li><li>Establish ATD as a routine mission design process for efficient combination of various trajectory design concepts into a unified and continuous path.</li></ol><p>Leverage of a NASA Space Technology Research Fellowship (NSTRF).</p><p> </p>
