The Journal of the Astronautical Sciences was founded in 1954 as an archival publication devoted to the science and technology of astronautics. It publishes Original Research and Technical Notes that present significant new results, important insights, or state of the art surveys in all areas of astrodynamics, celestial mechanics, atmospheric flight mechanics, navigation and guidance, and space related sciences. Authors are encouraged to submit papers on attitude dynamics, orbit determination, trajectory optimization, space missions analysis, numerical methods, maneuvering flight vehicles, dynamics and control of large flexible space structures, and space science related to new astronautical systems and their applications. Article Types The Research article type denotes a complete, comprehensive report of original research with demonstrated and explained novelty, relevance, significance, quality and applicability. Methods and results must be described and discussed. The Brief Report (replacing the former Technical Note) should present a device, hardware design, software tool, computational method, test or procedure within the scope of the journal. The method described may be new or may be an update or adaptation of an existing one. All suitable submissions are peer-reviewed. .
