... TITLE AND CONTEXT Notably, the focus of this document has changed relative to prior NASA science plans;1,2,3 it no longer represents a plan for executing missions and conducting science but instead conveys a set of guiding principles adopted by the SMD, recognizing the key role of the decadal surveys in setting priorities and science goals.4,5,6,7 As such, the draft document's title, Explore Science 2019-2024: A Vision for Scientific Excellence, does not present it as a "science plan." The draft document introduces four cross-cutting foci under the heading of "Science Leadership Priorities" -- Exploration and Scientific Discovery, Innovation, Interconnectivity and Partnerships, and Inspiration -- and describes strategies within these focus areas. However, the title of the draft document does not clearly convey the content.
