Science Planning team members from the Psyche mission at NASA’s Jet Propulsion Laboratory (JPL) requested the capstone team to design and build a software tool to help science planners visually ‘diff’ two plans. In other words, given two plans (time-lists of activity instances), the tool would show science planners, in some way, a timeline with visual indicators of how activities moved (or were added/removed) between one version of the plan and another. The student team implemented this in whatever way they felt best, guided by direct feedback from JPL science planners. The Psyche science planners provided sample input files as well as sketches of what would be useful for the final diffs to look like. If done in a supportable and robust way with adequate documentation, the Psyche mission (and potentially other missions at JPL) will put this tool into use for operations.
