From Capability to Accessibility: A Usability Heuristics Approach to Space Mission Planning Tools

Abstract: Designing and operating space missions is a technically demanding and iterative process that requires engineers to balance spacecraft design, mission requirements, and trajectory optimization. Existing aerospace software tools, while technically sophisticated, often lack accessibility and usability, unintentionally excluding users with diverse physical, cognitive, and sensory needs. This gap between capability and inclusivity limits participation in mission design, particularly in educational contexts where accessibility is essential. This paper presents a novel framework for embedding human factors and accessibility principles into the architecture of aerospace mission design tools. Drawing on usability heuristics and Universal Design for Learning (UDL) principles, we develop three core contributions: (1) accessibility heuristics that translate inclusive design standards into actionable requirements for aerospace applications, (2) a comprehensive ruleset for architecture design focusing on progressive disclosure, multimodal representation, and user-centred interaction patterns within mission planning interfaces, 3) improved aesthetics compared to legacy mission planning applications, reducing visual clutter and cognitive load. Together, these artifacts form a methodology for systematically applying usability principles to aerospace system architecture. By embedding accessibility at the architectural level, the platform moves beyond compliance to actively support engagement, comprehension, and collaboration.
