Abstract NASA's Europa Clipper mission will investigate the Jovian icy moon Europa with a sophisticated payload consisting of a suite of nine instruments. Clipper's observations will help provide answers to a broad range of scientific objectives related to Europa's habitability. As the project proceeds through Phase C, we are building confidence in the system's ability to achieve these science goals by implementing a rigorous payload verification and validation (V&V) program. This paper details the planned structure and implementation of the Europa Clipper payload V&V program as it exists leading up to the project critical design review (CDR), before the bulk of instrument- or payload- level V&V activities have begun. We first explain the context for payload V&V on Europa Clipper, including its interfaces with other parts of the project system. We then describe the taxonomy of V&V concepts and their interrelationships, followed by a discussion on how this framework allows us to codify interfaces, processes, and ideas that are key to a successful V&V program. We focus on key aspects of the planning phases of V&V, especially establishing a complete set of verification items and accurately mapping them into appropriate verification activities. The second half of the paper describes the logistics of implementing this framework onto our actual payload system, including the processes and tools we use to manage and communicate agreements, changes, and risks across the project. We conclude with a reflection on the unique drivers and challenges of the V&V program concept development so far and the work that is planned for phase D implementation.
