An MBSE-based Approach to Architecting a Robotic Sample Capture System Concept for Potential Mars Sample Return

A model-based systems engineering (MBSE) approach was applied to architecting an orbiting sample Capture and Orient Module (COM) system concept for a Capture, Contain, and Return System (CCRS) payload concept for the notional Mars Sample Return (MSR) campaign at the NASA Jet Propulsion Laboratory. An architecture framework was established, covering multiple organizational layers of the system, along with structural, behavioral, data, and requirements perspectives. A workflow process to implement the architecting activities within the COM engineering team was established. The approach helped maintain consistency in terminology, helped ensure alignment of structural, behavioral, data, and requirements elements within each organization layer, and guided the engineering team through an architecting process that helped develop the architecture for a Capture and Orient Module system concept.
