Title: From Concept to Exploration: The MBSE Approach to NASA's Planetary Rover Programs Excerpt: NASA's planetary rover programs have revolutionized space exploration, paving the way for groundbreaking discoveries on distant celestial bodies. Behind these remarkable achievements lies a systematic and robust approach known as Model-Based Systems Engineering (MBSE). This analytical methodology, employed throughout the rover's conceptualization to its actual exploration, has played a pivotal role in ensuring mission success and enhancing our understanding of the universe. By synergizing rigorous modeling techniques with a professional tone, MBSE has become an indispensable tool for NASA, propelling the planetary rover programs into unprecedented realms of knowledge acquisition.
