About

Grant Wells is a leading aerospace engineer whose research focuses on the critical challenge of entry, descent, and landing (EDL) systems for planetary exploration, particularly for future human missions to Mars. His most influential work, "Sizing of an Entry, Descent, and Landing System for Human Mars Exploration" (2006, 18 citations), tackles the formidable task of landing 40 to 80 metric tons—far exceeding the capability of any robotic mission. This paper provides foundational sizing and architectural analysis for the massive aeroshells and parachutes required, directly informing NASA’s long-term human exploration strategy. Wells also developed a "Planetary Entry System Synthesis Tool" (2005, 6 citations), an integrated framework that enables rapid conceptual design and multidisciplinary analysis for both EDL and aerocapture missions. By creating this tool, he empowered engineers to model complex trade-offs between aerodynamics, thermal protection, and structural design early in the mission planning process. Wells’s work bridges the gap between robotic precursor missions and the monumental engineering required to safely deliver humans to the Martian surface, making him a key contributor to the next era of space exploration.
