Engineering the Final Frontier: The Role of Chemical and Process Systems Engineering in Space Exploration

Space exploration demands the integration of multiple scientific and engineering disciplines, with chemical engineering and process systems engineering playing pivotal roles. This paper examines their critical contributions to propulsion systems, life support mechanisms, and advanced materials essential for space missions. Recent advancements in chemical propellants and rocket fuels, illustrated by SpaceX and NASA missions, have significantly improved propulsion efficiency and safety. Chemical engineering is vital in developing air purification, water recycling, and bioregenerative life support systems, ensuring astronaut survival and mission sustainability. Additionally, creating heat-resistant, lightweight materials enhances spacecraft durability under extreme space conditions. Process systems engineering (PSE) complements these efforts by integrating, simulating, and controlling complex systems. PSE ensures reliable subsystem integration and uses predictive analytics and advanced modeling for mission planning and risk mitigation. Automation and control systems are essential for maintaining operations with minimal human intervention. The synergy between these fields is evident in in-situ resource utilization (ISRU) technologies, which extract and process local resources on extraterrestrial bodies, reducing reliance on Earth supplies and enhancing mission viability. Despite significant progress, challenges remain. Addressing harsh space environments, ensuring long-duration mission sustainability, and advancing energy sources and materials are ongoing research areas. This presentation underscores the indispensable roles of chemical and process systems engineering in overcoming space exploration challenges.
