Fundamentals of Space Mechanical Systems Lubrication for GN&C Engineers

Welcome to our latest NASA Engineering and Safety Center (NESC) webcast! In this episode, Dr. Michael Dubie, NASA Technical Fellow for Mechanical Systems, takes us on a deep dive into the fascinating world of space lubrication. Discover how NASA keeps its spacecraft mechanisms running smoothly in the harsh environment of space, from reaction wheels to deployable systems. 🔑 Key Topics Covered: Friction & Viscosity: Learn the science behind friction and how lubricants reduce wear in space mechanisms. Lubrication Regimes: Understand the Stribeck curve and how NASA engineers choose the right lubrication for different applications. Space Lubricants: Explore the two main types of lubricants used in space—hydrocarbon-based (MACs) and perfluoropolyethers (PFPEs)—and their pros and cons. Bearing Anomalies: Hear about real-world challenges, including the famous Kepler Reaction Wheel anomaly, and how NASA troubleshoots lubrication issues in space. Testing & Radiation Hardening: Find out how NASA tests lubricants to ensure they can withstand extreme temperatures, vacuum, and radiation. 💡 Why Watch? Whether you're an engineer, a space enthusiast, or just curious about how NASA solves complex problems, this webcast is packed with insider knowledge and practical insights that you won't find anywhere else. #NASA #SpaceEngineering #LubricationScience #SpaceTech #GNC #MechanicalEngineering #SpaceExploration #STEM 👍 Don't forget to like, comment, and subscribe
