The Jacobsen group collaborates with NASA, ICON Technology Inc., and interdisciplinary research teams through NASA's Moon to Mars Planetary Autonomous Construction Technology (MMPACT) program to investigate how lunar regolith can be transformed into durable construction materials for future lunar infrastructure. Our work focuses on characterizing materials made with the Vitreous Multi-material Transformation (VMX) process, a laser-based additive manufacturing process that melts lunar regolith to fabricate landing pads, roads, and other critical infrastructure directly from materials already present on the Moon. My research uses advanced electron microscopy techniques, including SEM, EDS, and EBSD, to characterize the microstructure, mineralogy, and crystallographic textures that develop during printing. By linking processing conditions to the resulting material properties, we aim to optimize lunar construction methods that will support autonomous, long-term human exploration beyond Earth while reducing the need to transport building materials from Earth.
