Measuring Lunar Surface (IMAGE) Southwest Research Institute Caption A new study by a recent graduate of SwRI’s joint graduate program in physics with UTSA shows that the Lyman-Alpha Mapping Project (LAMP), a SwRI-created mapping instrument aboard NASA’s Lunar Reconnaissance Orbiter (LRO), can determine the composition of areas on the lunar surface by measuring the reflectance of far-ultraviolet light. Top image shows younger, less mature features such as impact craters and rays while the bottom image shows these features removed by the study’s newly reported methods, providing compositionally distinct features for subsequent analysis.
