    Characterization of lunar crust with moon mineralogy mapper data
    (2015-06-09) Sun, Ying; Lin, Li; Bird, Broxton; Johnson, Daniel; Licht, Kathy; Gilhooly, William P.
    This dissertation has three main focuses: (1) identify the distribution of a new rock type (Mg-spinel lithology) on the Moon and explore the likely petrogenesis of Mg-spinel; (2) investigate the presence of olivine in the crater central peaks and analyze the sources of olivine; (3) determine the compositional variations of lunar crust with depth, and establish a new model to describe the structure of the lunar crust.

    Natural Gamma Transmutation Studies
    (American Astronomical Society, 2021) Schubert, Peter J.; Electrical and Computer Engineering, Purdue School of Engineering and Technology
    Beyond Earth’s magnetosphere is a spectrum of extra-gallactic energetic photons of mysterious origin. Called the “gamma fog” this source of gamma rays provides a unique opportunity to study neutron generation (from beryllium) and the use of such neutrons to transmute elements found in the lunar crust. There are also many commercial applications.
