Origin and evolution of lunar volatiles

Organization National Aeronautics and Space Administration (NASA) Reference Code 0300-NPP-NOV26-GSFC-PlanetSci Description The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology. Studies of astromaterials, including meteorites and samples returned by missions, enable deeper understanding of the origin and evolution of the solar system. The physical and chemical makeup of these samples record properties and processes including the presolar environment, nebular reservoirs from which planetary bodies formed, accretion, impact events, differentiation, volcanism, and space weathering. All of these factors played a role in establishing the volatile composition of the Moon. Understanding the origin and evolution of these volatiles is fundamental to understanding the history of life on Earth and is critical for in situ resource utilization as humanity seeks to build a sustained presence beyond low Earth orbit. Volatiles are also central to the lunar and planetary science goals of NASA’s Moon to Mars program. Research projects to better understand lunar volatiles and their solar system origins can include mineralogic and petrologic studies, geochemistry (one or more of elements, isotopes, organics), experimental analogs, or modeling. Techniques may include but are not limited to electron microscopy, X-ray computed tomography, infrared spectroscopy, and mass spectrometry. Projects may also be conducted that align with the goals of sample return missions, such as Artemis, Mars Sample Return, or future comet/asteroid/moon sample return concepts; such projects would primarily focus on fundamental science questions and may or may not lead to direct connection to any given mission. The interdisciplinary nature of this work provides opportunity for candidates with diverse scientific backgrounds. Similarly, developing a better understanding of the Moon’s endogenous vs exogenous volatiles will require many threads of research, so candidates may address or have experience in broader questions of formation, accretion and transport of primitive materials such as asteroids and comets, or of volatiles in early lunar/planetary igneous processes.
