This is a $1,953,008 grant awarded by the National Aeronautics and Space Administration (NASA) to Arizona State University (ASU) to conduct research on the early history of the solar system. The objective is to better understand processes in the solar nebula and on planetesimals through investigations of radiogenic isotope systematics, stable isotope systematics, and trace element geochemistry of primitive and differentiated meteorites. The research addresses NASA's Emerging Worlds program goals...
This is a $382,737.21 grant awarded by the National Aeronautics and Space Administration (NASA) to Arizona State University (ASU) to conduct research on the formation conditions of volatile-bearing and water-deposited minerals on the dwarf planet Ceres. The research aims to constrain the chemistry, mineralogy, and physical processes involved in water-rock interaction in carbon dioxide- and ammonia-rich systems on Ceres, as well as model post-impact aqueous processes that may have formed the...
The National Aeronautics and Space Administration (NASA) awarded a $122,554.49 training grant to Arizona State University (ASU) to investigate the behavior of iron (Fe) and silicon (Si) isotopes during planetary accretion and differentiation. The study aims to determine if variable redox conditions during these processes are responsible for the mass-dependent Fe and Si isotope fractionation observed in planetary materials. The work will utilize analytical techniques including electron microprobe...
This is a $398,003.80 grant to the California Institute of Technology (Caltech) from the National Aeronautics and Space Administration (NASA) to conduct a joint laboratory and modeling study of photochemical processes important to the Martian water cycle and hydrogen escape. The study aims to examine the role of key reactions in the odd hydrogen (H, OH, HO2, H2O2, HOCO) radical chemistry on seasonal variations of Martian hydrogen escape and the deuterium-to-hydrogen (D/H) ratio in the hydrogen...
Arizona State University was awarded a $374,620.96 grant from the National Aeronautics and Space Administration (NASA) to conduct research related to oxygen isotope fractionation and self-shielding in the solar nebula. The research aims to improve understanding of how carbon monoxide (CO) self-shielding can explain enrichment of oxygen-17 and oxygen-18 in terrestrial planets and meteorites compared to the solar photosphere. The grant involves analyzing high-quality ultraviolet absorption...
This $704,133 NASA grant was awarded to Arizona State University (ASU) to conduct research related to the global redox state of the mid-Proterozoic oceans and its relationship to the evolution of early eukaryotes. The research aims to refine the use of uranium isotopes as a proxy to better constrain oxygen levels during this critical period in Earth's history. The work involves experimental studies, analysis of modern analogue environments, and integration with ASU's existing dataset on...
This is a $344,226 grant awarded by the National Aeronautics and Space Administration (NASA) Shared Services Center to the Desert Research Institute, a division of the Nevada System of Higher Education. The grant is for research to understand the history of water on Mars, which is critical to the search for evidence of life on the planet. The research will utilize physics-based wave modeling and geomorphic analysis to constrain the durations over which lakes existed on Mars by comparing to...
This is a $175,963 grant awarded by NASA to Arizona State University (ASU) for research on the tolerance of life to low temperature and water availability, which is key to the search for life on Mars and icy worlds. The grant has a performance period ending on January 14, 2025. ASU is a comprehensive public research university and a registered recipient of federal awards. It has a long history of federal contract and grant awards, including over $720,000 from NASA for exoplanet atmosphere...
This is a $106,000 grant award from the National Aeronautics and Space Administration (NASA) Shared Services Center to Arizona State University (ASU) for research related to the analysis of oxygen isotopes from samples returned from the Long Duration Exposure Facility (LDEF) mission. The research involves using ion microprobe measurements to analyze oxygen isotope ratios (D17O and D18O) in aluminum targets from different LDEF experiments. It also includes modeling the implantation of oxygen ions...
This is a $524,788.00 grant awarded by the Shared Services Center (SSC), a civilian agency, to Arizona State University (ASU) to conduct research on "IRON AND ITS IMPACT IN MAGMA OCEANS OF EMERGING ROCKY PLANETS." The award has an ultimate completion date of October 6, 2027. ASU, a Hispanic-serving and state-controlled institution of higher learning, has extensive experience executing federal contracts and grants across various disciplines, including space science, engineering, and...
This $444,408 grant from NASA's Solar System Workings program was awarded to Arizona State University (ASU) to better understand the origin of variability in deuterium-to-hydrogen (D/H) ratios and redox conditions within Martian meteorites.
The research aims to evaluate the effects of hydrogen loss from hydrous Martian magmas and fractional crystallization. For the first phase, ASU will measure D/H ratios, water abundances, Fe3+/Fe, and trace/minor element abundances in terrestrial analog materials to establish baseline data. In the second phase, ASU will conduct similar detailed analyses on minerals from selected Martian meteorites to investigate the roles of hydrogen loss and fractional crystallization.
The work will advance understanding of the origin of water in Martian magmas, as well as the redox evolution and D/H ratio of the Martian mantle, crust, and hydrosphere. No set-aside designation was indicated for this grant award.
