The National Aeronautics and Space Administration (NASA) awarded a $223,650.73 grant to the University of Arizona (doing business as the Arizona Board of Regents) to conduct research under the "Mineralogical Mapping of Asteroid Itokawa Using Hayabusa AMICA Camera Multi-Spectral and NIRS Spectr" program. The 4-year grant will support the calibration and restoration of multi-color data from the Hayabusa spacecraft's Asteroid Multiband Imaging Camera (AMICA) to create global 7-color...
This federal contract award, NNX16AO78G, was granted by the National Aeronautics and Space Administration (NASA) to the University of Hawaii (UH) to develop a new spectral-based indicator of space weathering. The goal is to create a radiative transfer-based optical maturity index that overcomes the compositional biases observed in the current Optical Maturity (OMAT) parameter. The project will involve radiative transfer modeling of lunar soil samples to derive the quantitative abundance of key...
This is a grant awarded by the National Aeronautics and Space Administration (NASA) to the University of Texas at Austin for research to support the OSIRIS-REx mission to the asteroid Bennu. The goal of the research is to identify the optimal sampling site on Bennu's surface by investigating evidence of aqueous alteration and impact processing of the regolith, which is crucial for preserving any hydrous mineralogy and primitive organics. The research will leverage data from the OSIRIS-REx...
The University of Arizona, doing business as the Arizona Board of Regents, was awarded a $146,998.02 grant from the National Aeronautics and Space Administration (NASA) for scientific research related to the OSIRIS-REx mission. The grant will fund the university's efforts to refine predictions of the surface characteristics of the asteroid Bennu and adapt models as data is collected during the mission. Specifically, the university will investigate the granular dynamic activity affecting the...
This contract was awarded by the National Aeronautics and Space Administration (NASA) to the University of Hawaii at Manoa, a public university in Hawaii. The $502,189.00 grant funds research to characterize the effects of space weathering on rocky bodies in the solar system using scanning transmission electron microscopy (STEM) analysis. The research aims to improve understanding of how space weathering impacts remote compositional determinations of planetary surfaces. This work supports NASA's...
This is a $308,730.00 grant awarded by NASA to the University of Hawaii (UH) to investigate the flux and nature of extraterrestrial materials arriving on Earth and other planets over time. The research aims to study the impact history of planetary bodies and the dynamical evolution of the asteroid belt by analyzing extraterrestrial chromite grains isolated from slowly deposited sedimentary sections. This grant is part of NASA's Solar System Workings program, which seeks to understand processes...
The National Aeronautics and Space Administration (NASA) awarded a $223,930.40 grant to the University of Hawaii at Manoa to produce a space weathering map of asteroid Bennu using radiative transfer modeling. The goal is to identify the most pristine, unweathered regions on Bennu's surface to support NASA's OSIRIS-REx mission, which aims to obtain a sample of the asteroid's carbonaceous regolith. The work involves calibrating radiative transfer models to laboratory spectra of space-weathered minerals, then applying the models to data from OSIRIS-REx's Visible and Near-Infrared Spectrometer (OVIRS) to map the relative abundances of submicroscopic weathering products across Bennu's surface. This will help the OSIRIS-REx team select the optimal site for sample collection. No set-aside designation was specified in the award details.
