The National Aeronautics and Space Administration (NASA) awarded a $601,513.51 grant to the University of Maryland, College Park to study the population of potentially hazardous near-Sun objects, as well as related comets and asteroids. The goal is to reduce the orbital uncertainties and constrain the physical and dynamical properties of these objects, which can pose a threat to Earth. The work is responsive to NASA's Near-Earth Object Observations (NEOO) program, as it will improve knowledge...
This is a $123,720.00 grant awarded by the National Aeronautics and Space Administration (NASA) to the University of Maryland, College Park for research to improve and augment the database of hydrometeor single-scattering properties to support algorithm development. The key objectives are to construct an improved version of the single-scattering property database to better represent natural variations, including growing larger synthetic pristine ice crystals, simulating polycrystal formation,...
This is a $149,945 cooperative agreement awarded by the National Aeronautics and Space Administration (NASA) to the University of Maryland, College Park to investigate the characteristics of regolith (surface material) and its interaction with the plasma environment on small bodies as part of the DREAM2 Solar System Exploration Research Virtual Institute (SSERVI) node at Goddard Space Flight Center.

The grant, with a period of performance through June 1, 2023, is an Early Career Award that builds on the awardee's existing expertise in this field. The University of Maryland, College Park is a state-controlled institution of higher...
This is a $169,822 grant awarded by the National Aeronautics and Space Administration (NASA) to the University of Maryland, College Park to characterize the transport and impact of African dust in the Caribbean basin. The university will integrate ground observations, satellite measurements, and NASA GEOS-5 model simulations to gain a comprehensive understanding of this phenomenon, which can affect human health, coral reefs, ocean biogeochemistry, weather, and climate. There is no set-aside...
This is a $79,317.28 grant contract awarded by the National Aeronautics and Space Administration (NASA) to the University of Maryland, College Park. The grant's main goals are to constrain the provenance of material comprising the solar nebula and provide new constraints on the timing of very early solar system fractionation processes. The University of Maryland will obtain siderophile element chemical and isotopic data from cosmochemical materials to determine if there is direct evidence of...
This is a grant awarded by the National Aeronautics and Space Administration (NASA) to the University of Maryland, College Park (UMD) to develop the next generation of photonics spectrometers and filters for astrophysics and space science applications. The $860,473.64 grant aims to broaden the wavelength range, increase the spectral resolving power, and improve the polarization independence and throughput of the university's existing photonic spectrometer and filter prototypes. This effort...
This federal contract award, valued at $390,286.00, was granted to the University of Maryland, College Park by the National Aeronautics and Space Administration (NASA) to carry out computer-based simulations of the spin-evolution of small near-Earth asteroids. The goal is to realistically model the response of aggregate asteroids to rotational stresses in order to interpret observational data and determine the strength parameters of these objects. The project aims to address key unanswered...
This is a $129,106.47 grant awarded by the National Aeronautics and Space Administration (NASA) to the University of Maryland, College Park (UMD) on April 14, 2021. The grant supports the development or validation of software tools for planetary science, as requested in NASA's Planetary Data Archiving, Restoration, and Tools (PDART) solicitation. This research work will contribute to NASA's goal of producing tools that enable or enhance future scientific investigations. The grant does not have a...
The National Aeronautics and Space Administration (NASA) awarded a $300,883.99 grant to the University of Maryland, College Park to develop and apply a software package for modeling light scattering by particulate surfaces on various solar system bodies. The project aims to generate a high-accuracy solution to the macroscopic Maxwell's wave equations for random regolith layers, which can be used to study the spectral and photometric characteristics of dust and icy particles on asteroids, comets, and planetary satellites. The grant does not have a set-aside designation. The University of Maryland, College Park, as the prime contractor, will finalize the code during the first year of the grant period and then apply it to further work on understanding the opposition effect using existing datasets.
