- This is a $338,303.17 grant awarded by NASA to the University of Arizona, doing business as the Arizona Board of Regents, to analyze observations of the UV airglow emissions from Saturn's upper atmosphere using the Hubble Space Telescope's UVIS instrument. The analysis will investigate the structure of Saturn's thermosphere and constrain the hydrogen abundance and energy deposition processes. This research will also facilitate studies of Saturn's ionosphere, the interaction of the ring system...
- This federal contract award was granted by a civilian U.S. government agency to the University of Arizona, doing business as the Arizona Board of Regents, a public research university. The $350,641 grant is for research to probe the atmosphere of Titan, Saturn's largest moon, using data from the Cassini spacecraft's Composite Infrared Spectrometer (CIRS), Ultraviolet Imaging Spectrograph (UVIS), and Ion and Neutral Mass Spectrometer (INMS) instruments. The research aims to determine the vertical...
- This is a $321,657 grant awarded by the Shared Services Center of the National Aeronautics and Space Administration (NASA) to the University of Arizona, doing business as the Arizona Board of Regents. The grant is for research related to NASA's Cassini mission to Saturn, which studied the planet's atmosphere and Titan's methane-based weather systems. As a public research university and 1862 land grant institution, the University of Arizona has extensive expertise across scientific and...
- This federal contract award, valued at $465,182.00, was granted to the University of Arizona, doing business as the Arizona Board of Regents, by the National Aeronautics and Space Administration (NASA) Shared Services Center. The contract is a grant for research related to the Cassini mission, which provided unprecedented observations of Saturn's upper atmosphere during its 13-year orbit. The award does not have a set-aside designation and is for a performance period ending on April 30, 2026....
- The University of Arizona, doing business as the Arizona Board of Regents, has been awarded a $312,650 grant by the National Aeronautics and Space Administration (NASA) Shared Services Center. As the prime contractor, the University will support NASA's research efforts by analyzing approximately 19,500 images of Titan taken by the Cassini spacecraft's imaging science subsystem at a wavelength of 938 nanometers, which provides the best window for probing Titan's surface composition using this...
- This $120,000.00 contract was awarded by the National Aeronautics and Space Administration (NASA) to the University of Arizona, doing business as the Arizona Board of Regents, to conduct research on resistive heating and ion drag in Saturn's equatorial thermosphere. The goal is to investigate whether these mechanisms can explain the observed high temperatures in Saturn's thermosphere, which cannot be fully accounted for by solar heating alone. This research directly addresses NASA's "energy...
- The University of Arizona, operating through the Arizona Board of Regents, has been awarded a $464,102 research grant by a civilian federal agency to develop a comprehensive atmospheric escape model for transiting exoplanets. The research project, with an ultimate completion date of December 31, 2026, addresses fundamental questions about how atmospheric mass loss shapes the population and composition of exoplanets, with particular focus on planets at the boundary of the "hot Neptune...
- This is a $102,368.37 grant awarded by the National Aeronautics and Space Administration (NASA) to the University of Arizona (dba Arizona Board of Regents) for research on Titan's atmosphere and climate. The grant supports the analysis of existing spectral data from the Keck Observatory to measure the seasonal and latitudinal variations in Titan's tropospheric methane. The research aims to improve understanding of Titan's climate, including cloud, storm, and rain processes, and the transport...
- This is a $236,995.00 federal grant award from the Shared Services Center (an agency within NASA) to the Planetary Science Institute (PSI), a non-profit research organization based in Tucson, Arizona. The grant funds a research project to study the presence and role of non-ice materials in the Saturnian system, utilizing the unique characteristics of the ultraviolet (UV) spectral range. Key objectives include investigating the nature of dark, non-ice species on several of Saturn's moons and...
- The University of Arizona, operating as the Arizona Board of Regents, received a $489,045 research grant from a civilian federal agency with an ultimate completion date of August 7, 2026. This grant supports research on the characterization of exoplanets through improved understanding of host star properties, with particular emphasis on modeling exoplanet atmospheres where stellar irradiation drives atmospheric conditions. The research addresses significant gaps in current stellar modeling...
The University of Arizona (operating as the Arizona Board of Regents) received a $443,494.91 research grant awarded on June 1, 2019, by a civilian federal agency with an ultimate completion date of May 31, 2025. The grant supports continued analysis of Saturn's upper atmosphere using data from the Cassini Ultraviolet Imaging Spectrograph (UVIS) instrument. The research builds upon previous occultation observations that have provided extensive constraints on Saturn's atmospheric density, composition, and temperature profiles across altitudes from approximately 300 kilometers to 2,700-3,000 kilometers above the planet's 1 bar pressure level. Prior analyses have revealed important findings regarding thermospheric heating mechanisms, with evidence indicating that polar auroral heating and particle precipitation significantly outweigh solar heating contributions. The project addresses remaining gaps in understanding Saturn's upper atmosphere, particularly the heating mechanisms at low to mid-latitudes outside the auroral region and the meridional circulation patterns in the planet's rapidly rotating atmosphere. The research will leverage circulation model results and integrate data from multiple Cassini instruments—including the Composite Infrared Spectrometer (CIRS) and Radio Science Subsystem (RSS)—to constrain the overall atmospheric structure, helium abundance, and energy redistribution processes. No set-aside designation was applied to this award. The work will be performed in Tucson, Arizona, where the University of Arizona maintains significant capabilities in planetary science and space exploration research through its role as a land grant and Hispanic-Serving Institution.
