This federal contract award, NNX16AP50H, was granted to Arizona State University (ASU) by the National Aeronautics and Space Administration (NASA) to study the accretion of gas onto planets and the formation of planetary atmospheres. The $101,130.93 contract supports a 3-year research project that will use hydrodynamic simulations to examine how planets can accrete and retain substantial primary proto-atmospheres from the surrounding nebula gas, including cases where the planet is perturbed into...
This federal contract award, valued at $454,256.00, was granted by the National Aeronautics and Space Administration (NASA) to Arizona State University (ASU) for research related to understanding the effects of rock composition and water/CO2/rock ratios on the aqueous acid-base chemistry, secondary mineralogy, and atmospheric CO2 abundance on habitable zone exoplanets. The research aims to link aqueous processes on exoplanets with quantitative assessments of habitability, focusing on the...
This federal contract award, with an ID of 80NSSC21K1402, was granted by the Shared Services Center of the NASA agency to Arizona State University (ASU) for a research project focused on developing predictive theories to guide the search for planetary life. The $1,679,932.00 grant, which does not have a set-aside designation, will fund this scientific research initiative through October 30, 2025. ASU, a comprehensive public research university located in Tempe, Arizona, has a longstanding...
This is a $208,215.74 grant awarded by NASA to Northern Arizona University (NAU) for research related to detecting signs of life on exoplanets. The project aims to develop a tool for analyzing exoplanet atmospheric compositions to identify potential biosignatures and indications of chemical disequilibrium. The research aligns with NASA's goals of understanding Earth and searching for life elsewhere, as outlined in its strategic plan and the Exobiology program. NAU, a public research university...
Arizona State University (ASU) was awarded a $540,630 research grant by a civilian federal agency to conduct scientific research on magma oceans in rocky exoplanets, with a focus on understanding their dynamic and magnetic evolution through new models and experiments. The contract, issued on January 1, 2023, with an ultimate completion date of December 31, 2026, will be performed at ASU's Tempe, Arizona campus. This grant falls under a child entity of ASU (doing business as Orspa), which...
This is a $559,951.00 grant awarded by the National Aeronautics and Space Administration (NASA) to Arizona State University (ASU) for research on the impact of rock-ice interactions on exoplanet mass-radius relations. The research aims to develop new models and equations of state for planetary interiors that account for potential formation of rock-ice solid solutions, which could significantly affect the interpretation of exoplanet compositions based on the mass-radius relationship. The work...
This federal contract award (80NSSC18K0349) was made by NASA to Northern Arizona University (NAU) to conduct research on exoplanets and their atmospheres. The $472,252 grant supports the development of climate models and spectral databases to help distinguish between "super-Earth" terrestrial planets and "mini-Neptune" gas-rich planets, which are common in exoplanet systems. This work aims to improve NASA's ability to characterize exoplanet atmospheres through future...
This is a $852,867 research grant awarded by the National Aeronautics and Space Administration (NASA) to Arizona State University (ASU) to study the geochemical and biomolecular changes associated with the evolution of photosynthesis. The research aims to understand how geochemical changes may have enabled the historical rise of photosynthesis by examining transitions to photosynthesis in active hot spring ecosystems. The project will combine field research, laboratory analysis, and...
Arizona State University (ASU), operating through its Office of Research and Sponsored Projects Administration, received a $722,053 research grant (Contract No. 23-XRP23_2-0097) with an ultimate completion date of September 27, 2027. Titled "Let the Data Speak for Itself: Understanding the Limits of Current Exoplanetary Atmospheric Models and Their Missing Physics in a Data-Driven Era," this civilian research award supports ASU's continued investigation into exoplanet atmospheric...
This is a $488,088 research grant awarded by the National Aeronautics and Space Administration (NASA) to Arizona State University (ASU) to identify the characteristics and distribution of potentially habitable environments around low mass stars. The grant aims to quantify and explore the effects of high energy radiation on habitable zone terrestrial planets by building a statistically significant grid of updated models for the ultraviolet spectral range, which impacts the formation, chemistry,...
This federal contract award, with an ID of NNX17AB95G, was granted by the National Aeronautics and Space Administration (NASA) to Arizona State University (ASU) for a research project titled "No One's Home: The Fate of Carbon on Lifeless Earths." The $240,957 grant aims to improve the understanding of how carbon is cycled between the atmosphere, surface, and interior of terrestrial exoplanets without life. The project will involve modeling the near-surface geochemistry and geophysics of the carbon cycle, as well as the atmospheric fate of carbon species, to create a self-consistent simulation of abiotic carbon cycling. The resulting atmospheric compositions will be converted to predicted exoplanet spectra and made available to the exoplanet research community. This award is part of NASA's Exoplanets Research Program and is not associated with the agency's Habitable Worlds Program. No set-aside designation was used for this contract.
