- The National Science Foundation Division of Astronomical Sciences awarded a $421,796 Project Grant to Arizona State University to conduct collaborative research on revealing exoplanet atmospheres using high-resolution spectroscopy. The 3-year grant, starting September 1, 2023, will support a team led by the University of Chicago and Arizona State University to study the atmospheres of close-in giant planets orbiting distant stars. The research aims to address four key science questions related...
- The National Science Foundation Division of Atmospheric and Geospace Sciences awarded a $199,628 Project Grant to Texas A&M University to develop a robust light-scattering computational capability based on the method of separation of variables in spheroidal coordinates for small-to-large spheroids. The award period runs from December 1, 2021 through November 30, 2023. The work will be conducted under the NSF's Geosciences program (CFDA #47.050), which supports basic research in the...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $399,934 to Bates College to develop a low-temperature spectroscopy facility. The goal is to improve spectroscopic models used in remote sensing instruments, which currently have biases that limit their ability to accurately measure atmospheric methane. The project will leverage specialized equipment at Bates College and the University of Colorado Boulder to conduct reference spectroscopy...
The National Science Foundation Division of Astronomical Sciences awarded Spectral Sciences, Inc. $530,973 on August 1, 2026, under the Mathematical and Physical Sciences program to conduct ground-based observations of Titan's atmospheric methane and develop radiative transfer modeling software. Spectral Sciences will determine the amount and distribution of methane in Titan's atmosphere over seasonal timescales by leveraging ground-based observational capabilities. The work will characterize methane's role in Titan's hydrologic cycle—the only active methane-based hydrologic cycle outside Earth in the solar system—and provide constraints on photochemical, hydrologic, and geologic processes. The project includes updating the PYDISORT radiative transfer code to allow variable atmospheric methane profiles and deriving near-surface humidity assessments. Spectral Sciences will develop a user-friendly graphical user interface to introduce undergraduate students and next-generation scientists to radiative transfer physics and planetary science research methods. Performance occurs in Burlington, Massachusetts, with a period of performance through July 31, 2029. The award is classified as a Project Grant. Spectral Sciences, a small business headquartered in Burlington, specializes in advanced research and development for space and scientific applications, with prior NASA grants for Titan atmospheric modeling and a substantial portfolio of federal research awards across defense and civilian agencies.
