ROSES 2025: B.10 Heliophysics Flight Opportunities Studies

The National Aeronautics and Space Administration (NASA) has announced the Research Opportunities in Space and Earth Sciences (ROSES) 2025 solicitation, specifically the B.10 Heliophysics Flight Opportunities Studies (HFOS) program. This funding opportunity falls under the NASA Science Mission Directorate (SMD) and is part of the broader annual omnibus research announcement, which includes various program elements across multiple science divisions. The primary goal of HFOS is to support research and development in heliophysics by providing funding for flight opportunities that enhance the understanding of solar and space physics.

The program seeks proposals from researchers affiliated with U.S. institutions, with limited exceptions for international organizations that meet specific non-exchange-of-funds requirements outlined in the NASA Proposer’s Guide. Funding will be awarded primarily in the form of grants and cooperative agreements, with contracts being generally excluded due to the nature of the work solicited. The solicitation covers both basic and applied research in support of NASA's heliophysics objectives.

The HFOS opportunity is part of the broader ROSES-2025 initiative, which includes multiple research topics and deadlines. Proposals must be submitted in accordance with the guidelines provided in the ROSES-2025 solicitation documents. Applicants are required to retrieve the necessary instructions and forms from NASA’s online systems, including NSPIRES, to ensure compliance with submission requirements. Specific details on the HFOS program element can be accessed through NASA’s solicitation web pages.

While the estimated total program funding has not been specified, the opportunity does not require cost-sharing or matching funds. The typical performance period for an award under ROSES is three years, with some variations allowing for shorter or longer durations up to five years. Applicants should be aware that each program element within ROSES has individual due dates and requirements, which are detailed in Tables 2 and 3 of the solicitation.

The submission deadline for the HFOS program is August 27, 2025. NASA strongly encourages interested applicants to review the full announcement, retrieve the necessary proposal documents, and consult the Proposer’s Guide for eligibility and submission details. Further inquiries can be directed to the designated program contact at NASA Headquarters.

For additional questions regarding ROSES-2025, applicants may refer to the frequently asked questions (FAQs) section provided by NASA or contact the Office of the SMD Deputy Associate Administrator for Research via email at sara@nasa.gov. Specific inquiries related to the HFOS program element should be addressed to Dr. Roshanak Hakimzadeh at NASA Headquarters.
