About this opportunity
NASA Headquarters has published a Special Notice seeking submissions for mission partnerships to support the continued operations of three Earth science instruments hosted on the International Space Station through the end of its planned lifetime in fiscal year 2030. The three missions are the Climate Absolute Radiance and Refractivity Observatory (CLARREO) Pathfinder (CPF), Orbiting Carbon Observatory-3 (OCO-3), and Stratospheric Aerosol and Gas Experiment (SAGE) III. These instruments collect critical data on Earth's climate and atmospheric conditions, including measurements of sunlight reflection for calibration standards, atmospheric carbon dioxide characterization, and stratospheric ozone and aerosol observations. NASA is actively seeking collaborative partnerships to support mission operations, science data collection and processing, and data product availability through the ISS program. This Special Notice represents an opportunity for organizations to engage in space research and development activities aligned with NASA's Earth science objectives.
NASA's objective in issuing this Special Notice is to establish operational partnerships with organizations capable of managing or contributing to the continued operations and data management of these three Earth science missions. The current proposal deadline has been extended to December 12, 2025 at 11:59 p.m. Central Time, with technical questions due by November 25, 2025. NASA is open to various partnership arrangements, including full or partial use of existing mission operations teams, consortiums, and multiple partnerships per mission, with a stated preference for arrangements that maintain broad and open access to data products for the research and applications communities. There are no specific set-aside requirements, and eligible participants can include individual organizations or consortia from any sector capable of supporting space research and development activities, classified under NAICS code 54171 (Research and Development in Physical, Engineering, and Life Sciences). All submissions must be made through the NSPIRES system, and interested parties are encouraged to submit questions and review guidance materials available in the solicitation attachments.

NASA is seeking submissions under the Research Opportunities for International Space Station Utilization Earth Mission Partnerships focus area for partnerships for the continued operations of the Earth science missions identified below through the end of ISS lifetime, which is currently planned for decommissioning at the end of fiscal year 2030.
Missions:
- CPF (https://clarreo-pathfinder.larc.nasa.gov/): Climate Absolute Radiance and Refractivity Observatory (CLARREO) Pathfinder (CPF) instrument will measure sunlight reflected by the Earth and Moon with up to ten times better accuracy than current sensors, serving as a calibration standard for Earth observation instruments, including commercial data providers, to improve accuracy. CPF is designed to be hosted on ISS. Per the FY26 PBR Technical Supplement, NASA is seeking partnerships for CPF operations if NASA deploys it to the ISS in 2026 and it is manifested through the end of the ISS lifetime.
- OCO-3 (https://ocov3.jpl.nasa.gov/): Orbiting Carbon Observatory-3 collects space-based measurements of atmospheric carbon dioxide to characterize its sources and sinks and quantify their variability over the seasonal cycle. OCO-3 was launched and began collecting data in 2019. OCO-3 is externally mounted on the Japanese Experiment Module-Exposed Facility (JEM-EF) Site 3 on the ISS. OCO-3 is currently manifested in this site through the end of ISS lifetime.
- SAGE III (https://sage.nasa.gov/missions/about-sage-iii-on-iss/): Stratospheric Aerosol and Gas Experiment (SAGE) III observes stratospheric ozone, aerosols, and water vapor from space. Using an occultation technique, SAGE uses the light that passes through the atmosphere when the sun and moon rise and set to measure gases and particles in that region of the atmosphere. SAGE III was launched and began collecting data in 2017. SAGE III is externally mounted on the EXPRESS Logistics Carrier (ELC) 4 on the ISS. SAGE III is currently manifested in this site through the end of ISS lifetime
As part of partnerships for one of more of these missions, NASA is interested in the proposed arrangements regarding the mission operations; science data collection, processing, and archiving; calibration efforts; science data availability, latency, and access; ground systems; and other aspects. NASA is open to all proposals and novel ideas for productive arrangements, including full to partial use of existing mission operations teams via reimbursable terms. In addition, NASA will consider partnerships with a consortium involving multiple interested organizations as well as multiple partnerships for each mission. NASA’s preference is that, to the maximum extent possible, a partnership would continue some to all of the data products and make them broadly and openly available to the research and applications communities.
NASA is currently accepting white papers through August 29, 2025 at 11:59pm central time. Additional details can be found in Focus Area 2 and Attachment M. Technical questions can be submitted via email to the ISS NASA Research Announcement (NRA) Manager (Colleen Corbett, colleen.corbett@nasa.gov) and the Earth Science Division mailbox

- SAGE III (https://sage.nasa.gov/missions/about-sage-iii-on-iss/): Stratospheric Aerosol and Gas Experiment (SAGE) III observes stratospheric ozone, aerosols, and water vapor from space. Using an occultation technique, SAGE uses the light that passes through the atmosphere when the sun and moon rise and set to measure gases and particles in that region of the atmosphere. SAGE III was launched and began collecting data in 2017. SAGE III is externally mounted on the EXPRESS Logistics Carrier (ELC) 4 on the ISS. SAGE III is currently manifested in this site through the end of ISS lifetime
As part of partnerships for one of more of these missions, NASA is interested in the proposed arrangements regarding the mission operations; science data collection, processing, and archiving; calibration efforts; science data availability, latency, and access; ground systems; and other aspects. NASA is open to all proposals and novel ideas for productive arrangements, including full to partial use of existing mission operations teams via reimbursable terms. In addition, NASA will consider partnerships with a consortium involving multiple interested organizations as well as multiple partnerships for each mission. NASA’s preference is that, to the maximum extent possible, a partnership would continue some to all of the data products and make them broadly and openly available to the research and applications communities.
NASA is currently accepting white papers through August 29, 2025 at 11:59pm central time. Additional details can be found in Focus Area 2 and Attachment M. Technical questions can be submitted via email to the ISS NASA Research Announcement (NRA) Manager (Colleen Corbett, colleen.corbett@nasa.gov) and the Earth Science Division mailbox
(hq-esdpartnerships@mail.nasa.gov) before August 19, 2025 at 11:59 central time.
