Sustainable Land Imaging (SLI) Mission Alternatives Assessment Team (MAAT): Request for Information (RFI)

This Special Notice from NASA Headquarters publishes a Request for Information (RFI) for the Sustainable Land Imaging (SLI) Mission Alternatives Assessment Team (MAAT). The RFI seeks innovative solutions to continue the Landsat satellite program's legacy of global land surface imaging with a more affordable mission architecture. NASA has published the complete RFI documentation along with supporting materials, including an initial email notification sent to Science Mission Directorate subscribers and a Frequently Asked Questions document added through Amendment #1. The agency may periodically update the notice with additional documents or revisions to the RFI. All questions and comments must be submitted via email with the subject line including "SLI MAAT RFI."

The primary objective is to identify cost-effective alternatives for continuing Landsat's earth observation mission with target availability by 2031 and minimum five-year operational capability. NASA anticipates funding of $70-130.2 million annually from FY26-FY30 and is exploring various solution approaches including all-commercial options, hybrid government-commercial arrangements, and service-level agreements. Responses are due August 29, 2025, at 11:59 PM EDT and must be submitted as 5-page presentations addressing technical concepts, schedules, costs, and risk management. Participation is restricted to U.S. entities organized under U.S. laws and more than 50% owned by U.S. nationals, including industry, universities, non-profit organizations, NASA centers, and other U.S. government agencies. International team members are permitted only as part of U.S.-led science teams, and all participants must comply with restrictions prohibiting bilateral relationships with China under SEC. 526 of the Consolidated Appropriations Act.
