The NSF Major Research Instrumentation (MRI) Program supports the acquisition or development of shared scientific and engineering instrumentation that is essential to advancing research capabilities at U.S. institutions. Unlike traditional NSF research grants, MRI awards focus exclusively on equipment and technical infrastructure—not on the research projects themselves. MRI proposals may request support to acquire advanced instruments such as high-resolution imaging systems, next-generation microscopes, mass spectrometers, genome sequencers, sensor networks, high-performance computing clusters, or observatory components. The program also funds instrument development, enabling teams to design and build cutting-edge systems that are not commercially available. 

MRI emphasizes broad scientific impact and shared institutional use. Instrumentation must serve multiple users, departments, or research communities and significantly enhance the institution’s research capacity. Proposals must include detailed technical specifications, management plans, data-sharing strategy, and documentation of institutional commitment. Cost sharing is required for Phases 1 and 2, with institutions typically contributing 30% of total project costs unless exempt. Awards are typically categorized as: 
• Track 1: $100,000 to $1 million 
• Track 2: $1 million to $4 million 
• Track 3: development of next-generation instrumentation, up to $4 million 

Eligibility includes U.S. institutions of higher education, museums, research nonprofits, and certain independent research organizations. For-profit entities cannot serve as the lead but may participate as collaborators or vendors. Small businesses often play key roles in fabrication, hardware integration, software systems, or technical services. Successful proposals must demonstrate institutional need, technical feasibility, broad community benefit, and long-term sustainability of the instrument.
