NASA/GSFC intends to extend the Magnetospheric MultiScale (MMS) mission contract with Southwest Research Institute (SwRI) on a sole-source basis for instrument and science operations. The estimated one-year performance period is from October 1, 2026, through September 30, 2027, under a cost-plus-fixed-fee contract. Services will be performed at SwRI and its subcontractor locations, including the Science Data Center at the University of Colorado in Boulder. SwRI is deemed the only qualified source due to its unique expertise, proprietary software, and decade-long operational history, making a transition risky to mission continuity. No budget amount is specified, and interested parties may submit capabilities for evaluation.
