This RFI from NOAA seeks information on Partner Contributed Instruments (PCI) for the SOLAR-B mission, which will provide operational resiliency and extend space weather observations from the first Sun-Earth Lagrange point (L1). The SOLAR-B observatory is designed for five years of operation with propellant for an additional five years, and its PCI represents a "next generation" opportunity to advance research-to-operations goals. No specific budget amounts are mentioned in the description. The location for performance of services is the L1 Lagrange point. Responses to this RFI are due by June 21, 2026, at 11:59 PM ET.

This RFI from NOAA seeks information on Partner Contributed Instruments (PCI) for the SOLAR-B mission, which will provide operational resiliency and extend space weather observations from the first Sun-Earth Lagrange point (L1). The SOLAR-B observatory is designed for five years of operation with propellant for an additional five years, launching a few years after SOLAR-A (planned for fiscal year 2030). The selected PCI must complement primary observations, demonstrate a compelling Research to Operations case, and meet specified size, weight, and power limits. Submitting organizations must show robust financial and programmatic commitment, with responses due by June 21, 2026. Performance of services will be aboard the SOLAR-B spacecraft at L1.
