REQUEST FOR INFORMATION (RFI) Title: Request for Information - Space Weather Next Program - Partner Contributed Instrument (PCI) Capabilities for the Space Weather Observations at L1 to Advance Readiness (SOLAR)-B Mission Date of Original Posting: May 26th, 2026 RFI Responses Due by: June 21, 2026, 11:59 PM ET 1.0 Introduction 1.1 Purpose of this RFI This RFI is issued by the National Oceanic and Atmospheric Administration (NOAA) to request information from all sources (including government entities, commercial firms, and non-profit organizations) with the capability to offer a Partner Contributed Instrument (PCI) to be hosted aboard the NOAA Space Weather Next Program's SOLAR-B mission. NOAA may host one PCI that best complements the SOLAR-B mission's primary observations, demonstrates a compelling Research to Operations (R2O) case for advancing space weather observation, adheres to the specified size, weight, and power limits, meets the project schedule, is technically feasible and compatible with the SOLAR-B spacecraft within the specified "do no harm" requirements, and is supported by a robust financial and programmatic commitment from the submitting organization. Organizations that intend to or are likely to provide a PCI are invited to respond to this RFI. 1.2 The NOAA Space Weather Next Program and SOLAR-B Mission Overview Space weather refers to those conditions in the space environment that may be damaging to technological systems deployed in space or on the ground and to humans in space. The NOAA Space Weather Observations (SWO) office vision is "a space weather ready nation," with a mission to “provide trusted space weather observations to safeguard society." This vision and mission are directly responsive to the legislative mandate of the Promoting Research and Observations of Space Weather to Improve the Forecasting of Tomorrow (PROSWIFT) Act of 2020. Specifically, the PROSWIFT Act mandates that NOAA shall "support competitive, peer-reviewed proposals for [..] monitoring of space weather and its impacts" and shall facilitate "research to operations and operations to research." NOAA is implementing this mission through the SWO Space Weather Next (SW Next) Program with acquisition assistance from the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC). The SW Next Program's goal is to provide critical data to its primary customer, the National Weather Service's (NWS) Space Weather Prediction Center (SWPC) to support its mission of ”safeguarding society with actionable space weather information.” The Space weather Observations at L1 to Advance Readiness (SOLAR) project ensures continuous, high availability, and low latency space weather observations from the first Sun-Earth Lagrange point (L1). These measurements of the space environment and the Sun's outer atmosphere (corona) are critical for accurate space weather forecasts. The SOLAR project maintains observational continuity of real-time solar im…
