The National Aeronautics and Space Administration (NASA) is preparing to issue a Draft Request for Proposal (RFP) for the Space Weather Observations at Lagrange 1 (SOL) X-ray Irradiance Sensor (XRIS) instrument, in collaboration with the National Oceanic and Atmospheric Administration (NOAA). This procurement aims to design, develop, and fabricate two XRIS instruments that will monitor solar activity, providing critical data for predicting solar energetic particle events and their potential impacts on Earth's infrastructure, including aviation and satellite communications. The anticipated contract, expected to be awarded in January 2026, will follow a full and open competition, with a performance period extending through January 2034. Interested parties should direct inquiries to Suzanne Sierra at suzanne.k.sierra@nasa.gov, and monitor the NASA procurement website for updates on the Draft RFP and submission timelines.
