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 one flight and one spare XRIS instrument, which will measure solar radiation energy to detect solar activity changes, such as solar flares, and support space weather predictions critical for protecting national infrastructure. The anticipated contract, valued as a Firm Fixed Price (FFP) hardware contract, is expected to span approximately eight years, with the first flight model due by June 2029 and the second by December 2029. 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 subsequent timelines.
