Space weather Observations at L1 to Advance Readiness (SOLAR) Series X-ray Irradiance Sensor (XRIS)
NASA Goddard Space Flight Center is seeking proposals for the SOLAR X-ray Irradiance Sensor (XRIS) acquisition. This requirement covers the design, development, fabrication, testing, and delivery of two flight-qualified sensors and one Engineering Development Unit for the Space Weather Next Program. The hardware is intended for operation at the L1 Lagrange point. The contract structure includes four CLINs using both Firm-Fixed-Price and Time-and-Materials arrangements. The first flight model is due in 2029 and the second in 2030, with post-production support options extending through 2037. Proposals must be submitted through NASA's EFSS Box by July 6, 2026. The solicitation includes technical specifications for Class C payloads, radiation hardness requirements, and a contract deliverables list. Offerors must submit volumes for technical approach, cost, past performance, and financial capability. The contract uses a mix of Firm-Fixed-Price (FFP) and Time-and-Materials (T&M) CLINs. CLINs 001 and 002 cover flight instruments and support on an FFP basis, while CLIN 004 uses T&M for engineering analysis. Hardware must meet strict radiation hardness standards for the L1 environment, including thresholds for Total Ionizing Dose and Single Event Effects.
