Quick Summary

NASA Goddard Space Flight Center (GSFC) has issued a Draft Request for Proposal (RFP) for the Space weather Observations at L1 to Advance Readiness (SOLAR) Series X-ray Irradiance Sensor (XRIS). This is not a request for proposals, but an opportunity for interested parties to provide comments on the draft solicitation. The primary objective is to design, analyze, develop, and fabricate two flight X-Ray Irradiance Sensors to monitor X-ray flares impacting Earth's ionosphere. Comments on the Draft RFP are due by February 18, 2026, 5:00 PM ET. This acquisition will be conducted as a full and open competition.

Purpose and Scope

The principal purpose of this requirement is to develop two flight X-Ray Irradiance Sensors (XRIS), designated FM-1 and FM-2, for the joint NASA/NOAA SOLAR Series Mission. These sensors are critical for monitoring X-ray flares that cause changes in Earth's ionosphere, supporting space weather predictions. The scope of work includes:

  • Design, analysis, development, and fabrication of two flight XRIS units.
  • Integration, testing, calibration, evaluation, and support for launch and on-orbit check-out.
  • Supply and maintenance of instrument Ground Support Equipment (GSE).
  • Development of Ground Processing Algorithms (GPAs) and support for the Mission Operations Center (MOC).
  • Post-delivery support for integration, launch, calibration, data validation, operational handover, and anomaly investigations.

Contract Details

  • Type: Hybrid Firm Fixed Price (FFP) and Time & Materials (T&M) contract.
  • Contract Line Items (CLINs):
    • CLIN 001: Flight Instrument (FFP) – includes XRIS FM-1, FM-2, Engineering Development Unit (EDU), spares, and various ground support systems.
    • CLIN 002: Post Delivery Support (FFP).
    • CLIN 003: Special Studies (T&M, with a ceiling price of $350,000).
  • Period of Performance: Approximately eight years, from contract award through January 2034 (or 15 months after SOLAR-B launch, targeted October 2032).
  • Key Deliveries: First flight unit (FM-1) by November 2029; second flight unit (FM-2) by May 2030.
  • Place of Performance: Offsite at the Contractor's facilities.
  • Set-Aside: Full and Open Competition.
  • NAICS: 336414 (Aircraft Manufacturing), with a small business size standard of 1,300 employees.
  • Product Service Code: AR15 (Space R&D Svcs).

Submission & Evaluation

  • Draft RFP Comments Due: February 18, 2026, 5:00 PM ET. Submit electronically via email to Daniel Han (Daniel.S.Han@nasa.gov), referencing XRIS-DRFP-80GSFC26R7004.
  • Final RFP Release: Anticipated early Q2 2026, with proposals due approximately 30 calendar days after release.
  • Contract Award: Anticipated Q4 2026.
  • Evaluation Factors (for final RFP): Mission Suitability (numerically scored), Cost, and Past Performance.
  • Required Submissions (for final RFP): Funding Profile, Safety and Health Plan, Small Business Subcontracting Plan, Time-and-Materials Rates, Contractor Proposed Enhancements, Quality Assurance Plan, Financial Capability Disclosure, and Past Performance Questionnaire.
  • Post-Award Requirements: Information System Security Plan and Organizational Conflicts of Interest (OCI) Avoidance Plan required within 30 days of contract effective date.
