Solicitation description
Amendment 1: August 25, 2026 The SPARC Sources Sought Notice is hereby amended to add the List of Respondents as a posting attachment. Original Posting: August 3, 2026 The National Aeronautics and Space Administration (NASA) is hereby soliciting information from potential sources for the Space Power and Reactor Capabilities (SPARC) Contract. NASA is seeking capability statements from all interested parties, including all socioeconomic categories of Small Businesses (SB) and Historically Black Colleges and Universities (HBCUs)/Minority Institutions (MIs) for the purposes of determining the appropriate level of competition and/or small business subcontracting goals for the SPARC Contract and the Lunar Reactor 1 (LR-1) Phase 1 Task Order(s) which are expected to be awarded concurrently. The Government reserves the right to consider a Small, 8(a), Women-owned (WOSB), Service-Disabled Veteran (SD-VOSB), Economically Disadvantaged Women-owned Small Business (EDWOSB) or HUBZone business set-aside based on responses received. Respondents are requested to provide informed input on realistic and appropriate SB subcontracting and/or participation goals for the specific requirement. This type of feedback supports NASA’s market research and helps ensure the acquisition strategy is aligned with actual industry capability. Industry feedback is requested for: 1. SB Subcontracting goals; 2. Barriers that may limit SB participation, such as certifications, unique technical requirements, security needs, specialized tools, or high-risk performance areas and/or 3. Strategies to increase SB participation, including: Identifying areas appropriate for subcontracting Considering teaming or mentor protégé approaches NASA intends to pursue the solicitation of a Multiple Award Indefinite Delivery/Indefinite Quantity (MAIDIQ) contract to develop nuclear systems for use in space and on the lunar surface. This contract may include the delivery of technology development hardware and software, space flight hardware and software, ground support equipment, spares, operational support and research data. NASA is specifically seeking companies capable of functioning as a developer and prime integrator of space-nuclear systems. As such, the contractor(s) may be responsible for the definition, design, development, analysis, fabrication, assembly, test, verification, delivery, and/or operation of space systems, associated support systems and equipment, and related ground development activities, that include research and technology developments, supporting NASA missions. A copy of the Draft Statement of Work (SOW) is attached. Within the MAIDIQ solicitation, NASA currently intends to include acquisition materials and evaluation criteria sufficient to award the Lunar Reactor 1 (LR-1) Phase 1 Task Order(s) at the same time as the overarching MAIDIQ contract. LR-1 Phase 1 tentatively includes research and development from current state to Preliminary Design Review (PDR) level maturity....
