<p><em><strong><u>Amendment 1 (October 28, 2026)</u></strong></em></p>

<p>This posting is hereby amended to correct the title from &quot;Space Power and Reactor Capabilities (SPARC) - Sources Sought Notice&quot; to &quot;Space Power and Reactor Capabilities (SPARC) - Presolicitation Synopsis&quot;.</p>

<p></p>

<p><em><strong><u>Original Posting (October 27, 2026)</u></strong></em></p>

<p>NASA intends to issue the Space Power and Reactor Capabilities (SPARC) Final Request for Proposals (RFP) via sam.gov on or around November 20, 2026.</p>

<p>A Sources Sought Notice for SPARC was posted to sam.gov on August 3, 2026, entitled &quot;Space Power and Reactor<br />
Capabilities (SPARC) - Sources Sought Notice&quot; and under Notice ID 80GRC026SPARC.</p>

<p>A Draft RFP for SPARC was posted to sam.gov on August 30, 2026, entitled &quot; Space Power and Reactor Capabilities (SPARC) - Draft Request for Proposals (DRFP)&quot; and under Notice ID 80GRC026R0009. Interested parties are highly encouraged to review the Draft RFP posting for information regarding the acquisition including the Industry Day Presentation and Questions and Answers.</p>

<p>The Notice ID for the SPARC Final RFP is likely be updated due to it being released in Government Fiscal Year (GFY) 2027.</p>

<p>SPARC will be competed as a Multiple-Award Indefinite Delivery/Indefinite Quantity (MAIDIQ) contract to provide for the design, development, analysis, fabrication, assembly, verification, validation, test, evaluation, certification, delivery (ground and/or space), and sustaining maintenance and operations of space nuclear systems, subsystems, hardware, materials, and software. Specifically, SPARC is intended to be NASA&#39;s preferred contractual mechanism for the competition and award of task orders related to the Design, Deveopment, Test, and Evaluation (DDT&amp;E) of the Lunar Reactor - 1 (LR-1) system.</p>

<p>Concurrent with (and as part of) the competition and award of SPARC, NASA intends to compete the first task order to be awarded under SPARC in the LR-1 Phase 1 Task Order. This task order represents the first step in the development of LR-1 and provides for the following objectives:</p>

<ul>
<li>Objective 1. Develop a Preliminary Design Review (PDR) level design for LR-1 that achieves the defined requirements and ensures the technology readiness is sufficient to proceed to flight system development.&nbsp;&nbsp;</li>
<li>Objective 2. Perform an electrically-heated integrated system test in a relevant environment (as defined by the requirements) that incorporates representative versions of the key subsystems (an engineering test unit (ETU)).&nbsp;</li>
<li>Objective 3. Perform component-level radiation exposure testing to demonstrate the LR-1 design will operate as intended within the induced (reactor) and natural (Lunar surface) radiation environments.&nbsp;</li>
</ul>
