Appendix 26B: Small Business Technology Transfer (STTR) Phase I Funding Opportunity

The NASA FY 26‑27 SBIR/STTR solicitation (Appendix 26B‑I) seeks Phase I proposals that define a physical‑science research capability—specifically in combustion, fluid physics, or soft‑matter—and develop a prototype test‑facility design for use on a Commercial Low‑Earth‑Orbit Destination (CLD), a lunar lander (including CLPS), the Lunar Gateway, a free‑flyer, Artemis, or the ISS. Offerors must present a clear work plan with success criteria, performance and simulation models, CAD designs, and validated protocols, and must include a preliminary business case (cost/revenue forecast, market size, potential customers, and commercialization strategy). Phase II will require a preliminary design and concept of operations, development and testing of an engineering‑development unit in a relevant ground or space environment, detailed interface and performance specifications, test results, and an updated business‑case analysis with identified partners; concepts capable of sub‑orbital or ISS flight demonstration are especially valued. Proposals are limited to one unique innovation per subtopic, with a maximum of two submissions per offeror and no substantially equivalent proposals across subtopics. All submissions must be electronic, comply with the listed FAR/NFS clauses (including data‑rights, security, and buy‑American requirements), and include any existing or projected funding commitments beyond Phase I/II. Evaluation will focus on work‑plan effectiveness, commercial potential, and alignment with the target platforms, with Phase I deliverables such as performance models, CAD files, and validated workflows, and Phase II deliverables including a test article, test design, and detailed reporting. The Help Desk will respond to questions only through May 20 2026, 5:00 PM ET.
