NASA SBIR/STTR Phase I Topics

Below is a brief summary. Please check the full solicitation before applying (link in resources section).

Executive Summary:

NASA is accepting proposals for its FY26–27 SBIR/STTR Phase I programs under Broad Agency Announcement (BAA) 80NSSC26R0003. The deadline to apply is May 21, 2026, by 5:00 PM ET.

This is a short application window and a highly structured opportunity. NASA will not evaluate late or incomplete submissions, and companies are limited to no more than two proposal packages.

The program funds early-stage R&D aligned with NASA’s defined technical needs across space systems, aeronautics, materials, energy, planetary science, and in-space infrastructure. Each proposal must target a single subtopic, and NASA will not move proposals between topics—fit matters.

For Phase I:

• Maximum funding: $225,000

• Project duration:

  • SBIR: up to six (6) months

  • STTR: up to thirteen (13) months

All submissions must be completed through NASA’s ProSAMS system, including all required forms, technical proposal components, and endorsements.

Companies that successfully complete Phase I may be invited to submit for Phase II follow-on funding, with additional development support and commercialization pathways.

This is a tightly scoped, compliance-heavy opportunity with defined technical gaps. If your technology aligns with a subtopic, you should move quickly to prepare a compliant submission before the May 21, 2026, by 5:00 PM ET deadline.

How much funding would I receive?

• Up to $225,000 per Phase I award

• Optional Technical and Business Assistance (TABA): up to $6,500 (if requested)
