NASA SBIR/STTR Program Solicitation Details | 1. Program Description

1. Program Description

1.1 Legislative Authority and Background

The SBIR and STTR Extension Act of 2022 (Pub. L. 117-183.) amended the Small Business Act (15 U.S.C. 638) to extend the SBIR/STTR programs until September 30, 2025. Policy is provided by the Small Business Administration (SBA) through the combined Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs Policy Directive. The main purpose of the legislation is to stimulate technological innovation in the federal research/research and development (R/R&D) sector and increase private sector commercialization in both the SBIR and STTR programs. Accordingly, the NASA SBIR program is in a unique position to meet both goals by transforming scientific discovery and innovation to be used in NASA programs and missions as well as emphasizing private sector commercialization.

The SBIR program is Congressionally mandated and intended to support scientific excellence and technological innovation through the investment of Federal research funds to build a strong national economy by stimulating technological innovation in the private sector; strengthening the role of small businesses in meeting federal research and development needs; increasing the commercial application of federally supported research results; and fostering and encouraging participation by socially and economically disadvantaged and women-owned small businesses.

1.1.1 Due Diligence Program to Assess Security Risks

The SBIR and STTR Extension Act of 2022 requires NASA, in coordination with the SBA, to establish and implement a due diligence program to assess security risks presented by offerors seeking a Federally funded award. As noted above, the NASA SBIR/STTR Programs follow the policies and practices of the SBA SBIR/STTR Policy Directive. Revisions to the Policy Directive are in effect as of May 3, 2023 and the Federal Register Notice is available at: This revision is incorporated into this solicitation, including Appendix III, “Disclosures of Foreign Affiliations or Relationships to Foreign Countries” as reflected in the Disclosures of Foreign Affiliations or Relationships to Foreign Countries form (see section 2.3.1).

In accordance with Section 4 of the SBIR and STTR Extension Act of 2022, NASA will review all proposals submitted in response to this solicitation to assess security risks presented by offerors seeking an SBIR or STTR award. NASA will use the information provided by the offeror in response to the Disclosures of Foreign Affiliations or Relationships to Foreign Countries form and the proposal to conduct a risk-based due diligence review on the cybersecurity practices, patent analysis, employee analysis, and foreign ownership of a small business concern, including the financial ties and obligations (which shall include surety, equity, and debt obligations) of the offeror and its employees to a foreign country, foreign person, or foreign entity. NASA will also assess proposals utilizing open-source analysis and analytical tools, for the nondisclosures of the information set forth in 15 U.S.C. § 638 (9)(g)(17).


1.2 Purpose and Priorities

The purpose of Phase II is to continue the R/R&D developed under Phase I with a goal to commercialize and bring the innovation to either Federal or commercial markets, or both, as the Phase II project is completed. Phase II will require a more comprehensive proposal, outlining the effort in detail and the commercialization strategy for the effort. NASA recognizes that Phase II awards may not be sufficient in either dollars or time for the firm to complete the total R/R&D and the commercialization activities required to bring the project results to the marketplace. Therefore, completion of the research under these circumstances may have to be carried into Post Phase II opportunities or Phase III.

This solicitation includes instructions for small business concerns (SBCs) to submit a complete Phase II proposal package to the NASA SBIR program. Furthermore, program background information, eligibility requirements for participants, and information on the three program phases are contained herein. The 2023 Phase II solicitation period for submission of complete proposal packages begins on December 18, 2023, and ends at 5 p.m. Eastern Time on February 2, 2024.

The Space Technology Mission Directorate (STMD) provides overall policy direction for the implementation of the NASA SBIR program. The NASA SBIR/STTR Program Management Office (PMO), hosted at the NASA Ames Research Center, operates the program in conjunction with NASA mission directorates and centers. Additionally, the NASA Shared Services Center (NSSC) provides the overall procurement management for the programs. 

For this Phase II solicitation, NASA research and technology areas that were solicited at Phase I serve as the basis for the Phase II proposal. Under this solicitation, there will not be a listing of research topics/subtopics. Offerors are expected to provide proposals that are follow-on work from their 2023 Phase I award and should reference Chapter 9 of the Fiscal Year 2023 SBIR Phase I Solicitation for original subtopic information at


1.3 Three-Phase Program

The NASA SBIR program is carried out in three separate phases. Only Phase II and future opportunities are described below as offerors will have already completed Phase I to submit under this solicitation. The three phases are described in detail on the NASA SBIR/STTR website:

Phase II

Phase II proposals continue the R/R&D developed under Phase I to bring the innovation closer to transition into a NASA program or mission and/or commercialization of the innovation in the marketplace. Phase II will require a more comprehensive proposal, outlining the proposed effort in detail and the commercialization strategy for the effort. Only firms with FY2023 Phase I awards are eligible to submit a Phase II proposal at the conclusion of that Phase I contract.

Phase II Contracts


Maximum Contract Value


Maximum Period of Performance

24 months


Post-Phase II Opportunities for Continued Technology Development

NASA recognizes that Phase I and II awards may not be sufficient in either dollars or time for the firm to complete the total R/R&D and the commercialization activities required to make the project ready for transition into NASA or the commercial marketplace. Therefore, NASA has several initiatives for supporting its small business partners beyond their Phase I and Phase II awards.

Please refer to for Post Phase II eligibility, application deadlines, matching requirements, and further information.

Phase III

Phase III is the commercialization of innovative technologies, products, and services resulting from either a Phase I or Phase II contract. This includes further development of technologies for transition into NASA programs, other Government agencies, or the private sector. Phase III contracts are funded from sources other than the SBIR program and may be awarded without further competition.

Please refer to for Phase III information.


1.4 Availability of Funds

There is no commitment by NASA to fund any proposal or to make a specific number of awards and NASA may elect to make several or no awards in any specific research subtopic. The number of awards will be based on the level of appropriated funding provided to the program in FY 2024. Since this solicitation may be released prior to the passage of an appropriations act for FY 2024, enactment of continuing resolutions or an appropriations act may affect the availability or level of funding for this program and may delay the start date of Phase II contracts or impact the maximum contract value levels.


1.5 Eligibility Requirements

A description of any technical and business assistance obtained under this section, Section 3.4.15, and the benefits and results of the technical or business assistance provided will be a required deliverable of your contract.


1.8 Phase II Intern Diversity Supplement (IDS) Program

Offerors that are successful in receiving a Phase II award are eligible to apply for an intern diversity supplement to be effective only in the summer months of the second year of their Phase II project period. Instructions for requesting a diversity supplement will be provided directly to Phase II awardees prior to the application period.


The purpose of a Phase II intern diversity supplement is to improve the diversity of the research workforce by recruiting and supporting undergraduate and graduate students from groups that have been shown to be underrepresented in the U.S. science and engineering workforce.

Fostering diversity by encouraging the participation of individuals from nationally underrepresented groups in the scientific and engineering research workforce is a longstanding interest of Congress, and a key component of the NASA SBIR/STTR outreach strategy to identify, develop, support, and maintain the quality of its scientific and engineering workforce. Similarly, fostering and encouraging participation from women, socially and economically disadvantaged individuals, and other individuals in nationally underrepresented groups in the science and engineering workforce are equally critical to the success of the SBIR and STTR programs. Scientists, engineers, and entrepreneurs from underrepresented backgrounds and life experiences bring different perspectives, creativity, and individual enterprise to address complex scientific problems.

This diversity supplement is designed to provide support for research and entrepreneurial experiences for candidates whose participation will improve the SBIR/STTR program by promoting diversity in the small business community throughout the continuum from undergraduate to graduate level. Continuation of this program in the future will depend on evaluation of the career outcomes of the supported individuals as well as continuing assessments of the diversity of the small business programs by the U.S. Small Business Administration and the National Academies.

In all cases, the proposed research experience must be an integral part of the approved ongoing research of the eligible NASA Phase II award and must have the potential to contribute to the research and entrepreneurial career development of the candidates.


SBCs are encouraged to identify women, individuals from nationally underrepresented groups, individuals with a commitment to diversifying the science and engineering workforce, and/or individuals meeting the SBA definition of socially and economically disadvantaged.

Members of socially disadvantaged groups as defined by Executive Order on Advancing Racial Equity and Support for Underserved Communities Through the Federal Government dated January 20, 2021, are:

  • Black, Latino, Indigenous, and Native American persons, Asian Americans and Pacific Islanders and other persons of color; members of religious minorities; lesbian, gay, bisexual, transgender, and queer (LGBTQ+) persons; persons with disabilities; persons who live in rural areas; and persons otherwise adversely affected by persistent poverty or inequality Black Americans.

An economically disadvantaged individual candidate for a diversity supplement must have:

  • a net worth less than $750,000 (not including his or her primary residence and the value of the individual’s ownership interest in a socially and economically disadvantaged SBC, if any),
  • an average adjusted gross income of $350,000 or less for the preceding three years, and
  • the fair market value of all his or her assets (including his or her primary residence and the value of the individual’s ownership interest in a socially and economically disadvantaged SBC, if any) does not exceed $6 million.

For purposes of the diversity supplement, the definitions above apply to the individual candidates, not the SBC Phase II offeror applying for the supplement.

As part of this supplement program, Undergraduate, Baccalaureate, and Master's Degree and Graduate students who have a demonstrated interest in or desire to pursue science, technology, engineering, or math (STEM) training and entrepreneurship, may participate in a Phase II research project during the summer months. This experience is separate from any requirement of the regular academic program.

The duration of the program is normally 10 weeks but could be extended with a no-cost extension request and approval from the Contracting Officer. This supplement program is limited to citizens or non-citizen nationals of the United States or individuals who have been lawfully admitted for permanent residence in the United States.
