Space Technology Research, Development, Demonstration, and Infusion-2023 (SpaceTech-REDDI-2023)

Funding Agency:
National Aeronautics and Space Administration

This NASA Research Announcement (NRA), entitled “Space Technology Research,  Development, Demonstration, and Infusion-2023 (SpaceTech-REDDI-2023)” is the NASA Space Technology Mission Directorate (STMD) umbrella NRA solicitation.

The Space Technology Mission Directorate (STMD) is dedicated to developing transformative, cross-cutting technologies that enable NASA’s missions while also supporting commercial and other government agencies’ needs where appropriate. The Space Technology account supports the Administration's priorities of developing new technologies to enable human and robotic exploration of the Moon, Mars, and beyond and enhancing research and development to contribute to U.S. leadership in space technology. Through STMD, NASA invests in high-risk, high-reward activities across the technology development spectrum through partnerships with academia, entrepreneurs, and small and large businesses.  

Proposals for space technology research, development, and demonstration in support of STMD will be solicited through Appendices under this umbrella solicitation as technology topics are defined and funding is made available for new opportunities. See STMD solicitation URL for anticipated releases. Release of Appendices is subject to availability of appropriated funds and may change. Additional Appendices may be issued throughout the year as needed. 

Effective: October 1, 2022 – September 30, 2023

Areas of Interest

Early Stage Innovations (ESI23)

Notices of Intent Due: June 7, 2023 (5 PM Eastern)

Proposals Due: July 6, 2023 (5 PM Eastern, 2 PM Pacific) 

NASA’s Space Technology Mission Directorate (STMD) hereby solicits proposals from accredited U.S. universities for innovative, early-stage space technology research of high priority to NASA’s Mission Directorates. 

This specific Appendix is titled Early Stage Innovations (ESI) and is one of five calls for proposals from STMD’s Space Technology Research Grants (STRG) Program. Early Career Faculty (ECF), Space Technology Research Institutes (STRI), NASA Space Technology Graduate Research Opportunities (NSTGRO), and Lunar Surface Technology Research (LuSTR) Opportunities appear as Appendix B1, Appendix B3, Appendix B4, and Appendix B5, respectively, under the SpaceTech-REDDI NRA. 

This Appendix seeks proposals on specific space technologies that are currently at low Technology Readiness Levels (TRL). Investment in innovative low-TRL research increases knowledge and capabilities in response to new questions and requirements, stimulates innovation, and allows more creative solutions to problems constrained by schedule and budget. Moreover, it is investment in fundamental research activities that has historically benefited the Nation on a broader basis, generating new industries and spin-off applications. 

Our Nation’s universities couple fundamental research with education, encouraging a culture of innovation based on the discovery of knowledge. Universities are, therefore, ideally positioned to conduct fundamental space technology research and to diffuse newly found knowledge into society at large through graduate students and industry, government, and other partnerships. STMD investments in space technology research at U.S. universities promote the continued leadership of our universities as an international symbol of the country's scientific innovation, engineering creativity, and technological skill. These investments also create, fortify, and nurture the talent base of highly skilled engineers, scientists, and technologists to improve America’s technological and economic competitiveness. 

The ESI Appendix challenges universities to examine the theoretical feasibility of new ideas and approaches that are critical to making science, space travel, and exploration more effective, affordable, and sustainable. It is the intent of the STRG Program and this Early Stage Innovations opportunity to foster interactions between NASA and the awarded university Principal Investigators (PIs)/teams. Therefore, interaction with NASA researchers should be expected while conducting space technology research under these awards. 


NASA Innovative Advanced Concepts (NIAC) Phase I

Step A Proposals Due: June 28, 2023

This Appendix solicits proposals for studying visionary, yet credible, advanced concepts in the NASA Innovative Advanced Concepts (NIAC) Program.  NIAC’s goal is to “Change the Possible” in aerospace and aeronautics missions.  The NIAC Program supports innovative research through Phase I, Phase II, and Phase III awards.  This Appendix focuses only on Phase I proposal requirements and award information; future Appendices will be released for Phase II and Phase III opportunities. Proposers are advised that changes to this Appendix have been incorporated to clarify evaluation criteria and required proposal content. In addition, prospective proposers should review previously funded NIAC studies to ensure planned submissions are not duplicative of previously funded work. 

The NASA Innovative Advanced Concepts (NIAC) Program focuses on early-stage feasibility studies of visionary concepts that address national government and commercial aerospace goals.  Concepts are solicited from any field of study that offers a radically different approach or disruptive innovation that may significantly enhance or enable new human or robotic science and exploration missions. 

The NIAC Program supports innovative research through multiple phases of study.  Phase I awards are for efforts up to nine months funded at up to $175,000 per award to explore the overall feasibility and viability of visionary concepts.  Phase II awards are for efforts up to two years with total funding of up to $600,000 per award to further develop the most promising Phase I concepts, and to explore potential infusion options within and beyond NASA.  Concepts should be sufficiently well developed at the end of Phase II to seek follow on development funds from other NASA programs, external government programs, or commercial partners.  However, in rare instances there may be a compelling need for the strategic investment of additional NIAC funds to further advance Phase II concepts with clearly defined transition paths into other NASA, government, or commercial programs.  Phase III awards are designed to meet this need, with the anticipated selection of no more than one new award per year. Phase III studies will be funded for a maximum duration of two years at a total funding level of up to $2,000,000 per award.  NIAC will later release separate REsearch, Development, Demonstration, and Infusion (REDDI) NRA Appendices soliciting Phase II and Phase III proposals, respectively.  NIAC will allow sufficient time for eligible Phase I Fellows awarded in this solicitation to apply for Phase II follow-on support of up to two more years of study and development. 

Eligibility Requirements

To the greatest extent practicable, participation will be open to all categories of U.S. and non-U.S. organizations, including educational, industry, nonprofit institutions, Federally Funded Research and Development Centers (FFRDCs), University Affiliated Research Centers (UARCs), NASA Centers, the Jet Propulsion Laboratory (JPL), and other Government agencies. Historically Black Colleges and Universities (HBCUs), Minority Serving Institutions (MSIs), small disadvantaged businesses (SDBs), veteran-owned small businesses, service-disabled veteran-owned small businesses (SDVOSBs), HUBZone small businesses, and women-owned small businesses (WOSBs) are encouraged to apply. Individual Appendices may identify specific eligibility limitations that apply to that relevant opportunity. 

Unless Appendices specify additional information or provide limitations on the number of proposals that may be submitted by an organization, there is no restriction on the number of proposals that an organization may submit in response to an Appendix or on teaming arrangements for any one proposal. Each proposal must be a separate, standalone, complete document for evaluation purposes.
