Juno Propulsion Awarded Competitive Grant from the U.S. National Science Foundation — Juno Propulsion Juno Propulsion Awarded Competitive Grant from the U.S. National Science Foundation Written By Alexis Harroun SEATTLE, WA, September 11, 2024 – Juno Propulsion Inc. has been awarded a U.S. National Science Foundation (NSF) Small Business Innovation Research (SBIR) grant for $275,000 to conduct research and development (R&D) work on next-generation rocket propulsion using rotating detonation combustion.
Juno Propulsion is working to power the next decade of the space economy, rapidly growing to a projected $1T USD industry by 2030. Despite the strong demand for products and services offered by space providers, there remains a large barrier to accessing and operating in space, mainly due to outdated propulsion options.
Juno’s in-space propulsion solution is based on rotating detonation combustion, with improved fuel efficiency to enable endless mission opportunities. “NSF accelerates the translation of emerging technologies into transformative new products and services,” said Erwin Gianchandani, NSF Assistant Director for Technology, Innovation and Partnerships.
“We take great pride in funding deep-technology startups and small businesses that will shape science and engineering results into meaningful solutions for today and tomorrow. ” “Through the NSF SBIR, we are funding the next phase of our technology development and bringing our product closer to market” said Alexis Harroun, CEO and Founder of Juno Propulsion.
“This award is critical to advancing our goal of offering the first rotating detonation combustion-based thruster for use in space. ” All proposals submitted to the NSF SBIR/STTR program, also known as America’s Seed Fund powered by NSF, undergo a rigorous merit-based review process. Once a small business is awarded a Phase I grant, it becomes eligible to apply for Phase II funding and additional supplements totaling up to $2 million.
About the U.S. National Science Foundation's Small Business Programs: America’s Seed Fund powered by NSF awards more than $200 million annually to startups and small businesses, transforming scientific discovery into products and services with commercial and societal impact.
Startups working across almost all areas of science and technology can receive up to $2 million to support research and development, helping de-risk technology for commercial success. America’s Seed Fund is congressionally mandated through the Small Business Innovation Research program. The NSF is an independent federal agency with a budget of about $9.

SBIR/STTR Phase I Programs is sponsored by National Science Foundation (NSF). The NSF SBIR/STTR programs provide non-dilutive funding for cutting-edge technology innovations that address societal challenges. The Space (SP) topic seeks transformative technologies for sustainable space exploration, habitation, or industrialization, which could include in-space research or manufacturing systems, microgravity applications, and photonic devices and materials.
Smart Health and Biomedical Research in the Era of Artificial Intelligence and Advanced Data Science (SCH) is sponsored by National Science Foundation (NSF) and National Institutes of Health (NIH). This interagency program supports transformative, high-risk/high-reward advances in computer and information science, engineering, mathematics, statistics, behavioral, and/or cognitive research to address pressing questions in biomedical and public health. It encourages scientific and engineering innovations by interdisciplinary teams to develop novel methods to collect, sense, connect, analyze, and interpret data from individuals, devices, and systems, enabling discovery and optimizing health. This includes applying AI in healthcare.
NVIDIA Graduate Fellowship Program is a grant from NVIDIA providing up to $60,000 per award to PhD students conducting research that advances accelerated computing and its applications. Now in its 25th year, the program invites nominations from doctoral students pushing the boundaries of artificial intelligence, robotics, autonomous vehicles, and related fields. Recipients receive not only research funding but also access to NVIDIA technology, products, and engineering expertise, along with a mandatory in-person summer internship. Students are nominated by their faculty advisors and selected based on academic achievement and research area alignment.
CalSEED Concept Award is a grant from the California Energy Commission that provides $150,000 in funding to early-stage clean energy innovators in California. The program targets individuals, businesses, and nonprofits developing hardware, software, or integrated solutions at Technology Readiness Levels 2-4. Eligible technology areas rotate each cycle and have included battery recycling and reuse, long-duration energy storage, medium- and heavy-duty vehicle electrification, industrial electrification, and advanced EV charging. Applicants must be located in California, have under $1 million in private funding, and propose innovations that benefit California ratepayers. Concept Award winners also receive professional development resources and access to accelerator programs, and may compete for a subsequent $450,000 Prototype Award.
NSF restarted its SBIR/STTR programs on May 31, 2026 after a multi-month hiatus, with a $250 million FY26 allocation, a Project Pitch portal reopen on June 2, and a first full-proposal deadline of July 27, 2026. The big structural changes: a new Strategic Breakthrough tier that extends invited Phase II companies up to $30 million, and a $40 million pilot for next-generation scientific instrumentation. Phase I tops out at $305K, Phase II at $1.25M, with November 4 and March 4, 2027 windows behind the July 27 first deadline. For deep-tech startups that watched the NIH SBIR omnibus go dark and DARPA pull back on conventional Phase II slots, this is the most consequential reopening of the year — and the Strategic Breakthrough tier is the first time NSF has competed directly with venture capital at growth-stage check sizes.

Read articleCongress appropriated \$8.75 billion for NSF in FY2026, rejecting the administration's proposed 55% cut to \$3.9 billion. But between April and May 2025, DOGE terminated 1,752 grants worth \$1.4 billion, hitting STEM Education (\$888M, 839 grants) and Social, Behavioral and Economic Sciences hardest. Director Panchanathan resigned April 24, 2025; no permanent replacement has been named. Effective December 15, 2025, NSF cut minimum external reviews from three to two, made one internal review allowable, made panel discussions optional, and shrank panel summaries to three to five sentences. Here is what the new NSF actually looks like as a funder, who is being selected against, and how to position a 2026 proposal against the new merit review.
