NASA is always looking to change what’s possible in space. The NASA Innovative Advanced Concepts (NIAC) program funds innovative aerospace concepts that could enable and transform future missions. Each year, NASA issues multiple NIAC solicitations and grant awards. Researchers across government, industry and academia with high impact ideas should consider submitting a proposal.

The NIAC program supports visionary research ideas through multiple progressive phases of study.

Phase I studies are efforts up to 9 months to explore the overall viability and advance the Technology Readiness Level (TRL). Eligible recipients of Phase I awards can propose for a follow-on Phase II study.

Phase II develops concepts for up to two years. Researchers must prepare a roadmap for further development, but are not expected to fully advance the technologies to a level required for NASA or commercial transition.

Phase III continues the exploration and development for another two years. The final phase is designed to strategically transition NIAC concepts with the highest potential impact for NASA, other government agencies or commercial partners.
