NASA SBIR Phase II carries the work from a successful Phase I into technology maturation inside the agency's space and aerospace portfolio. It sits in NASA's broader SBIR/STTR ladder, where early feasibility can move into development, then transition support, and eventually commercialization. By Phase II, the agency expects a result that is already anchored in NASA-relevant evidence. Awards run from $750,000 to $1,000,000, with a median actual award of $850,000, and the route uses a 24-month performance period. Eligibility remains limited to U.S.-incorporated for-profit small businesses, 51 percent U.S. ownership, and TRL 4 to 7 work in space or aerospace. The program follows the BAA model, only Phase I awardees may apply, and the route can also pair with up to $50,000 in TABA support. The best fit is a company that can show Phase I traction, explain why the technology is now ready for development, and map the work to a NASA transition path. Strong proposals stay concrete about engineering milestones, keep the scope credible over 24 months, and show that the project can move beyond research into a real mission use case.
