If you build space hardware in the United States and you have not yet touched NASA's SBIR and STTR programs, this is usually where the ladder starts. It is non-dilutive — NASA does not take equity — and it funds the awkward stage between a lab demo and a product that can survive a launch.
The phase ladder. Phase I is a short feasibility study, roughly $150,000 over six months, to prove the core idea is credible. Phase II is where the money gets real: winners of a strong Phase I are invited to scale the work, typically $850,000 or more over two years, to build and test a prototype. Phase III is commercialization — you sell the matured technology to NASA or another customer, using no SBIR funds. The programs are near-identical; the difference is that STTR requires a formal partnership with a research institution such as a university, while SBIR does not.
What changed for 2026. NASA moved away from a single annual solicitation toward a Broad Agency Announcement (BAA) with phased appendices released across the year, so there are multiple entry points rather than one cliff-edge deadline. The BAA was released in spring 2026 and the framework runs through 2027, with Appendix A and subsequent appendices carrying the actual numbered topics. Practically: subscribe to the alerts on the Information Hub, watch for the appendix that carries your subtopic, and note that Phase I windows have run to deadlines like 21 May 2026 (confirm the exact date and time zone on the current appendix — NASA publishes it in Mountain and Eastern time).
Match the subtopic, not the theme. Reviewers score against the exact wording of the numbered subtopic. Quote its language back, name the NASA mission it feeds, and state the Technology Readiness Level you enter and exit at. A brilliant idea filed under the wrong subtopic scores as off-topic.

Everything routes through NASA's SBIR/STTR Information Hub, which links the BAA document and the NSPIRES electronic proposal system. Before you can win a dollar you need the boring registrations done — a SAM.gov entity registration, a SBA Company Registry number, and NSPIRES accounts for the firm and every named participant. These take days to weeks, so start them the moment you decide to bid, not the week of the deadline.
Reading a topic like a reviewer. Each subtopic is written by a NASA technologist who has a specific mission gap in mind. Your job is to prove you close that gap. State the Technology Readiness Level you start and end at, name the mission or program the work feeds, and be honest about risk — reviewers trust a proposal that names its hardest problem over one that pretends there isn't one. Keep the commercialization story concrete: who buys this after Phase II, and why.
SBIR/STTR is not the only door — it sits alongside the wider STMD solicitation slate — but for most early space-hardware teams it is the cleanest first rung: real money, no dilution, and a paper trail that makes every later program take you seriously.
