Space SBIR/STTR topics and deadlines

Non-dilutive money for space startups: open SBIR and STTR opportunities that are space work, soonest deadline first, each linked to where you apply. Deadlines are the agency's; check the source before you plan around one.

Space SBIR/STTR notices on SAM.gov

SAM.gov

Agencies also post SBIR and STTR solicitations, pre-solicitations and special notices on SAM.gov. These are the open ones our space filter accepts, from the procurement watch (SAM.gov access is limited by an API quota, so the list refreshes every few days, not continuously).

No open space SBIR/STTR notice on SAM.gov in the watch right now.

Where the other topics are published

SBIR.gov's public API has refused requests since August 2026, so NASA and civil-agency topics are not copied here. Their own portals:
