Space startups can access non-dilutive funding from 8+ programs, ranging from $75K SpaceWERX Phase I awards to $10M+ DARPA STO contracts, with NASA SBIR ($150K Phase I) and DIU Space ($500K-$5M OTA) in between. The space industry is receiving more government funding than at any point since Apollo, and the pathways are wider than most founders realize. But each program has different requirements, award sizes, and strategic implications.
This guide maps the full landscape -- from $75K SpaceWERX Phase I awards to $10M+ DARPA contracts -- so you can target the programs that actually fit your technology and stage. Cada Partners has built grant roadmaps for space startups spanning satellite communications, on-orbit servicing, and launch technology.

NASA SBIR: the anchor program for space science
NASA's SBIR program is the primary grant pathway for space startups focused on exploration, Earth observation, and space science. NASA releases an annual solicitation with specific subtopics organized by mission directorate.
Key details:
- Phase I: ~$150,000 for 6 months
- Phase II: ~$750,000 for 24 months
- Phase I-E (Extended): Bridge funding between Phase I and II
- Sequential Phase II: Additional Phase II awards for continued development
NASA's mission directorates (each has SBIR topics):
- STMD (Space Technology) -- in-space manufacturing, power systems, propulsion, thermal management
- SMD (Science) -- instruments, sensors, data analysis for Earth science, planetary science, astrophysics
- EOMD (Exploration and Operations) -- crew systems, life support, EVA technology, lunar surface systems
- ARC (Aeronautics) -- advanced air mobility, hypersonics, autonomous flight
The NASA advantage beyond money: Phase II awardees can access NASA facilities (wind tunnels, vacuum chambers, test ranges), technical mentorship, and potential flight opportunities. A NASA SBIR can lead to a spot on a rideshare mission or an ISS experiment -- validation you can't buy.
The limitation: NASA SBIR awards are among the smallest ($150K Phase I vs. $305K at NSF). For capital-intensive hardware companies, Phase I barely covers materials costs. The strategic value is often more important than the dollar amount. This is why Cada typically recommends pairing NASA SBIR with NSF or SpaceWERX to cover both the funding and strategic angles.
SpaceWERX: the Space Force's innovation arm
SpaceWERX is the Space Force equivalent of AFWERX (Air Force). It manages SBIR/STTR for national security space applications.
Key programs:
- Open Topic SBIR. Bring your own technology and pitch a Space Force use case. $75K Phase I, $1.25M Phase II. Continuous submissions.
- Specific Topic SBIR. Space Force publishes defined technical needs. Submit to matching topics.
- Orbital Prime. Focused program for on-orbit servicing, assembly, and manufacturing (OSAM) technology. Targets active debris removal, satellite servicing, and in-space construction.
SpaceWERX vs. NASA SBIR:
- SpaceWERX is defense-focused (national security space). NASA is exploration and science-focused.
- SpaceWERX uses the AFWERX model (fast, customer-discovery Phase I). NASA uses traditional SBIR (R&D-focused Phase I).
- SpaceWERX Phase I is smaller ($75K vs $150K) but faster (~90 days vs 6-9 months).
- SpaceWERX has the STRATFI/TACFI bridge to scale ($3M-$15M). NASA has Phase II-E but no equivalent bridge program.
Best for: Companies building technology for military satellite operations, space domain awareness, GPS, SATCOM, space cybersecurity, responsive launch, or on-orbit servicing.
DARPA STO and TTO: breakthrough space technology
DARPA's Strategic Technology Office (STO) and Tactical Technology Office (TTO) both fund space-relevant research through BAAs.
STO focus areas:
- Resilient space communications (alternatives to GPS dependency)
- Space domain awareness (tracking objects and threats in orbit)
- Responsive launch (rapid deployment of satellites)
- Multi-domain command and control involving space assets
TTO focus areas:
- Autonomous space systems
- Space-based sensing and ISR
- Reusable space vehicle technology
How to apply: DARPA uses BAAs and SBIR topics. Start by finding the relevant BAA on SAM.gov, then email the program manager. Awards range from $250K (SBIR Phase I) to $10M+ (BAA contracts).
What space funding exists beyond SBIR?
Space Development Agency (SDA). SDA builds the Pentagon's next-generation satellite constellation (Proliferated Warfighter Space Architecture). They award large contracts ($10M-$100M+) for satellite buses, payloads, ground systems, and integration. Not an SBIR program -- this is procurement. Best for companies with flight-ready or near-flight-ready hardware.
National Reconnaissance Office (NRO). The intelligence community's satellite agency. Limited public visibility into funding opportunities, but NRO has engaged commercial space companies through study contracts and prototype agreements. If your technology is relevant to ISR and imagery, NRO is worth exploring through their industry days and SAM.gov postings.
DIU Space Portfolio. $22.1M allocated to resilient space communications in FY2026. The Hybrid Space Architecture (HSA) pilot is testing a "hack-proof" space internet with vendors including Aalyria, Anduril, Astranis, Planet Labs, and Palantir. DIU's OTA prototype agreements ($500K-$5M, awarded in 60-90 days) are the fastest path to a defense space contract.
Prizes and competitions
NASA iTech. Identifies technologies with potential dual-use space applications. Not a grant -- more of a showcase and accelerator that can connect you to NASA programs and investors.
XPRIZE. Periodic large-scale competitions with space themes (Lunar Landing, Mars missions). Prize amounts can reach $10M+. Highly competitive but high-visibility.
NASA Centennial Challenges. Specific technical challenges (3D printing habitats, sample return, lunar excavation) with prizes from $100K to $5M+. Open to anyone -- no SBIR eligibility required.
Which space program fits your type of startup?
How do ITAR and security clearances affect space grant applications?
ITAR (International Traffic in Arms Regulations) affects many space technologies. Satellites, launch vehicles, and certain components are on the US Munitions List. If your technology is ITAR-controlled:
- You cannot share technical data with foreign nationals (including employees) without a license
- Export of hardware or software requires State Department approval
- This affects who you can hire, who you can partner with, and where you can manufacture
For SBIR applications: ITAR status doesn't prevent you from applying, but it may affect your subcontracting plans and team composition. If you're unsure about your technology's classification, consult an ITAR attorney before submitting proposals that involve international partners.
Security clearances: Most NASA SBIR work is unclassified. SpaceWERX and DARPA space programs may involve classified work at later stages. DIU prototype work is typically unclassified. Clearance requirements are specified in each solicitation.
Where should space startups start (and in what order)?
For most space startups, the recommended sequence:
- NASA SBIR -- apply to the annual solicitation matching your technology to the right mission directorate. This is your anchor application.
- SpaceWERX Open Topic -- if you have a defense space angle, submit in parallel. Fast feedback.
- DARPA STO -- if your technology is breakthrough-level, email the relevant PM and gauge interest.
- DIU -- if your technology is commercial-ready (TRL 5+) and has defense utility.
