INSTITUTION PROFILE / SPACE INDUSTRY
Defense Advanced Research Projects Agency (DARPA)
The research agency that tests new space technology first, and neither regulates nor runs space programmes
DARPA is a research and development agency inside the U.S. Department of Defense. Its mission is to create, and prevent, technological surprise for national security. In space, it funds and demonstrates published research programmes, such as ways to assemble large structures in orbit and a framework for lunar infrastructure. But it does not set space policy or license launches. This profile looks at one question: what DARPA can decide in the space industry, and what it cannot. It does not cover military technology in detail.

1. DARPA in 30 seconds
DARPA is neither a regulator of space nor an operator of a space programme. It is an agency that funds advanced research and takes it far enough to show whether it works. DARPA itself says its programmes focus on the fundamental research needed to establish proof of concept, while transition partners lead implementation, technology transfer and commercialisation Sourced. The same holds in space: DARPA money lets new technology be tried early, but launch licences and safety rules come from the Federal Aviation Administration (FAA), and the total budget is set by Congress Sourced.
2. What kind of body it is: the four types of influence
Institutions in the space industry differ from companies. What separates them is the route by which they influence the industry, and that gives four types. DARPA falls under "Funding", because it pays for research programmes and demonstrations. But the money comes from the defense research budget, and the purpose is national security.
3. What it does in the space industry (published programmes only)
DARPA runs many programmes involving space. This profile covers only those that DARPA has published on its website and that bear on the civil and commercial space industry or on space materials. It does not go into military uses. DARPA cites two contributions of its own to civil space: rocket technology in the Saturn V that took people to the Moon, and the TIROS weather satellites, which it says became the prototype for today's global weather systems Sourced (DARPA's own account). The table shows the position as of 17 October 2026.
| Programme | What it is | Status |
|---|---|---|
| NOM4D Manufacturing and materials in orbit | Explores launching only raw materials and building large structures in orbit, so that designs are not limited by the size of a rocket's cargo fairing. Run by the Defense Sciences Office; started in 2022. On 10 February 2025 DARPA switched its third and final phase from laboratory testing to small-scale orbital demonstrations. One is Caltech's autonomous robotic assembly of a 1.4 m-diameter circular truss (simulating an antenna aperture), carried on Momentus's Vigoride orbital service vehicle on SpaceX's Falcon 9 (Transporter-16), planned for February 2026. The other is the University of Illinois Urbana-Champaign (UIUC) forming a structure from a carbon-fibre sleeve and a liquid monomer, to be carried with Voyager Space to the International Space Station (ISS) on NASA's cargo mission NG-24 (tentatively April 2026) and tested in the station's airlock. We could not find the results of the demonstrations | Sourced (the plans) Not yet confirmed (the results) |
| LunA-10 10-Year Lunar Architecture Capability Study | Imagines a Moon where commercial activity works by 2035 and studies a framework for lunar infrastructure that users can share (power, communications, mobility and so on). Run by the Strategic Technology Office. On 5 December 2023 DARPA selected 14 companies (including Blue Origin, Firefly Aerospace, Northrop Grumman, Redwire, SpaceX, Sierra Space and Nokia of America) for a seven-month study, with a final report in June 2024. DARPA states that the work is for scientific and peaceful purposes under Article IV of the Outer Space Treaty, and that the architecture is not meant to support human exploration or science without commercial value. The programme page now shows "complete" | Sourced |
| DRACO Nuclear thermal rocket demonstration | A space demonstration of a nuclear thermal rocket, which heats propellant with a reactor. NASA is the mission partner. Run by the Tactical Technology Office. The page shows "complete" and is no longer maintained. We could not find why or when it ended | Sourced ("complete") Not yet confirmed (the circumstances) |
| Space-BACN Interconnecting optical links between satellites | Aims at a reconfigurable, multi-standard optical communications terminal that can link satellites built to different optical inter-satellite specifications. Run by the Strategic Technology Office. DARPA also describes the programme in a military context, which this profile does not cover. The page showed no "complete" notice on the date checked | Sourced |
| Budget | US$4.322 billion enacted for FY2026; US$5.039 billion requested by the President for FY2027. How much of this goes to space is not broken out in the sources we checked, and we could not find it | Sourced (the totals) Not yet confirmed (the space share) |
The UIUC demonstration forms a rigid structure from a carbon-fibre tube soaked in a liquid monomer (molecules that have not yet solidified), by igniting one end of the tube so that the reaction spreads on its own. This is called frontal polymerisation. According to DARPA's programme manager, carbon-fibre-reinforced epoxy on Earth is made by bagging the part, infusing resin and heating it in an autoclave. A structure of 100 metres or more cannot be put in an autoclave in orbit, so the team chose a method that spreads the reaction without heating the whole part Sourced (DARPA's account). Our explainers on space CFRP and composites, additive manufacturing in space, and space manufacturing and microgravity give useful background. However, we have not confirmed that it actually worked in orbit Not yet confirmed.
4. How far its influence reaches (powers and geography): what it can and cannot decide
Here is a one-glance split of what DARPA can and cannot do.
| Aspect | What DARPA has | What DARPA does not have |
|---|---|---|
| Powers | Planning programmes and funding them. It can enter contracts, grants, cooperative agreements and other transactions. It also has prize challenges (up to US$10M) and small exploratory awards ("Seedlings") | Licensing launches and reentries (FAA), assigning radio frequencies, and making rules for space. We found no statement that DARPA's mission includes any of these. Putting results into use, buying them and commercialising them are done by transition partners |
| Flow of money | Defense research and development (R&D) funds set by Congress. DARPA receives only R&D funds | The power to set its total budget. The armed services and appropriations committees do that |
| Geography | Wherever U.S. government money reaches. For LunA-10, DARPA says the selected firms include "domestic and international" companies | Power over other countries' rules or other agencies' plans |
| Duration | Programmes have a finite life and run in phases (DARPA's description). LunA-10 was a seven-month study, and DRACO shows "complete" | The role of running a long-term space programme (space agencies do that) |
| Scale | About 250 government staff, nearly 100 programme managers and about 300 research projects (FY2024 financial report). US$4.322 billion enacted for FY2026 | Power to move the whole space industry. We could not find how much goes to space |
US$4.322 billion is DARPA's whole budget, not a space-only figure. DARPA's own page gives the enacted budget for FY2026 (the U.S. fiscal year runs from October to September) as US$4.322 billion, and the President's budget request for FY2027 as US$5.039 billion (a request has not yet passed Congress and is not an enacted amount) Sourced. The FY2024 financial report says "approximately a $4.1 billion budget", so the amount differs from year to year. We found no breakdown by programme (NOM4D and so on) Not yet confirmed.
5. Related organisations and companies
DARPA runs its programmes through six technical offices by field. Its published space programmes sit in three of them. Fig. 3 shows only relationships documented in primary sources.
Of the names that matter to this series' company profiles, the LunA-10 selectees include Blue Origin, Firefly Aerospace, Northrop Grumman, Redwire and SpaceX (announced 5 December 2023). This is participation in a study, and does not mean DARPA adopted or endorsed any company's products. The tie to NASA is confirmed only as far as DARPA calling NASA its "mission partner" on DRACO. Our explainers on lunar exploration and Artemis, on lunar resources and ISRU, and on national space strategies and regulation give useful background.
6. Outlook
| What can be read from the sources | Supporting primary source | Status |
|---|---|---|
| What actually happened to the NOM4D in-orbit demonstrations (Caltech's truss and UIUC's composite forming) | DARPA's announcement of 10 February 2025 gives plans for February 2026 and April 2026 (tentative). We could not find whether they took place, or their results | Not yet confirmed |
| Whether DARPA's FY2027 budget will reach US$5.039 billion | DARPA's page calls it the President's request, not an amount enacted by Congress | Not yet confirmed |
| Why DRACO is shown as complete, and what comes next for nuclear thermal rockets | DARPA's DRACO page says only "complete". We could not find the reason or the date | Not yet confirmed |
| DARPA's space research will probably continue to centre on demonstrations that test whether commercial users can adopt a technology | NOM4D's 2025 shift from the lab to orbital demonstrations, LunA-10's focus on commercial lunar infrastructure, and DARPA's statement that transition partners carry out implementation | Inference |
7. Glossary
- Programme manager
- The person at DARPA who designs a research programme and is responsible for its budget and direction. Terms are short (generally 3 to 5 years, per DARPA).
- Transition partner
- The agency or company that actually uses DARPA's results and carries out implementation, procurement or commercialisation.
- Technical office
- One of DARPA's six technical divisions. Its published space programmes sit in three: Defense Sciences, Strategic Technology and Tactical Technology.
- Fiscal year (U.S.)
- October to September. FY2026 is October 2025 to September 2026.
- Request versus enacted
- A request is the budget the President sends to Congress; enacted is the amount Congress approves. A request does not always become law as submitted.
- Frontal polymerisation
- A forming method in which igniting one end of the material makes the hardening reaction travel by itself to the other end. No large oven is needed.
- In-space manufacturing
- Launching raw materials and building structures in space, so that designs are not limited by the size of a rocket's cargo fairing.
- FAA
- The U.S. Federal Aviation Administration. It licenses commercial launches and reentries and sets safety rules.
