NASA is a relatively small federal agency by headcount but a substantial buyer thanks to the concentration of contracted activity in its mission programmes. The contracting model is heavily centre-based: each of the major field centres runs its own procurement office with delegated authority for the mission portfolio assigned to that centre. Johnson Space Center handles crewed-spaceflight operations and the Mission Control complex; Kennedy Space Center handles launch operations, processing, and the spaceport; Marshall Space Flight Center handles propulsion and the Space Launch System; Goddard handles a large share of Earth- and space-science satellites; and the Jet Propulsion Laboratory (operated by Caltech as an FFRDC) handles deep-space robotic missions. From a vendor perspective, NASA contracting is unusually concentrated — major programmes like Artemis, Gateway, the Commercial Crew programme, and the science-mission flagships are dominated by a handful of large primes (Boeing, Lockheed Martin, Northrop Grumman, SpaceX, Aerojet Rocketdyne, Ball Aerospace, Maxar). For small and mid-sized vendors the most productive paths are subcontracting under those primes, the NASA SBIR/STTR programme (one of the larger SBIR programmes in the federal government), and direct contracts for ground-systems, IT, mission-operations support, scientific data analysis, engineering support services, and centre operations. The Information Technology Procurement Office (ITPO) runs the Solutions for Enterprise-Wide Procurement (SEWP) GWAC, which is one of the most popular federal IT procurement vehicles across all of government — not just NASA. Construction and facilities work at NASA centres is contracted locally by each centre. Vendors targeting NASA should align with 541715 (R&D), 541330 (engineering), 336414 (guided missile and space vehicle manufacturing for hardware integrators), and 541512 (IT). The NASA Office of Small Business Programs runs Mentor-Protégé and outreach programmes.

Main buying offices within NASA
NASA contracting is delivered through a network of buying offices, each with its own delegated authority and mission focus:
- Johnson Space Center (JSC) — Houston
- Kennedy Space Center (KSC) — Florida
- Marshall Space Flight Center (MSFC) — Alabama
- Goddard Space Flight Center (GSFC) — Maryland
- Jet Propulsion Laboratory (JPL) — California (FFRDC)
- Glenn Research Center — Ohio
- Langley Research Center — Virginia
- Ames Research Center — California
Primary NAICS codes for NASA work
Most NASA contract awards are issued under a relatively concentrated set of NAICS codes. Vendors should align at least one primary NAICS to the work they target:
Annual contracting spend
Approximately $20 billion per year — heavily concentrated in a small number of large prime contractors. Spending is distributed unevenly across the buying offices listed above, with the largest dollars concentrated in major weapons systems, infrastructure, healthcare, or mission-critical R&D programmes depending on the agency.
Focus areas where NASA buys most heavily
- Crewed spaceflight (Artemis, Gateway, ISS)
- Robotic planetary and Earth science missions
- Space launch services (commercial and government)
- Aeronautics research
- Space technology development
- Mission operations and ground systems
How to start bidding on NASA contracts
The first step for any federal contracting target is an active SAM.gov registration with a Unique Entity ID, current representations & certifications, and selected NAICS codes aligned to the work you do. Beyond that, NASA-specific paths typically include: registering on the agency-specific vendor portals where they exist, pursuing the relevant socioeconomic certifications (8(a), HUBZone, SDVOSB/VOSB, WOSB/EDWOSB), and identifying the relevant GSA Schedule or government-wide IDIQ vehicles your work falls under. For larger or specialised programmes, subcontracting under an established prime contractor on an existing IDIQ is often the most accessible entry point. Our SAM.gov registration guide and 8(a) eligibility guide walk through the foundational steps in detail.
Finding live NASA solicitations
Every NASA solicitation above the simplified acquisition threshold is published on SAM.gov, but the native search experience is well-known for being slow and difficult to filter. WinAContract maintains a NAICS- and agency-aware search layer over SAM.gov data, with saved searches, email alerts on new postings, and structured filtering by set-aside, deadline, and contract value. See our SAM.gov alternative, federal contract search, and best SAM.gov alternatives pages for context.
