Space Environment Technologies, LLC

Space Environment Technologies, LLC (doing business as Space Environment Techno), a small business based in Pacific Palisades, California, delivers space weather monitoring, forecasting, and characterization tools to federal agencies as a prime contractor on research and development, SBIR, and federal grant programs. The vendor operates predominantly under Total Small Business set-asides on NASA SBIR Phase I, Phase II, and Phase III awards, and competes full-and-open on sole-source, subscription, and mentoring purchase orders with NASA and NOAA. A Subchapter S corporation registered in SAM.gov since 2002, the company specializes in thermospheric density prediction, satellite drag modeling, solar and geomagnetic index forecasting, and space environment instrumentation — work that spans NAICS 541711 and 541712 (R&D in physical, engineering, and life sciences) and 541690 (Other Scientific and Technical Consulting Services).

NASA's Shared Services Center dominates the customer set, accounting for 70% of recent awards (35 awards, $8.6 million combined potential value) and 83% of the dollars in the portfolio's top-five ranking. The National Oceanic and Atmospheric Administration, Naval Information Warfare Systems Command, Air Force Research Laboratory, and Armstrong Flight Research Center round out the active federal customer base. Concrete work examples include a $1.27 million SBIR Phase II definitive contract (awarded September 29, 2026) for machine-learned nitrogen oxide and carbon dioxide cooling rate profiles and global power models to improve real-time thermospheric density specification; an $84,000 one-year subscription (October 1, 2026, through September 30, 2027) with NOAA for the Jacchia-Bowman-HASDM Solar and Geomagnetic Indices data and support services for TRACSS operations; a $489,793 SGI-HASDM subscription purchase order from Naval Information Warfare Systems Command (completed May 2023); and a $462,633 research grant from NASA (February 2023) for the Automated Radiation Measurements for Aerospace Safety Aeronautical Regional Geospatial Observer System (ARMAS ARGOS) project. Space Environment Technologies also holds a $350,000 Other Transaction IDV from the Defense Advanced Research Projects Agency (awarded September 21, 2022) under the QUIJA program to quantify high-frequency ionospheric noise and improve ionosphere characterization in support of military capabilities.

Federal grant work includes two NOAA project grants as prime recipient — one (September 2024, completing August 2026) for development of a nitric oxide sensor system (NOMAD) to fly on stratospheric drones for continuous monitoring of geomagnetic storm effects on atmospheric density, and one (September 2023, completed February 2024) on the same technology at earlier stage — alongside NASA grants for orbital drag effects research on LEO satellites during geomagnetic storms and the ARMAS ARGOS radiation instrumentation project. The vendor also subcontracts to academic institutions on federal grants; recent sub-award relationships include data assimilation and modeling work with the University of Colorado (dating from October 2024 through March 2026) on SWORD space weather forecasting and SABER instrument data integration, and radiation flight-data provision work with UCLA (October 2024) and University of Maryland Baltimore County (June 2026) on atmospheric and radiation modeling research.

Recent activity shows modest growth — five awards in 2022 rising to eight in 2026 through October — with five awards (combined potential value $2.5 million) reaching ultimate completion inside the next twenty-four months and therefore facing recompete. The vendor places task orders under the GSA Federal Supply Schedule (6 task orders, $464 thousand combined potential value). Service Contract Inventory data show negligible SCI-reportable invoiced revenue across FY2022–FY2025, reflecting the vendor's concentration in R&D grants and contracts rather than commercial service delivery above the SCI $150,000 reporting threshold; FTE trajectory across SCI records spans 0.0 to 0.1 FTEs. The vendor operates as a prime on 90% of its awards and subcontracts to other primes on 10%, with no measurable sub-engagement share on its own prime SCI-reportable contracts. All work is performed at the company's Pacific Palisades headquarters, with coordination and technical advisory support provided by NASA Goddard Space Flight Center personnel on SABER-related mentoring and reprocessing engagements.
