Eureka Scientific, Inc.

Eureka Scientific, Inc., a small disadvantaged business headquartered in Piedmont, California, performs astrophysics and space science research and data analysis for NASA and the National Science Foundation almost exclusively as a prime grant recipient, with recent award volume growing from 19 grants in 2022 to 33 in 2025. The firm does not hold federal contracts or seats on government-wide vehicles; 99 percent of its federal footprint consists of research grants under which it conducts observational astronomy, archival data analysis, and technical consulting in X-ray spectroscopy, ultraviolet photometry, machine learning, and computational modeling.

Eureka Scientific's customer base is nearly monolithic. NASA accounts for 86 percent of recent awards by count — 168 grants from NASA's Shared Services Center alone (combined potential value $9.3 million), plus 26 awards from NASA Goddard Space Center ($1.5 million) and 15 from NASA Headquarters ($2.9 million). The National Science Foundation placed 8 recent awards; the National Institute of Standards and Technology placed 1 award ($609 thousand, a firm-fixed-price purchase order for site preparation and equipment support for NIST's ESO STARS project in Chile through December 2028). The top five customer agencies account for 86 percent of recent awards and 91 percent of combined potential value, but the concentration is driven almost entirely by NASA's Shared Services Center, which funds the bulk of Eureka Scientific's research grant pipeline.

Recent representative grant work spans astrophysics investigations tied to space observatory data. A $374,709 grant from NASA (awarded March 2025, completion March 2028) supports comprehensive archival investigation of X-ray emission from core-collapse supernovae. A $735,718 grant (February 2025, completion January 2028) funds research establishing empirical and physics-based relationships between coronal dimming and coronal mass ejections on exoplanet host stars using UV or X-ray observatories. A $857,399 grant (June 2022, completion June 2025) supports a 15-year X-ray variability survey of BAT active galactic nuclei. Smaller grants in the $40,000–$130,000 range fund Chandra, XMM-Newton, NuSTAR, Swift, and NICER data analysis and paper writing on topics including tidal disruption events, supermassive black holes, neutron stars, and circumgalactic medium properties. Recent grant awards from NSF include participation in the NANOGrav Physics Frontier Center as a sub-recipient under Oregon State University (awards from October 2025, June 2025, and April 2025), and a $299,896 NSF project grant (January 2026 through January 2028) for balanced science program execution aligned with National Academies guidance.

Activity has grown steadily year over year across the 280 total prime and sub awards in the source data, with 2025 yielding 33 grants and the first quarter of 2026 showing 9 grants already recorded. Forty-six awards (combined potential value $2.7 million) reach ultimate completion within the next twenty-four months, exposing the vendor to significant recompete activity but also indicating a healthy pipeline of renewals and follow-on grants from its core NASA customer. Four sub-awards place Eureka Scientific in supporting roles — three as a sub-recipient under Oregon State University's NANOGrav Physics Frontier Center grant (funded by NSF), and one under Spectral Sciences, Inc. on a data analysis task. The firm competes in full-and-open research grant solicitations without set-aside designations; small disadvantaged business status appears in award descriptions but does not anchor its competitive posture. Top NAICS codes reflect the research profile: Office Administrative Services, Research and Development in Physical Engineering and Life Sciences, and Space Research and Technology. The award portfolio consists almost entirely of project grants (Assistance Type: Project Grant) with performance periods of one to three years, structured as recompetable annual or multi-year solicitations (ROSES, NuSTAR, ADAP, IXPE, and other NASA research opportunity announcements) rather than standing contract vehicles or indefinite-delivery arrangements.
