About the company
Stone Aerospace, Inc., a Texas-based small disadvantaged business, develops cryobots, thermal management systems, and propulsion technologies for subsurface space exploration as a prime recipient on NASA SBIR Phase I and II contracts and federal research grants, with recurring work as a sub-recipient on university-led NASA science grants. The company competes exclusively under total small business set-asides and operates from its facility in Del Valle, Austin, Texas as a manufacturer of goods and for-profit organization.
Stone Aerospace's capability portfolio centers on advanced robotic systems and thermal technologies for extreme-environment exploration. Recent prime work includes an $849,998 SBIR Phase II award from NASA's Shared Services Center (CFDA 43.001) for sediment sequestration systems in hot water drilling cryobots, completion targeted July 4, 2025; a $149,973 SBIR Phase I contract from the same center awarded September 29, 2025 for the Mars Atmospheric Convective Heat Expulsion Engine (MACHINE), due March 27, 2026; and a $149,966 SBIR Phase I purchase order from August 2023 for vertical motion control systems for cryobots designed to explore subsurface oceans on icy moons like Europa. The company also holds a $166,690 NASA Innovative Advanced Concepts project grant (CFDA 43.012) awarded April 20, 2026 through the Space Technology Mission Directorate for early-stage feasibility studies on space technology innovation. As a sub-recipient, Stone Aerospace operates the Europa Tower cryo-vac-ice chamber facility under multiple University of Florida and University of Alabama research grants, hosting experiments on biosignature preservation in extreme radiation and cryogenic conditions simulating Europa and Enceladus environments.
Customer concentration is nearly absolute: NASA's Shared Services Center accounts for 24 of 29 total awards (97% of recent awards) with $19.3 million combined potential value. The remaining awards split between NASA Headquarters, NASA's main agency entity, and the National Institutes of Health. Prime awards (83% of the footprint) flow through NASA SBIR programs and Space Technology Mission Directorate grants; sub-recipient work (17%) anchors to university planetary science and astrobiology missions. Activity has accelerated in recent years — one award in 2022-2024 versus five in 2025 — with only one award facing recompete completion within the next twenty-four months, indicating a runway of active work extending beyond mid-2027. The company's award portfolio carries combined obligated dollars of $46.9 million against combined potential value of $24.3 million, reflecting upfront performance on multi-phase SBIR sequences and multi-year grant cycles.
