Radiation and Ejecta Berm Modeling & Simulation

This contract involves the computational modeling of lunar berms designed to provide radiation shielding and protection against high-velocity ejecta on the lunar surface, utilizing finite element analysis and environmental simulations. The work aims to develop accurate models that simulate the behavior of regolith-based structures under lunar conditions, including cosmic and solar radiation exposure, micro-meteoroid impacts, and thermal cycling, to support safe and sustainable human lunar habitats. The modeling will incorporate material properties of lunar soil, structural dynamics under extreme environments, and multi-physics interactions to evaluate berm effectiveness and optimal configurations. Issued as a subcontract under a Total Small Business Set-Aside, the opportunity is open exclusively to small businesses as defined by the SBA, with the NAICS code 541330 indicating engineering services. The contract is sponsored by NASA Shared Services Center on behalf of the National Aeronautics and Space Administration, with responses due by May 21, 2026. Performance is expected to take place in support of NASA’s lunar exploration objectives, though the specific location of performance is not designated. The project underscores NASA’s focus on advancing in-situ resource utilization and passive protection technologies for upcoming Artemis missions and long-duration lunar surface operations.
