Completed TRL 2 (started at 1, targeting 2)
Some of the key technical challenges that will be addressed during the development of OASiS includes 1) developing OASiS within an existing high-fidelity, modular simulation framework – the Langley Standard Real-time Simulation in C++ (LaSRS++), 2) creating a library of characterized simulation models based on existing OSAM hardware, 3) designing simple methods to incorporate new OSAM hardware, environmental models, and system functionality for OASiS users, and 4) validating the accuracy of OASiS test data between simulated OSAM operations and analog lab hardware setups. The main objective of this project is to demonstrate the simulation of a key OSAM operation with OASiS models against analog hardware setups, which will be accomplished by 1) holding critical conversations with partners to determine OASiS functionality, software architecture, and initial OSAM operational scenarios to model, 2) modeling, integrating, and testing OSAM robots and control systems between OASiS and real hardware, 3) advancing metrology system modeling from MeSSE, and 4) advancing modeling for manipulation of rigid multi-body structures on-orbit.
The NASA On-Orbit Servicing, Assembly, and Manufacturing (OSAM) National Initiative has identified a critical need for developing OSAM modeling and simulation capabilities. A high-fidelity simulation environment could be used to 1) analyze and develop large-scale OSAM mission architectures that would otherwise be challenging to fund and test in Earth-based facilities, 2) reduce OSAM mission development costs, and 3) ensure the successful servicing, assembly, and manufacturing of vital research-enabling observatories and habitats in space, such as the In-space Assembled Telescope and the Lunar Gateway. The goal of this project is to develop the OSAM Architecture Simulation System (OASiS). OASiS will provide mission developers with a modular, high-fidelity simulation environment in which to rapidly prototype and evaluate their OSAM technologies and operational concepts, enabling the verification and validation of large-scale OSAM mission architectures prior to launch.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
