NASA has awarded a contract to MacLean Engineering & Applied Technologies, LLC of Houston to provide simulation and advanced software services to the agency.

The Simulation and Advanced Software Services II (SASS II) contract includes services from Oct. 1, 2025, through Sept. 30, 2030, with a maximum potential value not to exceed $150 million. The contract is a single award, indefinite-delivery/indefinite-quality contract with the capability to issue cost-plus-fixed-fee task orders and firm-fixed-price task orders.

Under the five-year SASS II contract, the awardee is tasked to provide simulation and software services for space-based vehicle models and robotic manipulator systems; human biomechanical representations for analysis and development of countermeasures devices; guidance, navigation, and control of space-based vehicles for all flight phases; and space-based vehicle on-board computer systems simulations of flight software systems. Responsibilities also include astronomical object surface interaction simulation of space-based vehicles, graphics support for simulation visualization and engineering analysis, and ground-based and onboarding systems to support human-in-the-loop training.

Major subcontractors include Tietronix Software Inc. in Houston and VEDO Systems, LLC, in League City, Texas.
