The NASA Exploration Systems Simulations (NExSyS) team supplies simulation and analysis products to assess the design and performance of vehicles early in the development process. Models based on proposed vehicle designs are placed in simulated Earth, Lunar, Martian, or interplanetary environments while the performance of propulsive, GN&C, ECLSS, thermal, and power systems are evaluated under a variety of operational conditions. These simulations run on computational platforms ranging from laptop computers to high end virtual environments and provide analytical feedback to vehicle designers, mission concept evaluation capabilities to systems engineers, and operational insight to flight crew.
