How NASA Modeled Artemis I in MATLAB and Simulink

The Space Launch System (SLS) rocket is designed to carry humans into deep space. Using MATLAB^® and Simulink^® for simulation and validation, the complex mission management logic is designed to ensure that the SLS can correctly respond to nominal and off-nominal events.

On Artemis I, the SLS carried the Orion crew capsule to orbit. Orion is the distance-record owner of a human-rated spacecraft, having traveled approximately 450,000 km from Earth. The Orion Electrical Power System, which powered the spacecraft during its 25 ½ day trip, was modeled in MATLAB and Simulink to validate the design. The Guidance, Navigation and Control system (GN&C), which told the spacecraft where to go, was designed in MATLAB and Simulink using Model-Based Design.
