Abstract	This presentation gives an overview of the design and use of a generalized lunar lander simulation that is supporting NASA’s Artemis Program. The HLS CrewCo Lander Simulation (HCLS) is being developed for the Crew Compartment Office (CrewCo) at the Johnson Space Center (JSC) to provide insight into the challenges associated with returning humans to the Lunar surface. The primary use of the simulation has been for assessing crew displays and handlings qualities of a lunar lander during the Deorbit, Descent, and Landing (DDL) landing phase but is being expanded to support Lunar Ascent and Rendezvous and Proximity Operations (RPO) as well. The simulation architecture provides a flexible framework that allows for quickly prototyping and evaluating various aspects of a piloted lunar landing system. It has been configured to model a generalized lunar lander based on a government reference design but can be easily modified to model vendor designs as well. The simulation has also been used to support informal handling qualities evaluations to help NASA better understand what will be needed to meet the required system performance for manual control. The purpose of the HCLS is not to design the ideal lunar lander, but rather to understand the strengths and weaknesses of vehicle design choices.
