Power, Control, and Communication System Initial Design and Analysis for NASA Gateway Human Landing System

NASA is currently leading an effort to return to the moon with a sustained human presence. This project describes simulations and recommendations for the Human Landing System (HLS) of NASA’s Gateway station architecture. Analysis is performed for 3 critical systems where technology advancements or the unique mission requirements of this architecture pose new design challenges: power, control, and communication. Based on research and simulation, design recommendations for each of these systems are made, and design tradeoffs to be considered are given.
Recommendations for the design of 3 systems for the HLS that are critical to its operation, and for which significant advances in technology or new mission requirements drive new design considerations compared to prior work. Requirements provided with NASA’s solicitation drive these recommendations and the analyses used to evaluate them in this project. These systems are power, communications, and control. We describe the analyses and simulations which led to these recommendations, the tools and methods we used, tradeoffs that could be made to alter the recommendations, and other considerations to keep in mind with respect to these systems.
