An Assessment of Artificial Intelligence Technologies for Vehicle Management Systems Spacecraft and Vehicles Systems Department, Advanced Sensors & Health Management Systems, Code EV23 Kamara Brown 1, Dr. Mike Watson 2, Dr. Luis Trevino 3 1 Research Associate, George Washington University 2 Principal Investigator, Branch Chief, NASA MSFC 3 Principal Investigator, Artificial Intelligence Scientist, NASA MSFC Data Analysis As NASA moves towards planning deep space missions, there is a need for examining applications utilizing autonomous systems and AI technologies. This will allow space vehicle systems that can make decisions on its on. The intelligent system must dynamically select the “optimum” configurations for supporting such critical subsystems like crew environment, electrical power systems, propulsion systems.
