X-57 'Maxwell' Moves To Next Stage Of Development NASA is involved in all kinds of aeronautical projects that aren't strictly space driven. NASA is working on speed and defeating the sonic boom phenomena with the X-59 QueSST project with Lockheed Martin and they are also working on the X-57 'Maxwell' Project. So what is the Maxwell Project? This project is more about having a platform to examine cleaner and more energy-efficient aircraft. With the platform -which is a highly modified Tecnam 2006T- NASA can test and determine the airworthiness of electrified aircraft technologies, including battery technology, electric motor capabilities, as well as distributed electric propulsion.
