Quesst is NASA's mission to show the X-59 can fly supersonic without generating loud sonic booms and survey what people hear when it flies overhead. Reaction to the quieter sonic "thumps" will be shared with regulators who will then consider writing new rules to lift the ban on faster-than-sound flight over land.

Advanced Air Mobility is NASA's mission to help emerging aviation markets safely develop an air transportation system that moves people and cargo between places previously not served or underserved by aviation, using revolutionary new aircraft that are only just now becoming possible thanks to converging technologies.

NASA is committed to supporting the U.S. climate goal of achieving net-zero greenhouse gas emissions from the aviation sector by 2050. Under the Sustainable Flight National Partnership, NASA is leading federal agencies and industry to accelerate the development of sustainable technologies. 

NASA is working with the Federal Aviation Administration and others to transform air traffic management systems to safely accommodate the growing demand of new air vehicles entering the airspace, enabling them to perform a variety of missions no matter what airspace that mission may require.
