Regular commercial supersonic flight ended with the iconic Concord in 2003 but NASA in particular has been pushing research into a new class of quieter, greener high-speed aircraft.

This week the space agency said it invested $2.3 million for eight research projects that will address sonic booms and high-altitude emissions from supersonic jets.
NASA’s Commercial Supersonic Technology Project, which picked the new projects, focuses on developing sonic boom reduction methods and defines the necessary approaches or techniques for objectively assessing the levels of sonic boom acceptable to communities living in the vicinity of future commercial supersonic flight paths.
