Quieter, greener supersonic travel is the focus of eight studies selected by NASA’s Commercial Supersonic Technology Project to receive more than $2.3 million in funding for research that may help overcome the remaining barriers to commercial supersonic flight.

The research, which will be conducted by universities and industry, will address sonic booms and high-altitude emissions from supersonic jets. 

The titles of the studies and details of the awards are:
