What happens during a sonic boomAn artist's concept shows the X-59 in flight, a design being developed by NASA and Lockheed Martin to create a faster-than-sound plane with a quieter sonic boom. NASA/Lockheed MartinA sonic boom occurs when an aircraft exceeds the speed of sound. That shock wave is what you hear as a sonic boom. A sonic boom can generate sounds of up to 110 decibels, similar to a thunderclap or explosion strong enough to shatter windows and cause tremors. The Quesst mission seeks to reduce "the loudness of a sonic boom reaching the ground to that of a gentle thump, if it is heard at all," the agency said.

Since the 2003 end of Concorde, of course, flitting quickly across the Atlantic has been a thing of the past. Flights between London and New York take around eight hours, or closer to seven in the other direction. But now, the thought of supersonic travel has been mooted again – by none other than NASA, which reckons that New York-London flight could take as little as 90 minutes in the future. However, NASA is developing “quiet” supersonic aircraft, called X-59s, as part of its Quesst mission. Lockheed MartinSimilar studies to the ones done now, which were carried out a decade ago, shaped the development of the X-59 aircraft, according to Lori Ozoroski, project manager for NASA’s Commercial Supersonic Technology Project.

☆ NASA moves forward with plans for supersonic planes that could fly from New York to London in 1.5 hours

NASA asked private companies to figure out how to make commercial supersonic flight "a reality." Mach 2 to 4 planes, flying up to 3,045 mph, could be used on 50 established flight routes, per NASA. This comes as NASA is starting to test its own X-59 supersonic plane to make sonic booms quieter. To make supersonic flight a reality, it needs to become quieterThe news comes as NASA begins testing its own supersonic plane. NASA/Lockheed MartinThis is an important experiment because non-military supersonic flight over land has been banned by federal regulations for over 50 years in the US.

☆ X-59: NASA’s ‘quiet’ supersonic plane revealed

CNN —If you’ve heard a sonic boom recently, you probably remember it. Now, NASA is working to change those regulations by transforming the boom into a “thump,” paving the way for a new generation of quieter supersonic aircraft. It’s set to take off for the first time later this year, ahead of its first quiet supersonic flight. “It will be significantly quieter than Concorde or any other supersonic aircraft that exist today,” Craig Nickol, senior adviser at NASA Headquarters, told CNN in 2022. However, it’s doubtful that any of them will be able to take advantage of the findings of the Quesst program, which will likely inform the next generation of supersonic aircraft.
